This article documents the popularity of five types of trail-based recreation relative to other forms of recreation that tourists frequently participate in on their trips; identifies these trail users’ cross-participation in other outdoor recreation activities; and profiles the travel behaviour, media habits, trip planning behaviour, and demographic and socioeconomic characteristics of day hikers and snowmobilers as two particularly large trail user segments. Findings are based on data from a household telephone survey conducted in Michigan, surrounding states, and Ontario, Canada. Hiking/backpacking was found to be the most popular natural resource-based recreation activity that respondents participated in on pleasure trips taken during the past 12 months; other forms of trail-based recreation were significantly less popular; mountain bikers participated in nature-oriented recreation activities in Michigan at levels that were similar to those of hikers/backpackers; and snowmobiling appeared to be the focus of most pleasure trips on which this activity occurred, in contrast to day hiking, which appeared to be more of an ancillary pursuit. 相似文献

Abstract: Prior to the 1980s, Ghana witnessed an alternating cycle of boom and scarcity, culminating in the introduction of structural adjustment policies in the early 1980s. This paper uses data from the Ghana Forestry Services, Ministry of Food and Agriculture, FAO Yearbook of Forestry Products, Ghana Timber Marketing Board, Quarterly Digest of the Ghana Statistical Service, World Debt Tables, Bank of Ghana, IMF, COCOBOD and Ministry of Finance to examine the impact of SAP on deforestation in Ghana. The paper reveals a negative impact of structural adjustment on deforestation in Ghana through both direct and indirect channels. The most important channel of the effect of SAP on deforestation resulted from the conversion of forestland to crop farming, particularly cocoa farming, during the post‐adjustment period. Even though wood extraction exhibited a negative impact on deforestation, the impact seemed relatively weaker than that of agricultural land use. In addition, while in the long run, deforestation tended to be more responsive to logging than agriculture, in the short run the elasticity of deforestation with respect to agriculture tended to be greater than that with respect to logging. Finally, agriculture was relatively more important in causing deforestation. 相似文献

Search and Liquidity in Single-Family Housing 总被引:5,自引:0,他引:5
A two-stage least squares model of housing prices is estimated with data collected from 3358 single-family home transactions. The results provide evidence for an optimal marketing period and indicate that a liquidity premium is priced in single-family home sales. Consistent with the hypothesis derived from economic search models, the model shows higher selling prices for houses having longer expected marketing periods. The model also shows a price premium for houses that sell faster than expectations. This effect supports the concept that liquidity is a value-enhancing characteristic. 相似文献

Using a panel of 45 states for the period 1982–1997,this study analyzes the importance of severalrestrictive alcohol regulations, including advertising bans for billboards, bans of price advertising, state monopoly control of retail stores, and changes in the minimum legal drinking age. In contrast to previous research, the study allows for substitution among beverages as a response to a regulation that targets a specific beverage. A restrictive law that applies only to one beverage (or one form of advertising) can result in substitution toward other beverages (or non-banned media). Allowing for substitution means that the net effect on total alcohol consumption is uncertain, and must be determined empirically. The empirical results demonstrate that monopoly control of spirits reduces consumption of that beverage, and increases consumption of wine. The effect on beer is positive, but is not statistically significant. The net effect on total alcohol is significantly negative. Higher minimum legal drinking age laws have negative effects on beverage and total alcohol consumption. Bans of advertising do not reduce total alcohol consumption, which partly reflects substitution effects. The study thus demonstrates the possible unintended consequences of restrictive alcohol regulations. 相似文献

This research examines whether suppliers’ capabilities impact OEM customers’ dependence on the supplier and thereby generate
customer loyalty. Using a sample of purchasing managers focusing on a single key component supplier, we examine three supplier
capabilities, two dependence dimensions, and three aspects of customer loyalty. Core offering capability increases the customer
firm’s benefit-based dependence. Operations capability has a more comprehensive effect, enhancing both benefit-based and cost-based
dependence. Benefit-based dependence leads to relational loyalty and, through its effect on relational loyalty, to insensitivity
to competitive offerings and future purchase expansion. Cost-based dependence motivates insensitivity to competitive offerings,
but does not affect relational loyalty or purchase expansion. The supplier’s communication capability is associated with relational
loyalty, but this effect does not flow through the customer firm’s dependence. The divergent pattern of antecedents and effects
of benefit-based dependence and cost-based dependence may explain the inconsistent and insignificant research findings in
previous research on dependence. Our results suggest that adopting a bi-dimensional model of dependence more fully captures
the theoretical domain of dependence, thereby permitting researchers to better examine its role in supply chain, channel,
and marketing relationships. 相似文献

Monetary policy for an open economy: an alternative framework with optimizing agents and sticky prices 总被引:5,自引:0,他引:5
The 'new open-economy macroeconomics' seeks to provide an improvedbias for monetary and exchange-rate policy through the constructionof open-economy models that feature rational expectations, optimizingagents, and slowly adjusting prices of goods. This paper promotesan alternative approach for constructing such models by treatingimports not as finished consumer goods but rather as raw-materialinputs to the home economy's productive process. This treatmentleads to a clean and simple theoretical structure that has someempirical attractions as well. A particular small-economy modelis calibrated and its properties exhibited, primarily by meansof impulse response functions. The preferred variant is shownto feature a pattern of correlations between exchange-rate changesand inflation that is more realistic than provided by a morestandard specification. Important recent events are interpretedin light of the alternative models. 相似文献

A binomial approximation to a diffusion is defined as 'computationallysimple' if the number of nodes grows at most linearly in thenumber of time intervals. It is shown how to construct computationallysimple binomial processes that converge weakly to commonly employeddiffusions in financial models. The convergence of the sequenceof bond and European option prices from these processes to thecorresponding values in the diffusion limit is also demonstrated.Numerical examples from the constant elasticity of variancestock price and the Cox, Ingersoll, and Ross (1985) discountbond price are provided. 相似文献
