Consumption tax and economic growth in an overlapping generations model with money holdings

This paper examines the effect of a consumption tax on economic growth using an overlapping generations (OLG) model with money holdings. We show that the neutrality of the consumption tax does not hold in the money-in-the-utility-function model, because a change in consumption taxation induces the substitution of money holdings for consumption, and the money is the net wealth within the OLG structure. An increase in the consumption tax rate lowers (raises) the growth rate under a low (high) monetary expansion rate. On the other hand, in the cash-in-advance model and the money-in-the-production-function model, the neutrality of consumption taxation holds even within the OLG structure, because in these models there is no substitution of consumption and money holdings.     

The Optimal Inflation Tax

We determine the second best rule for the inflation tax in monetary general equilibrium models where money is dominated in rate of return. The results in the literature are ambiguous and inconsistent across different monetary environments. We derive and compare the optimal inflation tax solutions across the different environments and find that Friedman's policy recommendation of a zero nominal interest rate is the right one.Journal of Economic LiteratureClassification Numbers: E31, E41, E58, E62.     

The Effects of Macroeconomic Policies in a Mercantilist Economy

By introducing money and foreign exchange in the Zou (1997) model of mercantilism, the paper shows the effects of macroeconomic policies in mercantilist economies. It is shown that in the long run, consumption and foreign asset accumulation increases as a result of stronger mercantilist sentiments, permanent increases in the consumption tax, increases in the monetary growth rate and purchases of foreign bonds. In the short run, however, macroeconomic disturbances including the mercantilist sentiments, the monetary growth rate, and the consumption tax have negative effects on current consumption and positive effects on current foreign asset accumulation, while purchasing foreign bonds has positive effects on both current consumption and current foreign asset accumulation. The theoretical explorations may provide a theoretical structure for hoarding international reserves and export-led growth strategy utilized by emerging market economies.     

Anticipated Inflation, Liquidity Costs and the Tobin Effect

This paper analyses the steady-state effects of inflation on capital accumulation within an optimizing monetary growth model with liquidity costs and an endogenous labour supply. It is assumed that consumption and leisure are perfect complements in the preferences of the representative agent. The particular environment considered, despite the results obtained by the growing literature on inflation and growth with endogenous labour effort, gives support to the Tobin effect, i.e. a positive effect of the money growth rate on capital, labour and output.

Some Fiscal Implications of Monetary Policy

We study the implications of alternative monetary targeting procedures for real interest rates and economic activity. We find that countercyclical monetary policy rules lead to higher real interest rates, higher average tax rates, lower output but lower variability of tax rates and consumption relative to procyclical rules. For a country with a high level of public debt (e.g. Italy), the adoption of a countercyclical procedure such as interest rate pegging may conceivably raise public debt servicing costs by more than half a percentage point of GNP. Our analysis suggests that the current debate on the targeting procedures of the European Central Bank ought to be broadened to include a discussion of the fiscal implications of monetary policy.     

Relative Wealth, Consumption Taxation, and Economic Growth

This paper examines the role of the relative wealth-induced status motive in affecting the neutrality of consumption taxation in an optimizing growth model. It is found that a key factor determining the validity of the neutrality of consumption taxation in both the level sense and the growth rate sense is the desire for relative wealth-induced social status. When individuals care about their relative wealth, a rise in consumption tax enhances the steady-state level of capital stock and consumption. Furthermore, if the production function takes a linear technology form as the engine of sustained growth, then increases in consumption taxation raise the economy's long-run growth rate. In addition, an optimal consumption tax policy provides full subsidies to consumption so as to induce the economy to achieve the social optimum and the optimal growth rate.     

Inflationary finance, capital mobility, and monetary coordination

This paper compares the inflation rate before and after monetary coordination between two benevolent governments. Many authors have previously argued that monetary coordination will reduce inflation [e.g., Aizenman, 1992; Beetsma & Bovenberg, 1998; Jensen, 1997; Kimbrough, 1993; Sibert, 1992; Tori, 1997]. Unlike these studies, the present paper introduces a mobile factor, which is capital. While capital may move freely between countries, it is subject to the inflation tax of the country in which it is located. This is because of a cash-in-advance type constraint governing investment expenditures. Since capital is perfectly mobile, inflation tax competition between governments leads to suboptimally low inflation. When countries coordinate their monetary policies, they can raise the inflation tax simultaneously without fear of capital flight. Hence, inflation tends to increase rather than decrease after monetary coordination.     

Is the Sky the Limit? Can Japanese Government Bonds Continue to Defy Gravity?

