In this paper, I investigate the competitive and welfare effects of the improvements in information accuracy in markets where firms can price discriminate after observing a private and noisy signal about a consumer's brand preference. I show that when firms believe that consumers have a brand preference for them, then they charge more to these consumers, and this price has an inverse U‐shaped relationship with the signal's accuracy. In contrast, the price charged after a disloyal signal has been observed falls as the signal's accuracy rises. While industry profit and overall welfare fall monotonically when price discrimination is based on increasingly more accurate information, the reverse happens to consumer surplus.  相似文献

This paper attempts to reconstruct and assess the intellectual itinerary of Hicks on the valuation of social income. His 1958 and 1981 papers on that topic have been wholly ignored in the economic literature. In both of them differentmeasures of real income are provided. These show to what extenteach one of them can be relied upon. Our assessment argues that it is impossible to measure social income independentlyof the reasons for which that measure is required and that any valuation cannot ultimatelybe made independently of political and ethical considerations.  相似文献

In this paper, we modify the Djajić [Djajić, S., 1987. “Government Spending and the Optimal Rates of Consumption and Capital Accumulation,” Canadian Journal of Economics 20, 544–554.] model in such a way that government consumption expenditure provides utility to households via the total stock of government services rather than the government consumption flow alone. By using such a framework, we show that the optimality condition for the public service capital stock is the marginal rate of substitution between public service capital and consumption that equals the intertemporal marginal rate of transformation between the two goods. In addition, we show that the relationship between private consumption and public service capital in a household's utility plays an important role in determining the transitional behavior of relevant variables. We also examine the second-best government consumption expenditure policy. By contrast, in the standard flow specification, e.g., Turnovsky and Brock [Turnovsky, S.J. and Brock, W.A., 1980. “Time Consistency and Optimal Government Policies in Perfect Foresight Equilibrium,” Journal of Public Economics 13, 183–212.], Ihori [Ihori, T., 1990. “Government Spending and Private Consumption,” Canadian Journal of Economics 23, 60–69.], and Turnovsky and Fisher [Turnovsky, S.J. and Fisher, W.H., 1995. “The Composition of Government Expenditure and its Consequences for Macroeconomic Performance,” Journal of Economic Dynamics and Control 19, 747–786.], the second-best government consumption expenditure is decided on the basis that the marginal utility of consumption is equal to the discounted sum of the marginal utility of the government's flow spending.  相似文献

This note analyses the effect of the policy of tightening Intellectual Property Rights (IPR) on the rate of innovation in the North and on the welfare in both North and South in a model which is otherwise identical to Helpman (1993) except in the concept of knowledge capital. We assume that the South based imitated products do not contribute to the knowledge capital in the North. It is shown that the tightening of IPR raises the rate of innovation in the North and may improve the welfare of both North and South. These results are significantly different from those in Helpman (1993).  相似文献

基于省级和国家层面的宏观数据,分别构建了产业集聚和社会福利发展水平的综合评价指标体系,利用脱钩理论分析了我国航空航天制造产业的集聚效应及其与社会福利发展水平之间的关系。研究表明:航空航天制造业在东部地区发展迅猛;产业集聚的总体水平呈现下降趋势;集聚效应所带来的社会福利总体发展水平呈现下降的趋势,直接福利和间接福利并没有得到同步发展;产业集聚和社会福利发展水平多为同向变化,集聚福利脱钩指数呈现下降趋势;进入管制政策在一定程度上能够促进产业发展。  相似文献

Very many statements have been made about the (non-)existence and characterisation of the ‘marginal revolution’ but it is urged here that detailed study of the relevant texts is far more valuable than the making of grand statements about such matters. In particular, a close reading of Jevons's Theory of Political Economyis proposed as an antidote to over-easy generalisation. Jevons by no means rejected all elements of classical theory. He did not propose a catallatic revolution; he attributed such an emphasis to earlier authors and himself stressed the role of production. It is shown that Jevons was very aware of the necessarily general equilibrium nature of his theory but that he was simply not able to cope with it satisfactorily; it is suggested that this explains, at least in part, his fluctuating and apparently inconsistent statements relating utility and labour to value. Jevons certainly attempted to sketch a complete marginal productivity theory of distribution, even if he was far from successful in providing one.  相似文献

Conventional wisdom is that a binding price ceiling increases output and so increases social welfare if imposed on an imperfectly competitive market. However, this paper shows that a price ceiling can be harmful to social welfare even though it increases industry output and consumer surplus. This model can be applied to the pharmaceutical industry under price control in many countries, e.g., U.K., Canada, Germany and Japan.  相似文献

Using the integer programming approach introduced by Sethuraman et al. (2003), we extend the analysis of the preference domains containing an inseparable ordered pair, initiated by Kalai and Ritz (1978). We show that these domains admit not only Arrovian social welfare functions “without ties,” but also Arrovian social welfare functions “with ties,” since they satisfy the strictly decomposability condition introduced by Busetto et al. (2015). Moreover, we go further in the comparison between Kalai and Ritz (1978)’s inseparability and Arrow (1963)’s single-peak restrictions, showing that the former condition is more “respectable,” in the sense of Muller and Satterthwaite (1985).  相似文献

In each period of a dynamic tax-rebate program, a (fixed) quantity tax is imposed on each unit of a given good, and the tax revenue is rebated back to the consumer in the next period. The program lasts for infinite number of periods. The author considers a representative consumer's dynamic consumption behavior, the long-run steady-state consumption, and the consumer's welfare. Under the standard continuity and strict convexity assumptions on the consumer's preferences, he shows that the tax strictly reduces the consumption of the good in each period as well as in the steady state, and the consumer is strictly worse off. He also provides numerical analysis when the consumer has the quasilinear or the Cobb-Douglas utility functions.  相似文献
