Data on all generic drug entries in the period 1984-1994 are used to estimate which markets heterogeneous potential entrants will decide to enter. I find that organizational experience predicts entry. Firms tend to enter markets with supply and demand characteristics similar to the firm's...

This paper proposes a strategic model of entry that allows for positive and negative spillovers among firms. The model is applied to a novel dataset containing information about the store configurations of all US regional shopping centers and is used to quantify the magnitude of inter-store...

I use data on all generic drug approvals granted from 1984- 1994 to examine whether generic entrants are choosing to enter markets based on the characteristics of their current portfolio of drugs. The findings suggest that a firm's previous experience with a drug or therapy reduces its cost of...

Surveys of cartel proceedings reveal that illegal cartels usually (1) attempt to minimize the risk of detection, (2) achieve merely imperfect levels of collusion, (3) compete against some fringe firms, and (4) adjust to market entries and exits. By contrast, existing oligopoly models of...

This paper studies the effect of human capital on the regional entry of firms. An econometric model for a system of disjoint regions and frequency data is constructed, making the comparison between the regions a random discrete choice problem. Empirical evidence from Swedish labour market...

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer's surplus possibly decrease. We first derive the price and the consumer's surplus of a monopoly which is located at the center of the market. When a...

We consider the interaction between an incumbent firm and a potential entrant, and examine how this interaction is affected by demand fluctuations. Our model gives rise to procyclical entry, prices, and price-cost margins, although the average price in the market can be countercyclical if the...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...
