This paper is motivated by two 'stylized facts' concerning the dynamics of diffusion of different technologies competing for the same market niche. a) A stable pattern of market sharing with no overwhelming dominant position is rarely observed in markets with network esternalities. Unbounded...

We investigate the impact of labor market concentration on average wages and decompose it into its effects on new hires and incumbents, where incumbents are defined as individuals who were already employed in the same firm the year before. Using administrative data for France, we find that...

We investigate the impact of labor market concentration on stayers' wages, where stayers are defined as individuals who were already employed in the same firm the year before. Using administrative data for France, we show that the elasticity of stayers' wages to labor market concentration ranges...

We exploit long time series of industry-level data in a group of OECD countries to analyze the short-term labor market effects of reforms lowering barriers to entry and dismissal costs. Our estimates show that both policies induce non-negligible transitory employment losses, a result that is...

We investigate the role of local social pressure in shaping the geographical pattern of firms' firing decisions. Using French linked employer-employee data, we show that social pressure exerted by the local communities where firms' headquarters are located induces CEOs to refrain from dismissing...

There is evidence that pro-competitive reforms in an industry with large incumbents induce the latter to re-organise and reduce prices in an attempt to deter entry of new competitors. Using data for three broadly-defined network industries in 23 OECD countries and covering over 30 years, I show...

In this paper we present an international comparison of growth trends in the OECD countries, with a special attention to developments in labour productivity - allowing for human capital accumulation – and multifactor productivity (MFP) - allowing for changes in the composition of fixed...

This paper presents empirical estimates of human-capital augmented growth equations for a panel of 21 OECD countries over the period 1971-98. It uses an improved dataset on human capital and a novel econometric technique that reconciles growth model assumptions with the needs of panel data...

According to Becker [1964], when labour markets are perfectly competitive, general training is paid by the worker, who reaps all the benefits from the investment. Therefore, ceteris paribus, the greater the training wage premium, the greater the investment in general training. Using data from...
