Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970-2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry-specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross-sectional heterogeneity is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear-cut impact.

This study investigates competition between health insurance companies under different financing regulations. We consider two alternatives advanced in recent German healthcare reform discussions: competition by contribution rates (health contributions) and by fees (health premia). We find that contribution rate competition yields lower company profits and higher consumer welfare than premia competition when switching between insurance companies is costly.

In a centralized federation, in which tax rates and taxation rules are set by the federal government, manipulating the thoroughness of tax auditing and the effectiveness of tax collection could be attractive for regional authorities. In this article, we test for strategic tax collection empirically using data of the Russian Federation. Russia’s regional authorities in the 1990s have always been suspected of tax auditing manipulations in their favour. However, in the 2000s, increasing bargaining power of the centre seems to induce tax collection bodies in the regions to manipulate tax auditing in favour of the federal centre. Our findings confirm the existence of strategic tax collection for the Yeltsin period; the results for the Putin period are however ambiguous.

This paper analyzes differences in inequality perceptions, distributional norms, and redistributive preferences between East and West Germany. As expected, there are substantial differences with respect to all three of these measures. Surprisingly, however, differences in distributional norms are much smaller than differences with respect to inequality perceptions or redistributive preferences. Moreover, individuals from East Germany tend to be more supportive of state redistribution and progressive taxation and they are less likely to have a conservative political orientation. I finally show that a substantial part of these differences in political preferences can be explained by underlying differences in redistributive preferences.
