We propose a generalized estimating equations approach to the analysis of the mean and the covariance structure of a bivariate time series process of panel data with mixed continuous and discrete dependent variables. The approach is used to jointly analyze wage dynamics and the incidence of...

The 1/n problem potentially limits the effectiveness of profit sharing in motivating workers. While the economic literature suggests that reciprocity can mitigate this problem, it remains silent on the optimal degree of reciprocity. We present a representative model demonstrating that...

The European Union's strategy to raise employment is confronted with very low work participation among many minority ethnic groups, in particular among immigrants. This study examines the potential of immigrants' identification with the home and host country ethnicity to explain that deficit. It...

It is known that small firms rely mainly on the CEO's individual knowledge for developing innovations. Recent work suggests that this approach is inefficient since it underutilizes other employees' knowledge. We study to which extent using CEOs, managers and non-managerial employees' ideas...

Early retirement options are usually targeted at employees at risk of not reaching their regular retirement age in employment. An important at‐risk group comprises employees who have worked in demanding jobs for many years. This group may be particularly negatively affected by the abolition of...

Using unique survey data from the German Socio-Economic Panel, this study examines the influence of reciprocal inclinations on workers' sorting into codetermined firms. Employees with strong negative reciprocal inclinations are more likely to work in firms with a works council while employees...

When possible income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour or against a certain policy. Quantitative ex-ante evaluations of the effect of certain tax reform options on entrepreneurship based on microeconometric research have not...

The determinants of migrants' remittances are the subject of this study based on German SOEP data (2001-2006). In contrast to previous studies we analyze the motives for remittances not only for foreigners but also for the broader group of individuals with a personal migration background. Major...

This paper investigates the factors that explain the level and dynamics of manufacturing firm productive efficiency. In our empirical analysis, we use a unique sample of about 39,000 firms in 256 industries from the German Cost Structure Census over the years 1992-2005. We estimate the...

In response to increasing health expenditures and a high number of physician visits, the German government introduced a copayment for ambulatory care in 2004 for individuals with statutory health insurance (SHI). Because persons with private insurance were exempt from the copayments, this health...
