Tax Policy and Human Capital Formation with Public Investment in Education

This paper studies the effects of distortionary taxes and public investment in an endogenous growth OLG model with knowledge transmission. Fiscal policy affects growth in two respects: first, work time reacts to variations of prospective tax rates and modifies knowledge formation; second, public spending enhances labour efficiency but also stimulates physical capital through increased savings. It is shown that Ramsey-optimal policies reduce savings due to high tax rates on young generations, and are not necessarily growth-improving with respect to a pure private system. Non-Ramsey policies that shift the burden on adults are always growth-improving due to crowding-in effects: the welfare of all generations is unambiguously higher with respect to a private system, and there generally exists a continuum of non-optimal tax rates under which long-run growth and welfare are higher than with the Ramsey-optimal policy.     

Effects of longevity and dependency rates on saving and growth: Evidence from a panel of cross countries

While earlier empirical studies found a negative saving effect of old-age dependency rates without considering longevity, recent studies have found that longevity has a positive effect on growth without considering old-age dependency rates. In this paper, we first justify the related yet independent roles of longevity and old-age dependency rates in determining saving and growth by using a growth model that encompasses both neoclassical and endogenous growth models as special cases. Using panel data from a recent World Bank data set, we then find that the longevity effect is positive and the dependency effect is negative in savings and investment regressions. The estimates indicate that the differences in the demographic variables across countries or over time can well explain the differences in aggregate savings rates. We also find that both population age structure and life expectancy are important contributing factors to growth.     

Does Gender have any Effect on Aggregate Saving? An empirical analysis

This study investigates the effects of gender on aggregate saving. We test the hypothesis that shifts in women's relative income, which can affect their bargaining power within the household, have a discernible impact on household saving and, by extension, gross domestic saving, due to differing saving propensities by gender. The empirical analysis is based on panel data for a set of semi-industrialised economies, covering the period 1975-95. The results indicate that, as some measures of women's relative income and bargaining power increase, gross domestic saving rates rise. The implied gender disparity in saving propensities may be linked to differences in saving motives based on gender roles, and well as divergent experiences of economic vulnerability. These findings suggest the importance of understanding gender differences in planning for savings mobilisation and in the formulation of financial and investment policies.     

The Welfare of Investment Deductibility Under a Flat Tax

This paper analyses the welfare effects of investment deductibility in a contest of endogenous growth generated by learning–by–doing and knowledge spillovers. We present a model where a set of revenue neutral fiscal policies, each characterized by different degrees of investment deductibility and different uniform tax rates on income, have been introduced. We show that, given the ratio of public expenditures to national product, partial investment deductibility turns out to be welfare enhancing when the intertemporal elasticity of substitution of consumption is sufficiently small. Our result means that a pure consumption tax—although ensuring more saving and faster growth—is not always preferable to a revenue neutral tax system in which both consumption and investment are taxed.     

Are saving and investment cointegrated? The case of Malaysia (1965–2003)

This article examines whether domestic saving rate leads to higher domestic investment rate in the case of Malaysia. We argue that the results obtained from cross-sectional studies are not able to address this issue satisfactorily and highlight the importance of individual country case studies. Using the recently developed autoregressive distributed lag bounds testing procedure, the results reveal a robust cointegrated relationship between domestic saving and investment rates during the period 1965 to 2003.     

Fiscal position and the financing of productive government expenditures: an application to Latin America

Government spending on public infrastructure, education, and health care can increase economic growth. However, the appropriate financing depends on a country’s fiscal position. We develop a two-sector endogenous growth model to explore how variations in the composition and financing of government expenditures affect economic growth. We find that, when tax rates are moderate, funding public investment by raising taxes may increase long-run growth. If existing tax rates are high, public investment is only growth enhancing if funded by restructuring the composition of overall public spending. Additionally, public investment that is debt financed can have adverse effects on long-run growth due to the resulting increases in interest rates and debt-servicing costs.     

Tax avoidance,human capital accumulation and economic growth

Human capital accumulation may negatively affect economic growth by increasing tax avoidance and reducing effective tax rates and productive public investment. This paper analyzes how the endogenous feedback between human capital accumulation and tax avoidance affects economic growth and macroeconomic dynamics. Our findings show that this interaction produces remarkable growth and welfare effects.     

