银行危机与货币危机共生性关系的实证研究

1 997— 1 998年的亚洲金融风暴中 ,银行危机与货币危机的同时爆发 ,即共生性危机的发生引发国际社会与学术界对这种现象的重新思考 :这种共生性现象是否确实具有普遍性 ?从理论的角度来看 ,银行危机与货币危机之间的确存在着一定的联系 ,但到目前为止 ,很少有研究从实证的角度来证明这种联系的确存在。正是基于此 ,本文从实证的角度出发 ,旨在揭示出银行危机与货币危机之间的确存在着相互影响 ,换言之 ,共生性危机的发生是具有显著性的。具体来说 ,本文以 1 975— 2 0 0 0年期间 53个国家危机的发生情况为研究对象 ,分别运用频率分布、信号法 ,以及概率回归模型来分析两种危机的共生性 ,并得到非常一致的结论 :在新兴市场国家中 ,银行危机与货币危机之间的确存在着明显的相互关系 ,同时银行危机更趋向于作为货币危机即将发生的同步或预警指标 ,而反之则不然。     

农户生物菌肥购买意愿及行为的影响因素研究*——基于山东省设施菜农的调研数据

[目的]生物菌肥对于土壤改良、环境改善、食品安全具有重要意义,但目前生物菌肥在整个肥料产业中所占份额较小,迫切需要探讨如何从农户角度提高生物菌肥的施用比例。[方法]基于设施蔬菜农户的数据,构建Bivariate Probit模型,对农户生物菌肥的购买意愿和行为的影响因素进行比较研究。[结果]农户的生物菌肥购买意愿和行为总体上呈现一致性,愿意购买的农户中有97. 77%的农户具有实际的购买行为;但两者的影响因素有所差异,从差异因素来看,质量安全检测对购买意愿具有显著的正向影响,但对购买行为的影响并不显著;农户文化程度、种植年限、对无公害、绿色、有机蔬菜的了解程度,经销商推荐,施肥指导对购买行为具有显著的正向影响。从共同因素来看,生态环境认知变量对购买意愿和购买行为影响不显著。[结论]要推广生物菌肥,需要进一步加强质量安全检测体系对农业行为的约束性,提升经销商的规范经营意识,采用集中招标等灵活的价格政策,提升农户的生态技能,并在保护生态环境方面出台更完善的农业绿色发展政策。     

The demand for organic foods in the South of Italy: A discrete choice model

This paper analyses organic food consumer’s demand that can help advising on implementing organic food policies at European level or, for a particular European country. In particular, it investigates the main factors explaining organic food demand in the South of Italy. Following the Lancaster consumer’s demand theory we assume that consumer’s utility depends on product characteristics instead of the product itself. Thus, consumers will choose the product (organic versus conventional) that possesses the combination of attributes that maximises its utility. Consumer’s choice for organic foods is analysed within the random utility discrete choice model and a bivariate probit model has been specified. The data were collected through a questionnaire conducted in the Italian region of Campania (Naples) in 2003. Findings indicate that economic factors are still factors limiting the growth of organic demand in Europe. Moreover, the consumers’ perceived benefits of organic food (environmental and health) are factors promoting organic food demand. In addition, greater information on organic food products is crucial to expand its demand in the South of Italy because this information will increase the consumer’s organic knowledge. Then, higher organic knowledge will increase the probability to buy organic foods and, to a larger extent, the level of consumption among existing consumers.     

我国老年人心理孤独感及其影响因素研究

随着我国老龄化社会的到来和空巢家庭的逐渐增多,老年人的心理健康,特别是心理孤独感问题已引起社会越来越多的关注。基于实证调查数据,结合Probit回归模型分析老年人孤独感的影响因素,对当前我国老年人的心理孤独现状进行研究,发现老年人的年龄、身体健康状况、户籍、家庭关系、经济收入状况等都会对其孤独心理产生影响,并进而分年龄、分户籍对研究结论进行稳健性检验。在总结研究结论的基础上,从社会、家庭和个人三个层面对我国老年人心理健康事业的发展提出若干思考。     

