BEHAVIOURAL ASPECT OF MANAGEMENT ACCOUNTING IN NIGERIAN COMPANIES: A STUDY OF ANAMCO, EMENITE NIGERIA PLC ENUGU AND NIGERIAN BREWERIES PLC ENUGU

CHAPTER ONE: INTRODUCTION

1.1 Background of Study

The behavioural aspect of management accounting represents a fundamental shift from the traditional conception of accounting as a purely technical, number-driven discipline to an understanding that recognises accounting systems as social phenomena that shape and are shaped by human behaviour. Unlike financial accounting, which focuses on external reporting to shareholders and regulators, management accounting is primarily concerned with providing information for internal decision-making, planning, control, and performance evaluation. The behavioural dimension acknowledges that management accounting systems are not neutral technical tools but rather instruments that influence how managers and employees think, act, and interact within organisations. This recognition has profound implications for organisational effectiveness, particularly in the Nigerian business environment where cultural, structural, and institutional factors create distinctive behavioural dynamics (Otley, 2016).

The origins of behavioural management accounting can be traced to the recognition that the assumptions underlying traditional management accounting—that individuals are rational economic actors who respond predictably to financial incentives—are empirically inadequate. Research spanning several decades has demonstrated that managers and employees respond to accounting information in ways that are shaped by cognitive limitations, motivational factors, social pressures, and cultural values (Hopwood, 1972). Budgets, for example, may be manipulated through the creation of budgetary slack; performance measures may induce dysfunctional decision-making when individuals focus on measured dimensions to the exclusion of unmeasured but important activities; and participative budgeting processes may generate either commitment or gaming depending on how they are designed and implemented. These behavioural responses are not anomalies but predictable consequences of how accounting systems interact with human psychology and organisational context.

In the Nigerian context, the behavioural aspects of management accounting have received relatively limited scholarly attention despite the country’s status as Africa’s largest economy and the presence of a substantial manufacturing sector. Nigerian companies operate within a distinctive institutional environment characterised by infrastructure deficits, regulatory volatility, currency instability, and cultural values that emphasise collectivism, power distance, and long-term relationships (Okike, 2007). These environmental factors shape how managers perceive and respond to accounting information in ways that may differ substantially from the patterns documented in developed economy research. Understanding these distinctive behavioural dynamics is essential for designing management accounting systems that are effective in the Nigerian context rather than simply importing practices developed elsewhere.

The three companies selected for this study—ANAMCO (Anambra Motor Manufacturing Company), Emenite Nigeria PLC, and Nigerian Breweries PLC Enugu—represent different industrial sectors, ownership structures, and organisational histories that provide a rich comparative basis for examining behavioural aspects of management accounting. ANAMCO, established in Enugu as a joint venture between the Nigerian government and Daimler-Benz of Germany, represents the legacy of Nigeria’s import substitution industrialisation strategy and the challenges of managing state-influenced enterprises. Emenite Nigeria PLC, a building materials manufacturer, represents a Nigerian-owned company operating in a competitive commodity market where cost control and operational efficiency are critical success factors. Nigerian Breweries PLC, as part of the multinational Heineken group, represents a company operating under global management accounting practices adapted to the Nigerian environment.

ANAMCO’s history provides a particularly instructive case for examining behavioural management accounting issues, as the company experienced the tensions between government ownership objectives and commercial viability. Established in 1977 with the aim of assembling commercial vehicles and later passenger cars, ANAMCO operated under a governance structure that included substantial government representation on its board and management team. Management accounting in such a context serves multiple constituencies—government owners concerned with industrial policy objectives, private partner Daimler concerned with technical standards and profitability, and local managers navigating between these sometimes conflicting expectations. The behavioural implications include questions about how accounting information is used in performance evaluation when owners have multiple objectives beyond profit maximisation, and how budgetary processes accommodate the pressures of government funding cycles (Uche, 2008).

Emenite Nigeria PLC, founded in 1963 as a building products manufacturer in Enugu, represents a Nigerian enterprise that has weathered the country’s economic turbulence over six decades. The company produces fibre cement roofing sheets and other building materials for a market characterised by price sensitivity, informal sector competition, and cyclical demand tied to construction activity. For a company like Emenite operating in a competitive commodity market, management accounting systems serve critical functions in cost control, pricing decisions, and operational efficiency measurement. The behavioural aspects include how cost information is used to motivate production workers, how variance analysis influences supervisor behaviour, and how performance targets are set and communicated in a context where global best practices may conflict with local labour market realities (Agbaje and Umoren, 2015).

