AVOIDING THE INFLATION TAX*

I study the effects of inflation on the purchasing behavior of buyers in the Lagos–Wright monetary economy. The standard framework fails to capture the long‐standing intuition that when inflation increases, agents try to spend their money holdings speedily. I propose a simple, realistic extension in which buyers can rebalance their money holdings only sporadically (i.e., not every period). I show that, in such a case, higher inflation can induce buyers to spend their money faster by frontloading their consumption and searching more intensively for transactions. These trade distortions have, traditionally, been associated with the economic costs of inflation.     

Fiscal policy,macroeconomic performance and industry structure in a small open economy

We analyse how fiscal policy affects both the macroeconomy and the industry structure, using a multi-sector macroeconomic model of the Norwegian economy with an inflation targeting monetary policy. Our simulations show that the magnitude of the government spending and labour tax cut multipliers, whether monetary policy is active or passive, is comparable to what is found in the literature. A novel finding from our simulations is that the industry structure is substantially affected by an expansionary fiscal policy, as value added in the non-traded goods sector increases at the expense of value added in the traded goods sector. Moreover, expansionary fiscal policy reduces the mark-ups in the traded goods sector, while the mark-ups are roughly unchanged in the non-traded goods sector. The contraction of activity in the traded goods sector increases when monetary tightening accompanies the fiscal stimulus. Hence, we find that such a policy mix is likely to produce significant de-industrialization in a small open economy with inflation targeting.     

Monetary policy and fiscal limits with no-default

This paper discusses monetary and fiscal policy interactions that stabilize government debt. Two distortions prevail in the model economy: income taxes and liquidity constraints. Possible obstructions to fiscal policy include a ceiling on the equilibrium debt-to-GDP ratio, zero or negative elasticity of tax revenues, and a political intolerance of raising tax rates. At the fiscal limit two mechanisms restore solvency: fiscal inflation, which reduces the real value of nominal debt, and open market operations, which diminish the size of government debt held by the private sector. Three regimes achieve this goal. In all regimes monetary policy is passive. In all regimes a muted tax response to government debt is consistent with equilibrium. The propensity of a fiscal authority to smooth output is found to determine what is an acceptable response (in the form of tax rate changes) to the level of government debt, while monetary policy determines the timing and magnitude of fiscal inflation. Impulse responses show that the inflation and tax hikes needed to offset a permanent shock to transfers are lowest under nominal interest rate pegs. In this regime, most of the reduction in the real value of government debt comes from open market purchases.     

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.     

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 inflation tax in an open economy with imperfect competition

This paper studies the national welfare maximizing inflation tax in an open economy with imperfect competition. It shows that the presence of a monopolistic distortion dampens the incentive to engage in strategic use of the inflation tax. If this dampening effect is strong enough, monetary policy becomes completely inward-looking, restoring the Friedman rule as an equilibrium strategy regardless of the actions of the foreign government. This aspect of the policy interaction—driven entirely by the presence of imperfect competition—is important because it determines the underlying structure of the policy game and is therefore crucial for determining whether or not there exist welfare gains from international monetary cooperation.     

Money demand, the Cagan model, testing rational expectations vs adaptive expectations: The case of Turkey

This paper estimates the Cagan type demand for money function for Turkish economy during the period 1986:1–1995:3 and tests whether Cagan's specification fits the Turkish data using an econometric technique assuming that forecasting errors are stationary. This paper also tests the hypothesis that monetary policy was implemented in aiming to maximize the inflation tax revenue. Finally, the Cagan model is estimated with the additional assumption of rational expectations for Turkey for the considered period.

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。     

A Macroeconomic Stabilization Game: Design,Development, and Testing

The author describes a computer game involving macroeconomic stabilization policy. Students are asked to take the part of government in manipulating tax rates, expenditures, monetary policy in an attempt to influence employment and inflation in an open economy.     

Are Progressive Income Taxes Stabilizing?

We assess the stabilizing effect of progressive income taxes in a monetary economy with constant returns to scale. It is shown that tax progressivity reduces, in parameter space, the likelihood of local indeterminacy, sunspots and cycles. However, considering plausibly low levels of tax progressivity does not ensure saddle‐point stability and preserves as robust the occurrence of sunspot equilibria and endogenous cycles. It turns out that increasing progressivity, through its impact on after‐tax income, makes labor supply more inelastic. However, even when large, tax progressivity does not neutralize the effects of expected inflation on current labor supply which may lead to expectation‐driven business fluctuations.     

The optimal choice of monetary policy instruments in a small open economy

Abstract.  This paper studies how the nature of shocks affects the optimal choice of monetary policy instruments in a small open economy. Three classic rules, fixed exchange rates, monetary targeting, and inflation targeting are studied and ranked by comparing with the optimal monetary policy under commitment. We find that the ranking of the simple rules can be mapped to the terms-of-trade variability that the rule allows relative to what a particular shock optimally calls for. It turns out that inflation targeting dominates the other two rules under productivity or velocity shocks, whereas monetary targeting is the best performer under fiscal shocks.     

