There are two types of micro-states, islands and mainland ones. Except for a few islands very close to the coast, most of the insular micro-states are demographically very different from the rest of the Third World. Their death-rates are lower, their birth-rates lower, and the propensity of their populations to migrate to developed countries higher. It is argued here that these differences are based on other social and economic differences, which can be summarized by saying that such states are more Westernized. They were part of the European maritime system at a time when the West did not have the economic strength to penetrate continental areas to the same extent. On the whole they retained colonial links longer. 相似文献

The implications of supermodularity conditions in comparative-static analysis are analyzed for a generalized version of the
separable-effort representation of a firm facing stochastic prices and a stochastic technology. Previous analysis is generalized
in two ways. General risk-averse, as opposed to expected-utility, preferences are considered. The stochastic technology is
represented by an Arrow–Debreu state-space representation. It is shown that results familiar from the theory of the price-taking
firm in the absence of risk generalize to the uncertain case.

An implicit rental price approach is used to analyse the determinants of farm tractor investment at the aggregate level. Three models, based on different assumed factor substitutabilities, are compared. Variations in the rental price of tractors appear to have less effect on demand than variations in factors affecting the profitability of the cropping enterprise as a whole. The implications for forecasting and for policy instruments, such as the investment allowance, are discussed. 相似文献

Costs of adjustment to climate change 总被引:1,自引:0,他引:1

The present paper argues that the costs of climate change are primarily adjustment costs. The central result is that climate change will reduce welfare whenever it occurs more rapidly than the rate at which capital stocks (interpreted broadly to include natural resource stocks) would naturally adjust through market processes. The costs of climate change can be large even when lands are close to their climatic optimum, or evenly distributed both above and below that optimum. 相似文献

It has often been suggested that more stable wool prices would lead to an outward shift in the long-run demand for wool. To assess this claim it is necessary to examine different sources of risk and instability in wool prices and their impact on the risk borne by wool users. A model is presented in which the input and output decisions of a wool processor are related to interactions between the wool and yarn markets. It is concluded that, if fluctuations in final demand or exchange rates are the major sources of instability, the long-run effect of stabilising prices is to increase the risk faced by wool users and reduce that faced by wool growers. 相似文献

Risk has long been recognised as an important feature of the environment facing farmers. In recent years the von Neumann-Morgenstern expected utility theory has been used to analyse decision making under risk. However, many people behave in a manner inconsistent with the expected utility theory. One widely suggested explanation is based on subjective probability distortion. A number of attempts to incorporate this phenomenon into utility theories have been made. In this paper, the problems of analysing subjective probability distortion are discussed. Evidence from a survey of farmers' risk attitudes undertaken in conjunction with the 1977 BAE Australian Agricultural and Grazing Industries Survey is analysed in the light of this discussion. 相似文献

(Magill, M., Quinzii, M., 2002. Capital market equilibrium with moral hazard. Journal of Mathematical Economics 38, 149–190) showed that, in a stockmarket economy with private information, the moral hazard problem may be resolved provided that a spanning overlap condition is satisfed. This result depends on the assumption that the technology is given by a stochastic production function with a single scalar input. The object of the present paper is to extend the analysis of Magill and Quinzii to the case of multiple inputs. We show that their main result extends to this general case if and only if, for each firm, the number of linearly independent combinations of securities having payoffs correlated with, but not dependent on, the firms output is equal to the number of degrees of freedom in the firm’s production technology. 相似文献

The fundamental assumption of the contingent valuation method (CYM) is that responses to CY questionnaires may be interpreted as expressions of consumer preferences. The consumer preference interpretation has been challenged in recent papers arguing that willingness to pay for wildlife preservation is generated, at least in part, by ethical concerns, rather than by a view that wildlife preservation will yield any benefit to individual respondents. Some further evidence bearing upon these questions is derived from a study of forest management in Australia undertaken by the Resource Assessment Commission (RAC). The evidence supports the interpretation that respondents are acting primarily as citizens. 相似文献
