A number of problems in agricultural economics involve modeling joint distributions for which the assumption of multivariate normality may not be warranted. Yet, very little work has been conducted evaluating competing methods for modeling joint dependence. We develop a simulation framework to evaluate the bias and efficiency impacts of copula choice in the context of evaluating county‐to‐farm basis risk. The results suggest significant differences in performance across various copulas and approaches. The findings have important implications for risk analysis, insurance, and policy modeling problems in agriculture regarding the selection of method to model dependence among random variables.  相似文献

Asiatic citrus canker is a disease that poses a significant hazard to commercial citrus production. This article examines spatiotemporal models of the risks of citrus canker transmission. Models evaluate risks and are used to price annual contracts, which would pay producers a prespecified indemnity in the event that their grove is found to be infected with canker. Implications for risk management policy are discussed.  相似文献

In this paper, we have examined the impact of both bank- and market-based financial development on economic growth in Kenya during the period 1980 to 2012, using the autoregressive distributed lag bounds testing approach. To capture as far as possible the breadth and depth of the Kenyan bank- and market-based financial systems, the study employs the method of means-removed average to construct both bank- and market-based financial development indices from an array of banking sector and stock market variables. The empirical results of this study show that market-based financial development has a positive impact on economic growth in Kenya. However, the results have also shown that bank-based financial development has no impact on economic growth in the study country. These results apply irrespective of whether the regression analysis is conducted in the long run or in the short run. The findings of this study, therefore, lend more support to pro-market-based financial development policies in Kenya.  相似文献

ABSTRACT

This study investigates job location and its relationship with employee turnover intention within the casino-entertainment industry. The researchers analyzed turnover intention at the supervisor and company level from the perspective of employees who hold front-of-house or back-of-house jobs in three Nevada casinos and their corporate office. The results of this research fill existing gaps in the academic literature related to turnover intention and provide beneficial implications for industry and academic practitioners. Organizations within the casino-entertainment industry may develop strategies related to the management of human capital that could provide fiscal and operational benefits.  相似文献

Wildlife tourism experiences have the potential to positively impact tourists’ awareness, appreciation and actions in relation to the specific wildlife they encounter and the environment in general. This paper investigates the extent of such impact across multiple sites, and uses Structural Equation Modelling to identify factors that best predict positive long-term learning and environmental behaviour change outcomes. Three sets of variables were measured – visitors’ entering attributes (including pre-visit environmental orientation and motivation for the visit), salient aspects of the experience, and short- and long-term learning and environmental behaviour change outcomes. Although attributes such as pre-visit commitment and motivation to learn were among the best predictors of the long-term impact of the experience, there was evidence that aspects of the experience were also important. In particular, reflective engagement which involved cognitive and affective processing of the experience was found to be associated with short- and long-term environmental learning outcomes. The implications for wildlife tourism managers are discussed.  相似文献

The U.S. Department of Transportation (DOT) defines a flight as “delayed” if it arrives 15+ minutes late. The DOT “flight counting” delay definition is used to rank airline/airport service quality. An obvious caveat of counting flight delays is that the duration of delay plays no role in the delay count. The purpose of this article is to propose an aggregate delay measure that is sensitive to the distribution of time delayed among passengers. The importance of this work is that our derived delay measure reflects passenger preferences rather than the arbitrary delay cutoff established by the DOT. We model passengers' preference ordering using the criteria that passengers prefer fewer, shorter, and more equal delay times.  相似文献

This study evaluates the implications of an existing carbon tax on international trade in the agricultural sector. Applying uniformly to all fossil fuels combusted within its borders, the province of British Columbia unilaterally introduced a carbon tax on July 1, 2008. In 2012, the province granted an exemption from the tax to certain agricultural sectors. Using commodity‐specific trade flows and exploiting cross‐provincial and intertemporal variation, we find little evidence that the carbon tax is associated with any meaningful effects on agricultural trade despite the sector being singled out as “at risk” by the provincial government. Our findings suggest that there is not compelling evidence to support exempting the agricultural sector from the tax. Discussion of potential policy remedies to address the tax's potential effects on firm profitability and international competitiveness is also included.  相似文献

We use line integral theory to lay out in a more general theoretical framework the conditions under which it is possible to measure with market data the welfare effects of a change in a nonmarket good. We present in detail a numerical method of measuring the value of nonmarket goods using market data, under either weak neutrality or weak complementarity. Our numerical method is more flexible than the existing analytical method because it can be used with any well-behaved Marshallian demand function, and can be used even when the willig condition does not hold.  相似文献

We develop a unified sequence of models to examine the determinants of price, output, profitability and concentration for different kinds of oligopolistic market. We relate various magnitudes of significance to judges of welfare and to policy makers, such as consumer surplus, profit, or added benefits of employment or trade surplus, to observable magnitudes such as the size and concentration of the market. It emerges that various appropriately formulated Herfindahl indices are useful in several of these relations. We attempt to present results in a way that is useful for empirical investigations and pay particular attention to applications in trade and development.  相似文献