Nigerian Breweries PLC, established in 1946 and now part of Heineken International, represents the most sophisticated management accounting environment among the three study companies. As a subsidiary of a multinational corporation, Nigerian Breweries operates under global financial reporting and management accounting standards that have been developed across Heineken’s worldwide operations. The behavioural aspects of management accounting in this context include how locally developed accounting information is integrated with global performance management systems, how local managers respond to targets set by regional or headquarters executives, and how cultural differences between Nigerian and European management styles influence the interpretation and use of accounting information. The Enugu brewery, as one of Nigerian Breweries’ operational facilities, provides a specific site for examining how group-level management accounting practices are implemented at the operational level (Emmanuel, Otley, and Merchant, 1990).

The behavioural challenges common to all three companies include the phenomenon of budgetary slack, where managers intentionally underestimate revenue potential or overestimate resource requirements to create a cushion against uncertainty. Research has consistently shown that slack creation is a rational response to performance evaluation systems that punish managers for failing to achieve targets, particularly in environments characterised by high uncertainty (Lukka, 1988). In the Nigerian context, where currency fluctuations, raw material availability, and electricity supply are highly unpredictable, the pressure to create slack may be particularly intense. Understanding how these behavioural responses manifest across different ownership structures and industrial sectors is a central concern of this study.

Another critical behavioural issue is the tendency toward dysfunctional decision-making induced by performance measurement systems. When accounting measures are used to evaluate managerial performance, individuals may focus their efforts on improving measured dimensions while neglecting unmeasured but strategically important activities. A production manager evaluated primarily on output volume may sacrifice quality; a cost centre manager evaluated on expense reduction may defer necessary maintenance; and a marketing manager evaluated on short-term sales may accept unprofitable orders. These behavioural responses are not the result of managerial irrationality but rather represent rational adaptations to the performance measurement system. The design of management accounting systems must therefore anticipate these responses and incorporate safeguards such as balanced scorecards, multiple performance dimensions, and careful attention to unintended consequences (Merchant and Van der Stede, 2017).

Participation in the budgeting process represents another behavioural dimension that varies across the three study companies based on their different organisational cultures. Research has established that participative budgeting, where managers who are responsible for achieving budget targets are involved in setting those targets, generally leads to higher budget commitment, greater information sharing, and improved performance compared to imposed budgets. However, participation can also lead to gaming behaviour, where managers use their participation to inflate resource requests or deflate revenue targets. The effectiveness of participative budgeting depends on organisational culture, trust relationships, and the consequences attached to budget achievement. The contrast between Nigerian-owned ANAMCO and Emenite versus multinational-affiliated Nigerian Breweries provides an opportunity to examine how different organisational and ownership contexts shape participative budgeting practices (Argyris, 1952).

The use of accounting information for performance evaluation raises additional behavioural concerns related to fairness, motivation, and organisational justice. When managers perceive that performance targets are unrealistic, that evaluation processes are arbitrary, or that rewards are inequitably distributed, they may respond with reduced effort, increased gaming behaviour, or withdrawal of discretionary contributions. The concept of procedural justice—the fairness of the processes by which performance evaluation decisions are made—has been shown to influence how managers respond to accounting information regardless of whether the outcomes are favourable. In the Nigerian context, where managerial labour markets are less fluid than in developed economies and where social relationships influence organisational dynamics, the behavioural effects of perceived unfairness may be particularly significant (Lindquist, 1995).

The cultural context of Nigeria introduces distinctive behavioural dimensions that are not adequately captured in management accounting theories developed primarily in Western settings. Hofstede’s cultural dimensions framework identifies Nigeria as a society with relatively high power distance (acceptance of hierarchical authority), high collectivism (emphasis on group loyalty over individual achievement), and relatively high uncertainty avoidance (preference for structured situations and clear rules). These cultural values influence how managers and employees respond to accounting controls. High power distance may lead subordinates to accept performance targets without questioning their feasibility, reducing the informational benefits of participative budgeting. Collectivism may create tensions between individual performance measures and group-oriented work arrangements. Uncertainty avoidance may increase demand for detailed rules and procedures, potentially at the expense of managerial discretion and initiative (Hofstede, 1984; Agbejule, 2011).

The institutional environment of Nigerian business, including regulatory frameworks, infrastructure quality, and market structures, also shapes behavioural responses to management accounting systems. The Central Bank of Nigeria’s monetary policies, foreign exchange regulations, and banking sector governance directly affect how companies plan, budget, and evaluate performance. Unpredictable electricity supply, transportation infrastructure challenges, and raw material import complexities create uncertainty that managers cannot control but for which they are held accountable. In such environments, the behavioural tendency toward creating budgetary slack may be not merely understandable but rational and value-preserving. Management accounting systems that do not accommodate this environmental uncertainty may induce dysfunctional behaviour rather than align managerial actions with organisational objectives (Udoayang and Udeh, 2015).

