This paper analyzes the marketing system of potato in Bangladesh, especially the economic relations among farmers, traders, and cold storage owners and elucidates the structural changes in the rural economy through a village study. Investment in the potato market is capital‐intensive and risky, and is often considered to be vertically linked. The present study shows that farmers and cold storage owners do not invest in trading because of lack of time and “skill” to deal with urban traders. Besides, farmers face capital constraints and the amount of potatoes produced is too small to meet the demand of urban areas. Cold storage owners are confronted with increasing competition, which forces them to attempt to reach the storage capacity. Traders invest in the risky potato‐storage business. The return from it is declining but still high due to the “cheap” credit supply from the cold storage owners. There is no tied relation among the market agents any more.  相似文献

Structural adjustment policies have been adopted in the ASEAN-4 countries. The policy changes were intended to shift manufacturing from import substitution to export promotion. We assess how successful this was using the Asian International Input-Output Tables for 1975 and 1985. The success of structural adjustment is verified, as the number of export-led industrial sectors increased in each of the ASEAN-4 countries. The 1-0 tables are used to evaluate the similarity of industrial technologies and input structures of the ASEAN-4, Japan, and other Pacific Rim economies. While there are some similarities in industrial technologies with Japan, input structures are dissimilar. Interdependence increased between the ASEAN-4, Japan and the United States. Increases in US final demand had a larger impact on ASEAN-4 textile exports, however, than did increases in Japanese final demand.  相似文献
