Variance-minimizing monetary policies with lagged price adjustment and rational expectations

This paper considers a macroeconomic model with rational expectations in which prices are incompletely flexible. Markets therefore fall to clear. In such a model monetary policy is not neutral. The variance of real and nominal quantities and interest rates is sensitive to the parameters of the feedback rule that determines the money supply. The monetary policy that achieves the goal of minimizing the steady-state variance of real output is characterized. We also examine monetary policies that are restricted in their generality and derive ‘second-best’ variance-minimizing feedback rules.     

Financial market imperfections and monetary policy strategy

In a model with imperfect money, credit and reserve markets, we examine if an inflation-targeting central bank applying the funds rate operating procedure to indirectly control market interest rates also needs a monetary aggregate as policy instrument. We show that if private agents use information extracted from money and financial markets to form inflation expectations and if interest rate pass-through is incomplete, the central bank can use a narrow monetary aggregate and the discount interest rate as independent and complementary policy instruments to reinforce the credibility of its announcements and the role of inflation target as a nominal anchor for inflation expectations. This study shows how a monetary policy strategy combining inflation targeting and monetary targeting can be conceived to guarantee macroeconomic stability and the credibility of monetary policy. Friedman's k-percent money growth rule, which can generate dynamic instability, and two alternative stabilizing feedback monetary targeting rules are examined.     

Markov-switching models,rational expectations and the term structure of interest rates

In order to evaluate the efficiency of the monetary transmission mechanism, we develop the formulas for testing rational expectations theory in the term structure of interest rates with VAR models of stochastically switching regimes in which all the parameters are regime dependent. These formulas are obtained for the strict version of rational expectations as well as for the case where measurement errors are assumed in the expectations relationship. They are extensible to other contexts that involve variables linked by rational-expectations behaviours. The testing procedure is implemented on interest rates of the Spanish inter-bank money market. Measurement errors must be assumed to find signs favourable to the theory.     

Taxation,rational expectations,and the neutrality of money

When progressive taxation of nominal income is introduced into a Barro-type monetary model with rational expectations, money may not be neutral even in the long run. In the short run, unanticipated money changes may cause output and prices to move either in the same or in opposite directions. The implications of this model are consistent with both the traditional inflation-output trade-off and the more recent phenomenon of “stagflation.”     

Price level determinacy and the choice of policy targets under rational expectations

We show that in a conventional macro model with rational expectations, the government can use monetary policy to peg real interest rates, and still attain a determinate price level provided it also pegs some nominal policy variable, e.g., nominal expenditures.     

Price rules, wage indexing, and optimal monetary policy

There has been a recent increased interest in a monetary price rule. This paper analyzes the efficiency of such a monetary rule within the context of a rational expectations macro model. We compare the price rule with the standard money rule and interest rate rule. We find that as the supply shock variance approaches zero the price rule dominates both a money and interest rate rule. We then investigate the efficiency of these alternative money rules when we allow wage indexation to the price level.     

Monetary policy and heterogeneous expectations

This paper studies the implications for monetary policy of heterogeneous expectations in a New Keynesian model. The assumption of rational expectations is replaced with parsimonious forecasting models where agents select between predictors that are underparameterized. In a Misspecification Equilibrium agents only select the best-performing statistical models. We demonstrate that, even when monetary policy rules satisfy the Taylor principle by adjusting nominal interest rates more than one for one with inflation, there may exist equilibria with Intrinsic Heterogeneity. Under certain conditions, there may exist multiple misspecification equilibria. We show that these findings have important implications for business cycle dynamics and for the design of monetary policy.     

Market‐Based Measures of Monetary Policy Expectations and Their Evolution Since the Introduction of the Euro

The paper considers the relation between monetary policy expectations and financial markets in the case of Europe. A number of money market instruments are compared, with the result that the 1‐month forward interest rates extracted from the Libor yield curve has the best prediction power of the future monetary policy path. These forward rates have been used to study the evolution of market expectations regarding the monetary policy of the European Central Bank (ECB). The sharp increases and the following decreases in interest rates during 2000–2001 have reduced the predictive power of money market instruments, but smoother management of interest rates and better communication from the ECB has helped to improve the forecasting power of money market instruments.     

