Transaktionen und Institutionen: Zur Effizienz von Märkten, Unternehmen und Verbänden am Amazonas

The investigation focuses on different types of vertical integration of small-scale enterprises which wholesale fish in the peruvian Amazon Basin: independent merchants, backward integration from merchants into fish production and backward, lateral and forward integration into associations of fishermen and merchants. A comparative institutional analysis is developed, institutional theories are compared with empirical findings and a test of hypotheses is carried out.
The organizational, socioeconomic and historical questions which are advanced are: Which organizational forms and institutions can be empirically found? How did these modes of economic organizations evolve historically? Which of the firms comprise the most efficient exchange relationships and how the differences in efficiency can be explained? What do the variables and hypotheses of Oliver E. Williamsons transaction cost economics and Douglass C. Norths institutional theory render?
