ACADEMIC PUBLICATION, MARKET SIGNALING, AND SCIENTIFIC RESEARCH DECISIONS

Publication is an essential scientific activity, but dangers arise when it is the primary signal of professional ability. This paper presents a simple model of screening in academic job markets. Signaling pressures may bias research decisions toward orthodox, low-risk projects, denying science the bold hypotheses and vigorous competition necessary for significant advance. Screening mechanisms help explain patterns of development noted by some historians of science as well as differences in these patterns across disciplines. The paper concludes with some comments on signaling and scientific change in economics.     

LABOR FORCE MIGRATION AND ALLOCATIVE EFFICIENCY IN THE UNITED STATES: THE ROLES OF INFORMATION AND PSYCHIC COSTS

This paper examines the relative importance of information, psychic and other costs of relocation as mitigating factors (off-sets to spatial earnings differentials) within the migration decision. The methodology employed for this examination is based upon: (1) observation of relationships between the geographic allocation and personal characteristics of labor force migrants, and (2) inferences, drawn from these observations, on the relative importance of various relocation cost components. Empirical analyses of the migration decision based upon this indirect methodology provide important insights on both the determinants and allocative efficiency of interstate labor force migration in the United States.     

AN EXPLORATORY STUDY OF PATTERNS OF PRIORITIES AND TRADE-OFFS AMONG OPERATIONS MANAGERS

A survey of 15 firms showed that agreement among operations managers on competitive priorities is related to agreement on long-run strategic trade-off decisions and not to agreement on shortrun trade-offs. Furthermore, intended short-run actions were often in conflict with stated competitive priorities. Use of management-by-objectives linked to performance appraisal was related to agreement on competitive priorities.     

RISK TAKING IN CONTESTS AND THE ROLE OF CARROTS AND STICKS

We study contests in which contestants choose both work effort and the variance of output (risk). Winner-take-all contests generate incentives for contestants to engage in costly risk taking, which is inefficient if the contest organizer values the aggregate output of all contestants. The addition of a penalty for ranking last (retaining a prize for ranking first) enables the organizer to independently control contestants' incentives to exert productive effort and to increase output variance. In this way, the organizer can eliminate risk-seeking behavior in settings where it is wasteful, but also control risk seeking when it is desirable, such as in research tournaments.

The Relationship Among Body Mass,Wealth, and Inequality Across the BMI Distribution: Evidence From Nineteenth-Century Prison Records

Nineteenth-century U.S. Black and White body mass indexes (BMIs) were distributed symmetrically; neither wasting nor obesity was common. BMI values were also greater for Blacks than for Whites. During industrialization in the nineteenth century in the United States, there was a negative relationship between BMIs and average state-level wealth and an inverse relationship between BMI and wealth inequality. After controlling for wealth and inequality, rural agricultural farmers had greater BMI values than their urban counterparts in other occupations.     

PARENTAL SUBSTANCE USE AND FOSTER CARE: EVIDENCE FROM TWO METHAMPHETAMINE SUPPLY SHOCKS

Foster care caseloads have nearly doubled over the last three decades. Parental methamphetamine (meth) use grew significantly during the same period. While child welfare workers and law enforcement claim that parental meth use contributes to foster care growth, the evidence for a causal effect has not been determined. This paper presents the first evidence of a causal effect of meth on foster care admissions using two exogenous supply‐side interventions in meth markets from the late 1990s for identification. First, we find that restrictions on meth precursor distribution caused meth use (proxied by white meth self‐referred treatment cases) to decline 4.1%. Second, using two‐stage least squares, we estimate a positive elasticity of foster care cases with respect to meth use of 1.54. We also estimate elasticities of 1.03 and 1.49 for cases of child neglect and parental abuse, respectively. These results suggest that child welfare policies should be designed specifically for the children of meth‐using parents. (JEL I12, J13, K42)
