Reforming the German Local Business Tax: Lessons from an International Comparison and a Microsimulation Analysis

The local business tax as the main revenue source of local governments in Germany has been under extensive debate for decades. Proposals for reform range from a pure profit tax to an origin-based value-added tax. Local business taxation systems in OECD countries actually represent the whole spectrum between these two extremes. We use a newly developed microsimulation model for the business sector in ...

Only the Congruent Survive: Personality Similarities in Couples

Numerous studies proved that people tend to select partners that are similar to them with regard to many social and psychological variables. Even though this effect was also found for personality, results are inconsistent and reveal convergence coefficients ranging from negative over zero- to positive correlations. The present study thus aims to investigate personality congruence between spouses and ...

Early Childhood Education and Care in Germany: The Status Quo and Reform Proposals

The Dynamics of European Inflation Expectations

We investigate the relevance of Carroll's sticky information model of inflation expectations for four major European economies (France, Germany, Italy and the United Kingdom). In contrast to the most rational expectation models, households in the sticky information environment update their expectations occasionally rather than instantaneously due to the costs of acquiring and processing information. ...

Redistributive Impacts of Government and Private Household Activities: Trends in Equivalized Household Net Incomes and Intra-household Earnings in Germany, 1985-2005

A Complementarity Model for the European Natural Gas Market

In this paper, we present a detailed and comprehensive complementarity model for computing market equilibrium values in the European natural gas system. Market players include producers and their marketing arms which we call "traders", pipeline and storage operators, marketers, LNG liquefiers, regasifiers, tankers, and three end-use consumption sectors. The economic behavior of producers, traders, ...

Human Capital Externalities: Evidence from the Transition Economy of Russia

The paper tests for the existence of human capital externalities using a micro-level approach: the Mincerian wage regression augmented with the average level of education in cities. To solve identification problems arising from the endogeneity of average education, the study exploits a natural experiment provided by the process of economic transition: average education at the end of communism can be ...

Political Patronage in Ukrainian Banking

This paper empirically investigates the link between political patronage and bank performance for Ukraine during 2003Q3-2005Q2. We find significant differences between politically affiliated and non-affiliated banks. The data suggest that affiliated banks have significantly lower interest rate margins and increase their capitalization. Furthermore, we show that the level of activity of affiliated deputies ...

Regional Income Stratification in Unified Germany Using a Gini Decomposition Approach

Using representative micro data from the German Socio-Economic Panel Study (SOEP), this paper delivers new insights into the development of income inequality and regional stratification in Germany after unification. This paper applies a new method for detecting social stratification by a decomposition of the Gini index that yields the obligatory between- and within-group components as well as an 'overlapping' ...

Electricity Wholesale Market Prices in Europe: Convergence?

This paper tests the hypothesis that the ongoing restructuring process in the European electricity sector has led to a common European market for electricity. Based on a Principal Component Analysis (PCA) of wholesale electricity prices in 2002-2006, we reject the assumption of full market integration. For several pairs of countries, the weaker hypothesis of (bilateral) convergence is accepted based ...

Voting, Inequality and Redistribution

This paper surveys models of voting on redistribution. Under reasonable assumptions, the baseline model produces an equilibrium with the extent of redistributive taxation chosen by the median income earner. If the median is poorer than average, redistribution is from rich to poor, and increasing inequality increases redistribution. However, under different assumptions about the economic environment, ...

On the Choice of Public Pensions When Income and Life Expectancy Are Correlated

The paper presents a model where public pensions are determined by majority voting. Voters differ by age and income. Moreover, life expectancy increases with income. Depending on the strength of the link between contributions and benefits, and the relationship between income and life expectancy, individually optimal tax rates may increase or decrease with income. If they decrease, high tax rates are ...

Central versus Local Education Finance: A Political Economy Approach

This paper models voters' preferences over central versus local education policies when there are private alternatives. Education is financed by income taxes and individuals are mobile between communities. Public education levels are chosen by majority vote. Contrary to conventional wisdom, centralisation may benefit the rich and poor, while the middle class prefer decentralised education. The model ...

Measuring Ethnic Identity and Its Impact on Economic Behavior

This article advocates for a new measure of the ethnic identity of migrants, models its determinants, and explores its explanatory power for economic performance. The ethnosizer, a measure of the intensity of a person's ethnic identity, is constructed from information on the following elements: language, media, ethnic self-identification, ethnic networks, and residency plans. The two-dimensional concept ...

Life Satisfaction Shows Terminal Decline in Old Age: Longitudinal Evidence from the German Socio-Economic Panel Study (SOEP)

Longitudinal data spanning 22 years, obtained from deceased participants of the German Socio-Economic Panel Study (SOEP; N = 1,637; 70- to 100-year-olds), were used to examine if and how life satisfaction exhibits terminal decline at the end of life. Changes in life satisfaction were more strongly associated with distance to death than with distance from birth (chronological age). Multiphase growth ...

Carbon Capture and Storage: Settling the German Coal vs. Climate Change Dispute?

Technological Change and Transition: Relative Contributions to Worldwide Growth during the 1990s

In this paper we use the Kumar and Russell [American Economic Review (2002) Vol. 92, pp. 527-548] growth-accounting procedure to examine cross-country growth during the 1990s. Using a data set comprising developed, newly industrialized, developing and transitional economies, we decompose the growth of output per worker into components attributable to technological catch-up, technological change and ...

Overtime Work as a Signaling Device

This paper provides an explanation for the empirically proven relationship between overtime and future benefits. We suggest an internal signaling model, in which a worker signals his value to the employer by supplying unpaid overtime. In our empirical analysis, we examine whether overtime has in fact a signaling component. Variations in collectively bargained hours between industries are exploited, ...

Leistungs- oder Bedarfsgerechtigkeit? Über einen normativen Zielkonflikt des Wohlfahrtsstaats und seiner Bedeutung für die Bewertung des eigenen Erwerbseinkommens

Der Beitrag analysiert den Zielkonflikt zwischen Leistungs- und Bedarfsgerechtigkeit in modernen Wohlfahrtsstaaten und das fundamentale Problem, weshalb die Abgabenund Steuerlast von den Bürgern akzeptiert wird. Es wird die Frage beantwortet, inwieweit ein auf der Makroebene der Gesellschaft bestehendes Steuerungsproblem moderner Wohlfahrtsstaaten auch in der individuellen Wahrnehmung Gerechtigkeitsprobleme ...
