Gasoline prices are said to take longer to decrease and at a slower rate when crude oil prices fall than they do to increase when crude oil prices rise. In this paper I analyze to what extent this asymmetry phenomenon can be identified across all EU15 Member States, plus the EU15 average, and I...

We propose an estimator for discrete choice models, such as the logit, with a nonparametric distribution of random coefficients. The estimator is linear regression subject to linear inequality constraints and is robust, simple to program and quick to compute compared to alternative estimators...

We study the investment of a telecommunications incumbent in quality and in cost reduction when an entrant can use its network through unbundling of the local loop. We fi?nd that unbundling may lower incentives for quality improvements, but raises incentives for cost reduction. Therefore, it is...

We analyze a dynamic durable good oligopoly model where sellers are capacity constrained over the length of the game. Buyers act strategically in the market, knowing that their purchases may affect future prices. The model is examined when there is one and multiple buyers. Sellers choose their...

The received wisdom is that sunk costs create a barrier to entry— if entry fails, then the entrant, unable to recover sunk costs, incurs greater losses. In a strategic context where an incumbent may prey on the entrant, sunk entry costs have a countervailing effect: they may effectively commit...

I consider a dynamic model of competition between two proprietary networks. Consumers die with a constant hazard rate and are replaced by new consumers. Firms compete for new consumers to join their network by offering network entry prices (which may be below cost). New consumers have a...

We extend the literature on knowledge spillovers between firms by studying a dynamic duopoly model of R&D. Our analysis highlights the previously ignored welfare effects of spillovers through dynamic changes in industry concentration. In addition, we find that the impact of imperfect...

We compare different notions of stability in three firm merger games. We discuss some of their shortcomings and introduce an alternative notion of stability which overcomes them. The paper concludes with an illustrative example.
