This paper suggests a new approach for centrality measures for general (weighted) networks taking into account the importance for cohesion and relative power of connections. While existing literature either ignores the importance for cohesion or measures it by analyzing consequences arising from...

When workers send applications to vacancies they create a bipartite network. Coordination frictions arise if workers and firms only observe their own links. We show that those frictions and the wage mechanism are in general not independent. Only wage mechanisms that allow for ex post competition...

We consider a co-evolutionary model of social coordination and network formation where agents may decide on an action in a 2x2 - coordination game and on whom to establish costly links to. We fi nd that a payo ff dominant convention is selected for a wider parameter range when agents may only...

We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model may state...

We conducted an experiment on the nature of income sharing within 95 established couples in Germany. In a first step, the partners revealed their individual preferences by making consumption choices independently. In a second step, decisions were taken jointly over five different rounds with...

We use the Shapley value and the nucleolus to analyze the impact of three controversial pipeline projects on the power structure in the Eurasian trade of natural gas. Two pipelines, `Nord Stream' and `South Stream', allow Russian gas to bypass transit countries, Ukraine and Belarus. The third...

We study the impact of the liberalization of EU natural gas markets on the balance of power between `local champions', customers, and outside producers. We distinguish between two steps of the reform: 1. opening access to transit pipes and 2. opening access to distribution systems, hence...

We show theoretical and experimental results that demonstrate the potential of transparency to influence committee decision making and deliberation. We present a model in which committee members have career concerns and unanimity is needed to change the status quo. We study three scenarios -...

Why do some economic systems depend on bank financing while others rely on capital markets and bond financing? We propose a political economy model in which elites favor a bank-based system, which increases their rents due to reduced competition. If suffrage is restricted to the elite, this will...

This paper investigates how heterogeneity in contestants' investment costs affects the competition intensity in a dynamic elimination contest. Theory predicts that the absolute level of investment costs has no effect on the competition intensity in homogeneous interactions. Relative cost...