On the Effects of Inflation Shocks in a Small Open Economy

The effects of monetary policies remain always an important topic in macroeconomics. In the literature (closed and open economy), there is no theoretical as well as empirical consensus regarding the effects of monetary policies. In this paper we examine the real effects of inflation in an open economy. Australia is a classic example of a small open economy and is known to exercise inflation targeting. Using quarterly data from Australia and employing vector autoregressive (VAR) analysis, we provide evidence that inflation, both in the short and long run, negatively affects durable and non‐durable consumption and investment, and has a positive effect on the current account. Further, we show that consumption of durable goods is more sensitive than the consumption of non‐durables during the initial periods following inflationary shocks.     

Optimal long-run inflation with occasionally binding financial constraints

This paper studies the optimal long-run inflation rate in a simple New Keynesian model with occasionally binding collateral constraints that intermediate-good firms face on hiring labor. The paper finds that the optimal long-run annual inflation rate is around 1.5% if the economy is hit by a total factor productivity (TFP) shock and nearly 2.5% if the economy is subject to a markup shock. The shadow value of the collateral constraint is akin to an endogenous cost-push shock. Differently from usual cost-push shocks, however, this shock is asymmetric as it takes non-negative values only. Since the mean of this asymmetric endogenous cost-push shock is positive, inflation is also positive on average. In addition, a binding collateral constraint resembles a time-varying tax on labor, which the monetary authority can smooth by setting a positive inflation rate. More generally, the basic result is related to standard Ramsey theory in that optimal policy smoothes distortions over time.     

货币紧缩、产权性质与公司现金持有

宏观经济政策如何影响公司微观行为是最近几年比较新的领域。本文运用中国上市公司2001—2011年的年度数据,探讨了货币紧缩政策对公司现金持有的影响以及产权性质对这种影响的作用。本文发现,货币紧缩政策对公司的现金持有具有负向影响,即处于货币政策紧缩阶段,公司的现金持有会显著减少。相比于国有企业,货币紧缩政策对民营企业的现金持有影响更大,民营企业的现金持有在货币紧缩阶段减少得更多。本文进一步分析发现,在货币紧缩阶段,公司当期投资并未出现下降。这说明在货币紧缩阶段,为确保当期投资顺利进行,公司会使用自有现金来补充由于银行信贷减少引起的资金不足。     

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.     

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 hidden economy in Spain – A monetary estimation, 1964–1998

The aim of this paper is to estimate the level and evolution of hidden income in Spain during the period 1964–1997. To this end, we employ the well-known monetary approach which supposes that the hidden economy is a response on the part of the economic agents to the tax burden, one which manifests itself in an excess of demand for currency. The estimation has been made on the basis of the ADL technique, an ECM and Johansen's cointegration approach. The period chosen was characterised by multiple institutional changes, an increase in the tax burden and wide-ranging financial liberalisation. This has obliged us to formulate a specific monetary model to estimate the hidden economy and is one of the original features of that model.

CALCULATING WELFARE COSTS OF INFLATION IN A SEARCH MODEL WITH PREFERENCE HETEROGENEITY: A CALIBRATION EXERCISE

Using US cross‐sectional data, this paper calculates the welfare cost of a 10 percent inflation for different individuals and finds that the difference in cost between the poorest 20 percent, measured by their net worth, and the richest 20 percent is in the order of 102 percent. That is, a poor person is on average willing to forgive 102 percent more of their total consumption in order to have inflation reduced from 10 percent to 0. In absolute terms this represents a cost of 0.461 percent of consumption for the poorest and 0.228 percent for the richest. I accomplish this by introducing preference heterogeneity in a monetary search model first developed by Lagos and Wright, and calibrate the model to match each agent's type of cash holdings, approximated by their holdings in transactional accounts that bear almost no interest, as a fraction of their net worth using data from the Survey of Consumer Finances. I also show that this welfare difference increases to 130 percent (2.28 percent for the poorest 20 percent and 0.992 percent for the richest 20 percent) whenever frictions in the use of money are imposed (holdup problem). This distributional effect is further augmented if more frictions in the terms of trade are present. The ability to explicitly model these frictions is the advantage of using this model. Hence, inflation in this framework, as other studies have shown, acts as a regressive consumption tax; and this regressiveness is augmented with the holdup problem.     

紧缩性货币政策应对当前通货膨胀的低效性

近期我国出现了居民消费物价指数快速上涨的现象,通货膨胀压力逐步显现,货币当局采取了一系列紧缩性货币政策。然而当前通货膨胀的重要特征是结构性价格调整,其深层次原因是扭曲的要素价格体系的调整和经济增长方式的转变,数据也显示货币供给量的平稳增长和通货膨胀率存在背离的现象。因此,继续采取紧缩性货币政策应对当前通货膨胀是低效的,应当综合采取多种政策手段实现对经济的调控。
