In dem vorliegenden Artikel werden ausgewählte theoretische und empirische Aspekte des Zusammenhangs zwischen Existenzgründungen, staatlichem Handeln und Beschäftigung diskutiert. Dabei wird die Frage, ob Existenzgründungen zusätzliche Beschäftigung schaffen überwiegend aus einer...

We use a unique matched tax return-financial statement data set to examine the magnitude and sources of book-tax differences in Germany. For the first time, the data set enables us to evaluate the extent to which financial and tax accounting differ in Germany in the most accurate manner. Despite...

Previous estimates of inequality of opportunity (IOp) are lower bounds because of the unobservability of the full set of endowed characteristics beyond the sphere of individual responsibility. Knowing the true size of unfair IOp, however, is important for the acceptance of (some) inequality and...

Does the supply of a welfare state create its own demand? Many economic scholars studying welfare arrangements refer to Say's law and insinuate a self-destructive welfare state. However, little is known about the empirical validity of these assumptions and hypotheses. We study the dynamic effect...

In 2006, the reform of the German fiscal constitution realigned legislative powers between the federal and the state governments. Since 2007, the German state governments have been allowed to design real estate transfer tax rates. We investigate whether government ideology predicts the levels...

We consider an economy characterised by involuntary unemployment among low skilled workers, and investigate the implications for employment and income of welfare schemes often advocated as less distortionary. We show that reducing unemployment benefits in favour of income subsidies (social...

This paper analyzes the impact of aging on capital accumulation and welfare in a country with a sizable unfunded social security system. Using a two-period overlapping generation model with potentially endogenous retirement decisions, the paper shows that the type of aging, i.e. declining...

This paper examines how restrictions on the tax-deductibility of interest cost affect location choices of multinational corporations (MNCs). Many countries have introduced so-called thin-capitalization rules (TCRs) to prevent MNCs from shifting tax base to countries with lower tax rates. As of...

This paper analyzes the impact of demographic aging on capital accumulation and welfare in economies with unfunded pensions. Using a two-period overlapping generation model with potentially endogenous retirement decisions, it shows that both the type of aging, i.e. declining fertility or...

The German government provides discretionary investment grants to structurally weak regions to reduce regional disparities. We use a regression discontinuity design that exploits an exogenous discrete jump in the probability of receiving investment grants, to identify the causal effects of the...