Optimal fiscal policy in an endogenous growth model with public capital: a note

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.      

Capital income taxation,tax criteria,and intergenerational welfare

In a two-period overlapping-generations model, residence criteria are shown to be optimal with lump-sum transfers to the younger generation in a dynamically efficient open economy even if all wage income, corresponding to rent income under exogenous labor supply, is not taxed away. When tax revenues are also distributed to the older generation — which indeed may be desirable for short-term intergenerational welfare distribution reasons — a weighted average rule is derived for optimal international taxation. The taxation of domestic savings income follows the inverse elasticity rule in respect to savings and, surprisingly, higher investment elasticity increases the tax level. Finally, for a small open economy and for large identical economies, tax competition with a mixed scheme of residence-based taxes and source-based subsidies yields the same tax policy as tax cooperation with no restrictions on the domestic and international capital income tax instruments.     

TAXES AND GROWTH: TESTING THE NEOCLASSICAL AND ENDOGENOUS GROWTH MODELS

Changes in the tax rate alter real growth permanently in an endogenous growth model, but only temporarily in a neoclassical model, where the only permanent effect is a decrease in the steady-state level of output per capita. Using data from the 1960'1992 period for a panel of 11 Organization of Economic Cooperation and Development economies, this paper's empirical results support the following conclusions. First, consistent with the tax smoothing hypothesis, tax rates have exhibited significant persistent changes while output growth rates have not. Second, a higher tax rate permanently reduces the level of output but has no permanent effects on the output growth rate. These findings are inconsistent with endogenous growth mechanisms and suggest that the relationship between output and the tax rate is best described by the neoclassical growth model.

Has the capital accumulation in the Asian miracle economies been fuelled by growth?

The Asian growth miracle is often attributed to factor accumulation under the implicit assumption that savings, broadly defined, have been high and increasing due to exogenous forces. Using data for India, Indonesia, Korea, Singapore and Taiwan over the period 1870–2011 this article examines the causal relationship between growth and saving. The response of growth to savings is first estimated using instruments to generate exogenous variation in savings rates. The residual variation in growth that is not driven by savings is then used as an instrument to estimate the effect of growth on savings. The estimates show that the spectacular saving rates in the Asian miracle economies have been fuelled by growth, and not the other way around.     

Terrorism,openness and the Feldstein–Horioka paradox

This paper investigates how terror threats and international openness affect the savings retention coefficient in the Feldstein–Horioka equation. We find that terrorism marginally increases the size of this coefficient, which may result from an increase in the precautionary saving motives. However, even a small increase in openness offsets this effect and significantly lowers the propensity to retain domestic savings for investment. This suggests that, given more channels, capital leaves domestic boundaries to land in safe places abroad. At least partly, the results explain the paradoxical finding in the literature that capital is more mobile in developing countries, even though they are less open. We also find that all types of terrorism reduce investment.     

Testing the validity of the Feldstein–Horioka puzzle for Australia

This article presents the details of an investigation into the relationship between investment and savings in Australia over the period 1960 to 2007. Using five time series techniques our results reveal that the Feldstein–Horioka puzzle exists in a weak form, with a lower saving retention coefficient. Granger causality tests illustrate that savings Granger causes investment, both in the short and long runs. Our results suggest Australia could effectively adopt policies that focus on increasing investment through increasing domestic savings.     

Worker remittances,migration, accumulation and growth in poor developing countries: Survey and analysis of direct and indirect effects

A broad but brief survey of the literature on remittances and growth shows that indirect effects are only included via interaction terms. Then, we regress data for migration, worker remittances, savings, investment, tax revenues, public expenditure on education, interest rates, literacy, labor force growth, development aid and GDP per capita growth on migration, remittances and other variables for a panel of countries with income below $1200. The estimated dynamic equations are integrated to a system used for baseline simulations. Comparison with the counterfactual policy simulations ‘only 50% remittances’ or ‘no net migration anymore’ shows that the total effect of remittances on levels and growth rates of GDP per capita, investment and literacy are positive, and that of net migration is negative for literacy and investment but positive for growth.     

