Information and communication technology plays an important role in achieving a higher level of energy efficiency. In particular, energy efficiency can be achieved by integrating information technology into electricity networks to enable the interaction between suppliers and customers (smart...

We investigate empirically how sellers react to changes in the population of their consumers, identifying the effects of demand composition and demand size with limited information on costs. We show how pharmacists in Italy selectively increase the price of some products when they observe in...

Allowing for three labor market settings (perfect competition or right-to-manage bargaining, efficient bargaining and monopsony), this paper relies on an extension of Hall's econometric framework for estimating simultaneously price-cost margins and scale economies. Using an unbalanced panel of...

This paper addresses the applicability of the theory of equalizing differences (Rosen, 1987) in a market in which temporary and permanent workers co-exist. The assumption of perfect competition in the labour market is directly questioned and a model is developed in which the labour market is...

This paper analyzes the impact of labor market competition and skill-biased technical change on the structure of compensation. The model combines multitasking and screening, embedded into a Hotelling-like framework. Competition for the most talented workers leads to an escalating reliance on...

This paper studies cross-sectional heterogeneity in price-cost margins and the extent of rent sharing among 48 sectors and 10738 (mainly manufacturing) firms in France. At the sectoral level, the average price-cost mark-up and the average extent of rent sharing amount to 1.701 and 0.368...

We examine wage-bargaining in a two-sector economy when employers and labor unions in each sector are not always aware of all general equilibrium feedback effects. We show analytically that if agents only consider labor demand effects, low real wages and low unemployment result. With an...

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...

We examine wage bargaining when employers and labor unions do not always take all general equilibrium effects into account but learn a steady state. If agents do hardly consider general equilibrium effects, low real wages and low unemployment results. With an intermediate view, when partial...

Corporate success often resembles a snowball. We show how initial luck in hiring talented people, the resulting technological advantage, superior corporate culture, and status-seeking by workers can make small initial differences generate large differences over time.
