June 2014Ode to the sea: Workplace Organizations and Norms of Cooperation
with Uri Gneezy, Andreas Leibbrandt, John A. List: w20234
The functioning and well-being of any society and organization critically hinges on norms of cooperation that regulate social activities. Empirical evidence on how such norms emerge and in which environments they thrive remains a clear void in the literature. To provide an initial set of insights, we overlay a set of field experiments in a natural setting. Our approach is to compare behavior in Brazilian fishermen societies that differ along one major dimension: the workplace organization. In one society (located by the sea) fishermen are forced to work in groups whereas in the adjacent society (located on a lake) fishing is inherently an individual activity. We report sharp evidence that the sea fishermen trust and cooperate more and have greater ability to coordinate group actions t...
November 2012Do Women Avoid Salary Negotiations? Evidence from a Large Scale Natural Field Experiment
with Andreas Leibbrandt, John A. List: w18511
One explanation advanced for the persistent gender pay differences in labor markets is that women avoid salary negotiations. By using a natural field experiment that randomizes nearly 2,500 job-seekers into jobs that vary important details of the labor contract, we are able to observe both the nature of sorting and the extent of salary negotiations. We observe interesting data patterns. For example, we find that when there is no explicit statement that wages are negotiable, men are more likely to negotiate than women. However, when we explicitly mention the possibility that wages are negotiable, this difference disappears, and even tends to reverse. In terms of sorting, we find that men in contrast to women prefer job environments where the 'rules of wage determination' are ambiguous. This...
November 2010Do Competitive Work Places Deter Female Workers? A Large-Scale Natural Field Experiment on Gender Differences in Job-Entry Decisions
with Jeffrey A. Flory, Andreas Leibbrandt, John A. List: w16546
Recently an important line of research using laboratory experiments has provided a new potential reason for why we observe gender imbalances in labor markets: men are more competitively inclined than women. Whether, and to what extent, such preferences yield differences in naturally-occurring labor market outcomes remains an open issue. We address this question by exploring job-entry decisions in a natural field experiment where we randomized nearly 7,000 interested job-seekers into different compensation regimes. By varying the role that individual competition plays in setting the wage, we are able to explore whether competition, by itself, can cause differential job entry. The data highlight the power of the compensation regime in that women disproportionately shy away from competitive w...