Real and nominal effects of monetary policy shocks

Abstract.  We employ the identification scheme of Kahn, Kandel and Sarig (2002) to analyse the impact of Canadian monetary policy on ex ante real interest rates and inflationary expectations. First, we decompose nominal interest rates into ex ante real rates and inflationary expectations using the methodology of Blanchard and Quah (1989) . Then we estimate a recursive VAR model with innovations in a monetary aggregate and the overnight target interest rate as alternative measures of monetary policy shocks. We find that a negative policy shock raises both nominal and ex ante real interest rates, lowers inflationary expectations and real industrial output, and appreciates the Canadian dollar.     

The vanishing role of money in the macro-economy: An empirical investigation for India

The recent de-emphasizing of the role of “money” in both theoretical macroeconomics as well as in the practical conduct of monetary policy sits uneasily with the idea that inflation is a monetary phenomenon. Empirical evidence has, however, been accumulating pointing to an important leading indicator role for money and credit aggregates with respect to long term inflationary trends. Such a role could arise from monetary aggregates furnishing a nominal anchor for inflationary expectations, from their influence on the term structure of interest rates and from their affecting transaction costs in markets. Our paper attempts to assess the informational content role of money in the Indian economy by a separation of these effects across time scales and frequency bands, using the techniques of wavelet analysis and band spectral analysis respectively. Our results indicate variability of causal relations across frequency ranges and time scales, as also occasional causal reversals.     

Asymmetric information, financial intermediation, and business cycles

Summary. This incorporates a debt contracting problem with asymmetric information into a standard monetary business cycle model. The model incorporates a limited participation assumption in order to induce a liquidity effect of monetary shocks and propagate monetary disturbances. The model economy shows that a positive money supply shock generates a decrease in nominal interest rates and an increase in output level. Asymmetric information amplifies the response of capital to the money supply shock, but does not propagate them in other ways. When the monetary shock is an innovation in reserve requirements, it induces a persistent response of the economy. Received: March 20, 1998; revised version: 1 April 1998     

The nominal rate of interest, the rate of return on money, and inflationary expectations

This paper offers two modifications to the standard comparative-static analysis that help explain why nominal interest rates may either over- or under-adjust to a change in inflationary expectations, even in full general equilibrium: the inclusion of the real rate of return to money balances in commodity demand functions, and the presence of differing costs of obtaining information. In brief, the first factor may explain why nominal interest rates could over-adjust to a change in inflationary expectations, while the second may substitute for real balance effects in limiting the upward adjustment of nominal rates.     

Nominal uniqueness and money non-neutrality in the limit-price exchange process

We define continuous-time dynamics for exchange economies with fiat money. Traders have locally rational expectations, face a cash-in-advance constraint, and continuously adjust their short-run dominant strategy in a monetary strategic market game involving a double-auction with limit-price orders. Money has a positive value except on optimal rest-points where it becomes a ??veil?? and trade vanishes. Typically, there is a piecewise globally unique trade-and-price curve both in real and in nominal variables. Money is not neutral, either in the short-run or long-run and a localized version of the quantity theory of money holds in the short-run. An optimal money growth rate is derived, which enables monetary trade curves to converge towards Pareto optimal rest-points. Below this growth rate, the economy enters a (sub- optimal) liquidity trap where monetary policy is ineffective; above this threshold inflation rises. Finally, market liquidity, measured through the speed of real trades, can be linked to gains-to-trade, households?? expectations, and the quantity of circulating money.     

EQUILIBRIUM GROWTH IN A MONETARY ECONOMY WITH TRANSACTIONS COSTS*

The paper describes a dynamic general equilibrium monetary economy with technological primitives that are consistent with the possibility of asymptotic equilibrium growth. The paper focuses on the relationship between equilibrium financing constraints on investment goods, transaction costs and economic growth. A generalized growth condition is derived that involves both monetary growth rates and transaction costs. The condition is used to show that (i) although inflation taxes can potentially exert a negative influence on long-run economic growth, these growth effects cannot in general be arbitrarily large; and (ii) for some monetary growth rates, money is superneutral in contrast to the models of Stockman and Abel. Numerical work indicates that although the welfare and growth effects of decreasing nominal interest rates from a benchmark are large, the costs associated with raising nominal interest rates from benchmark are not.     

