DOES THE WOMEN,INFANTS, AND CHILDREN PROGRAM IMPROVE INFANT HEALTH OUTCOMES?

We reevaluate the causal impacts of prenatal participation in the Women, Infants, and Children (WIC) supplemental nutrition program on birth outcomes by simultaneously accounting for self-selection into WIC and systematic underreporting of program participation. Combining survey data from the Early Childhood Longitudinal Study-Birth Cohort with administrative data from the USDA, we extend partial identification methods to reflect institutional details of the WIC program and validate WIC program participation for a mixture of positive and negative responses. Our preferred estimates imply that WIC increases the prevalence of normal birth weight by at least 4.8% and normal gestation duration by at least 3.7%. (JEL C14, C21, I12, I31, I38)     

WHAT DO UNIONS DO TO PENSION PERFORMANCE?

Unions can have either positive or negative effects on risk‐adjusted returns in pension plans. On the positive side, a union can improve monitoring of pension advisors and asset managers. On the negative side, the union may sacrifice returns by making investments that promote union goals. This paper discusses how the structure of the pension plan affects the union's ability and willingness to sacrifice returns to promote union goals. Using panel data on over 38,000 pension plans drawn from IRS Form 5500 filings between 1988 and 2008, we find the lowest performing plans are unionized multi‐employer plans. Among defined contribution plans, the underperformance of multi‐employer union plans disappears when the pension is controlled by individual participants. (JEL J32, J51)     

DOES RAIDING EXPLAIN THE NEGATIVE RETURNS TO FACULTY SENIORITY?

We track faculty for 30 yr at five PhD‐granting departments of economics. Two‐thirds of faculty who take alternative employment move downward; less than one‐quarter moves upward. We find a substantial penalty for seniority, even after richly controlling for faculty productivity, and the penalty is little changed when we allow wages and returns to seniority to differ by mobility status. Faculty who end up moving to better or comparable positions were penalized as severely for seniority while they were in our sample as faculty who stay. These results are incompatible with the raiding hypothesis. Faculty from top 10 programs are also punished for seniority but to a lesser degree than other faculty, which could reflect reduced monopsony power against such faculty if they are more marketable. All results persist when we control for prospective publications and allow lower returns for older publications. Match‐quality bias has dissipated in the post‐internet period, which may be the consequence of greater availability of information. (JEL J62, J44, J42)     

GETTING INTO THE WEEDS: DOES LEGAL MARIJUANA ACCESS BLUNT ACADEMIC PERFORMANCE IN COLLEGE?

This paper examines the effect of legal access to marijuana on student performance stemming from a voter-approved initiative legalizing marijuana for those 21 and older in the State of Washington. Using panel data from a medium-sized public university, we use a within-student and within-class estimator to show that legalization reduces students' grades, with an effect size about one-half the impact of gaining legal access to alcohol. Consistent with how marijuana consumption affects cognitive functioning, we find that students' grades fall furthest in courses that require more quantitative skills. These effects are largely driven by men and low performers. (JEL I23, I18, K32)     

TALENT AND/OR POPULARITY: WHAT DOES IT TAKE TO BE A SUPERSTAR?

We show that both talent and popularity significantly contribute to stars' market values in German soccer. The talent‐versus‐popularity controversy on the sources of stardom goes back to Rosen (1981) and Adler (1985) . All attempts to resolve the controversy empirically face the difficulty of accurately identifying talent. In professional sports, rank‐order tournaments help in ascertaining talent. Analyzing a team setting, we use 20 different performance indicators to estimate a player's talent according to his ability to increase the team's winning probability. (JEL J31, J44, L83)     

DOES IMMIGRATION INCREASE HOMICIDE?

Understanding the complex relationship between immigration and crime was once a core concern of American sociology. Yet the extensive post-1965 wave of immigration to the United States has done little to rekindle scholarly interest in this topic, even as politicians and other public figures advocate public policies to restrict immigration as a means of preventing crime. Although both popular accounts and sociological theory predict that immigration should increase crime in areas where immigrants settle, this study of Miami, El Paso, and San Diego neighborhoods shows that, controlling for other influences, immigration generally does not increase levels of homicide among Latinos and African Americans. Our results not only challenge stereotypes of the criminal immigrant' but also the core criminological notion that immigration, as a social process, disorganizes communities and increases crime.     

