Accomodated here is a measure space of economic agents, each regarded as a profit maximizing producer, each endowed with his technology and resource bundle. Pooling of private endowments generates a cooperative game with side payments.

Retail chains are observed in many industries. The question addressed here is whether retail chains can exploit buyer power by excluding some brands. In a theoretical model with two differentiated producers and a single retailer, we show that a retailer will require exclusivity (exclude a brand)...

This paper examines the empirical importance of randomisation bias in a Norwegian randomised field trial on a rehabilitation programme for sick listed worders. Inclusion of participants in the trial was base on information obtained from administrative social insurance records. Professional...

This paper examines the causes of agricultural land expansion and deforestation in Tanzania. In the theoretical section, two different -and partly contradicting- sets of hypotheses are outlined.

We provide a new and simple convergence analysis for fictitious play of two-person, two-strategy games. Some generalizations are also given.

Two producers delegate sales of differentiated products to common retailers, each with a monopoly position. Each producer can offer either a linear or a two-part tariff. In the single period game each producer's dominant strategy is to use a two-part tariff. If the two producers' products are...