This paper presents a simulation model based on the growth rate, the inflation rate, and the consumption tax rate in the future. Future tax revenues and fiscal expenditures are projected using regression models estimated from past data. The fiscal situation is called unsustainable if the outstanding amount of Japanese government bonds (JGBs) becomes higher than the level of private sector financial assets. We focus on the general account of the central government, which is the source of JGB issues. We find that the higher the economic growth, the more likely it is that the fiscal situation is sustainable. When a larger portion of interest income is reinvested in JGBs, the chance is higher that the fiscal situation is sustainable. Most importantly, raising the consumption tax to 20% guarantees fiscal sustainability in most cases. Our analysis shows that without a consumption tax hike beyond the 10% rate, a fiscal crisis will be almost a certainty, even with a real economic growth rate of 2% despite a shrinking labor force. A reasonably quick hike of the consumption tax, namely a hike by 1% a year, up to 20%, combined with high or moderate economic growth rates, seems to keep the economy out of a fiscal crisis, where a moderate growth rate is defined to be generated by a productivity increase per working‐age population of 1.9%, which was the average during the Koizumi years.     

Monetary policy,endogenous transactions,and financial market segmentation

An endogenous financial market segmentation model is constructed to explore the role of costly credit as a medium of exchange in the monetary policy elasticity of financial market activity. Against inflation risk, credit is an alternative insurance device to a cash transfer from the financial market. In equilibrium, credit reduces the financial market activity rate. Monetary policy has redistributive effects across economic individuals. Inflation may not tax financial market non-participants. However, it may tax financial market participants by increasing the financial market activity rate. Welfare may increase and the optimal money growth rate can be positive.     

Effluent taxes,market structure,and the rate and direction of endogenous technological change

This paper studies the effects of effluent taxes on firms’ allocation of resources to cost-reducing and emission-reducing R&D, and on entrepreneurs’ decisions to develop new goods and enter the market. A tax set at an exogenous rate that does not depend on the state of technology reduces growth, the level of consumption of each good, and raises the number of firms. The induced increase in the variety of goods is a benefit not considered in previous analyses. In terms of environmental benefits, the tax induces a positive rate of pollution abatement that offsets the “dirty” side of economic growth. A tax set at an endogenous rate that holds constant the tax burden per unit of output, in contrast, has ambiguous effects on growth, the scale of activity of each firm and the number of firms. Besides being novel, the potential positive growth effect of this type of effluent tax is precisely what makes this instrument effective for welfare-maximizing purposes. The socially optimal policy, in fact, requires the tax burden per unit of output to equal the marginal rate of substitution between the growth rate of consumption and abatement. Moreover, a tax/subsidy on entry is needed, depending on whether the contribution of product variety to pollution dominates consumers’ love of variety.      

Taxation, Human Capital Accumulation and Economic Growth

Previous studies have shown that tax rates and the growth rate of output are negatively related under the assumption that government wastes tax revenues. This paper shows that, if tax revenues are used for human capital accumulation, tax rates and the growth rate can be positively related. An increase in the human capital tax rate will increase (decrease) the growth rate when the initial tax rate is small (large). An increase in the physical capital tax rate will increase the growth rate when savings are completely interest-inelastic. The effects of income taxes and lump-sum taxes on growth are also analysed.

Government expenditure,external and domestic public debt,and economic growth

This paper analyzes the relationship between government expenditure, tax on returns to assets, public debt, and growth in an endogenous growth model. Public debt is composed of two components, domestic debt and external debt. We show conditions for existence, uniqueness, and multiplicity of the steady states. More precisely, existence of steady state requires a sufficiently high productivity and a sufficiently low tax on returns to assets. We also provide the effects of an increase in the tax rate on returns to assets on the steady state. In particular, the relation between public spending and the tax rate has a bell shape. Domestic debt unambiguously increases with tax whereas external debt displays an inverted U‐shaped curve. A high tax rate leads to a reallocation of public debt in favor of domestic debt (to the detriment of external debt). The effect of taxation on consumption (and production) also displays a nonlinear pattern when the output elasticity of capital is lower than unity (the effect is monotonously increasing if this elasticity is unity). We also derive the conditions under which a tax increase can boost or reduce the balanced growth rate.     

影响中国税收增长率变动的经济因素分析——基于1978-2006年中国税收收入时间序列数据

近年来,中国税收呈现高增长态势。税收增长率远超经济增长率,税收高速增长以及税收结构不合理在一定程度上抑制了消费增长。然而,影响税收增长率变动的经济因素是多元的,主要受到经济增长水平、价格水平等影响。实证分析表明,经济波动决定税收增长率的变动,经济波动与税收增长率变动存在长期均衡变动关系,价格对税收增长率也有较大影响。     

Public investment,taxation, and long-run output in economies with multi-level governments

This paper examines the dynamic effects of taxation and investment on the steady state output level of an economy. A simple neoclassical growth model with different tiers of government is developed. The initial focus is on governments that aim to maximise their citizens' welfare and economic performance by providing consumption goods for private consumption and public capital for private production. It is shown that a long-run per capita output maximising tax rate can be derived and that there also exists an optimal degree of fiscal decentralisation. The analysis then extends to the case where governments attempt instead to maximise their own tax revenue to fund expenditures which do not contribute to the utility of their citizens. Three different cases of taxation arrangement are considered: tax competition, tax sharing, and tax coordination. The modeling shows that intensifying tax competition will lead to an increase in the aggregate tax rate as compared to the cases of sharing and coordination amongst governments. These tax rates are both higher than the long-run per capita output maximising rate that was implied under the welfare maximising government scenario.     

