Money Growth,Output Growth,and Inflation: Estimation of a Modern Quantity Theory

This paper develops a long-run version of the quantity theory of money growth, real GDP growth, and inflation. Inflation rates, averaged for the years 1980-1993, are computed for 81 countries. These cross-section inflation rates are explained almost entirely by average M2 growth rates. In countries marked by high money growth and inflation, the estimated coefficients of M2 growth are strikingly close to one, strongly confirming the quantity theory. By contrast, in countries with relatively low money growth and inflation, the estimated money growth coefficient is only 0.69; the quantity theory offers a less complete explanation of inflation. Money growth and GDP growth are nearly orthogonal, consistent with long-run monetary superneutrality. The quantity theory is a reliable model of inflation for most countries, but not for those experiencing slow long-run money growth.     

Bertrand-Edgeworth equilibrium in a cash-in-advance economy

This paper is about price and wage competition in a dynamicgeneral equilibrium model. We consider an equity financed economywhere firms need money to finance their input costs. Part ofthe output is sold for money to be used in the next period asworking capital and the remaining part is distributed to ownersas real dividends. We first characterize the steady state competitiveequilibrium path. Second, we study whether this competitiveequilibrium can be supported as a pure strategy Nash equilibriumin price and wage setting games. We prove a positive resultfor price competition and a negative one for wage competition.     

Does Money Have a Role in Monetary Policy for Price Stability under Inflation Targeting in Thailand?

This paper deploys Thai quarterly data for the study period 1999q1–2014q4 to econometrically investigate the proposition that money growth is an important, if not the sole, determinant of inflation under inflation targeting and that the money growth-inflation relation is not conditional on the stability of the money-demand function. The autoregressive distributed-lag (ARDL) bounds-testing results suggest that, across the study period, the Thai money stock (narrow or broad), real output, prices, interest rates and exchange rates maintained a long-run equilibrium relationship. The associated error-correction model of inflation confirms the cointegral relationship among money (narrow or broad), real output, prices, interest rates and exchange rates. It also suggests that money growth has a significant distributed-lag impact on inflation. The presence of this money growth-inflation relationship was associated with a stable narrow money-demand function, whereas the broad money-demand function remained unstable. These results for the study period are consistent with the view that the causal relationship between money growth and inflation holds in Thailand under inflation targeting when the Bank of Thailand deploys a short-term policy interest rate, rather than a monetary aggregate, as the instrument of monetary policy and that this relationship is not conditional on the stability of the money-demand function.     

Bank Lending and Inflation in Malaysia: Assessment from Unrestricted Error-Correction Models

The paper estimates inflation models for Malaysia by considering the influence of bank lending. The unrestricted error-correction model (UECM) proposed in Pesaran et al. (2000) was employed as being appropriate for small sample analysis such as the present study which covered annual data from 1973 to 1997. The results of 'bounds' tests confirmed a long-run equilibrium relationship between inflation and its determinants, namely import price, money supply (M3), bank credit and real income. The estimated UECMs revealed that the important factors in the Malaysian inflation process are import price and real-income variables. It was found that concurrent fiscal policies had a major influence on the impact of the depreciation of the naira on inflation. The UECMs appear to perform well and to provide an appropriate framework for forecasting the Malaysian inflation behaviour.     

Inflation in South Africa: An Assessment of Alternative Inflation Models

We consider the relative empirical performance of a range of inflation models for South Africa. Model coverage is of Phillips curve, New Keynesian Phillips curve, monetarist and structural models of inflation. Our core findings are that the single most robust covariate of inflation is unit labour cost. We further decompose unit labour cost into changes in the nominal wage and real labour productivity. The principal association is a strong positive relationship between inflation and nominal wages, while improvements in real labour productivity report only a relatively weak negative association with inflation. Supply‐side shocks also consistently report an association with inflation. As to demand‐side shocks, the output gap does not return a robust statistical association with inflation. Instead, it is growth in the money supply and government expenditure which return robust and theoretically consistent associations with inflationary pressure.     

Does inflation matter for growth?

The interaction between inflation and economic growth is studied within a simple model incorporating money and finance into an optimal growth framework with constant returns to capital. The model includes the potential impact of inflation on growth, via (a) saving and real interest rates, (b) velocity and financial development, (c) the government budget deficit through the inflation tax and tax erosion, and (d) efficiency in production through the wedge between the returns to real and financial capital. The hypothesized effect of inflation on long-run growth through these channels is estimated by applying the random-effects panel model to two sets of unbalanced panel data side by side, from the Penn World Tables and from the World Bank, covering 170 countries from 1960 to 1992. The cross-country links between inflation and growth are economically and statistically significant and robust. Specifically, the results show that inflation in excess of 10–20 percent per year is generally detrimental to growth.     

