In this paper, we investigate the effect of a corporate income tax on the utilization and maintenance of capital and on the demand for capital stock and services. We find that a tax that allows interest deductions is distortionary unless allowable depreciation depends on the firm's utilization and maintenance decisions. Also, we show that the usual demand equation for capital stock is misspecified if capital utilization is not a technological constant. 相似文献

We study human capital accumulation in the presence of labor search frictions. Given that unemployed workers can default on their education loans, skilled individuals with a larger debt burden prefer riskier but better paid careers than is socially desirable. A higher level of employment risk in turn depresses the skill premium and the incentives to invest in education. The equilibrium allocation is characterized by too low employment, underinvestment by the poor, and too little investment in skill-intensive technologies. A public education system funded by graduate taxes can restore efficiency, and it would also reduce wage inequality. 相似文献

This paper provides an overview of the interaction between social security and retirement behavior in Austria in the decades up to the on-going reform process. The key question is, how much of the retirement behavior can be attributed to incentive effects of the pension system. We describe the labor market and retirement behavior of the elderly in Austria, survey the key features of the public pension system and finally present the results of a series of simulations aimed at assessing the retirement incentives generated by the pension system. We compute levels and accrual rates of social security wealth and implicit tax rates on continued work according to the method portrayed in Gruber and Wise [Gruber J, Wise D (1999) Social security and retirement around the world. University of Chicago Press, Chicago London]. To some extent, the sharp drop in labor force participation among the elderly must be attributed to major disincentives of the Austrian pension system; the system turns out to provide significant incentives to retire early. Past reforms have reduced the disincentives. Our results, however, show the need to further reform the public pension scheme and to reorient it stronger towards the principle of actuarial fairness. 相似文献

In this paper, capital market imperfections are endogenized considering an adverse selection problem between banks and borrowers. We develop a growth model with linear OLG wealth dynamics, where agents are heterogeneous in terms of observable wealth and ability, which is private information. We show that banks react to this informational asymmetry by granting higher loans to talented borrowers. This, in turn, helps poor and talented agents to become educated and catch up with the rich agents. Furthermore, the credit market friction leads to greater human capital accumulation. 相似文献

资源安全与我国的境外投资促进政策 总被引:1,自引:0,他引:1
近年来,我国境外投资活动发展迅速,境外投资政策的体系也正在由限制走向中性的政策体系。境外投资支持体系主要围绕如下四个的功能而设计,分别是投资保护、监管、服务与引导,同时也需要对某些产业的境外投资给予特殊的支持。境外投资政策体系的结构及其基础1.鼓励与限制相结合的中性原则如何正确地看待企业的境外投资行为,是政府制订政策时首先需要解决的问题。经济学原理认为,资本的跨国界流动可以改善资源配置的效率,从而增进世界福利水平。以此为依据,可以认为允许资本自由流动是符合经济理想的。但这一原理是以一系列严格假定为前提的,… 相似文献

This paper examines the choice of international factor mobility. It proves in a two-country, two-factor, one-commodity model that the policy-setter, when it maximizes its own welfare by following the Ramaswami policy of monopsonistic import of its scarce factor, impoverishes the passive country. Furthermore, the paper studies the choice of mobility in a two-commodity model and shows that the optimality of the monopsonistic import policy extends to a situation with trade in goods. Lastly, it addresses the welfare effects in the passive country in the two-commodity model. 相似文献

This paper empirically identifies social learning and neighborhood effects in schooling investments in a new technology regime. Social learning implies that learning is most efficient when observed heterogeneity in schooling is greatest. The estimates of learning-investment rule, from farm household panel data at the onset of the Green Revolution in India, show that (i) agents learn about schooling returns from income realizations of their neighbors, and (ii) the speed of learning is high when the variation of schooling is large. Thus, schooling distribution of the parents' generation in a community has externalities to schooling investments in children. Simulations show that the variations in schooling within and across communities generate variations in child enrollment rate and average household income. 相似文献

This paper investigates the relationship between international migration, remittances, and human capital investment in Kenya. We use household‐level data from the 2009 Kenya Migration Household Survey (which was part of the Africa Migration Project) to test our hypothesis and uncover a positive and significant relationship between the amount of international remittances a household receives and the amount of expenditures allocated to education (for all levels of education). We consider various robustness checks and find that our results hold up to various specifications, including an instrumental variable approach. 相似文献

