ADMINISTERED INFLATION: A REAPPRAISAL

Several empirical studies have tested and confirmed the administered inflation hypothesis for both the United States and Canada. A close examination of these tests reveals that different authors using similar methods and data sources have reported opposite test results as support for the same theory. This suggests a reconsideration of the theory and the methods of prior tests. This study presents some theoretical objections to the concept of administered inflation, points out several inconsistencies in previous empirical tests and retests the data.     

THE IMPACT OF TELEVISION VIEWING ON MENTAL APTITUDE AND ACHIEVEMENT: A LONGITUDINAL STUDY

Previous studies of the effects of telecision viewing on mentalabilities have shown mixed results, but most suffered from oneor more of the following shortcomings: a small or other-wiseunrepresentative sample, a cross-sectional rather than longitudinalapproach, and a failure to consider intervening variables betweentelevision viewing and cognitive skills. This study was designedto overcome these deficiencies by using nationally representativedata from the National Health Examination Cycle 2 and Cycle3 Surveys. These surveys included 1,745 children who were studiesboth when 6 to 11 years old (between July, 1963, and December,1965) and about four years later when 12 to 17 years old (betweenMarch, 1966, and March, 1970). Simple analysis at just one time-pointreveals substantial relationships between the amount of televisionviewing and depressed IQ and Wide Range Achievement Test (Readingand Arithmetic) scores of adolescents. When longitudinal controlsare added, however, these relationships become statisticallyinsignificant and substantively unimportant. Although thesedata are 20 years old, they indicate no significant causal relationshipbetween the amount of television viewed and the mental aptitudeand achievement test scores of adolescents, thus supportingand extending Gaddy's (1986) recent longitudinal study of anational sample of youth.     

Welfare, Society and the Social Worker

Summary This article attempts to locate some common stereotyped transactionsbetween social workers and their clients as elements in theproduction of distinctive welfare identities. By comparing thisprocess to that of a rite of passage, the client is found tobe like a ritual subject frozen in the moment of transitionbetween social categories and thereby denied a place in society.An opposition is accordingly presumed to exist between Welfareand Society. The matrix of stereotyped expectations which derivesfrom this opposition is shown often to intrude on the relationshipbetween social worker and client, constituting a pressure toresolve the tensions produced by anomaly through the impositionof a welfare identity on the client. In this respect, the specialvulnerability of marginal groups is noted and a brief discussionthen follows of the characteristic qualities of ascribed welfareidentity. Through Welfare, Society is found to displace imaginativelyits sense of entropy beyond the moral community. But the essentiallink between Welfare and Society remains and increasing socialdisorder brings the paradoxical feature of this strategy tothe fore. The preservation of the social order requires increasingconcentrations of entropy to be symbolically located in Welfareand as a result Welfare comes to take on the aspect of a threateningand subversive entity. In conclusion, it is suggested that behindthe apparent ‘crisis’ in social work lies a crisisin the management of social entropy.     

SELECTING A SELLING INSTITUTION: AUCTIONS VERSUS SEQUENTIAL SEARCH

We consider the seller's choice between sequential search and an auction when selling n homogeneous units of a good in the presence of informational asymmetries, discounting, and transaction costs. Our analysis shows that the expected return per unit from sequential selling decreases in n, the number of units being sold. For the auction with suitable restrictions, the expected return per unit increases in n. Thus, sequential search is the preferred institution if n is small, whereas the auction is preferred if n is large. Historical details of the evolution of livestock markets closely fit our theoretical results.     

DONOR PREFERENCES AND RECIPIENT FISCAL BEHAVIOR: A SIMULTANEOUS ANALYSIS OF FOREIGN AID

We theoretically develop and empirically estimate a preference model determining foreign aid donor behavior. Aid access and levels are separately determined by endogenous budgetary allocations, the international economic environment, the distribution of income between countries, basic human needs, the small country effect, and regional bias. We find fungibility of aid in recipient budgets is due to donor and recipient preferences. Despite the importance of other economic influences, we find a significant pro-poor country bias in aid allocations, although little aggregate influence of basic human needs or regional bias. The small country effect is significant for two (of six) donors. (JEL F35, O19, H 77)     

SPECULATIVE INTENSITY AND SPOT AND FUTURES PRICE VARIABILITY

This paper develops a simultaneous stochastic rational-expectations model of futures- and spot-price determination. Using the model, we find that increases in what we term speculative intensity increase spot-price variability arising from storage-cost shocks, but decrease spot-price variability arising from demand shocks. In contrast, increases in speculative intensity unambiguously decrease futures-price variability, regardless of the underlying source of disturbances. We are able to develop these comparative-static results because the model has a unique equilibrium.     

ROOFS OR STARS: THE STATED INTENTS AND ACTUAL EFFECTS OF A RENTS ORDINANCE

As a consequence of a law designed to keep roofs over the heads of resident tenants, some of these tenants were now sleeping out under the stars.
