The same yet different: Worker reports on labour practices and outcomes in a single firm across countries

This paper examines cross-country differences in labour policies and practices and employee performance and attitudes toward work from a sample of nearly 30,000 employees in a large multinational manufacturing firm. The analysis shows: 1) large establishment and country differences in work practices, performance, and attitudes toward work across countries; 2) qualitatively similar responses of workers to work practices across countries; 3) a strong link between the establishment average of employee reports on the quality of labour-management relations and establishment average measures of employee performance 4) a positive relation between average employee performance and average employee-management relations at the country level, but no relation between country level performance in the firm and measures of the extent of national labour regulations or practices.     

Budget preferences and direct utility

This paper extends a result of Sakai, who presented conditions for indirect preferences from which a utility function can be deduced if demand is single valued. It will be shown that—adding a “partial Lipschitz condition”—Sakai's theorem can be extended to multi-valued demand. Our result follows from the extension of a theorem of Hurwicz and Richter, who have shown that, under certain hypotheses on demand correspondences, an upper semicontinuous utility function f exists, so that the set of utility maximal elements μ_f(B) is contained in the choice set h(B) for every budget B. By our partial Lipschitz condition h(B) ?- μ_f(B) also follows.

A reformulation of the theory of demand by compensated demand functions

We present a formal approach to consumer demand by compensated demand functions. In accordance with the integrability theory or with the theory of revealed preference, we do not require the existence of a utility function, but we do assume certain hypotheses concerning functions describing rational behavior. In view of their properties, these functions can be interpreted as compensated demand functions. According to traditional neoclassical consumer theory, Shephard's lemma and the symmetry and negative semidefiniteness of the Slutsky-Hicks matrix can be shown. We shall also see that a convex, continuous, and monotonic preference ordering, which is representable by income compensation functions, can be introduced. It can also be shown that the existence of a compensated equilibrium can be derived within this approach by compensated demand functions. In order to obtain the existence of a compensated equilibrium under less stringent conditions we finally generalize the axioms assuming that a compensated demand correspondence is given.     

Environmental protection and the international raw materials economy

All production of mineral raw materials necessarily involves interference with the natural environment. National rules and regulations on environmental protection are intended to ensure that prospecting for, and the extraction and processing of, raw materials are conducted with as little damage as possible to the ecosystem. The following article surveys the effects of such measures on the international raw materials economy.
