Budget deficits,money growth and inflation: the Turkish evidence

The paper investigates the long-run relationships between budget deficits, inflation and monetary growth in Turkey considering two alternative trivariate systems corresponding to the narrowest and the broadest monetary aggregates. While the joint endogeneity of money and inflation rejects the validity of the monetarist view, lack of a direct relationship between inflation and budget deficits makes the pure fiscal theory explanations illegitimate for the Turkish case. Consistent with the policy regime of financing domestic debt through the commercial banking system, budget deficits lead to a growth not of currency seigniorage but of broad money in Turkey. This mode of deficit financing, leading to the creation of near money and restricting the scope for an effective monetary policy, may not be sustainable, as the government securities/broad money ratio cannot grow without limit.     

Disequilibrium dynamics with monetarist price expectations

In this note we sketch the main features of the dynamic evolution of a rationed equilibrium macroeconomic model in which prices and wages respond to excess demands and inflation expectations, and the money stock is endogenous. We postulate monetarist inflation expectations, i.e., expected inflation is assumed to be equal to the current percentage rate of change of the money stock. If the system is stable, monetarist inflation expectations are asymptotically rational.     

How justified is abandoning money in the conduct of monetary policy in Australia on the grounds of instability in the money‐demand function?

The role of money in the design and conduct of monetary policy has reemerged as an important issue in both advanced and developing economies, especially since the 2007 global financial crisis. A growing body of recent literature suggests that the causal relationship between money supply growth and inflation remains intact across countries and over time and that this relation is not conditional on the stability of the money‐demand function or whether money is endogenous or exogenous. Moreover, critical for a rule‐based monetary policy is the presence of a long‐run stable money‐demand function, rather than a short‐run money‐demand model that may exhibit instability for many reasons, including problems with estimating a money‐demand model with high‐frequency data. Provided that a stable money‐demand function exists, it could be useful to establish long‐run equilibrium relations among money, output, prices, and exchange rates, as the classical monetary theory suggests. Within this analytical framework, this paper addresses the question of whether money has any role in the conduct of monetary policy in Australia. The conventional wisdom is that the money‐demand function in Australia has been unstable since the mid‐1980s due to financial deregulation and reforms; this led to a change in the strategy of monetary policy for price stability in the form of inflation targeting that ignores money insofar as inflation and its control are concerned. This paper reports empirical findings for Australia, obtained from a longer quarterly data series over the period 1960Q1–2015Q1, which suggest that instability in the narrow‐money‐demand function in Australia was primarily due to the exclusion of variables which have become important in the deregulated environment since the 1980s. These findings are confirmed by an expanded form of the narrow‐money‐demand function that was found stable over the past two decades, although it experienced multiple structural breaks over the study period. The paper draws the conclusion that abandoning the monetary aggregate as an instrument of monetary policy in Australia, under a rule‐based monetary policy such as inflation targeting, cannot be justified by instability in the money‐demand function or even by lack of a causal link between money supply growth and inflation.     

Decentralized Policymaking in a Long‐run Growth Model with Seigniorage and Taxes

The paper introduces decentralized policymaking into a game‐theoretic model with output growth through capital accumulation, and in which the determination of taxes, seigniorage and the long‐run growth rate of the economy reflects the strategic interactions between the government, the central bank and the private sector. The paper investigates, among other things, the impact on the long‐run growth rate of a higher degree of inflation aversion of the central bank and a higher degree of inefficiency in the tax system.     

Tight money policies and inflation revisited

In this paper we reconsider the link between tight money policies and inflation in the spirit of Sargent and Wallace's (1981) influential paper, 'Some unpleasant monetarist arithmetic.' A standard neoclassical model with capital, bonds, and return-dominated currency is used. The potential for tight-money policies to be inflationary (unpleasant arithmetic) exists, even when the real interest rate is below the growth rate of the economy. Additionally, the likely observability of unpleasant arithmetic in real world economies is shown to depend crucially on the type of monetary policy rule that is used. JEL Classification: E52, E63
Un autre coup d'œil sur la relation entre politiques monétaires restrictives et inflation. Ce mémoire ré-examine la relation entre politiques monétaires restrictives et inflation dans l'esprit du travail de Sargent et Wallace (1981) 'Some Unpleasant Monetarist Arithmetic'. Les auteurs utilisent un modèle néo-classique standard avec capital, débentures et une monnaie dont les rendements sont dominés par ceux d'autres réservoirs de valeur. La possibilité que les politiques monétaires restrictives soient inflationnistes existe même quand le taux d'intérêt réel est plus petit que le taux de croissance de l'économie De plus on montre que l'obtention de ces résultats déplaisants dans les économies concrètes dépend fondamentalement du type de règle monétaire qu'on utilise.     

