We relax the common assumption of homogeneous beliefs in principal-agent relationships with adverse selection. Principals are competitors in the product market and write contracts also on the base of an expected aggregate. The model is a version of a cobweb model. In an evolutionary learning...

Entry in a homogeneous Cournot-oligopoly is excessive if there is business stealing. This prediction assumes that production costs reduce profits and welfare equally. However, this need not be the case. If there is asymmetric information, suppliers or employees can utilize their superior...

Do trade unions benefit from economic crises by attracting new members among workers concerned about job security? To address this question, we provide a comprehensive empirical investigation based on panel data from Germany, where workers individually decide on their membership. We analyse...

This paper examines the role of individuals' emotions in determining their concerns about international migration. For the empirical analysis, we exploit the previously less explored information in the German Socio-Economic Panel (SOEP) data on individuals' negative emotions, e.g., anger, fear,...

We analyse in what way co-determination affects non-compliance with the German minimum wage, which was introduced in 2015. The Works Constitution Act (WCA), the law regulating co-determination at the plant level, provides works councils with indirect means to ensure compliance with the statutory...

We analyse the implications of habit formation relating to wages in a multi-period efficiency-wage model. If employees have such preferences, their existence provides firms with incentives to raise wages and reduce employment over time. Greater intensity does not necessarily have the same...

Trade unions distort a profit-maximising firm's input choice. The nature of the resulting inefficiency depends on whether there are wage negotiations or there is efficient bargaining. Moreover, trade unions redistribute income and thereby affect welfare. If firms also pursue Corporate Social...

Employment protection legislation may affect the degree of substitutability among different types of labour contracts by changing the individuals sorting into jobs and firms screening in and out jobs. Using administrative data, we document this substitutability in the context of a labour market...

In many countries, the termination of employment contracts has to be either on employer initiative or on employee initiative. In 2008, the French government introduced a change in doctrine: it became possible to terminate employment contracts by mutual consent at a lower cost. We show that the...

If individuals join a trade union their utility should increase. Therefore, union members can be expected to exhibit higher job satisfaction than comparable non-members. This expectation is not consistent with empirical findings. The evidence sometimes indicates that union members have lower job...
