The economic effects of reducing and reorganizing working time

This article goes beyond the often ideological debate for and against a reduction in working time and analyses the effects of shorter working time at company and country levels. Logic and experience dictate that such reductions must be accompanied by a process of work reorganization and include financial compensation for those working shorter hours. However, while these three ingredients are indissoluble, not all firms can proceed at the same pace and in the same ways. Nevertheless, the article shows that, as long as implementation proceeds in a decentralized and selective manner and is accompanied by a judicious reorganization of these hours, it could be extremely beneficial to all parties—companies, the state and individuals, both workers and producers.     

The impact of skewness in the hedging decision

The impact of skewness in the hedger's objective function is tested using a model of hedging derived from a third‐order Taylor Series approximation of expected utility. To determine the effect of price skewness upon hedging and speculation, analytical results are derived using an example of cotton storage. Findings suggest that when forward risk premiums and price skewness in the spot asset have opposite signs, speculation increases relative to the mean‐variance model. When the signs are identical, speculation will decrease, contradicting findings of mean‐variance models. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:503–520, 2006     

Corporate Strategy and ethics

Corporate Strategy has emerged as a central metaphor for private-sector enterprise. Given inherent imperfections in markets, one important question to consider is how well the practice of Corporate Strategy contributes to social welfare. An account of the implicit morality of free markets is developed as a standard against which two particular, second best solutions to market imperfections — namely, American federal antitrust policy and Corporate Strategy — are compared. Corporate Strategy is subsequently evaluated in terms of the fundamental principles of Rawls' theory of justice. In both analyses, Corporate Strategy is found to depart significantly and systematically from the standards of social justice. An alternative principle, grounded in the concept of duty, is introduced as a means for reconceptualizing Corporate Strategy.Daniel R.

Regression using mixed annual and quarterly data

By consideration of either Generalised Least-Squares of Theil-Goldberger estimates of equations for which data on the dependent variable is available for a subset of the sample period on only an annual basis, it is shown that best estimates of the equation coefficients may be obtained by Ordinary Least-Squares estimation over the complete set of quarterly observations with quarterly averages substituted for the missing quarterly data, and symmetrically for the corresponding observations on the regressor variables. The approach is extended to the Two-Stage Least-Squares case, and to the (structurally or stochastically) autoregressive case.     

Vertrauen als Gegenstand der ökonomischen Theorie

Der Beitrag vermittelt einen grundlegenden überblick über die Bedeutung des Vertrauens im Rahmen der ?konomischen Theorie. Zun?chst werden ausgew?hlte Ans?tze im Rahmen der betriebswirtschaftlichen Vertrauensforschung diskutiert. Um eine strukturierte Analyse zu erm?glichen, erfolgt eine differenzierte Betrachtung hinsichtlich der neoklassisch und institutionen?konomisch fundierten Perspektive einerseits sowie der sozio?konomischen Perspektive andererseits. Die Diskussion um den Stand der Forschung wird abgerundet durch einen überblick über empirische Ergebnisse der ?konomischen Vertrauensliteratur. Um noch offene Fragen im Rahmen der Forschung zu adressieren, werden im Anschluss die unterschiedlichen Objekte des Vertrauens analysiert, differenziert nach personalen Vertrauen und Systemvertrauen. Zum Abschluss gilt es die Verhaltensrisiken herauszuarbeiten, die mit Vertrauensbeziehungen einhergehen und die Grenzen des Vertrauens in Organisationen zu beleuchten.     

Marx,Sraffa, and Surplus: Observations Prompted by Garegnani (2018)

ABSTRACT

In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory.

可持续发展融入企业管理框架的路径

从“十二五”计划当中不难发现,可持续发展已成为潮流,企业正受到鼓励,将可持续发展融人日常运营当中。许多企业从战略方面开始考虑这一问题,事实上,如何将可持续发展真正融入企业管理框架也一样重要,否则虽然战略很好,但是无法执行。将可持续发展融入框架的方式有很多,但都必须彻底地由上至下地落实。