Life expectancy, human capital, social security and growth 总被引:3,自引:0,他引:3
We analyze the effects of changes in the mortality rate upon life expectancy, education, retirement age, human capital and growth in the presence of social security. We build a vintage growth, overlapping generations model in which individuals choose the length of education and the age of retirement, and where unfunded social security pensions depend on workers' past contributions. Social security has a positive effect on education, but pension benefits favor reductions in retirement age. The net effect is that starting from a benchmark case, higher life expectancies give rise to lower per capita GDP growth in the presence of social security as the share of the active population is reduced. In addition, higher social security contribution rates reduce the growth rate of per capita GDP. 相似文献

教化投资:人力资本投资的新形式 总被引:2,自引:1,他引:2
本文针对现有的人力资本理论将人力资本投资形式局限于教育、培训、医疗、保健和迁移,而对其他投资形式关注不足的现实,认为适应于现代经济生活相关的思想观念、价值取向和道德规范,需要相关投入才会形成,这些投入也是人力资本投资不可或缺的形式,笔者将其概括为教化投资。经济转型过程凸显了教化投资的重要性。教化投资增强了人力资本的资源配置能力,在扩大个体人力资本存量的同时,还提升了社会经济价值,增加了社会资本。 相似文献

This study attempts to reassess the evidence on the degree of capital mobility and crowding out by applying a varying coefficients model to data on 19 OECD countries over the 1971–1999 period. Our period-specific results strongly support the crowding-out effect as well as the low capital mobility argument for this group of countries as a whole. However, the strength of the crowding-out effect appears to weaken and the degree of capital mobility to increase in the 1990s as compared to the 1970s and 1980s. We also classify countries into five groups according to the relative size of the government sector. Our group-specific results indicate that the degree of capital mobility is generally lower and the crowding-out effect generally stronger, in country groups with smaller governments. The differences are especially evident when we compare the group with largest government size with all other groups, those differences between the latter being much more modest. However, significant differences in the country-specific results suggest that it is prudent to be cautious when we draw conclusions about crowding-out and capital mobility for specific countries from the period-wise or group-wise results. This is particularly important in drawing policy implications for specific countries. 相似文献

This paper incorporates the concept of real option into a modified Harris–Todaro model to investigate the relationship between higher education and unemployment rates. We found that the real option value of waiting to invest in graduate school education will decrease when the expected wage rate of labors with an undergraduate degree becomes relatively lower than that with a graduate degree. As a result, more undergraduate students will decide to go to graduate schools immediately after graduation. As the supply of labors with a graduate degree increases and the job creations fail to meet the increasing demand, those who cannot get a graduate-level job will be willing to accept job offers lower than their education level. Our modified Harris–Todaro model shows that it will lead to an increase in the number of unemployed and underemployed higher educated labors. This explains why the unemployment rates for higher educated labor are relatively high in some developed countries. 相似文献

Disclosure by firms would seem to reduce investment inefficiency by reducing informational asymmetry. However, the impact of disclosure is endogenous and depends on incentives within the firm. Given optimal renegotiation-proof contracts, disclosing only accepted contracts does not solve the Myers-Majluf problem. What solves the problem is having either full transparency of all compensation negotiations or, more reasonably, additional forward-looking announcements. The model is robust to renegotiation in equilibrium, the order of moves, and moral hazard. The analysis illuminates disclosure regulation: forward-looking disclosure is beneficial when the manager's contract is optimal and induces truth-telling. 相似文献

This paper analyzes how population and product market competition (PMC) may interact with each other in affecting the pace of economic growth. The impact of a change in population (size or growth) and in the degree of PMC on productivity growth may vary depending on the presence of human versus physical capital investment, the way in which individuals may purposefully invest in human capital, the type of input used in the uncompetitive sector, the form of households’ intertemporal utility, and whether PMC (measured by the degree of substitutability between differentiated intermediates) is disentangled or not from the input shares in aggregate income. It is found that a growth model with human capital accumulation à la Lucas (J Monet Econ 22(1):3–42, 1988) and a continuum of degrees of intertemporal altruism can predict an ambiguous link between population and economic growth rates, in line with the available empirical evidence. The article also analyzes the conditions under which market structure (monopoly power) and population (size or growth) may be complementary to each other in the process of long-run economic growth. 相似文献

Platform competition and seller investment incentives 总被引:1,自引:0,他引:1
Many products and services are not sold on open platforms but on competing for-profit platforms, which charge buyers and sellers for access. What is the effect of for-profit intermediation on seller investment incentives? Since for-profit intermediaries reduce the available rents in the market, one might naively suspect that sellers have weaker investment incentives with competing for-profit platforms. However, we show that for-profit intermediation may lead to overinvestment when free access would lead to underinvestment because investment decisions affect the strength of indirect network effects and, thus, access prices. We characterize the effect of for-profit intermediation on investment incentives depending on the nature of the investment and on which side of the market singlehomes. 相似文献
