Effective Taxation of Top Incomes in Germany

We exploit a dataset that includes the individual tax returns of all taxpayers in the top percentile of the income distribution in Germany to pin down the effective income taxation of households with very high incomes. Taking tax base erosion into account, we find that the top percentile of the income distribution pays an effective average tax rate of 30.5% and contributes more than a quarter of total income tax revenue. Within the top percentile, the effective average tax rate is first increasing, then decreasing, with income. Since the 1990s, effective average tax rates for the German super‐rich have fallen by about a third, with major reductions occurring in the wake of the personal income tax reform of 2001–05. As a result, the concentration of net incomes at the very top of the distribution has strongly increased in Germany.     

Deviations from Fundamentals in US and EU Stock Markets: A Comparative Analysis

Abstract

A ‘two-stage growth’ discounted cash flow (DCF) model is built to test whether changes in the underlying market fundamentals help to explain movements in stock prices. Empirical results on two samples of US and EU stocks show that the ‘fundamental’ earning price ratio (E/P) explains a significant share of cross-sectional variation of the observed E/P, this impact being stronger in the US market. It is also found that: (i) the fundamental component of the E/P has superior explanatory power than simpler measures of expected earnings growth; (ii) ‘non-fundamental’ components, interpreted as signals reducing asymmetric information (such as firm size, the number of forecasts and the chartist momentum), mitigate the role of the fundamentals; (iii) current deviations from the fundamentals are affected by ex post adjustment of publicly available information in the EU sample. It is argued that differences in regulatory environments and in the composition of investors between the US and EU financial systems may help to explain these comparative findings. Results appear consistent with the ‘market integrity hypothesis’ postulating that reliance on publicly observable fundamentals is higher when insider trading is lower.     

Attitudes and related perceptions about product placement: a comparison of Finland,Italy and the United States

The primary goal of our study is to explore cross-national differences in attitudes and perceptions about product placements, after investigating measurement invariance. Our cross-national focus includes three countries that have not been compared previously: Finland, Italy and the USA, which differ significantly in terms of the evolution/maturity of product placement markets, regulatory structures and cultural contexts. Motivated by earlier studies, we investigate the cross-national measurement invariance of scales to measure four research constructs related to the product placement domain (attitude toward credibility of advertising, attitude toward advertising-in-general, attitude toward placement-in-general and attitude toward regulation of placements). Our research also extends earlier work focused on similar constructs from a cross-national perspective. Results from multi-group analyses using a structural equation modeling approach indicate important and statistically significant differences in latent means between the three countries for all four constructs of research interest. Substantive explanations of these differences and their implications for future practice and research are discussed.     

Mobile Phones and Radios: Effects on Transactions Costs and Market Participation for Households in Northern Ghana

The literature on agricultural markets suggests that transactions costs are the main obstacles preventing households from participating in agricultural markets. We examine the impact of the recent massive penetration of information communication technologies (ICTs), particularly mobile phones and radios, in developing countries to investigate the role of information in economic transactions and participation in food crop markets. To fully capture market participation behaviours, the current theoretical framework on market participation and transactions costs is extended to include those households that sell and buy in the same time period. We correct for endogeneity and selectivity throughout our models. We used a novel dataset of 393 households in northern Ghana with detailed information on market transactions and ICTs usage. Results show that receiving market information via mobile phones has a positive and significant impact on market participation, with a greater impact for households with a surplus of food crops. We find that radios have a larger impact on the quantity traded. This may reflect the nature of mobile phones in reducing searching costs, whereas radios provide an updated and regular flow of information which affects the pattern of crops consumed and sold. We also emphasise that the most significant factor is how ICTs are used, rather than their ownership.     

A metacultural approach to predicting self-employment across the globe

Drawing from neo-institutional theory, we examine the relationship between preference for entrepreneurship and actual entrepreneurship behavior across multiple countries and cultures. We elucidate how multiple societal-level cultural models, namely Hofstede, Global Leadership and Organizational Behavior Effectiveness (GLOBE), and Schwartz affect the individual-level process connecting expressed preference for self-employment and actual behavior. Our hypotheses were tested using a multilevel technique on a sample of 20,755 individuals across 24 countries. The findings indicate that the moderating effect of predominant cultural cognition is partially supported. Contributions and implications for theory and practice are also discussed.

Semi-unionized bargaining with endogenous membership and management opposition

This paper develops a model of open shop unions and efficient bargain, in which there is a social custom to unionize and the firms can pay wage premiums to dissuade union membership. If firms actively oppose unions, the union density turns out to be affected by changes of the product price and the reservation wage, and it is not always positively correlated with the workers' income share. Moreover, the model provides a rationale for higher union density in centralized as opposed to decentralized bargaining systems.I would like to thank Robert Boyer, Hans Peter Grüner, Roger Guesnerie, and two referees for helpful comments and suggestions. All remaining errors are mine. Financial support from the Commission of the European Communities (SPES-915028) is gratefully acknowledged.     

The Rise and Likely Fall of the German Income Tax, 1958-2005

Data from official statistics and tax laws are exploited todescribe fifty years of income taxation in Germany, with a focuson its role as a fiscal and distributive tool. The temporalpattern that emerges from the data is one of a golden age ofthe German income tax, followed by a slow shift towards a majorcrisis. The turning point on the income-tax path seems to haveoccurred in 1986. I put forward the thesis that this downturnwas the outcome of a long-term change in the balance of politicalpower. That change is probably rooted in structural breaks thatoccurred in the German economy during the 1970s and early 1980s.(JEL D31, D72, H23}.     

Hormone beef, chlorinated chicken and international trade

We study international trade in innovative goods subject to uncertain consumer health effects. Such goods are often at the center of international trade disputes. We show that an interesting form of protectionism may arise because of scientific uncertainty. A free-riding effect is identified, implying more conservative behavior by countries. We also study the role of producers (lobbies) in providing valuable information, finding that the innovative lobby has an advantage in providing information as compared with the lobby producing the ‘traditional’ good. Moreover, lobbies disclose more information when the health effects are long lasting.
