The optimal choice of central bank independence and conservatism under uncertainty

This paper examines the optimal monetary delegation arrangement of central bank independence and conservatism in the presence of uncertainty about the central bank’s output objective. We show that full independence is no longer optimal with uncertain central bank preferences, and that optimal delegation involves the choice of both independence and conservatism. Further, we find that the usual trade-off between independence and conservatism no longer necessarily holds. Consequently, high central bank independence may also require a high level of conservatism.     

Forward-looking monetary policy and anticipated shocks to inflation

This paper extends a standard New Keynesian model to describe the effects of anticipated shocks to inflation and forward-looking monetary policy. Using the data generated from this modified model suggests that overlooking these two factors in the standard Cholesky structural vector autoregressive identification scheme will generate a price puzzle. Furthermore, this paper demonstrates that failing to account for these two factors may result in significant estimates of two other explanations of the price puzzle—the cost channel of transmission of monetary policy and indeterminacy due to violation of the Taylor principle—even though neither features in the data generating process.     

Political influence,central bank independence and inflation in Africa: A comparative analysis

This paper develops a new de facto measure of central bank independence (CBI) based on two recent measures of the turnover rates of central bank governors introduced by Vuletin and Zhu (2011), complemented with measures of alliance with the government in power, captured by prior executive appointment, tribe proximity, and political party affiliation. Using 1980–2009 data from 13 countries from the CFA zone (a currency union) and 18 non-CFA countries, the new index is used to 1) examine whether CBI can help achieve price stability in Africa and 2) show how CBI affects African countries that are part of a monetary union. We find that higher turnover rates lead to higher inflation. Our results are robust to the decomposition of the turnover rates into premature removals and ally replacements. Furthermore, we find that for CFA zone countries, central bank autonomy has no effect on inflation and instead inflation is driven by other variables such as the fixed exchange rate regime or commodity price shocks.     

Timeless perspective versus discretionary policymaking when the degree of inflation persistence is unknown

One major strand in optimal monetary policy analysis considers the robustness of alternative policies under model uncertainty. Another has focused on the appropriate perspective for optimal monetary policy, namely discretion or the timeless perspective (TP). The paper bridges these two parallel lines of research by assessing the welfare consequences of both policy perspectives in the presence of misperceptions about the degree of intrinsic inflation persistence. Contrary to most standard results, discretion can be the more robust perspective, the reason being that the TP exploits the expectations channel. With misperceptions this leads to large deteriorations in welfare.     

The empirical validity of the New Keynesian Phillips curve using survey forecasts of inflation

This paper investigates the performance of the New Keynesian Phillips curve when survey forecasts of inflation are used to proxy for inflation expectations. Previous authors such as Brissimis and Magginas (2008) have applied survey measures of inflation expectations to the NKPC, and have concluded that these estimates are superior to those estimated using actual data on future inflation. However this approach employs the use of the labor income share as the proxy for real marginal cost, something which is highly problematic once we consider the countercyclicality of this variable. This paper develops and tests a procyclical marginal cost variable alongside various survey measures of inflation forecasts in the NKPC, while recognizing the problem of weak instruments that occurs when estimating the model using conventional GMM. We find that the NKPC produces a counter-intuitive negative and significant coefficient on procyclical marginal cost when surveys of inflation forecasts are used, which casts serious doubt on the empirical viability of the NKPC model, even when estimated with survey inflation forecasts.     

Noisy information, interest rate shocks and the Great Moderation

In this paper we evaluate the hypothesis that the Great Moderation is partly the result of a less activist monetary policy. We simulate a New Keynesian model in which the central bank can only observe a noisy estimate of the output gap and find that the less pronounced reaction of the Federal Reserve to output gap fluctuations since 1979 can account for a substantial part of the reduction in the standard deviation of GDP associated with the Great Moderation. Our simulations are consistent with the empirically documented smaller magnitude and impact of interest rate shocks since the early 1980s.     

Announcements and credibility under inflation targeting

We inspect how inflation target announcements are instrumental in building central bank credibility and shaping inflation expectations. Investigating the role of announcements by using a time varying credibility measure, we find that both the accuracy and the frequency of inflation announcements have a positive impact on how much attention the public pays to target announcements.     