Seigniorage and public good in an OLG model with cash-in-advance constraints

This paper is a contribution to the theory of the optimal monetary policy in overlapping generations models with a cash-in-advance constraint applying on old age consumption purchases. We are particularly interested in the study of seigniorage when the latter is used to finance public goods valued by consumers. Assuming that a public good enters the utility function and the existence of cash-in-advance constraints, we find a Laffer curve of seigniorage at steady-state. We also analyze the dynamic optimal monetary policy when the government maximizes an intertemporal social welfare function and can only resort to seigniorage to finance the purchases of the public good. We show that the optimal rate of money growth may be strictly higher than the one which maximizes steady-state seigniorage: the optimal amount of seigniorage may lie on the decreasing part of the Laffer curve of seigniorage. We finally suppose that the government can use lump-sum taxes in addition to seigniorage. Then, the Friedman rule prevails and public expenditures are only financed through lump-sum taxes.     

Hyperinflation in Zimbabwe: money demand,seigniorage and aid shocks

Zimbabwe experienced record hyperinflation of 80 billion per cent per month in 2008. This article uses new data from Zimbabwe to investigate money demand under hyperinflation using an autoregressive distributed-lag model for the period 1980–2008. The results produce plausible convergence rates and long-run elasticities, indicating that real-money balances are cointegrated with the inflation rate and signifying an equilibrium relationship between the two series. Evidence is also presented suggesting prices were driven by increases in the money supply rather than by changes in price setting behaviour. The article uses the estimated elasticity on the inflation variable to calculate the maximum level of seigniorage revenue that could be raised in the economy. Actual seigniorage levels increased dramatically after 2000, with inflation eventually exceeding the rate required to maximize this revenue stream. This is discussed in relation to international financing constraints and the collapse of the domestic tax base.     

Government financing in an endogenous growth model with financial market restrictions

Summary. In this paper, we develop an endogenous growth model with market regulations on explicitly modeled financial intermediaries to examine the effects of alternative government financing schemes on growth, inflation, and welfare. In the presence of binding regulation, there is always a unique equilibrium. We perform four alternative policy experiments; a change in the seigniorage tax rate, a change in the seigniorage tax base, a change in the income tax and a change in the fiscal-monetary policy mix. We find that in the presence of binding legal reserve requirements, a marginal increase in government spending need not result in a reduction in the rate of economic growth if it is financed with an increase in the seigniorage tax rate. Raising the seigniorage tax base by means of an increase in the reserve requirement retards growth and it has an ambiguous effect on inflation. An increase in income tax financed government spending also suppresses growth and raises inflation although not to the extent that the required seigniorage tax rate alternative would. Switching from seigniorage to income taxation as a source of government finance is growth reducing but deflationary. From a welfare perspective, the least distortionary way of financing an increase in the government spending requirements is by means of a marginal increase in the seigniorage tax rate. Under the specification of logarithmic preferences, the optimal tax structure is indeterminate. Received: March 20, 2000; revised version: June 26, 2001     

Money, capital, and real liquidity effects with habit formation

Abstract.  The money in utility model is reconsidered in the presence of endogenous labour and habits. With standard assumptions about preferences and a policy rule that sets the nominal interest rate by adjusting the growth rate of money, the model exhibits superneutrality in the steady state. Nevertheless, habits give rise to real liquidity effects in the short run. After an increase in the nominal interest rate, employment falls, resulting in a fall in capital accumulation and in the short‐ and long‐term real interest rates. The adjustment of the capital stock is non‐monotonic. Employment and the short‐ and long‐term real interest rates may also adjust non‐monotonically. JEL classification: E22, E52, E58     

Optimal Monetary Policy with Price and Wage Rigidities

In this paper, I search for an optimal configuration of parameters for variants of the Taylor rule by using an accurate second‐order welfare‐based method within a fully microfounded dynamic stochastic model, with price and wage rigidities, without capital accumulation. A version of the model with distortionary taxation is also explicitly tested. The model is solved up to second‐order solution. Optimal rules are obtained by maximizing a conditional welfare measure, differently from what has been done in the current literature. Optimal monetary policy functions turn out to be characterized by inflation targeting parameter lower than in empirical studies. In general, the optimal values for monetary policy parameters depend on the degree of nominal rigidities and on the role of fiscal policy. When nominal rigidities are higher, optimal monetary policy becomes more aggressive to inflation. With a tighter fiscal policy, optimal monetary policy turns out to be less aggressive to inflation. Impulse‐response functions based on second‐order model solution show a non‐affine pattern when the economy is hit by shocks of different magnitude .     

The inflationary experiences of six developing countries in Asia: an investigation of underlying determinants

This paper investigates major deteminats of the inflation rate in six Asian developing countries. The sample includes low and moderate-high inflation cases. For the investigation a monetarist model of the inflation rate adjusted to account for important external factors is used. The results show that the growth of the money stock was not a primary source of inflation in all countries. However, various factors that influence the public's willingness to hold money are behind inflationary pressures across countries. Among these, some are external factors stemming from changes in foreign interst rates and import prices. Overall, the evidence suggests that the success of domestic policy in fighting inflation is highly dependent on the unique inflationary experience of each country.     