THE SUPPLY OF INFANTS RELINQUISHED FOR ADOPTION: DID ACCESS TO ABORTION MAKE A DIFFERENCE?

Motivated by a theory of desired fertility I use three years of aggregate state level data to examine the impact of abortion access on the supply of infants relinquished for adoption. I show evidence that abortion access affected the supply of infants relinquished during the 1980s in two different ways. First, the availability of abortion providers has the expected effect of reducing the supply of infants relinquished, particularly relative to the demand for abortion. Second, abortion law has an unexpected negative effect. This suggests that as abortion laws become more restrictive the total number of unwanted births may decrease. ( JEL J13)     

DOES THE RIVER SPILL OVER? ESTIMATING THE ECONOMIC RETURNS TO ATTENDING A RACIALLY DIVERSE COLLEGE

This article evaluates the frequently argued but heretofore little tested hypothesis that increasing minority representation in elite colleges generates tangible benefits for majority‐race students. Using data on graduates of 30 selective universities, we find only weak evidence of any relationship between collegiate racial composition and the postgraduation outcomes of white or Asian students. Moreover, the strongest evidence we uncover suggests that increasing minority representation by lowering admission standards is unlikely to produce benefits and may in fact cause harm by reducing the representation of minority students on less selective campuses. While affirmative action may still be desirable for the benefits it conveys to minority students, these results provide little support for “spillover” effects on majority‐race students.

THE INTERACTION BETWEEN MARITAL STANDARDS AND COMMUNICATION PATTERNS: HOW DOES IT CONTRIBUTE TO MARITAL ADJUSTMENT?

Couples' cognitions about marriage and their communication patterns have both been found to be highly associated with marital distress. To examine the relationships among marital cognitions, communication, and marital adjustment, we had a sample of 387 community couples complete three self-report measures: the Dyadic Adjustment Scale, the Inventory of Specific Relationship Standards, and the Communication Patterns Questionnaire. Results indicated that the correlation of communication with marital adjustment is higher for women with more relationship-focused standards than for women with less relationship-focused standards; this interaction does not occur for men. The implications of the interaction and the gender difference as well as the importance of teaching communication skills, and working with associated cognitions are discussed.     

DOES THE VAT TAX EXPORTS?

While a VAT should in principle be neutral with respect to international trade, it may in practice function as a tax on exporters' input purchases if firms receive incomplete VAT refunds. Using data for over 100 countries that span the majority of historical VAT adoption episodes, this paper finds that—consistent with this hypothesis—the VAT reduces the exports of an industry with a 10 percentage point higher intermediate goods share of output by over 8% relative to an industry with a lower share. This effect is driven by developing countries and is absent for high-income countries. (JEL F13, F14, H25, H87, O11)     

DOES DELEGATION INCREASE WORKER TRAINING?

We model a principal‐firm offering training to its agent‐worker under two alternative organizational structures: integration, where the principal retains authority to overrule the investment project recommended by the worker; and delegation, where the principal cannot overrule the worker's preferred investment project. We assume that training reduces the worker's effort cost of assembling information about alternative projects' payoffs and identify the conditions under which delegation increases the profit‐maximizing intensity of training. Empirical estimates from matched employer–employee data show that workplaces delegating authority do provide more worker training. This result persists in two cross sections, in panel fixed‐effect estimates and, critically, in an instrumental variable exercise that also controls for establishment fixed effects.

DOES NATION BUILDING SPUR ECONOMIC GROWTH?

Nation building, the allocation of economic aid conditional on military assistance in conflict and post‐conflict environments, has cost the world trillions of dollars over the last half century. Yet few attempts have been made to quantify the potential economic growth effects for the recipient country from the provision of this aid. Using a 45‐year panel dataset, we construct a measure of nation building using a three‐way interaction term between military assistance, economic aid, and conflict regime. Considering that slow growing and problem‐prone countries may be less likely to receive aid, we instrument for economic aid by estimating donor‐to‐donee aid flows in a first‐stage procedure. Using this approach, we find that spending on nation building has positive growth effects during conflict periods, but that these effects disappear after conflict. (JEL F3, F4, O5)     

DOES BEAUTY MATTER IN UNDERGRADUATE EDUCATION?

