Nonlabor Income and Age at Marriage
We exploit China’s heating policy to investigate how nonlabor income affects marriage. From the mid-1950s, the policy gave substantial subsidies to urban residents north of the Huai River. Applying geographic regression discontinuity, we find that with the policy, urban men in the north married 15 months earlier than men in the south. The difference is substantial given that the average age at first marriage is 24.9 years for urban men in the sou…
Law and Innovation
Here, I study the effect of state enactment of the Uniform Trade Secrets Act (UTSA) on R&D among U.S. businesses between 1979 and 1998. Using a new index of the legal protection of trade secrets, I find that the UTSA was associated with higher R&D among larger companies and those in high-tech industries. For the average company in the respective industry, the UTSA was associated with 3.2% more R&D in pharmaceuticals and 3.1% more R&D in computers…
Corruptible Law Enforcers
We study the optimal compensation policy for a corruptible inspector, charged with monitoring pollution from a factory. Our utilitarian approach focuses on the trade-off among corruption, pollution, and enforcement effort. Owing to the strategic interaction between factory and inspector, changes in compensation policy have surprising effects, e.g., raising the penalty for corruption may cause pollution to increase. We find that bribery is an inef…
Marginal Deterrence in Enforcement of Law
The authors characterize optimal enforcement in a setting in which individuals can select among various levels of some activity, all of which are monitored at the same rate but may be prosecuted and punished at varying rates. For less harmful acts, marginal expected penalties ought to fall short of marginal harms caused. Indeed, some range of very minor acts should be legalized. For more harmful acts, whether marginal expected penalties should fa…
Most-Favored-Customer Protection versus Price Discrimination over Time
How should a seller price capacity that has no salvage value to heterogeneous customers whose valuations are private information? There are two periods, and the seller cannot precommit to prices in the later period. One option is price discrimination: first price high, then discount later if excess capacity remains. By offering most-favored-customer protection, the seller can charge more in advance, but will leave capacity unsold with positive pr…
