THE IMPACT OF LABOR MARKET REGULATION ON EMPLOYMENT IN LOW‐INCOME COUNTRIES: A META‐ANALYSIS

Controversy over labor market policy often centers on achieving a balance between preventing worker exploitation, and avoiding loss of productivity or employment through excessive regulation. Although the literature documenting the impact of labor market regulation on employment is extensive, there is a dearth of evidence on the impact of such policies in low‐income countries (LICs). Since it is easier for workers, especially women, to slip into the informal sector in LICs, regulations are likely to have stronger impacts on formal employment in these countries (but lower impacts on unemployment). We systematically reviewed available research from countries that are, or were until recently, LICs. Most studies document that more stringent labor regulations are associated with lower formal sector employment and higher informal sector employment. We also conducted a metaregression analysis of the impact of minimum wages on formal and informal employment. After controlling for publication bias, higher minimum wages are associated with lower formal employment and a higher share of informal workers.     

Market imperfections and firm-sponsored training

Using worker and firm data from Dutch manufacturing, our paper investigates how product market competition and labor market imperfections affect firm-sponsored training. We find that product market competition does not affect the firms' training expenditures. Increasing competition, for instance due to increased international integration and globalization, is not a threat to investments in on-the-job training. Instead, labor market imperfections influence firm-sponsored training. An increase in labor market flexibility significantly reduces the incentives of firms to invest in training. The magnitude of this effect is nevertheless small.     

The impact of Medigap insurance on out-of-pocket health expenditures by older Americans over the 1980s

This study presents a comparative analysis of out-of-pocket health expenditures over the 1980s by older Americans with and without Medigap (supplemental) insurance. The objective is to analyze changes during the 1980s in the pattern of health expenditures and in the financing of those health expenditures by households age 65 and over. Two-stage regression analysis shows that health goods and services are normal goods. Out-of-pocket health expenditures, excluding insurance premiums, are higher for those with Medigap insurance, which may be explained by the market failures of moral hazard and adverse selection.     

Wages,implicit contracts,and the business cycle: Evidence from a European panel

We study the joint behavior of hours and wages over the business cycle in a unique panel of 13 European countries, and document significant history dependence in wages. Workers who experience favorable market conditions during their tenure on the job have higher wages, and work fewer labor hours. Unobserved differences in productivity, such as varying job quality, or match-specific productivity are not likely to explain this variation. The results instead point to the importance of contractual arrangements in wage determination. In economies with decentralized bargaining practices, such arrangements resemble self-enforcing insurance contracts with one-sided commitment (by the employer). On the other hand, in countries with strong unions and centralized wage bargaining, wage behavior is better approximated by full-commitment insurance contracts. The co-movement of hours and wages further confirms a contractual framework with variable worker hours. Despite the strong prevalence of contracts in Europe, however, the elasticity of labor supply is considerably smaller compared to the U.S. labor market.     

Search frictions,real wage rigidities and the optimal design of unemployment insurance

In this paper, we study the optimal unemployment benefits financing scheme when the economy is subject to labor market imperfections characterized by real wage rigidities and search frictions. The US unemployment insurance financing is such that firms are taxed proportionately to their layoffs to finance unemployment benefits. Using DSGE methodology, we investigate how policy instruments should interact with labor market imperfections. It is shown that wage rigidities in a search and matching environment cause welfare costs, especially in the absence of an incentive-based unemployment insurance. This cost is mainly due to the distorting effect of wage rigidities which generate inefficient separations. We show that the optimal unemployment benefits financing scheme – corresponding to the Ramsey policy – offsets labor market imperfections and allows implementation of the Pareto allocation. The second-best allocation brings the economy close to the Ramsey allocation. The implementation of the optimal policies clearly highlights the role of labor market institutions for short-run stabilization.     

Effects of Educational Expenditures on Regional Inequality in the Social Quality of Life

A bstract . Earlier studies by Liu on Quality of Life (QOL) indicators have pointed out the problems of concentration interregional inequality among the fifty states in U.S.A. Noting that the interregional inequality problem has been gradually alleviated over the past two decades, this paper attempts to provide some rudimentary explanations about this converging phenomenon through a labor market adjusting process towards social, economic and spatial equilibrium. Published state data and QOL indicators developed by Liu for 1960, 1970 and 1978 tend to support the hypothesis that investment in human resources , especially through improved elementary and secondary education , would enhance social mobility which would in turn improve labor and capital productivity. The reduced regional inequality in economic QOL seemed to be more a response than a cause when compared to that in social QOL, because variations in educational expenditures were found to be more significantly related to the social QOL indicators than to the economic ones.     

