In this paper we focus on proximity as one of the main determinants of international collaboration in pharmaceutical research. We use various count data specifications of the gravity model to estimate the intensity of collaboration between pairs of countries as explained by the geographical,...

Credit reporting systems are an important ingredient for financial markets. These systems are based upon the unique identification of borrowers, which is enabled if a compulsory identification system exists in a country. We present evidence derived from difference-in-difference analyses on the...

On 05 December 2010, the Renewable Energy Directive (RED) came into force in the EU. Member States are still working to fully transpose the Directive into national law and establish a framework for achieving their legally binding greenhouse gas (GHG) emission reductions. However, governments got...

A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some...

Knowledge production and scientific research have become increasingly more collaborative and international, particularly in pharmaceuticals. We analyze international research networks on the country level in different disease groups. Our empirical analysis is based on a unique dataset of...

In this paper, we focus on the analysis of individual decision making for the formation of social networks, using experimentally generated data. We first analyse the determinants of the individual demand for links under the assumption of agents' static expectations. The results of this exercise...

Anecdotal evidence suggests that journalists and bureaucrats in some countries are killed when they try to blow the whistle on corruption. We demonstrate in a simple game-theoretical model how murders can serve as an enforcement mechanism of corrupt deals under certain regime assumptions....

Transparency in teams can induce cooperation. We study contribution decisions by agents when previous decisions can be observed. We find that an information chain, in which each agent directly observes only the decision of her immediate predecessor, is at least as effective as a...

The winner's curse is a well-known deviation from rational self-interest in decision-making under asymmetric information. Yet, most prominent explanations for the curse have experimentally been ruled out so far. In particular, the curse did neither seem to emanate from a lack of experience with...

Entrepreneurs are found to have balanced skill sets and most have worked in small firms before starting their own business. In light of this, we compare the skill sets of employees working in businesses of different size to the skill sets of entrepreneurs using a rich data set on the applied...
