Sticky Costs, Elastic Cost Structures and Allocations That Change Behavior: What Recent Research Means for Cost Management

Introduction

Cost accounting textbooks build their models on a convenient assumption: within the relevant range, variable costs move in proportion to activity and fixed costs do not move at all. Lanen et al. (2017) present cost-volume-profit analysis, flexible budgets and cost estimation on this foundation, and for planning purposes it works well. Yet managers decide how much of their cost base to commit in advance, how quickly to cut resources when demand falls and how to charge shared costs to the units that use them. Those decisions mean that cost behavior is not simply a technical property of an organization; it is partly a choice. This paper reviews recent accounting research on that choice and argues that cost behavior is shaped by governance, by creditors and suppliers and by the cost allocation methods managers live under, with direct implications for budgeting and performance evaluation. The review draws on seven articles from the Journal of Management Accounting Research published between 2023 and 2025, chosen because each tests a part of the textbook's cost behavior model with recent data or experiments. The paper first summarizes the classic evidence on sticky costs, then groups the recent studies into three themes, and finally applies the findings to estimation, budgeting, performance evaluation and a composite manufacturer.

From Symmetric Costs to Sticky Costs

The research tradition begins with Anderson et al. (2003), who studied more than 7,600 firms over twenty years and reported an asymmetry: a 1% rise in sales was met, on average, by a 0.55% rise in selling, general and administrative costs, while a 1% fall brought a decline of only 0.35%. Costs, in other words, were sticky: managers added resources when activity rose but did not shed them as quickly when it fell. Some stickiness is economically sensible, since cutting capacity and rehiring later is costly, but some may reflect managers' reluctance to shrink the resources under their control. That distinction, between efficient and agency-driven stickiness, runs through the recent literature. It matters for practice because the two kinds call for different responses. Efficient stickiness, such as keeping skilled machinists through a short downturn, protects capacity the firm will need; agency-driven stickiness, such as preserving a division's headcount to protect a manager's standing, simply wastes resources. A controller who can tell the two apart can advise management on which costs to defend and which to cut.

Who Restrains Sticky Costs?

Two recent studies identify parties that reduce agency-driven stickiness. Zhang et al. (2023) examined internal governance, the monitoring of the chief executive by key subordinates within the top management team, and found that cost stickiness was lower where internal governance was stronger, after controlling for economic reasons to retain resources. The effect was stronger where selling, general and administrative spending created less future value and where board monitoring was more effective, both consistent with internal governance curbing resources kept for managers' own benefit. Zhou (2024) used debt covenant violations as a natural experiment, since a violation transfers control rights to creditors, and found with a regression discontinuity design that stickiness declined sharply after violations. The decline was larger for borrowers with lower credit ratings, when creditors had more bargaining power and during industry downturns. Taken together, the two studies suggest that sticky costs are partly a governance problem, and that whoever gains the power to question spending can make costs less sticky.

Choosing How Elastic Costs Should Be

A second group of studies looks at cost structure itself, the mix of fixed and variable commitments. Chen et al. (2023) hand-collected supplier information for 4,530 firm-year observations of Chinese listed companies and found that firms with more concentrated supplier bases chose more elastic cost structures, consistent with managers buying flexibility to offset supply risk. Pizzini and Vansant (2024), working with data on over 2,000 American hospitals, found that hospitals with monopsony power, the market position of a dominant buyer, adopted more elastic cost structures, and that monopsony power strengthened the link between demand uncertainty and cost elasticity documented in earlier research. Their explanation is that purchasing power lowers the cost of buying resources on flexible, short-term terms. Fang et al. (2023) found that after credit default swaps began trading on a firm's debt, the firm's cost structure became more elastic, with larger effects for firms with greater credit risk, more restrictive covenants or tighter financial constraints. All three studies show that cost structure responds to the risks and bargaining positions a firm faces, which is exactly the managerial choice the textbook's fixed and variable categories take as given. The three studies also point to a common mechanism. In each case, flexibility has value because something outside the firm's control, a supplier's reliability, the volume of patients, the willingness of lenders to renegotiate, makes long-term commitments riskier. When that outside risk rises, managers trade some efficiency for the ability to cut costs quickly, which is the same logic a student meets in the textbook's discussion of how a high fixed-cost share magnifies swings in profit, now observed in real firms' choices.

