Aggregation effects on price and expenditure elasticities in a quadratic almost ideal demand system 总被引:1,自引:0,他引:1
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

The relation between immigration and the economic welfare of residents b analyzed for resource-rich economies (such as Australia) both under competitive conditions and when various distortions are present Immigration provides efficiency gains for residents under distortion–free competition for standard ‘gains from trade’ reasons. Such reasons, however, tend to be ignored by immigration and ‘optimal population’ theorists who raise the issue of restricting immigration without explicitly referring to the distortions. In situations where distortions and externalities are present, we argue that it is generally preferable to devise policies which specifically target the distortions than to restrict immigration. 相似文献

The recent papers by Guesnerie and Diewert on tax reforms are interpreted as contributions to the characterization of second-best optima. This paper demonstrates that when it is possible to achieve any feasible direction of change in supplies by a differential change in producer prices, there are unique producer support prices. Under these circumstances, the apparent differences between Guesnerie and Diewert are reconciled. Optimality conditions with nonunique support prices are also considered. 相似文献
