This paper examines the relationship between wealth distribution and economic growth in an endogenous growth model with heterogeneous households and redistributive taxation. In this paper, we incorporate an endogenous determination of redistributive policy into the model, focusing on the relation between pre- and post-tax inequality. Endogenous redistributive policy affects wealth distribution and economic growth. Therefore, the relation between post-tax inequality and economic growth is different from that between pre-tax inequality and economic growth. Results show that there exists a negative correlation between pre-tax inequality and economic growth, whereas there exists an inverted-U relationship between post-tax inequality and economic growth in a voting equilibrium. 相似文献

This paper presents development of an endogenously growing finite horizons model with public capital, and investigates macroeconomic effects of fiscal policy and a change in life expectancy. Specifically regarding novel results, a growth‐maximizing income tax rate exists that is less than the elasticity of public capital to output. In addition, in the model with income tax financing, there might exist an inverted‐U‐shaped relationship between life expectancy and growth, which is consistent with some empirical evidence. In this paper, we elucidate the interaction among public capital accumulation, taxes, growth, welfare and life expectancy. 相似文献

Who gains from capital market integration? Tax competition between unionized and non‐unionized countries 下载免费PDF全文
The welfare effects of capital market integration are examined under a model of tax competition with two asymmetric countries. The asymmetry is expressed through the labour market: one country has a perfect labour market whereas the other country's labour market is unionized. Our results indicate that the welfare effects of capital market integration differ depending on whether governments are active or passive in attracting capital. In the absence of active governments, capital market integration benefits the country with a competitive labour market whereas it harms the unionized country. Capital market integration benefits both countries if governments are active and compete for mobile capital using taxes/subsidies. 相似文献

This note presents an investigation of the optimal tax rule in endogenous growth models with public capital. It is presumed
that the government levies only an income tax in addition to financing public investment. Furthermore, a household’s saving
is deducted from the income tax. We find the optimal tax rule whereby the social optimum is attainable. The manner by which
a government imposes a tax on income and administers tax deductions is important for attaining a socially optimal situation.

We study how the quality of hospital management and medical care both affect efficiency in Japanese local public hospitals. The efficiency is estimated by a stochastic frontier analysis (SFA) and is regressed against the quality scores in hospital accreditation by the Japan Council for Quality Health Care (JCQHC). We find that rule-based hospital management relates to high efficiency, while the suitable management of beds and supplies relates to low efficiency. 相似文献

Variety of products,public capital,and endogenous growth 总被引:1,自引:0,他引:1
This paper develops an extension of the endogenous growth model with variety expansion presented in Romer [Romer, P.M., 1990. Endogenous technical change, Journal of Political Economy 98, part 2, S71–S102] by considering public capital accumulation. Characterizing the transitional dynamics, the growth rate of consumption traces (and available number of intermediate goods also might trace) an S-shaped converging path to the equilibrium growth rate, similar to a logistic growth curve, if the intensity of public capital is sufficiently high. We also show that public investment enhances economic growth because it stimulates demand for intermediate goods and raises the market interest rate. 相似文献

This paper presents an extension of a static model of public goods provision with redistributional taxation, as described by Uler [Journal of Public Economics 93 (3–4), pp. 440–453], as a dynamic model of wealth accumulation. Intertemporal consumption and saving behavior strongly affect the relation between redistributive taxation and charitable contribution. Indeed, the analyses presented herein reveal that more patience (i.e. higher saving) engenders a lower redistributional tax rate. However, the optimal redistributive tax rate is not zero because redistributive taxation improves the efficiency of providing public goods that are not improved by balanced growth. This paper fills the gap separating static analysis and dynamic analysis, and generalizes the results presented by static analysis. 相似文献

In this paper, we consider the problem of an optimal pension fund portfolio given the heterogeneous risk preferences of pension fund participants. The relative risk aversion of a pension fund tends to be a decreasing function of the level of aggregate wealth. We find that the dynamic optimal portfolio is simply characterized as the weighted sum of the optimal portfolio for each participant. Our model helps successfully establish the microfoundation of asset liability management models. A numerical example using recent Japanese data indicates the significant total welfare losses of adopting a suboptimal portfolio strategy and an inefficient risk‐sharing rule. 相似文献
