We define an indirect evolutionary approach formally and apply it to (Tullock)contests. While it is known (Leininger, 2003) that the direct evolutionary approach in the form of finite population ESS (Schaffer, 1988) yields more aggressive behavior than in Nash equilibrium, it is now shown that...

An auction is viewed as a process that in equilibrium generates a binary lottery for each bidder, which the bidder "buys" with his bid. This view allows for a simple way to consistently assess differences in bidding behavior over different bidders and different auctions. E.g. all auctions...

We revisit the fundamental issue of market provision of variety associated with Chamberlin, Spence, and Dixit-Stiglitz when firms sell multiple products. Both products and firms are (horizontally) differentiated. We propose a general nested demand framework where consumers first decide upon a...

This paper analyzes fairness and bargaining in a dynamic bilateral matching market. Traders from both sides of the market are pairwise matched to share the gains from trade. The bargaining outcome depends on the traders’ fairness attitudes. In equilibrium fairness matters because of market...

Dominant investors can influence the publicly available information about firms by affecting the cost of information collection. Under strategic competition, transparency results in higher variability of profits and output. Thus lenders prefer less transparency, since this protects firms when in...

This paper studies product market competition under a strategic transparency decision. Dominant investors can influence information collection in the financial market, and thereby corporate transparency, by affecting market liquidity or the cost of information collection. More transparency on a...
