This paper describes the implementation of a new protocol for the regular economics seminar run by the Economics Department of ISEG and the research center UECE during academic year 2010-2011. The main innovative features of this protocol were: the introduction of a discussant that explains the...

This paper deals with the location of input supply in a two country spatial economy. A duopoly supplies intermediate goods to a perfectly competitive consumer good industry that operates with a quadratic production function inspired in PENG, THISSE and WANG (2006). Since the consumer good is...

The paper deals with a location game involving two symmetric firms. The players choose strategies in a spatial setting made up by two asymmetric countries,where the smallest country has a labour cost advantage. Determination of equilibrium location patterns enables to assess under what...

This paper models the decision of vertically-linked firms to build either partitioned or connected networks of supply of an intermediate good. In each case, the locations of upstream and downstream firms are correlated. Input specificity is related both to variable costs (transport costs of the...

The paper surveys the main trends of per capita income convergence in the European Union. It stresses that income disparities have ceased to diminish across the European regions since 1980, although convergence between countries has continued in this period. Income levels have diverged inside...

Main trends of per capita income convergence in Portugal and the European Union are surveyed. An explanation is given to the fact that in the last two decades countries have converged, while no visible convergence has taken place among the regions belonging to a given country. A theoretical...

This paper models, in game-theoretical terms, the location of two vertically-linked monopolistic firms in a spatial economy formed by a large, high labor cost country and a relatively small, low labor cost country. It is found that the decrease in transport costs shifts firms towards the low...

The paper treats a noncooperative game where an upstream firm and two downstream firms select locations in a spatial system made by two asymmetric countries. The location of the upstream firm is indeterminate and it is assigned to the smaller country, in order to avoid triviality of the location...

The importance and the impacts of horizontal multinational corporations in the context of integration and economic growth processes are examined. A noncooperative game with two firms that choose to have either one or two plants located in two asymmetric countries is used. The firms compete...
