“三位一体”农民工健康服务体系及其保障机制研究

分割型城乡二元劳动力市场与弱健康人力资本的交互累积效应、健康服务支出的沉没成本效应、伦理价值观的惯性约束效应、农民工主体的弱健康服务诉求及信息传递障碍的制约,使我国农民工健康服务供给明显不足,难以形成一个完善的农民工健康服务体系。因此应当构建一个以政府为中心、企业广泛参与的农民工健康服务体系的"三位一体"模式,并设立以企业为核心的制度保障机制,发挥政府的主导性作用。

The hierarchy of roads, the locality of traffic, and governance

This study investigates the use of road networks both within and outside of home jurisdictions (city (or town) and county of residence) by analyzing GPS data collected in the Minneapolis—Saint Paul metropolitan area. The study tracked volunteers' travel behavior to determine which roads (and thus which class of roads) users chose to accommodate their travel needs. More than half of the travel on county roads and city streets occur outside of one's home city, but most travel is within one's home county. The average share of travel distance in the home county is more than 70% for both county and city streets. The high share, which does not account for non-residents destined for the county to work or shop, e.g., implies that the free rider problem on city and county streets at the county level is minimal. Of particular concern is travel on city roads in cities other than one's own. To the extent that this is to go to a destination in that city, that travel is also local. However, because city and county roads are typically funded by those jurisdictions from land-based sources such as property taxes, through trips with neither end in the city through which they are traveling are in a very real sense “free riders”, and pose a problem. With growing trip lengths and emerging economies of scale in road management, it may be appropriate to consider moving more roads from township, town, or city level to the county level of government.     

A supply chain network design considering transportation cost discounts

This study addresses an integrated facility location and inventory allocation problem considering transportation cost discounts. Specifically, this article considers two types of transportation discounts simultaneously: quantity discounts for inbound transportation cost and distance discounts for outbound transportation cost. This study uses an approximation procedure to simplify DC distance calculation details, and develops an algorithm to solve the aforementioned supply chain management (SCM) problems using nonlinear optimization techniques. Numerical studies illustrate the solution procedures and the effects of the model parameters on the SCM decisions and total costs. Results of this study serve as a reference for business managers and administrators.     

Human Resource Management Practices and Trust in Public Organizations

Abstract

Trust has been acknowledged as a valuable managerial resource within organizations. Working as a lubricant of organizational functioning, trust reduces opportunistic behaviours while it increases voluntary compliance to organizational norms and rules as well as enhancing individual and organizational performance. Considering the importance of trust, it is worthwhile to explore what factors may help build trust within organizations. This research investigates whether perceptions of several human resource management (HRM) practices are associated with trust in government organizations. According to social exchange theory, HRM practices signal management's commitment to employees which in turn leads to greater trust in the organization. Using data from an employee survey conducted for the Georgia Department of Transportation in 2007, this research tests how employee perceptions of HRM practices are related to trust in three distinct levels of management in a large department of state government: trust in department leadership, trust in one's leadership team, and trust in one's supervisor. Binary logit analyses suggest that perceptions of HRM practices focusing on autonomy, compensation, communication, performance appraisal, and career development are associated with trust in public organizations. According to the result, those practices present variation in their leverage on trust in leadership at different levels.     

农产品出口信贷担保国家分配的影响因素研究——以美国为例

文章在介绍农产品出口信贷担保背景的基础上,选取1999-2007年15个使用美国农产品短期出口信贷担保的国家为研究对象,分析美国制定这种政策措施的影响因素。研究发现:这种政策措施的设计初衷是为了维持和扩大现有国际市场的份额,并开拓竞争出口国不占有优势的市场;而且,措施的实施并不是用于救济那些无钱从国际市场购买粮食的国家。     

城市最低生活保障兼有消费改善与劳动供给激励效应吗?

最低生活保障制度是我国社会保障体系中兜底性、基础性的制度安排,是保障民生、促进分配公平、维护经济安全和社会稳定的重要机制.本文通过对城市低保制度消费改善与劳动供给效应的综合评估发现,我国城市低保从整体上改善了受助家庭的消费状况,影响了受助家庭的消费结构,起到了提升经济福利的效果,但是对受助家庭的劳动供给激励效应还比较小...     

安全活动对物流企业绩效作用的实证分析

本文以物流企业为调查对象进行问卷调查,通过Bootstrapping和结构方程模型的路径分析,分析了物流安全活动对成本控制,运输效率和企业绩效之间的影响关系.同时,以路径分析结果为基础,提出了推广物流安全实践活动和提高物流企业绩效的意义.结果表明,安全运输实践及安全运输预防管理对成本控制和运输效率都有着显著的积极影响,运输手段安全管理对成本控制有着显著的积极影响,而运输手段安全管理对运输效率产生的影响力在5％的显著性水平下不显著,成本控制对运输效率也产生了显著的积极影响关系,成本控制和运输效率对企业绩效也都有着显著的积极影响.

General equilibrium trade modelling with Canada–US transportation costs

Transportation costs are an important topic in international trade, but seldom have researchers paid attention to general equilibrium trade modelling with transportation costs and explored their relevant effects. This paper uses numerical general equilibrium trade model structures to simulate the impacts of transportation costs on welfare and trade for a Canada–US country pair case. We compare two groups of model structures: Armington assumption models and homogeneous goods models. Within these two groups of models, we also compare balanced trade structures to trade imbalance structures and production function transportation costs to iceberg transportation costs. Armington goods models generate more absolute welfare gains from transportation cost elimination than homogeneous goods models. Welfare gains under balanced trade structures are larger in production function transportation cost scenarios than in iceberg transportation cost scenarios, but under trade imbalance structures, welfare gains are greater under iceberg transportation cost scenarios. Canada's welfare gains in the iceberg transportation cost scenario are significantly larger than gains in the production function transportation cost scenario. On trade effects, homogeneous goods models generate more export and import gains, balanced trade structures have more trade variations, and iceberg transportation costs generate more trade effects.
