OVERINVESTMENT IN TEAM SPORTS LEAGUES: A CONTEST THEORY MODEL

This paper applies contest theory to provide an integrated framework of a team sports league and analyzes the competitive interaction between clubs. We show that dissipation of the league revenue arises from 'overinvestment' in playing talent as a direct consequence of the ruinous competitive interaction between clubs. This overinvestment problem increases if the discriminatory power of the contest function increases, revenue-sharing decreases, and the size of an additional exogenous prize increases. We further show that clubs invest more when they play in an open league compared with a closed league. Moreover, the overinvestment problem within open leagues increases with the revenue differential between leagues.     

Ein Entscheidungsmodell für Konsumieren und Sparen

Summary The present study analyses the simultaneous problem of consumption and saving by means of a consistent demand system; for this purpose the linear—expenditure—system (LES), developed by R. Stone, has been modified and used as a methodological base. Saving takes, for the sake of operationality, the character of a consumer—good and becomes an argument of the utility function. The usual neoclassical assumption of utility maximization allows the derivation of a linear expenditure system of consumption and saving (LESSC) when prices and income are given. The simultaneous LESSC-model has remarkable weaknesses, however: the assumption of certainty, the static character of the model, the disregard for major savings—motives and private expenditure on homebuiding led to bad elasticity—estimates. The assumpion of directly—additive utility functions causes furthermore collinearity between income—and price—elasticities such that the meaning of the derived elasticities is greatly reduced.The income—elasticities derived from the LESSC are positive throughout but show a remarkable variance. The calculation of the Friedman—bias demonstrates a rather strong bias due to the assumption of certainty. A modification resulted in income—elasticities of private consumption and savings of around 0,93 (unmodified: 0,88) and 1,41 (unmodified: 1,76). The demand for consumption goods of great necessity was income—inelastic whereas the demand for goods of less importance to survival was income—elastic. An analysis of income—elasticities of the disaggregated system and the relation between transitory components of consumption and income existing in Austria gave the impression that unexpected changes in income are not only reflected in saving but also in changes of the consumption—structure.The respective price—elasticites are all negative and smaller than 1. For less important consumption—goods lower price—elasticities have been measured and for easily substitutable goods higher ones. Marked crossprice—elasticities could only by discovered with clothing and food products. Generally it can be said that an increase in prices of goods of the daily needs hits both the expenditure on easily substitutable consumption goods and causes dissaving.A comparison with the elasticities calculated through OLS shows a greater reliance of LESSC—elasticities as far as data of differing aggregation levels are concerned.

The production network: An efficient tool in modelling territorial development plans

A rational distribution of productive forces on a country's territory is directly reflected in the saving of social labour, with all its well-known advantages. When one considers this, the importance of modelling territorial forecasts as realistically as possible becomes obvious. Modelling and optimizing a forecast can be done by means of the production network.Technical Economic Aspects. By territorial production network the authors of this paper mean a unitary system of manufacturing centres, in a given industrial sub-branch, which find themselves in a permanently interconditioning position and are distributed throughout the country in such a way that, on the sale of national economy, there should exist a minimum effort of social labour (materialised in investment outlay and in production and circulation expenditure) for meetong home requirements of productive and non-productive consumption and for providing efficient exports. The minimization of the social labour effort constitutes the criterion function of the model.Social Political Aspects. The optimum solution for the sub-branch might not always be adopted on the scale of national economy. This would happen since, in the process of optimizing the production network for each individual industry, a great number of optimal locations might be concentrated at a limited number of geographical points, thus generating territorial disparities in the economy as a whole. To prevent this happening, it becomes necessary, after determining from the economic standpoint the best production network for all industrial sub-branches, to find a rational way of socially harmonizing the people's material and cultural standards in all the various areas of the country. One might, for instance, harmonize the inter-zonal net industrial output per capita, since the net output represents in fact the added value created in the social process of extended reproduction.A solution to this problem will secure an efficient dynamic equilibrium of the industrial output potential between the various areas of a country and per successive plan stages and, implicitly, a faster rise in living standards for the population in the economically less developed areas.     

The Precautionary Principle as a Framework for a Sustainable Information Society

The precautionary principle (PP) aims to anticipate and minimize potentially serious or irreversible risks under conditions of scientific uncertainty. Thus it preserves the potential for future developments. It has been incorporated into many international treaties and pieces of national legislation for environmental protection and sustainable development. In this article, we outline an interpretation of the PP as a framework of orientation for a sustainable information society. Since the risks induced by future information and communication technologies (ICT) are social risks for the most part, we propose to extend the PP from mainly environmental to social subjects of protection. From an ethical point of view, the PP and sustainability share the principle of intergenerational justice, which can be used as an argument to preserve free space for the decisions of future generations. Applied to technical innovation and to ICT issues in particular, the extended PP can serve as a framework of orientation to avoid socio-economically irreversible developments. We conclude that the PP is a useful approach for: (i) policy makers to reconcile information society and sustainability policies and (ii) ICT companies to formulate sustainability strategies.     

Wie die deutsche Einheit die Länder im Finanzausgleich belastet hat

In Germany there is a political consensus that the economic and fiscal burden of the German reunification should be shared by all three jurisdictional levels of the federal system. According to existing law, the burden-sharing between the state and local authorities has to be confined to the excess burden which follows from the financing of the German Unity Fund as well as the integration of the eastern German states into the fiscal equalisation system. State and local authorities are in conflict with each other regarding an appropriate economic estimate of the excess burden to be caused by the fiscal equalisation system. Against this background, the paper estimates the average excess burden of the western German states as a whole as well as individual excess burdens of selected German states for the time period 1995 to 2009 by applying a multivariate data analysis.
