Estimation of a cost function for a representative sample of UK dairy producers allows future re‐structuring of the industry to be simulated using a model which incorporates producers' differential costs and milk prices. Consideration is also given to reductions in producer prices and to the introduction of an A/B quota system. The results indicate that, despite the history of quota trading in the UK, there is considerable scope for further restructuring in the industry to take advantage of differential incentives between producers. It is also projected that UK milk supply would increase if quota restrictions were removed.  相似文献

Duration Analysis of Technological Adoption in Ethiopian Agriculture   总被引:1,自引:0,他引:1  
Duration analysis has been used to examine the impact of time‐varying and time‐invariant variables on the speed of adoption of fertiliser and herbicide by smallholder farmers in East and West Shewa in the central highlands of Ethiopia in the 25 years preceding 1996. The estimated models suggest that economic incentives were the most important determinants of the time farmers waited before adopting new technologies; traction power in the form of oxen and infrastructural factors (in particular proximity to markets) also appear to have been important influences, but less so than prices. Other agricultural inputs (area of farmland, labour, credit), extension services and farmers' personal characteristics (education, gender, age) appear to have had little, if any, effect on adoption behaviour. There is also evidence that the speed of adoption of herbicide, on both tef and wheat, was slower than that of fertiliser.  相似文献

The paper investigates whether the changing pattern of meat and fish purchases, which has occurred in Britain since the 1960s, is due to changes in the structure of consumer preferences or is attributable to conventional economic factors (changes in relative prices and total expenditure). The analysis is based on two non-parametric tests, derived from revealed preference theory. These do not require the explicit specification and estimation of a demand system. The hypothesis that the data are consistent with stable preferences is accepted; in principle, all variations in consumption can be fully explained by price and expenditure changes. However, some caution is counselled. As with all hypothesis testing, acceptance is less conclusive than rejection; some structural changes in preferences may have gone undetected.  相似文献

This paper uses a disaggregated approach to study the volatility of common stocks at the market, industry, and firm levels. Over the period from 1962 to 1997 there has been a noticeable increase in firm-level volatility relative to market volatility. Accordingly, correlations among individual stocks and the explanatory power of the market model for a typical stock have declined, whereas the number of stocks needed to achieve a given level of diversification has increased. All the volatility measures move together countercyclically and help to predict GDP growth. Market volatility tends to lead the other volatility series. Factors that may be responsible for these findings are suggested.  相似文献

This study examines the predictions of group polarization in response to the receipt of qualitative information (i.e., good or bad news) in a laboratory market. Qualitative information induces varying beliefs within the market because such information is interpreted using the relevant knowledge possessed by the recipients. Findings from the group polarization literature suggest that individuals who subsequently hold the most extreme price beliefs will influence the market to a greater extent than individuals holding the most conservative beliefs. Group polarization research also suggests that participation in a market will accentuate risk preferences so that good news produces a cautious shift in prices (i.e., towards lower prices) whereas bad news produces a risky shift (i.e., towards higher prices). The results confirm the predictions of group polarization and further suggest that if extreme reactions to information reflect recency, so too may the market price.  相似文献

This paper examines the determinants of external credit ratings attained by insurance firms in the United Kingdom (UK) and of the likelihood that insurers will have such an assessment. Using panel data relating to A.M. Best‐rated and Standard and Poor's (S&P)‐rated insurers over the period 1993–1997, a trichotomous logit model and an ordered probit model with sample selection are employed to show that the factors which influence the likelihood of having external credit assessments not only vary between the two agencies but also differ from those which determine the ratings themselves. Our results are shown to be of potential interest to participants in the insurance industry and policy‐makers alike.  相似文献

While qualitative surveys regarding consumers' attitudes about gene technologies and their application to food production are plentiful, quantitative studies are less so. The present paper reports choice modelling methods to examine the conditions under which Australian consumers are willing to purchase genetically modified (GM) foods, if at all, and examines those preferences within the context of the food system as a whole. This allows us to compare consumer attitudes towards gene technology to consumer preferences for other features of the food they consume. The results of the choice modelling analysis suggest consumers require a discount on their weekly food bill before they will purchase GM food. Gene technology using animal as well as plant genes was found to be more objectionable to respondents than that using plant genes alone, especially among women. Age seems to affect the preferences for a certain type of food, with older people generally more accepting of the use of gene technology.  相似文献
