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.     

Money, Neutrality of Consumption Taxes, and Growth in Intertemporal Optimizing Models

This paper considers the effects of a proportional consumption tax with the same rate over time on the real growth path of a monetary economy. The analysis uses a variety of stylized monetary growth models in which the individual's consumption-saving decision is based on intertemporal utility maximization (e.g. the money-in-utility, transaction-costs, and cash-in-advance models). The neutrality of consumption taxation depends on the assumed role of money in the respective models, even though the tax revenue collected is fully rebated to consumers as lump-sum transfers. The consumption tax is generally superior to inflation tax (i.e. the rate of monetary growth) in terms of steady-state welfare, as long as the labour supply is fixed.

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。     

POSITIONAL CONCERNS IN AN OLG MODEL: OPTIMAL LABOR AND CAPITAL INCOME TAXATION*

This article concerns optimal income taxation under asymmetric information in a two‐type OLG model when individuals’ relative consumption matters. Positional concerns affect the policy choices via two channels: (i) the average degree of positionality and (ii) positionality differences between the low‐ability type and the mimicker. Under plausible empirical estimates, the marginal labor income tax rates become substantially larger, and the absolute value of the marginal capital income tax rate of the low‐ability type becomes substantially smaller, than in the conventional model. In addition to measures of reference consumption based on average consumption, we also address within‐generation and upward comparisons.     

Inflation and capital accumulation in an OLG model with money in the production function

This article analyses the consequences of the money supply growth rate on capital intensity and economic growth in an overlapping-generations model with real balances entering the production function. Within this theoretical framework, anticipated inflation generates an ambiguous effect on capital–labour ratio, because two forces work simultaneously in opposite directions: one driving towards a pure Tobin effect (due to the OLG demographic structure of the economy) and the other pushing down the capital stock (due to the productive role of real balances). Despite the unclear effects exerted on capital intensity, higher monetary growth rates unambiguously reduce real money demand, consumption, total wealth and welfare.     

Growth and Welfare Effects of Tax Cuts: The Case of a Productive Public Input with Technological Risk

This paper analyzes the dynamic impact of tax cuts within a stochastic model of endogenous growth with a congested public input. A decreasing taxation of deterministic income parts leads to the well-known positive growth effect. Nevertheless, due to the insurance effect associated with the taxation of stochastic income flows, the overall growth impact of taxation is ambiguous. It is shown that the optimal structure of financing government expenditure does not only depend on the degree of rivalry but also on the degree of risk aversion. The optimal real value of government debt decreases with a rise in congestion. We identify that in the case of proportional congestion, the base for tax cuts should be the growth neutral consumption tax. Maximizing the growth rate does not automatically coincide with maximizing welfare. Hence, the base for tax cuts gains importance to realize a welfare optimal policy.     

(In)Effective tax enforcement and demand for cash

Cash holdings have increased worldwide in recent years. It is well known that a higher tax burden is typically an important factor in explaining an increase in cash holdings. However, the role of tax enforcement is less known. To explore the effect of tax enforcement on cash holdings, we study fiscal reform carried out in a large, developing country. In mid-2013, Mexico tried to raise tax revenues by enrolling more taxpayers and introducing electronic invoices to counter a secondary market in illegal invoices. Based on a transaction-based model of money demand, we find an ambiguous effect of tougher tax enforcement on money holdings. If institutions are ineffective, the model predicts an increase in cash holdings after tougher enforcement. To test this issue empirically, we propose a vector error correction (VEC) specification for money demand. The results suggest that a tax enforcement policy implemented under a weak institutional framework can exacerbate cash holdings.     

Optimal firm behaviour under different fiscal regimes

This paper presents a theoretical framework for studying tax effects on optimal entrepreneurial behaviour; this is done within the context of a partial equilibrium model of the firm. Several regimes of corporate income taxation are evaluated with respect to their (non-)neutrality characteristics. Subsequently, the degrees of tax shifting and tax compensation have been derived by means of a model specified in rather simple terms. Evaluating it numerically, we find that the Dutch regime tends to neutrality, or possibly to slightly negative non-neutrality.     

The Optimal Tax Treatment of Housing Capital in the Neoclassical Growth Model

Should housing capital be taxed like other forms of capital? We analyze this question within a version of the neoclassical growth model. We derive the optimal tax treatment of housing capital vis‐à‐vis business capital allowing for relatively general household preferences. In the first‐best, the tax treatment of business and housing capital should always be the same. In the second‐best, in contrast, the optimal tax treatment of housing capital depends on the elasticities of substitution between nonhousing consumption, housing, and leisure. This is because housing taxation may be used to alleviate the distorting effect of taxing labor. As a result, the optimal tax treatment of housing capital may be different from that of business capital. We complement these analytical results with a numerical analysis.     

Optimal composition of government public capital financing

Most recent studies on growth models with public investment in infrastructure (public capital) presume that public capital is financed by income taxation. However, in the model where money is demanded for transactions, this paper finds that optimal public capital financing in general involves utilizing both income taxation and seigniorage. In such a case, the optimal income tax rate is less than the output elasticity of public capital, a reasonable result compared with empirical evidence.     

Welfare improving distributionally neutral tax reforms

In a new model with incomplete markets, I quantitatively determine tax reforms that are welfare improving, distributionally neutral, and leave the budget balance unchanged in the long run. I consider a new reform. I eliminate capital income taxation and replace it with progressive consumption taxation, consisting of taxing necessities and luxuries at different rates. I compare steady states under various tax regimes. I find that progressive rather than uniform consumption taxation generates higher welfare gains in the long run and during the transition to the steady state. While this type of reform achieves redistribution neutrality only in the long run, it generates welfare gains for the whole population during the transition.     

