Many trade models of monopolistic competition identify cost efficiency as the main determinant of firm performance in export markets. To date, the analysis of demand factors has received much less attention. We propose a new model where consumer preferences are asymmetric across varieties and...

The recent availability of trade data at a firm-product-country level calls for a new generation of models able to exploit the large variability detected across observations. By developing a model of monopolistic competition in which varieties enter preferences non-symmetrically, we show how...

We develop a stylized model of international tax competition between a large country and a tax haven. In the large country, firms in a monopolistically competitive industry generate positive profits which can be taxed by the government. Firms have heterogeneous productivity levels and can choose...

This paper derives optimal trade and domestic taxes for a small open economy containing a monopolistically competitive (MC) sector in which firms may have heterogeneous productivity levels. Domestic protection brings gains from expanding the number of product varieties on offer, but these gains...

This paper derives optimal trade and domestic taxes for a small open economy containing a monopolistically competitive (MC) sector in which firms may have heterogeneous productivity levels. Analysis encompasses cases in which the domestic MC sector is able to expand or contract flexibly, or is...

This paper examines the role of imported inputs in cushioning exchange rate shocks by using a partial equilibrium model of heterogeneous firms. Producers in the model can serve the domestic market, export final goods, import inputs or engage in both exporting and importing. In the model, an...

This paper analyzes antidumping (AD) policies in a two- country model with heterogeneous firms. One country enforces AD so harshly that firms exporting to the country choose not to dump. In the short run, the country enforcing AD experiences reduced competition to the benefit of local firm and...

This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an...
