Burning bluegrass seed stubble is an important production practice that, among other benefits, increases production and stand life of this perennial crop. Despite economic forecasts that higher production costs from the 1996 state ban on seed stubble burning would reduce Washington production by up to 30%, output in the years 1998–2005 was nearly two-thirds higher than in any previous eight-year period. This study seeks to explain why that paradoxical behavior occurred. This study puts forward and systematically tests several hypotheses. The only hypothesis with any support, innovation offsets, is examined by an assessment of contemporaneous innovations and by corroborative statistical evidence.  相似文献

Retail decentralization is associated with town centre decline and a concern for revitalization. Using the case of Llanelli, South Wales, the effects of a new food superstore on shopping behaviours and opinions are explored. Surveys in 1997, 1999 and 2001 reveal a dramatic change in patterns of food shopping, but no real change for purchases of clothing or DIY goods. Disadvantaged consumers, the carless and the elderly, were already heavily reliant on town centre shops before the opening of the new superstore and changes in their shopping patterns were no different from other shoppers. The 'social' vitality of the town centre increased, as did shoppers' satisfaction with town centre shopping, but major spin-off shopping or 'economic' vitality has not yet occurred.  相似文献

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.  相似文献

This paper analyzes the problem of designing mechanisms to implement efficient solutions in economies with externalities. We provide two simple mechanisms implementing the Pigouvian Social Choice Correspondence in environments in which coalitions can or cannot be formed.  相似文献
