Salinity and drainage management options include source control, reuse, and evaporation ponds. This article identifies efficient strategies to maintain hydrologic balance in closed drainage basins and evaluates their impact on regional agricultural profits. Theoretical analysis suggests that economic efficiency requires acknowledgment of the nonseparability between water use and land value. Empirically, our solution involves a modest amount of source control, a substantial amount of reuse, and the elimination of evaporation ponds often associated with large environmental damages, while maintaining grower income. Various policy instruments and options are introduced and discussed, including a system of drainwater charges, marketable permits, and land retirement. 相似文献

This paper discusses emotions as mediators in business-to-business relationships which is an understudied topic. Yet within consumer marketing, emotions have been widely studied, and calls have been made for business relationship research to take account of managers' emotions. This study addresses the gap by firstly establishing the relevance of emotions in problematic business relationships and secondly showing how emotions are a major component in determining the outcomes of the problematic relationships. Interview data in the form of narratives describing problematic relationships is analyzed and identifies both the emotions experienced by participants and their role in the future course of the business relationship. 相似文献

This paper uses a logit model to test whether voters will alter their support for incumbents in state level elections, specifically gubernatorial and state house and senate elections, when local (i.e., county) economic conditions are observed. The results signify that voters do hold the incumbent party responsible for economic conditions. Furthermore, voters tend to place more emphasis on unemployment levels than on real personal income indicating that incumbent politicians might want to engage in policies that put people to work rather than on policies that raise income. The results also suggest that voters did not hold their state house and senate representative as responsible for local economic conditions as they did the governor. 相似文献

We investigate whether productivity differences explain why some manufacturers sell only to the domestic market while others serve foreign markets through exports and/or FDI. When overseas production offers no cost advantages, our model predicts that investors should be more productive than exporters. An extension allowing for low-cost foreign production can reverse this prediction. Data for 1070 large Japanese firms reveal that firms that invest abroad and export are more productive than firms that just export. Among overseas investors, more productive firms span a wider range of host-country income levels. J. Japanese Int. Economies 17 (4) (2003) 448–467. 相似文献

A bstract . Economists have long studied the determinants and effects of income transfers. This article examines an indirect effect of welfare payments on participating individuals: an increase in the incidence of sexually transmitted disease ( STD ) rates.
Several studies have found a significant and positive link between the size of welfare benefits and out-of-wedlock fertility rates. Higher welfare payments reduce the cost of bearing and raising a child, and thus reduce the full cost of engaging in unprotected sex. An unintended consequence of unprotected sex is exposure to contagious diseases. This implies that states with higher welfare payments per child will experience higher rates of STDs.
We test this hypothesis using statewide data on the incidence of three types of bacterial STDs, chlamydia, gonorrhea, and syphilis, for the years 1994 through 1998. The empirical specification is based on the standard microeconomic model of utility-maximizing behavior. The included explanatory variables are demographic proxies reflecting differences in state population characteristics. These characteristics capture unobservable or intrinsically unmeasureable differences in the perceived costs and benefits of engaging in unprotected sex.
The explanatory variable of primary interest is the size of the real welfare payment per recipient. Our empirical results indicate that states with higher real welfare payments are associated with greater rates of STDs. 相似文献

Value-at-Risk Prediction: A Comparison of Alternative Strategies 总被引:4,自引:0,他引:4

Given the growing need for managing financial risk, risk predictionplays an increasing role in banking and finance. In this studywe compare the out-of-sample performance of existing methodsand some new models for predicting value-at-risk (VaR) in aunivariate context. Using more than 30 years of the daily returndata on the NASDAQ Composite Index, we find that most approachesperform inadequately, although several models are acceptableunder current regulatory assessment rules for model adequacy.A hybrid method, combining a heavy-tailed generalized autoregressiveconditionally heteroskedastic (GARCH) filter with an extremevalue theory-based approach, performs best overall, closelyfollowed by a variant on a filtered historical simulation, anda new model based on heteroskedastic mixture distributions.Conditional autoregressive VaR (CAViaR) models perform inadequately,though an extension to a particular CAViaR model is shown tooutperform the others. 相似文献
