This paper results from the research in the framework of the project "Market developments under transition (applied to the petrol and sugar industries)" and its policy implications. A general definition of the problem, the hypothesis and the research methodology are presented in the...

In many markets consumers have imperfect information about the utility they derive from the products that are on offer and need to visit stores to find the product that is the most preferred. This paper develops a discrete-choice model of demand with optimal consumer search. Consumers first...

We present the first empirical estimation of a structural model taking into account explicitly the endogenous buyer power of downstream players facing two part tariffs contracts offered by the upstream level. We consider vertical contracts between manufacturers and retailers where resale price...

A methodology is presented allowing manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market to be introduced. This contribution allows price-cost margins to be recovered from estimates of demand parameters both under linear pricing models...

We present a methodology allowing to introduce manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market. We consider in particular two types of non linear pricing relationships, one where resale price maintenance is used with two part...

We develop and illustrate a methodology for obtaining robust comparative statics results for collusion models in markets with differentiated goods by analyzing the homogeneous goods limit of these models. This analysis reveals that the impact of parameter changes on the incentives to deviate...

This Paper investigates the welfare effects of trade liberalization by exploiting a natural policy experiment in the small open economy of Cyprus. A 1993 law relaxed import restrictions on used vehicles and facilitated the flow of used Japanese vehicles into the country. This led to a dramatic...

We study how smugglers respond to different types of migration policies - legalisation through the sale of migration visas, or more traditional repressive policies through borders' enforcement, employers' sanctions or deportation - by changing the price they propose to illegal migrants. In this...

We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behaviour of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological...

We address the problem faced by innovators who have an idea for a marketable product but must hire employees to bring the product to the market. Information leakage implies that newly-hired employees become informed of the idea and may attempt to bring the product to the market themselves. We...
