Forests produce benefits over and above the revenue yielded from timber and other wood based products. Most important among these may be the recreational benefits for visitors, which have been examined in several studies. Total benefits for residents are perhaps more accurately captured in property values since, ceteris paribus, the price of a house reflects willingness to pay to live near an environmental amenity such as a forest to gain access to it, and also the amenity (non-use) value of the forest in so far as it creates a pleasant landscape. However, the total non-priced value of forestry is not the sum of HPM and ITCM benefit estimates. Recreational benefits will typically be less, and will be subsumed in the HPM estimates, since the hedonic price is partly induced by the value of recreational access.  相似文献

This paper utilizes the average derivative estimation of Stoker (1986) and the pesudo-likelihood estimation of Fan, Li, and Weersink (1996) to estimate a semiparametric stochastic frontier regression, y = g(x) + , where the function g(.)is unknown and is a composite error in a standard setting. The proposed semiparametric method of estimation is applied to data on farmers' credit unions in Taiwan. Empirical results show that the banking services of the farmers' credit unions is subject to economies of scale, but high degree of cost inefficiency in operation.  相似文献

Historically, major consideration given to product management has focused on research and development or the introductory stage of the product life cycle. The authors present an empirical study delineating the variables to be considered in the product elimination process. More specifically, the elimination process is evaluated under a situation of poor product performance despite a generally viable market. The basic objectives of the study were: to determine the significant variables in the product elimination process of the Small Appliance Industry; to determine the relative importance of the variables; to examine the interaction among variables. The data obtained through personal structured questionnaire interviews were analyzed and provided a ranking of twenty-six variables relevant to the elimination process. Moreover, the Johnson's Hierarchical Clustering Schemes was applied to determine the interaction among variables. The results indicate that profitability and financial variables are most significant in the elimination decision-process. Second, the primary clusters of importance are concerned with market share, market growth rate, consumer awareness, and competitive action.  相似文献

The purpose of this paper is to show how modern techniques of Temporary competitive equilibrium analysis can be applied to models of the “pure consumption loan model” type. One considers Samuelson's simplest model where traders live two periods and where money is the only store of value. It is proved that a temporary equilibrium exists if price expectations are sufficiently independent of current prices. A stationary market equilibrium is shown to exist if there is a set of traders (i) whose total resources are greater when they are young than when they are old, (ii) who are indifferent between present and future consumption. It is proved that this existence theorem still holds if the economy is sufficiently “close” to an economy which has this property. A stationary market equilibrium is shown to be Pareto optimal if all traders hold positive cash balances. It may be inefficient if this condition is not satisfied, for some traders may then be willing to borrow, which they cannot do in this model.  相似文献

A stochastic frontier production function is used to estimate the effect of partial and gradual reforms in the 1980’s in each of seven state-owned manufacturing industries. Reform-induced gains in technical efficiency were significant in all sample industries although not always substantial enough to motivate industry-wide productivity growth. The bonus system had speedy and impressive efficiency effects, but there is no consistent evidence on the effectiveness of other reform measures, including greater output autonomy, partial exposure to market influences, and the possibility of dismissals for malfeasance. Equalization of marginal factor returns across firms was observed in some industries, which may be considered as evidence of improved allocative efficiency in response to the reforms.  相似文献

In many developing countries, the potential benefits from adopting a transgenic variety developed by a multinational corporation are limited by the crop’s small production base. This paper presents an ex-ante evaluation of the economic impact of herbicide resistant transgenic rice in a small developing country, Uruguay. To fully account for the multinational’s market power, the firm’s seed markup is assumed to affect the adoption rate for the variety. Stochastic simulation techniques are employed to understand how potential benefits may vary with changes in technology, yield, costs, and adoption parameters. The results indicate a $1.82 million mean net present value for producers from the development and utilization of transgenic rice in Uruguay and $0.55 million for the multinational. These relatively small multinational firm benefits suggest that a firm will not undertake significant efforts to develop transgenic varieties adapted to local conditions without either strategic partnerships with local institutions or access to wider regional markets.  相似文献

These three books take different approaches to analysing the transformative potential of the Landless Workers Movement (MST) in Brazil. Vergara‐Camus' book also examines the Zapatista National Liberation Army (EZLN). Carter solicited essays from numerous specialists and sees his book as contributing to existing efforts to overcome inequality. Mészáros emphasizes the influence of power relations on the law, determining that it takes an organized pressure group such as the MST to ensure that authorities implement policies that challenge the status quo. Vergara‐Camus' grassroots approach, which involved periods of living with peasant families, concludes that the MST's strategies for building alternative, autonomous rural communities is more realistic – more universalistic – than that of the Zapatistas, whose military tactics tend to reinforce the group's isolation in the forests of Mexico's southernmost state. The review evaluates these arguments, the authors and their evidence from the perspective of a researcher experienced with the objects studied.  相似文献
