Does employment protection help immigrants? Evidence from European labor markets

High levels of employment protection reduce hiring and firing and have a theoretically ambiguous effect on the employment level. Immigrants, being new to the labor market, may be less aware of employment protection regulations and less likely to claim their rights, which may create a gap between the costs for employers of hiring a native relative to hiring an immigrant. This paper tests that hypothesis drawing on evidence for the EU and on two natural experiments for Spain and Italy. The results suggest that strict employment protection legislation (EPL) gives immigrants a comparative advantage relative to natives. Stricter EPL is found to reduce employment and reduce hiring and firing rates for natives. By contrast, stricter EPL has a much smaller effect on immigrants.     

With a little help from abroad: The effect of low-skilled immigration on the female labour supply

We examine whether and how the inflow of female immigrants who specialize in household production affects the labour supply of Italian women. To identify the causal effect, we exploit the family reunification motives and network effects (i.e., the tendency of newly arriving female immigrants to settle in places where males of the same country already live) which is used as an instrument for the geographical distribution of female foreign workers. We find that when the number of immigrants who provide household services is higher, native Italian women spend more time at work (intensive margin) without affecting their labour force participation (extensive margin). This impact is concentrated on highly skilled women whose time has a higher opportunity cost. These results also hold after a battery of robustness checks. We present some further evidence that is also consistent with the idea that the impact works through substitution in household work rather than complementarities in the production sector. Finally, we show that immigration arises as a substitute to publicly provided welfare services, although this phenomenon raises concerns regarding the fairness and sustainability of this private and informal welfare model.     

The elasticity of derived demand, factor substitution, and product demand: Corrections to Hicks' formula and Marshall's Four Rules

The concept of the elasticity of substitution between capital and labor, introduced by John Hicks and Joan Robinson over 75 years ago, has had important implications in labor economics and several areas of economic inquiry. In his The Theory of Wages (1932/1963), Hicks developed a formula that has proven very useful in relating the substitution elasticity to the derived demand for productive factors, the distribution of factor incomes, and Marshall's Four Rules. This short paper shows that the original and subsequent derivations of Hicks' celebrated formula contained a slip (that factor shares are independent of the substitution elasticity and therefore constant), presents a new derivation and a corrected formula, and demonstrates that, with the corrected formula, Marshall's First Rule based on the substitution elasticity is no longer generally valid.     

Generalized method of moments (GMM) based inference with stratified samples when the aggregate shares are known

We show how to do efficient moment based inference using the generalized method of moments (GMM) when data is collected by stratified sampling and the maintained assumption is that the aggregate shares are known.     

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.     

New results on the effect of maternal work hours on children's overweight status: Does the quality of child care matter?

Existing empirical research on child overweight derives mainly from North America and points at rising maternal employment as an explanation for the increasing trend in child weight. These results cannot be replicated in Denmark, where an increase in maternal work hours does not increase the likelihood of weight problems for their children. This paper tests four possible explanations for this difference: (1) the effect of maternal employment on child obesity is heterogeneous and varies according to the country's weight distribution; (2) the quality of child care is on average higher in Denmark; (3) the counterfactual care provided by Danish mothers is of lower quality; and (4) Danish fathers contribute significantly to their children's health. This paper finds evidence consistent with the hypotheses that Danish child care and fathers play a significant role in explaining the absence of a significant relationship between maternal work hours and children's overweight status.     

Job satisfaction and gender: Why are women so happy at work?

By most objective standards, women's jobs are worse than men's, yet women report higher levels of job satisfaction than do men. This paper uses a recent large-scale British survey to document the extent of this gender differential for eight measures of job satisfaction and to evaluate the proposition that identical men and women in identical jobs should be equally satisfied. Neither the different jobs that men and women do, their different work values, nor sample selection account for the gender satisfaction differential. The paper's proposed explanation appeals to the notion of relative well-being, especially relative to workers' expectations. An identical man and woman with the same jobs and expectations would indeed report identical job satisfaction, but women's expectations are argued to be lower than men's. This hypothesis is supported by the finding that the gender satisfaction differential disappears for the young, the higher-educated, professionals and those in male-dominated workplaces, for all of whom there is less likely to be a gender difference in job expectations.     

Brain drain and institutions of governance: Educational attainment of immigrants to the US 1988–1998

We investigate the impact of home country institutions on the skill level of immigrants to the United States over 1988–1998. Specifically, we explore the hypothesis that institutions are multidimensional and that the different dimensions have conflicting impacts on the migration of skilled labor. Using an exploratory factor analysis on fifteen institutional variables, we identify the following dimensions of institutional character: credibility, transparency, democracy, and the security of civil society. We find that credibility and transparency increase the magnitude of brain drain, security reduces it, and democracy has no significant impact.     

