This paper tests some of the predictions of recent advances in trade theory that have focused on different trade patterns of firms within the same sector. Helpman, Melitz and Yeaple (2005) develop a model in which innate productivity differences between firms determine the degree of...

The decision of companies to enter international markets, either via exports or foreign direct investment (FDI), has been postulated by the self-sorting model of Helpman, Melitz and Yeaple (HMY, 2004). In the strict sense, the theoretical predictions of HMY only apply to firms that become...

In this paper, we analyze the joint effect of persistency in innovation and export on firms' total factor productivity (measured in accordance with Levinsohn and Petrin, 2003). For this purpose, we use data on Italian manufacturing firms covering an eight-year time span (1998-2006) which allow...

Many empirical papers tested the theoretical predictions of Helpman, Melitz and Yeaple (HMY, 2004) which sorts firms at different internationalization states according to their productivity levels. While these papers ignore the fact, that the theoretical predictions of HMY only apply to firms...

We provide novel evidence on the micro-structure of international trade during the 2008 financial crisis and subsequent global recession exploring a rich firm-level data set from Spain. The analysis is motivated by the surprisingly strong export performance of Spain in the aftermath of the great...

This paper focuses on self-selection into trade by exporting and importing firms, and on the presence of differential variable and sunk costs between exporters and importers across different categories of imports. In addition the authors consider the role of intensive and extensive margins with...

This paper will assess the importance of internal firm resources in overcoming sunk entry costs associated with export. When firms are not able to raise additional external funds for investments, they are credit-constrained, and in such a case, new exporters have to rely on their internal...

Most of the empirical studies on the micro-level effects of exporting on productivity pay little attention to the potentially heterogeneous effects of the different modes of export market entry. We study how productivity of firms is affected by export entry simultaneously into several markets or...

Motivated by the longstanding interest of economists in understanding the nexus between firm productivity and export behavior, this paper develops a novel structural framework for control-function-based nonparametric identification of the gross production function and latent firm productivity in...
