Professional associations and other producer groups often complain that their reputation is damaged by other groups providing a similar but lower-quality service and that the latter should be regulated. We examine the conditions under which a common regulatory regime can induce...

Group liability in microcredit purports to improve repayment rates through peer screening, monitoring, and enforcement. However, it may create excessive pressure, and discourage reliable clients from borrowing. Two randomized trials tested the overall effect, as well as specific mechanisms. The...

Why did Victorian Britain invest so much capital abroad? We collect over 500,000 monthly returns of British and foreign securities trading in London and the United States between 1866 and 1907. These heretofore-unknown data allow us to better quantify the historical benefits of international...

We propose two algorithms for deciding if the Walrasian equilibrium inequalities are solvable. These algorithms may serve as nonparametric tests for multiple calibration of applied general equilibrium models or they can be used to compute counterfactual equilibria in applied general equilibrium...

Using the World Bank survey of 1500 firms in five Chinese cities, we study whether the presence of foreign firms produces technology spillovers on domestic firms operating in the same city and industry. We find positive spillovers for more backward firms. We analyze the channels of such...

For over twenty years, a voucher system has been used in Chile to promote competition in the educational system between public and private schools. Attending a private subsidized school is associated with increased standardized test scores, but the apparent impact is relatively small....
