Lab Labor: What Can Labor Economists Learn from the Lab? *This paper surveys the contributions of laboratory experiments to labor economics. We begin with a discussion of methodological issues: why (and when) is a lab experiment the best approach; how do laboratory experiments compare to field experiments; and what are the main design issues? We then summarize the substantive contributions of laboratory experiments to our understanding of principal-agent interactions, social preferences, unionfirm bargaining, arbitration, gender differentials, discrimination, job search, and labor markets more generally.

We thank Michael Kuhn and Loni Spilberg for excellent research assistance. We have done our utmost to identify as many lab experimental papers in labor economics as possible, and to represent the results of these papers accurately. Given the volume of recent research in this area and the deadline we have faced in writing this review, it is inevitable that we have missed some important work. We also sincerely hope that we have not mischaracterized any paper's conclusions. The authors apologize for these limitations in advance and nevertheless hope that our review provides a helpful guide to the 'lab labor' literature to date.The economics literature has witnessed an explosion of laboratory experiments in the past 20 years. Many of these experiments have focused on topics that are central to the field of labor economics, including how workers respond to various forms of compensation, and the economics of discrimination, arbitration, bargaining, and matching. In this chapter we survey the contributions of laboratory experiments to our understanding of these questions.We begin our review with a discussion of methodological issues: First, we pose the general question of why (and more importantly when) a labor economist might want to conduct a laboratory experiment: What types of questions, if any, are laboratory experiments best suited to answer? How do laboratory experiments compare to field experiments? Next, once one has decided to conduct a laboratory experiment, how should it be designed? Here we review the main methodological decisions an experimenter typically needs to make, and the advantages and disadvantages of the various choices.The second half of our review turns its attention to the substantive issues in labor economics that have been addressed using laboratory experiments. While these are wideranging, we focus our review on the set of issues that have generated probably the largest volume of experimental papers in labor economics: the effects of compensation policies on the supply of effort by workers. We do this in two parts. The firs...
