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...

This paper studies the relationship between firm markups and importing intermediate inputs and exporting using detailed firm-level data from Hungary in 1995-2003. We estimate production functions structurally to obtain firm-year-level productivity and markup estimates. We find that importing...

We use a unique cross-section survey of manufacturing firms from four European countries (France, Germany, Italy, Spain) linked with balance sheet data to study the relationship between key aspects of globalization and firm-level markups. The main results are: (i) Exporting is positively...

We combine two detailed datasets on Colombian manufacturing firms and document several stylized facts on exporter heterogeneity of total factor productivity (TFP) and export-market orientation, refining some previously known facts and unveiling some new others. We first show that the exporter...

In this paper we propose a novel method for the price-cost markup estimation and study the relationship between export intensity and the markup. We impose much less restrictive identifying assumptions on technology and adjustment frictions compared to previous studies and use Swedish firm-level...

This paper studies the relationship between firm-level markups and trade status using balance sheet information linked to detailed trade data from Hungary between 1995-2003. We find that importing is strongly positively correlated with markups both across and within firms. We argue that this...

Properly identify the relationship between export and innovation is key to designing efficient policy instruments. However, there is still no consensus on how has to be the direct causal relationship between innovation and export. In this paper the authors develop an empirical analysis for the...

In order to simplify the representation of a technological relationship between inputs and outputs, a production unit's technology must typically satisfy some restrictive conditions, some of them being well known in the literature. This paper presents new results for aggregating labour inputs...
