Estimating the Bank of Mexico’s reaction function in the last three decades: A Bayesian DSGE approach with rolling-windows

This paper uses a small open economy Dynamic Stochastic General Equilibrium (DSGE) model to investigate how Mexico’s central bank has conducted its monetary policy in the period 1995–2019. The main objective of the paper is to document the systematic changes in the Bank of Mexico’s reaction function by analyzing possible shifts in the parameters of the policy rule. The central bank’s policy is modeled using a Taylor rule that relates the nominal interest rate to output, inflation, and the exchange rate. I employ Bayesian computational techniques and conduct rolling-window estimations to explicitly show the transition of the policy coefficients over the sample period. Furthermore, the paper examines the macroeconomic implications of these changes through rolling-window impulse–response functions. The results suggest that the Bank of Mexico’s response to inflation has been steady since 1995, while the response to output and the exchange rate has decreased and stabilized after 2002.     

Emerging Markets, Unemployment and Inflation

World inflation is being held down by emerging market competition interacting with continuing OECD monetary policy. Here at home, fast productivity growth makes the UK something of an emerging market within Europe.     

What is the globalisation of inflation?

This paper studies the globalisation of CPI inflation by analysing core, energy and food components, testing for structural breaks in the relationships between domestic inflation and a corresponding country-specific foreign inflation series at the monthly frequency for OECD countries. The iterative methodology employed separates coefficient and variance breaks, while also taking account of outliers. We find that the overall pattern of globalisation in aggregate inflation is largely driven by convergence of the mean levels of the core component from the early 1990s, compatible with the introduction of inflation targeting in many countries of our sample. There is less evidence of increased synchronisation of shortrun movements in core than aggregate inflation, but an increased role for shortrun foreign energy inflation often contributes to the globalisation effect.     

Inflation Uncertainty, Output Growth Uncertainty and Macroeconomic Performance

We use a bivariate generalized autoregressive conditionally heteroskedastic (GARCH) model of inflation and output growth to examine the causality relationship among nominal uncertainty, real uncertainty and macroeconomic performance measured by the inflation and output growth rates. The application of the constant conditional correlation GARCH(1,1) model leads to a number of interesting conclusions. First, inflation does cause negative welfare effects, both directly and indirectly, i.e. via the inflation uncertainty channel. Secondly, in some countries, more inflation uncertainty provides an incentive to Central Banks to surprise the public by raising inflation unexpectedly. Thirdly, in contrast to the assumptions of some macroeconomic models, business cycle variability and the rate of economic growth are related. More variability in the business cycle leads to more output growth.     

From inflation to exchange rate targeting: Estimating the stabilization effects for a small open economy

This paper attempts to estimate possible losses in macroeconomic stabilization due to a move from inflation to exchange rate targeting on the example of the Czech Republic. The authors use an estimated New Keynesian policy model, typical inflation and exchange rate targeting rules, and representative central bank loss functions to carry out these estimations. The authors find that for the Czech Republic, moving from the historically applied inflation targeting to optimized exchange rate targeting should not involve any significant losses in macroeconomic stabilization. However, the Czech National Bank could improve its stabilization outcomes while remaining an inflation targeter. This requires the Czech National Bank to respond more strongly to increasing expected future inflation and to be less concerned about an opening output gap when adjusting its policy rate. Moving then from such optimized inflation targeting to optimized exchange rate targeting can result in significant losses in economic stabilization in the magnitude of 0.4–2% points of GDP growth.     

Gender differences in macroeconomic expectations: evidence from Turkey

The aim of this study is to examine how men and women’s expectations differ about macroeconomic outlook. We examine whether there exist similarities or differences in men and women’s macroeconomic expectations. For this paper, 365 of Turkey’s leading business economists, strategists, portfolio managers and industry managers participated in a survey titled “Economic Expectations in Turkey for 2010.” The survey investigates gender differences in regards to four macroeconomic expectations; namely, inflation, unemployment, growth and exports. The survey participants are first classified according to their gender, and then their economic perceptions are analyzed. Initially, Kolmogorov–Smirnov statistics are implemented to test normality of data. Then, the Chi-square test of independence is used to compare macroeconomic expectations of men and women. The empirical findings show that macroeconomic expectations of males and females are not statistically different for inflation, unemployment, and exports. On the other hand, macroeconomic expectations of males and females are statistically different only for economic growth at a 10% level. The results indicate that gender is not one of the main determinants for macroeconomic expectations.     

