Football Championships and Jersey Sponsors' Stock Prices: An Empirical Investigation

Corporate sports sponsorship is an important part of many companies? corporate communication strategy. We take the example of major football tournaments to show that sponsorship indeed affects the sponsor?s (stock) market value. We find a statistically significant impact of football results (at an individual game level) of the seven most important football nations at European and World Championships on the stock prices of jersey sponsors. In general, the more important a match and the less expected its result, the higher its impact. In addition, we find a form of ?mere exposure?-effect which contradicts the efficient markets hypothesis.Sports sponsorship, Advertising, Stock market efficiency

Corporate campaign contributions and abnormal stock returns after presidential elections

In the U.S. campaign contributions by companies play a major role in financing election campaigns. We analyze contributions by companies before an election and stock market performance after the election for the presidential elections from 1992 until 2004. We find that (i) the percentage of contributions given to the winner in a presidential election and (ii) the total contribution (divided by market capitalization) have a significant positive impact on a company's stock market performance after an election, with the second factor being more important. Furthermore, we find that hypothetical portfolios of the 30 highest contributors according to (i) would have earned significant abnormal returns of up to 0.54% per month (6.6% p.a.) during the first year after an election. Investing in a portfolio formed according to (ii) would have yielded abnormal returns of up to 1.21% per month (15.5% p.a.) for the same observation period.Presidential Election, Corporate Campaign Contributions, Abnormal Returns

Tax avoidance, tax evasion, and tax flight: Do legal differences matter?

Although from an economic point of view, legal considerations apart, tax avoidance, tax evasion and tax flight have similar effects, namely a reduction of revenue yields, and are based on the same desire to reduce the tax burden, it is likely that individuals perceive them as different and as unequally fair. Overall, 252 fiscal officers, business students, business lawyers, and entrepreneurs produced spontaneous associations to a scenario either describing tax avoidance, tax evasion, or tax flight, and evaluated it as positive, neutral or negative. The results indicate that social representations differ with respect to tax avoidance, tax evasion, and tax flight. Tax evasion was perceived rather negatively, tax flight neutrally, and tax avoidance positively. Tax knowledge was found not to be correlated neither with tax avoidance nor with tax evasion.tax evasion; social representations; tax knowledge

Over-indebtedness and the interplay of factual and mental money management: An interview study

Previous research has shown that money management contributes to over-indebtedness. This article sheds new light on this relation by looking at factual money management and its mental underpinnings, mental accounting. In a conceptual model we propose that fuzzy factual and mental money management practices aggravated by lack of congruency between factual and mental structures play an important role in over-indebtedness. Twenty-five in-depth interviews deliver preliminary support for this proposition. Successful financial control seems to build on efficient and inter-coordinated factual and mental money management. This reduces the willpower necessary for controlling financial behavior and helps to prevent and fight over-indebtedness.debt, money management, mental accounting, self-control

Thar she bursts - Reducing confusion reduces bubbles

To explore why bubbles frequently emerge in the experimental asset market model of Smith, Suchanek and Williams (1988), we vary the fundamental value process (constant or declining) and the cash-to-asset value-ratio (constant or increasing). We observe high mispricing in treatments with a declining fundamental value, while overvaluation emerges when coupled with an increasing C/A-ratio. A questionnaire reveals that the declining fundamental value process confuses subjects, as they expect the fundamental value to stay constant.Running the experiment with a different context (“stocks of a depletable gold mine” instead of “stocks”) significantly reduces mispricing and overvaluation as it reduces confusion.Experimental economics, asset market, bubble, market efficiency, confusion

The value of information in a multi-agent market model

We present an experimental and simulated model of a multi-agent stock market driven by a double auction order matching mechanism. Studying the effect of cumulative information on the performance of traders, we find a non monotonic relationship of net returns of traders as a function of information levels, both in the experiments and in the simulations. Particularly, averagely informed traders perform worse than the non informed and only traders with high levels of information (insiders) are able to beat the market. The simulations and the experiments reproduce many stylized facts of stock markets, such as fast decay of autocorrelation of returns, volatility clustering and fat-tailed distribution of returns. These results have an important message for everyday life. They can give a possible explanation why, on average, professional fund managers perform worse than the market index.Comment: 11 pages, 5 figures, published in EPJ

It is hard to beat the Monkeys - On the Value of Asymmetric Fundamental Information in Asset Markets

In this paper we present results from experimental asset markets and simulations with traders who receive asymmetric information about the fundamental value of an asset. In the experimental markets with repetition insiders outperform the market and uninformed computerized random traders (monkeys) perform equally well compared to average informed traders. This is in line with the results of the equilibrium simulation output in which traders choose between a random strategy and their fundamental strategy. We further find that pattern of average informed not being able to beat the uninformed is not due to their overconfidence but due to the asymmetric information structure of the market.Information economics, experimental economics, agent-based model, overconfidence, value of information

Towards a general theory of tax practice

This article works towards developing a general theory of tax practice by identifying the type of individuals who provide tax services and examining the nature of the fragmented market in which they operate. The empirical studies in the tax practitioner literature have been considered with a view to determining what exactly tax practitioners do and how they interact and deal with the persons on whose behalf they work. This is done with a view to developing a conceptual analysis of their work. Negotiation theory (Wall, 1985) is then posited as a general theory that fits many aspects of tax practitioners and their work, when analysed in this way

Methods of Studying Economic Decisions in Private Households

Research on joint decision-making processes in households is particularly relevant for marketing, especially for understanding who decides what to buy in purchasing decisions and how decision processes evolve. However, the investigation of such complex processes requires adequate research methods to account for the dynamics in close relationships. We provide a critical overview of past research in the arena of economic decision-making among couples, concentrating on methodological issues. After describing different types of decisions we proceed by describing findings on interaction dynamics, including the nature and occurrence of conflicts. In reviewing relationship structures we focus on the dimensions of harmony and power. The descriptive process model utilized includes the partners’ use of influence tactics, as well as the emergence of utility debts at the end of a decision-making process. Reviewing the adequacy of various research methods, observational and survey techniques are discussed as conventional psychological research methods. The Vienna Partner Diary is introduced as novel method and suggested as being useful for collecting data on the complex interaction processes in the everyday life of couples
