Martin, Ralf - London School of Economics (LSE) - 2008

A startling fact of firm level productivity analysis is the large and persistent differences in both labour productivity and total factor productivity (TFP) between firms in narrowly defined sectoral classes. The competitiveness of an industry is potentially an important factor explaining this...

What is 'firm heterogeneity' in trade models? The role of quality, scope, markups and cost

Hottman, Colin; Redding, Stephen; Weinstein, David E. - London School of Economics (LSE) - 2014

We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the...

Why do management practices differ across firms and countries?

Bloom, Nick; Van Reenen, John - London School of Economics (LSE) - 2010

Economists have long puzzled over the astounding differences in productivity between firms and countries. For example, looking at disaggregated data on U.S. manufacturing industries, Syverson (2004a) found that plants at the 90th percentile produced four times as much as the plant in the 10th...

Minimum wages and firm profitability

Draca, Mirko; Machin, Stephen; Van Reenen, John - London School of Economics (LSE) - 2006

Although there is a large literature on the economic effects of minimum wages on labour market outcomes (especially employment), there is hardly any evidence on their impact on firm performance. This is surprising: minimum wages appear to have a significant impact on wages, but only a limited...
