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...

Marshallian districts are locales that accommodate a large number of small firms producing similar goods to be exported and benefit from the accumulation of know-how associated with workers residing there. We study the making of such districts by assuming that the cost function of a firm is a...

The purpose of this paper is twofold. First, we present a new model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this framework can be...

Recent empirical contributions in labor economics suggest that individual firms face upward sloping labor supplies. We rationalize this by assuming that diosyncratic non-pecuniary conditions interact with money wages in workers' decisions to work for specific firms. Likewise, firms supply...

It is not so long ago that policy makers thought that excessive regional disparities would disappear automatically in the long run. Arbitrage possibilities arising from competition and factor mobility were expected to induce a more than average growth performance in lagging regions. Having the...

In a world of globalisation, it is tempting to foresee the 'death of distance' and, once the impediments to mobility have declined sufficiently, to wait for the predictions of the neo-classical theory of factor mobility to materialise. According to this theory, production factors respond to...

We study how the supply of environmentalism, which is defined by psychic benefits (costs) associated with the purchase of high-environmental (low-environmental) qualities, affects the way firms choose their products and the ensuing consequences for the global level of pollution. Contrary to...

By its very nature, transport is linked to trade. Trade being one of the oldest human activities, the transport of commodities is, therefore, a fundamental ingredient of any society. People get involved in trade because they want to consume goods that are not produced within reach. The Silk Road...

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...
