We develop a general equilibrium model with heterogeneous firms à la Melitz (2003), where both the government and firms can invest into R&D to improve the country’s technological potential. A higher technological potential raises the average productivity of firms, thus implying lower consumer...

This paper investigates the relation between firms' productivity and exporting behavior in presence of export intermediaries. Using a cross section of firm-level data for several advanced and developing economies, the study confirms the productivity-sorting prediction according to which domestic...

This paper aims at investigating the evolution of the employment and wage structure of Italian manufacturing firms in the early 2000s. The work analyzes whether skills and wage movements have been taken place between or within sectors, and within sector, between or within firms. We show that...

This paper examines the factors that give rise to intermediaries in exporting and explores the implications for trade volumes. Export intermediaries such as wholesalers serve different markets and export different products than manufacturing exporters. In particular, high market-specific fixed...

This paper develops a theoretical model of trade and environmental emissions with heterogeneous firms, where firms make abatement investments and thereby affect their level of emissions. We show that investments in abatement are positively related to firm productivity and firm exports, while...

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...

(english) The article seeks to clarify the relationship between financial development with the proportion of exporting firms and the volume of exports. A theoretical model is developed with two countries at different levels of financial restriction and cost, several sectors differentiated by...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

We propose a stylized monopolistic competition model of international trade where firms differ with respect to the expected economic lifetime of their innovations. Upon entry, they receive a commonly observed signal which is updated over time. Jointly with partial irreversibility of investment,...

Arkolakis, Costinot and Rodriguez-Clare (ACR, 2012) prove that, conditional on the change in openness, the welfare gains from foreign trade reforms are quantitatively identical across single-sector trade models with radically different micro-foundations. We generalize this result to domestic and...
