Effect of labor market policies on unemployment when firms adapt their recruitment strategy

Firms conduct interviews to select who to hire. Their recruitment strategies affect not only the hiring rate but also job destruction rate as more interviews increase the chances of finding the right worker for the job; a link mostly overlooked in the literature. I model this recruitment behavior and investigate the effects of labor market policies on unemployment. These policies change the value of hiring the right worker, altering firms' incentives to conduct interviews. Policies further affect job creation and destruction when firms adapt their recruitment strategies. Net effect of a policy on unemployment depends on the magnitude of change in job creation versus destruction. Qualitative analysis reveals that the effect of a policy on unemployment is mostly weakened with the introduction of firms' recruitment behavior to the model. Firing taxes still increase unemployment, albeit at a lower rate. The effect of hiring subsidies on unemployment is even reversed: Unemployment increases with hiring subsidies if firms adapt. Minimum wage and unemployment insurance policies are also analyzed.     

Labor market search, sticky prices, and interest rate policies

What accounts for the significant real effects of monetary policy shocks? And what accounts for the persistent and hump shaped responses of output and inflation in response to such shocks? These questions are investigated in a model that incorporates labor market search, habit persistence, sticky prices, and policy inertia. While habit persistence and price stickiness are important for the hump shaped output response and the long, drawn out inflation response, respectively, labor market frictions increase the output response and reduce the inflation response relative to an otherwise similar model based on a Walrasian labor market. Significantly, policy inertia itself is found to be the most important factor in accounting for the magnitude of the output effects of policy shocks in the model.     

Land collateral and labor market dynamics in France

The value of land in the balance sheet of French firms correlates positively with their hiring and investment flows. To explore the relationship between these variables, we develop a macroeconomic model with firms that are subject to both credit and labor market frictions. The value of collateral is driven by the forward-looking dynamics of the land price, which reacts endogenously to fundamental and non-fundamental (sunspot) shocks. We calibrate the model to French data and find that land price shocks give rise to significant amplification and hump-shaped responses of investment, vacancies and unemployment that are in line with the data. We show that both the endogenous movements in the firms׳ discount factor and the sluggish response of the land price are key elements that drive the results.     

二元经济结构下最低工资的就业效应研究——基于劳动力市场的视角

现阶段我国整体就业形势不容乐观,分析最低工资对就业的影响具有重要的现实意义。通过对我国劳动力市场分割条件下最低工资的就业效应进行实证分析发现,最低工资对竞争性行业劳动力市场（城市二级劳动力市场）就业有显著的正面影响,对行政垄断行业劳动力市场（城市一级劳动力市场）就业的正面影响则很小。因此,根据我国劳动力市场的具体情况,合理设置最低工资标准有利于促进就业。     

Regulation of entry, labor market institutions and the informal sector

This paper develops a two-sector matching model that incorporates the main features of Latin American labor markets. It has an innovation in its matching structure that makes it more consistent with some key stylized facts of the informal sector in these countries. The model is numerically solved using Brazilian data and several policy simulations are performed. Reducing formal sector's entry cost significantly reduces the size of the informal sector and improves overall labor market performance. Increasing enforcement significantly reduces informality but has strong adverse effects on unemployment and welfare. Thus, the results indicate that the tradeoff between lower informal employment and higher unemployment rates is not present when one looks at policies that aim at reducing the costs of being formal, as opposed to policies that simply increase the costs of being informal.     

解决劳动力市场歧视问题之对策

Social Security and Old Age Unemployment Risk with Efficient Wage Bargaining

I analyze a life‐cycle economy with old age productivity risk where wages, employment, and severance payments are set through efficient bargaining between risk averse unions and risk neutral firms. Allocations with limited union membership are second‐best inefficient as they generate too little labor supply in young age, too much consumption before retirement, too little employment of older workers (early retirement), and too little insurance against old age unemployment. Providing public transfers to early retirees (disability benefits or early pensions) might help to increase the degree of risk sharing at the cost of lower old age employment. Depending on whether absolute risk aversion is increasing or decreasing in consumption, these policies might or might not produce efficiency gains at equilibrium.     

