Software vulnerability disclosure refers to the publication of vulnerability information before a patch to address the vulnerability has been issued by the software vendor. It has generated intense interest and debate. In particular, there have been arguments made both in opposition to and in...

The empirical saddlepoint distribution provides an approximation to the sampling distributions for the GMM parameter estimates and the statistics that test the overidentifying restrictions. The empirical saddlepoint distribution permits asymmetry, non-normal tails, and multiple modes. If...

We study deviations from the Law-of-One-Price using microeconomic data on the retail prices of approximately 220 individual goods and services across 122 cities located in 79 countries over the period from 1990 to 2000.

This paper provides a step-by-step guide to solving dynamic stochastic games using the homotopy method. The homotopy method facilitates exploring the equilibrium correspondence in a systematic fashion; it is especially useful in games that have multiple equilibria. We discuss the theory of the...

Learning-by-doing and organizational forgetting have been shown to be important in a variety of industrial settings. This paper provides a general model of dynamic competition that accounts for these economic fundamentals and shows how they shape industry structure and dynamics. Previously...
