Money and the Welfare Cost of Inflation in an R&D Growth Model

This study analyzes the effects of inflation on R&D and innovation‐driven growth. In the theoretical section, we incorporate money demand into a quality‐ladder model with elastic labor supply and derive the following result. If the elasticity of substitution between consumption and the real money balance is less (greater) than unity, then R&D and the growth rate of output would be decreasing (increasing) in the growth rate of money supply. Quantitatively, decreasing inflation in the U.S. to achieve price stability improves social welfare, and the welfare gain is equivalent to at least 0.5% of annual consumption. In the empirical section, we use cross‐country data to establish a negative and statistically significant relationship between inflation and R&D.     

A Tale of Two Growth Engines: Interactive Effects of Monetary Policy and Intellectual Property Rights

How do intellectual property rights that determine the market power of firms influence the growth and welfare effects of monetary policy? To analyze this question, we develop a monetary hybrid endogenous growth model in which R&D and capital accumulation are both engines of long‐run economic growth. We find that monetary expansion hurts economic growth and social welfare by reducing R&D and capital accumulation. Furthermore, a larger market power of firms strengthens these growth and welfare effects of monetary policy through the R&D channel but weakens these effects through the capital‐accumulation channel. Therefore, whether the market power of firms amplifies or mitigates the welfare cost of inflation depends on the relative importance of the two growth engines. Finally, we calibrate the model using data in the United States and the Euro Area to quantitatively evaluate and compare the welfare cost of inflation in these two economies and find that the R&D channel dominates in both economies.     

The dynamics of economic growth,oil prices,stock market depth,and other macroeconomic variables: Evidence from the G-20 countries

This paper examines the linkages between economic growth, oil prices, depth in the stock market, and three other key macroeconomic indicators: real effective exchange rate, inflation rate, and real rate of interest. We employ a panel vector autoregressive model to test Granger causality for the G-20 countries over the period 1961–2012. A novel approach to this study is that we clearly demarcate the long-run and short-run relations between the economic variables. The results show a robust long-run economic relationship between economic growth, oil prices, stock market depth, real effective exchange rate, inflation rate, and real rate of interest. In the long run, real economic growth is found to respond to any deviation in the long-run equilibrium relationship that is found to exist between the different measures of stock market depth, oil prices, and the other macroeconomic variables. In the short run we find a complex network of causal relationships between the variables. While the empirical evidence of short-run causality is mixed, there is clear evidence that real economic growth responds to various measures of stock market depth, allowing for real oil price movements and changes in the real effective exchange rate, inflation rate, and real rate of interest.     

Maintaining low inflation: Money, interest rates, and policy stance

This paper presents a systematic empirical relationship between money and subsequent prices and output, using US, euro area and Swiss data since the 1960-1970s. Monetary developments, unlike interest rate stance measures, are shown to provide qualitative and quantitative information on subsequent inflation. The usefulness of monetary analysis is contrasted to weaknesses in modeling monetary policy and inflation with respectively short-term interest rates and real activity measures. The analysis sheds light on the recent change in inflation volatility and persistence as well as on the Phillips curve flattening, and reveals drawbacks in pursuing a low inflation target without considering monetary aggregates.     

Investigating M3 money demand in the euro area

Euro area monetary growth has exceeded its target since 2001. Likewise, recent empirical studies did not find evidence in favour of a stable long-run money demand function. In contrast to the bulk of the literature, we are able to identify a stable long-run money demand relationship. This result is obtained when the analysis is done without the short run homogeneity restriction between money and prices. The basic equation can be improved by allowing for asymmetric adjustment. In a low inflation environment, opportunity costs of holding money have decreased. Thus, the apparent monetary overhang is reconciled within standard models.     

New evidence on the monetary approach of exchange rate determination in Mexico 1994–2007: A cointegrated SVAR model

We provide empirical evidence supporting the validity of both short and long run versions of the Monetary Approach of Exchange Rate determination for the Mexican peso–U.S. dollar exchange rate from 1994 to 2007 using a cointegrated SVAR model. We estimate not only the long-run relationship, between the variables of the monetary model for the exchange rate, but also the very short run effects which have been often ignored in previous empirical work. We show that there are robust short and long-run relationships between the Mexican monetary aggregates and the exchange rate, which ultimately responds to what Bilson's variant of MAER predicts.     

Monetary and financial stability in the euro area: Pro-cyclicality versus trade-off

This paper investigates the nexus between monetary stability and financial stability. We examine, in the experience of EMU between 1994 and 2008, first, the response of the term structure of interest rates, share prices, exchange rates, property price inflation and the deposit–loan ratio of the banking sector (our proxies for financial stability) to changes in the consumer price level and ECB policy rate (our proxies for monetary stability); second, whether and to what extent lower inflation has caused share price stability and how ECB policy rate has reacted to inflation. Using a sign-restriction-based VAR approach, we find that there is a pro-cyclical relationship between monetary and financial stability in the long-run. With a positive inflation shock, we find on average a 2% estimated decline in share prices. This suggests that the interest rate instrument used for inflation targeting is conducive to financial stability.     

