In public policy planning and budgeting, the health issues and homeless issues tend to be interrelated and reinforced by each other, but this mutual causality is usually ignored in the existing literature. This paper provides an unbiased estimate of a structural equation model taking endogeneity into account. A questionnaire is designed based on the health-related quality of life (EQ-5D) framework and is given to 322 homeless individuals. Evidence shows that, without timely support, the homeless state and health state will fast deteriorate and reinforce each other. It is therefore arguable to broaden the definition of statutory homelessness, and the “preventative approach” can save, rather than increase, the public resources spent on the homeless. 相似文献

The relationship between wage difference and relative employment is a very important issue in the field of economic structural change. An M-sector economic growth model is constructed in this paper to investigate the relationship between wage difference, price difference, technology gap, relative employment and sectoral dynamic change from the perspective of technologies. Labor flow is regarded as a decision-making behavior to maximize the benefits of economic agents. The benefits of labor flow mainly come from sectoral wage difference, and the costs of labor flow mainly come from the social resource expenditure during labor flow process. Our model illustrates that: (i) the relative employment is positively correlated with the real wage difference and technology gap; (ii) the sectoral dynamic changes coexist with the aggregate economic growth; (iii) increases in technology gap, and price and wage differences will stimulate labor migration, exacerbate the unbalanced growth of sectoral economies, and lead to faster and more effective aggregate economic growth. 相似文献

We present a novel approach for modelling self serving bias by way of reference dependence. Bias is modelled as a systematic individual level deviation of the endogenous reference point from the expected price of a good in a two person k-double auction. We find that bias decreases the efficiency of the model, and that efficiency is decreasing in both the level of bias and reference dependence. 相似文献

High‐speed rail (HSR) has led to a transportation revolution in China. This paper uses the county‐level panel data of China’s Yangtze River Delta to investigate the effect of HSR connection on local economy. To address the issue of endogenous HSR route placement, we use a straight‐line strategy to construct potential HSR connection variables as instrumental variables of the actual HSR connection. Both the difference‐in‐differences and instrumental variable methods show that HSR connection impedes local economy, especially in peripheral regions. The impediment effect is channeled through population reallocation from peripheral to core areas and the restructuring of industries. 相似文献

基于2001~2017年中国工业分企业所有制-分地区-分行业的面板数据,利用相对劳动生产率和变异系数指标对全国和分区域的国有企业、私营企业、外商和港澳台企业的劳动生产率增长和收敛性进行描述性分析,并运用双向固定效应模型对其进行计量检验。结果显示:从全国范围来看,三类所有制结构的劳动生产率均呈现显著的绝对收敛和条件收敛,但是收敛速度呈现差异。其中,私营企业收敛速度最快,外商和港澳台企业次之,国有企业收敛速度最慢。分区域来看,东北和西部收敛速度相对较快,中部次之,而沿海三类所有制结构的劳动生产率收敛速度均较慢。因此,政府应进一步从深化国有企业改革、鼓励非公有制经济发展和完善市场竞争等方面努力,有助于缩小区域发展差距和促进所有制结构的收敛,从而带动整体经济的收敛。 相似文献

We use an empirical gravity equation to study how non-reciprocal trade preferences (NRTPs), enacted mainly through the Generalized System of Preferences, affect the exports of the beneficiary nations. In line with existing studies, the average trade effect stemming from non-reciprocal preferences is highly unstable across specifications. However, once we allow for heterogeneous effects, results become robust and economically important. Specifically, NRTPs have a strong effect on the exports of beneficiaries when they are members of the World Trade Organization and are very poor. Not-so-poor beneficiaries also expand foreign sales, but only if they are not WTO members. For all others, the average export effects of NRTPs are mute. 相似文献

Numerous studies in the marketing literature focused on consumer behavior in general, but relatively few studies have examined Impulse purchase behavior (IPB). Although few studies examined IPB, the vast majority of the studies were conducted using the cross-sectional design. These studies suffer from certain limitations like random measurement error, common method bias, causality & validity-related issues that are inherently associated with the cross-sectional design. Despite these limitations, very few studies have examined the IPB using the longitudinal design. Multilevel structural equation modeling (ML-SEM) is conducted in the study to analyze the longitudinal data for examining the changes in the causal effects of the factors influencing the shoppers' IPB over a period of time. Additionally, structural equation modeling (SEM) is conducted to examine changes in the causal effects of the factors influencing IPB at each time point of data collection. Drawing upon the stern's model and stimulus-organism-response model, the study examines the causal effects of the factors influencing the IPB. The results of ML-SEM indicate significant fluctuations in the factors influencing IPB over time. Similarly, the results of SEM indicates that few factors (like store ambience and salesperson interactions) have shown a significant influence on IPB in the initial time points (i.e., during the initial store visits of shoppers), but became insignificant over a period of time in their subsequent store visits. The findings suggest that the store crowd, secondary customers influence, and in-store promotions show a significant influence on the IPB, compared to the store ambience and salesperson interactions. 相似文献

基于2008—2017年国家林业局对中国28个省(市、区)国有林场的调研数据,运用等价性检验的方法从地理位置、经济状况、可持续经营和发展能力层面上对国有林场的贫困测度和差异性进行实证分析。研究结果表明:国有贫困林场不一定位于贫困县,并且与国有非贫困林场之间的差异逐渐缩小;国有贫困林场区域异质性强,经济发展水平较低;国有贫困林场在森林资源基础、人力资源基础、基础设施和生产条件等方面的可持续发展能力较差。因此,提出了相关林业部门应该鼓励国有贫困林场发展特色林产品;加大扶贫资金投入;改善职工生计条件;加强资金管理意识等政策建议。 相似文献

[目的]随着我国人民生活水平的提高,绿色农产品愈发得到消费者的青睐。文章旨在探析消费者绿色农产品意愿溢价水平及其溢价支付意愿的驱动路径,以期为绿色农产品产业的发展提供相应政策启示。[方法]基于MOA理论分析框架,利用结构方程模型和消费者调查数据,该文以主粮大米为例展开分析。[结果]以普通大米5元/kg为基准价格,消费者绿色大米平均意愿溢价水平为125.7%,意愿溢价水平从高到低排序依次是东部地区(145.2%)、中部地区(140.09%)、西部地区(91.82%)。[结论](1)利己动机、利他动机、创新性能力、信息获取能力能够直接作用于消费者绿色农产品溢价支付意愿,而消费机会通过利己动机、利他动机和信息获取能力间接作用于溢价支付意愿;(2)基于多群组结构方程,研究发现个人可支配收入和文化程度能够调节消费者创新性能力、信息获取能力对消费者绿色农产品溢价支付意愿影响;(3)消费者创新性能力和信息获取能力对溢价支付意愿的影响存在地域差异性。 相似文献
