离散选择模型的基本原理及其发展演进评介 总被引:10,自引:0,他引:10
离散选择模型的研究真正兴起于19世纪50年代末,属于微观计量经济学的范畴。该模型能够对个体和家庭行为进行经验性的统计分析,因而在经济学和其他社会科学中得到广泛的应用。本文从离散选择模型的基本性质及效用最大化的理论背景出发,指出logit模型虽然使用的是最早并且最为广泛的离散选择模型,但是其存在着三大局限性:不能表示随机口味的变化、暗含成比例的替代形式和不能处理不可观测因素在不同期间相关的情形。GEV(含嵌套logit)、probit和混合logit模型等其他的离散选择模型,很大程度上都是为了避免这些限制而产生并发展起来的。 相似文献

集聚效应对跨国公司在华区位选择的影响 总被引:17,自引:0,他引:17
本文以跨国公司区位选择微观理论为基础,利用条件Logit模型,对2007年《财富》世界500强中,1995年到2007年期间,457家美国子公司和537家欧洲子公司在华个体区位选择决定因素进行了实证分析。分析结果表明,集聚效应是样本公司区位选择的重要决定因素,在华投资的欧美制造业公司普遍采用"集聚"这一战略,其子公司大量集聚在东部地区,盲目吸收外资来缩小东—西部经济发展不平衡的政策并不合适,尤其是中部地区。因此,在文章末,本文对中国政府应该如何减小区域经济发展不平衡和合理引用外资提出了建议。 相似文献

We analyze the motives and determinants of voluntarily stock exchange section switching on the NYSE Euronext. By strategically deciding trading-section transfer when it is beneficial, managers expect to reduce their liquidity and invisibility costs, cost of capital, or their listing costs. We show that managers decide to change the trading compartment of their common stocks based on various factors including firm's size, liquidity level, debt ratio, and expected growth opportunities. Firms that move voluntarily from a less or non regulated compartments to a more regulated one are likely to have transferred to increase their credibility, improve their stocks’ liquidity, re-balance their leverage, and to finance their growth opportunities. Whereas those that move their common stocks toward a less-regulated compartments do it mainly for costs saving reasons. 相似文献

基于中国劳动力动态调查(CLDS)数据,运用广义有序Logit模型实证分析户籍、家庭禀赋和城市特征三类因素对城市家庭住房不平等的影响;运用夏普利值分解、Oaxaca-Blinder分解区分"努力"和"环境"因素、户籍歧视和禀赋效应的贡献。研究发现:户籍可解释住房等级不平等的54.2%;"努力"因素对住房水平起正向作用;在户籍间住房等级不平等中户籍歧视效应占主导,在住房面积不平等中禀赋效应占主导,外地户口居民住房水平低源于"环境"因素趋弱,农业户口居民则源于"努力"和"环境"因素叠加趋弱;由于生活成本效应占主导,城市规模和流动人口占比越大,居民住房等级趋低,而城市土地供给增长有助于提升住房水平。 相似文献

The lack of effective farmer demand is a major factor that restricts the development of China's forest insurance. To solve this problem, this study uses a Logit model to conduct an empirical analysis of relevant factors in the farmers’ demand for forest insurance, based on field survey data of Lin’an County, Zhejiang Province. The results show that the farmers’ understanding of forest insurance, the proportion of forestry revenues in the total household income, forest size, forest disaster frequency, forest insurance liability, insurance amount setup, and the farmers’ satisfaction regarding the premium subsidy policy, are the main factors that affect the farmers’ demand for forest insurance. Therefore, we propose to expand forest insurance promotion, raise the farmers’ income, rationally design insurance products, and optimize the forest premium subsidy policy to enhance the farmers’ willingness to participate in forest insurance. 相似文献

We study the effect of introducing a bilingual option on the long run equilibrium outcome in a class of two-strategy coordination games with distinct payoff and risk dominant equilibria under the logit choice rule. Existing results show that in the class of two-strategy games under consideration, the inefficient risk dominant equilibrium is selected in the long run under noisy best response models. We show that if the cost of the bilingual option is sufficiently low then the efficient payoff dominant equilibrium will be selected in the long run under the logit choice rule. 相似文献

The risk of being involved in an airplane accident is largely ignored in air passengers’ choice models. The reason presumably is that it is hard to operationalize, because objective safety indicators often involve extremely low probabilities that are hard to grasp and interpret by passengers. In this paper, we propose an operationalization that is based on the perception of safety, which is easy to understand and resonates that perceptions often influence decisions stronger than objective variables. We conceptualize that passengers form a safety perception score of a particular flight based on their perception of airline and route attributes and that this score in turn is traded-off against other flight attributes, such as ticket costs, to arrive at a flight choice. In line with this conceptualization, two stated preference experiments are conducted. In a first experiment, combinations of airline and route attributes are evaluated in terms of safety that is captured on a rating scale. In a second experiment, safety perception is treated as an attribute and traded-off against other flight attributes to arrive at a flight choice. The paper presents the results of a regression and a Panel Mixed Logit model estimated from responses obtained from a convenience sample of 161 air passengers recruited in the Netherlands. The results of both models are then combined to calculate the willingness to pay values for improvements made to a range of airline and route attributes, taking into account socio-demographic variables and psychological traits. As expected, the results indicate that the willingness to pay for improving safety decreases with higher initial safety levels. 相似文献
