It is noted that modern economics cannot decide which economic system is the best way of organizing production. In particular, support is given to Nelson (1981) who claims that modern economics does not provide any substantial argument in favor of private enterprise being the best. However,...

Green certificates are the main instrument for promoting renewable electricity (RES-E) in Sweden. But certificates cover only a limited share of total RES-E production. Under partial coverage, crowding out may arise whereby costly new RES-E replaces inexpensive old RES-E. Granting certificates...

There are several theoretical accounts of public sector outsourcing. We note that leading theories give different predictions of the influence of political variables and test the predictions on a Swedish data set in which outsourcing varies between municipalities and over time as well as between...

The theory of the firm suggests that firms can respond to poor contract enforcement by vertically integrating their production process. The purpose of this paper is to examine whether firms' integration opportunities affect the way institutions determine international trade patterns. We find...

The make-or-buy decision is analyzed in a simple framework combining contractual incompleteness with the existence of imperfect but contractible performance measures. Contractual incompleteness gives rise to two regimes, identified with make and buy. The performance measure on which...

This paper deals with the interplay between economic incentives and social norms in firms. We outline a simple model of team production and provide preliminary results on linear incentive schemes in the presence of a social norm that may cause multiple equilibria. The effect of the social norm...

The make-or-buy decision is analyzed in a three-layer principal-management-agent model. There is a cost-saving/quality tradeoff in effort provision. The principal chooses between employing an in-house management and contracting with an independent management; the cost-saving incentives facing...

I analyze renewable electricity policy in a multinational electricity market with transmission investment. If national policy makers choose support schemes to maximize domestic welfare, then a trade policy motive arises operating independently of any direct benefit of renewable electricity. The...
