The incorporation of diverse information into asset prices isempirically examined in an actual securities market with multiplerounds of trade. Using prices of Israeli index and nominal bondsof equal maturity, we calculate implied expectations of inflationthat has already occurred but for which the official statistichas not yet been announced. Learning is defined as the convergenceof these expectations to the actual level of inflation in theperiod after the end of the month but before the announcementof the official statistic. We find that the variance of theinflation expectation errors decreases with trading days inthis period. The decline in the variance suggests that investorslearn, by repeatedly observing prices, about the distributionof other investors' information. We also find a positive relationbetween the dispersion of relative price changes and the sizeof the inflation-expectation errors on the first round of trade.The correlation diminishes as investors learn about the distributionof inflation information in the economy. 相似文献

The Distribution of Human Capital and Economic Growth 总被引:16,自引:3,他引:16
This paper analyzes the interaction between the distributionof human capital, technological progress, and economic growth.It argues that the composition of human capital is an importantfactor in the determination of the pattern of economic development.The study demonstrates that the evolutionary pattern of the humancapital distribution, the income distribution, and economic growthare determined simultaneously by the interplay between a local home environment externality and a global technologicalexternality. In early stages of development the local home environmentexternality is the dominating factor and hence the distributionof income becomes polarized; whereas in mature stages of developmentthe global technological externality dominates and the distributionof income ultimately contracts. Polarization, in early stagesof development may be a necessary ingredient for future economicgrowth. An economy that prematurely implements a policy designedto enhance equality may be trapped at a low stage of development.An underdeveloped economy, which values equality as well as prosperity,may confront a trade-off between equality in the short-run followedby equality and stagnation in the long-run, and inequality inthe short-run followed by equality and prosperity in the longrun. 相似文献

Status Aspirations, Wealth Inequality, and Economic Growth 总被引:1,自引:0,他引:1
Oded Stark 《Review of Development Economics》2006,10(1):171-176
This paper argues that an increase in the inequality of wealth prompts a stronger quest for status that in turn fosters the accumulation of wealth. It proposes a measure for an individual's want of social status. For a given level of a population's wealth, the corresponding aggregate measure of want of social status is shown to be positively related to the Gini coefficient of wealth inequality. Hence, the Gini coefficient and growth are positively correlated, holding the population's wealth constant. 相似文献

A general equilibrium model of an economy with cities, farms and free migration of population is constructed. The cities produce internationally traded goods via production functions subject to economies of scale. They also produce housing and a local public good. Two areas are defined to be disjoint if households performing an economic activity in one area are not operating in the other. An area is exclusive if it is disjoint to its complement. The economic surplus of an area is then defined to be the value of the area's net export of goods and resources. Local efficiency of an area is defined to be a state in which its economic surplus attains its maximum value. This state is proved to be a necessary condition for Pareto optimality of the economy. It is then proved that beside Piguvian corrective taxes the only taxes necessary and sufficient to finance local government activities efficiently, are taxes on land rents. Furthermore, if jurisdiction of a local government is over an exclusive area no intervention of central government is necessary, and local authorities can be fully autonomous. If the economy can be divided into pairwise disjointed exclusive areas, those areas are optimal jurisdictions in the sense that efficiency in the economy can be achieved with local authorities only. 相似文献

Human capital depletion, human capital formation, and migration: a blessing or a “curse”? 总被引:1,自引:0,他引:1
We specify conditions under which a strictly positive probability of employment in a foreign country raises the level of human capital formed by optimizing workers in the home country. While some workers migrate, “taking along” more human capital than if they had migrated without factoring in the possibility of migration (a form of brain drain), other workers stay at home with more human capital than they would have formed in the absence of the possibility of migration (a form of brain gain). 相似文献

Options as a Marketing Tool: Pricing a Promotional Scheme for a Product with a Secondary Market

Adding options to durable products allows new opportunities for manufacturers and retailers in markets with a secondary market to create better segmentation schemes, provide creative means to differentiate their products and services, and increase the value they offer consumers. This raises the need for sellers to properly price such options. This work presents a few examples of incentive programs for the car industry, develops models and calculates their cost to the seller, demonstrating the applicability of the proposed methodology. Our numerical results indicate that such options are surprisingly inexpensive for car manufacturers and dealers. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

A larger portion of males is overweight than is females. Females' food choices in comparison to those of males reflect the greater importance that females attribute to health and physical appearance; their more complex attitude toward risk; the greater esteem in which they hold home-cooked food; and sociological factors. This paper explores the variables that affect consumers' food choices, shedding light specifically on the choice process and analyzing whether gender affects predispositions toward foods, perceptions, choice processes, or all three. Perceptions and choice processes based on memory judgments serve only as a benchmark used to compare choices consumers make under calorie information. The results of two experiments wherein the researchers exposed subjects to two forms of calorie information on three fast food items suggest that differences in perceptions of foods' healthfulness and taste aspects account for gender differences in memory-based choices. In addition to this baseline difference in perceptions, a gender difference in reaction to calorie information in terms of consumers' behavior exists. While calorie information affected both perceptions and choice processes for females, information changed the perceptions of food only for males. 相似文献