The Nigerian Companies and Allied Matters Act, the Financial Reporting Council of Nigeria regulations, and listing requirements for companies traded on the Nigerian Exchange Group establish the formal framework within which management accounting systems operate. However, the behavioural aspects of management accounting are shaped not only by formal regulations but by informal norms, professional networks, and industry practices. The role of the Institute of Chartered Accountants of Nigeria (ICAN) in shaping management accounting education and practice, the influence of expatriate managers in transferring practices from multinational parents, and the effects of international financial institution conditionalities on state-influenced enterprises like ANAMCO all contribute to the behavioural dynamics observed in Nigerian companies (Okike, 2004).

The performance management challenges facing Nigerian manufacturing companies have intensified in recent decades due to increased import competition, trade liberalisation policies, and the relative decline of domestic manufacturing in favour of services and extractive industries. Companies like ANAMCO have faced severe competitive pressures from used imports and new vehicle imports, while Emenite competes with imported building materials and informal sector producers. Nigerian Breweries, benefiting from high transport costs that create natural protection for locally brewed products, has remained profitable but faces challenges from changing consumer preferences, excise tax policies, and raw material import costs. In this challenging environment, effective management accounting systems that motivate appropriate behaviour and inform sound decisions are not merely desirable but essential for organisational survival (Adebayo and Adebiyi, 2019).

The behavioural aspect of management accounting has received increased attention from Nigerian accounting scholars in recent years, but significant gaps remain in the empirical literature. Studies have examined budgeting practices, performance measurement, and cost management in Nigerian companies, but relatively few have focused specifically on the behavioural responses to these systems. Moreover, most studies have been cross-sectional surveys that provide snapshots of practices rather than longitudinal or comparative case studies that reveal the dynamics of behaviour within specific organisational contexts. This study addresses these gaps by providing an in-depth comparative analysis of three manufacturing companies in Enugu, examining how managers and employees at different organisational levels perceive, respond to, and sometimes subvert management accounting information and controls (Akenbor and Oghoghomeh, 2013).

1.2 Statement of Problems

Despite the widespread adoption of formal management accounting systems in Nigerian manufacturing companies, persistent evidence suggests that these systems are not achieving their intended behavioural objectives of motivating desired managerial actions, informing sound decision-making, and aligning individual behaviour with organisational goals. The problem is not that Nigerian companies lack management accounting systems—budgets, standard costing, variance analysis, and performance metrics are commonly used. Rather, the problem is that these systems produce behavioural consequences that are often unintended and frequently dysfunctional, undermining rather than supporting organisational effectiveness. This disconnect between the technical design of management accounting systems and their actual behavioural consequences in practice constitutes the central problem addressed by this study.

The first critical problem concerns the prevalence of budgetary slack creation across Nigerian manufacturing companies. Managers responsible for achieving budget targets have incentives to negotiate targets that are achievable, which leads them to underestimate revenue potential and overestimate resource requirements. While slack creation is a universal phenomenon documented in management accounting research worldwide, the Nigerian context intensifies this tendency due to extreme environmental uncertainty. Currency fluctuations can change input costs overnight; electricity supply interruptions can halt production unpredictably; and policy changes can alter competitive conditions without warning. In this environment, the gap between budgeted and actual performance reflects not only managerial competence but also factors entirely beyond managerial control. The problem is that traditional management accounting systems treat all variances as equally diagnostic, failing to distinguish between performance deficiencies that reflect managerial effort and those that reflect environmental factors, thereby encouraging further slack creation as managers protect themselves against uncontrollable risks.

The second problem relates to the dysfunctional decision-making induced by performance measurement systems in the three study companies. At Emenite Nigeria PLC, for example, production supervisors evaluated primarily on output volume may sacrifice quality maintenance to achieve production targets, leading to higher defect rates and customer complaints. At ANAMCO, managers evaluated on cost reduction may defer necessary maintenance or training, saving money in the short term but impairing productive capacity over time. At Nigerian Breweries Enugu, the tension between locally relevant performance measures and group-level reporting requirements may lead to gaming behaviour where local managers present information in ways that satisfy headquarters reporting requirements while obscuring local operational realities. These behavioural responses are not the result of poor managerial character but rather represent predictable responses to the design of performance measurement systems that fail to anticipate and safeguard against unintended consequences.

The third problem concerns the effectiveness of participative budgeting processes across different organisational and ownership contexts. Research has established that participation in budget-setting generally increases budget commitment and performance when certain conditions are met: when participants have relevant information, when the organisational culture supports open dialogue, and when there is trust between superiors and subordinates. In the Nigerian context, however, these conditions are not uniformly present. At ANAMCO, the history of government ownership and bureaucratic decision-making may have created a culture where budget participation is ceremonial rather than substantive. At Emenite, the competitive pressures of the building materials market may lead to budget targets being imposed from senior management with limited participation from operational managers. At Nigerian Breweries, participation may be more extensive but shaped by the requirements of group-level reporting cycles that may not align with local operational realities. The problem is that management accounting theory does not provide clear guidance on how to design participative processes that are effective in the Nigerian context.

