In response to high mortality rates and low productivity in coal mining, China began regulating coal mines in the 1990s, reshaping its coal economy. We investigate the relationship between coal mine regulation and economic growth. Using the difference-in-difference approach to compare the pre- and post-regulation periods as well as reg…

Delineating the patent scope consistently with the contribution of the disclosed invention is one of the most crucial requirements for a patent system to promote innovation effectively. Given the incentive of an applicant to set a scope for the patent as broad as possible, an important task of the Patent Office is to narrow it so that …

We develop a competitive search model involving multiple regions, geographically mobile workers, and moving costs. Equilibrium mobility patterns are analyzed and characterized, and the results indicate that shocks to a particular region, such as a productivity shock, can propagate to other regions through workers' mobility. Moreover, e…

This paper shows descriptively how the knowledge network in East Asia has been formed. In addition, the correlation between the knowledge network and economic growth is also examined. Evidence is provided to show that plugging into the knowledge network of developed economies could be a key for increasing innovativeness in an economy.

The merger paradox in Cournot oligopoly is revisited in the presence of R&D investment. Two cases are presented in which firms merge profitably without satisfying the 80-percent threshold requirement of Salant et al. (1983).

Recent empirical studies document that knowledge spillovers attenuate and industry localization decays with distance. It is thus imperative to detect localization accurately especially at short distances. We propose a new approach to testing for localization that corrects the first-order bias at and near the boundary in existing method…

In the United States, brand-name drug manufacturers often pay generic companies to delay marketing of their generic products. In this paper we develop an analytical framework to examine the implications of banning reverse payment settlements. We first find that reverse payment settlements occur when generic firms face relatively high e…