Allocations That Change Behavior

A third group concerns cost allocation, the subject of the course's later chapters. Brown et al. (2025) conducted two experiments comparing insulating allocations, which charge each unit independently of other units' performance, with noninsulating allocations, which distribute costs according to units' realized relative performance. Noninsulating allocations, by tying managers' reported results to one another, led to greater cooperation between managers and to greater risk-taking than insulating allocations. Cohen et al. (2024) studied cost-shifting, the misreporting of costs from one project or unit to another, and found in an experiment that when outcomes were framed negatively for managers, the level of cost-shifting changed little with the amount of control managers had over results, while under positively framed outcomes, the decision to shift costs depended on whether the manager had control. These findings mean that an allocation method is a control system: the same overhead charged in different ways can change how managers cooperate, how much risk they take and how honestly they report.

Implications for Cost Estimation and Budgeting

The research has direct consequences for the cost estimation methods covered in the course. Lanen et al. (2017) present account analysis, the high-low method and regression as ways to separate fixed and variable components, all of which assume that one variable rate applies whether activity rises or falls. If costs are sticky, a regression fitted to a period of growth will overstate how much cost can be saved when volume declines. A simple remedy is to estimate separate slopes for increases and decreases, or to add an indicator for periods of declining activity, which lets the data reveal whether the firm's costs behave asymmetrically. The same caution applies to flexible budgets. A flexible budget that uses a single variable rate will show unfavorable spending variances in a downturn that may reflect deliberate decisions to retain capacity rather than poor control, so variance reports should distinguish resources kept by choice from costs that simply were not managed.

The research on cost structure adds a planning question. When a company prepares its master budget, it implicitly decides how much of next year's cost will be committed in advance. The findings of Chen et al. (2023), Pizzini and Vansant (2024) and Fang et al. (2023) suggest that this decision should be revisited whenever supply, demand or credit risk changes, not inherited from the prior year. A budget committee that asks, each year, which costs could be converted to flexible arrangements and at what premium is treating cost structure as the choice the research shows it to be.

Implications for Performance Evaluation

The allocation studies speak to the course's chapters on decentralization and performance measurement. When overhead is charged to divisions, managers respond to the allocation as well as to their own operations. Brown et al. (2025) show that the choice between insulating and noninsulating allocations changes cooperation and risk-taking, and Cohen et al. (2024) show that the framing of managers' contracts affects whether they shift costs between projects. An organization that evaluates managers on allocated profit therefore needs to consider which behaviors its allocation encourages, and it should pair allocated measures with controls, such as review of transfers between cost pools, that make cost-shifting harder to hide.

Application to a Parts Manufacturer

Consider a composite manufacturer of hydraulic fittings with three plants, $240 million of revenue and a concentrated supplier base for specialty steel. Its controller uses a single plantwide overhead rate and a budget that treats most indirect labor as fixed. The research suggests three changes. Each is inexpensive and can be piloted in one plant before rollout. First, cost estimation should test for asymmetry: by regressing indirect cost changes on revenue changes separately for increases and decreases, the controller can see whether costs are sticky and present the result to the leadership team and board, the kind of scrutiny Zhang et al. (2023) associate with less stickiness. Second, given the supplier concentration, the company should consider making part of its cost structure more elastic, for example through flexible staffing agreements, as Chen et al. (2023) found firms in similar positions do. Third, the allocation of shared engineering and maintenance costs should be chosen with behavior in mind. If cooperation between plants matters, as it does when they share tooling, a noninsulating allocation may encourage it, as Brown et al. (2025) found, although the controller should watch for the greater risk-taking they also observed.

Limitations

The studies reviewed here have limits. Several rely on archival associations, which cannot fully rule out other explanations, and the supplier study uses data from one country. The allocation studies are laboratory experiments, which isolate effects cleanly but may not capture every pressure managers face in organizations. In the field, managers know one another, repeat their interactions over years and face career consequences that an experiment can only approximate, so the size of the effects could differ in practice. The archival studies, for their part, measure stickiness and elasticity from public financial statements, which aggregate many cost categories and may hide the specific decisions behind them. A controller applying the findings should therefore treat them as hypotheses to test with the company's own data rather than as rules. Still, the findings are consistent across settings in one important respect: cost behavior responds to incentives and governance in ways the textbook's categories do not show.

Conclusion

Recent accounting research turns the textbook's fixed and variable categories into a set of management choices. That change of perspective does not make the textbook's models wrong; they remain the right starting point for planning. It makes them incomplete, because they describe what costs do once commitments are made, not how those commitments come to be made. Stickiness falls when insiders or creditors have the power to question spending; cost structures become more elastic when supply, purchasing or credit conditions make flexibility valuable; and allocation methods shape cooperation, risk-taking and reporting. For cost accountants, the practical implication is that estimating, budgeting and allocating are not neutral measurements. They are part of the organization's control system, and they deserve to be designed with the same care. A controller who understands the research can explain to executives why last year's cost rates may not hold in a downturn, why a flexible staffing contract may be worth a higher hourly rate and why the method of charging shared services is as much a management decision as the services themselves.
