While presidents try to allocate resources to their interests in budgeting process, they have limited power to influence because the government budget is approved by the legislative body. This study investigates whether presidents asymmetrically use information on the efficiency of programs to allocate more resources to their interests. Specifically, I focus on leftover funds in the government reporting. Growing leftover funds indicate inefficiency of the programs as they are the results of lack of demand or operational problems in implementation. Using data from the Korean government, I find that the change of leftover funds of programs and the following year’s budget has a negative relation only when the change of leftover funds is negative, which suggests that the efficiency of the program improves. This phenomenon becomes more salient when the programs are related to the president’s political interests. This suggests that presidents allocate resources to the programs of their interests by asymmetrically using the information on efficiency. This study contributes to the extant literature by identifying one of the presidents’ tools to affect the budgeting process.  相似文献

Drawing on social identity theory, we hypothesize that professionals develop their organizational and work-unit identifications through organizational prestige and work-unit prestige respectively. We further hypothesize that professional status negatively interacts with organizational prestige and work-unit prestige to affect the development of their organizational and work-unit identifications from the perspectives of self-enhancement and uncertainty reduction. A two-phase survey on 386 hospital nurses in central China provides general support for the hypotheses. Implications for theory and practice are discussed.  相似文献

We review the empirical valuation literature on pesticide riskexposure and develop a taxonomy of environmental and human healthrisks associated with pesticide usage. Meta-analysis is thenused to investigate the variation in willingness to pay (WTP)estimates for reduced pesticide risk exposure. Our findingsshow that the WTP for reduced risk exposure is 15 per cent greaterfor medium, and 80 per cent greater for high risk levels, ascompared with low risk levels. The income elasticity of reducedpesticide risk exposure is generally not significantly differentfrom zero. Stated preference approaches based on choice experimentsand revealed preference provide lower WTP estimates than contingentvaluation techniques. Survey design, type of safety device (eco-labelling,integrated pest management, or bans) and chosen payment vehicleare important drivers of the valuation results.  相似文献

Les données financières de 92 entreprises agricoles conventionnelles produisant un minimum de 20 hectares de céréales à paille et de 21 entreprises, biologiques ou en phase de transition avancée, cultivant au moins 15 hectares de céréales ont été extraites de la banque de données Agritel pour fins de comparaison. À partir des entreprises conventionnelles, quatre groupes sont formes: bas niveau d'intrants (BNI), haut niveau d'intrants (HNI), rendement faible (extensif) et rendement eleve (intensif).
Pour l'ensemble des céréales, ainsi que pour l'orge, les entreprises biologiques obtiennent des rendements et des charges significativement plus faibles par rapport á l'ensemble des entreprises conventionnelles. Ainsi, les marges brutes sont équivalentes. La dépendence des entreprises biologiques et conventionnelles vis-à-vis des aides gouvemementales contribue toutefois pour une part importante aux résultats obtenus. La rentabilité des entreprises biologiques est comparable à celle des entreprises conventionnelles au niveau global de l'entreprise.
Par rapport aux quatre sous-groupes formés, le groupe biologique se situe, pour les marges brutes sur les cultures entre les groupes les plus performants (groupes BNI et intensif) et les moins rentables (groupes HNI et extensif).
Des logiques de production totalement différentes peuvent done aboutir à des résultats économiques similaires, du moins á court terme.  相似文献

This study explores linkages between what Chinese managers generally know about environmental issues, how strongly they value environmental protection, and different types of behaviours/actions they may take within their organizations on behalf of the environment. From a sample of 305 managers in Guangzhou and Beijing, it was found that both environmental knowledge and values are more predictive of more personal managerial behaviours, such as keeping informed of relevant company issues and working within the system to minimize environmental impacts, than more overt behaviours. Moreover, for these more personal actions, environmental knowledge and values were found to have both main and interactive effects. By comparison, it was found that both environmental values and knowledge had additive effects on managerial tendencies to initiate new programs within their domain of responsibility. Only environmental values was found to have a modest influence environmental advocacy.  相似文献

This paper examines the link between relative goods prices and relative wages during two periods of Mexico's trade liberalization. The relative price of skill-intensive goods rose following Mexico's entrance to the General Agreement and Tariffs and Trade (GATT) in 1986, but fell after Mexico entered the North American Free Trade Agreement (NAFTA) in 1994. This paper adds a band pass filter to two established techniques to compare the relationship between prices and wages. Results from all three approaches are consistent with a positive long-run relationship between relative output prices and relative wages. The band pass filter results suggest that the relevant time frame for the relationship begins after 3-5 years.  相似文献

We analyze the effect of Toyota's faulty accelerator pedal on stockholder wealth. Using the event study methodology, we show that a major recall in January of 2010 is associated with a 19% fall in the company's cumulative abnormal returns. Continued concerns that Toyota was unable to identify and adequately fix the problem prompted the National Highway Traffic Safety Administration to conduct its own investigation in March, 2010. The results of this government investigation exonerated the company and Toyota's cumulative abnormal returns rose by almost 9%. The Toyota case provides an opportunity to study a product recall with both company error and a government action that addressed concerns about the safety of the product.  相似文献

来源国效应相关理论在国际市场营销和国际化战略领域占据重要地位,国外相关研究由来已久,研究内容也已形成理论族群,但该领域的研究仍然存在相关概念的模糊和理论框架的缺失;针对来源国效应的检验由于样本差异、控制变量差异等因素的存在,相关结论尚无法形成体系化理论支撑。尤其是针对发展中国家逆向拓展发达国家市场时的来源国效应研究相对匮乏,一些调节变量的影响机理仍有待揭示。国内学者最近几年才开始关注来源国效应,主要聚焦于不同属性产品的来源国效应检验。文章回顾了来源国效应的相关概念演变,梳理了来源国效应的三种理论基础,总结了发展中国家企业进入发达国家的品牌战略,整合了研究内容的理论框架,概括了该领域常用的研究方法,并在此基础上指明了未来研究方向。文章作为一篇理论综述,希望通过文献梳理和分析,厘清研究主干和研究分支,为后续研究提供基础和参考,克服“只见树木、不见森林”的弊端。  相似文献
