This Paper provides a sufficient condition for the existence and uniqueness of equilibrium in monotone pure strategies, in games of incomplete information. First, we show that if each player's incremental ex post pay-off is uniformly increasing in its own action and type, and its type is...

One of the few stylized facts in international relations is that democracies, unlike autocracies, very rarely fight each other. We examine the sustainability of international peace between democracies and autocracies, where the crucial difference between these two political regimes is whether or...

Consider a market where an informed monopolist sets the price for a good or asset with a value unknown to potential buyers. Upon observing the price, buyers may pay some cost for information about the value before deciding on purchases. To restrict buyer beliefs we generalize the idea of the...

A central insight of agency theory is that when a principal offers a contract to a privately informed agent, the principal trades off ex post efficiency in the bad state of nature against a larger profit in the good state of nature. We report about an experiment with 508 participants designed to...

In this Paper, we examine bank lending decisions in an economy with spillover effects in the creation of new investment opportunities and asymmetric information in credit markets. We show that such features may lead to strategic considerations in the loan extension decision and in the pricing of...

This paper analyses how European anti-dumping policy under imperfect competition affects firm behaviour and domestic welfare. Our theoretical model is the first to complement the European empirical literature on anti-dumping policy (see Messerlin (1989), Hindley (1988), Tharakan and Waelbroeck...

We analyse how sharing rules affect Nash equilibria in Bertrand games, where the sharing of profits at ties is a decisive assumption. Necessary conditions for either positive or zero equilibrium profits are derived. Zero profit equilibria are shown to exist under weak conditions if the sharing...

This paper analyses a situation where market designers create new trading platforms and traders learn to select among them. We ask whether 'Walrasian' platforms, leading to market-clearing trading outcomes, will dominate the market in the long run. If several market designers are competing, we...

Why do people vote? This question received a lot of attention for more than thirty years, and yet remains unanswered. In this Paper, we take stock of existing empirical regularities and argue that we can use them to improve the model of instrumental voting. Once this is done, we show that purely...

In this paper we adopt the Selten-Pool model (1993) framework of language acquisition that is based on the notion of communicative benefits and learning costs. We consider a model with languages that serve as imperfect substitutes and show that under supermodularity of the communicative benefits...