西部地区农户金融需求及其影响因素的实证分析

以中国西部地区农户的借贷为基本研究对象,结合有关调查数据,分析了农户的信贷需求情况,并用Probit模型分析了西部地区农户金融需求的影响因素。分析表明：西部地区农户具有广泛的金融需求但从正规金融机构获得贷款的比例较低,其对利息具有一定的承受能力,借贷以短期、小额为主,用途兼有生活与生产性、但以生活性为主,借款未归还的比重较低。人口、劳动力、学生人数、劳动力平均年龄、劳动力最高受教育程度、家庭经营的土地面积、家庭收入、家庭储蓄水平、家庭收入来源、家庭距正规金融机构的距离、信用社是否对农户的评级、农户所在地是否存在有息借贷等指标,是影响西部地区样本农户是否具有金融需求的显著因素。     

山区农户对森林旅游业的参与意愿及影响因素研究

在行为经济学相关理论的基础上,基于福建山区221个农户的调研数据,运用有序Probit模型探究影响农户参与森林旅游业意愿的主要因素。研究结果表明:山区农户对森林旅游业的参与意愿不高;性别、健康状况、家庭成员是否为党员或干部、屋前是否通公路、家庭成员累计出外打工时间、对森林旅游政策了解程度、政府扶持力度及未来收益预期等因素是影响农户对森林旅游业参与意愿的主要因素。基于此,建议提高农村妇女参与森林旅游业的综合能力、加强政策的支持与引导及推进森林旅游业产业链延伸等。     

政治关联与公司治理有效性——基于上市公司证券违规的数据

管理者政治关联在强化企业竞争优势的同时,也会弱化公司治理机制的有效性.本文基于公司违规行为发生及管理者被迫离职两个方面,利用Bivariate Probit模型和Logit模型研究管理者政治关联对公司治理有效性的影响.研究发现,拥有政治关联的管理者所在企业更加倾向发生违规行为,尤其是民营企业;管理者的政治关联能够降低其违规行为被稽查处理的可能性,尤其是国有企业.政治关联有助于管理者建立职位壕沟,降低管理者被迫离职的概率;而企业违规行为被稽查后,管理者被迫离职的可能性将显著提高.文章的研究结果证明,管理者政治关联会弱化企业发生违规行为的事前监管,同时也会降低企业违规行为的稽查在事后监管中的公司治理效果.     

Analysis of household attitudes toward the purchase of livestock products and fish in Cameroon

The need for additional information on household demand for meat and fish in Cameroon is addressed. Probit analysis involving the Heckman selectivity correction procedure is used to estimate the effects of individual and household characteristics on demand for beef, chicken, pork and fish. Results indicate that fish is a relative necessity in Cameroon and is often substituted for beef and chicken by households whose profiles include being of low income levels, having large household sizes, are of middle age and are less educated. Whereas chicken and pork substitute each other, they are each complementary to beef. The profiles of households likely to purchase beef include being married, middle age, educated and of the Muslim faith. Profiles for households most likely to increase their purchases of chicken include being of high income levels and are public sector employed. Some policy implications are provided.     

Are ‘New’ Donors Different? Comparing the Allocation of Bilateral Aid Between nonDAC and DAC Donor Countries

Major DAC donors are widely criticized for weak targeting of aid, selfish aid motives, and insufficient coordination. The emergence of an increasing number of new donors may further complicate the coordination of international aid efforts. At the same time, it is open to question whether new donors (many of which were aid recipients until recently) are more altruistic and provide better targeted aid according to need and merit. Project-level data on aid by new donors, as collected by the AidData initiative, allow for empirical analyses comparing the allocation behavior of new versus old donors. We employ Probit and Tobit models and test for significant differences in the distribution of aid by new and old donors across recipient countries. We find that, on average, new donors care less for recipient need than old donors. New and old donors behave similarly in several respects, however. They disregard merit by not taking the level of corruption in recipient countries into account. Concerns that commercial self-interest distorts the allocation of aid seem to be overblown for both groups.