Mineral endowment, labor productivity, and comparative advantage in mining

Labor productivity in the U.S. copper mining industry tripled between 1975 and 1995, allowing the industry to recover its comparative advantage. Mine level data on output and labor input indicate that over three-quarters of this increase came from labor productivity growth at individual mines, and less than a quarter from shifts in output from low- to high-productivity mines. This finding supports the hypothesis that new technology and innovation are as important or more important than mineral endowment in shaping labor productivity trends and comparative advantage in mining.     

劳动力市场行政垄断行业分割与劳动收入比重——基于中国省级面板数据的分析

通过对我国劳动收入比重变动的原因研究发现:劳动力市场行政垄断行业分割与劳动收入比重之间互为因果。我国劳动力市场行政垄断行业分割会使行政垄断行业就业人数占总就业人数比例下降,行政垄断行业和竞争行业间收入差距扩大,导致劳动收入比重下降,进而会使资本实际价格下降,增强行政垄断企业的市场力量,加剧劳动力市场行政垄断行业分割程度。因此,减弱劳动力市场行政垄断行业分割是稳定劳动收入比重的关键。     

Are cadre offspring in the fast lane? Evidence from the labour market for college graduates in China

This paper studies the impact of having a cadre parent on the labour market performance and channels of the intergenerational transference. Using a recent data set, we find that college graduates with a cadre parent earn a wage premium of 4.46% more than those who do not. They also demonstrate advantages in obtaining a household registration (hukou), entering high-level occupations, and achieving job satisfaction. In the discussion on channels, we first show that aggressive self-investment serves as one potential channel but can only explain limited amount of the premiums. To test the other channel – interpersonal network (guanxi), we provide evidence that cadre offspring demonstrate more extensive family network resource and information advantage when searching for jobs. This channel is also supported by the finding that working closer to parents geographically or institutionally would enhance the effect of having a cadre parent.     

Families and firms: Agency costs and labor market imperfections in Sialkot's surgical industry

The family firm is generally viewed as an organizational solution to agency costs in the labor market for managers and institutional underdevelopment. Consistent with this view, this paper links the preponderance of family firms in the surgical instrument industry of Sialkot to the prevailing agency and institutional problems. However, strong dependence on family management coupled with restrictions on family size constrains the firms from optimally choosing management size. The resulting labor market distortion is manifested by a significant positive correlation between the founder's family size and the firm size such that the founders who have more brothers (a larger pool of potential managers) end up with bigger firms.     

Bargaining frictions, labor income taxation, and economic performance

This paper is an attempt to explain differences in economic performance between a subset of OECD countries. We classify countries in terms of their degree of rigidity in the labor market, and use a matching model with labor/leisure choice, bargaining frictions, and labor income taxation to capture these rigidity differences. Added flexibility improves economic performance in different ways depending on whether income taxation is high or low. Feeding income taxation rates estimated from the countries at hand, we find that the model is able to replicate the observed rigidity levels. The model is also shown to reproduce well cross-country differences in non-employment population ratios and the share of part-time jobs. In the absence of rigidity differences, taxation shows little promise to replicate cross-country differences, as it has insufficient quantitative effects on production and productivity. However, the interaction of rigidity and income taxation is crucial in explaining the empirical patterns of the non-employment rate and of the share of part-time jobs.     

Job Creation and Job Destruction in a Regulated Labor Market: The Case of Austria

We study Austrian job reallocation in the period of 1978 to 1998, using a large administrative dataset where we correct for spurious entries and exits of firms. We find that on average 9 out of 100 randomly selected jobs were created within the last year, and that about 9 out of randomly selected 100 jobs were destroyed within the next year. Hence, the magnitude of Austrian job flows seems to be comparable to other countries, similar to the well-known results of Davis et al. (1996) for the United States. Job reallocation appears to be driven primarily by idiosyncratic shocks. However, job creation increases significantly during cyclical upswings whereas job destruction rises in downturns. We also find substantial persistence of job creation and destruction. The pronounced pattern of job reallocation rates falling with firm size and age continues to hold when we use a set of controls. Finally, we show that – controlling for sector and firm size composition – Austrian job reallocation rates are only half the rates for the U.S. This result is not surprising given the impact of tighter regulation and labor law in Austria.     

