RELATIVE INEQUALITY AND POVERTY IN GERMANY AND THE UNITED STATES USING ALTERNATIVE EQUIVALENCE SCALES

We use data from the Luxembourg Income Study to show the sensitivity of measures of relative economic well-being of persons in the U.S. and Germany using official equivalence scales and consumption-based country-specific equivalence scales developed for the two countries. Overall inequality and poverty levels are found not to be sensitive to the equivalence scale used. However, the official German equivalence scale yields quite different results from the others with respect to the relative income and poverty levels of vulnerable groups within the population, especially older single people.     

The multiresolution histogram

We introduce a new method for locally adaptive histogram construction that doesn’t resort to a standard distribution and is easy to implement: the multiresolution histogram. It is based on aL ₂ analysis of the mean integrated squared error with Haar wavelets and hence can be associated with a multiresolution analysis of the sample space.     

Versicherungsmedizinische Risikobeurteilung von pathologischen Leberwerten und aktuellen Entwicklungen bei der chronischen Hepatitis

Alcoholic liver disease, non alcoholic fatty liver and chronic viral hepatitis have a high prevalence in the German population. They are associated with significantly increased occupational disability and mortality. Elevated levels of GGT or ALT can be found in about 10 % of the general population. Attempts to identify an underlying diagnosis often remain unsuccessful. In selected cases CDT can be helpful to confirm or rule out suspected alcohol-abuse. Recent studies showed that non alcoholic steatohepatitis (NASH) is a potentially severe complication of diabetes and its metabolic precursors. Treatment options for chronic viral hepatitis get more and more sophisticated, but the rates of sustained cure are still unsatisfactory, especially in hepatitis B with negative HBe-antigen and the hepatitis C genotypes 1, 4 and 5. Life long suppression of HBV replication by nucleoside analogues seems to prevent liver cirrhosis, but may become a great burden on health costs. The risk assessment of HBV carriers and of patients with successfully treated viral hepatitis should rely on the expertise of experienced physicians.     

Credit constraints and exports: evidence for German manufacturing enterprises

This study uses newly available enterprise-level data for firms from manufacturing industries in Germany to test for the link between credit constraints, measured by a credit-rating score from the leading credit-rating agency Creditreform, and exports. In line with hypotheses from a theoretical model, we find a positive link between a better credit-rating score of a firm and both the probability that the firm is an exporter and a higher share of exports in total sales. This link, though statistically highly significant, is not very strong from an economic point of view. While empirical evidence for the hypothesis that credit-constrained firms are less likely to start to export is, at best, weak, we find no evidence for a statistically significant difference in credit-rating scores between firms that stopped to export and firms that continued to export.