The fourth problem concerns the interaction between cultural values and management accounting controls. Nigerian cultural characteristics—including high power distance, collectivism, and particularism (the tendency to treat situations based on relationships rather than abstract rules)—may systematically affect how managers and employees respond to accounting information. High power distance may mean that subordinates accept unrealistic budget targets without question, reducing the informational benefits that participative budgeting is supposed to generate. Collectivism may create tension between individual performance measures and the group-oriented norms that characterise many Nigerian workplaces. Particularism may mean that formal accounting controls are overridden by personal relationships and obligations in ways that undermine system integrity. The problem is that management accounting systems designed in Western individualist, low-power-distance cultural contexts have been adopted in Nigeria without adequate adaptation to local cultural conditions, leading to behavioural responses that differ systematically from those predicted by theory.

The fifth problem concerns the role of management accounting information in performance evaluation and the behavioural consequences of perceived procedural injustice. When managers perceive that performance evaluation processes are arbitrary, that targets are politically determined rather than rationally derived, or that rewards are inequitably distributed, they may respond with reduced effort, increased resistance, or withdrawal from discretionary activities. The problem is particularly acute in Nigerian companies where managerial labour markets are relatively underdeveloped, meaning that dissatisfied managers cannot easily move to other employers. In such contexts, the behavioural responses to perceived unfairness may take passive forms—reduced initiative, withholding of information, compliance without commitment—that are difficult to detect but cumulatively damaging to organisational performance. The research problem is to understand how management accounting systems can be designed to be perceived as procedurally just in the Nigerian context.

1.3 Aim of the Study

The specific aim of this research work is to critically examine the behavioural aspects of management accounting in selected Nigerian manufacturing companies—ANAMCO, Emenite Nigeria PLC Enugu, and Nigerian Breweries PLC Enugu—with a particular focus on understanding how management accounting systems influence managerial and employee behaviour, how behavioural responses vary across different organisational and ownership contexts, and how management accounting systems can be designed to motivate productive behaviour while minimising dysfunctional consequences.

1.7 Justification of the Study

This study is justified by the persistent gap between the technical sophistication of management accounting systems adopted by Nigerian manufacturing companies and their actual effectiveness in shaping productive managerial behaviour. Despite decades of management accounting education, professional training, and system implementation, Nigerian companies continue to experience dysfunctional behavioural consequences including budgetary gaming, decision-making myopia, and employee resistance to accounting controls. These problems impose real economic costs in terms of suboptimal resource allocation, reduced organisational flexibility, and impaired competitive performance. By focusing specifically on the behavioural dimension of management accounting—the aspect most directly linked to managerial motivation and decision quality—this study addresses a critical gap in the Nigerian accounting literature, which has historically emphasised technical and procedural aspects of accounting while neglecting the behavioural dynamics that ultimately determine whether accounting systems achieve their intended purposes.

Furthermore, the study is justified by the comparative case study methodology that enables examination of how behavioural responses differ across ownership structures, industrial sectors, and organisational histories. ANAMCO’s state-influenced heritage, Emenite’s Nigerian-owned competitive positioning, and Nigerian Breweries’ multinational affiliation provide a natural experiment for understanding how contextual factors moderate the behavioural effects of management accounting systems. This comparative design generates insights that single-company or broad-survey studies cannot provide, revealing not only what behavioural patterns exist but why they differ across contexts. The selection of Enugu as the study location is further justified by the presence of these three established manufacturing companies within the same geographic area, enabling consistent data collection while capturing substantial variation in organisational characteristics.

1.8 Significance of the Study

This study makes significant contributions to multiple stakeholder groups with interests in Nigerian manufacturing performance and management accounting practice. For management accountants and financial professionals in Nigerian companies, the study provides evidence-based insights into how different management accounting system designs produce different behavioural consequences, enabling more informed choices about budget process design, performance measurement approaches, and control system implementation. For senior executives and board members, the study illuminates how seemingly technical accounting choices have profound behavioural implications that affect managerial motivation, decision quality, and organisational culture. For academic researchers, the study contributes to the empirical literature on behavioural management accounting in emerging economy contexts, testing and extending theories developed primarily in Western settings against Nigerian evidence. For policymakers and professional bodies including the Institute of Chartered Accountants of Nigeria, the study provides evidence to inform continuing professional education, curriculum development, and practice guidance in behavioural aspects of management accounting. For the three study companies themselves—ANAMCO, Emenite Nigeria PLC Enugu, and Nigerian Breweries PLC Enugu—the study offers diagnostic insights into their current management accounting practices and recommendations for improvement.

