Fiscal deficits and inflation

Macroeconomic theory postulates that persistent fiscal deficits are inflationary. Yet empirical research has had limited success in uncovering this relationship. This paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory. Unlike previous studies, we model inflation as non-linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic, using panel techniques that explicitly distinguish between short- and long-run effects of fiscal deficits. Results spanning 107 countries over 1960-2001 show a strong positive association between deficits and inflation among high-inflation and developing country groups, but not among low-inflation advanced economies.     

The New Keynesian Phillips Curve: From Sticky Inflation to Sticky Prices

The New Keynesian Phillips Curve (NKPC) model of inflation dynamics based on forward-looking expectations is of great theoretical significance in monetary policy analysis. Empirical studies, however, often find that backward-looking inflation inertia dominates the dynamics of the short-run aggregate supply curve. This inconsistency is examined by investigating multiple structural changes in the NKPC for the U.S. between 1960 and 2005, employing both inflation expectations survey data and a rational expectations approximation. We find that forward-looking behavior plays a smaller role during the high and volatile inflation regime to 1981 than in the subsequent period of moderate inflation, providing empirical support for sticky price models over the last two decades. A break in the intercept of the NKPC is also identified around 2001 and this may be associated with U.S. monetary policy in that period.     

Reconsidering the Relationship between Inflation and Relative Price Variability

It has long been popularly believed that the relationship between inflation and relative price variability (RPV) is positive and stable. Using disaggregated CPI data for the United States and Japan, however, this study finds that the relationship is neither linear nor stable over time. The overall relationship is approximately U‐shaped around a nonzero threshold inflation rate. RPV therefore changes not with the inflation rate per se, but with the deviation of inflation from the threshold inflation rate. More importantly, the relationship is by no means stable over time but instead varies significantly in a way that coincides with regime changes of inflation or monetary policy. The relationship was positive during the period of high inflation of the 1970s and the early 1980s, as has been documented by a number of previous studies, whereas it takes a U‐shape profile during the Great Moderation. The results are robust to the use of core inflation, which excludes the traditionally volatile prices of food and energy. This paper then presents a modified version of the Calvo‐type sticky price model to describe the observed empirical regularities. Simulation experiments show that the modified Calvo model fits the data well, and that the underlying relationship hinges upon the degree of price rigidity, which is systematically related to inflation regime. For countries and periods with low inflation rates, the relationship takes a U‐shape as price adjustment is more sticky. In a high‐inflation environment, when price setting becomes more flexible, the U‐shaped profile vanishes.     

Common stock returns,real activity,money, and inflation: Some international evidence

This paper tests whether the negative relationship between real stock returns and inflation in the United States is in fact proxying for a positive relationship between stock returns and real activity variables in six major industrial countries over 1966–1979. Consistent with Fama's ‘proxy-effect’ hypothesis, we document a negative relationship between inflation and real activity and a positive one between real stock returns and real activity variables. Real activity variables dominate money growth rates and expected and unexpected inflation in explaining real stock returns. A puzzling result that still remains is the positive role of money and the negative role of expected inflation in explaining these real stock returns in all major industrial countries.     

Reconsidering the natural rate hypothesis in a New Keynesian framework

This paper formulates a stylized New Keynesian model in which each individual firm can select the frequency of its price adjustments. The endogeneity of contract duration has a dramatic impact on the magnitude of the aggregate effects of steady-state inflation. With a plausible calibration of the magnitude of menu costs and other structural parameters, this model predicts a relationship between steady-state inflation and the frequency of price adjustment that is reasonably close to the empirical findings of cross-country studies. Furthermore, at moderate inflation rates, steady-state inflation generates relative price distortions that have a non-trivial impact on aggregate output, but this impact wanes and eventually disappears at much higher annual inflation rates because the frequency of price adjustment approaches that of the flexible-price economy.     

Time Aggregation and the Relationship between Inflation and Money Growth

Using panel data for 99 countries, we confirm that the measured elasticity of prices with respect to money is higher, and closer to unity, the higher is money growth and the longer the time horizon over which the data are averaged. We propose two explanations. In one, the true model of inflation involves a lagged response to money growth. In the other, there is negative correlation between shocks to inflation and money growth. Our empirical results can be explained if high–money‐growth countries have (i) shorter lags or (ii) less negative correlation, when compared to countries with low money growth.     