Bank competition,financial development and macroeconomic stability: Empirical evidence from emerging economies

In this study, we investigate the potential contribution of bank competition to macroeconomic stability, and the interactive role of financial development. We classify macroeconomic stability into economic and financial stability. Economic stability is represented by the volatility of actual and unexpected output growth, whereas financial stability is assessed by the aggregate Z-score and volatility of the private credit-to-gross domestic product ratio. We employ two structural and two non-structural measures of bank competition in our analysis. Applying a two-step dynamic panel system (GMM) to macroeconomic data from 48 developing nations from 1999 to 2018, we find a bell-shaped relationship between bank competition and macroeconomic stability. The findings imply that a higher level of bank competition promotes macroeconomic stability by reducing output growth volatility, fluctuations in private credit, and the probability of bank default. There is an optimal level of bank competition beyond which it may foster economic and financial instability. Moreover, financial development enhances bank competition’s positive impact on macroeconomic stability.     

The impact of monetary policy in the midst of big shocks

This paper studies the impact of Federal Reserve policies that created the largest deviations from price stability during the Fed׳s first 100 years: the post-World War I deflation, the deflation of the Great Depression, the inflation of World War II, and the Great Inflation of the 1970s. In terms of their macroeconomic impacts, I find that deflation was uniquely depressing in the 1930s because of cartel policies that prevented nominal prices and wages from adjusting to clear markets, and not because deflation is generically depressing. I find that the biggest impact of monetary policy during World War II was in debasing debt through inflation. I find that the main drivers of the 1970s economy were long-run changes in productivity and the labor market, and that there may have been little that the Fed could have done at this time to expand employment and output. More broadly, I find that macroeconomic performance would have been better over the Fed׳s first century had the Fed followed a monetary policy to deliver stable prices.     

Trend growth and learning about monetary policy rules

The paper examines the effect of trend productivity growth on the determinacy and learnability of equilibria under alternative monetary policy rules. Under zero trend inflation we show that the economic structure is isomorphic to that of Bullard and Mitra (2002) and show that under a policy rule that responds to current period inflation and output a higher trend growth rate relaxes the conditions for determinacy and learnability. Results are mixed for other policy rules. Under the expectations-based rule, trend growth tightens the conditions for determinacy but it relaxes the conditions for learnability. Under the lagged-data-based rule, trend growth tightens the conditions for determinacy and learnability. Our analysis shows that lower (higher) trend growth has similar effects as higher (lower) trend inflation in the sense of making inflation more (less) forward-looking. Thus, our results complement previous studies on the role of high trend inflation as a cause of macroeconomic volatility in the U.S. in the 1970s, as this period was also characterized by productivity growth slowdown.     

Some empirical evidence on the real effects of nominal volatility

It has been argued that volatility in nominal macroeconomic aggregates has had a negative effect on real output, in particular that such volatility contributed to slow output growth in the early 1980s. This paper reexamines the effects of volatility in nominal macroeconomic aggregates in the context of a modern simultaneous equation framework where the volatility of, nominal macroeconomic variables is modeled as the conditional variance of two variables of interest: the federal funds rate and inflation. The empirical framework is the recently developed multivariate GARCH-in-mean vector autoregressive model. We confirm evidence that inflation volatility and tight monetary policy have directly affected output growth, but find that volatility in the federal funds rate has not.     

Defining efficient policies in a general equilibrium model: a multi-objective approach

Macroeconomic policy makers are typically concerned with several indicators of economic performance. We thus propose to tackle the design of macroeconomic policy using Multicriteria Decision Making (MCDM) techniques. More specifically, we employ Multi-objective Programming (MP) to seek so-called efficient policies. The MP approach is combined with a computable general equilibrium (CGE) model. We chose use of a CGE model since it has the dual advantage of being consistent with standard economic theory while allowing one to measure the effect(s) of a specific policy with real data. Applying the proposed methodology to Spain (via the 1995 Social Accounting Matrix) we first quantified the trade-offs between two specific policy objectives: growth and inflation, when designing fiscal policy. We then constructed a frontier of efficient policies involving real growth and inflation. In doing so, we found that policy in 1995 Spain displayed some degree of inefficiency with respect to these two policy objectives. We then offer two sets of policy recommendations that, ostensibly, could have helped Spain at the time. The first deals with efficiency independent of the importance given to both growth and inflation by policy makers (we label this set: general policy recommendations). A second set depends on which policy objective is seen as more important by policy makers: increasing growth or controlling inflation (we label this one: objective-specific recommendations).     

INFLATION ECONOMICS: THE HEATH–BARBER BOOM, 1972–74

The UK macroeconomic boom of the early 1970s is an experiment that refutes the notion of cost–push inflation. However, such nonsense endures as the consequence of two factors. The first is the convenient ruse by which the state ducks its responsibility for monetary inflation and points the finger in other directions. The second is a potential to confuse the source of an individual price increase (rising scarcity) and the source of general price increases (excessive money).     

Macroeconomic forecasting and structural change

The aim of this paper is to assess whether modeling structural change can help improving the accuracy of macroeconomic forecasts. We conduct a simulated real‐time out‐of‐sample exercise using a time‐varying coefficients vector autoregression (VAR) with stochastic volatility to predict the inflation rate, unemployment rate and interest rate in the USA. The model generates accurate predictions for the three variables. In particular, the forecasts of inflation are much more accurate than those obtained with any other competing model, including fixed coefficients VARs, time‐varying autoregressions and the naïve random walk model. The results hold true also after the mid 1980s, a period in which forecasting inflation was particularly hard. Copyright © 2011 John Wiley & Sons, Ltd.     

