Optimal fiscal zoning when the local government is a discriminating monopolist

Monopoly zoning by local governments has been studied extensively since the original article by White [1975, in: E. Mills and W. Oates, eds., Fiscal zoning and land use controls (Lexington Books, Lexington, MA)]. However, little or no attention has been paid to the possibility of monopolistic discrimination under such a regime. The question is: When will zoning multiple lot sizes be feasible given that buyers with different valuations of land cannot be coerced into purchasing particular lots? The literature on imperfect price discrimination by monopolists is brought to bear on this question. It is shown that the resulting zoning strategy may or may not involve multiple lot sizes. The factors determining the optimal strategy are studied in detail, with particular emphasis on the nature of the market for undeveloped land in the community.     

Alternative sources of technology: An analysis of induced innovations

This paper considers why firms differ in the degree to which they rely on their internal R&D organization for generating new technologies (induced innovations) rather than on existing external technology markets (purchased innovations). An empirical model is suggested to explan inter-firm differences in the percentage of new technology induced through R&D efforts. The analysis suggests that such differences are systematically related to the firm's size, its competative environment, and its degree of diversification.     

Analysis of arrest rates for trends in criminality

During the 1960s, the United States experienced a substantial increase in crime with the rates of reported crime more than doubling. It has been postulated that the increase in the proportion of young adults in the population which also occurred during the Sixties is a primary factor in the increase in crime. In this paper, we attempt to explore this question by partitioning the recent increases in rates between an increasing crime-committing propensity for various demographic groups on one hand, and a changing demographic mix to the other. We do this by analyzing arrest rates by demographic group over time. However, since arrest rates are a complex function of both criminality and police activity, a model is developed which attempts to distinguish between these phenomena. The model is estimated using data on age, race, and sex-specific arrest rates for Pittsburgh residents over the period 1967–1972. The results of the analysis suggest that there has been no significant increase in criminality for men in the Pittsburgh population, while there is some evidence of increased criminality for women. However, this increase may reflect an increased willingness of the police to arrest women. We hesitate to generalize our conclusions too widely from the experience of a single urban center. Additional analysis, using the model developed here, of arrest rates from other cities or regions would do much to illuminate this very significant issue.

Monotonizing empirical Bayes estimators for a class of of discrete distributions with monotone likelihood ratio

A procedure is given for the construction of a monotone estimator that dominates a given estimator for a class of discrete distributions with monotone likelihood ratio. This procedure is applied to some empirical Bayes estimators. Monte Carlo results are given that demonstrate the usefulness of monotonizing.     

A comparison of approximately optimal stratification given proportional allocation with other methods of stratification and allocation

Summary In this article, we shall present an approximately optimal method for constructing stratum boundary points when the sample is allocated proportionally. The method is based on an equal partitioning of the cumulative off ^1/3, wheref is the distribution of the stratification variable. We show that in many practical situations this technique compares favourably with approximately optimal stratification and allocation methods previously suggested.

Zusammenfassung In diesem Artikel stellen wir eine annähernd optimale Methode zur Festlegung von Stratabegrenzungspunkten dar, die für proportional angeordnete Samples gilt. Die Methode basiert auf einer gleichen Einteilung derf ^1/3-Kummulation, wobeif die Verteilung der Stratifikations-variablen darstellt. Wir zeigen, daß diese Technik in vielen praktischen Fällen gegenüber den bisher vorgeschlagenen Methoden zur optimalen Stratifikation und Zuordnung nicht schlecht abschneidet.

     

The economics of decision making in the new manufacturing firm

Decision making in a modern manufacturing firm producing a variety of products while meeting order deadlines appears at first to have little basis in the economic Theory of the Firm. It is shown that optimal budget allocations, the fractions of revenue expended on inputs, are likely to remain constant for a succession of orders for each of a family of products, thus simplifying the decision process. Well-known heuristic decision rules may not only have a sound basis in economic theory but are evidently the best way to incorporate economic logic into a stream of fast-moving decisions. The discussion is extended to an explanation of the economic value of decision making to the firm, and why this value is usually assumed to be zero in theory.     

Aggregation effects on price and expenditure elasticities in a quadratic almost ideal demand system

Abstract.  While it is well known that demand elasticities calculated at the macro level will in general differ from those calculated at the micro level because of aggregation effects, there remain the questions of how large the effects are and how they vary with the degree of inequality in the income distribution. We explore these questions with models based on a quadratic version of the Almost Ideal Demand System. We investigate the elasticity differences theoretically and then calibrate the models and generate numerical results, using income data for seven countries with widely different distributions. The aggregation effects are found generally to be rather small, even with highly unequal income distributions.