The labor market impact of immigration in Western Germany in the 1990s

In this article we estimate the wage and employment effects of recent immigration in Western Germany. Using administrative data for the period 1987-2001 and a labor-market equilibrium model, we find that the substantial immigration of the 1990s had very little adverse effects on native wages and on their employment levels. Instead, it had a sizeable adverse employment effect on previous immigrants as well as a small adverse effect on their wages. These asymmetric results are partly driven by a higher degree of substitution between old and new immigrants in the labor market and in part by the rigidity of wages in less than flexible labor markets. In a simple counter-factual experiment we show that in a world of perfect wage flexibility and no unemployment insurance the wage-bill loss of old immigrants would be much smaller.     

Gender Segregation and Income Differences in Nicaragua

Despite having higher average education levels, Nicaraguan women still earn much less than men. Furthermore, the country has one of the highest levels of occupational gender segregation in Latin America. This paper aims to explain the gender income gap in Nicaragua, taking into account individual characteristics, engagement in specific occupations and sectors, and geographical location. Using a multilevel framework, the study finds that while a considerable part of the income gap can be explained by women’s employment in occupations and sectors with low remuneration, another substantial part of this gap is attributable to the prevalence of patriarchal gender norms – and thus cannot be explained by human capital factors. These results show that understanding labor market segregation is vital for comprehending the perseverance of the gender income gap, and they further imply that women’s progress in breaching the gender stereotypes in Nicaragua is still limited.     

Distributional assumptions and a test of the dual labor market hypothesis

Recent application of the switching regression model to allocate workers into the primary and secondary labor markets is considered to be the best solution to the classification problem of the empirical testing of the dual labor market theory. In such models, normality of the error terms is assumed. This paper adopts the switching regression model to test the dual labor market theory by assuming different distributions of the error terms. The test results strongly support the dual labor market theory regardless of the assumption one makes about the error terms. However, the results indicate that different distribution can lead to different percentage distributions of workers in the two segments. In particular, the normal distribution generates more workers in the primary segment than the non-normal distributions. Therefore, care must be taken not to generalize the type of industries or occupations that fall under the primary and secondary segments.

论我国劳动力市场分割

我国劳动力市场处于一种多元分割状态,城乡之间、城市内部、农村内部都没有统一的劳动力市场,城市内有头等和次等劳动力市场,农村中有农业和非农业劳动力市场,其中尤以城乡分割最为严格.在二元结构下.以户籍管理制度为基础的一系列正式制度安排,使劳动力市场分割有了制度基础,它非正式制度相呼应,形成了我国劳动力市场分割的特殊形态.本文从综合角度研究了我国劳动力市场分割现状并对其原因进行了探讨.

How urbanization affect employment and social interactions

We develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties. We show that, in denser areas, individuals choose to interact with more people and meet more random encounters (weak ties) than in sparsely populated areas. We also demonstrate that, for a low urbanization level, there is a unique steady-state equilibrium where workers do not interact with weak ties, while, for a high level of urbanization, there is a unique steady-state equilibrium with full social interactions. We show that these equilibria are usually not socially efficient when the urban population has an intermediate size because there are too few social interactions compared to the social optimum. Finally, even when social interactions are optimal, we show that there is over-urbanization in equilibrium.     

Multi-dimensional risk and the cost of business cycles

This paper analyzes the welfare costs of business cycles when workers face uninsurable idiosyncratic labor income risk. In accordance with the previous literature, this paper decomposes labor income risk into an aggregate and an idiosyncratic component, but in contrast to the previous literature, this paper allows for multiple sources of idiosyncratic labor income risk. Using the multi-dimensional approach to idiosyncratic risk, this paper provides a general characterization of the welfare cost of business cycles when preferences and the (marginal) process of individual labor income in the economy with business cycles are given. The general analysis shows that the introduction of multiple sources of idiosyncratic risk never decreases the cost of business cycles, and strictly increases it if there are cyclical fluctuations across the different sources of risk. This paper also provides a quantitative analysis based on a version of the model that is calibrated to match US labor market data. The quantitative analysis suggests that realistic variations across two particular dimensions of idiosyncratic labor income risk increase the welfare cost of business cycles by a substantial amount.