Economic Growth with Foreign Capital

In growth theory, foreign investment places a small open economy in the international steady state. In applied growth theory, foreign investment is assumed to shift technology. The present growth model separates foreign from domestic capital and develops the steady state where both capital/labor ratios are stationary. A capital scarce country would attract foreign investment and may arrive at a steady state with perpetual foreign investment. Such a steady state foreign investment host is characterized by low saving and high labor growth rates, and source countries the opposite. Incomplete convergence characterizes economic growth with foreign capital.     

Fiscal Policy and Equitable Growth

This paper continues the study of optimal fiscal policy in a growing economy by exploring a case in which the government simultaneously provides three main categories of expenditures with distortionary tax finance: public production services, public consumption services, and state-contingent redistributive transfers. The paper shows that in a general-equilibrium model with given exogenous fiscal policy, a nonmonotonic relation exists between the suboptimal long-run growth rate in a competitive economy and distortionary tax rates. When fiscal policy is endogenously chosen at a social optimum, the relation between the rate of growth and tax rates is always negative. These two properties suggest that an alternative set of government policy instruments affects the response of private sector investment to fiscal policy. Moreover, the different properties of exogenous and endogenous fiscal policy theoretically account for the difference in the relation between economic growth and fiscal policy in empirical studies.     

Patience and prosperity

This paper introduces wealth-dependent time preference into a simple model of endogenous growth. The model generates adjustment dynamics in line with the historical facts on savings and economic growth in Europe from the High Middle Ages to today. Along a virtuous cycle of development more wealth leads to more patience, which leads to more savings and further increasing wealth. Savings rates and income growth rates are thus jointly increasing during the process of development until they converge towards constants along a balanced growth path. During the transition to modern growth an economy in which the association of wealth and patience is stronger overtakes an otherwise identical economy and generates temporarily diverging growth rates.     

Demographic links to savings in life cycle models: identification of issues for LDCs

The author considers the potential for a link between the recent pattern of demographic transition and intertemporal and inter-country variations in savings rates. Fertility, infant mortality, life expectancy, and levels of female and child labor force participation are among the various demographic factors which affect national savings rates through their effects upon age structure, age-specific individual savings behavior, and their general equilibrium effects upon interest rates, wage rates, and income distribution. The author establishes a simple discrete time life cycle model of savings, explains the issues related to age structure, and discusses the effect of age-specific savings functions, the general equilibrium effects of demographic factors, the effects of life expectancies and child mortalities, and the nature of social security coverages in less developed countries, as well as issues which are especially important for less developed countries. A new strategy for empirically evaluating demographic policies is proposed. That is, one can estimate the age profile of earnings, saving and fertility rates from household survey data. The life tables can then be used to compute the aggregate savings rate and population size. Any demographic policy which affects the fertility rate, life expectancy, and investment in the quality of children will change the aggregate saving and population growth rates. These two aggregate effects could be compared to evaluate demographic policies. The author stresses, however, that changes in different demographic factors will have different short-run and long-run effects upon the savings rate which will also depend upon whether such changes are transitory or permanent.     

Employment- and growth effects of tax reforms

Since the mid-1990s almost all OECD countries have engaged in fundamental reforms of their tax systems. There is a trend towards higher social security contributions and lower tax rates on personal and corporate income. This paper explores whether these tax policy measures are effective means for reducing unemployment and accelerating economic growth. Using a Pissarides type search model with endogenous growth, we analyze how savings and the incentive to create new jobs are affected by revenue-neutral tax swaps between wage income taxes, payroll taxes, capital income taxes and taxes levied on capital costs. In our framework, cutting the capital income tax (reducing the double taxation of dividend income) financed by a higher payroll tax turns out to be superior, such a policy mix fosters both employment and growth. Most other tax reforms imply a trade-off between employment and growth.     

Capital formation and demographics

Low rates of saving and capital formation have been a disturbing and persistent characteristic of the United States' economy. The leading explanation of this phenomenon is based on the effects of inflation under our nonindexed tax system—a financial explanation. This paper explores, with a simple life-cycle savings model with irreversible capital, whether a real explanation exists. The analysis indicates that plausible prospective declines in the growth rate of the working-age population can lower the equilibrium interest rate and the rates of saving and capital formation in spite of a relatively high marginal product of capital. The policy implications of the real explanation are also discussed.
