I study how firms actually compete in nonlinear tariffs by analyzing whether the incumbent and entrant's decisions to offer a given number of tariff options are interrelated. The goal is to shed some light on those dynamic and strategic aspects of tariff menus that are currently ignored by...

In this paper we develop a fully game-theoretic version of the right-to-manage model of firm-level bargaining where strategic interactions among firms are explicitly recognized. Our main aim is to investigate how equilibrium wages and employment react to changes in the labour and product...

We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other...
