    College Quality and the Wages of Young Men

    Using the rich data from the National Longitudinal Survey of Youth, we show that several dimensions of college quality have substantial positive impacts on young men’s wages. This finding is robust to a wide array of alternative specifications. Controlling for ability reveals that sorting of more able persons into better colleges accounts for only a modest portion of the unconditional quality effect. We find that young black men reap larger gains to quality than do young white men. Our results also indicate that attending a college with a racially diverse student body increases the later earnings of both white and black men

    Galectin-3 regulates intracellular trafficking of EGFR through Alix and promotes keratinocyte migration.

    The EGFR-mediated signaling pathways are important in a variety of cellular processes, including cell migration and wound re-epithelialization. Intracellular trafficking of EGFR is critical for maintaining EGFR surface expression. Galectin-3, a member of an animal lectin family, has been implicated in a number of physiological and pathological processes. Through studies of galectin-3-deficient mice and cells isolated from these mice, we demonstrated that the absence of galectin-3 impairs keratinocyte migration and skin wound re-epithelialization. We have linked this pro-migratory function to a crucial role of cytosolic galectin-3 in controlling intracellular trafficking and cell surface expression of EGFR after EGF stimulation. Without galectin-3, the surface levels of EGFR are markedly reduced, and the receptor accumulates diffusely in the cytoplasm. This is associated with reduced rates of both endocytosis and recycling of the receptor. We have provided evidence that this previously unreported function of galectin-3 may be mediated through interaction with its binding partner Alix, which is a protein component of the ESCRT (endosomal sorting complex required for transport) machinery. Our results suggest that galectin-3 is potentially a critical regulator of a number of important cellular responses through its intracellular control of trafficking of cell surface receptors

    Productivity, Wages, and Marriage: The Case of Major League Baseball

    The effect of marriage on productivity and, consequently, wages has been long debated in economics. A primary explanation for the impact of marriage on wages has been through its impact on productivity, however, there has been no direct evidence for this. In this paper, we aim to fill this gap by directly measuring the impact of marriage on productivity using a sample of professional baseball players from 1871 - 2007. Our results show that only lower ability men see an increase in productivity, though this result is sensitive to the empirical specification and weakly significant. In addition, despite the lack of any effect on productivity, high ability married players earn roughly 16 - 20 percent more than their single counterparts. We discuss possible reasons why employers may favor married men

    College Quality and Wages in the United States

    Abstract We estimate the effects of the quality of the college a student attends on their later earnings using data from a cohort of U.S. college students from the late 1970s and early 1980s. We rely on a linear selection on observables identification strategy, which is justified in our context by a very rich set of conditioning variables. We find economically important earnings effects of college quality for men and women, as well as effects on educational attainment, spousal earnings and other demographic variables. These effects remain roughly constant over time and result primarily from effects on wages, rather than from effects on hours or labor force participation. We find that, over the lower part of the range of college quality, increases in college quality (which entail higher expenditures per student) pass a simple social cost-benefit test

    Term Limits and Electoral Competitiveness: California\u27s State Legislative Races

    Get PDF
    California’s legislative term limits have dramatically reduced campaign expenditures. Real expenditures during the three general elections after the term limits initiative passed in 1990 were lower than in even 1976. This drop has occurred at the same time that races have become closer contests and more candidates are running for office. By any measure, term limits have coincided with large changes in the level of political competition, even before term limits have forcibly removed a single politician from office. The changes are so large that more incumbents are being defeated, races are closer, more candidates are running, and fewer single candidate races than occur at any other time during our sample period from 1976 to 1994
