We analyze the competition between two newspapers in a vertical differentiation model where the qualities of the journals are determined endogenously in the first stage of the game. We show that when the advertising revenues per reader increase there is a critical value above which the quality...

We study access pricing by platforms providing internet services or pay-TV to users while they allow advertisers to have access to these users against payment via ads or banners. Users are assumed to be adhaters. It is shown that equilibrium access prices in the users' market are increasing in...

A durable good monopolist faces a continuum of heterogeneous customers who make purchase decisions by comparing present and expected price-quality offers. The monopolist designs a sequence of price-quality menus to segment the market. We consider the Markov Perfect Equilibrium (MPE) of a game...

We develop a simple two-country model of international trade that assumes that there is a fixed cost of doing international trade. We show that this leads to multiple equilibria that can be Pareto-ranked. We examine the stability properties of these equilibria

The papers collected in this volume provide new insights into some important problems of monetary theory and contribute significantly to the development of a new area based on monetary policy games. In Part I the reader will find new results on some specific topics of monetary theory, which are...
