Learning and incentive‐Compatible Mechanisms for Public Goods Provision: An Experimental Study

Journal of Political Economy 1998 106(3), 633-662
This is the first systematic experimental study of the comparative performance of two incentive‐compatible mechanisms for public goods provision: the basic quadratic mechanism by Groves and Ledyard and the paired‐difference mechanism by Walker. Our experiments demonstrate that the performance of the basic quadratic mechanism under a high punishment parameter is far better than that of the same mechanism under a low punishment parameter, which, in turn, is better than that of the paired‐difference mechanism. We estimate three individual behavioral models: an exponentialized relative payoff sum model outperforms the generalized fictitious play model. We also provide a sufficient condition for convergence under the basic quadratic mechanism.

R&D Spillover Effects and Firm Performance Following R&D Increases

Journal of Financial and Quantitative Analysis 2013 48(5), 1607-1634
Abstract We examine how research and development (R&D) incoming spillovers affect long-run firm performance following firms’ R&D increases. We use a stochastic frontier production method to capture R&D incoming spillover effects. Firms reaping more benefits from R&D investment made by other firms experience more improvement in profitability and more favorable long-run stock performance in the post-R&D-increase period. Firms with higher levels of R&D incoming spillovers recruit more key employees from other firms, suggesting that obtaining know-how through hiring is an important source of incoming spillovers. The evidence also shows that firms experiencing more R&D outgoing spillover effects tend to underinvest in R&D.

The strategic choice of payment method in corporate acquisitions: The role of collective bargaining against unionized workers

Journal of Banking & Finance 2018 88, 408-422
Acquirers facing strong union power tend to acquire target firms with cash rather than equity or a mix of cash and equity. A one standard deviation increase in the union power faced by the acquirer increases the odds of choosing cash payment by a factor ranging from 1.26 to 1.57. The effect is stronger when: the acquiring firm is located in states without the right-to-work laws; the interests of managers are more aligned with shareholders in acquiring firms; and acquiring firms’ asset specificity is high. When union power is strong, acquirers making cash payment are associated with a significantly positive announcement return. In addition, they are less likely to experience labor strikes or declines in operating performance, and more likely to obtain wage concessions in collective bargaining in the post-acquisition period than acquirers using other methods of payment. These findings suggest that cash payment allows acquirers to reduce excess liquidity and strengthen their bargaining power with unions.

Board structure, director expertise, and advisory role of outside directors

Journal of Financial Economics 2020 138(2), 483-503
We investigate how a shock to corporate demand for experienced directors (i.e., U.S. Congress’ grant of Permanent Normal Trade Relations status to China in 2000) affects U.S. firms’ board structure and board advisory role. We find that firms appoint more outside directors with China-related experience after the grant. Firms with such directors realize higher returns around announcements of investments involving Chinese firms and better post-deal operating performance, particularly when these directors reside in the U.S. The appointment of directors with China experience is also greeted more positively by the stock market and they gain more board seats after the grant.

Can lenders discern managerial ability from luck? Evidence from bank loan contracts

Journal of Banking & Finance 2018 87, 187-201
We investigate the effect of managerial ability versus luck on bank loan contracting. Borrowers showing a persistently superior managerial ability over previous years (more likely due to ability) enjoy a lower loan spread, while borrowers showing a temporary superior managerial ability (more likely due to luck) do not enjoy any spread reduction. This finding suggests that banks can discern ability from luck when pricing a loan. Firms with high-ability managers are more likely to continue their prior lower loan spread. The spread-reduction effect of managerial ability is stronger for firms with weak governance structures or poor stakeholder relationships, corroborating the notion that better managerial ability alleviates borrowers’ agency and information risks. We also find that well governed banks are better able to price governance into their borrowers’ loans, which helps explain why good governance enhances bank value.

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. (JEL C93, H41, L82)
