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。     

最低工资对中国就业和工资水平的影响

本文以1998—2007年全国各市(地区、自治州、盟)最低工资标准随时间变化的外生差异来识别最低工资上涨与企业平均工资、企业雇佣人数的关系。利用1998—2007年规模以上制造业企业报表数据进行的分析显示,最低工资每上涨10%,制造业企业平均工资将整体上涨0.4%—0.5%。借助2006—2007年福建省最低工资上涨的"准自然实验"本文也证实了该结论。对于不同行业、不同人均资本水平的企业,最低工资上涨的影响也存在异质性。最低工资将更多地增加劳动密集型或人均资本较低企业的平均工资。研究还发现,最低工资每增加10%,制造业企业雇佣人数将显著减少0.6%左右。政府在制定最低工资时应权衡其在收入分配上的积极效果以及其对就业的负面影响。     

The Effects of Germany's Statutory Minimum Wage on Employment and Welfare Dependency

In January 2015, Germany introduced a federal, statutory minimum wage of 8.50 € per hour. This study evaluates the effects of this policy on regular and marginal employment and on welfare dependency. Based on the county‐level administrative data, this study uses the difference‐in‐differences technique, exploiting regional variation in the bite of the minimum wage, i.e., the county‐specific share of employees paid less than 8.50 € before the introduction of the minimum wage. The minimum wage had a considerable negative effect on marginal employment. There is also some indication that regular employment was slightly reduced. Concerning welfare dependency, the minimum wage reduced the number of working welfare recipients, with some indication that about one half of them left welfare receipt due to the minimum wage.     

劳动力异质性与中国最低工资标准就业效应分析

最低工资是当今世界各国广泛应用的经济政策,也是经济学家关心的议题。我国的最低工资标准偏低,且执行程度欠佳,所以我国的最低工资覆盖情况实际上符合部分覆盖的假设。同时由于我国劳动力的异质性以及最低工资制度的实施,导致未覆盖部门的低技能劳动力就业增多,而覆盖部门的高技能劳动力就业比例增多,总的就业效应方向并不明确。     

北京市最低工资制度实施状况与就业影响中介效应分析

文章评估了北京市最低工资制度的实施状况,并采用中介效应法分析最低工资的就业效应及其内在作用机制。作者研究发现:一是最低工资对建筑业就业产生负效应;二是建筑行业最低工资的就业负效应,部分是通过技术装备率的中介效应实现的,最低工资增长促使企业用资本替代劳动,最终影响就业水平。其它原因可能是建筑企业直接减少招聘、裁员来应对人工成本上涨;三是最低工资促进了劳动生产率提高,并没有作用于就业水平。     

我国最低工资的就业效应及其作用机制——基于建筑业面板数据的研究

本文运用我国30个省、市、自治区建筑业1995～2006年的面板数据,研究发现最低工资对我国建筑业就业存在显著的负效应,大致为最低工资每增长10个百分点,将导致建筑业就业水平下降1.3个百分点.进一步地,本文基于中介效应模型探讨最低工资就业效应的作用机制,研究发现最低工资的就业负效应主要是以直接效应的形式表现的,即企业以减少或冻结招聘甚至减员来应对最低工资增长的冲击;同时,最低工资还通过促使企业用资本替代劳动、提高劳动生产率方式间接导致就业岗位的减少.而由于我国技术工人比例显著偏低,因此企业无法用技术工人替代相对不经济的普通操作工人的办法来应对最低工资增长.     

Effects of Local,State, and Federal Minimum Wage on Employment Growth among Teenagers in the Restaurant Industry

Over the last 20 years, local municipalities have been implementing minimum wage ordinances at an accelerated rate. These local changes, along with state and federal minimum wage increases, are included in the examination of the impact of minimum wage hikes on employment growth of teenagers in the food services and drinking places subsector. While most minimum wage research focuses on employment levels, recent contributions highlight the importance of analyzing employment growth. Following this trend, this study focuses on teenagers within the restaurant industry to test for the impact of minimum wages on inexperienced workers. Using a distributed-lag model, the results show that an increase in a minimum wage reduces employment growth for teenagers within this subsector. The effects of minimum wages within this demographic were most strongly felt in the first three years following an increase in minimum wage. Specifically, the results show that a 10% increase in the minimum wage decreases the employment growth rate by approximately 2.27% over a period of three years.

