Energy demand in the transportation sector of Mexico

This paper report results of an analysis of the demand for energy in the Mexican transport sectors, focusing on the railroad, air transport and motor vehicle modes. The approach is an econometric one with emphasis placed on the structure for each mode. For two of the modes a two-stage approach is employed where in the first stage demands for services from the particular mode are modeled, and in the second stage demand is treated as a derived demand from these transport services. For the motor vehicle mode, gasoline demand is considered as the product of gasoline consumption per vehicle times the total number of vehicles, and then these components are related to economic and structural variables. Diesel demand of motor vehicles is modeled in a more reduced from approach. The principal finding is that changes in income play a more important role in affecting energy demand than do changes in energy prices, especially in the railroad and air transport sectors. For the gasoline and diesel fuel demand in the monitor vehicle sector, however, price is of substantial importance.

New Forms of Employee Involvement at European Level — The Case of the European Company (SE)

This article focuses on important but widely neglected problems of supranational employee involvement both at the level of information and consultation as well as at board level. It takes the most important pattern, the European Company (SE), and presents a systematic empirical analysis of its negotiated forms of worker representation and employee involvement. The questions addressed are: What do these new forms of collective voice and representation at the supranational level look like? What is the relevance of SEs for the development of an emerging system of European industrial relations in a broader perspective? Is the negotiated form of employee involvement likely to lead to new forms of harmonization and convergence or rather to heterogeneity and fragmentation?
