An Anatomy of Price Dynamics in Illiquid Markets: Analysis and Evidence from Local Housing Markets

This research analyzes the dynamic properties of the difference equation that arises when markets exhibit serial correlation and mean reversion. We identify the correlation and reversion parameters for which prices will overshoot equilibrium ("cycles") and/or diverge permanently from equilibrium. We then estimate the serial correlation and mean reversion coefficients from a large panel data set of 62 metro areas from 1979 to 1995 conditional on a set of economic variables that proxy for information costs, supply costs and expectations. Serial correlation is higher in metro areas with higher real incomes, population growth and real construction costs. Mean reversion is greater in large metro areas and faster growing cities with lower construction costs. The average fitted values for mean reversion and serial correlation lie in the convergent oscillatory region, but specific observations fall in both the damped and oscillatory regions and in both the convergent and divergent regions. Thus, the dynamic properties of housing markets are specific to the given time and location being considered.     

Agricultural Extension: Good Intentions and Hard Realities

What considerations lead policymakers to invest in agriculturalextension as a key public responsibility, and what factors andagency incentives explain differences in extension system performance?To help answer these questions, this article provides a frameworkoutlining farmers' demand for information, the public goodscharacter of extension services, and the organizational andpolitical attributes affecting the performance of extensionsystems. This conceptual framework is used to analyze severalextension modalities and their likely and actual effectiveness.The analysis highlights the efficiency gains that can come fromlocally decentralized delivery systems with incentive structuresbased on largely private provision, although in most poorercountries extension services will remain publicly funded.      

Attitudes of Businessmen,Consumers, and Consumerists Toward Consumerism

Despite the apparent concern about consumerism issues by various groups, it appears that much of this concern has been based on speculation and casual observations. There is a paucity of empirical research regarding attitudes toward consumerism. This study is the first to assess the attitudes of businessmen, consumers and consumerists—all from the same geographic and market environmenttoward several important consumerism issues. The results, which show significant differences in various areas, have important policy implications for consumerists, politicians and businessmen.     

Zur Qualität der Medienkontrolle: Ergebnisse einer Befragung deutscher Rundfunk- und Medienräte

This article presents the results of a survey among German media supervisors (members of supervising boards in public broadcasting stations and state media institutions). Given the increasing commercialization and internationalization of television, the supervising boards play a crucial part in assessing the quality of programs. From among 940 German supervisors, 364 took part in the survey, which covered the individual role conceptions of respondents as well as their attitudes towards quality criteria for television. Results suggest that both the supervisors’ amount of television use and the types of programs they prefer is clearly different from patterns in the population. This, along with the observation that supervisors often criticize what they saw privately, suggests (given the diversity of programs) that too much might be expected of them. Media supervisors do heed quality criteria in their work, but these probably do not correspond to other groups’ criteria, and especially not to the general population’s. To conclude, suggestions are discussed to improve the system of supervising programs by important social groups.