Australian monetary growth and short-term nominal interest rates: an interest parity efficient markets approach

The relationship between monetary growth and nominal interest rates continues to attract considerable attention in the literature. Mishkin (1982) has found that, by explicitly imposing market efficiency in an interest rate model for the US, empirical analysis does not support the ‘Keynesian’ proposition that increases in monetary growth are associated with reductions in short-term rates. In this paper a similar theoretical structure is used but, unlike Mishkin, explicit account is taken of the fact that Australia's capital market is closely integrated with international money markets. Incorporating this into the interest rate model indicates there is some empirical support for the ‘Keynesian’ proposition in the Australian case. The analytical model also incorporates a measure of interest rate volatility to account for the risk premium present in the forward rate for 90 day bank bills.     

Rational expectations and the demand for money: A nonparametric approach

This paper tests the U.S. demand for money for evidence of the effect of rational expectations of the income and interest rate variables that enter as arguments into that function. The data employed are simple-sum and Divisia aggregates, and the nonparametric tests are of the identification and information orthogonality of the various monetary measures. The Akaike Criterion is used to distinguish among the alternative specifications. While non-rationality is the typical result, Divisia aggregates appear to be more “rational” than simple sum. There is evidence of mean-reversion in interest rates as well.     

Disinflation costs in China and monetary policy regimes

This paper investigates the real effects of a disinflationary policy in China, in which we conduct a disinflation experiment in a medium-scale New Keynesian model. We highlight two key features of China's economy: the relevance of money to monetary policy rules and household inequality. For the former, we consider two monetary policy regimes: an expanded Taylor rule with money and a money supply rule. For the latter, we take into account a share of the population that is limited in its ability to participate in assets markets. Our analysis suggests that a disinflation policy is more costly when the central bank controls the money supply than the case in which the nominal interest rate is the policy instrument. Our results are driven by the different impacts of disinflation on nominal and real interest rates under the two regimes.     

MONETARY TARGETING IN WEST GERMANY,HOLLAND, AND SWITZERLAND

Links between fluctuations in domestic money supplies and subsequent fluctuations in rates of real output have been less visible in Western Europe than in the United States. This paper discusses some of the causes and investigates the stability of the demand for money in West Germany, the Netherlands and Switzerland. In all three countries, temporary changes in short-term interest rates temporarily affect the demand for money. These temporary changes in the demand for money are reflected in temporary blips in the monetary statistics, as agents substitute among various monetary assets. The hypothesis that aggregate demand responds only to longer-lasting changes in interest rates is tested by a two-step procedure. First, the official data on European money supplies are corrected for temporary disturbances caused by temporary changes in domestic interest rates. Second, changes in real activity are regressed on a measure of monetary stimulus, which takes into account the correction for temporary disturbances. This two-step procedure avoids some of the bias present in ordinary estimates of the demand-for-money function. The results show that the links between changes in money and subsequent changes in output are somewhat more tenuous in West Germany, the Netherlands, and Switzerland than in the U.S. but significant effects do exist. These effects are more easily documented when corrected time series for the European money supplies are used.     

Monetary policy in open economies

The recent literature on monetary policy in open economies has produced a strong presumption in favor of activistic policy and flexible exchange rates. We argue that this result may owe much to the combination of two commonly made assumptions: That nominal goods prices are rigid. And that the monetary authorities have a lot of information about the economy. When the source of nominal rigidity is found in wages and monetary policy is conducted according to less information demanding rules (such as a standard interest rate rule) policies that stabilize the money supply or the nominal exchange rate may perform better.     

Labour markets, liquidity, and monetary policy regimes

Abstract.  We develop an equilibrium model of the monetary policy transmission mechanism that highlights information frictions in the market for money and search frictions in the labour market. The information friction increases the persistence in the response of interest rates following monetary policy regime shifts. This occurs because agents have incomplete information about the nature of the shifts and optimally update their inflation forecasts using an 'adaptive' expectations rule. The search friction transmits the interest rate movements to the labour market by affecting job creation activities; together, the two frictions imply that unemployment reacts very gradually to monetary policy shocks.
