Sentimental Preferences and the Organizational Regime of Betting Markets

We analyze the price impact of sentimental bettor preferences within a bookmaker betting market. A theoretical model demonstrates that, under reasonable assumptions about the nature of demand in a market with strong competition, the bookmaker will offer lower prices for bets with comparatively stronger demand. Using a sample of more than 16,000 English soccer matches we find evidence that more favorable odds are extended to bets on more popular clubs and that this effect is amplified on weekends when sentimental bettors face lower opportunity costs to wager. Our findings help to explain why the market for sports gambling operates as a hybrid structure with bookmakers able to attract a considerable share of the betting volume, although identical contracts are traded on exchange markets at lower costs: the organizational design of a quote‐driven market enables the dealer to take advantage of sentimental bettor preferences.

Summary For the analysis of the allocation of personal disposable income to the different consumption goods and savings, an indirect-addilog-expenditure-system (IAES) has been constructed. Compared to the linear-expenditure-system (LES) the IAES to far more flexible and is not based upon the idea of minimum-consumption- or minimum-saving-quotas. On the other hand, marginal income shares are not fixed parameters. The IAES allows the derivation of a systematic savings- and consumption-function and supplies consistent income elasticities. But it will be shown that consistent demand systems are only restrictively able to consider all major determinants of the decision-problem consumption or saving. The derived system does not only neglect the effects of wealth on consumption and savings but also the results of real income fluctuations due to the business cycle. Also phenomena like unemployment and uncertainties regarding estimates of the future or inflation are neglected. With the help of an adjustment-procedure a part of these disadvantages has been eliminated. The adjustment with regard to the entire private consumption and savings supplied income elasticities which lead to an almost constant consumption- and savings-share in the period under investigation.     

A Theoretical Analysis of the Influence of Money Injections on Risk Taking in Football Clubs

This paper analyzes the adverse incentive effects produced by money injections of benefactors [sugar daddies (SD)]. We show that the existence of a SD induces the club to choose a riskier investment strategy and the more the SD commits to bailout the club, the more the clubs’ optimal level of riskiness increases. Moreover, a private SD bails out the club less often than a public SD. Our model further shows that a ‘too‐big‐to‐fail’ phenomenon exists because it is optimal to always bailout a club if its market size is sufficiently large.     

Germany’s enduring current account surplus

The Federal Republic of Germany’s balance of payments has been in the black for years, a record unparallelled by any other major country since the Second World War. Proceeding from status quo assumptions, the surpluses are unlikely to decline in the medium term, either.¹ Can they be endured? Do they really pose no serious problem, as current debate on national economic policy suggests?     

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.