Social Security and elderly labor supply: Evidence from the Health and Retirement Study

This study uses panel data from the Health and Retirement Study (HRS) to estimate the effects of Social Security income on elderly labor supply in the 1990s and early 2000s. The identification strategy takes advantage of the 1977 amendments to the Social Security Act, which led to a large, unanticipated reduction in Social Security benefits for those born after January 1, 1917. Despite the advanced age of the notch cohorts, there is a significant, negative and surprisingly elastic relationship between Social Security income and hours of work. This suggests that currently proposed reductions in benefits would induce Social Security recipients to work more hours in retirement, even through their 70s and early 80s.     

Bargaining and strikes: Towards an evolutionary framework

Conventional models of strikes start with the assumption that the bargainers' uniquely rational beliefs can be worked out in advance. Strikes are then explained as either the result of institutional constraints or of the possibility of irrationality. By contrast the evolutionary approach begins with a recognition that bargaining is naturally indeterminate and that, in the absence of a unique model of rational bargaining, conflict-free agreements between rational trades unions and firms reflect the evolution of one out of many possible conventions. This paper explores the alternative interpretation of strikes afforded by this perspective. In particular, it shows how strikes help shape the dispositions of bargainers (as opposed to just revealing it), how periods of conflict are succeeded by periods of industrial peace (and vice versa), and how the stability of bargaining protocols depends not only on the conventions regulating the relations between unions and firms but also on those between workers and union leaders as well as on technological innovations.     

Metonymy and cross-section demand

Cross-section consumer expenditure data are frequently used to draw conclusions about consumer demand behavior. Such conclusions, however, are justified only under certain assumptions, which are often left unstated in the empirical demand literature. An assumption of this type, the metonymy hypothesis, was stated rigorously and exploited by Härdle et al. when analyzing the monotonicity of aggregate demand functions. The purpose of the present paper is to examine the metonymy hypothesis in more detail. We prove that the distribution of demand vectors derived from a not necessarily metonymic population is identical with the distribution derived from some metonymic population. This implies, in particular, that the metonymy hypothesis cannot be rejected or confirmed on the basis of data from a single cross-section.     

S-curve dynamics of trade between Sweden and her trading partners

The S-curve sums up the dynamic relationship between terms of trade and trade balance. This pattern has received weak support in some developed and less developed countries when aggregate trade data are used. Empirical regularities based on aggregate trade data can be biased since aggregation can potentially suppress some of the patterns observed in trade at the bilateral level. This paper overcomes this problem by employing bilateral trade data from Sweden and finds that the S-curve is invariant to this level of disaggregation. Indeed, Sweden has a bilateral S-curve with 12 out of 17 cases examined for the 1980Q1–2005Q1 period.     

Curbing cream-skimming: Evidence on enrolment incentives

Using data from a large, U.S. federal job training program, we investigate whether enrolment incentives that exogenously vary the ‘shadow prices’ for serving different demographic subgroups of clients influence case workers' intake decisions. We show that case workers enroll more clients from subgroups whose shadow prices increase but select at the margin weaker-performing members from those subgroups. We conclude that enrolment incentives curb cream-skimming across subgroups leaving a residual potential for cream-skimming within a subgroup.     

A bootstrap algorithm for testing cointegration rank in VAR models in the presence of stationary variables

In this paper, a bootstrap algorithm for a reduced rank vector autoregressive (VAR) model which also includes stationary regressors, is analyzed. It is shown that the bootstrap distribution for estimating the rank converges to the distribution derived from the usual asymptotic framework. Because the asymptotic distribution will typically depend on unknown parameters, bootstrap distributions are of considerable interest in this context. The result of an application and some Monte Carlo experiments are also presented.     

International foreign exchange agreements and nominal exchange rate volatility: a GARCH application

For eight major national currencies, this study estimates, and tests several hypotheses with, a t-distribution GARCH model of daily spot nominal exchange rate changes. The sample period covered is June 1, 1982 through September 30, 1992. By using likelihood ratio and parameter stability tests, it finds that for most of the currencies considered, both the conditional means and variances of unexpected exchange rate changes experienced statistically significant structural breaks across the five subperiods that are associated with four episodes of international foreign-exchange policy coordination. The study also finds that the orderings of the GARCH-estimated unconditional standard deviations roughly match the orderings of the sample standard deviations across the five subperiods. An explanation is provided for what underlying factors contributed to these structural shifts.     

Industry trade between Canada and Mexico: Will a weakening peso help Mexican manufacturing in the long run?

Mexico has longed served as one of Canada's major trade partner, but the plunging peso has had drastic effects across North America. This study investigates the bilateral trade relationship between Canada and Mexico for 27 individual industries, from 1973 to 2006. Cointegration analysis shows that overall sensitivity to the real exchange rate is weak, but that the trade balances of certain manufacturing industries do indeed improve after a currency depreciation. The “J-curve” effect is present for certain electrical and mechanical industries, suggesting that the recent decline of the peso may currently be having a negative impact on Mexican trade—but that it might eventually be beneficial, particularly for the Machinery and Transport Equipment sector.
