|July 2017||Multi Product Firms, Import Competition, and the Evolution of Firm-product Technical Efficiencies|
with Emmanuel Dhyne, Amil Petrin, Valerie Smeets: w23637
We study how increased import competition affects the evolution of firm-product technical efficiencies in the small open economy of Belgium. We observe quarterly firm-product data at the 8-digit level on quantities sold and firm-level labor, capital, and intermediate inputs from 1997 to 2007, a period marked by stark declines in tariffs applied to Chinese goods. Using Diewert (1973) and Lau (1976) we show how to estimate firm-product quarterly technical efficiencies using a multi-product production (MPP) function that avoids using single-product (SP) production func- tion approximations to it. We find that a 0.01 increase in the import share leads to a 1.05% gain in technical efficiency. This elasticity translates into gains from com- petition over the sample period exceeding 1.2 billion e...
|March 2016||Rethinking Deindustrialization|
with Andrew B. Bernard, Valerie Smeets: w22114
Manufacturing in high-income countries is on the decline and Denmark is no exception. Manufacturing employment and the number of firms have been shrinking as a share of the total and in absolute levels. This paper uses a rich linked employer-employee dataset to examine this decline from 1994 to 2007. We propose a different approach to analyze deindustrialization and generate a series of novel stylized facts about the evolution. While most of the decline can be attributed to firm exit and reduced employment at surviving manufacturers, we document that a non-negligible portion is due to firms switching industries, from manufacturing to services. We focus on this last group of firms before, during, and after their sector switch. Overall this is a group of small, highly productive, import inte...

|July 2009||Markups and firm-level export status|
with Jan De Loecker: w15198
Estimating markups has a long tradition in industrial organization and international trade. Economists and policy makers are interested in measuring the effect of various competition and trade policies on market power, typically measured by markups. The empirical methods that were developed in empirical industrial organization often rely on the availability of very detailed market-level data with information on prices, quantities sold, characteristics of products and more recently supplemented with consumer-level attributes. Often, both researchers and government agencies cannot rely on such detailed data, but still need an assessment of whether changes in the operating environment of firms had an impact on markups and therefore on consumer surplus. In this paper, we derive an estimating e...