The effect of search frictions on wages

We aim to test whether the degree of informational search frictions in the labor market has a negative effect on wages. In a range of equilibrium search models of the labor market, this effect is predicted to be negative. Nevertheless, this has never been tested. We perform tests with matched worker–firm data. The worker data are informative on individual wages and labor market transitions, and this allows for estimation of the degree of search frictions. The firm data are informative on labor productivity. This allows us to investigate how the mean difference between labor productivity and wages in a market depends on the degree of frictions and other determinants, and to assess the quantitative relevance of frictions for wages.     

Homeowner Renovation and Repair: The Decision to Hire Someone Else to Do the Project

Renovation and repair expenditures are an important component of the U.S. housing market and have grown in importance relative to new construction as a source of housing supply. However, this aspect of the housing supply process is not well understood and the existing literature on the topic is relatively sparse. This paper focuses on one aspect of renovation and repair expenditures: the choice of a contractor job or a project mainly undertaken by the homeowner. The empirical work stresses the importance of looking at different categories of renovation expenditures separately. Household characteristics are important determinants of the homeowner's decision to hire someone else to do the work. Married couple households and other households with more adults are less likely to hire outside labor, all else equal. Higher household income and more years of education increase the probability of hiring outside labor. Black households have a significantly lower likelihood of performing their own renovations than white households with comparable characteristics and comparable housing units.     

Wages and the City. Evidence from Italy

We analyze empirically the impact of urban agglomeration on Italian wages. Using micro-data from the Bank of Italy's Survey of Household Income and Wealth for the years 1995, 1998, 2000 and 2002 on more than 22,000 employees distributed in 242 randomly drawn local labor markets, we test whether the structure of wages varies with urban scale. We find that every additional 100,000 inhabitants in the local labor market raises earnings by 0.1 percent. The use of a geographical approach enables us to state that this effect decays very rapidly with distance, losing significance beyond approximately 12 kilometers. We also find that urbanization does not affect returns to experience and that it reduces returns to education and to tenure with current firm, while providing a premium to worker supervisors.     

工资增长和个体异质性对养老保险再分配效应的影响

本文基于代表性的城镇职工养老保险抽样调查数据,分析工资增长和个体异质性对养老保险再分配效应的影响,研究“断保者”在现行制度下的损益。结果显示,高工资增长率增强了收入再分配的效果,降低养老保险参保者的基尼系数水平。通过对性别、户籍、劳动合同属性和行业的异质性分析发现,组间具有明显的收入再分配,户籍群体组间收入再分配最为显著。总体而言,持续参保对于非深圳户籍、农林牧渔业、制造业、建筑业、短期合同（劳务派遣）等“断保”高发人群是有利的。     

Wage incentives and wage rigidity: A representative view from within

A recent literature has used surveys of those who set wages to learn about the nature of wage incentives and the sources of wage rigidity. Methodologically, we overcome many of the objections that have been raised against this work. Substantively, we find that: (i) the reasons for real wage rigidity differ significantly between large and small firms, and between the high- and low-end of the labor market; (ii) efficiency wage mechanisms reinforce rigidities due to worker bargaining power; (iii) money illusion is a widespread phenomenon across all segments of the labor market; (iv) unions reinforce nominal wage rigidities due to external pay comparisons; (v) there appears to be gender differences in pay bargaining and work morale.     

Endogenous labor force participation and firing costs

I construct a matching model to explain the labor market transition between employment, unemployment and nonparticipation, and evaluate the quantitative effects of firing costs. The model has several features that are distinguished from previous studies: endogenous labor force participation, different job-search decisions and imperfect insurance markets. I find that the model is able to account for the U.S. labor market, especially the gross labor-force transition rates. I also find that firing costs as a type of firing tax have a negative effect on the layoff rate, the job-finding probability and the participation rate. In particular, the effect of a decrease in the job-finding probability is greater than the effect of a decrease in the layoff rate, and this results in an increase in the unemployment-to-population ratio. Finally, firing costs make individuals' job tenures longer and skew the asset distribution to the right.     

