We develop a social network model of occupational segregation between different social groups, generated by the existence of positive inbreeding bias among individuals from the same group. If network referrals are important for job search, then expected homophily in the contact network structure...

A coalitional matching is a two-sided matching problem in which agents on each side of the market may form coalitions such as student groups and research teams who - when matched - form universities. We assume that each researcher has preferences over the research teams he would like to work in...

In this paper we develop a model to analyze, in a dynamic framework, how countries join international environmental agreements (IEAs). In the model, where countries suffer from the same environmental damage as a result of the total global emissions, a non-signatory country decides its emissions...

The analysis finds that in addition to U-shaped paths of environmental quality arising for growth in income per capita, growth in population can also produce socially efficient patterns that are U-shaped. Sufficient conditions for both types of paths are identified for a range of models and...

Cost-benefit analyses require comparing costs and benefits that occur at different points in time. Doing so, however, creates conflicts between short-term considerations a discounting scheme has to be consistent with observed behaviours and long-term ethical issues a discounting scheme must not...

We analyze a model of price competition á la Bertrand in a network environment. Firms only have a limited information on the structure of network: they know the number of potential customers they can attract and the degree distribution of customers. This incomplete information framework...

Innovationen sind das Kernelement des Überlebens und der Positionierung von Volkswirtschaften, da sie zur Befriedigung der Marktbedürfnisse beitragen. Vor dem Hintergrund knapper Ressourcen werden jedoch regelmäßig nur die Innovationen realisiert, die aus einer betriebswirtschaftlichen...

Bargaining between different groups, which differ in objectives, preferences and interests, is at the core of political decision-making. Yet, it is logical to presume that negotiations involving more parties will lead to inertia and a slow pace in the legislative process. According to this...
