The labor supply of married women: why does it differ across U.S. cities?

Using Census Public Use Micro Sample (PUMS) data for 1980, 1990 and 2000, this paper documents a little-noticed feature of U.S. labor markets that there is wide variation in the labor market participation rates and annual work hours of white married women across urban areas. This variation is also large among sub-groups, including women with children and those with different levels of education. Among the explanations for this variation one emerges as particularly important: married women's labor force participation decisions appear to be very responsive to commuting times. There is a strong empirical evidence demonstrating that labor force participation rates of married women are negatively correlated with commuting time. What is more, the analysis shows that metropolitan areas which experienced relatively large increases in average commuting time between 1980 and 2000 also had slower growth of labor force participation of married women. This feature of local labor markets may have important implications for policy and for further research.Women - Employment ; Labor market

Local price variation and labor supply behavior

In standard economic theory, labor supply decisions depend on the complete set of prices: the wage and the prices of relevant consumption goods. Nonetheless, most of theoretical and empirical work ignores prices other than wages when studying labor supply. The question we address in this paper is whether the common practice of ignoring local price variation in labor supply studies is as innocuous as has generally been assumed. We describe a simple model to demonstrate that the effects of wage and non-labor income on labor supply will typically differ by location. We show, in particular, the derivative of the labor supply with respect to non-labor income will be independent of price only when labor supply takes a form based on an implausible separability condition. Empirical evidence demonstrates that the effect of price on labor supply is not a simple "up-or down shift" that would be required to meet the separability condition in our key proposition.Labor supply ; Price levels

Earnings functions when wages and prices vary by location

In this paper we study whether location-specific price variation likely affects statistical inference and theoretical interpretation in the empirical implementation of human capital earnings functions. We demonstrate, in a model of local labor markets, that the ?return to schooling" is a constant across locations if and only if preferences are homothetic ? a special case that seems unlikely to generally pertain. Examination of U.S. Census data (for 1980, 1990, and 2000) provides persuasive evidence that the return to a college education, relative to a high school education, does indeed vary widely across cities, e.g., in 1990 the return in Houston is 0.54 while in Seattle it is only 0.33. We provide theoretical reasons to suspect that the returns to education are relatively lower in expensive high-amenity locations, and present evidence consistent with this prediction. Finally, we raise concerns about standard empirical exercises in labor economics which treat the returns to education as a single parameter.Wages ; Labor market ; Education

African-American economic progress in urban areas: a tale of 14 American cities

How significant was the economic progress of African-Americans in the U.S. between 1970 and 2000? In this paper we examine this issue for black men 25-55 years old who live in 14 large U.S. metropolitan areas. We present the evidence that significant racial disparities remain in education and labor market outcomes of black and white men. We discuss changes in industrial composition, migration, and demographic changes that might have contributed to the stagnation of economic progress of black men between 1970 and 2000. In addition, we show that there was no progress in a financial well-being of black children, relative to white children, between 1970 and 2000.African Americans - Economic conditions

The role of location in evaluating racial wage disparity

A standard object of empirical analysis in labor economics is a modified Mincer wage function in which an individual's log wage is specified to be a function of education, experience, and an indicator variable identifying race. Researchers hope that estimates from this exercise can be informative about the impact of minority status on labor market success. Here we set out a theoretical justification for this regression in a context in which individuals live and work in different locations. Our model leads to the traditional approach, but with the important caveat that the regression should include location-specific fixed effects. Given this insight, we reevaluate evidence about the black-white wage disparity in the United States.Income distribution ; Wages ; Discrimination in employment

Are children 'normal'?

In his classic work on the economics of fertility, Becker (1960) suggests that children are likely “normal.” We examine this contention. Our first step is documenting an empirical regularity about the cross section of white married couples in the U.S.: when we restrict comparisons to households living in broadly similar locations (e.g., in expensive urban areas, or in rural areas), completed fertility is positively correlated with the husband’s income. Two alternative models rationalize the data—one in which children are “normal” and a second in which the observed pattern emerges solely as a consequence of rational sorting by households. In an effort to sort out causal effects, we undertake a rather specialized empirical exercise to analyze the localized impact on fertility of the mid-1970s increase in world energy prices—an exogenous shock that substantially increased men’s incomes in the Appalachian coal-mining region. We find that children are indeed “normal.”Demography

Are Children "Normal"?

We examine Becker's (1960) contention that children are "normal." For the cross section of non-Hispanic white married couples in the U.S., we show that when we restrict comparisons to similarly-educated women living in similarly-expensive locations, completed fertility is positively correlated with the husband's income. The empirical evidence is consistent with children being "normal." In an effort to show causal effects, we analyze the localized impact on fertility of the mid-1970s increase in world energy prices – an exogenous shock that substantially increased men's incomes in the Appalachian coal-mining region. Empirical evidence for that population indicates that fertility increases in men's income.economics of fertility, location choice, Appalachian fertility
