Incentives and management accounting: field experiments in firms.

Associate Professor of Managerial Accounting · Frankfurt School of Finance & Management

I study how management accounting and control systems shape behavior in organizations. My research focuses on how firms design and use performance information and incentives, including what these instruments signal to employees.

To identify causal effects, I primarily conduct field experiments in firms, often using data from their management accounting and personnel systems. Depending on the question, I complement these with laboratory and online experiments, surveys, and archival data.

My work on employee attendance and sickness absence contributes evidence to the public debate and is regularly covered in the media.

The Hidden Costs of Dismissals: Behavioral Consequences of Impending Termination

with Jakob Alfitian · Journal of Labor Economics

Forthcoming

Dismissed employees show a sharp rise in absence around the time they receive notice.

This study investigates the impact of impending termination on employee behavior, using comprehensive data from 3,340 employees of a retail chain. Employees who were dismissed exhibit a sharp increase in absenteeism around the time they were given notice. In contrast, employees who resigned show only a moderate increase in absenteeism toward the end of their employment relationship, which is, however, not particularly pronounced around the time they gave notice. The conclusion of a mutual termination agreement between the employer and the employee even tends to be followed by a decrease in absenteeism.

The Algorithmic Assignment of Incentive Schemes

with Saskia Opitz, Dirk Sliwka, and Tom Zimmermann · Management Science, 71(2): 1546–1563

Assigning incentive schemes to workers with a machine learning algorithm raises performance above the single best scheme.

The assignment of individuals with different observable characteristics to different treatments is a central question in designing optimal policies. We study this question in the context of increasing workers' performance via targeted incentives using machine learning algorithms with worker demographics, personality traits, and preferences as input. Running two large-scale experiments, we show that (i) performance can be predicted by accurately measured worker characteristics, (ii) a machine learning algorithm can detect heterogeneity in responses to different schemes, (iii) a targeted assignment of schemes to individuals increases performance significantly above the level of the single best scheme, and (iv) algorithmic assignment is more effective for workers who have a high likelihood to repeatedly interact with the employer or who provide more consistent survey answers.

Social Comparison on Multiple Tasks – Sacrificing Overall Performance for Local Excellence?

with Maximilian Kohler, Matthias D. Mahlendorf, and Mischa Seiter · Journal of Accounting Research, 62(4): 1309–1361

Registered report

Detailed relative performance information can reduce performance, especially in the low-return task.

This field experiment investigates how different levels of aggregation in relative performance information (RPI) impact employee performance in environments with multiple tasks. We randomly assign store employees of a retail chain to three groups: RPI on overall performance (control group), RPI on separate tasks, and RPI on both overall performance and separate tasks. We do not find evidence that providing separate task RPI instead of overall RPI affects performance or effort allocation. However, providing RPI on both overall performance and separate tasks seems to reduce performance, especially in the low-return task. This suggests that detailed RPI directs employees' attention to the smaller benefits of low-return tasks. We further find that only 30.5% of the employees accessed their performance reports, highlighting a distinction between providing RPI in the field and the laboratory. This study is based on a registered report accepted by the Journal of Accounting Research.

When Bonuses Backfire: Evidence from the Workplace

with Jakob Alfitian and Dirk Sliwka · Management Science, 70(9): 6395–6414

A monetary attendance bonus increased absence by around 45%.

Monetary incentives are widely used to align employees' actions with the objectives of employers. We conduct a field experiment in a retail chain to evaluate whether an attendance bonus reduces employee absenteeism. The RCT assigned 346 apprentices for one year to either a monetary attendance bonus, a time-off bonus or a control group. We find that neither form of the bonus reduced absenteeism, but the monetary bonus increased absence by around 45%. This backfiring effect is persistent and driven by the most recently hired apprentices. Survey results reveal that the bonus shifted the perception of absenteeism as acceptable behavior.

Information, Incentives, and Attention: A Field Experiment on the Interaction of Management Controls

with Kathrin Manthei and Dirk Sliwka · The Accounting Review, 98(5): 455–479

Profit information and performance pay each raised profits but did not reinforce each other.

We study the profit effects and interplay of two core accounting practices in a field experiment in a large retail chain. In a 2 × 2 factorial design, we vary (1) whether store managers obtain decision-facilitating information on a profit metric and (2) whether they receive performance pay based on the same metric. We find that both practices increase profits significantly. In contrast to reasoning based on standard economic theory, we do not find complementarity between both interventions. Rather, we detect evidence in line with an attention-directing role of both practices: the introduction of each raises attention to the underlying objective, which induces a countervailing substitution effect.

Research focus

Incentives and what they signal

Bonuses and performance pay change what employees earn. They also tell employees what the firm expects and what is normal. In one field experiment, an attendance bonus increased absence, and survey evidence suggests that it made absence look more acceptable.

Information and control

Firms measure performance and feed it back to employees and managers. I study how relative performance feedback and decision-facilitating information affect effort and attention, and how algorithmic decision tools and digital monitoring change management control.

Attendance and sickness absence

Sickness absence is costly for firms and a recurring topic in public policy debates. My field experiments test what actually reduces absence, from bonus schemes to information about colleagues' absence. This work is regularly covered by national and international media.

In the media

Much of the coverage concerns my research on sickness absence and attendance incentives.