What Drives Output Volatility? The Role of Demographics and Government Size Revisited

This paper studies the determinants of output volatility in a panel of 22 OECD countries. In contrast to the existing literature, we avoid ad hoc estimates of volatility based on rolling windows, and we account for possible non‐stationarity. Specifically, output volatility is modelled within an unobserved components model where the volatility series is the outcome of both macroeconomic determinants and a latent integrated process. A Bayesian model selection approach tests for the presence of the non‐stationary component. The results point to demographics and government size as important determinants of macroeconomic (in)stability. A larger share of prime‐age workers is associated with lower output volatility, while higher public expenditure increases volatility.     

Understanding survey-based inflation expectations

This paper examines the behavior of inflation expectations in the United States. After documenting deviations from rationality in survey-based inflation expectations, I apply a model selection algorithm, boosting, to the inflation expectations of households and professionals. The algorithm builds a regression-like model of expected inflation using a large panel of macroeconomic data as possible covariates. The algorithm achieves a very strong fit in-sample, and finds that the inflation expectations of households correlate with different macroeconomic variables from the expectations of professionals. However, it is difficult to exploit the predictability of inflation expectations in order to improve forecasts of the realized inflation.     

Impact of macroeconomic surprises on the Brazilian yield curve and expected inflation

This study investigates how unexpected announcements in Brazilian and U.S. macroeconomic indicators affect the term structure of nominal interest rates, as well as implicit inflation expectations and real interest rates. Using daily data from March 2005 to December 2012, we employ an extended Vector Error Correction Model to take into account nonstationarity and the long-term equilibrium among different maturities of those curves. We found empirical evidence that macroeconomic surprises, domestic (Brazilian) and external (U.S. American), which lead the market to believe that there might be a higher risk of inflation or an overheated economy, raise nominal interest rates, implicit expected inflation and real interest rates. Surprisingly, in relation to the efficient-market hypothesis, we found that some macroeconomic surprises have a lagged effect on the yield curves. We also tested the impact of the global financial crisis of 2007–09 and found that the crisis affected significantly the direction and magnitude of the responses to macroeconomic news.     

WORLD OUTLOOK

The recent weakness of the world economy does not undermine the relatively optimistic forecast for 1987 which we presented in May. At that time we suggested that activity would be sluggish for most of this year as a result of the impact effect of the OPEC III oil price collapse. But we also argued that by the end of the year there would be clear signs of a consumer-led recovery as the personal sector adjusted to the real income gains and lower inflation benefits of the lower oil price and the reduction in nominal interest rates which followed. There is mounting evidence of rising consumer spending, particularly in Europe and it is something of a puzzle that output has not risen to meet this demand. The explanation is partly that producer confidence has lagged behind that of consumers, so that demand has been met from stock, and partly that spending has been supplied from countries outside the OECD, especially the NICs in the Far East. Nevertheless, we are convinced that our earlier view of OECD output prospects next year remains the most likely though, in recognition of the growing importance of non-OECD competition, we have adjusted the output forecast down slightly. OECD GNP is expected to rise 2.6 per cent this year, with an acceleration to over 4 per cent in 1987 arid 1988. Moreover, we believe this can be achieved without a rebound in inflation, which is forecast to be stable at about its present level of 2 1/2 per cent.     

The Impact of the 2008 Crisis on UK Prices: What We Can Learn from the CPI Microdata1

This paper takes the locally collected price quotes used to construct the CPI index in the UK for the period 1996–2013 and explores the impact of the Great Recession (2008-9) on the pricing behaviour of firms. We develop a time series framework which captures the link between macroeconomic variables and the behaviour of prices in terms of the frequency of price change, the dispersion of price levels and the size, dispersion and kurtosis of price-growth. We find strong evidence for inflation having an effect, but not output. The change in the behaviour of prices during the Great Recession is largely explained by the changes in inflation and VAT. Nevertheless, the magnitude of the inflation effect is sufficiently small that it need not influence monetary policy.     

The Influence and Policy Signalling Role of FOMC Forecasts

Federal Open Market Committee (FOMC) policymakers have published macroeconomic forecasts since 1979 and we examine the effects of FOMC inflation forecasts using a structural VAR model. First, we assess whether they influence private inflation expectations. Second, we investigate the underlying mechanism at work and whether they convey policy signals. We provide original evidence that FOMC inflation forecasts influence private ones. We also find that the influencing effect of FOMC forecasts does not come through current Fed rate changes, that FOMC forecasts affect private expectations in a different way than current policy decisions, and that FOMC forecasts are informative about future Fed rate movements.