Changes in world real interest rates and inflationary expectations

Changes in World Real Interest Rates and Inflationary Expectations. —One of the major macroeconomic puzzles has been that the real interest rates were persistently low in the seventies and persistently high in the eighties. The authors use a news framework to investigate the extent to which shocks in real output, money supply, world trade, oil prices, stock prices and expected inflation affect the world and national real interest rates. They find dominant effects on real interest rates from movements in expected inflation rates. This suggests the presence of persistent misperceptions about future inflation and the need of further research into the formation of inflationary expectations.     

Performance of Core Inflation Measures

This paper assesses the performance of core inflation measures based on the structural VAR approach. Since core or monetary inflation is not directly observable, we develop a monetary general equilibrium model that fits real aggregated European data and we use this model to generate time series for headline as well as core inflation. For five different schemes which attempt to identify core inflation within a VAR framework it is investigated whether the estimated core inflation series recover the true series sufficiently precise in order to be useful for monetary policy.     

LONG-RUN M3 DEMAND IN SOUTH AFRICA: A COINTEGRATED VAR MODEL

This paper presents a system cointegration analysis of a long‐run demand for money (measured in terms of M3) in South Africa. In particular, the paper estimates a cointegrated vector autoregression model, consisting of real money, income and the opportunity cost of holding money. Using a variety of theory consistent identification schemes, the money demand function is identified along with other two cointegrating relations, namely, an IS‐type relationship and a relationship relating inflation to the spread between long‐ and short‐term interest rates. The model shows that of the variables used, only income and real money are error‐correcting to the money demand relation. The money demand relation is found to be relatively stable over the sample period, when short‐run fluctuations are corrected for. The model further shows that the long‐run link between money and inflation is rather weak.     

Nominal versus real wage rigidity in a monopoly union: A synthesis

Based upon a monopoly union model, this paper addresses how the degree of money illusion of the union member and the indexation rule of unemployment benefits are interdependent in governing the possibility of either nominal or real wage rigidity. Two main findings emerge from the analysis. First, nominal wage rigidity is present unless union members are characterized by complete money illusion and the government does not adjust its nominal unemployment payments. Second, real wage rigidity holds if union members are free of money illusion and nominal unemployment benefits are fully indexed to either union-set wages or the product price.     

The link between output and contracts under hyperinflation

In the conventional Keynesian model, nominal wage contracts (acting as a friction) transmit monetary shocks to real variables. In contrast, the new classical or real business cycle theory claims that firms and workers ignore the behavior of the actual real wage and instead generate an efficient level of employment (hence, output) based on a shadow real wage. Using Brazilian data covering a period during which the economy suffered hyperinflation and wage contracts were indexed by the government, results show that these fixed nominal wage contracts did not generate a nonneutrality of money as proposed by the Keynesian model. Instead, results support the view that contracts cannot propagate nominal shocks.     

The liquidity effect in a flexible-price monetary model

This paper examines the impact of macroeconomic policy shocksin a flexible-price dynamic stochastic general equilibrium (DSGE)model with money. Rather than adopting a money supply rule,monetary policy is modelled as a central bank using a simpleinterest rate rule (Taylor rule). Without assuming price stickinessor frictions in financial markets, this model is found to accountfor liquidity effects, generate higher persistence in outputand inflation, and capture the positive unconditional cross-correlationsrelating inflation and output.     

Effect of Money Supply on Real Output and Price in China

Over the past 30 years, China has achieved remarkable long-term economic growth. Using quarterly data, we study the effects of money supply on real output and inflation in China between 1993 and 2008. To this end, we use money supply shocks afler filtering out the expected component of the money supply. Our findings provide evidence supporting the asymmetric effect of positive and negative money supply shocks on real output and inflation in China. That is, real GDP growth in China responds to negative money supply shocks but not positive money supply shocks. In addition, inflation responds to positive money supply shocks but not negative money supply shocks. We conclude that the People＇s Bank of China＇ s policy of steady monetary growth appears to be appropriate. Our study offers important policy implications for China.     

Variation in the Effects of Aggregate Demand Shocks: Evidence and Implications across Industrial Countries

Over a sample of nineteen industrial countries, more variable aggregate demand and/or higher mean inflation attenuates (augments) the effect of aggregate demand shocks on real output growth (wage and price inflation) while having no effect on the response of the real wage to such shocks. In all countries examined, aggregate demand shocks are positively (negatively) correlated with nominal variables (real output). Among explanations of the business cycle based on shocks to aggregate demand, this evidence favors the new Keynesian sticky wage explanation over the sticky price and the new classical imperfect information explanations.     

