Using micro-level panel data of about 35,000 firms from the German Cost Structure Census, we analyze the differences of technical efficiency across industries. Technical efficiency is estimated by firms? fixed effects. One striking result is that the distribution of technical efficiency across...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

We estimate a dynamic structural life-cycle model of employment, non-employment and retirement that includes endogenous accumulation of human capital and intertemporal non- separabilities in preferences. Additionally, the model accounts for the effect of the tax and transfer system on work...

To quickly adapt to technological change and developments, and thus remain competitive, firms increasingly resort to the use of external technology. This paper investigates whether and to what extent the acquisition of external disembodied technology affects the efficiency and productivity in...

Using firm-level panel data from the German cost structure survey over the period 1992 to 2000, our empirical analysis shows that firms that increased material inputs relative to internal labor costs performed better in terms of gross operating surplus than other firms. However, firms that...

Estimating labor supply functions using a discrete rather than a continuous specification has become increasingly popular in recent years. On basis of the German Socioeconomic Panel (GSOEP) I test which specification of discrete choice is the appropriate model for estimating labor supply: the...

In the year 2000, the German government passed the most ambitious tax reform in postwar German history aiming at a significant tax relief for households. Drawing on data of the GSOEP, we analyze the distributional and fiscal effects of the tax reform. Our analysis employs microsimulation...

This paper analyzes the distribution of technical efficiency within manufacturing industries. Using a representative sample of 35,000 firms in 255 industries of the German cost structure census, technical efficiencies are estimated by applying a deterministic frontier production function with...
