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.     

Is there Causal Relationship between Money Supply Growth and Inflation in China? Evidence from Quantity Theory of Money

This study examines the causal relationship between Chinese money supply growth and inflation, using the bootstrap Granger full‐sample causality test and sub‐sample rolling‐window estimation test to determine whether such a relationship in China supports the quantity theory of money. The result indicates that there is a unidirectional relationship from inflation to money supply growth. However, considering structural changes in two series, we find that short‐run relationships using full‐sample data are unstable, which suggests that full‐sample causality tests cannot be relied upon. Then, we use a time‐varying rolling‐window approach to revisit the dynamic causal relationship, and the results show that money supply growth has both positive and negative impacts on inflation in several sub‐periods, and in turn, inflation has the same effects on money supply growth for China. These findings are basically consistent with the modern quantity theory of money from the perspective of money supply and price level. When money supply growth does not outweigh output growth, inflation should not be curbed only by decreasing money supply. It notes that a stable money supply growth is critical to price level stability and economic development in China.     

A simple model for study of the determination of the price level and the interaction of monetary and fiscal policy

Summary A representative-agent model with money holdings motivated by transactions costs, a fiscal authority that taxes and issues debt, no production, and a convenient functional form for agents' utility is presented. The model can be solved analytically, and illustrates the dependence of price determination on fiscal policy, the possibility of indeterminacy, even stochastic explosion, of the price level in the face of a monetary policy that holdsM fixed, and the possibility of a unique, stable price level in the face of a monetary policy that simply pegs the nominal interest rate at an arbitrary level.In a rational expectations, market-clearing equilibrium model with a costlessly-produced fiat money that is useful in transactions, the following things are true under broad assumptions.- A monetary policy that fixes the money stock may (depending on the transactions technology) be consistent with indeterminacy of the price level—indeed with stochastically fluctuating, explosive inflation.- A monetary policy that fixes the nominal interest rate, even if it holds the interest rate constant regardless of the observed rate of inflation or money growth rate, may deliver a uniquely determined price level.- The existence and uniqueness of the equilibrium price level cannot be determined from knowledge of monetary policy alone; fiscal policy plays an equally important role. Special case models with interest-bearing debt and no money are possible, just as are special cases with money and no interest-bearing debt. In each the price level may be uniquely determined.Determinacy of the price level under any policy depends on the public's beliefs about what the policy authority would do under conditions that are never observed in equilibrium.These points are not new. Eric Leeper [1991] has made most of them within a single coherent model. Woodford [1993], in a representative agent cash-in-advance model, has displayed the possibility of indeterminacy with a fixed quantity of money and the possibility of uniqueness with an interest-rate pegging policy. Aiyagari and Gertler [1985] use an overlapping generations model to make many of the points made in this paper, without discussing the possibility of stochastic sunspot equilibria. Sargent and Wallace [1981] and Obstfeld [1983] have also discussed related issues.This paper improves on Leeper by moving beyond his analysis of local linear approximations to the full model solution, as is essential if explosive sunspot equilibria are to be distinguished from explosive solutions to the Euler equations that can be ruled out as equilibria. It improves on the other cited work by pulling together into the context of one fairly transparent model discussion of phenomena previously discussed in isolation in very different models.We study a representative agent model in which there is no production or real savings, but transactions costs generate a demand for money. The government costlessly provides fiat money balances, imposes lump-sum taxes, and issues debt, but has no other role in the economy. We make restrictive assumptions about the form of the utility function and the form of a transactions cost term in the budget constraint.The model could be extended to include production, capital accumulation, non-neutral taxation, productive government expenditure, and a more general utility function without affecting the conclusions discussed in this paper. Indeed the model I informally matched to data in an earlier paper [1988] makes some such extensions. While such an extended model is more realistic, it is harder to solve. The version in my earlier paper [1988] was solved numerically and simulated. The bare-bones model of this paper allows an explicit analytic solution that may make its results easier to understand.This paper improved following comments from participants at seminars at Yale and the Atlanta Federal Reserve Bank. Eric Leeper and James Robinson were particularly helpful. Comments from Michael Woodford led to important corrections and clarifications.     

