"New research reveals how common wage-setting practices may be hurting firms, impacting pay equity, and creating hidden economic inefficiencies."


In today's complex economic landscape, the process of determining wages is a critical yet often misunderstood aspect of business operations. While economic models assume that both firms and workers act with perfect optimization, recent research suggests a different reality. A notable trend has emerged from both survey and administrative data: wages tend to cluster around round numbers. This phenomenon, referred to as 'wage bunching', challenges traditional economic thought and hints at less-than-optimal behaviors within the market.

Wage bunching suggests some market participants are not behaving according to strict optimization principles. One explanation is that firms strategically set wages at round numbers to exploit cognitive biases in workers, such as the 'left-digit bias,' where individuals place undue emphasis on the leftmost digit of a number. However, another perspective suggests that wage bunching arises from firms engaging in simplified, or 'coarse,' wage-setting practices, potentially due to the costs and complexities of fine-tuning every salary decision.

A groundbreaking study using data from over 200 million new hires in Brazil sheds new light on this debate. The research investigates whether the tendency to set wages at round numbers is partly driven by firms' use of coarse wage-setting strategies. By analyzing worker-firm matched data, the study uncovers a series of compelling insights into the prevalence, causes, and consequences of this widespread practice, prompting a re-evaluation of how firms approach compensation and its broader economic impacts.

Wage Rules and Business Costs

Wages are the price of labor and form part of the expenses involved in running a business. U.S. Department of Labor guidance states that overtime pay must generally be at least one and one-half times the regular rate after 40 hours in a workweek, although exemptions apply. The Department's July 1, 2026 table lists the District of Columbia's minimum wage as the nation's highest at $17.50 per hour, while noting that several states schedule annual adjustments under varying formulas.

The Limits of Coarse Wage Bands

A standard wage-setting approach may group workers into broad pay grades or rely on minimum legal thresholds. Such methods can simplify administration, but they may not reflect differences in responsibilities, performance, experience, or local labor conditions. Without more granular review, a broad system may overlook where compensation is misaligned with the value and circumstances of particular roles.

How Wage Setting Evolved

Wage-setting practices have generally developed from simple, standardized rules toward systems that attempt to account for job characteristics and labor-market conditions. Legal minimums and overtime requirements established important baselines, while employers increasingly used structured pay grades and salary surveys. The historical progression suggests that wage policy has continually balanced administrative simplicity with the need for greater precision.

The Surprising Downside of 'Rounding Up': Why Coarse Wage-Setting Can Hurt Business

Illustration of wage-setting practices

The study begins by confirming a significant level of wage bunching at round numbers within the Brazilian labor market. Following this, the research explores the outcomes of firms that engage in this practice. Contrary to the expectation that firms exploiting worker biases would perform better, the study reveals a surprising trend: firms that rely on round-numbered salaries tend to experience worse market outcomes.

These 'bunching firms' exhibit several negative indicators, including poorer worker-firm matches (indicated by higher separation rates), lower job growth, and a greater likelihood of exiting the market altogether. This suggests that paying round salaries isn't a strategic move to boost profits, but rather a symptom of underlying operational inefficiencies.

  • Worse worker-firm matches: Employees hired at round-numbered salaries are more likely to leave their jobs, suggesting a mismatch between the worker's skills and the job requirements.
  • Lower job growth: Firms using coarse wage-setting strategies experience slower expansion compared to their counterparts.
  • Increased risk of market exit: Bunching firms face a higher probability of going out of business.

Evidence and Pay Precision

Recent analysis of wage-setting should distinguish between broad administrative rules and the outcomes experienced by individual workers. Useful reviews would examine whether coarse pay categories accurately reflect job demands, labor-market conditions, and differences in contribution. Because no specific studies are provided here, conclusions about the scale of any inefficiency should remain tentative.

The Case for Simplicity

Broad wage structures can reduce administrative complexity and make compensation policies easier to explain. They may also provide consistency across comparable roles, which can support predictable budgeting and implementation. Their weakness is that consistency does not necessarily mean accuracy, and a simple framework can fail when jobs or market conditions differ substantially.

Comparing Wage-Setting Models

A coarse model emphasizes uniformity and ease of administration, whereas a more differentiated model emphasizes fit between pay and the characteristics of each role. The first may be easier to manage, while the second may better capture variation in responsibilities and market conditions. A meaningful comparison would need to weigh administrative costs against the risks of underpaying, overpaying, or misclassifying workers.

To understand these findings, the study proposes that firms may use round-numbered salaries as a simplified approximation when faced with uncertainty about the optimal wage. Estimating a new worker's true value to the firm is a complex task, requiring consideration of numerous factors that are difficult to quantify. Rather than investing in precise calculations, some firms may rely on a 'rule-of-thumb' approach, leading to coarse wage-setting.

Is It Time to Rethink Your Pay Scale?

This research highlights that how wages are set matters more than we might think. As the labor market evolves, it becomes increasingly crucial for businesses to adopt wage-setting practices that are both equitable and economically sound. By moving beyond simplified approaches and embracing more nuanced methods of compensation, firms can foster stronger worker-firm relationships, drive growth, and improve their overall competitiveness. Ultimately, a more thoughtful approach to wage determination can lead to better outcomes for businesses and their employees alike.

