  abstract  = {Existing theoretical literature fails to explain satisfactorily the differences between the pay of workers who are covered by collective agreements and others who are not. This study aims at providing a model framework that is amenable to an analysis of this issue. Our general-equilibrium approach integrates a dual labor market and a two-sector product market. The results suggest that the so-called "union wage gap" is largely determined by the degree of centralization of the bargains and, to a somewhat lesser extent, by the expenditure share of the unionized sector's goods},

  abstract  = {This study examines in which cases economic forces or historical singularities prevail in the determination of the spatial distribution of retail shops. We develop a model of location choice in discrete space. The main force towards an agglomerated structure is the reduction of transaction costs for consumers if retailers are located closely, whilst competition and transport costs work towards a disperse structure. We assess the importance of the initial conditions by simulating the resulting distribution of shops for identical economic parameters but varying initial settings. If the equilibrium distributions are similar we conclude that economic forces have prevailed, while dissimilarity indicates that 'history' is more important. The (dis)similarity of distributions of shops is calculated by means of a metric measure.},
