INNUMERACY ABOUT MINORITY POPULATIONS

We use a small but nationally representative sample to investigatethe sources of innumeracy regarding the proportion of blacks,Hispanics, and Jews in the U.S. population. In addition to anumber of standard demographic differences, we find that overestimatesare closely related to region as well as to the density of thelocal black/Hispanic population. The extent to which minoritypopulations are perceived as a kind of threat is also relatedto perceived proportions, though the direction of causalitycannot be determined. We discuss the meaningfulness of thesepopulation estimates and speculate on whether trying to improvethem would alter attitudes toward minorities.     

A closed loop automatic scheduling system (CLASS)

Abstract

CLASS is a production scheduling system, that is designed to function in either a stand-alone manner, or in conjunction with an MRP system. MRP systems innately do not have 'closed loop’ capability in the sense of being able to produce master schedules and order releases that are consistent and that respect capacity constraints. True closed loop performance requires detailed scheduling. In addition to interfacing with MRP systems, CLASS is designed to produce schedules that can be used in conventional shops or can be downloaded to automated facilities. The design goals for the system, its internal architecture, and its role in manufacturing control systems are described. The modelling and decision capabilities     

THE IMPACT OF TRADE COSTS ON FIRM ENTRY,EXPORTING, AND SURVIVAL IN KOREA

This study examines how changes in trade costs have affected entry, exit, productivity, and exporting in the Korean manufacturing sector. We verify several predictions of heterogeneous‐firm models of international trade. For example, falling import‐trade costs are associated with less entry and lower market shares among existing domestic firms, and higher total factor productivity for Korean manufacturing as a whole. The size of firms plays an important role in many of our results. New domestic firms are more likely to be small, but large firms are less likely to exit and more likely to have an increase in total factor productivity. (JEL F10, D24)     

THE IMPACT OF ENTITLEMENTS AND EQUITY ON COOPERATIVE BARGAINING: AN EXPERIMENT

In some bargaining situations—for example, collaborative policy making and compulsory arbitration—a third party imposes a backstop position that differs from the status quo. Axiomatic models of cooperative bargaining presume that the status quo in such cases will have no effect on the negotiated outcome, especially if it is Pareto inferior to the backstop. Recent literatures on equity and entitlement, however, suggest that the status quo may establish a focal point that acts as an “anchor” in current negotiations, affecting any ultimate agreement. In a two‐party, two‐attribute experiment, in which subjects jointly select from up to 200 options, we find evidence (1) that the status quo matters, perhaps because of “entitlement effects” and (2) that parties prefer egalitarian outcomes to the Nash bargain.

INFLUENCE OF AN INVITATION TO ANSWER BY TELEPHONE ON RESPONSE TO CENSUS QUESTIONNAIRES

An experimental test was made of whether completion rates fora census questionnaire could be improved by offering the optionof calling a toll-free number and providing the requested informationto an interviewer as an alternative to mailing it back. Conductedon a national probability sample of house holds, five treatmentpanels were created to examine the effect of delivering, indifferent ways, the invitation to respond by telephone or mail.Offering such invitations did not improve completion rates exceptwhen included with a follow-up letter that did not also includea replacement questionnaire.     

TAXONOMY AND THE EFFECTS OF FISCAL AND MONETARY POLICY

This paper reviews the development of monetarist theory and the circumstances under which emphasis shifted to "fiscalism," discusses Bent Hansen's view that the controversy is largely a sham dispute, and suggests two types of research needed to assess, historically and theoretically, the relative practical importance of the two approaches to reduction or elimination of economic instability.