财政政策、货币政策与国外经济援助

本文通过把国外经济援助分成直接对私人的经济援助和直接对政府的经济援助来讨论这两类经济援助对政府财政政策和货币政策的影响。我们发现对私人的经济援助的增加可以使得私人消费水平和政府公共消费水平增加 ,但是它也导致政府收入税税率和通货膨胀率的提高 ;另一方面 ,对政府的经济援助增加可以使得均衡时的私人资本存量、私人消费水平和政府公共消费水平增加 ,同时可以使得均衡时的收入税税率和通货膨胀率下降。     

How should a government finance pension benefits?

Based on an earlier report by Ono (2010), this paper presents consideration of a consumption tax and examines how tax reform to maintain the neutrality of pension benefits affects the income growth rate and the employment rate. A decrease in the rate of worker contribution (labour income tax rate) with an increase in a consumption tax raises employment, but the effect on income growth is ambiguous. A decrease in the rate of firm contribution with an increase in the consumption tax decreases employment and facilitates income growth. Therefore, if the unemployment rate must be decreased, then pension reform with a decrease in the rate of worker contribution should be selected. The results derived through the study described in this paper are consistent with the empirical facts. Moreover, for these analyses, we assume the other production function and confirm the robustness of the obtained results.     

Monetary policy in a cash‐in‐advance economy: employment, capital accumulation, and the term structure of interest rates

Abstract.  In this paper we study the effects of monetary policies on employment, capital accumulation, consumption, and the term structure of interest rates in a cash‐in‐advance economy, where money is required for consumption expenditures. Monetary policy involves targeting the inflation rate. The detailed dynamics of the model are fully worked out. As no numerical analysis is involved, we are able to identify very clearly the different channels through which monetary policy will impinge on the important macroeconomic variables. The model is also used to discuss the 'Great Canadian Slump.' JEL Classification: E52 and E43     

Fiscal expansion, monetary policy, interest rate risk premia, and wage reactions

We examine the macroeconomic implications of fiscal policy in a small open economy, with emphasis on the interactions between fiscal, monetary and labour market policies. The paper uses the NBNZ-DEMONZ macroeconometric model. Novel features of the model are that it includes an endogenous interest rate risk premium (IRRP), and forward-looking monetary and fiscal policy reaction functions which capture the essence of New Zealand's Reserve Bank and Fiscal Responsibility Acts. The most important empirical result is that the postulated IRRP, proxying financial market mechanisms, can contribute at least as much as the monetary policy reaction function to maintaining price stability. Also of significance are that an income tax cuts package shows more damped real GDP and underlying inflation paths than does an expenditure increases equivalent; and that the inflationary and real sector impacts of a personal income tax cut package depend heavily on how the cut is `shared' between firms and workers. The nature and interdependence of monetary and fiscal policies and labour market conditions are therefore crucial to the macroeconomic outcomes.     

Tax competition,tax coordination and tax harmonization: The effects of EMU

There is little doubt that the step towards a monetary union in Europe will increase both the distorionary effects of existing differences in national tax systems and the intensity of tax competition for internationally mobile commodity and factor tax bases. This paper discusses selected issues of commodity and capital tax coordination that are likely to be affected by monetary unification. Starting from the distortive present scheme of value-added taxation in Europe we first analyze the effects of a switch to a general origin-based VAT as a way to maintain national tax rate autonomy over this important tax base. While an origin-based VAT would neither distort trade flows — both within the EU and with third countries — nor investment decisions in the long-run, its short-run effects are likely to be severe in the absence of exchange rate flexibility. In the field of capital taxation the focus switches to the feasibility of regional harmonization measures when there is no cooperation with the rest of the world. We argue that in a monetary union the mobility costs of capital will be significantly lower within the EU as compared to outside investments. This provides an efficiency argument for minimum source taxes on both interest income and corporate profits even if cooperation with third countries is infeasible.     

Tax Havens,Growth, and Welfare

This paper develops an endogenous growth model featuring tax havens, and uses it to examine how the existence of tax havens affects the economic growth rate and social welfare in high‐tax countries. We show that the presence of tax havens generates two conflicting channels in determining the growth effect. First, the public investment effect states that tax havens may erode tax revenues and in turn decrease the government's infrastructure expenditure, thereby reducing growth. Second, the tax planning effect of tax havens reduces marginal cost of capital and hence encourages capital accumulation so as to spur economic growth. The overall growth effect is ambiguous and is determined by the extent of these two effects. The welfare analysis shows that tax havens are more likely to be welfare‐enhancing if the government expenditure share in production is low, or the initial income tax rate is high. Moreover, the welfare‐maximizing income tax rate is lower than the growth‐maximizing income tax rate if tax havens are present.