Inflation and openness in India: an asymmetric approach

This paper examines the dynamic relationship between inflation and openness from 1970 to 2014 in the Indian context. In the first of its kind, this paper investigates the relationship within a nonlinear framework by employing NARDL cointegration test due to Shin, Yu, and Greenwood Nimmo (2014). The empirical results show that there is asymmetry in the relationship between openness and inflation both in short-run as well as in long-run. However, overall a positive relation (though weak) holds between inflation and openness and hence refutes well known Romer (1993) hypothesis that inflation falls with openness. The results further showed a positive relation between inflation and other variables in the study. The overall response of inflation towards the positive and negative changes in explanatory variables differed significantly.     

通货膨胀的门限效应与金融—经济增长关系——基于中国数据的经验研究

在探讨金融与经济增长关系的研究中,一个重要的研究问题就是金融发展与经济增长之间关系是否取决于通货膨胀的水平。基于门限效应回归模型,本文利用中国1952年至2008年的年度数据将通货膨胀作为门限变量进行了实证研究。研究结果表明金融发展与中国的经济增长之间存在着统计意义上显著的非线性关系,通货膨胀处于门限值以下金融发展促进经济增长,而通货膨胀超过门限值金融发展则不再显著地促进经济增长。这启示我们强调金融发展的增长效应时,政策制定者需要将通货膨胀率保持在其发生结构性变化水平以内。     

Interwar Inflation,Unexpected Inflation,and Output Growth

Interwar macroeconomic history is a natural place to look for evidence on the correlation between output growth and inflation or unexpected inflation. We apply time‐series methods to measure unexpected inflation for more than 20 countries using both retail and wholesale prices. There is a significant, positive correlation between output growth and inflation for the entire period. There is little evidence that this correlation is caused by an underlying role for unexpected inflation. For wholesale price inflation in particular, the output declines associated with deflations were larger than the output increases associated with inflations of the same scale.     

Real Wage Rigidities and the New Keynesian Model

Most central banks perceive a trade-off between stabilizing inflation and stabilizing the gap between output and desired output. However, the standard new Keynesian framework implies no such trade-off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare-relevant output gap. In this paper, we argue that this property of the new Keynesian framework, which we call the divine coincidence , is due to a special feature of the model: the absence of nontrivial real imperfections. We focus on one such real imperfection, namely, real wage rigidities. When the baseline new Keynesian model is extended to allow for real wage rigidities, the divine coincidence disappears, and central banks indeed face a trade-off between stabilizing inflation and stabilizing the welfare-relevant output gap. We show that not only does the extended model have more realistic normative implications, but it also has appealing positive properties. In particular, it provides a natural interpretation for the dynamic inflation–unemployment relation found in the data.     

Regulation and the Neo-Wicksellian Approach to Monetary Policy

Laubach and Williams (2003) employ a Kalman filter approach to jointly estimate the neutral real federal funds rate and trend output growth using an IS relationship and an output-gap-based inflation equation. They find a positive link between these two variables, but also much error surrounding neutral real rate estimates. We modify their approach by including variables for regulations on deposit interest rates and on wages and prices. These variables are statistically significant and notably affect estimates of two policy-relevant coefficients: the sensitivity of output to the real interest rate and that of inflation to the output gap.     

Monetary policy and the twin crises

After presenting a brief overview of the recent financial crisis and the European debt crisis that followed in its wake, this paper goes on discuss monetary policy in the United States, the United Kingdom and the Euro bloc prior to and during the course of the two crises. The paper presents historical evidence for the three areas on the relationships linking the volatilities of output, inflation and monetary growth. In all three these relations are strongly positive. There is, therefore, no tradeoff between inflation and output volatility; the two move up and down together. Both, moreover, move up and down with the volatility of monetary growth. Viewed from this perspective, the increased volatilities of money supplies and the monetary base in the United States, the United Kingdom and the Euro bloc over the last half decade pose problems.     

The Time-Varying Phillips Correlation

We use complex demodulation techniques to investigate changes in the correlation between real activity and inflation at the business-cycle frequencies in the United States, the United Kingdom, the Eurozone, and 10 other Organization for Economic Cooperation and Development (OECD) countries over the post-WWII era. Consistent with the analysis of Ball, Mankiw, and Romer (1988) we document a positive correlation between the time-varying average gain of real activity onto inflation at the business-cycle frequencies and inflation's Hodrick-Prescott trend, which is compatible with New Keynesian theories emphasizing the link between trend inflation, the frequency of price adjustments, and the slope of the Phillips trade-off.     

