Sectoral and Aggregate Technology Shocks:Is There a Relationship?

We analyze sector-specific shocks in productivity and demand in 19 manufacturing sectors of the Austrian economy. Based on a structural vector autoregressive model (SVAR) with long-run restrictions developed by Galí (1999) we extract technology and non-technology shocks from sectoral and aggregate data. We study their patterns and relationship by means of a principal components analysis and find a close association of sectoral and macroeconomic non-technology shocks but only a very weak association for technology shocks. Impulse response analysis indicates that for almost all manufacturing sectors as well as the aggregate Austrian economy productivity growth rates experience an immediate increase due to positive technology shocks while hours worked decline. Thereby we confirm Galís results on the level of Austrian manufacturing industries. From regression analysis, we find that our shocks are closely associated to employment growth and output growth but not to investment growth and that the reaction is different for the aggregate economy and manufacturing industries.JEL codes: D24, E23, E32, O30We thank Werner Müller and the participants of the 2004 conference of the Austrian Economic Association (NOeG) for helpful comments.

Sponsorship of the FIFA world cup,shareholder wealth,and the impact of corruption

The Fédération Internationale de Football Association's World Cup (FIFA WC) is one of the most popular sporting events in the world in general and Europe in particular, and famous for the extraordinary amount of sponsorship fees it attracts. To create value for the stockholders of FIFA’s respective commercial affiliates, these sponsorship expenses should be exceeded by (discounted) future cash flows in order to make this investment profitable. This study analyses return effects for stockholders of FIFA WC Commercial Affiliates, while distinguishing between several image scenarios pertaining to FIFA and applying several models for calculating abnormal returns. We find weak evidence for significant positive abnormal returns of announced FIFA sponsorships in case of a stable FIFA image across different return models. In contrast, we find negative abnormal returns when the latest corruption scandals around FIFA became public. We also detect negative price effects when Gianni Infantino was announced as new FIFA president. The image-related price effects become less pronounced for FIFA Partners and initially closed sponsorship contracts. Finally, we do not find any image-related spillover effects for main competitors of firms sponsoring FIFA.     

To draft or not to draft? Inefficiency, generational incidence, and political economy of military conscription

We study the military draft as a form of intergenerational redistribution, taking into account endogenous human capital formation. Introducing the military draft initially benefits the older generation while it harms the young and all future generations. As it distorts human capital formation more severely than an equivalent intergenerational transfer using public debt or pay-as-you-go pensions, the draft can be abolished in a Pareto-improving way if age-dependent taxes are available. In the absence of age-specific taxes, the political allure of the draft can be explained by the specific intergenerational incidence of its costs and benefits.     

The effect of environmental and social performance on the stock performance of european corporations

This paper examines the effect of sustainability performance of European corporations on their stock performance, measured as the average monthly stock return from 1996 to 2001. The econometric analysis is based on common empirical asset pricing models, particularly on the multifactor model according to Fama and French (1993, Journal of Financial Economics, 33:3–56). The consideration of sustainability performance is two-fold: The average sustainability performance of the industry in which a corporation operates and the relative sustainability performance of a corporation within a given industry. The main result is that the average environmental performance of the industry has a significantly positive influence on the stock performance. In contrast, the average social performance of the industry has a significantly negative influence. The variables of the relative environmental or social performance of a corporation within a given industry have no significant effect on the stock performance. As a by-product, the econometric analysis implies that some results of Fama and French (1993, 1996, The Journal of Finance, LI (1):55–84) regarding the risk factors of the multifactor model need not hold true for different observation periods, for different stock markets, and for the use of single stocks (instead of portfolios).

The Costs of Deception: Evidence from Psychology

Recently, it has been argued that the evidence in social science research suggests that deceiving participants in an experiment does not lead to a significant loss of experimental control. Based on this assessment, experimental economists were counseled to lift their de facto prohibition against deception to capture its potential benefits. To the extent that this recommendation is derived from empirical studies, we argue that it draws on a selective sample of the available evidence. Building on a systematic review of relevant research in psychology, we present two major results: First, the evidence suggests that the experience of having been deceived generates suspicion that in turn is likely to affect the judgment and decision making of a non-negligible number of participants. Second, we find little evidence for the reputational spillover effects that have been hypothesized by a number of authors in psychology and economics (e.g., Kelman, H.C., 1967. Psychological Bulletin. 67, 1–11; Davis, D.D. and Holt, C.A., 1993. Experimental Economics. Princeton University Press, Princeton). Based on a discussion of the methodological costs and benefits of deception, we conclude that experimental economists' prohibition of deception is a sensible convention that economists should not abandon.     

On the Conditional Variance of Fuzzy Random Variables

The conditional variance of random variables plays an important role for well-known variance decomposition formulas. In this paper, the conditional variance is defined for fuzzy random variables and some properties are proved, which especially generalize to the mentioned variance decomposition. Moreover, results for two special types of fuzzy random variables and an outlook for possible applications are presented.     

Setting the stage for successful electronic reverse auctions

Based on case survey data, this article provides a framework to help organizations evaluate if electronic reverse auctions (ERAs) are likely to be successful in terms of product cost reductions. The results of logistic regression and correlation analysis underline that it is vital that the product or service to be auctioned can be properly specified and that the companies must spend sufficient time and effort to carefully analyze, understand and, if possible, increase competition among suppliers participating in an ERA. Further recommendations how to instill competition are provided. Organizations should be aware of these conditions and focus purchasing measures prior to an auction accordingly.
