论我国企业债券市场发展滞后的供求基础

我国企业债券市场发展滞后是多种因素综合作用的结果,总体表现为供给不足、需求无法满足、市场体系不完善、相关制度和机构不健全、缺乏创新.影响我国企业债券市场发债滞后的供给和需求最根本的原因在于体制性制约、政府在引导投资流向上计划经济色彩过浓,没有随着经济形式的变化进行相应的改革和创新.

中国上市公司资本结构调整能力的实证研究

以1992—2002年为观测区间,沪、深股市A股市场的所有上市公司为样本,采用FamaMacbeth方法研究我国上市公司资本结构的调整。我们发现,在短期(一年内),上市公司的资本结构变动有近三分之一的原因来自股票市场的波动,上市公司的资本结构会出现向历史比率温和调整的趋势;将观测区间延长至三年时,股票收益的波动对上市公司资本结构变动的影响减弱,资本结构向历史水平调整的力度明显加大。同时,在动态调整过程中,上市公司主动调整资本结构的手段只能依赖负债的主动调整。     

经济转型中的劳动合同期限和试用期

利用最新的调查数据,研究了经济转型过程中的劳动合同期限和试用期.研究发现,员工的教育程度和工作经验等个人特征,企业在产业分包体系中的层级和应用的创新性工作实践的数量等企业特征,显著地影响了企业在劳动合同期限和试用期上的决策;经济转型提升了企业雇佣决策的合理性;劳动力市场改革、劳动力市场供求状况的变化以及产品市场竞争程度的加剧是导致劳动合同期限短期化的主要原因.

Shifts in the employment outcomes among Mexican migrants to the United States, 1976–2009

Although studies have examined the impact of U.S. immigration policy shifts in the 1980s and 1990s on the employment outcomes of migrants, scholars have paid less attention to how the federal government's shifting approach to worksite enforcement has transformed the conditions in which Mexican migrants work. Consistent with previous research, we find a worsening of conditions for both unauthorized and legal Mexican migrants in the years following the passage of the Immigration Reform and Control Act (IRCA) and that unauthorized status is associated with more unfavorable workplace conditions relative to legal immigrants. However, in the first decade of the 21st century, we also find that unauthorized immigrants’ employment outcomes more closely resemble those of legal immigrants now than in the past, suggesting a dramatic shift in the ways that employers treat unauthorized immigrants on the job. This convergence between authorized and unauthorized migrants is consistent with federal policies and practices related to workplace enforcement.     

Strategic Supply Function Competition With Private Information

A finite number of sellers (n) compete in schedules to supply an elastic demand. The cost of each seller is random, with common and private value components, and the seller receives a private signal about it. A Bayesian supply function equilibrium is characterized: The equilibrium is privately revealing and the incentives to rely on private signals are preserved. Supply functions are steeper with higher correlation among the cost parameters. For high (positive) correlation, supply functions are downward sloping, price is above the Cournot level, and as we approach the common value case, price tends to the collusive level. As correlation becomes maximally negative, we approach the competitive outcome. With positive correlation, private information coupled with strategic behavior induces additional distortionary market power above full information levels. Efficiency can be restored with appropriate subsidy schemes or with a precise enough public signal about the common value component. As the market grows large with the number of sellers, the equilibrium becomes price‐taking, bid shading is on the order of 1/n, and the order of magnitude of welfare losses is 1/n². The results extend to inelastic demand, demand uncertainty, and demand schedule competition. A range of applications in product and financial markets is presented.     

中国人口回旋空间在构建新发展格局中的优势和作用

面对世界百年未有之大变局、全球新冠肺炎疫情的冲击和国际发展环境不确定性增大,党中央提出了要加快构建以国内大循环为主体、国内国际双循环相互促进的新发展格局。构建和形成新发展格局中需要更加综合的视角考虑中国人口规模、年龄结构、人力资本及人口空间分布等因素在经济高质量发展中的作用和独特优势。中国拥有的巨大人口规模所形成的巨大市场效应,有利于促进和带来社会分工精细化从而促进经济增长;巨大的人口规模可以为经济社会发展提供稳定而充足的有效劳动供给、人力资本和人才储备;巨大的人口规模也为技术创新和进步提供人力资本支撑以及市场需求条件;同时可以充分利用中国广袤的空间回旋优势、利用区域间发展差异特征,实现产业优化升级和梯次转移,保持产业体系的完整和协调发展,优化人力资源与自然资源禀赋的配置。因此,即便在人口老龄化和人口负增长背景下,只要充分发挥人口规模巨大在总供给和总需求、内需和外需、投资和消费、出口和进口等环节的联通枢纽作用,必能畅通国内大循环和国内国际双循环相互促进,从而保障经济实现高质量发展。