Monetary Policy in a Schumpeterian Growth Model with Vertical R&D Sectors

We explore the growth and welfare effects of monetary policy in a Schumpeterian economy with cash-in-advance (CIA)-constrained research and development (R&D) investment in both the upstream and downstream sectors. We show that the nominal interest rate can have an inverted-U relation with economic growth due to its effects on labor allocations between manufacturing and R&D and between the R&D sectors. Furthermore, aggregate R&D overinvestment is generally sufficient but not necessary for the Friedman rule of zero nominal interest rates to be suboptimal. Calibrated using data from U.S. manufacturing firms, our model features a positive welfare-maximizing nominal interest rate despite aggregate R&D underinvestment.     

欧洲中央银行货币政策绩效评价:1999～2005

欧洲中央银行(ECB)围绕价格稳定目标确立起其货币政策战略。自1999年EMU正式建立以来,ECB的这一战略是否取得了成功呢?本文采用1999￣2005年数据,首先借助HICP通胀率、通胀预期等指标分析ECB货币政策在控制短期和中长期通胀方面的成效;然后进一步分阶段描述ECB货币政策行为和通胀率等主要宏观指标的内在联系。本文认为欧元区近些年来的通胀率超标主要是负向供给冲击尤其是能源价格冲击的结果;从主要指标看,ECB的货币政策战略已经取得初步成功;但是欧元区未来经济走势将对ECB的货币政策提出更严峻的挑战。     

Money and inflation in the euro area: A case for monetary indicators?

This paper examines inflation indicators for the euro area by studying the relationship between inflation, output, money and interest rates, using data spanning 1980–2001. The central finding is that both the output gap and the real money gap (the difference between the real money stock and the long-run equilibrium real money stock) contain considerable information regarding future inflation. In contrast, the Eurosystem's money-growth indicator (the difference between nominal money growth and a reference value), the prominent “first pillar” in its monetary strategy, contains little information about future inflation, and no information beyond that contained in the output and real money gaps. The predictive performance of the output gap has improved compared to that in a previous version of this paper, most likely because of better estimation methods.     

The Transmission of International Shocks: A Factor-Augmented VAR Approach

The empirical literature on the transmission of international shocks is based on small -scale VARs. In this paper, we use a large panel of data for 17 industrialized countries to investigate the international transmission mechanism, and revisit the anomalies that arise in the empirical literature. We propose a factor augmented VAR (FAVAR) that extends the model in Bernanke, Boivin, and Eliasz (2005) to the open economy. The main results can be summarized as follows. First, the dynamic effects on the UK economy of an unanticipated fall of short-term interest rates in the rest of the world are: real house price inflation, investment, GDP and consumption growth peak after 1 year, wages peak after 2 years, and CPI and GDP deflator inflation peak during the third year. Second, a positive international supply shock makes the distribution of the components of the UK consumption deflator negatively skewed. Third, in response to a domestic monetary shock, we find little evidence of the exchange rate and liquidity puzzles and little evidence of the forward discount and price anomalies.     

Inflation and Innovation in a Schumpeterian Economy with North–South Technology Transfer

This study analyzes how inflation affects innovation and international technology transfer via cash‐in‐advance constraints on R&D. We consider a North–South quality‐ladder model that features innovative Northern R&D and adaptive Southern R&D. We find that higher Southern inflation causes a permanent decrease in technology transfer, a permanent increase in the North–South wage gap, and a temporary decrease in the Northern innovation rate. Higher Northern inflation causes a temporary decrease in the Northern innovation rate, a permanent decrease in the North–South wage gap, and ambiguous effects on technology transfer. Finally, we calibrate the model to China–U.S. data to perform a quantitative analysis.     

数量规则还是利率规则？——我国转型时期量价混合型货币规则的理论基础

本文对我国货币政策转型时期兼顾数量和价格的货币政策调控实践进行了深入的分析。在货币数量论和货币效用模型的基础上,从理论上阐明了货币数量规则与利率价格规则的等价关系,并构建了符合中国货币政策实践的数量与价格混合型货币政策规则。这对于更好地理解我国货币政策转型时期的量价混合型货币政策操作具有重要的理论和现实意义。相关推论表明,正是由于数量和价格混合型货币规则,在利率低于均衡水平的情形下,中国的货币增速并未引发恶性通胀;修正的物价稳定泰勒原理表明,利率调整幅度小于通胀变化仍能够实现物价稳定。对中国的经验分析支持了理论和推论结果。在利率市场化基本完成和流动性格局逆转的当下,货币政策价格调控方式转型的必要性和迫切性日益上升,转型的条件日趋成熟。     

Globalization, Macroeconomic Performance, and Monetary Policy

The paper argues that many of the exaggerated claims that globalization has been an important factor in lowering inflation in recent years just do not hold up. Globalization does, however, have the potential to be stabilizing for individual economies and has been a key factor in promoting economic growth. The paper then examines four questions about the impact of globalization on the monetary transmission mechanism and arrives at the following answers: (i) Has globalization led to a decline in the sensitivity of inflation to domestic output gaps and thus to domestic monetary policy? No. (ii) Are foreign output gaps playing a more prominent role in the domestic inflation process, so that domestic monetary policy has more difficulty stabilizing inflation? No. (iii) Can domestic monetary policy still control domestic interest rates and so stabilize both inflation and output? Yes. (iv) Are there other ways, besides possible influences on inflation and interest rates, in which globalization may have affected the transmission mechanism of monetary policy? Yes.     