Central bank instruments, fiscal policy regimes, and the requirements for equilibrium determinacy

This paper examines the role of the monetary instrument choice for local equilibrium determinacy under sticky prices and different fiscal policy regimes. Corresponding to Benhabib et al.'s results for interest rate feedback rules [Benhabib, J., Schmitt-Grohé, S., Uribe, M., 2001. Monetary policy and multiple equilibria. American Economic Review 91, 167–185], the money growth rate should not rise by more than one for one with inflation when the primary surplus is raised with public debt. Under an exogenous primary surplus, money supply should be accommodating—such that real balances grow with inflation—to ensure local equilibrium determinacy. When the central bank links the supply of money to government bonds by controlling the bond-to-money ratio, an inflation stabilizing policy can be implemented for both fiscal policy regimes. Local determinacy is then ensured when the bond-to-money ratio is not extremely sensitive to inflation, or when interest payments on public debt are entirely tax financed, i.e., the budget is balanced.     

The performance and robustness of simple monetary policy rules in models of the Canadian economy

Abstract.  In this paper, we evaluate seven simple monetary policy rules in a wide range of models of the Canadian economy. Our results indicate that none of the seven simple policy rules we examined is robust to model uncertainty, in that no single rule performs well in all models. In fact, our results show that the performance of some of the simple rules, particularly rules with interest rate smoothing and rules with a high coefficient on the inflation gap, can substantially deviate from that of the optimal rule and can even be unstable in some models. Furthermore, we find that "open‐economy" rules do not perform well in many models. We find that adding an exchange rate term to a simple policy rule often increases the value of the policy‐maker's loss function. Although it is not robust, we find that a simple nominal Taylor‐type rule that has a coefficient of 2 on the inflation gap and 0.5 on the output gap outperforms the other simple rules in a certain class of models. However, even in those models, the loss‐function value of this simple rule can be substantially higher than that of the optimal or base‐case rule. JEL classification: E52, E58     

中国货币供给与通货膨胀的关联性研究

关于货币供给与通货膨胀的关联性,学者们还没有形成一致的看法.理论上,货币供给与通货膨胀具有一定的关联性.通货膨胀有需求拉动型和成本推动型,在通货膨胀的原因中有“货币因素”,也有“非货币因素”.实证检验表明:中国货币供应量与物价指数不存在长期的稳定均衡关系,但货币供应量是物价指数的格兰杰原因,反之则不然.事实上,中国通货膨胀或通货膨胀压力一方面是与货币供给有关,另一方面还与结构性因素有关.因此,要实现中国经济的低通胀运行:一是实行总量均衡和结构合理的货币供给模式;二是采取更有效的货币政策;三是推进经济结构调整,实现国际收支平衡;四是深化金融体系改革,增强中央银行货币控制能力;五是进行汇率机制改革;六是通过财政政策调整供需结构.     

Can growth-enhanced monetary policy improve welfare when people seek social status?

This paper examines the growth and welfare effects from an increase in the rate of money supply in an Ak type growth model with a relative wealth-enhanced social status motive, production externalities, and liquidity constraints. When only consumption is constrained by liquidity, fast money supply can hasten output growth unless seigniorage revenue is wasted and production externalities do not exist. We find that even though money growth normally promotes economic growth, it does not improve welfare when capital stock is over-accumulated. In general, an optimal monetary policy minimizes seigniorage. Our results also conclude that the optimal monetary policy rarely follows the Friedman rule.     

Deficit spending,money, and inflation: Some international empirical evidence

An attempt is made, in this study, to examine the monetarist propositions regarding the effects of budget deficits on money growth and inflation for ten industrialized countries. To this end, a two-equation econometric model consisting of the money supply growth and inflation equations has been specified and estimated. Based on the results, it is concluded that, in general, the government budget deficit is not a determinant of money supply growth or of inflation (directly or indirectly). The U.S. is an exception with some statistical evidence of direct and indirect effects of the budget deficit on inflation.     

Inflation and Unemployment in General Equilibrium*

When labor is indivisible, there exist efficient outcomes with some agents randomly unemployed, as in Rogerson (1988) . We integrate this idea into the modern theory of monetary exchange, where some trade occurs in centralized markets and some in decentralized markets, as in Lagos and Wright (2005) . This delivers a general equilibrium model of unemployment and money, with explicit microeconomic foundations. We show that the implied relation between inflation and unemployment can be positive or negative, depending on simple preference conditions. Our Phillips curve provides a long‐run, exploitable, trade‐off for monetary policy; it turns out, however, that the optimal policy is the Friedman rule.     

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.     

Floor systems for implementing monetary policy: Some unpleasant fiscal arithmetic

An increasing number of central banks implement monetary policy via a channel system or a floor system. We construct a general equilibrium model to study the properties of these systems. We find that a floor system is weakly optimal if and only if the target rate satisfies the Friedman rule. Unfortunately, the optimal floor system requires either transfers from the fiscal authority to the central bank or a reduction in seigniorage payments from the central bank to the government. This is the unpleasant fiscal arithmetic of a floor system. When the central bank faces financing constraints on its interest expense, we show that it is strictly optimal to operate a channel system.     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.
