We study the estimation of static games where players are allowed to have ordered actions, such as the number of stores to enter into a market. Assuming that pay- off functions satisfy general shape restrictions, we show that equilibrium of the game implies a covariance restriction between each...

In this paper, we introduce a new approach to estimating differentiated product demand systems that allows for products with zero sales in the data. Zeroes in demand are a common problem in differentiated product markets, but fall outside the scope of existing demand estimation techniques. We...