Model Misspecification, the Equilibrium Natural Interest Rate, and the Equity Premium

This paper analyzes the natural rate of interest and the equity premium in a nonlinear model where agents are uncertain over both future technology growth and the future course of monetary policy. I show that model uncertainty, and notably uncertainty on the future course of monetary policy, can give rise to a sizable precautionary savings motive. This result is potentially problematic for both the estimation of the natural rate and its use as a policy indicator. Monetary uncertainty can also contribute to amplify the equity premium, and to account for its apparent, positive link with inflation.     

Commodity prices and inflation: Testing in the frequency domain

We provide evidence for a long term, positive relation between commodity prices and inflation. However, this is only detected when frequency dependency in the regression is statistically accounted for, suggesting nonlinear dynamics between the variables. We also test whether commodity prices can be used to forecast inflation. Again relying on frequency domain methods, we indeed find support for long term causality from commodities to inflation. Moreover, the information content of commodity futures prices is robust to the effects of several financial and economic variables.     

我国外汇市场压力研究——基于马尔可夫区制转换方法

本文基于1996~2010年月度数据,采用马尔可夫三区制转换模型对人民币外汇市场压力进行了区制识别,并考察了货币扩张、通货膨胀、外汇储备、经济增长及人民币名义有效汇率变动5个变量在不同区制及区制转换过程中的动态变化情况。实证结果表明,MSIH(3)-VAR(1)模型能较好识别人民币外汇市场压力区制,人民币外汇市场经历了适度升值压力区制、贬值压力区制及较强升值压力区制三个阶段;其中,外汇储备是外汇市场压力区制转变的关键因素,较强升值压力区制向其他两种区制转换过程中会伴随着汇率的升值和外汇储备的减少。     

Inflation Band Targeting and Optimal Inflation Contracts

In this paper we provide a theoretical treatment of how inflation target ranges cope with the time-inconsistency problem arising from incentives for the monetary policymaker to exploit the short-run trade-off between employment and inflation to pursue short-run employment objectives, as in a Barro-Gordon (1983) model. Inflation band targets are able to achieve many of the benefits that arise under practically less attractive solutions such as the conservative central banker and optimal inflation contracts. Our theoretical model also shows how an inflation targeting range should be set and how it should respond to changes in the nature of shocks to the economy.     

Real Effects of Money Growth and Optimal Rate of Inflation in a Cash‐in‐Advance Economy with Labor‐Market Frictions

This paper studies the consequences of labor‐market frictions for the real effects of steady inflation when cash is required for households' consumption purchases and firms' wage payments. Money growth may generate a positive real effect by encouraging vacancy creation and raising job matches. This may result in a positive optimal rate of inflation, particularly in an economy with moderate money injections to firms and with nonnegligible labor‐market frictions in which wage bargains are not efficient. This main finding holds for a wide range of money injection schemes, with alternative cash constraints, and in a second‐best world with preexisting distortionary taxes.     

The International Dimension of Inflation: Evidence from Disaggregated Consumer Price Data

We estimate the contribution of international common factors to the dynamics of price inflation rates of a cross-section of 948 CPI products in four OECD countries: United States, Germany, France, and United Kingdom. We find two main results. First, on average, and at least in the sample 1991–2004, one international common factor explains between 15% and 30% of the variance of consumer prices (depending on the transformation applied to the data). Given the high level of disaggregation of our panel, this estimate is best viewed as a lower bound for the contribution of international factors to inflation dynamics. Second, we find a strongly positive and statistically significant relationship between exposure of consumer inflation to international shocks and trade openness at the sectoral level. The latter result holds regardless of whether the original data are expressed in local as opposed to common currency.     

The implications of central bank transparency for uncertainty and disagreement

Using survey data from 25 economies we provide evidence that greater transparency surrounding monetary policy reduces uncertainty of interest rates and inflation, primarily by reducing uncertainty that is common to agents rather than disagreement between agents. This suggests that studies that focus on disagreement as a proxy for uncertainty understate the benefits of monetary policy transparency. The adoption of inflation targets and forward guidance are both associated with lower uncertainty, although inflation targets have a stronger impact on reducing uncertainty than forward guidance. Moreover, there are diminishing benefits from ever higher levels of transparency. Taken as a whole, our results support the contention that clarity of communication is as important as the magnitude of transparency.
