Preferences for Consistency

This paper studies how a preference for consistency can affect economic decision-making. We propose a two-period model where people have a preference for consistency because consistent behavior allows them to signal personal and intellectual strength. We then present three experiments that study main predictions and implications of the model. The first is a simple principal-agent experiment that shows that consistency is valued by others and that this value is anticipated. The second experiment underlines the crucial role of early commitment for consistency preferences. Finally we show how preferences for consistency can be used to manipulate choices.consistency preferences, experiments, early commitment, charitable giving, social influence

Performance Pay and Multi-dimensional Sorting - Productivity, Preferences and Gender

This paper studies the impact of incentives on worker self-selection in a controlledlaboratory experiment. Subjects face the choice between a fixed and a variable paymentscheme. Depending on the treatment, the variable payment is a piece rate, a tournamentor a revenue-sharing scheme. We find that output is higher in the variable pay schemes(piece rate, tournament, and revenue sharing) compared to the fixed payment scheme.This difference is largely driven by productivity sorting. In addition personal attitudessuch as willingness to take risks and relative self-assessment as well as gender affectthe sorting decision in a systematic way. Moreover, self-reported effort is significantlyhigher in all variable pay conditions than in the fixed wage condition. Our lab findingsare supported by an additional analysis using data from a large and representativesample. In sum, our findings underline the importance of multi-dimensional sorting,i.e., the tendency for different incentive schemes to systematically attract people withdifferent individual characteristics.labour economics ;

Psychological Foundations of Incentives

During the last two decades economists have made much progress in understanding incentives, contracts and organisations. Yet, they constrained their attention to a very narrow and empirically questionable view of human motivation. The purpose of this paper is to show that this narrow view of human motivation may severely limit understanding the determinants and effects of incentives. Economists may fail to understand the levels and the changes in behaviour if they neglect motives like the desire to reciprocate or the desire to avoid social disapproval. We show that monetary incentives may backfire and reduce the performance of agents or their compliance with rules. In addition, these motives may generate very powerful incentives themselves.incentives, contracts, reciprocity, social approval, social norms, intrinsic motivation.

Facing Yourself - A Note on Self-image

Numerous signaling models in economics assume image concerns. These take two forms, as relating either to social image or self-image. While empirical work has identified the behavioral importance of the former, little is known about the role of self-image concerns. We exogenously vary self-image concerns in manipulating self-directed attention and study the impact on moral behavior. The choice context in the experiment is whether subjects inict a painful electric shock on another subject to receive a monetary payment. Three between-subjects conditions are studied. In the main treatment, subjects see their own face on the decision screen in a real-time video feed. In the two control conditions, subjects see either no video at all or a neutral video. We find that the exogenous increase in self-image concerns significantly reduces the fraction of subjects inflicting pain

Lab Experiments are a Major Source of Knowledge in the Social Sciences

Laboratory experiments are a widely used methodology for advancing causal knowledge in the physical and life sciences. With the exception of psychology, the adoption of laboratory experiments has been much slower in the social sciences, although during the last two decades, the use of lab experiments has accelerated. Nonetheless, there remains considerable resistance among social scientists who argue that lab experiments lack “realism” and “generalizability”. In this article we discuss the advantages and limitations of laboratory social science experiments by comparing them to research based on non-experimental data and to field experiments. We argue that many recent objections against lab experiments are misguided and that even more lab experiments should be conducted.laboratory experiments, field experiments, controlled variation

Competition and Relational Contracts: The Role of Unemployment as a Disciplinary Device

When unemployment prevails, relations with a particular firm are valuable for workers. As a consequence, a worker may adhere to an implicit agreement to provide high effort, even when performance is not third-party enforceable. But can implicit agreements – or relational contracts – also motivate high worker performance when the labor market is tight? We examine this question by implementing an experimental market in which there is an excess demand for labor and the performance of workers is not third-party enforceable. We show that relational contracts emerge in which firms reward performing workers with wages that exceed the going market rate. This motivates workers to provide high effort, even though they could shirk and switch firms. Our results thus suggest that unemployment is not a necessary device to motivate workers. We also discuss how market conditions affect relational contracting by comparing identical labor markets with excess supply and excess demand for labor. Long-term relationships turn out to be less frequent when there is excess demand for labor compared to a market characterized by unemployment. Surprisingly though, this does not compromise market performance.relational contracts, involuntary unemployment
