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...

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...

The interaction between monetary and fiscal policy and the associated uncertainty about this interaction have been put on center stage by the recent financial crisis and the associated recession. In our model agents learn about both fiscal and monetary policy rules via the Kalman Filter. In...

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 find that a payoff dominant convention is selected for a wider parameter range when agents may only...

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...

Das 1. Symposium für Ökonomie im Gartenbau fand am 27. November 2013 in der Paulinerkirche in Göttingen statt. Es wurde als Kooperation der Georg-August-Universität Göttingen, des Thünen- Instituts für Betriebswirtschaft und des Agrarkompetenznetzes WeGa durchgeführt. Die Veranstaltung...

We study strategic communication between a Sender and Receiver who are both uncertain about their preferred actions. The Sender observes noisy signals about both players' ideal policies and then communicates with the Receiver. Even though Sender and Receiver disagree about ideal policies as a...

In this paper, we analyse the effects of objective and subjective knowledge about monetary policy, as well as the information search patterns, of German citizens on trust in the ECB. We rely on a unique representative public opinion survey of German households conducted in 2011. We find that...

This paper considers investments in cost-reducing technology in the context of contributions to climate protection. Contributions to mitigating climate change are analyzed in a two-period model where later contributions can be based on better information, but delaying the contribution to the...
