Group Identity and Social Preferences

American Economic Review 2009 99(1), 431-457
We present a laboratory experiment that measures the effects of induced group identity on social preferences. We find that when participants are matched with an ingroup member, they show a 47 percent increase in charity concerns and a 93 percent decrease in envy. Likewise, participants are 19 percent more likely to reward an ingroup match for good behavior, but 13 percent less likely to punish an ingroup match for misbehavior. Furthermore, participants are significantly more likely to choose social-welfare-maximizing actions when matched with an ingroup member. All results are consistent with the hypothesis that participants are more altruistic toward an ingroup match.

Effects of an Information Sharing System on Employee Creativity, Engagement, and Performance

Journal of Accounting Research 2018 56(2), 713-747
Many service organizations rely on information sharing systems to boost employee creativity to meet customer needs. We conducted a field experiment in a retail chain, based on a registered report accepted by JAR, to test whether an information sharing system recording employees’ creative work affected the quality of creative work, job engagement, and financial performance. We found that, on average, this system did not have a significant effect on any of these outcomes. However, it significantly improved the quality of creative work in stores that had accessed the system more frequently and in stores with fewer same‐company nearby stores. It also improved creative work and job engagement in stores in divergent markets, where customers needed more customization. We found weak evidence of better financial results where salespeople had lower creative talent before the system was introduced. Our findings shed light on those conditions in which information sharing systems affect employees’ creative work.

Labor Market Discrimination against Family Responsibilities: A Correspondence Study with Policy Change in China

Journal of Labor Economics 2023 41(2), 361-387
China shifted its controversial one-child policy (1979–2015) to a two-child policy in 2016. We take advantage of this unexpected policy change and the heterogeneities in the prechange environment to investigate labor market discrimination against expected family responsibilities. In a two-wave correspondence study before and after the policy change, we sent 8,848 fictitious resumes with ages 22–29 in response to online job advertisements. Their gender and only-child/siblinged status were systematically varied. We find that women—but not men—are subject to labor market discrimination for expected family responsibilities. This discrimination worsens with the increase in women’s reproductive age.

Can Staggered Boards Improve Value? Causal Evidence from Massachusetts*

Contemporary Accounting Research 2021 38(4), 3053-3084
Staggered boards (SBs) are one of the most potent common entrenchment devices, and their value effects are considerably debated. We study SBs' effects on firm value, managerial behavior, and investor composition using a quasi‐experimental setting: a 1990 law that imposed SBs on all Massachusetts‐incorporated firms. We find that relative to a matched control group of companies, for treated companies the law led to an increase in Tobin's Q, investment in capital expenditures and R&D, patents, and higher‐quality patented innovations, resulting in higher profitability. These effects are concentrated in innovating firms, especially those facing greater Wall Street scrutiny. An increase in institutional and dedicated investors also accompanied the imposition of SBs, facilitating a longer‐term orientation. The evidence suggests that SBs can benefit early‐life‐cycle firms facing high information asymmetries by allowing their managers to focus on long‐term investments and innovations.

The Effect of Target Difficulty on Target Completion: The Case of Reducing Carbon Emissions

The Accounting Review 2016 91(5), 1467-1492
Targets are an integral component of management control systems and play a significant role in achieving desirable performance outcomes. We focus on a key environmental performance objective—reduction of carbon emissions—as a setting in which to examine how target difficulty affects the degree of target completion in long-term non-financial performance. We use a novel dataset compiled by the Carbon Disclosure Project (CDP) and find that firms setting more difficult targets complete a higher percentage of such targets. We also find that this effect is negatively moderated by the provision of monetary incentives. We corroborate this evidence by showing that target difficulty is more effective for carbon reduction projects requiring more novel knowledge and in high-pollution industries. We discuss limitations and suggest avenues for future research.

Social Comparisons and Contributions to Online Communities: A Field Experiment on MovieLens

American Economic Review 2010 100(4), 1358-1398
We design a field experiment to explore the use of social comparison to increase contributions to an online community. We find that, after receiving behavioral information about the median user's total number of movie ratings, users below the median demonstrate a 530 percent increase in the number of monthly movie ratings, while those above the median decrease their ratings by 62 percent. When given outcome information about the average user's net benefit score, above-average users mainly engage in activities that help others. Our findings suggest that effective personalized social information can increase the level of public goods provision.
