Genetically modified cotton varieties have greater production efficiency for smallholders in farming communities in China. We also find that the adoption of Bacillus thuringiensis (Bt) cotton varieties leads to a significant decrease in the use of pesticides. Hence, we demonstrate that Bt cotton appears to be an agricultural technology that improves both production efficiency and the environment. In terms of policies, our findings suggest that the government should investigate whether or not they should make additional investments to spread Bt to other cotton regions and to other crops. 相似文献

We examined nine marketing textbooks, published since 1927, to see if they contained useful marketing principles. Four doctoral students found 566 normative statements about pricing, product, place, or promotion in these texts. None of these statements were supported by empirical evidence. Four raters agreed on only twenty of these 566 statements as providing meaningful principles. Twenty marketing professors rated whether the twenty meaningful principles were correct, supported by empirical evidence, useful, or surprising. None met all the criteria. Nine were judged to be nearly as correct when their wording was reversed.The authors thank the many people who commented on early drafts, including Eileen Bridges, Fred Collopy, Douglas Dalrymple, Alan Dubinsky, Andrew Ehrenberg, Jonathan Freeman, Raymond Hubbard, William Perreault, William Ross, Steven Schnaars, and Gerald Zaltman.

This paper estimates that credit scoring is associated with about a $3,900 increase in small business lending per sample banking organization, per low‐ and moderate‐income (LMI) area served, and this effect is roughly equivalent to that estimated for higher‐income areas. For our sample, this corresponds to a $536 million increase in small business credit in LMI areas in 1997 than otherwise would have been the case. This effect appears to be driven by increased out‐of‐market lending by banking organizations, as in‐market lending generally declines. Overall, it does not appear that credit scoring has a disparate impact on LMI areas. 相似文献

When does social support alleviate or exacerbate the effects of being excluded by colleagues in the workplace? This study integrates belongingness and social support theories to predict and demonstrate the differential effects of work‐related support (i.e., perceived organizational support; POS) and non‐work‐related support (i.e., family and social support; FSS) on employee reactions to co‐worker exclusion. Consistent with our predictions, we found that employees reporting high levels of co‐worker exclusion and high levels of perceived organizational support demonstrate higher levels of performance and increased levels of self‐worth than those reporting low levels of POS. Alternatively, support from family or friends intensified the negative relationship between co‐worker exclusion and self‐esteem and the positive relationship between co‐worker exclusion and job‐induced tension. Unexpectedly, FSS did not influence the supervisor‐rated task performance of excluded workers, nor did POS mitigate the relationship between co‐worker exclusion and job‐induced tension. Implications for theory, research, and practice are discussed. 相似文献

The construction of multi-regional input–output tables is complex, and databases produced using different approaches lead to different analytical outcomes. We outline a decomposition methodology for investigating the variations that exist when using different multiregional input–output (MRIO) systems to calculate a region's consumption-based account. Structural decomposition analysis attributes the change in emissions to a set of dependent determinants, such as technical coefficients, the Leontief inverse and final demands. We apply our methodology to three MRIO databases – Eora, GTAP and WIOD. Findings reveal that the variation between Eora and GTAP can be attributed to differences in the Leontief inverse and emissions’ data, whereas the variation between Eora and WIOD is due to differences in final demand and the Leontief inverse. For the majority of regions, GTAP and WIOD produce similar results. The approach in this study could help move MRIO databases from the academic arena to a useful policy instrument. 相似文献

This paper addresses the impacts of liquidity constraints on household postharvest commodity selling behavior. Using data collected from China's maize farmers, we find that households with debt, in general, sell their maize much earlier than debt‐free households, thus potentially losing inter‐temporal arbitrage opportunities. Segmenting our sample into wealthy and poor households, we find that the relationship between a liquidity constraint and postharvest sales is apparent only among poor households. Using the occurrence of an illness in children or an elderly household member as an instrument for liquidity, we control for potential endogeneity associated with liquidity. We find that poor households in which there were children or elderly people with sicknesses in previous years are more likely to sell maize early than other poor households. 相似文献

This study provides an assessment of methods used in existing tourism research to measure emotion and discusses the potential for use of psychophysiological methods such as electro-dermal analysis, facial muscle activity, heart rate response, eye-tracking system and vascular measures. Psychophysiological measurement techniques have been reported in the marketing, advertising and media literature; however, to the best knowledge of the authors, no studies are reported in the tourism literature. Instead, studies of emotion in the tourism literature invariably employ self-report questionnaire methods which capture only tourists' high-order emotions and are subject to a variety of forms of bias. Unconscious emotional responses that can provide unbiased portrayal of individuals' initial emotional reactions when exposed to a stimulus have been largely ignored. The paper concludes that studies combining both self-report and psychophysiological measures are needed and areas for future research are discussed. 相似文献

Despite increasing institutional and financial support, certain public health issues are still neglected by the Chinese Government. The present paper examines the soil-transmitted helminth (STH) infection and reinfection rates by conducting a survey on 1724 children in Guizhou Province, China. Our results indicate that 37.5 percent of children had been infected with one or more of the three types of tested STH. However, only 50.4 percent of children reported having taken deworming medicine during the 18-month period before the survey. Of those who reported being dewormed, 34.6 percent tested positive for STH infections. Poverty and number of siblings are significantly and positively correlated with infection and reinfection, and parental education is significantly and negatively correlated with infection and reinfection. Given the ineffectiveness of treatment in these areas to date, for anthelminthic campaigns to actually succeed, China must pay more attention to local- level incentives to improve children's health. 相似文献

This study examines laboratory market outcomes under alternative matching risk scenarios and advance production. Limited access and/or asymmetry in the number of buyers and sellers cause a matching problem. When sellers hold inventory before sale and there is buyer concentration, prices are about 23% below the competitive level and close to the predicted monopsony price. The bargaining advantage shifts to buyers in this market environment. Sellers can benefit by creating alliances or cooperatives to increase their bargaining position for price and overcome poor access to buyers. 相似文献