On the short-run and long-run demand for money

This paper makes precise the relationships between short-run and long-run demand for money, using methods commonly employed in growth models. It estimates these demand functions with quarterly French data and tests the validity in France of the modern version of the quantity theory of money. The effects of inflation on the demand for money are studied both in the short run and the long run. The speed of adjustment of money balances towards their long-run level is measured.

CONTINGENT PRICES AND MONEY*

Price posting with directed search is a widely used trading mechanism. Coles and Eeckhout showed that if sellers are allowed to post prices contingent on realized demand instead of one price, then there is real market indeterminacy. In this article, we fit this contingent price‐posting protocol into a monetary economy. We show that, as long as holding money is costly, there exists a unique equilibrium rather than a continuum. In this equilibrium sellers post a low price for when the buyer is alone, a high price for when several buyers show up, and buyers randomize between sellers and money holdings.     

The effects of monetary policy in a small open economy: the case of Portugal

In this article, I analyse the macroeconomic effects of monetary policy on the Portuguese economy. I show that a positive interest rate shock leads to: (i) a contraction of real GDP and a substantial increase of the unemployment rate; (ii) a quick fall in the commodity price and a gradual decrease of the price level and (iii) a downward correction of the stock price index. It also produces a ‘short-lived liquidity effect’ and helps explain the negative comovement between bonds and stocks. In addition, I find evidence suggesting the existence of a money demand function characterized by small output and interest rate elasticities. By its turn, the central bank’s policy rule follows closely the dynamics of the money markets. Finally, both the real GDP and the price level in Portugal would have been higher during almost the entire sample period if there were no monetary policy surprises.     

Money creation and credit multipliers ∗

The standard objections against the quantity theory of money, based on the instability of the velocity of money, are insufficient to discard this long-held monetary theory. The principal criticism of the theory rests on the determination of the money supply. The supply of money is a dependent variable, not an independent one. The demand for credit determines the quantity of money, or at the very least bankers and borrowers share the responsibility. Causality is thus reversed. It is necessary to abandon the concept of money multipliers, which are relics of the quantity theory of money. Bankers can, if they so desirerespond without limitto demands for credit. They are not tied by a fixed amount of pre-existing assets. The goal of the article is to outline an explanation of these statements and provide a vision of monetary theory that is different from that usually taught.     

Is the optimum quantity of money compatible with the unique price level under laissez-faire?

The purpose of this paper is to set forth a general equilibrium model to demonstrate that even if the real social costs of producing money are positive, the optimum quantity of money is incompatible with the unique price level under laissez-faire if zero-degree homogeneity of the production-maintenance cost function in M and P is assumed.     

Long-Run Links among Money, Prices and Output: Worldwide Evidence

Abstract. Starting from the quantity theory of money we analyse the dynamic relationships between money, real output and prices for an unbalanced panel of 110 economies. Complementary to trivariate analyses we also adopt a P-star model explaining inflation via an equilibrium price level (P-star), which in turn depends on potential output and money. A key issue of the paper is the cross-sectional stability of estimation and inference results. We find cointegration among the considered variables. Particularly for high inflation countries homogeneity between prices and money cannot be rejected. Given homogeneity we find evidence for an error-correction mechanism linking current price changes and the lagged price gap. Parameter estimates indicating the adjustment towards the price equilibrium are larger in absolute value for high inflation countries. The latter results indicate that central banks, even in high inflation countries, can improve price stability by controlling monetary growth.     

THOMAS TOOKE AND THE INFLUENCE OF THE RATE OF INTEREST ON PRICES: IMPLICATIONS FOR DISTRIBUTION THEORY

Thomas Tooke included money interest among the determinantsof normal money production costs, together with money wagesand production techniques. This inclusion permitted him to explainthe existence, in actual fact, of a direct relationship betweenthe rate of interest and the level of prices. He did not developthe implications for distribution theory of his view of theinfluence of the rate of interest on the price level. In thepresent article it is maintained that the rate of interest emergesfrom Tooke's analysis as the regulator of the ratio of pricesto money wages, with the corollary that there is implicit init a causal relationship between money interest and normal profitthat goes from the former to the latter. This may be connectedwith Sraffa's suggestion of a determination of the rate of profitby the money rate of interest and lend it the support of Tooke'sscrupulous analysis of facts.     

