区域经济协调发展中的不平衡增长

推进区域经济协调发展是我国经济发展战略中的重要内容之一,但协调发展并不意味着平均主义,由于每个城市在区域内分工网络中所充当的角色不同,不平衡增长是必然的。     

“霍山现象”中的民营企业研究

作为国家级贫困县的霍山县,其工业经济在短短的十几年间奇迹般地崛起,被经济学界称之为“霍山现象”、“霍山模式”。霍山民营企业对“霍山现象”的形成起关键性作用。本文通过对霍山民营企业的调查研究,分析了促进霍山民营企业成长的几个重要因素,并剖析了民营企业在投资环境、治理结构及融资等方面存在的问题,提出了进一步发展民营企业的对策建议。

The Poverty of Politics: How Income Redistribution Hurts the Poor

In spite of the significant research literature identifying a tradeoff between income redistribution and economic growth, massive public programs have been implemented to help the poor by transferring income to them. Since Lyndon Johnson's war on poverty began in 1964, over 3.5 trillion dollars have been transferred. However, the possibility that everyone, including the poor, may in fact be made worse off by the transfer has largely been ignored. With a simple algebraic model, the authors demonstrate that, over time, both high and low-income groups are harmed by redistribution. In addition, social mobility, as well as political concerns with relative poverty and international income redistribution increases the damage to all income groups produced by redistribution.     

信息、预期与动态均衡--对现代宏观经济学的一项研究

本文采用动态一般均衡的分析框架讨论现代宏观经济学及中国经济在发展中存在的一些问题。在70年的时间里,宏观经济学通过对信息、预期与市场均衡之间关系的把握,逐步形成了深刻揭示宏观经济特性的动态一般均衡框架,各种流派的理论均可以归结为在信息不完备条件下宏观经济如何实现动态一般均衡的理论,宏观经济学业已成为关于宏观经济长期动态均衡的理论。     

信息不对称条件下经济组织监管方式的分析:对我国公立医院改革模式的讨论

随着我国由计划经济体制向社会主义市场经济体制的过渡,仍然会有一定数量的国有医院要由国家直接控制经营。并需要相应的治理结构来规范其运行。本文的结果表明,在经济学理论上,公立医院的经营目的决定了产权改革既不是提高其经营绩效的充分条件,也不是必要条件。我们的理论分析否定了“产权优先”的改革观点,而为进一步完善公立医院治理结构的改革步骤提供了理论支持,并给出一定改革措施建议。另外,本文在理论上首次提出了非对称信息企业内部的“信息悖论”问题。这个广泛的结论不仅对于医院的改革是成立的,对于其他具有相同信息特征的企业都有理论意义。     

Fixed-Term Contracts and Labor Market Duality in France

The French labor market is segmented between permanent and temporary workers. The second category has difficulty in getting an open-ended contract. This paper aims at depicting workers on short-term contracts and shows the consequences on their professional career are negative and significant. A large part of the wage gap between permanent and temporary workers remains unexplained by observable characteristics. They receive less on-the-job training and their likelihood of obtaining a stable job is lower than 30% after 1 year and a half. They have also a higher probability of being the adjustment variable in case of an economic negative shock. These different findings show the importance of using public policies to encourage transitions from fixed-term to permanent employment and reducing labor-market duality.     

The Surge in Short-Duration Contracts in Spain

Until the outbreak of the recent economic and financial crisis, Spain was leading the ranking of countries with the largest share of temporary employees. During the crisis this share has fallen to its lowest level in decades, but this does not mean that working conditions in Spain have improved. The flow of new temporary contracts is larger than ever before. A particularly striking feature is the steep growth in the volume of fixed-duration contracts lasting less than a week or a month. We document these trends and analyse how this phenomenon has affected the transition from temporary to permanent employment.     

The Diffusion of Local Differentiated Waste Disposal Taxes in the Netherlands

The diffusion of a novel taxing scheme (among Dutch municipalities over the period 1998–2005) is studied in which the waste disposal tax is increasing in the amount of waste a household produces. Inspection of the rise and spread of this tax shows that it is contagious: the probability of introduction is increasing in the number of neighboring municipalities that have already introduced this taxing scheme. A possible rationale is that the tax encourages the dumping of waste in neighboring municipalities. These municipalities may then introduce a similar tax to prevent dumping (spillover effect). Using panel data and a recently developed spatial probit approach (Elhorst et al. in J Appl Econom 32:422–439, 2017), it is possible to distinguish this spillover effect from time-specific effects. The results indicate the presence of strong spillovers.
