最低工资、就业弹性及就业效应研究

最低工资标准的提升对于就业的效应究竟是正是负,目前理论界并没有一致的论证结果。本文首先从市场结构和企业应对措施两个角度,梳理了西方学界关于最低工资对就业影响的作用机理,然后建立一个涉及农民工、企业和政府三方的博弈模型,推导出行业就业弹性对劳动参与的关键作用,并利用全国各省市六个行业的面板数据进行了实证分析。本文的主要结论是,最低工资的实施标准按行业设置比目前按地区＂一刀切＂的模式更具科学性。     

Synchronization and diversity in business cycles: a network analysis of the European Union

In this article, we use a correlation matrix and its internal networks to analyse business cycle synchronization across Europe since 2000. This methodology allows us to summarize individual country interactions and co-movements while also capturing the existing heterogeneity of connectivity within the European economic system. Our results indicate that synchronization of the euro zone countries remained stable from 1999 until the current financial crisis, after which co-movements increased sharply and synchronization rose to the highest in the time sample. By endogenously identifying clusters of countries with close connections in their business cycle, we also refute the commonly accepted notion of identifiable core and peripheral euro zone countries.     

The contribution of minimum wage valorization policy to the decline in household income inequality in Brazil: A decomposition approach

There is a vast literature that estimates the effect of the minimum wage on wage inequality in various countries. However, as the minimum wage directly affects nonlabor income of families in some countries (in the Brazilian case via the benefits of the pension system and of certain social programs), this article extends the empirical analysis by studying the effects of the minimum wage on the level of inequality of household income as a whole. To accomplish that we employ a decomposition method that gauges the contribution of the increases in the minimum wage that occurred in recent decades in Brazil through the labor and nonlabor sources of household income. The results show that the minimum wage had a contribution of 64 percent to the observed fall in income inequality between 1995 and 2014 and that pensions were the most relevant channel over this period.     

失地农民低保制度建设的分析探讨

伴随着城市化的步伐,承包给农民的部分农村集体土地被征用,不少失地农民因此成为"种田无地,上班无岗,低保无份"的"三无"人员。目前全国各地针对失地农民中的贫困者的制度设计和救助水平不同,由此也对低保制度构成挑战,这其中有制度性原因,也有地方规划等政策导向因素。总体来说,将贫困失地农民纳入城市低保制度体系是社会发展的趋势,需要从调整土地安置政策、加强全面的社会救助制度、加强社会管理等方面来解决贫困失地农民的生存和发展问题。     

Market Liberalization,Regulatory Uncertainty,and Firm Investment

This paper analyzes the effects of regulatory uncertainty regarding labor costs on investment in a liberalized market. We distinguish between the external investment margin (market entry) and the internal investment margin (technology), and establish that regulatory uncertainty affects these margins differently, encouraging market entry, but discouraging technological investment. As a consequence, the impact of regulatory uncertainty on competition in liberalized markets is a combination of these two countervailing forces.     

Does china income FSDs follow Benford? A comparison between Chinese income first significant digit distribution with Benford distribution

Since Benford’s law is an empirical phenomenon that occurs in a range of data sets, this raises the question as to whether or not the same thing might be true in terms of the Chinese income distribution data. We focus on the first significant digit (FSD) distribution of Chinese micro income data from the 2005 Inter-Census sample, which corresponds to 1% of Chinese population and other micro income data from the China family panel studies (CFPS) and Chinese General Social Survey (CGSS). We use information theoretic-entropy based methods to investigate the degree to which Benford’s FSD law is consistent with the FSD of Chinese income data and our findings suggest consistency between the Chinese FSD income distribution and Benford’s distribution. The close connection between the two distributions has implications for the quality of the sample of Chinese micro data.

我国最低工资的制度逻辑——一个政治经济学的解读框架

最低工资制度从诞生时起就备受争议.主流经济学家反对的主要理由是,最低工资是对劳动力市场的价格管制,会导致失业率上升,经济效率下降.尽管这一结论并未完全得到实证检验的支持,但是作为一个正在崛起的发展中大国,效率和就业自然是我们首要关注的.理论和现实说明,我国目前并不具备最低工资的实施环境,那么政府为什么还要推行最低工资制度呢?本文提供了一个政治经济学的解读框架.     

低保制度是地方性公共服务吗?

本文从公共经济学的视角,分析了低保制度的属性,明确指出低保制度应是全国性公共服务而不是地方性公共服务,阐述了低保制度属于全国性公共服务的现实意义有助于明确中央政府在低保制度建设中的职责、有助于实现基本公共服务均等化、有助于推进社会保障城乡统筹;同时在低保制度是全国性公共服务的框架下,探讨了农村低保制度的供给问题。     

The minimum approval mechanism implements the efficient public good allocation theoretically and experimentally

We propose the minimum approval mechanism (MAM) for a standard linear public good environment with two players. Players simultaneously and privately choose their contributions to the public good in the first stage. In the second stage, they simultaneously decide whether to approve the otherʼs choice. Both contribute what they choose in the first stage if both players approve; otherwise, both contribute the minimum of the two choices in the first stage. The MAM implements the Pareto-efficient allocation in multiple solution concepts including backward elimination of weakly dominated strategies (BEWDS), limit logit agent quantal response equilibrium, subgame perfect minimax regret equilibrium, level-k thinking, and diagonalization heuristics. Moreover, the MAM is unique under plausible conditions. Overall, contributions in the MAM experiment averaged 94.9%. Quantifying subjectsʼ responses to the questionnaire reveal heterogeneous reasoning processes and highlight the importance of developing mechanisms that implement the desired social choice outcome in multiple solution concepts.
