This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. Resources allocated to R&D are limited and should therefore be used efficiently given the institutional and legal constraints. This paper presents efficiency scores based on an...

This paper analyzes research efficiency at the industry level in manufacturing for 13 European member and four nonmember countries during 2000 and 2004. A unique dataset was compiled that matches patent applications at the European Patent Office (EPO) to industry-specific R&D inputs from EU...

Does a country's level of unemployment have an impact on the long-run growth rate? Incorporating unemployment into a generalised Solow-type growth model yields some answers. In the traditional Solow model, unemployment has no long-run influence on the growth rate and the level of productivity....

Technological changes in renewable energy technologies play an important role in the context of climate change as they contribute to a reduction of technology costs and lead to an increasing market penetration of emission reducing technologies. This paper provides a comprehensive literature...

To measure income inequality with right censored (topcoded) data, we propose multiple imputation for censored observations using draws from Generalized Beta of the Second Kind distributions to provide partially synthetic datasets analyzed using complete data methods. Estimation and inference...

We analyse the convergence and heterogeneity of living standards between East and West Germany since unification. Based on data from the German Socio-Economic Panel (GSOEP), we compare total individual income of permanent adult residents, including retirees and the unemployed, of East and West...

There is by now a lot of evidence showing a sharp increase in cross-sectional wage and earnings inequality during the 2000s in Germany. Our study is the first to decompose this cross-sectional variance into its permanent and transitory parts for years beyond 2000. Using data from the German...

Using representative survey data from the German Socio-Economic Panel Study (SOEP) for 2006, we show that the magnitude of such health inequality measures as the concentration index (CI) depends crucially on the underlying health measure. The highest degree of inequality is found when...

We suggest to use information from the state register of personal cars as an alternative indicator of economic inequality in countries with a large share of shadow economy. We illustrate our approach using the Latvian pool of personal cars. Our main finding is that the extent of household...