     

Wage Posting in Two-Sided Search and the Minimum Wage

This article focuses on wage formation in an equilibrium (two-sided) model of search with match-specific heterogeneity. Despite a large number (a continuum) of employers, search provides sufficient isolation to generate market power. By posting wages, employers, without collusion, capture most of the surplus that accrues to any match. The equilibrium wage is below that which maximizes employment. An example, using calibrated parameter values, is used to reconcile some recent, otherwise contradictory empirical results on the employment effects of minimum wage adjustments.     

The Minimum Wage and the Cause of Democracy

Too often the minimum wage is conceived of as a small policy measure that will be of benefit to only a small segment of the labor market while imposing costs on another segment of the labor market. Unexplored, however, are the larger philosophic questions that such a small measure may actually raise. One such issue is the relationship between the minimum wage and democratic principles. In this paper I argue that the minimum wage furthers the ends of democratic society in that low-wage workers may achieve greater equality of standing with their piers to the extent that income inequality is at all lessened; their autonomy as individuals is enhanced through higher wages, which in turn enables them to claim the benefits of citizenship and participate more effectively in the democratic process; and it fosters greater economic development in that it raises the overall structure of a region and perhaps the productivity of that region.     

The Welfare and Employment Effects of Centralized Public Sector Wage Bargaining

In many countries, the government pays almost identical nominal wages to workers living in regions with notable economic disparities. By developing a two‐region general equilibrium model with endogenous migration and search frictions in the labor market, I study the differences in terms of unemployment, real wages, and welfare between a regional wage bargaining process and a national one in the public sector. Adopting the latter makes residents in the poorer region better off and residents of the richer region worse off. Private sector employment decreases in the poorer region and it increases in the richer one. Under some conditions, the unemployment rate in the poorer region soars.     

Teaching the Minimum Wage in Econ 101 in Light of the New Economics of the Minimum Wage

The author argues that the recent controversy over the effect of the minimum wage on employment offers an opportunity for teaching introductory economics. Research findings on the minimum wage could be used to motivate alternative models of the labor market, such as monopsony and search models, and to teach students how economists test hypotheses with data.     

Economics and the Supreme Court: The Case of the Minimum Wage

In the United States, laissez-faire has been the policy advocated in good times, while social legislation has been called for during crises. One instance of this dichotomy concerns the transformation of the American understanding of minimum wage laws during the early 20^th century. During this time, the view of minimum wage laws changed from one that viewed such laws as theft, to one that saw such laws as being required for distributional justness. We examine the legal-historical debate concerning whether the Supreme Court renounced its policy of laissez-faire individualism in its 1937 ruling finding the minimum wage law constitutional, arguing that it did not. We investigate the free market standard that the Court used to find minimum wage laws unconstitutional in 1923. We demonstrate how the economic conditions of the Depression, coupled with the development of economic theory, explain how the Court eventually found the minimum wage law constitutional.     

最低工资标准的就业效应研究--基于30个省际面板数据的实证分析

通过构建一个由最低工资标准等因素共同决定的劳动力就业函数,从理论层面分析最低工资标准提升等因素对城镇劳动力就业的影响。同时基于中国2004_2011年的省际面板数据,引入技术进步、城镇化、老年抚养比等指标,运用面板分位数回归方法进行实证分析。综合比较来看：现阶段最低工资标准提升与城镇劳动力就业呈显著正相关关系,而技术进步对城镇劳动力就业的影响不能一概而论,具有不确定性。其他控制变量如城镇化发展有利于提高城镇劳动力就业,而老年抚养比、对外开放度的提高却与城镇劳动力就业呈负相关关系。其对策含义为：要充分考虑相关因素对劳动力就业的冲击,理清不同地区、不同企业类型以及不同性别可能存在的有差异的劳动力就业效应,主张通过就业政策和劳动力市场制度的进一步完善,实现劳动力更加充分的就业。     