Accounting for Trends in Productivity and R&D: A Schumpeterian Critique of Semi-Endogenous Growth Theory

This paper argues that long-run trends in R&D and TFP are more supportive of fully endogenous "Schumpeterian" growth theory than they are of semi-endogenous growth theory. The distinctive prediction of semi-endogenous theory that sustained TFP growth requires sustained growth of R&D input is not supported by co-integration tests and forecasting exercises, as TFP growth has been stationary even though the growth rate of R&D input has fallen three-fold since the early 1950s. In contrast, the prediction of Schumpeterian theory that sustained TFP growth requires a sustained fraction of GDP to be spent on R&D is not contradicted by similar tests.     

Real effects of anticipated and unanticipated money: Some problems of estimation and hypothesis testing

The paper addresses two issues that arise in estimation and testing of the real effects of anticipated and unanticipated money. First it is shown that identification of the effects of unanticipated (or unperceived) monetary growth on real output is possible only if the a priori restriction is imposed that monetary growth does not depend on unanticipated (or unperceived) output. Second, the existing empirical work of Barro and others does not allow for three known channels through which money can affect real variables. These are (1) past and present anticipations of future monetary growth (the inflation tax channel), (2) expectations of monetary growth in a given period conditioned at various preceding dates (the Fischer-Phelps-Taylor effect) and (3) past and present revisions in forecasts of future monetary growth. The presence of the first of these would mean that alternative open-loop monetary growth rules have real effects. The presence of the other two implies that monetary feedback rules can have real effects. Omission of the first channel can lead to biased estimates of the effects of past anticipated monetary growth. Potentially serious observational equivalence problems are associated with the other two.     

Optimal inflation policy

This paper considers the problem of optimal long-run monetary policy. It shows that optimal inflation policy involves trading off two quite different considerations. First, increases in the rate of inflation tax the holding of many balances, leading to a deadweight loss as excessive resources are devoted to economizing on cash balances. Second, increases in the rate of inflation raise capital intensity. As long as the economy has a capital stock short of the golden rule level, increases in capital intensity raise the level of consumption. Ignoring the second consideration leads to the common recommendation that the money growth rate be set so that the nominal interest rate is zero. Taking it into account can lead to significant modifications in the ‘full liquidity rule’. Interactions of inflation policy with financial intermediation and taxation are also considered. The results taken together suggest that inflation can have important welfare effects, and that optimal inflation policy is an empirical question, which depends on the structure of the economy.     

Monetary rules and the nominal rate of interest under uncertainty

The expected real rate of return on a nominal bond is shown to be equal to the real rate of interest plus a premium for systematic purchasing power risk. The particular monetary rule employed by the central monetary authority affects the entire joint distribution of inflation and aggregate real wealth. Thus, the monetary authority is able to influence the relationship between the real and nominal interest rate not only by affecting the expected rate of inflation but also by affecting the systematic purchasing power risk of fixed nominal claims.     

基于金融形势指数对我国货币政策效果非线性的实证研究

本文基于总需求方程缩减式构建包含利率、汇率、资产价格以及货币供给因素具有动态权重的金融形势指数FCI,将其作为信息变量纳入到线性和非线性泰勒规则中进行实证分析,结果表明拓展的前瞻性泰勒规则更能描述我国利率行为,利率能很好的反应金融形势而对产出和通胀反应不足。以通货膨胀率为转换变量对我国货币政策效果进行检验和估计表明泰勒规则是非线性的,存在LSR1模型的非线性形式,利率对通胀的反应是非对称的。对非线性进行拓展性研究表明当通胀达到一定程度时,利率和FCI指数才具有稳定关系。     

Do monetary indicators lead euro area inflation?

This paper assesses based on euro area data whether the strong in-sample long-run link between money growth and inflation that has been highlighted by a number of recent empirical studies is exploitable to predict inflation out of sample. The results from standard bivariate forecasting models suggest that no monetary (nor any other) single indicator significantly outperforms a simple benchmark forecast. The further analysis shows that it would be premature however to discard based on such evidence the usefulness of monetary (and all other) indicators. First, it is shown that based on judgemental adjustments to monetary indicators correcting for the effects of identifiable, persistent velocity shifts, it appears possible to significantly improve predictive ability in real time. Second, I find that a factor forecasting model combining monetary and economic indicators, which can be regarded as a generalized quantity theory- or two-pillar Phillips Curve-forecasting model, delivers a fairly good and stable forecasting performance.
