Coauthorship and publication efficiency

This study extends a recent paper by Jean Louis Heck and Peter A. Zaleski [1991] on trends in economics journal publication from 1969–89. The primary purpose of the work is to analyze the impact on article production of an observed dramatically increasing tendency toward coauthorship among scholars in economics. A simple model is tested with total (per capita) articles as a function of time, American Economic Association (AEA) membership, and articles coauthored per year. Results suggest that the increasing trend toward coauthorship enhances productivity in total and per-capita article production. The authors would like to thank Gary Shelley, Janet K. Smith, Peter Zaleski, and an anonymous referee for comments on previous versions of this paper.     

Advertising as Information: Matching Products to Buyers

We consider communication of quality via cheap talk and dissipative advertising expenditures, when consumers have heterogeneous tastes for quality, and price information must be acquired through costly search. For search pods, cheap talk communicates quality when fixed costs are roughly constant across quality levels, while if fixed costs vary greatly with quality, then firms having the higher fixed-cost quality level use dissipative advertising. For experience goods, quality can be communicated by cheap talk in a range where low-quality firms have greater fixed costs, and low-quality firms use dissipative advertising if their fixed costs are greater still.     

Recurrent trade agreements and the value of external enforcement

This paper presents a theory of dynamic trade agreements in which external institutions, such as the WTO, play a central role in supporting credible enforcement. In our model, countries engage in ongoing negotiations, and, as a consequence, cooperative agreements become unsustainable in the absence of external enforcement institutions. By using mechanisms such as delays in dispute resolution and direct penalties, enforcement institutions can restore incentives for cooperation, despite the lack of coercive power. The occurrence of costly trade disputes, and the feasibility of mechanisms such as escape clauses, depend on the degree to which enforcement institutions can verify, and condition on, events that may lead to trade disputes.     

Motivations for Activity Participation as Predictors of Emerging Adults' Psychological Engagement in Leisure Activities

Psychological engagement has been identified as a critical factor in the potential benefits of emerging adults. leisure activity participation. Emerging adults. motivations for participation might be particularly important in predicting psychological engagement. In the present work, we report findings from a study of motivations for leisure participation and its associations with psychological engagement. In a sample of 183 undergraduate university students, we found that three of the five hypothesized motivators positively and significantly predicted greater psychological engagement. Specifically, greater psychological engagement was related to leisure participation motivated by a desire to learn and exercise skills and abilities, protect the self (for example, to alleviate guilt by helping others), and because of opportunities presented by others. favorable attitudes towards involvement.     

More on the Cost of Being Other Than White and Male:

ABSTRACT This article analyzes the estimated yearly earnings of white, black, and Hispanic males and white, black, and Hispanic females in order to determine two things: Whether white male earnings continue to exceed those of reference groups, and how the cost of being female (the gender effect) compares with the cost of being nonwhite (black or Hispanic). We find that white males earnings are still greater than those of other groups, but when earnings are adjusted for market related differences, most of the differentials for black and Hispanic (Mexican-American, Puerto-Rican) males disappear. Even after adjustment, however, a considerable portion of females earnings differentials remain unexplained. Gender effects are considerably larger than race or ethnic effects.     

A method for identifying the most influential articles in an academic discipline

This paper develops a methodology, based on citation counts, for classifying journal articles as highly-cited, pre-classic, classic and super-classic. In order to establish the benchmark measures necessary for such classification, a citation analysis was done of all main articles produced in the American Economic Review from 1965 through 1985. Using the established benchmarks, 127 articles published during the review period met the minimum criteria for at least highly-cited status. In addition, a subset of 17 articles were designated as either classic or super-classic. An additional 11 articles were on a yearly citation pace to become classics and were classified as pre-classic. A few of the characteristics of these papers are noted. Evidence from other studies is presented to support the methodology developed here.The authors are grateful to Tim Perri, Fred Wallace and David Laband for helpful comments on an earlier version of this paper.     

Adaptive expectations, underparameterization and the Lucas critique

A striking implication of the replacement of adaptive expectations by rational expectations was the “Lucas critique,” which showed that expectation parameters, and endogenous variable dynamics, depend on policy parameters. We consider this issue from the vantage point of bounded rationality, where for transparency we model bounded rationality by means of simple adaptive expectations. We show that for a range of processes, monetary policy remains subject to the Lucas critique. However, there are also regimes in which the expectation parameter is locally invariant and the Lucas critique does not apply.     

James Buchanan's contributions to social and economic thought: Citation counts,self-assessment,and peer review

This paper demonstrates James Buchanan's impact on socio-economic thought through citation analysis of his published works, a discussion of Buchanan's own views of what his work means and is, and summary discussions of the assessments of other scholars. Thus the central themes of his work are illuminated as well. These themes include a deep distrust of government interference in the economy and in the personal lives of members of the polity, and his absolute conviction that collective decisionmaking should take place only within the framework of a contractual agreement, the fundamental principles of which have been derived through near unanimity.