企业社会保险责任研究

我国企业社会保险责任源于法律的规定,具有正当性。同时,这种责任源于权利、社会期望、生存需要及劳动关系因而具有合理性。这种责任包括:为职工缴纳养老、医疗、工伤、失业、生育保险费;提供解除劳动关系的证明以及办理社会保险登记。但是,当前我国企业社会保险责任追究机制存在着职工个人社会保险救济程序单一、举证难、企业违法成本太低等问题,不足以约束企业履行其社会保险责任,必须予以完善。     

Household search and health insurance coverage

Health insurance in the United States is typically acquired through an employer-sponsored program. Often employees offered employer-provided health insurance have the option to extend coverage to their spouse and dependents. We investigate the implications of the “publicness” of health insurance coverage for the labor market careers of spouses. The theoretical innovations in the paper are to extend the standard partial–partial equilibrium labor market search model to a multiple searcher setting with the inclusion of multi-attribute job offers, with some of the attributes treated as public goods within the household. The model is estimated using data from the Survey of Income and Program Participation (SIPP) using a Method of Simulated Moments (MSM) estimator. We demonstrate how previous estimates of the marginal willingness to pay (MWP) for health insurance based on cross-sectional linear regression estimators may be seriously biased due to the presence of dynamic selection effects and misspecification of the decision-making unit.     

The role of asset testing in public health insurance reform

Starting slowly with the 1996 Welfare Reform Act and culminating in the 2010 Affordable Care Act, means-tested public health insurance eligibility expanded to include adults in low-income families regardless of their asset holdings. This paper quantifies the effects of these eligibility expansions within the context of the 2010 Affordable Care Act. I construct a dynamic stochastic general equilibrium model with indivisible labor supply expanded to include an endogenous household choice of health insurance coverage and calibrate it to U.S. data. I establish that changes in the distribution of labor and welfare associated with removal of asset testing are driven by exit of high productivity and high wealth households from the labor market. I then expand my analysis to the 2010 Affordable Care Act to demonstrate that removal of asset testing is critical to the obtained results even when combined with other provisions of the Act. Finally, I find that a simple asset test for eligibility of health insurance transfers undoes the distortion to the household labor supply decision among high productivity types. These results are robust to the introduction of employer premium contributions, an independent health insurance market, and idiosyncratic shocks to eligibility for employment-based health insurance.     

From Bismarck to Maastricht: The March to European Union and the Labor Compact

This paper considers the likely impact that European Union (EU) will have on the labor compact. It is argued that, despite increased economic integration in Europe, countries will still be able to maintain distinct labor practices if they are willing to bear the cost of those practices. The incidence of many social protections probably already falls on workers. In addition, it is argued that imperfect mobility of capital, labor, goods and services will limit the pressure that integration will place on the labor compact. Evidence is presented suggesting that labor mobility among EU countries has not increased after the elimination of remaining restrictions on intra-EU labor mobility in 1993. Moreover, immigration from non-EU countries, which is much larger than intra-EU migration, has declined since 1993. Evidence is also reviewed suggesting that the demand for social protection rises when countries are more open, and therefore subject to more severe external shocks. This finding suggests that increased economic integration and European Monetary Union (EMU) could lead to greater demand for social protection. The U.S. experience with state workers' compensation insurance programs is offered as an example of enduring differences in labor market protections in highly integrated regional economies with a common currency.     

Do environmental regulations hamper small enterprises' market entry? Evidence from China

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations.     

Language and urban labor market segmentation: Theory and evidence

I propose a language theory of labor market segmentation. People of different language origins form separate urban labor submarkets and can switch between submarkets. Two types of wage differentials emerge, namely the Within-Labor-Market Wage Gap and the Within-Language-Group Wage Gap. The average wage in each market and a worker’s choice of the labor market depend on the population sizes of the relevant groups. These implications are tested using the 2001 Census of Canada Public Use Microdata. A unique feature of these data is the reported work language, which helps me to identify labor market segments. The empirical evidence supports my theory.     

Worker poaching in a supply chain: Enemy from within?

Worker poaching represents the primary mode by which workers change employers. We examine worker poaching between firms linked in a value chain. We find that, in a value chain, the less productive firm may offer its workers higher wages and poach workers from the more productive firm. We also find that worker flows accomplished via poaching impact supply chain management: (a) the identity of the bottleneck firm may depend on whether poaching is available; (b) poaching between linked firms may benefit both, and (c) the value chain cannot be fully coordinated without controlling wages in the labor market.