Multiple wage-bargaining systems in the single European currency area

Little attention in the EMU literature has been paid to theinteraction between central bank monetary rules and systemsof collective wage bargaining. Analytically and empirically,coordinated wage-bargaining systems respond with real wage restraintto non-accommodating monetary policy. Since wage determinationis dominated by collective bargaining in all the EMU memberstates and wage coordination within the member states has grownsince 1980, this is a topic of potential importance. In particular,the replacement of the Bundesbank, directly targeting Germaninflation, by a European Central Bank (ECB) targeting Europeaninflation will remove a major institutional support of wagerestraint in Germany. The consequences of this for EMU are workedout under two scenarios, that inflation expectations will begenerated by ECB monetary policy and that they will reflectGerman inflation outcomes. Possible institutional developmentsare discussed including government union bargains. The Bundesbankalso played a major role in maintaining fiscal rectitude: forunderlying structural reasons, therefore, it is possible thatGermany will move to a period of fiscal activism with wage restraintand low inflation purchased through social contract negotiations.     

Forward-looking agents and inflation in an oil-producing country: Evidence from Iran

A monetary model of inflation was estimated on the oil-producing country of Iran for the period 1984:1–2016:4. It was found that expectations are formed rationally and that agents are forward-looking and adjust their behavior based on changes in government expenditure. Consequently, it was found that higher fiscal variables result in lower price levels over the long run. A higher oil price leads to a lower price in the country but to a higher money supply and interest rate over the long run. Furthermore, a higher domestic interest rate results in a higher price level, while the reverse is true for a higher foreign interest rate. Another cause of inflation in Iran is the foreign price level. It was found that over the short run a higher growth of the real government expenditure results in a lower inflation rate in the country but a positive change in the foreign interest rate brings in a higher inflation rate.     

The information content of M3 for future inflation in the Euro area

The Information Content of M3 for Future Inflation in the Euro Area. — The information content of M3 for future inflation in the euro area is investigated from a number of perspectives. Our results confirm that a significant positive association exists between the real money gap and future inflation up to five to six quarters ahead. It is also shown that, although the extended P-star model outperforms the rival model in some respect, the hypothesis that no useful information is contained in rival evidence can be rejected.     

Coffee, money and inflation in Colombia

The purpose of this paper is to analyse the relationship between coffee, money, inflation and international competitiveness in Colombia. The basic hypothesis being investigated is that higher (lower) prices of coffee will tend to result, through the accumulation of international reserves, in higher (lower) inflation. In turn, this higher inflation will generate, for a given rate of devaluation of the nominal exchange rate, a reduction of the real exchange rate, with the consequent loss of competitiveness in the non-coffee tradable goods sector. A ‘Dutch-disease’ type of model is developed to discuss analytically the relationship between coffee prices, money creation and competitiveness in the short and long run. Empirical results for 1952–1980 are presented. These results support the hypothesis that there has been a positive relationship between the price of coffee, money creation and inflation in Colombia.     

MEASURING THE WELFARE COST OF INFLATION IN SOUTH AFRICA

In this paper, we estimate the long‐run equilibrium relationship between money balance as a ratio of income and the Treasury bill rate for the period of 1965:02 to 2007:01, and in turn use the relationship to obtain welfare cost estimates of inflation. Using the Johansen technique, we estimate a log‐log specification and a semi‐log model of the above relationship. Based on the fits of the specifications, we decided to rely more on the welfare cost measure obtained under the log‐log money demand model. Our estimates suggest that the welfare cost of inflation for South Africa ranges between 0.34% and 0.67% of GDP, for a band of 3‐6% of inflation. Thus, it seems that the South African Reserve Bank's current inflation target band of 3‐6% is not too poorly designed in terms of welfare.     

Navigating the trilemma: Capital flows and monetary policy in China

In recent years China has faced an increasing trilemma—how to pursue an independent domestic monetary policy and limit exchange rate flexibility, while at the same time facing large and growing international capital flows. This paper analyzes the impact of the trilemma on China's monetary policy as the country liberalizes its good and financial markets and integrates with the world economy. It shows how China has sought to insulate its reserve money from the effects of balance of payments inflows by sterilizing through the issuance of central bank liabilities. However, we report empirical results indicating that sterilization dropped precipitously in 2006 in the face of the ongoing massive buildup of international reserves, leading to a surge in reserve money growth.We also estimate a vector error correction model linking the surge in China's reserve money to broad money, real GDP, and the price level. We use this model to explore the inflationary implications of different policy scenarios. Under a scenario of continued rapid reserve money growth (consistent with limited sterilization of foreign exchange reserve accumulation) and strong economic growth, the model predicts a rapid increase in inflation. A model simulation using an extension of the framework that incorporates recent increases in bank reserve requirements also implies a rapid rise in inflation. By contrast, model simulations incorporating a sharp slowdown in economic growth such as that seen in late 2008 and 2009 lead to less inflation pressure even with a substantial buildup in international reserves.
