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...

Using nationally representative workplace data for Britain we show that over the last quarter century union voice - especially union-only voice - has been associated with poorer climate, more industrial action, poorer financial performance and poorer labour productivity than nonunion voice and,...

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...

Globalization and the ICT revolution of the 1990s have forced many firms to reorganize in order to survive in a more competitive market. There are several approaches that can be used to assess the measurement of organization capital since it is unobservable. Using an optimizing firm model and...

Using nationally representative workplace surveys we examine the relationship between unionization and workplace financial performance in Britain and France. We find that union bargaining is detrimental to workplace performance in Britain and that this effect is larger when unionization is...

A major empirical challenge in economics is to identify how regulations (such as firing costs) affect economic efficiency. Almost all countries have regulations that increase costs when firms cross a discrete size threshold. We show how these size-contingent regulations can be used to identify...

We use Belgian manufacturing firm-level data over the period 1996- 2007 to analyze the impact of imports from different origins on firm growth, exit, and skill upgrading. For this purpose we use both industry-level and firm-level imports by country of origin and distinguish between firm-level...

Women have, on average, been less well-paid than men throughout history. Prior to 1900, most economic historians see the gender wage gap as a reflection of men's greater strength and correspondingly higher productivity. This paper investigates the gender wage gap in cigar making around 1900....

This paper analyses the continued decline of trade unions in Britain and examines the possible implications for workers, employers, and unions themselves. Membership of trade unions declined precipitously in the 1980s and 1990s. The rate of decline has slowed in the most recent decade, but we...