1.9 Scope of the Study

The scope of this study is delimited to an examination of the behavioural aspects of management accounting in three manufacturing companies located in Enugu State, Nigeria: ANAMCO (Anambra Motor Manufacturing Company), Emenite Nigeria PLC Enugu, and Nigerian Breweries PLC Enugu. The study focuses specifically on behavioural dimensions including budgetary slack, participative budgeting, performance measurement consequences, the influence of cultural values, and procedural justice in performance evaluation. The study does not examine technical aspects of management accounting including cost allocation methodologies, inventory valuation, transfer pricing, or capital budgeting techniques except insofar as these technical features have behavioural implications. The study is limited to manufacturing companies and does not examine service sector, extractive industry, or financial services organisations whose management accounting contexts may differ substantially. The study is geographically limited to Enugu State and does not claim to represent management accounting practices in other Nigerian states or regions, although findings may have broader applicability. The study focuses on managerial and supervisory employees who interact with management accounting systems and does not include entry-level production workers whose behavioural responses to accounting information may be qualitatively different.

CHAPTER TWO: LITERATURE REVIEW

2.1 Theoretical Review

The theoretical foundation for examining the behavioural aspects of management accounting in Nigerian manufacturing companies draws from multiple theoretical perspectives that explain how and why individuals respond to accounting information, budgets, and performance measures. This section critically reviews the principal theories that inform understanding of behavioural management accounting, including agency theory, contingency theory, goal-setting theory, expectancy theory, and cultural theory.

2.1.1 Agency Theory

Agency theory, as developed by Jensen and Meckling (1976), provides a foundational framework for understanding behavioural aspects of management accounting by conceptualising the relationship between principals (owners or shareholders) and agents (managers) as one characterised by information asymmetry and diverging interests. In the corporate context, managers (agents) possess superior information about their own actions, effort levels, and the business environment compared to owners (principals), creating opportunities for opportunistic behaviour. Management accounting systems are designed partially to reduce this information asymmetry by providing principals with information about agent performance, thereby enabling monitoring and incentive alignment. The behavioural implications are profound: management accounting information is not neutral but rather shapes the strategic interaction between principals and agents (Eisenhardt, 1989).

From an agency theory perspective, the behavioural problems in management accounting—including budgetary slack, short-term decision-making, and gaming of performance measures—are predictable responses to the incentive structures embedded in accounting systems. When managers are evaluated and compensated based on achieving budget targets, they have rational incentives to negotiate targets that are easily achievable (slack creation) and to focus effort on measured dimensions while neglecting unmeasured but important activities (dysfunctional behaviour). Agency theory predicts that these behavioural responses can be mitigated through improved monitoring (audits, reviews), incentive alignment (performance-based compensation), and bonding mechanisms (reputation, career concerns), but never fully eliminated because information asymmetry can never be completely resolved (Baiman, 1990).

The application of agency theory to the Nigerian context requires attention to distinctive institutional features that affect principal-agent relationships. In state-influenced enterprises like ANAMCO, the principal-agent relationship is complicated by multiple principals (government shareholders, private partner Daimler) with potentially conflicting objectives. The presence of government ownership may weaken monitoring intensity compared to private ownership, as government representatives may lack financial incentives or sectoral expertise to monitor managerial behaviour effectively. In family-owned or closely held companies like Emenite, principal-agent relationships may be more direct, with owners actively involved in management, reducing information asymmetry but potentially introducing other behavioural dynamics related to family relationships and succession. In multinational subsidiaries like Nigerian Breweries, agency relationships operate across multiple levels—local managers accountable to country management, country management accountable to regional headquarters, and regional headquarters accountable to global parent—creating layered information asymmetry and monitoring challenges (Uche, 2008).

The agency theory framework also explains the demand for participative budgeting and its behavioural consequences. Participation in budget-setting can serve as an information transfer mechanism through which agents reveal private information about environmental conditions and operational constraints, reducing information asymmetry. However, participation also creates opportunities for strategic misrepresentation, as managers may use their participation to inflate resource requests or deflate revenue projections. The net effect of participation on organisational performance depends on whether the information-revealing benefits outweigh the gaming costs, which in turn depends on organisational culture, trust relationships, and the consequences attached to budget achievement. In Nigerian manufacturing companies, where environmental uncertainty is high and trust between hierarchical levels may be limited, the balance between benefits and costs of participation may differ systematically from patterns observed in developed economies (Locke and Latham, 1990).

2.1.2 Contingency Theory

Contingency theory, developed by Lawrence and Lorsch (1967) and subsequently applied to management accounting by Otley (1980) and others, argues that there is no universally optimal management accounting system design. Rather, the effectiveness of management accounting practices depends on the fit between system characteristics and the contingencies facing the organisation, including environmental uncertainty, technology, strategy, size, and organisational culture. The behavioural implications of contingency theory are that the same management accounting practice—for example, tight budget controls or participative budgeting—may produce different behavioural responses and performance outcomes depending on the contingency factors present in the organisation. This perspective is particularly relevant for the Nigerian context, where contingency factors may differ systematically from those in the developed economies where most management accounting research has been conducted (Chenhall, 2003).

