Changes in the structure of earnings during the Polish transition

We document changes in the structure of earnings during the economic transition in Poland. We find that inequality in labor earnings increased substantially from 1988 to 1996. A common view is that the reallocation of workers from a public sector with a compressed wage distribution, to a private sector with much higher wage inequality, accounts for the bulk of increased earnings inequality during transition (see, e.g., the models of Aghion and Commander (1999) [Aghion, Philippe, Commander, Simon, 1999. On the dynamics of inequality in the transition. Economics of Transition 7, 275–2898.] and Commander and Tolstopiatenko (1998) [Commander, Simon, Tolstopiatenko, Andrei, 1998. The role of unemployment and restructuring in the transition. In: Commander, Simon (Ed.), Enterprise Restructuring and Unemployment in Models of Transition. The World Bank, Washington, pp. 169–192.]). However, our decomposition of the sources of the increase in inequality suggests that this compositional effect accounts for only 39% of the increase. Fully 52% of the increase is due to the increase in the variance of wages within sectors. That is, earnings inequality within both the private and public sectors grew substantially, and by similar amounts. This is consistent with prior work suggesting that even state-owned enterprises in Poland moved towards competitive wage setting as they restructured (see, e.g., Pinto et al. (1993) [Pinto, Brian, Belka, Marek, Krajewski, Stefan, 1993. Transforming state enterprises in Poland: evidence on adjustment by manufacturing firms. Brookings papers on Economic Activity, 213-70.] Commander and Dhar (1998) [Commander, Simon, Dhar, Sumana, 1998. Enterprises in the Polish transition. In Simon Commander (Ed.), Enterprise Restructuring and Unemployment in Models of Transition. The World Bank, Washington, pp. 109-142.]).A substantial part of the increase in earnings inequality was between group, due largely to increased education premiums. However, changes in inequality within education–experience–gender groups account for about 60 percent of the increase in overall earnings inequality. The increases in within-group inequality were very different across skill groups, with much larger increases for highly educated workers. These patterns hold in both the private and public sectors, although increases in education premiums were somewhat greater in the private sector.     

外资企业对中美贸易顺差影响的实证分析

自1993年中关贸易出现顺差以来,贸易差额持续扩大,由于利益集团的推动,美方借口中关贸易巨额赤字问题对人民币汇率、知识产权等问题频频横加指责。在分析中关贸易顺差问题时有必要深入探讨外商在华直接投资与中关贸易顺差的关系,这有助于帮助我们更好地认识、处理和发展双方经贸关系。     

改革开放30年:保险业的嬗变及发展路径的审视

我国保险业从1980年恢复至今,伴随改革开放的不断深入和国民经济的迅速发展,从无到有、从弱到强,取得了巨大的发展。在市场全面开放、竞争日趋激烈的背景下,特别是在当前国际金融危机的大背景下,本文总结了保险业近30年发展的经验教训,以期为推动保险业实现增长方式的转变、提升国际竞争力、实现长期、可持续发展提供理论指导。     

二元经济中城乡混合基尼系数的计算与分解

关于基尼系数计算方法的文献已经十分丰富,但专门计算城乡混合基尼系数的理论方法,却一直没有得到很好的解决,这导致全国收入分配长期变化方面的某些研究难以深入。本文建立了城乡混合基尼系数的新算法,并给出新的分解形式,同时还提出并论证了度量城乡差距的新指标。该分解形式具有明确的经济含义和理论意义,并且不依赖于“城乡收入分布不重叠”的假定。利用这一分解形式的经济含义,我们分析了几个重要理论问题。最后,应用新算法计算并分解了中国个别年份的城乡混合基尼系数,以检验新算法的有效性。     

双城互动:天津迈向北方经济中心的空间重构

1990年代开始,新区建设逐步成为各城市提升竞争力、推进工业化和城镇化的重要手段。天津是通过滨海新区建设带动城市和区域发展的典型。文章主要分析在滨海新区开发开放上升为国家战略的背景下,天津重新调整空间发展思路,通过实施"双城"空间发展战略,实现新旧区良性互动协调发展。     

基于谱分析的中美利率波动周期比较

论文以1954年7月1日以来美国联邦基金利率及2006年10月8日以来上海银行间同业拆借利率隔夜品种为观察对象,运用谱分析方法研究中美两国利率的周期特征及周期波动的位相关系。单谱分析结果显示,美国联邦基金利率存在着20年左右、8年～11年、2～4年的周期特征。以本文的观察角度,两国利率均存在2年、1年半、1年左右及半年左右的周期特性,有相似的周期特征。交叉谱分析表明,美国联邦基金市场与上海银行间同业拆借市场的波动互有领先。     

校企合作在西部普通高校全日制硕士专业学位创新培养中的功能与实践

论文提出西部普通高校是全日制硕士专业学位教育的主要力量,但是培养资源匮乏是制约西部普通高校全日制硕士专业学位健康和可持续发展的瓶颈环节。应利用企业资源,提高全日制硕士专业学位培养质量,并提出了校企合作的作用与内容。     

台湾农产品贸易的困境与出路

近年来,台湾试图通过扩大农产品外销目标市场、建立以外销为导向的“安全农业”产销体系和国际行销资讯网等措施寻找出路。鉴于两岸源远流长的文化根基和20多年来经贸交往的良好基础,大陆正成为台湾拓展农产品贸易空间的必然选择。     

财政支出结构与城乡收入差距——基于东、中、西部地区省级面板数据的经验分析

本文基于中国三大地区的省级面板数据,构建计量模型,实证考察财政支出结构对城乡收入差距的影响。实证结果表明,政府财政支出结构对城乡收入差距有显著影响,不同财政支出项目的影响方向不同,且财政支出结构对城乡收入差距的影响在中国三大地区存在差异性。因此,研究财政支出结构对城乡收入差距的影响,不能仅就全国范围考察,还需分区域进行。本文最后根据实证结果提出了一些缩小城乡收入差距的政策建议。
