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.     

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.     

Northern Ireland children and cross-community holiday projects

SUMMARY: Holiday projects have made a contribution to cross-community relations in Northern Ireland for 20 years. During that troubled time they have evolved approaches which have increasingly featured contact between the children involved. This paper. bared largely on interviews with organisers and children on holiday projects visiting America in 1989, concentrates upon the essential follow-up component arranged back in the Province. While some emphasis is made on the application of the so-called ‘contact hypothesis’ to this area within the voluntary sector, the study reveals the challenge that holiday projects must now face in raising and handling controversial issues among children from different cultural backgrounds in a conflict society.     

A MARKET-BASED TEST OF THE EFFECT OF MONETARY POLICY

This paper tests the rational expectations-natural rate hypothesis without basing expectations on time series estimates. Instead, market-based data are used. Unexpected money supply changes are determined via the Fisher Effect and the Quantity Equation. This introduces errors of a very different kind than the traditional approach, and yet the results are remarkably similar to those generated using time series estimates. Unanticipated money shocks are shown to exert a significant but only short-run effect on real output, suggesting only a short-run Phillips curve trade-off. Anticipated money growth appears to have no effect on real output.