The Redistributive Effects of a Minimum Wage Increase in New Zealand: A Microsimulation Analysis

This paper examines the potential effects on inequality and poverty of a minimum wage increase, based on a microsimulation model that captures the details of household composition and the income tax and welfare benefit system and allows for labour supply responses. Results suggest that, largely due to the composition of household incomes, a policy of increasing the minimum wage has a relatively small effect on the inequality of income per adult equivalent person, and a money metric utility measure, using several inequality indices. Hence, the minimum wage policy does not appear to be particularly well targeted, largely due to many low wage earners being secondary earners in higher income households, while many low income households have no wage earners at all. These results are reinforced when allowing for wage spillovers further up the wage distribution. Nevertheless, a minimum wage increase can have a more substantial effect on some poverty measures for sole parents in employment.     

The Economics and Ethics of Minimum Wage Legislation

Recent empirical studies have led the economics profession to question the proposition that minimum wage legislation necessarily leads to greater unemployment. This paper extends the analysis of these studies by providing several theoretical reasons why these empirical results may reflect a larger truth. Moreover, it addresses a relatively neglected aspect of the minimum wage debate - its ethical dimensions. Specifically, do the elementary principles of economic justice mandate that employees who “play by the rules”, should earn a “living wage”? This paper argues that the minimum wage is a successful economic policy that is consistent with economic justice.     

The Low Pay Commission and the National Minimum Wage

Great Britain has had statutory regulation of minimum pay for most of this century but never previously had a national minimum wage (NMW). This paper outlines the history of minimum wage regulation culminating in 1997 with the establishment of the Low Pay Commission (LPC). The three key debates within the LPC are analysed, namely the definition of the wage, what to do about youngsters, and the level to set the NMW. The impact of the NMW on the pay distribution, employment, family incomes and exchequer finances is set out. The paper concludes that the LPC is a fine example of successful social partnership.     

The Causal Effects of the Minimum Wage Introduction in Germany – An Overview

In 2015, Germany introduced a statutory hourly minimum wage that was not only universally binding but also set at a relatively high level. We discuss the short‐run effects of this new minimum wage on a wide set of socioeconomic outcomes, such as employment and working hours, earnings and wage inequality, dependent and self‐employment, as well as reservation wages and satisfaction. We also discuss difficulties in the implementation of the minimum wage and the measurement of its effects related to non‐compliance and suitability of data sources. Two years after the minimum wage introduction, the following conclusions can be drawn: while hourly wages increased for low‐wage earners, some small negative employment effects are also identifiable. The effects on aspired goals, such as poverty and inequality reduction, have not materialised in the short run. Instead, a tendency to reduce working hours is found, which alleviates the desired positive impact on monthly income. Additionally, the level of non‐compliance was substantial in the short run, thus drawing attention to problems when implementing such a wide reaching policy.     

The Dynamics of Poverty and the Promotion of Transition from Non‐Regular to Regular Employment in Japan: Economic Effects of Minimum Wage Revision and Job Training Support

Comparison between Japan and other advanced countries shows that the relative poverty rate is high in Japan, and that many of the poor households are those with a non‐regular worker. As for mobility between income classes, the proportion of households remaining in the poor class for a long period of time in Japan is close to the average for EU countries. The panel estimation of its effect on wages shows that the raising of the minimum wage is statistically significantly associated with an increase in wages of non‐regular workers, in particular, female, but does not seem to decrease employment. The result shows that for male non‐regular workers, firm‐provided training promotes their transition to regular employment, and that for female non‐regular workers, occupational training promotes their transition to regular employment at different firms.
