Incomes and Inequality in the Long Run: The Case of German Elderly

Abstract. We use German Sample Survey income data to examine the income distribution for elderly individuals during the period from 1978 to 2003. The elderly population, defined as people of age 55 and older, is decomposed by people resident in the Old and New Federal States. Further, we distinguish between persons receiving old‐age pensions and persons who do not. Inequality estimates are decomposed by income components, and the bootstrap method is used to test for statistical significance of results.     

Price transmission and local market power: empirical evidence from the Austrian gasoline market

We analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics (speed and asymmetry of price transmission) using data for a large number of individual gasoline stations in Austria. Specific attention is paid to threshold effects in price adjustment. Our results clearly suggest that the speed of price transmission between the Brent crude oil index and retail diesel prices is higher in a more competitive environment. While evidence on the relationship between local market power and asymmetries in the speed of price adjustment is mixed, our findings regarding asymmetries in price thresholds are clear: in regions where competition from neighbouring rivals is weak and/or consumers’ price elasticity of demand is low (stations located on the highway), positive thresholds significantly exceed negative ones, which corresponds to the ‘rockets and feathers phenomenon’. As expected, we observe that prices are lower in more competitive local markets.     

Non-cooperative and cooperative policy reforms under uncertainty and spillovers

When countries need to implement costly economic policy reforms, these often imply uncertainties about their effectiveness for the home country and their spillovers to other countries. We develop a model to show that under these circumstances countries implement too few or too many policy reforms. From a social perspective, too many reforms follow if the spillover effects of reforms become sufficiently uncertain. Since centralization of policies to correct inefficient policies is often not possible, we look for alternative instruments that can restore the efficient level of reforms. We compare subsidizing reform efforts with insuring against bad outcomes, and argue that subsidies are advantageous in terms of requiring less information for implementation.     

Discrete and Continuous Representations of Unobserved Heterogeneity in Choice Modeling

We attempt to provide insights into how heterogeneity has been and can be addressed in choice modeling. In doing so, we deal with three topics: Models of heterogeneity, Methods of estimation and Substantive issues. In describing models we focus on discrete versus continuous representations of heterogeneity. With respect to estimation we contrast Markov Chain Monte Carlo methods and (simulated) likelihood methods. The substantive issues discussed deal with empirical tests of heterogeneity assumptions, the formation of empirical generalisations, the confounding of heterogeneity with state dependence and consideration sets, and normative segmentation.

A Head-to-Head Comparison of Augmented Wealth in Germany and the United States*

We examine the composition of augmented household wealth (i.e., the sum of net worth and pension wealth) in the United States and Germany. Pension wealth makes up a considerable portion of household wealth, of about 48 percent in the United States and 61 percent in Germany. When pension wealth is included in household wealth, the Gini coefficient falls from 0.889 to 0.700 in the United States, and from 0.755 to 0.508 in Germany. If the wealth shares in Germany were the same as in the United States, this would lead to a 12.6 percent increase in the Gini coefficient in the augmented wealth distribution in Germany.     

Two-step QCA revisited: the necessity of context conditions

Quality & Quantity - The so-called two-step QCA approach as formulated by Schneider and Wagemann (Eur J Polit Res 45(5):751–786, 2006) proposes a separation of conditions into two...
