The paper develops a model of proportionate growth to describe the dynamics of international trade flows. We show that a large number of the empirical regularities characterizing international trade -such as the fraction of zero trade flows across pairs of countries, the positive relationship...

This paper contributes to the literature explaining firm-level heterogeneity in the extensive margin of trade, defined as the number of products exported by each firm. We develop a dynamic model where firms must invest in R&D to maintain and increase their portfolio of goods: the process of...

The paper develops a simple model to describe the dynamics of international trade flows. We show that such a setup is able to simultaneously match a large number of empirical regularities, such as the fraction of zero trade flows across pairs of countries, the positive relationship between...

In this paper we show the benefits of regional connectivity and specialization to growth. Starting with one region we show how welfare measured by utility per head increases as the number of connected regions increase. We assume a common connectivity infrastructure implemented by satellite,...

This paper contrasts the poor performance of African economies over the past 30 years with the remarkable development of East Asian newly industrialized countries. It provides evidence that the lack of diversification, stemming from the adoption of inward-looking strategies, interventionist...

The objective of this study is to analyze the performance of Brazilian exports of industrialized products in the period 2005-2016, with approaches that allow identifying some factors that characterize this process, not only at the level of industrial activity as a whole, but also in terms of the...
