Marriage,cohabitation and women's response to changes in the male wage structure

Using microdata and grouped data that cover the period 1996 to 2006, we assess the extent to which cohabiting women adjust their labour supply to a lesser extent, if any, than married women in response to changes in male wages. Both microdata regressions and grouping estimators unambiguously indicate that cohabiting women respond less to variation in male wages than married women. However, the magnitude of the difference is not sizeable. We also assess the magnitude of married men's and cohabiting men's own wage elasticities and find that they do not differ much. Combined with the fact that male earnings account for roughly two-thirds of family earnings, these two findings explain why the impact of changes in male wages on family earnings is very similar for married couples and cohabiting couples: in both cases, a 10% decline in male wages appears to induce roughly a 6% drop in family earnings.     

Genetics, family structure, and economic growth

Recent biomedical research shows that roughly three-quarters of cognitive abilities are attributable to genetics and family environment. This paper presents a growth model that characterizes the role of the intergenerational transmission of genes and the effect of family environment on growth trajectories. If the average human or physical capital stocks are sufficiently low, the model shows that the economy will be caught in a poverty trap. Conversely, countries with more resources will converge to a bala nced growth path where the average rate of genetic transmission of skills from parents to children determines the long-run rate of output growth. Increased genetic diversity (or income inequality) is shown to raise the fertility rate and reduce output growth in the transitional dynamics. Thus, nature and nurture are able to explain a variety of countries' growth experiences.     

Birth order,family size,and achievement: family structure and wage determination

The influence of birth order and childhood family size on future achievement is discussed. Two major empirical findings are presented by the author. "First, neither birth order nor childhood family size significantly influences the level or growth rate of wages, a result that is consistent with previous research. Second, family size is both a statistically and economically significant determinant of women's employment status: women from small families work less than women from large families when they are young and more than women from large families when they are more mature." The geographical focus is on the United States.     

The labor market and corporate structure

We analyze the impact of labor demand and labor market regulations on the corporate structure of firms. Higher wages are associated with lower monitoring, irrespective of whether these high wages are caused by labor market regulations, unions or higher labor demand. We also find that the organization of firms has important macroeconomic implications. In particular, monitoring is a type of “rent-seeking” activity and the decentralized equilibrium spends excessive resources on monitoring. Labor market regulations that reduce monitoring by pushing wages up may increase net output or reduce it only by a small amount even though they reduce employment.     

Globalization,labor standards,and women's rights: dilemmas of collective (in)action in an interdependent world

This paper challenges the idea that a “social clause” to enforce global labor standards through international trade agreements serves the interests of women export workers in poor countries. Drawing on fieldwork in Bangladesh and empirical studies, the author argues that exploitative as these jobs appear to Western reformers, for many women workers in the South they represent genuine opportunities. Clearly, these women would wish to better their working conditions; yet having no social safety net, and knowing that jobs in the informal economy, their only alternative, offer far worse prospects, women cannot fight for better conditions. Moreover, global efforts to enforce labor standards through trade sanctions may lead to declining employment or to the transfer of jobs to the informal economy. Lacking measures that also address the conditions of workers in this informal economy, demands for “the social clause” will reinforce, and may exacerbate, social inequalities in the labor market.     

Changes in the wage structure,family income,and children's education

We exploit the changes in the distribution of family income to estimate the effect of parental resources on college education. Our strategy exploits the fact that families at the bottom of the income distribution were much poorer in the 1990s than they were in the 1970s, while the opposite is true for families in the top quartile of the distribution.  Our estimates suggest large effects of family income on enrollments.  For example, we find that a 10 percent increase in family income is associated with a 1.4 percent increase in the probability of attending a four-year college.     

Fertility,household structure,and parental labor supply: Evidence from China

This study examines the effects of fertility on household structure and parental labor supply in China. To solve the endogeneity problem, we use a unique survey on households with twin children and a comparison group of non-twin households. The ordinary least squares estimates show a negative correlation between fertility and parental labor supply in rural China. Using twinning as a natural experiment, we do not find evidence on the negative effects of fertility on parental labor supply. By contrast, we find that the twinning-induced increase in fertility significantly enhances the coresidence of grandparents in rural China. We suggest that the negative effects of fertility on parental labor supply are mitigated by the childcare provided by grandparents in rural China. We also find that fertility does not induce coresidence of grandparents in urban China. Our results have important implications for population and public childcare policies.     

Married women's labor supply and economic development: Evidence from Sri Lankan household data

Women's labor supply in Sri Lanka has increased steadily since the early 1990s following economic reforms, but remains well below the level predicted by national income, a feature shared by a number of Asian and Latin American countries that have undergone similar reforms and economic growth. To understand the microeconomic determinants of women's work in Sri Lanka's growing economy, this paper estimates a binary‐choice model of married women's labor supply using household survey data spanning a 23‐year period. Decomposition and cohort analysis reveal that women have been drawn into the workforce through falling fertility rates, rising tertiary education, and declining income effects among younger generations, but other factors have undermined this positive trend. Educational attainment reduces married women's labor supply except at the tertiary level, consistent with social stigmas associated with married women in non‐white‐collar employment. The strict sectoral segregation of married women by education level supports this hypothesis. In addition, growth has been concentrated in low‐skilled sectors with self‐employment more prevalent, reducing employment prospects of educated women and prompting their labor force withdrawal. This suggests it is the structure of economic development, rather than speed, that matters for women's labor force activity.     

