At a theoretical level this article discusses Piketty’s hypothesis that the distribution of income and wealth tends to become more concentrated over time when the rate of return on capital is greater than the growth rate of real output. We develop a post Keynesian model of growth and distribution showing that once capital is differentiated from wealth, the increase in income and wealth concentration actually occurs when the rate of valorization of financial and real estate assets is greater than the growth rate of real output, and that this situation may be triggered by financial liberalization. 相似文献

We introduce an external effect of existing technologies in human capital accumulation in an endogenous growth model and describe its steady-state and transition. We numerically solve the model to compare the quantitative effects of R&D policy with the quantitative effects of human capital policy in wealth and welfare. Although R&D subsidies have now an overall positive effect on growth, wealth and welfare, the calibration exercise shows that for plausible values for the parameters, human capital policy is simultaneously the most income and welfare-improving and the less expensive to the government. 相似文献

We present an endogenous growth model in which households display their social status by holding not only capital but also bonds. According to conventional wisdom, the quest for social status provides an incentive for individuals to accumulate wealth, which stimulates economic growth and elevates it to a socially optimal level. Instead, we show that portfolio allocation is crucial to the growth-enhancing effect of the quest for social status. If households exhibit their social status by accumulating physical capital and holding government bonds, the quest for social status may not increase economic growth. As a result, social status seeking cannot achieve the social optimum. Calibrating our model to data, we find that if government bonds constitute part of the wealth for households’ quest for social status, the quest for social status decreases economic growth. 相似文献

Right-skewed and thick-tailed wealth distributions have been documented as an empirical regularity across space and time. A key mechanism for explaining these distributional features is proportional random growth. We investigate the comparative statics of a well-defined class of random growth models when allowing for stochastically ordered shifts in the wealth return process. An order-contingent monotone comparative statics property is identified, according to which pure increases in risk (e.g. higher volatility of capital returns) foster top wealth concentration whereas first-order stochastically dominated shifts in the return process (induced by e.g. proportional capital income taxation) rather lower inequality at the upper end of the distribution. Our analysis points to the potentially ambiguous effects on top wealth inequality of introducing or modifying capital income tax treatments in the presence of stochastic returns. 相似文献

Abstract This paper analyzes the burden of debt in a growth model that combines overlapping generations of workers who save for life-cycle reasons and dynastic agents who save for bequest reasons (‘capitalists’). Ricardian Equivalence prevails, but capitalists regard the debt serviced out of taxes on workers as net wealth. In the long run, the Cambridge Theorem holds: the relationship between the rate of profit and rate of growth is determined by the capitalist saving function, independently of worker or government saving. Two alternative closures are considered. Under exogenous growth constrained by a fully employed labor force, debt and deficits result in temporary effects on the distribution of income but permanent effects on the distribution of wealth. Under endogenous growth constrained by a fully utilized capital stock, debt and deficits result in temporary effects on the growth rates of the components of wealth and permanent effects on the level and distribution of capital. 相似文献

This paper proposes a simple two-country endogenous growth model with endogenous consumption, leisure time and wealth accumulation. The model examines possible causes for the world economic growth and the existence and persistence of trade patterns between countries with different preferceces and human capital under internationally free capital mobility. We show how differences in preferences in consumption, leisure time and wealth between the two countries may affect long-run world economic growth. 相似文献

This paper analyzes endogenous fiscal policy in an endogenous growth model where agents care about social status and environmental quality. The quest for a higher status is assimilated to a preference for capital wealth. The government uses income tax to finance infrastructure and environmental protection. We find that accounting for preferences for social status and environmental quality may lead to an allocation of tax revenue in favor of a cleanup effort to the detriment of infrastructure. Economic growth is not necessarily and negatively affected by this allocation as it is partly explained by an excessive accumulation of capital wealth due to the quest of status. Status seeking can however harm economic growth and environmental quality when its motive is important enough. Finally, we show that economic growth may be consistent with environmental preservation but is not necessarily welfare-improving as in the case of absence of status-seeking behavior. 相似文献

Following the approach of Corrado, Hulten, and Sichel (2005, 2006 ), we measure intangible investment and examine the contribution of intangible capital to economic growth in Japan. We find that the ratio of intangible investment to GDP in Japan has risen during the past 20 years and now stands at 11.1 percent, which is lower than the ratio estimated for the U.S. in the early 2000s. The ratio of intangible to tangible investment in Japan is also lower than equivalent values estimated for the U.S. In addition, we find that, in stark contrast to the U.S., where intangible capital grew rapidly in the late 1990s, the growth rate of intangible capital in Japan declined from the late 1980s to the early 2000s. Our conclusions regarding intangible investment in Japan remain largely unchanged even if, using data with respect to firm-specific resources, we take on-the-job training into account. 相似文献

We develop an endogenous growth model in which individuals form matches in order to consume goods that are not explicitly traded. The matching process endogenously generates a concern for relative wealth and is thereby beneficial for capital accumulation and economic growth. We then study how social segmentation in the matching process affects economic growth. Under strong segmentation, social competition over mates occurs inside homogeneous groups. This homogeneity increases the severity of the "rat race" of wealth accumulation and fosters economic growth. 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