Physically attractive individuals achieve greater success in terms of earnings and status than those who are less attractive. However, whether this “beauty premium” arises primarily because of differences in ability or confidence, bias, or sorting remains unknown. We use a rich dataset from a women's college to evaluate each of these three mechanisms at the college level. We find that students judged to be more attractive perform significantly worse on standardized tests but, conditional on test scores, are not evaluated more favorably at the point of admission, suggesting that more attractive people do not possess greater abilities at the beginning of college. Controlling for test scores, more attractive students receive only marginally better grades in some specifications, and the magnitudes of the differences are very small. Finally, there is substantial beauty‐based sorting into areas of study and occupations. (JEL J16, I21, I23)     

DID EARLY TWENTIETH-CENTURY ALCOHOL PROHIBITION AFFECT MORTALITY?

We investigate the contemporaneous mortality consequences of alcohol prohibition laws introduced in America between 1900 and 1920. We improve on existing studies by constructing a time-varying measure of prohibition at the state level that corrects for the timing of prohibition enforcement and accounts for the presence of dry counties. Using summary indices that aggregate alcohol-related mortality due to disease and poor decisions, we find that prohibition significantly reduced mortality rates. These findings are corroborated with an area-level analysis that exploits data on deaths in urban areas that were wet prior to statewide or federal prohibition and nonurban areas that were partially dry.

DO MINIMUM WAGE INCREASES INFLUENCE WORKER HEALTH?

This study investigates whether minimum wage increases impact worker health in the United States. We consider self‐reported measures of general, mental, and physical health. We use data on lesser‐skilled workers from the 1993 to 2014 Behavioral Risk Factor Surveillance Survey. Among men, we find no evidence that minimum wage increases improve health; instead, we find that such increases lead to worse health outcomes, particularly among unemployed men. We find both worsening general health and improved mental health following minimum wage increases among women. These findings broaden our understanding of the full impacts of minimum wage increases on lesser‐skill workers. (JEL I1, I11, I18)     

DOES A VALUE-ADDED TAX INCREASE ECONOMIC EFFICIENCY?

Theory predicts that a value-added tax (VAT) is an efficient tax system, which is one of the primary reasons for its rapid adoption worldwide. However, there is little empirical evidence supporting this prediction, especially for developing countries. I estimate the efficiency gains of introducing a VAT using the synthetic control method. I find that a VAT has, on average, positive and economically meaningful impact on economic efficiency. This result, however, is driven by richer countries only. There is no significant impact of the VAT on poorer countries. The findings are robust across a series of placebo studies and sensitivity checks. (JEL H20, H25, O40, E6)     

DOES A GOOD CENTRAL BANKER MAKE A DIFFERENCE?

The personalities of central bankers moved center stage during the recent financial crisis. Indeed, several central bankers even became “superstars.” In this article, we investigate whether superstar central bankers have an impact on economic performance. We employ school grades given to central bankers by the financial press, defining as superstars those central bankers receiving the top grade. First, we explain the grades in a probit estimation with measures of economic performance, institutional features, and personal characteristics. Second, we employ a matching approach to account for the endogeneity of grading with respect to economic performance. Using entropy balancing, we identify credible counterfactuals for top‐graded central bankers, that is, nonsuperstar central bankers who face similar situations. Comparing the economic performance of both groups, we find that superstars do indeed matter: a top‐graded central banker faces a significantly more favorable output‐inflation tradeoff than his peers. This effect is driven by outstanding central bankers in both advanced and emerging economies and is especially prevalent in the precrisis subsample. (JEL E52, E58)     

ARE WORKERS WILLING TO PAY TO JOIN A BETTER TEAM?

Using data from the Major League Baseball free‐agent market, this study is the first to show that the productivity expected of the team a worker will join produces a significant, negative compensating wage differential. The younger workers in the sample drive this result, trading 25% of their wages to join teams with an expected productivity one standard deviation higher. This investment can be recouped if a reasonable increase in human capital occurs. These results are robust to contract length‐wage simultaneity and indicate that investment in human capital motivates the observed tradeoff, suggesting a new pathway through which human capital accumulation can affect wages. Reliable measures of workers' own past productivity and the productivity expected of a worker's future team provide key advantages to identifying these effects. (JEL J31, J24, M54)