Skilled labor, unskilled labor, and economic growth

We study a growth model in which workers with different skill levels are imperfect substitutes. We show that economies with high substitutability between skilled and unskilled workers have high levels of capital, output, and a high proportion of skilled workers.     

Heterogeneous labor skills,the median voter and labor taxes

This paper analyzes the median voter?s most preferred sequences of labor taxes in the standard neoclassical growth model. We consider an infinite horizon economy in which agents are heterogeneous with respect to both initial wealth and labor skills. We start by providing a set of sufficient conditions for the existence of a Condorcet winner. We then characterize the most preferred tax sequence by the median agent. First, we show that marginal labor taxes depend directly on the absolute value of the distance between the median and the mean value of the skills? distribution. Second, we find that in contrast to the intuition stemming from standard representative agent economies, labor taxes are more volatile and counter-cyclical taxation (e.g., increasing taxes in recession) might be optimal depending on the correlation between inequality and TFP. To assess the quantitative relevance of these findings, we calibrate the model economy to six countries and find that counter-cyclical labor taxation is optimal for all but the US.

Social network structure,segregation, and equality in a labor market with referral hiring

We examine the effects of social network structure on inequality in a model of referral hiring that focuses on groups rather than individuals. More random social networks yield higher employment rates than less random ones if the population is integrated or job vacancy information flows are random. However less random social networks allow for better containment of job information inside a group in a segregated population with non-random job information flows, resulting in higher employment rates. We report on the robustness of these findings with respect to the size of minority and majority groups and the amount of social segregation.     

The career and family choices of women: A dynamic analysis of labor force participation,schooling, marriage,and fertility decisions

This paper formulates and estimates a discrete time, discrete choice dynamic labor supply model in which marriage, fertility, and education are choice variables. The dynamics of these choices are captured by various forms of state and duration dependence. Uncertainty comes from the imperfect control women have over births and from a choice-specific random shock to utility each period. Women choose different career and family life-cycle paths because of these uncertainties and also because they have different tastes. The structural parameters of the model are estimated using maximum likelihood estimation techniques with data from the National Longitudinal Survey of Youth.     

The relations among child quality,family structure,and the value of the mother's time in Malaysia

A model of the determinants of child quality and of the value of a woman's time is developed and tested using data from the Malaysian Family Life Survey of 1976-1977. Child quality is measured by educational attainment; factors influencing the value of the mother's time include size and age composition of household, family income, education, and hours worked. The results indicate that size and age composition of household affect a woman's asking wage. However, more data are needed before the effects of family structure on schooling can be measured with confidence.     

Perpetual growth,the labor share,and robots

ABSTRACT

The recent literature on the economic effects of machine learning, robotization and artificial intelligence suggests that there may be an upcoming wave of substitution of human labor by machines. We argue that these new technologies may lead to so-called perpetual growth, i.e. growth of per capita income with a non-progressing state of technology. We specify an exact parameter threshold beyond which perpetual growth emerges, and argue that ongoing technological change may bring the threshold in reach. We also show that in a state of perpetual growth, factor-eliminating technological progress reduces the role of labor in the production process and that this leads to a rising wage rate but ever-declining share of wage income. We present simulation experiments on several policy options to combat this inequality, including a universal basic income as well as an option in which workers become owners of ‘robots’.     

Culture,legal heritage and the regulation of labor

According to cross-cultural psychologists, cross-country differences in individualism vs. collectivism constitute an important dimension of cultural variation. Legal-economic theorists argue that legal philosophies such as common law and civil law have developed differently over centuries and have persistent effects. In this paper, we argue that the effects of culture and institutions should not be analyzed in isolation from each other, as this disregards their interactions. We merge the two separate literatures on cultural attributes and legal origin theories, and derive a hypothesis regarding their joint effects on labor market regulations. We hypothesize that the effect of individualism on the political determination of labor regulations should be particularly pronounced in more market-oriented economic systems (as in British common law countries) compared to more rigid and bureaucratic state-centered systems (as in French civil law countries). Market oriented economies give individual effort and ability greater room to flourish, which in individualistic cultures yields weaker labor regulations. The effect of individualism should be smaller in state centered systems. Using data on the average rigidity of labor regulations during the years 1950–2004 in 86 countries, we find that the negative effect of individualism on the rigidity of labor regulations is enhanced by the presence of a common law legal system. In fact, individualism has no effect on the rigidity of labor market regulations in civil law countries. Analogously, the negative effect of common law legal origin on labor market regulations is found to be conditional on the level of individualism. Individualism and common law legal systems are complements in the determination of labor regulations.     

Taxation,insurance, and precautionary labor

We examine optimal taxation and social insurance with adverse selection in competitive insurance markets. In a previous literature, it has been shown that, with perfect insurance markets, social insurance improves welfare since it is able to redistribute without creating distortions. This result has been taken as robust to the introduction of adverse selection as this would only provide additional justifications for social insurance. We show, however, that adverse selection can weaken the case for social insurance compared to a situation with perfect markets. Whenever social insurance mitigates private underinsurance, it also causes welfare-reducing effects by decreasing precautionary labor supply and hence tax revenue. In addition, adverse selection may reduce the redistributive potential of social insurance. We illustrate our general results using different equilibrium concepts for the insurance market. Notably, we derive conditions under which a complete renunciation of social insurance is optimal and the government only relies on income taxation to achieve its redistributive objectives.