Environmental uncertainty is a critical contingency factor affecting behavioural responses to management accounting systems. When uncertainty is high—as in Nigerian manufacturing due to currency fluctuations, electricity supply interruptions, and policy volatility—traditional management accounting controls that emphasise fixed targets and tight variance analysis may induce dysfunctional behavioural responses including defensive slack creation, blame avoidance, and reduced risk-taking. In such environments, contingency theory suggests that more flexible control systems, emphasising adaptive planning, rolling forecasts, and relative performance evaluation, may produce more constructive behavioural responses. The implication for Nigerian companies is that adopting management accounting practices developed in stable developed economies without adaptation to local uncertainty levels may be counterproductive (Chapman, 1997).

Technology and task characteristics represent additional contingency factors influencing behavioural responses to management accounting. Manufacturing companies like ANAMCO (assembly operations), Emenite (continuous process manufacturing), and Nigerian Breweries (batch processing) face different production technologies that create different requirements for performance measurement and control. Assembly operations with measurable output per worker may support individual performance measures, while continuous process manufacturing may require team-based measures. The behavioural responses to management accounting systems—including acceptance of targets, perceived fairness of evaluation, and effort allocation—depend on the alignment between measurement system design and task characteristics. Misfit between measurement approach and task technology is a significant source of dysfunctional behaviour (Hayes, 1977).

Organisational size and structure also moderate the behavioural effects of management accounting systems. Larger organisations like Nigerian Breweries (as part of multinational Heineken) typically have more formalised management accounting systems, greater role specialisation, and more hierarchical performance evaluation structures compared to smaller organisations like Emenite. Behavioural responses to formal controls differ by size: in larger organisations, managers may accept formal controls as legitimate expressions of organisational authority, while in smaller organisations, formal controls may be perceived as intrusive and undermining of professional autonomy. The contingency perspective suggests that effective management accounting system design must consider these size-related differences in behavioural expectations and responses (Merchant, 1981).

2.1.3 Goal-Setting Theory

Goal-setting theory, developed by Locke (1968) and extensively refined by Locke and Latham (1990, 2002), provides a psychological framework for understanding how performance targets influence motivation and behaviour. The theory posits that specific, challenging goals lead to higher performance than easy goals, vague goals, or no goals, provided that individuals have the necessary ability and receive feedback on progress. Goals affect performance through four mechanisms: they direct attention toward goal-relevant activities, mobilise effort, increase persistence, and motivate the development of task-relevant strategies. The behavioural implications for management accounting are direct: the budget targets that are central to management accounting systems are, in essence, organisational goals that should be designed according to goal-setting principles to maximise motivational effects (Locke and Latham, 2002).

The goal-setting framework has significant implications for understanding budgetary behaviour in Nigerian manufacturing companies. The theory predicts that budget targets that are perceived as attainable but challenging will generate the highest performance, while targets perceived as impossible will lead to reduced effort and disengagement. In the Nigerian context, where environmental uncertainty creates unpredictable shocks that affect performance, the distinction between challenging but attainable and impossible targets becomes critical. Managers who experience targets that become impossible due to external factors (currency devaluation, electricity cuts) may disengage from the budgeting process entirely, reducing the motivational benefits of goal-setting. The behavioural response is not irrational but reflects the rational recognition that effort will not translate into target achievement under extreme conditions (Latham, 2004).

Goal commitment—the degree to which an individual is determined to pursue a goal—is a critical moderator of goal-setting effects that has received substantial attention in behavioural management accounting research. Factors affecting goal commitment include the perceived importance of goal achievement, self-efficacy (belief in one’s ability to achieve the goal), and the publicness of goal commitment. Participative budgeting can enhance goal commitment when participation increases perceived ownership of targets and when participants believe the process is fair. However, participation without genuine influence—ceremonial participation—may actually reduce commitment. The implication for Nigerian companies is that the behavioural benefits of participative budgeting depend on the authenticity of participation and the credibility of the goal-setting process, not merely on the procedural form (Erez and Kanfer, 1983).

Feedback is the final element of goal-setting theory with direct relevance to management accounting. Feedback on progress toward goals enables individuals to adjust effort, refine strategies, and maintain motivation. In management accounting systems, variance analysis provides this feedback function, comparing actual performance against budgeted targets. However, the behavioural effects of feedback depend on its timing, specificity, and perceived credibility. Feedback that is delayed, aggregated, or perceived as manipulated may have no motivational effect or may even reduce performance. In the Nigerian context, where accounting information timeliness is challenged by infrastructure constraints and reporting delays, the feedback function of variance analysis may be impaired, reducing the motivational benefits of goal-setting (Kluger and DeNisi, 1996).

