May 2013Product and labor market imperfections and scale economies: Micro-evidence on France, Japan and the Netherlands
with Kozo Kiyota, Jacques Mairesse: w19059
Allowing for three labor market settings (perfect competition or right-to-manage bargaining, efficient bargaining and monopsony), this paper relies on two extensions of Hall's econometric framework for estimating simultaneously price-cost margins and scale economies. Using an unbalanced panel of 17,653 firms over the period 1986-2001 in France, 8,728 firms over the period 1994-2006 in Japan and 7,828 firms over the period 1993-2008 in the Netherlands, we first apply two procedures to classify 30 comparable manufacturing industries in 6 distinct regimes that differ in terms of the type of competition prevailing in product and labor markets. For each of the predominant regimes in each country, we then investigate industry differences in the estimated product and labor market imperfections an...
July 2010Micro-evidence on Rent Sharing from Different Perspectives
with Jacques Mairesse: w16220
This article provides evidence of rent sharing from orthogonal directions by exploiting different dimensions in the same data. Taking advantage of a rich matched employer-employee dataset for France over the period 1984-2001, we consistently compare industry differences in rent-sharing parameters derived from three different approaches. The accounting approach and the standard labor economics approach are compatible with distinct labor bargaining settings (right-to-manage, efficient bargaining, labor hoarding) whereas the productivity approach hinges on the assumption of efficient bargaining. Across the different approaches, we evidently find differences in dispersion of the industry-specific rent-sharing parameter estimates which could be attributable to differences in modeling assumption...
May 2008Panel Data Estimates Of The Production Function And Product And Labor Market Imperfections
with Jacques Mairesse: w13975
Consistent with two models of imperfect competition in the labor market, the efficient bargaining model and the monopsony model, we provide two extensions of a microeconomic version of Hall's framework for estimating price-cost margins. We show that both product and labor market imperfections generate a wedge between factor elasticities in the production function and their corresponding shares in revenue, that can be characterized by a "joint market imperfections parameter". Using an unbalanced panel of 10646 French firms in 38 manufacturing industries over the period 1978-2001, we can classify these industries into six different regimes depending on the type of competition in the product and the labor market. By far the most predominant regime is one of imperfect competition in the produc...
