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.  相似文献

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.  相似文献

This study is concerned with one aspect of the family cycle, namely, the transition from young married to young married with small children. The focus is on developing models to forecast entries into this latter stage for the purpose of marketing research. "Using ordinary least squares, forecasting models were estimated for (1) total number of first births, (2) number of white first births, and (3) number of nonwhite first births." Models are estimated for both the United States and California using data from official sources.  相似文献

On the simple model of a (univariate) random process some general problems of “random logic” are discussed. New random approaches to explorative, normative and systematic (normex) forecasting are developed, and some applications are suggested.  相似文献

A bstract . Orthodox economics has been quite effective in exploiting equilibrium methodology; equilibrium as a heuristic device, as a theoretical norm, and as a prototype of the scientific method. Also, orthodoxy has contrived the dichotomy of equilibrium-anti-equilibrium to depict institutional thought as being muddled and unscientific. Institutionalists have not successfully countered these attacks, nor have they adequately articulated a comprehensive methodological alternative to orthodoxy. Institutionalists have paid too much attention to the methodological components of institutionalism and have neglected the articulation of a guiding, overall methodology. It is proposed that institutionalists recast the methodological debate by expanding the arena from equilibrium-anti-equilibrium analysis to the broader context of closed versus open systems analysis. This would both help expose the methodological weaknesses of orthodox economics, and demonstrate the relevance and power of institutionalism for socioeconomic investigation.  相似文献

In a model of economic ‘clubs’, size is fixed and members consuming a public good raise the question of composition; with whom would they rather consume? This depends on the way collective consumption is financed, and three results are proven With a poll tax, clubs must be homogeneous in income for all to be satisfied With a marginal benefit (Lindahl) tax, no consumer is ever satisfied with any composition; and with an income tax, at least one consumer in each club is always dissatisfied. Satisfaction implies there exists no club composition preferred to the existing one.  相似文献

In recent years there has been a growing number of input-output models of economies ranging in scale from the rural to the national. While offering invaluable insights into the interaction of sectors within an economy, the input-output model suffers from the fact that its coefficient values are altered over time due particularly to technological change. Two of the prominent techniques designed to update these technical coefficients, the RAS and linear programming methods, are compared herein with regard to changes in U.S. national coefficients between 1963 and 1967. Suggestions for improvements to the latter method are outlined.  相似文献