Wealth effects,treasury bill financing,and stability

This note examines the stability of government financing through capital-certain, variable interest bonds in the context of a fixed price macromodel. In contrast to the financing by perpetuities, it is shown that a wealth effect on expenditures may be destabilising, particularly if the interest elasticity of money demand is low.     

Asymmetric responses of money demand to oil price shocks in Saudi Arabia: a non-linear ARDL approach

Saudi Arabia is an open oil-based economy with fixed exchange rates; therefore, it has limited monetary policy autonomy. Using non-linear autoregressive distributed lag approach, this article investigates the asymmetric effects of oil price shocks on the demand of money in Saudi Arabia over the period 1990:Q1–2014:Q4. The empirical results show evidence of positive long run but asymmetric effects of oil price shocks on the money demand. In particular, we find that the positive oil price shocks are more important than negative shocks. Therefore, two policy responses can be considered: either sustaining the fixed exchange rate regime and following an economic diversification policy or switching towards a flexible exchange rate regime to achieve price stability. In that case, the existence of a stable money demand function in Saudi Arabia is a necessary precondition for adopting a monetary policy strategy targeted to price stability using instruments like money targeting.     

The monetary economics of Jules Dupuit

This paper analyses Dupuit's views on money, bimetallism, free banking and credit. By means of textual and contextual analysis, I argue that Dupuit endorsed the quantity theory based on the neutrality of money. For him, the value of money was determined by supply and demand. The only exception concerned the redistributive effects of gold between trading nations. Dupuit's approach to credit and his views on the issuance of banknotes were distinct from those of most French liberals. He did not consider credit to be capital, and he warned against the overissue of banknotes.     

Rationality of liquidity preferences and the neoclassical monetary growth model

In the neoclassical monetary growth literature, the rationality condition in the sense of freedom from money illusion is imposed on the demand for nominal balances by assuming that this demand is homogenous of degree one in nominal income and nominal wealth. We argue that the price level should enter into this demand as a separate argument, and that the rationality condition should require that the demand be homogenous of degree one in nominal income, nominal wealth, and the price level. Then, the symmetry issue of the real purchasing power is consequential to the structure of the neoclassical monetary growth model.

Monopoly with local knowledge of demand function

In this note, we propose a model where a quantity setting monopolist has incomplete knowledge of the demand function. In each period, the firm sets the quantity produced observing only the selling price and the slope of the demand curve at that quantity. Given this information and through a learning process the firm estimates a linear subjective demand curve. We show that the steady states of the dynamic equation are critical points of the objective profit function. Moreover, results depend on convexity/concavity of the demand. When the demand function is convex and the objective profit function has a unique critical point: the steady state is a globally stable maximum; conversely when then steady state is not unique, local maximums are locally stable, while local minimums are locally unstable. On the other hand when the demand function is concave, the unique critical point is a maximum: there can be stability or instability of the critical point and period two cycles around it via a flip bifurcation. Moreover, through simulations we can observe that, with a mixed inverse demand function, there are different dynamic behaviors, from stability to chaos and that we have transition to complex dynamics via a sequence of period-doubling bifurcations. Finally, we show that the same results can be obtained if the monopolist is a price setter.     

Determinants and Forecast of Price Level in India: a VAR Framework

The theoretical association of money supply and exchange rates with prices has been empirically established and shown to be dominant in explaining changes in price levels in India. However, post liberalisation, studies have shown price levels to be impacted by several other factors as also, weakened influence of the traditional factors established by theories. This study aims to find the determinants of price level for the period 1994–2008 using a Vector Autoregression model and test the predictive ability of the model. Our results show shorter and smaller impact of change in money supply and nominal effective exchange rate on price levels. Both money supply and nominal effective exchange rates are found to Granger-cause Consumer Price Index. But, impulse response functions show that the impact of shocks from money supply and nominal effective exchange rates on consumer prices peaks after two lags and is short-lived. Forecast error variance decomposition shows that these demand side factors contribute only 6 % of the forecast error variation in Consumer Price Index.
