    Cleaning Up - How Hospital Outsourcing Is Hurting Workers and Endangering Patients
    Zuberi, Dan. 2013. Cleaning Up - How Hospital Outsourcing Is Hurting Workers and Endangering Patients. Abstract

    To cut costs and maximize profits, hospitals in the United States and many other countries are outsourcing such tasks as cleaning and food preparation to private contractors. In, the first book to examine this transformation in the healthcare industry, Dan Zuberi looks at the consequences of outsourcing from two perspectives: its impact on patient safety and its role in increasing socioeconomic inequality. Drawing on years of field research in Vancouver, Canada as well as data from hospitals in the U.S. and Europe, he argues that outsourcing has been disastrous for the cleanliness of hospitals-leading to an increased risk of hospital-acquired infections, a leading cause of severe illness and death-as well as for the effective delivery of other hospital services and the workers themselves.

    Feigenbaum, James J, and Cameron A Shelton. 2013. “The Vicious Cycle: Fundraising and Perceived Viability in US Presidential Primaries.” Quarterly Journal of Political Science 8 (1): 1-40. Publisher's Version Abstract
    Scholars of presidential primaries have long posited a dynamic positive feedback loop between fundraising and electoral success. Yet existing work on both directions of this feedback remains inconclusive and is often explicitly cross-sectional, ignoring the dynamic aspect of the hypothesis. Pairing high-frequency FEC data on contributions and expenditures with Iowa Electronic Markets data on perceived probability of victory, we examine the bidirectional feedback between contributions and viability. We find robust, significant positive feedback in both directions. This might suggest multiple equilibria: a candidate initially anointed as the front-runner able to sustain such status solely by the fundraising advantage conferred despite possessing no advantage in quality. However, simulations suggest the feedback loop cannot, by itself, sustain advantage. Given the observed durability of front-runners, it would thus seem there is either some other feedback at work and/or the process by which the initial front-runner is identified is informative of candidate quality.

    Using Eurobarometer data, we document large variation across European countries in education gradients in income, self-reported health, life satisfaction, obesity, smoking and drinking. While this variation has been documented previously, the reasons why the effect of education on income, health and health behaviors varies is not well understood. We build on previous literature documenting that cohorts graduating in bad times have lower wages and poorer health for many years after graduation, compared to those graduating in good times. We investigate whether more educated individuals suffer smaller income and health losses as a result of poor labor market conditions upon labor market entry. We confirm that a higher unemployment rate at graduation is associated with lower income, lower life satisfaction, greater obesity, more smoking and drinking later in life. Further, education plays a protective role for these outcomes, especially when unemployment rates are high: the losses associated with poor labor market outcomes are substantially lower for more educated individuals. Variation in unemployment rates upon graduation can potentially explain a large fraction of the variance in gradients across different countries.

    In this paper, we build on the literature that examines associations between height and health outcomes of the elderly. We investigate the associations of height shrinkage at older ages with socioeconomic status, finding that height shrinkage for both men and women is negatively associated with better schooling, current urban residence, and household per capita expenditures. We then investigate the relationships between pre-shrinkage height, height shrinkage, and a rich set of health outcomes of older respondents, finding that height shrinkage is positively associated with poor health outcomes across a variety of outcomes, being especially strong for cognition outcomes.

    Huang, Wei, and Yi Zhou. 2013. “Effects of Education on Cognition at Older Ages: Evidence from China’s Great Famine.” Social Science & Medicine 98: 54-62. Publisher's Version Abstract

    This paper explores whether educational attainment has a cognitive reserve capacity in elder life. Using pilot data from the China Health and Retirement Longitudinal Study (CHARLS), we examined the impact of education on cognitive abilities at old ages. OLS results showed that respondents who completed primary school obtained 18.2 percent higher scores on cognitive tests than those who did not. We then constructed an instrumental variable (IV) by leveraging China’s Great Famine of 1959e1961 as a natural experiment to estimate the causal effect of education on cognition. Two-stage least squares (2SLS) results provided sound evidence that completing primary school significantly increases cognition scores, especially in episode memory, by almost 20 percent on average. Moreover, Regression Discontinuity (RD) analysis provides further evidence for the causal interpretation, and shows that the effects are different for the different measures of cognition we explored. Our results also show that the Great Famine can result in long-term health consequences through the pathway of losing educational opportunities other than through the pathway of nutrition deprivation.

    Huang, Wei. 2015. “Do ABCs Get More Citations Than XYZs?” Economic Inquiry 53: 773-789. Publisher's Version Abstract

    Using a sample of US-based scientific journal articles, I examine the relationship between author surname initials and paper citations, finding that the papers with first authors whose surname initials appear earlier in the alphabet get more citations, and that this effect does not exist for non-first authors. Further analysis shows that the alphabetical order effect is stronger in those fields with longer reference lists, and that such alphabetical bias exists among citations by others and not for self-citations. In addition, estimates also reveal that the alphabetical order effect is stronger when the length of reference lists in citing papers is longer. These findings suggest that the order in reference lists plays an important role in the alphabetical bias.

    Collaborating with People Like Me: Ethnic Co-authorship within the US
    Freeman, Richard B., and Wei Huang. 2015. “Collaborating with People Like Me: Ethnic Co-authorship within the US.” Journal of Labor Economics 33 (S1): S289-S318. Abstract

    By examining the ethnic identity of authors in over 2.5 million scientific papers written by US-based authors from 1985 to 2008, we find that persons of similar ethnicity coauthor together more frequently than predicted by their proportion among authors. The greater homophily is associated with publication in lower-impact journals and with fewer citations. Meanwhile, papers with authors in more locations and with longer reference lists get published in higher-impact journals and receive more citations. These findings suggest that diversity in inputs by author ethnicity, location, and references leads to greater contributions to science as measured by impact factors and citations.

    Aghion, Philippe, and Alexandra Roulet. 2014. “Growth and the Smart State.” Annual Review of Economics 6: 913-926. Publisher's Version Abstract
    As countries develop, the main driver of economic growth shifts from imitation to innovation. These two sources of growth require different policies and institutions. In particular, in this article we argue that the transition from an imitation-based to an innovation-based economy calls the old welfare state model into question. It is not so much the size of the state that is at stake but rather its governance. What we need to foster economic growth in developed economies is not a reduced state but a strategic state, which acts as a catalyst using selective and properly governed support to the market-driven innovation process. This idea of a strategic state that targets its investments to maximize growth in the face of hard budget constraints departs both from the Keynesian view of a state sustaining growth through demand-driven policies and from the neoliberal view of a minimal state confined to its regalian functions.
