Wage Dispersion and Firm Productivity in Different Working Environments

This article investigates the impact of wage dispersion on firm productivity in different working environments. More precisely, it examines the interaction with: (i) the skills of the workforce, using a more appropriate indicator than the standard distinction between white‐ and blue‐collar workers, and (ii) the uncertainty of the firm economic environment, which has, to our knowledge, never been explored on an empirical basis. Using detailed cross‐sectional linked employer–employee data for Belgium, we find a hump‐shaped relationship between (conditional) wage dispersion and firm productivity. This result suggests that up to (beyond) a certain level of wage dispersion, the incentive effects of ‘tournaments’ dominate (are dominated by) ‘fairness’ and/or ‘sabotage’ considerations. Findings also show that the intensity of the relationship is stronger for highly skilled workers and in more stable environments. This might be explained by the fact that monitoring costs and production–effort elasticity are greater for highly skilled workers, and that in the presence of high uncertainty, workers have less control over their effort–output relation, and associate higher uncertainty with more unfair environments.     

Optimal privatization of vertical public utilities

Abstract We examine restructuring, divestiture, and deregulation of a vertically integrated public utility, (e.g., electricity), from a public finance perspective. How an optimal restructuring plan for the utility depends on the cost of public funds and on the X‐efficiency gains from privatization, how the optimal degree of competition in the upstream and downstream segments are connected, and implications of privatization for consumer prices are examined. The higher the cost of public funds, the more likely the post‐privatization price will exceed the regulated public utility price. The greater the X‐efficiency gains from privatization, the more likely the post‐privatization price will fall.     

Freedom of choice between unitary and two-tier boards: An empirical analysis

We examine board structure in France, which since 1966 has allowed firms the freedom to choose between unitary and two-tier boards. We analyze how this choice relates to characteristics of the firm and its environment. Firms with severe asymmetric information tend to opt for unitary boards; firms with a potential for private benefits extraction tend to adopt two-tier boards. Chief executive officer turnover is more sensitive to performance at firms with two-tier boards, indicating greater monitoring. Our results are broadly consistent with the Adams and Ferreira (2007) model and suggest that gains result from allowing freedom of contract about board structure.     

The Cost Factor in Patent Systems

The objective of this paper is to assess to what extent the cost of patenting affects the demand for patents. The empirical analysis, which focuses on the patent systems of the USA, Japan, and Europe in 2003, leads to the following methodological and empirical conclusions: (1) for a proper international comparison, the size of the market and the average number of claims included in a patent must be accounted for; (2) when the cost per claim per capita (the 3C-index) is considered, a negative linear relationship appears between the cost of patenting and the number of claims that are filed; (3) after the grant of a patent by the EPO, the translation, validation and transaction costs induced by an effective protection in several European countries witness a highly fragmented and very expensive European market for intellectual property; (4) for a patent designating 13 European countries, the 3C-index is about ten (two) times higher than in the US (Japanese) system (for process and translation costs up to the grant); (5) The European market being more than twice as large as the US market in terms of inhabitants, the 3C-index suggests that there would be a clear justification for higher nominal examination fees at the EPO, that would ensure the pursuit of a rigorous granting process.     

Core-stable rings in second price auctions with common values

In a common value auction in which the information partitions of the bidders are connected, all rings are core-stable. More precisely, the ex ante expected utilities of rings, at the (noncooperative) sophisticated equilibrium proposed by Einy et al. [Einy, E., Haimanko, O., Orzach, R., Sela, A., 2002. Dominance solvability of second-prices auctions with differential information. Journal of Mathematical Economics 37, 247–258], describe a cooperative games in characteristic function form, in spite of the underlying strategic externalities. A ring is core-stable if the core of this characteristic function is not empty. Furthermore, every ring can implement its sophisticated equilibrium strategy by means of an incentive compatible mechanism. An example shows that, if the bidders’ information partitions are not connected, rings may no longer be core-stable.
