We reconsider the justifications of the R&D subsidies of Spencer and Brander (1983), by allowing firms to form a research joint venture (RJV) and license innovations. If governments offer unconditional subsidies, an RJV is formed and the strategic benefits of R&D subsidies vanish. Nevertheless,...

We show that, even under incomplete markets, the equilibrium manifold identifies individual demands everywhere in their domains. Under partial observation of the manifold, we determine maximal subsets of the domains on which identification holds. For this, we assume conditions of smoothness,...

This paper explores how the costs of disclosing evidence affect the attainment of desirable outcomes in contractual relationships with complete information. Not only does evidence production cost influence the players' incentives to disclose evidence, it also affects their willingness to...

By revisiting the classic dirty-face problem we highlight the notion of `unawareness' (a simpler state space) and compare it with `impreciseness' (a coarser information partition). The outcomes are derived with various information structures. That allows us to 1) demonstrate a model of differing...

Comparative statics for all-pay auctions with two heterogeneous and privately informed bidders are analyzed. General results are provided for when one bidder becomes stochastically weaker. The comparative statics are fully characterized for truncations. Moreover, we show that expected revenue...

We establish mathematical equivalence between independence of irrelevant alternatives and monotonicity with respect to first order stochastic dominance. This formal equivalence result between the two principles is obtained under two key conditions. Firstly, for all natural numbers m, each...

This paper develops a model of competition among multiproduct retailers that is consistent with observed pricing regularities, such as the facts that virtually all products have large mass points in their price distributions and that most deviations fall below these mass points. The basis of the...

In this paper we revisit the first price and the second price sealed-bid auctions, but, unlike the standard model, we assume that bidding is conducted by an expert on behalf of the client, and that the client does not completely trust the expert's qualifications. In particular, if the client...

This paper analyses comparative statics for first price auctions and all pay auctions with independent private values. In all pay auctions, bidders with low values will respond to a stochastically higher (in the sense of likelihood ratio dominance) distribution of types by playing less...

We analyze credit market equilibrium when banks screen loan applicants. When banks have a convex cost function of screening, a pure strategy equilibrium exists where banks optimally set interest rates at the same level as their competitors. This result complements Broecker's (1990) analysis,...
