The work of Ghironi and Melitz (2005) is at the frontier of international real business cycle (IRBC) models with heterogeneous firms. In their model, the dynamic behaviour of real marginal costs is puzzling: a positive technology shock hitting the home country makes it permanently less...

The aim of this paper is to compare the price elasticity of import demand in the destination markets of Italian exports to the price elasticity in the destination markets of the other main euro-area countries� exports. To this end, we use the elasticities of substitution across varieties...

We propose a theory-based approach to testing the presence of the 'home market effect' in a multi-country world. Our framework extends Krugman's (1980, Am. Econ. Rev. 70(5), 950-959) model, in which the appeal of a country as a production site depends on both the relative size of its domestic...

We develop a multi-country Dixit-Stiglitz trade model and analyze how industry location and welfare respond to changes in: (i) transport frictions (e.g., infrastructure, transportation technology); and (ii) non-transport frictions (e.g., tariffs, standards and regulations). We show that changes...

We use Italian firm-level data to investigate the impact of trade openness on the distribution of firms across marginal cost levels. In so doing, we implement a procedure that allows us to control not only for the standard transmission bias identified in firm-level TFP regressions but also for...

I analyse the effects of a reduction in the tariffs of a trading partner on the exports of domestic firms. More precisely, I focus on how cross-industry differences in factor intensities and within-industry differences in firm productivities shape the response of the extensive (decision to...

In this paper we investigate two potential channels of international technology transfer towards developing countries: trade and foreign direct investments. We study the extent to which, through these channels, research and development expenditures (R&D) performed by advanced countries affect...

Using data on a sample of Italian manufacturing companies, this paper analyzes the location (at home or abroad) and the mode of organization (outsourcing versus integration) of intermediate inputs production. We find evidence of a productivity ordering (largely consistent with the assumptions in...

This paper shows that vertical specialisation can increase the elasticity of trade to income, hence explaining dramatic events such as the great trade collapse. We argue that a change in the extent of vertical specialisation affects the elasticity of trade to income, while a mere change in...

This paper develops a general equilibrium model of international trade with heterogeneous firms and imperfect credit markets. To finance the costs for product innovation and domestic and foreign market entry, firms must raise external capital. The model underscores the importance of considering...
