The objectives of this paper are to incorporate a measure of risk aversion in the translog frontier cost function to estimate cost inefficiency. Risk-averse behaviour of farmers is hypothesised to reduce efficiency by leading to a situation in which the marginal value product of an input is less than price. In developing agriculture, farmers are aware of their subsistence needs and seek to minimize the probability of their incomes falling below a disaster level of income. Using such a safety first principle, a measure of risk-taking is developed and explained by socio-economic characteristics. This measure is used in the translog cost function as a fixed input and, using the frontier approach (with half normal distribution of inefficiency disturbance), a measure of cost inefficiency is obtained. This is related to socio-economic characteristics such as education, assets and holding size. A survey data of 436 farmers for the North-West Frontier Province of Pakistan is used to reach policy conclusions for reducing cost inefficiency.  相似文献

This study measures the variability in real net farm income in the U.S. agricultural sector and per farm and determines if variability has diminished over 1933 to 1999. Second, the role of nonfarm income in reducing the variability in total farm household income is examined. Results indicate that the variability in real net farm income in the sector and at the farm level has not diminished and that nonfarm income has helped to reduce the variability in total farm household income.  相似文献

Using China Family Panel Studies (CFPS), this study investigates factors associated with the choice of farmland leasing strategies and the impact of leasing options on farm performance. Particular attention is given to off‐farm employment and farm subsidies. Additionally, the study applies a selectivity‐based approach to assess the relationship between farmland leasing choices and farm businesses’ performance. Off‐farm employment, older and educated operators, large farms and old‐age pension plans increase the likelihood of leasing out farmland. Part‐time off‐farm employment, grain subsidies and mechanised farms increase the likelihood of leasing in farmland. Finally, the selectivity correction terms in the value of crop production are significantly negative in the choices of farmland leasing, indicating the presence of sample selection effects. Accounting for selectivity is essential to ensure unbiased and consistent estimates.  相似文献

This paper investigates the German car scrappage program, focusing on the incidence of the premium. We ask how much of the €2500 ($3500) buyer subsidy is actually captured by the demand side. More precisely, we analyze the program’s impact on different car segments, allowing for heterogeneity in incidence at different points in the vehicle price distribution. Using a unique microtransaction data set, we find that the incidence of the subsidy strongly and significantly varies across price segments. Subsidized buyers of cheap cars paid a little more than comparable buyers who did not receive the subsidy, indicating incidence amounts slightly below 100 %. For more expensive vehicles, subsidized buyers were granted large extra discounts on top of the government premium, translating into incidence amounts considerably greater than 100 %. Taken together, this results in an aggregate incidence amount of up to plus €350 million, suggesting that the positive effect for expensive cars overcompensates the negative effect for small cars.  相似文献

The precautionary principle (PP) aims to anticipate and minimize potentially serious or irreversible risks under conditions of scientific uncertainty. Thus it preserves the potential for future developments. It has been incorporated into many international treaties and pieces of national legislation for environmental protection and sustainable development. In this article, we outline an interpretation of the PP as a framework of orientation for a sustainable information society. Since the risks induced by future information and communication technologies (ICT) are social risks for the most part, we propose to extend the PP from mainly environmental to social subjects of protection. From an ethical point of view, the PP and sustainability share the principle of intergenerational justice, which can be used as an argument to preserve free space for the decisions of future generations. Applied to technical innovation and to ICT issues in particular, the extended PP can serve as a framework of orientation to avoid socio-economically irreversible developments. We conclude that the PP is a useful approach for: (i) policy makers to reconcile information society and sustainability policies and (ii) ICT companies to formulate sustainability strategies.  相似文献

The determinants of off-farm work by married farm couples are examined using data from the 2004 Agricultural Resource Management Survey and multinomial logistic regression. Expected government payment is found important in decreasing the likelihood of off-farm work strategies involving work by the husband only or by both husband and wife relative to a strategy of no work by either husband or wife. The marginal impact of government payments on the probability of the wife working off farm alone is found positive suggesting the possibility of nonpecuniary motives for off-farm employment for 21% of farm households in the selected weighted sample.  相似文献

Summary  B est [1] found the variance of the minimum variance unbiased estimator of the parameter p of the negative binomial distribution. M ikulski and Sm [2] gave an upper bound to it, easier to calculate than B est's expression and a good approximation for small values of p and large values of r (the number of successes). In this paper both lower bounds and closer upper bounds are derived.  相似文献

This article reviews the trends in government subsidies and investments in and for Indian agriculture; develops a conceptual framework and a model to assess the impact of various subsidies and investments on agricultural growth and poverty reduction; and presents reform options with regard to re‐prioritizing government spending. Subsidies in credit, fertilizer, and irrigation have been crucial for small farmers to adopt new technologies particularly during the initial stage of the green revolution in the late 1960s and 1970s. But it is now investments in agricultural research, education, and rural roads that are the three most effective public spending items in promoting agricultural growth and reducing poverty.  相似文献