The Division of Labor, Inequality and Growth 总被引:6,自引:0,他引:6
We present a model that links the division of labor and economic growth with the division of wealth in society. When capital market imperfections restrict the access of poor households to capital, the division of wealth affects individual incentives to invest in specialization. In turn, the division of labor determines the dynamics of the wealth distribution. A highly concentrated distribution of wealth leads to a low degree of specialization, low productivity, and low wages. In that case workers are unable to accumulate enough wealth to invest in specialization. Hence, in a highly unequal society, there is a vicious cycle in which the degree of specialization, productivity and wages stay low, wealth and income inequality stays high and the economy stagnates. By contrast, greater equality increases investment in specialization and leads to a greater division of labor and higher long run development. 相似文献

This paper analyses the equilibrium distribution of wealth in an economy where firms’ productivities are subject to idiosyncratic shocks, returns on factors are determined in competitive markets, households have linear consumption functions and government imposes taxes on capital and labour incomes and equally redistributes the collected resources to households. The equilibrium distribution of wealth is explicitly calculated and its shape crucially depends on market incompleteness. With incomplete markets it follows a Paretian law in the top tail and the Pareto exponent depends on the saving rate, on the net return on capital, on the growth rate of population, and on portfolio diversification. The characteristics of the labour market crucially affects the bottom tail, but not the upper tail of the distribution of wealth in the case of completely decentralized labour market. The analysis also suggests a positive relationship between growth and wealth inequality. The theoretical predictions find a corroboration in the empirical evidence of United States in the period 1989-2004. 相似文献

An optimal redistributive tax-subsidy formula is derived for a growth model where income inequality is endogenously driven by an adult's choice of occupation between work and management. Investment in human capital is the engine of growth. The world's stock of exploitable knowledge as well as the economy's average human capital determine the potential rate of return from investment in human capital in an economy. How much available knowledge would be exploited in the economy depends on the proportion of innovators in our model. A redistributive tax reform impacts growth as well as income inequality via its influence over the occupational choice. The optimal redistributive tax rate is path-dependent in the sense that it depends on the initial wealth distribution. The normative implication of the model is that the optimal capital income tax rate could very well be positive if the initial wealth inequality exceeds a threshold. The optimal capital income tax rate depends inversely on the initial wealth inequality. 相似文献

The paper contributes to the literature relating to inequality and economic growth, in particular, we investigate the effects of wealth distribution on the kind of growth driven by innovation, i.e. Schumpeterian growth. Since two types of individuals are assumed, the poor and the rich, Gini-coefficient is treated in two variables, namely the relative wealth of the poor and the population share of the poor, each having a different effect on economic performance. Particularly in the separating equilibrium, an improvement in the relative wealth of the poor impedes economic growth, but a decline in the population share of the poor enhances economic growth. Furthermore, the current paper combines the Schumpeterian quality improvement model and the neoclassic production function. Thus, the impact of wealth inequality on economic growth is through the supply of human capital as well as the demand for better quality goods. Our results suggest that empirical research on the base of Gini-coefficient cannot generate a general relationship between wealth inequality and economic growth. 相似文献

Information Technology and Productivity Growth in the 2000s 总被引:3,自引:0,他引:3
Abstract. US productivity growth experienced continued productivity growth after 2000 even as investment, particularly in information technology (IT), slowed. This paper uses industry-level data to examine the link between average labor productivity (ALP) growth and IT in the post-2000 period. We use difference-in-difference and cross-sectional regressions to show that the link between ALP growth and IT-intensity is weaker after 2000 than before. These results are robust to alternative measures of IT-intensity such as the IT share of capital services, the level of IT capital depth, and the share of IT capital services in total output. We conclude that the post-2000 productivity gains in the United States do not appear to have been driven directly by IT. 相似文献

This paper explores the impact of credit market imperfection on lack of demand for capital, trade, and capital flows in an economy with wealth heterogeneity. In particular, we look at the implications of wealth heterogeneity. We show that the low return of capital and lower output of credit-intensive output in autarky may reflect lack of entrepreneurship and demand for credit due to wealth heterogeneity and eventually may lead to capital outflow from a capital-scarce country. This is a different way of echoing the sentiment of the well–known Lucas paradox, which suggests that capital might flow from the poor to the rich countries. We also show the possibility of trade and capital flow being complements and not substitutes, as is usual in standard trade models driven by factor abundance. 相似文献

We analyze the interdependence between green attitude and equilibrium development of environmental quality in an endogenous growth model. Individuals take only part of their impact on pollution into account, hence there is a negative externality of capital accumulation on environmental quality. Increasing wealth or increasing pollution enhance green attitude and reduce the externality, because individuals care more about the environment if their income is higher or if pollution is more obvious. The time path of pollution as well as the evolution of equilibrium growth are shown to depend crucially on the determinants of green attitude. Ongoing growth may lead to complete internalization of the environmental externality if green attitude improves with increasing wealth, e.g. as a consequence of an increase in environmental education. In contrast, if green attitude is determined exclusively by the level of environmental quality, pollution remains at a suboptimally high level. The interdependence of wealth and pollution in the determination of environmental awareness implies more complex dynamics. Capital growth enhances green attitude and thereby decreases pollution. Improved environmental quality in turn may increase capital growth due to less green attitude and therefore slow down convergence to the sustainable balanced growth path. 相似文献

We provide a new data set on per capita book production as a proxy for advanced literacy skills, and assess this relative
to other measures. While literacy proxies very basic skills, book production per capita is an indicator for more advanced
capabilities. Growth theory suggests that human capital formation plays a significant role in creating the ‘wealth of nations.’
This study tests whether human capital formation has an impact on early-modern growth disparities. In contrast to some previous
studies which denied the role of human capital as a crucial determinant of long-term growth, we confirm its importance.
