We introduce a one-parameter class of individual deprivation measures. Motivated by a suggestion of Runciman, we modify Yitzhaki's index by multiplying it by a function that is interpreted as measuring the part of deprivation generated byan agent's observation that others in his reference group move on to a higher level of income than himself. The parameter reflects the relative weight given to these ...
This paper investigates changing attitudes towards the euro over time in Germany using longitudinal micro-data from the German Socio Economic Panel Study. We observe that a large part of the German population was worried about the new currency both before and after its introduction. Social psychological theories provide insight into these attitudes. Concerns regarding the euro are apparently connected ...
Estimates of the labour supply effects of recent UK reforms in the area of direct taxes and benefits show that policy can have significant influence on the level of employment. We confirm this in a simulation of an in-work support system introduced into the German tax and benefit system. Our simulation results suggest that introducing in-work tax credits in Germany would increase the employment of ...
The premium rates paid for statutory health insurance in Germany play a key role in the competition among health care funds. With the most recent health care reform (GKV-Wettbewerbsstärkungsgesetz GKV-WSG), a range of new products have been introduced that could erode the advantageous selling proposition of the premium rates. In addition to the pure monetary incentive to change health insurance provider, ...
We use data from the German Socio-Economic Panel and the British Household Panel Survey to estimate the extent of intergenerational economic mobility in a framework that highlights the role played by assortative mating. We find that assortative mating plays an important role. On average about 40-50% of the covariance between parents' and own permanent family income can be attributed to the person to ...
This study applies non-parametric and parametric tests to assess the efficiency of electricity distribution companies in Germany. Traditional issues in electricity sector benchmarking are addressed, such as the role of scale effects and optimal utility size, as well as new evidence specific to the situation in Germany. Labour, capital, and peak load capacity are used as inputs, and units sold and the ...