2.1.4 Expectancy Theory

Expectancy theory, developed by Vroom (1964) and extended by Porter and Lawler (1968), provides a motivational framework for understanding how individuals make choices among alternative behavioural options based on their expectations about outcomes. The theory posits that motivation is a function of three beliefs: expectancy (the belief that effort will lead to performance), instrumentality (the belief that performance will lead to rewards), and valence (the value the individual places on the expected rewards). Individuals choose the behavioural option that maximises the product of expectancy, instrumentality, and valence across available alternatives. The behavioural implications for management accounting are that performance measurement and reward systems shape behaviour by influencing expectancy and instrumentality beliefs (Lawler, 1973).

In the management accounting context, expectancy theory explains why managers might engage in budgetary slack creation, short-term decision-making, or gaming of performance measures. If the reward system emphasises achieving budget targets (high instrumentality), but the manager believes that effort alone cannot guarantee target achievement due to environmental uncertainty (low expectancy), then the rational response is to seek ways to increase expectancy—for example, by negotiating easier targets (slack creation) or by focusing effort on controllable dimensions while ignoring uncontrollable factors (gaming). The theory suggests that dysfunctional behaviour arises not from managerial moral failure but from the structure of expectancies and instrumentalities embedded in management accounting systems (Bonner and Sprinkle, 2002).

The three study companies likely exhibit different expectancy structures based on their ownership contexts and environmental exposures. At Nigerian Breweries, with multinational parent support and more stable operational environments, managers may have higher expectancy that effort leads to performance, reducing the incentive for slack creation. At Emenite, operating in a competitive commodity market with volatile input prices, managers may have lower expectancy, increasing the motivational appeal of slack creation as a risk management strategy. At ANAMCO, the legacy of government ownership may have created expectancy beliefs shaped by bureaucratic rather than market-based reward systems, producing different behavioural patterns. The application of expectancy theory to the Nigerian context requires attention to how local labour markets, reward practices, and employment security shape instrumentality beliefs (Akinbowale and Lourens, 2019).

The implications of expectancy theory for management accounting system design are that reward systems must be carefully aligned with the controllability principle: managers should be evaluated and rewarded only for performance dimensions they can influence. When uncontrollable environmental factors affect performance, expectancy beliefs are weakened, reducing motivation. This suggests that Nigerian companies should incorporate mechanisms for filtering out uncontrollable variances—for example, through flexible budgeting that adjusts targets for exogenous factors—to maintain expectancy beliefs and reduce incentives for slack creation. The failure to implement such adjustments is a significant source of dysfunctional behaviour in high-uncertainty environments (Merchant and Van der Stede, 2017).

2.1.5 Cultural Theory

Cultural theory, as developed by Hofstede (1980, 2001) and applied to management accounting by Harrison (1992, 1993) and Chow, Kato, and Merchant (1996), provides a framework for understanding how national and organisational cultural values shape the design and behavioural consequences of management accounting systems. Hofstede’s dimensions—power distance, individualism versus collectivism, uncertainty avoidance, masculinity versus femininity, and long-term orientation—have been shown to influence preferences for budget participation, the use of accounting information in performance evaluation, and responses to tight versus loose controls. The behavioural implications are that management accounting practices that are effective in one cultural context may produce different or even negative behavioural consequences when transferred to another cultural context without adaptation (Harrison and McKinnon, 1999).

Nigeria’s cultural profile on Hofstede’s dimensions has important implications for management accounting behaviour. Nigeria scores relatively high on power distance, meaning that subordinates expect hierarchical authority and may be reluctant to challenge superiors or provide upward feedback. In the budgeting context, high power distance may mean that participative budgeting processes are less effective because subordinates do not feel empowered to negotiate targets or reveal private information to superiors. Budget targets may be accepted passively even when they are unrealistic, and variance explanations may avoid upward attribution of problems. The behavioural implication is that Nigerian companies cannot simply adopt participative budgeting practices developed in low-power-distance cultures and expect the same beneficial effects on motivation and information sharing (Agbejule, 2011).

Nigeria also scores relatively high on collectivism, meaning that individuals prioritise group loyalty and relationships over individual achievement and autonomy. In management accounting contexts, collectivism suggests that individual performance measures may be less motivating and may even create dysfunctional conflict within work groups. Team-based performance measures and group rewards may be more culturally congruent and may generate more positive behavioural responses. Nigerian companies that have adopted individual performance measurement systems from individualistic Western cultures may be experiencing unintended negative consequences including reduced cooperation, information hoarding, and intra-group competition that undermines collective effectiveness (Uddin and Hopper, 2003).

Uncertainty avoidance—the extent to which individuals feel threatened by ambiguous or unknown situations—is another culturally variable dimension with management accounting implications. Nigeria scores moderately on uncertainty avoidance, suggesting that managers may prefer clear rules, formal procedures, and predictable performance expectations. However, the high environmental uncertainty characterising Nigerian business creates a tension between cultural preference for certainty and environmental reality of unpredictability. Management accounting systems that provide clear targets and stable benchmarks may satisfy cultural preferences but may induce dysfunctional behaviour when those targets become obsolete due to environmental shocks. Flexible, adaptive control systems may be culturally uncomfortable but functionally necessary in the Nigerian context (Chow, Kato, and Merchant, 1996).

