The aim of the paper is to investigate certain aspects of the post‐adoption behaviour of dryland cotton farmers in the Ubombo and Hlabisa magisterial districts of KwaZulu. Particular attention is paid to the socio‐economic determinants of the success (returns per hectare) of the household cotton enterprise.
Multi‐stage sampling methods were used to draw a random sample of fifty cotton‐farming households from each of the two study districts. The data were collected by interview survey and analysed using principal components and regression techniques.
Results suggest that the success of the household enterprise in both areas is largely determined by the socio‐economic environment under which the producer operates. The most important success‐determining factors are those relating to the human capital endowments and economic status of the household. 相似文献

Resource based relative value scale: a new challenge and opportunity for health care cost management
Beginning in 1992, the use of resource based relative value scale (RBRVS) will greatly change the way physicians are reimbursed for services to Medicare patients. This new system will also have implications for trust funds and corporate providers of health care benefits. 相似文献

Manfen W. Chen Rohan Christie-David William T. Moore 《Journal of Regulatory Economics》2007,31(3):289-312
We hypothesize that the firm’s regulatory environment influences the sensitivity of its equity value to information. Using
intraday stock price data of utilities operating in differing regulatory environments we test for systematic differences between
the responsiveness of stock prices of utility firms operating in deregulated and regulated environments to a common information
set. Our findings reveal sharp differences in responses, with those of utilities operating in deregulated environments the
strongest, and the responses of utilities in highly regulated environments the weakest. While the evidence supports our hypothesis,
in a broader sense, the evidence suggests that deregulation aids in the process of price discovery. We also find evidence
that suggests that deregulation, per se, does not lead to higher stock price volatility.

THE ROLE OF EXCHANGE RATE IN SINO-U.S. BILATERAL TRADE 总被引:3,自引:0,他引:3
We use the error component two-stage least squares estimation method to examine the effects of the Sino-U.S. exchange rate and the weighted exchange rate between the United States and other Asian countries on the Sino-U.S. trade patterns. Our study suggests that both the exchange rates have contributed to China's increased trade surplus with the United States. China has imported intermediate goods from the Asian countries, produced final goods using its cheap labor, and exported those goods to the United States. This is especially true for bilateral trade of high-tech manufacturing goods. Our study also reveals that the U.S. bilateral trade balance could improve if China appreciates its currency (Yuan) against the U.S. dollar. ( JEL F14, F10, F19) 相似文献

This paper gives an overview of the bioeconomic modelling of marine reserves, and illustrates how economists have responded to the modelling results found in the ecological literature. The economic analysis is shown to be far more pessimistic with regards to the potential of marine reserves as a fisheries management tool, than what one finds in the purely ecological analysis, the reason being the latter's neglect of issues such as discounting and economic incentive behaviour. However, economic analysis, despite some of it being relatively advanced with regards to spatiality, is still simplistic with regards to for instance ecosystem and habitat content. A simple expansion of the existing bioeconomic models with regards to positive habitat effects of area closures is presented and analysed, showing room for improved results from marine reserve implementation as compared to the existing analysis. 相似文献

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the
quantitative implications of a simple two-sector general equilibrium model that gives rise to multiplicity, and calibrate
the model for 127 countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be
in a low output equilibrium. We also find that, since the output gains associated with an equilibrium switch are sizeable,
the model can explain between 15 and 25% of the variation in the logarithm of GDP per worker across countries. 相似文献

The Productivity of US States since 1880 总被引:1,自引:0,他引:1
This study uses state-level variation in labor productivity levels at twenty-year intervals between 1880 and 1980 to examine the relative importance of institutional and geographical influences in explaining observed and persistent differences in standards of living over time and across regions. Focusing on fundamental rather than proximate influences, we find that both institutional characteristics and some physical geography characteristics account for a high proportion of the differences in state productivity levels: states with navigable waterways, a large minerals endowment, and no slaves in 1860, on average, had higher labor productivity levels throughout the sample period. However, we find little support for two other influences that have previously received attention—climate and latitude. 相似文献
