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

The announcement of a convertible bond call is associated with an average contemporaneous abnormal stock price decline of 1.75% and an ensuing price recovery in the conversion period. A price fall and the subsequent recovery suggest price pressure as the explanation for the announcement effect. However, in general the option to convert is not exercised early and hence, the increase in the number of shares outstanding does not occur at the announcement date. Instead, this paper argues and provides evidence that hedging-induced short selling causes at least part of the short-run price pressure. 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

This article examines how trade union membership varies across 16 OECD countries in the 1980s. Higher density of membership is found to be associated with a higher degree of centralisation of wage bargaining, higher percentage of employees covered by collective bargaining, a larger public sector and a more leftist party of government. 相似文献

Using the Hamilton-Jacobi-Bellman equation, we derive both a Keynes-Ramsey rule and a closed form solution for an optimal consumption-investment problem with labor income. The utility function is unbounded and uncertainty stems from a Poisson process. Our results can be derived because of the proofs presented in the accompanying paper by Sennewald (2006). Additional examples are given which highlight the correct use of the Hamilton-Jacobi-Bellman equation and the change-of-variables formula (sometimes referred to as ``Itô's Lemma'') under Poisson uncertainty. 相似文献

abstract This paper calls for research on organizational improvisation to go beyond the currently dominant jazz metaphor in theory development. We recognize the important contribution that jazz improvisation has made and will no doubt continue to make in understanding the nature and complexity of organizational improvisation. This article therefore presents some key lessons from the jazz metaphor and then proceeds to identify the possible dangers of building scientific inquiry upon a single metaphor. We then present three alternative models – Indian music, music therapy and role theory. We explore their nature and seek to identify ways in which the insights they generate complement those from jazz. This leads us to a better understanding of the challenges of building a theory of organizational improvisation. 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