2.2 Conceptual Framework

The conceptual framework for this study specifies the relationship between independent variables representing management accounting system characteristics and dependent variables representing behavioural outcomes in Nigerian manufacturing companies. The framework also identifies moderating variables that influence the strength of these relationships and contextual variables that must be accounted for in analysis.

2.2.1 Independent Variables

The independent variables in this study are characteristics of management accounting systems that are theoretically expected to influence managerial and employee behaviour. The first independent variable is budget target characteristics, including target difficulty (easy versus challenging), target specificity (vague versus specific), and target source (participatively set versus imposed). Based on goal-setting theory, specific and challenging targets are expected to generate higher performance than vague or easy targets, but only when individuals have accepted the targets and receive feedback. The relationship between target characteristics and behavioural outcomes is moderated by cultural values, environmental uncertainty, and individual differences in goal commitment (Locke and Latham, 2002).

The second independent variable is performance measurement system design, including the dimensions measured (financial only versus balanced scorecard), the specificity of measures, and the linkage between measured performance and rewards. Based on agency theory and expectancy theory, performance measurement systems that align with controllability principles (measuring only dimensions managers can influence) and that provide clear instrumentality (performance leads to meaningful rewards) are expected to generate more constructive behavioural responses, while systems that violate controllability or have weak instrumentality may induce slack creation and gaming behaviour (Merchant and Van der Stede, 2017).

The third independent variable is the degree of budget participation, defined as the extent to which managers who are responsible for achieving budget targets are involved in setting those targets. Based on participative budgeting research, participation is expected to increase budget commitment, information sharing, and performance when certain conditions are met: when participation is authentic (genuinely influences targets), when organisational culture supports open dialogue, and when trust exists between hierarchical levels. However, participation may also increase gaming behaviour when managers use participation strategically to create slack. The net effect is contingent on contextual factors including power distance and environmental uncertainty (Argyris, 1952; Shields and Shields, 1998).

The fourth independent variable is feedback characteristics, including the timeliness of performance feedback, the specificity of variance analysis, and the perceived credibility of accounting information. Based on goal-setting theory, feedback is essential for maintaining motivation and enabling performance improvement, but feedback effects depend on how feedback is delivered (constructive versus critical) and whether feedback identifies actionable improvement opportunities. In Nigerian manufacturing companies, infrastructure constraints affecting accounting information timeliness may compromise feedback effectiveness (Kluger and DeNisi, 1996).

2.2.2 Dependent Variables

The dependent variables in this study represent behavioural outcomes of management accounting system operation. The first dependent variable is budgetary slack creation, defined as the intentional understatement of revenue potential or overstatement of resource requirements by managers during the budgeting process. Slack can be measured through self-reported slack creation, through comparisons of budgeted versus actual performance, and through qualitative assessment of budgeting practices. While some slack may be functional (providing a buffer against uncertainty), excessive slack represents a misallocation of organisational resources and a failure of management control systems (Lukka, 1988).

The second dependent variable is dysfunctional decision-making, defined as managerial actions that are induced by performance measurement systems but that work against organisational objectives. Dysfunctional behaviours include short-termism (sacrificing long-term value for short-term measured performance), quality sacrifice (reducing quality to meet cost or volume targets), and gaming (manipulating accounting or operational measures without improving underlying performance). These behaviours are measured through manager self-reports, through examination of decision outcomes, and through qualitative analysis of specific decisions (Hopwood, 1972).

The third dependent variable is budget commitment, defined as the degree to which managers feel personally responsible for achieving budget targets and are determined to exert effort toward goal attainment. Budget commitment is distinct from mere budget acceptance (agreeing to targets without personal investment) and is a critical mediating variable between budget characteristics and performance outcomes. Commitment is measured through validated psychological scales assessing goal acceptance, determination to achieve targets, and persistence in the face of difficulty (Erez and Kanfer, 1983).

The fourth dependent variable is managerial effort, defined as the intensity and persistence of work behaviour directed toward organisational objectives. Effort is distinguished from performance (which also depends on ability and environmental factors) and is a direct measure of motivation. Effort is measured through manager self-reports, through supervisor ratings, and where possible through observable indicators of work intensity and time allocation (Bonner and Sprinkle, 2002).

The fifth dependent variable is procedural justice perception, defined as the degree to which managers perceive that performance evaluation processes are fair, consistent, accurate, and ethical. Procedural justice is both a dependent variable (influenced by management accounting system design) and an independent variable (influencing other behavioural outcomes). Perceived procedural justice is measured through validated scales assessing the fairness of performance evaluation procedures (Lindquist, 1995).