Balancing Consistency and Precision

The central challenge in wage-setting is finding a workable balance between consistency and precision. Broad rules can establish a clear foundation, but they may leave money on the table when compensation does not track meaningful differences among roles. Any expert assessment should therefore consider both the operational value of simplicity and the financial consequences of insufficient differentiation.

Toward More Adaptive Pay Systems

Future wage-setting systems may place greater emphasis on regularly updated data, clearer role definitions, and more responsive pay ranges. Such approaches could help employers adjust compensation as labor markets and job requirements change. Their effectiveness will depend on whether organizations can improve precision without creating unnecessary administrative burdens.

Wages Within a Larger System

Wage-setting operates within a broader system shaped by regulation, business costs, labor-market conditions, and organizational policy. Legal minimums and overtime rules provide boundaries, but they do not determine whether an employer's internal pay structure is economically efficient. Systemic challenges arise when standardized policies are applied to workforces with substantially different roles, locations, or needs.

How Pay Structures Affect People

Compensation decisions affect more than payroll totals: they can influence how workers perceive fairness, recognition, and opportunity. A coarse structure may treat materially different contributions as equivalent, while overly complex systems may be difficult for employees to understand. The practical impact therefore depends on whether workers view the system as consistent, explainable, and responsive to the work they actually perform.

What coarse wage-setting adds to the picture

The evidence links coarse wage-setting to some of the wage rounding observed in the data, rather than establishing that it explains every round-number salary. In this account, a firm uses a round-number salary when it skips the cost of optimizing the wage for a worker.[1] [2]

This mechanism matters for interpreting estimates built from firms’ optimality conditions: coarse wage-setting may make those estimates biased, but the evidence does not specify the direction or size of that risk.[3]

How wage-bunching explanations compare

In a different labor-market setting, firm-specific productivity evidence finds that a higher value-added per worker is associated with a smaller wage increase. That relationship concerns productivity and wages, not the mechanism producing round-number salaries.[4]

The observational-data discussion distinguishes broad labor-market coverage from direct estimates of the economic parameters of interest. That distinction helps locate wage-bunching evidence: observing patterns in labor-market data does not by itself identify every parameter behind them.[5]

What evidence could clarify wage rounding

  • How much of observed wage rounding is attributable to coarse wage-setting rather than other processes? The evidence describes coarse setting as a partial explanation, not a complete account.[1] [2]
  • How large and in what direction is the potential bias when researchers infer parameters from firms’ optimality conditions? The stated concern identifies a risk but does not quantify it.[3]

Everything You Need To Know

1

What is 'wage bunching,' and what does it suggest about how companies determine employee pay?

Wage bunching is the phenomenon where wages tend to cluster around round numbers. This suggests that some firms may not be behaving according to strict optimization principles when setting salaries. Instead of fine-tuning every salary decision based on a worker's specific value, firms might be engaging in simplified, or 'coarse,' wage-setting practices. While not explicitly mentioned, this could also imply a lack of investment in sophisticated HR technologies or analytics that could facilitate more precise wage determination. The research indicates that firms may be using round-number salaries as a simplified approximation, but it is not necessarily driven by an attempt to exploit cognitive biases.

2

How does 'coarse wage-setting' affect a company's performance and the worker-firm match?

Coarse wage-setting, where firms use round-numbered salaries as a simplified approximation, is associated with worse market outcomes for companies. 'Bunching firms' experience poorer worker-firm matches, which are indicated by higher separation rates, lower job growth, and an increased risk of market exit. This suggests that employees hired at round-numbered salaries are more likely to leave their jobs due to a mismatch between their skills and the job requirements. The practice of coarse wage-setting doesn't improve outcomes but indicates underlying operational inefficiencies.

3

What are the potential economic consequences of firms engaging in coarse wage-setting practices?

The economic consequences of firms engaging in coarse wage-setting are far-reaching. It challenges the traditional economic assumption that firms act with perfect optimization. When firms use 'rule-of-thumb' approaches instead of investing in precise calculations to determine a worker's value, it leads to inefficiencies such as poorer worker-firm matches, lower job growth, and increased risk of market exit for these firms. This can create broader distortions in the labor market, hindering overall productivity and economic growth, and potentially impacting pay equity, though this is not explicitly detailed.

The study mentioned data from Brazil. Are the findings about 'coarse wage-setting' and 'wage bunching' likely to be applicable in other countries, or are they specific to the Brazilian labor market?

While the study uses data from the Brazilian labor market, the underlying principles of 'coarse wage-setting' and 'wage bunching' are likely applicable to other countries. Human cognitive biases, such as the 'left-digit bias,' are universal, and the complexities and costs associated with fine-tuning every salary decision exist in most economies. The extent of 'wage bunching' may vary based on cultural norms, labor laws, and industry practices, but the fundamental concept that firms sometimes simplify wage decisions for various reasons is likely widespread. Further research in different countries would be needed to confirm the extent and specific implications in those contexts.

5

In what ways might companies move beyond 'coarse wage-setting' to create more equitable and economically sound compensation strategies?

Companies can move beyond 'coarse wage-setting' by embracing more nuanced methods of compensation. This involves investing in more precise calculations to determine a worker's value, considering numerous factors that are difficult to quantify. Companies can also use tools like performance reviews, skill assessments, and market benchmarking to provide more tailored and accurate compensation. This approach fosters stronger worker-firm relationships, drives growth, and improves competitiveness. By adopting more thoughtful approaches to wage determination, companies can achieve better outcomes for both the business and its employees.