Optimal income taxation when couples have endogenous bargaining power

This study examines the optimal income taxation for a two-earner household, where the couple bargains over their private goods consumption and time allocation between work and leisure. In the model, bargaining power is determined endogenously by the income gap between the two earners. Conventional studies have shown that the higher income tax rate should be imposed on the individual with the smaller wage elasticity, typically the individual with the higher productivity. In contrast to conventional argument, this study shows that the optimal tax rate on the household member with the higher productivity is lower than that of the individual with the lower productivity if the required tax revenue is relatively small and the influence of the gender income gap on the power balance of the couple is moderate. This is because such a tax structure encourages the labor supply of the individual with the higher productivity to mitigate the decrease in the household’s consumption induced by income taxation.     

Seigniorage and Japanese fiscal sustainability: Simulation analysis using an overlapping generations model

This study examines two tax policies for achieving fiscal sustainability in Japan: (i) an increase in consumption tax and (ii) consumption tax hike combined with inflation. To evaluate these policies from both fiscal and welfare perspectives, I develop a multi-period overlapping generations model with money. The results reveal that, compared to the first policy, the second policy can substantially delay the timing of and curb the increase in consumption tax through seigniorage revenue. This suggests seigniorage could be a useful tool for the Japanese government in resolving its fiscal problems. In addition, in an aging Japan, the second policy can enhance future generations’ utility. Because inflation reduces money holdings and utility of the elderly, policies that cause inflation in the present but reduce it in the future improve the utility of future generations. From a social welfare viewpoint, such policies are desirable in a government that has foresight.     

Aggregate instability under balanced-budget consumption taxes: A re-examination

We re-examine the destabilizing role of balanced-budget fiscal policy rules based on consumption taxation. Using a one-sector model with infinitely-lived households, we consider a specification of preferences derived from Jaimovich (2008) [14] and Jaimovich and Rebelo (2009) [15] which is flexible enough to encompass varying degrees of income effect. When the income effect is not too large, we show that there exists a Laffer curve, which explains the multiplicity of steady states, and that non-linear consumption taxation may destabilize the economy, promoting expectation-driven fluctuations, if the elasticity of intertemporal substitution in consumption is sufficiently larger than one and the tax rate is counter-cyclical with respect to consumption. Numerical illustrations also show that consumption taxation may be a source of instability for most OECD countries for a wide range of structural parameters? configurations. We finally prove the robustness of our conclusions if we consider a discrete-time setup.     

Multiple reserve requirements in a monetary growth model

Summary. This paper considers a monetary growth model in which banks provide liquidity, and in which a government finances a deficit by printing money and selling bonds. In this context, I examine the possibility that the government may want to impose binding reserve requirements on banks' holdings of both money and government bonds. Conditions are established under which doing so increases steady state welfare and reduces the scope for indeterminacies. Furthermore, under a binding system of multiple reserve requirements we have that money is superneutral. On the other hand, if reserve requirements are imposed on cash holdings alone, increases in the steady state inflation rate adversely affect capital accumulation and long run real activity. Thus systems of multiple binding reserve requirements can insulate real activity from the consequences of inflationary taxation. Received: June 30, 2000; revised version: January 31, 2001     

Optimal taxation in a monetary economy with financial intrmediaries

The problem of optimal taxation when the government must levy distorting taxes to meet its revenue needs is considered for a monetary economy with financial intermediaries. In contrast to most other studies of optimal taxation in a monetary economy, money is treated as an intermediate good which is held because doing so economizes on the scarce resources that must be devoted to the exchange process. Attention is focused on the roles of the inflation tax, reserve requirements, and deposit taxes. The key result is that revenue considerations do not justify taxing cash and deposits. That is, the optimal tax structure calls for adopting the optimum quantity of money rule and setting deposit taxes to zero. When the optimal tax structure is in place, reserve requirements turn out to be irrelevant from both the fiscal and welfare perspectives.     

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.     

Fiscal Policy and Exchange Rates

This paper examines the dynamics of the nominal exchange rate and fiscal deficits in a continuous time optimizing general equilibrium model with OLG. It is shown that alternative financing modes of budget deficits imply different patterns of adjustment along the transitional path towards the steady-state equilibrium. In particular, the respect of public solvency without money financing is not sufficient to avoid the depreciation of the exchange rate in the long-run after a fiscal expansion. In addition, money and tax financing generate opposite intergenerational reallocation of wealth.     

Taxation when Borrowing is Costly*

The implications for taxation theory of a life-cycle model of consumption incorporating financial transactions costs are derived The equity case for progressive taxation is shown to correspond in a life-cycle setting, to an efficiency case. Individuals prefer a progressive tax system to a proportional one because the tax burden is lower when they are young and face high transactions costs of borrowing. Similarly, an income tax is preferred to a consumption tax. Unlike earlier models based on liquidity constraints, the model presented here involves a financial sector consuming real resources. This permits analysis of the tax treatment of financial services in a consumption tax system. Exemption of financial services will generally be desirable.     

Capital Taxation and External Accounts in a Small Growing Economy

The effects of capital taxation on external accounts depend on how government allocates the tax revenue. With government debt being endogenous, an increase in either the residential or territorial capital tax rate may decrease net foreign asset holdings. With intergenerational transfers being endogenous, an increase in either the residential or territorial capital tax rate may increase net foreign asset holdings. With government spending being endogenous, an increase in the residential capital tax rate may either deteriorate or have no effect on the external accounts.
