We use a new micro data set that covers all oil fields in the world to estimate a stochastic industry-equilibrium model of the oil industry with two alternative market structures. In the first, all firms are competitive. In the second, OPEC firms act as a cartel. This effort is a first step...

We use a new micro data set to estimate a stochastic industry-equilibrium model of the oil industry. This effort is a first step towards studying the importance of ongoing structural changes in the oil market in a general-equilibrium model of the world economy. We analyze the impact of the...

The low mobility of people in Europe is considered a problem for adjustment to asymmetric shocks and regional convergence in the European Monetary Union. We suggest a complement to the traditional migration theories, the insider advantages approach to explain why most Europeans prefer to stay....

Was bestimmt das individuelle Wanderungsverhalten? Herkömmliche migrationsökonomische Theorieansätze greifen oft zu kurz und überschätzen deshalb die grenzüberschreitenden Wanderungsbewegungen bei weitem. Dieses Diskussionspapier stellt die bisherige Optik auf den Kopf und sucht nach...

The notion of social entrepreneurship has gained increasing recognition in the last years, both as an increasingly visible mode of economic action, and as an important policy tool. The paper outlines a typology that departs from a Schumpeterian view of entrepreneurship, that centers on the...

The first part of the paper reports the results from a sequence of laboratory experiments comparing the bidding behavior for multiple contracts in three different sealed bid auction mechanisms; first-price simultaneous, first-price sequential and first-price combinatorial bidding. The design of...

This paper considers the social costs implied by inefficient allocation of contracts in a first price, sealed bid procurement auction with asymmetric bidders. We adopt a constrained (piecewise linear) strategy equilibrium concept and estimate the structural parameters of the bidders'...
