In this paper we consider a simple model of horizontal differentiation and derive the closed form solutions for the level of the variables in the decentralized economy and in the social planner case. This enables us to analyze consumers’ welfare as a function of the parameter representing...

The pattern of trade observed from firm-product-country data calls for a new generation of models. To address the unexplained variation in the data, we propose a new model of monopolistic competition where varieties enter preferences non-symmetrically, capturing both horizontal and vertical...

This paper studies the effects of product and labour market deregulation on wage inequality and welfare. By constructing an analytically tractable model in which the level of product market competition and the wages are endogenously distributed, I show that even though deregulation in labour...

In this paper, I construct a general equilibrium model in which the labour market exhibits search frictions, whereas Cournot competition is assumed in the goods market. The properties of the long run free-entry equiibrium show that a more competitive product market raises employment, but it has...

The aim of this paper is to draw attention to the role of local industrial networks in a regional development process. We build a one-region model in which we investigate the conditions that make local networks arise, distinguishing between spontaneous and sustained networks. Accounting for the...

The main object of this analysis is to emphasize, empirically, some determinants to exportations and foreign direct investments in Visegrad Area. The interest is to verify whether it is really possible to model location decisions in these countries with proper references already adopted in...

This paper studies the barter industry developed in North America during he 1950s, pointing ut some of its main characteristics. Thus, it examines its two main sectors : (i) Corporate Barter and (ii) Commercial Barter. Contrary to expectations, the analysis of official data shows that this...