Cost-based Phillips Curve forecasts of inflation

It is a well-established idea that prices are a function of marginal cost, yet estimating a reliable measure of marginal cost is difficult to do. Stock and Watson (1999) use the Phillips Curve to forecast inflation for a variety of existing activity variables that researchers commonly use to proxy for marginal cost. This paper uses a similar type of approach to examine the performance of a new candidate for the activity variable, which is marginal cost measured following the theoretical methodology of Bils (1987), which we find to be simple yet powerful when implemented empirically. We then use the Phillips Curve to conduct pseudo out-of-sample inflation forecasts for the US using: output, unemployment, hours, the labor share, the capacity utilization rate, and the new measure of marginal cost. For almost all cases, forecast errors are lowest in the regressions with the new marginal cost variable, indicating that this new measure is an improvement over previous attempts to proxy for marginal cost.     

Geography, skills or both: What explains Fed watchers’ forecast accuracy of US monetary policy?

The paper shows that there is a substantial degree of heterogeneity in the ability of Fed watchers to forecast US monetary policy decisions. Based on a novel database for 268 individual professional forecasters since 1999, the average absolute forecast error of FOMC decisions varies 5–10 basis points between the best and worst-performers across the sample. This heterogeneity is found to be related to both the skills of analysts – such as their educational and employment backgrounds – and to geography. In particular, forecasters located in regions which experience more idiosyncratic economic conditions perform worse in anticipating monetary policy. This evidence is indicative that limited attention and heterogeneous priors are present even for anticipating important events such as monetary policy decisions.     

Implementing and interpreting indicators of core inflation: the case of France

This paper presents a comparison of alternative indicators of underlying or “core” inflation in the French case. Four broad measures are considered and implemented. The first two are inflation excluding food and energy, and the trimmed inflation indicator. We then implement two methods relying on time-series models: the Dynamic Factor Index and the structural VAR approach.  Each indicator stresses on a particular type of shock on the inflation rate, so that no simple ranking of the measures emerges. Combining the various indicators conveys valuable information for appraising short term inflation developments. As regards theoretical interpretation, no indicator is fully satisfactory, lacking an explicit representation of monetary policy. However, comparing forecast performance with respect to inflation provides some specific support in favor of trimmed mean indicators.

More effective than we thought: Central bank independence and inflation in developing countries

This study examines the effect of legal central bank independence on inflation in developing countries. In spite of the policy consensus suggesting that central bank independence is an effective tool to control inflation, the evidence is still limited, particularly for developing countries. Using a novel dataset, we analyze the effect of central bank independence on inflation for a sample of 118 developing countries between 1980 and 2013. We find that higher central bank independence is associated with lower inflation rates. This effect on inflation is stronger the more democratic a country is, but it is also present in non-democratic countries. Our results are robust to different specifications and methodologies. Furthermore, we find that all dimensions included in the measurement of central bank independence (objectives, personnel, policy, and financial independence) contribute to curb inflation. Our results shed light on which types of reforms may be more effective at fighting inflation in developing countries.     

Monetary policy and exchange rate dynamics in the Spanish economy

As the Spanish economy gets more integrated in international markets, the real exchange rate becomes a key determinant of the monetary transmission. In this paper we trace out the dynamic response of prices, output and the exchange rate following a monetary policy shock. We estimate a structural VAR model whose identification scheme is based on the long run properties common to a large class of models. The results suggest that a small model with efficient asset markets plus nominal inertia and long run monetary neutrality, captures the essential features of the monetary transmission mechanism in Spain. The interest rate shock is well identified and the exchange rate overshoots its long run value. There are no signs of liquidity puzzle nor of price puzzle or exchange rate puzzle either.     

The emerging global financial architecture and exchange rate regimes in a volatile world

Previous work has documented inflation effects on Tobin's q in the long run. This paper examines whether the FED's different policies and chairmen tenure have an impact on Tobin's q, after a modified stylized AD-AS model shows that central banks affect q. We do find changing responses of q depending on the pre-Volcker and post-Volcker periods.     

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.     

Optimal versus realized policy rules in a regime-switching framework

In this paper we compare a deterministic model and a Markov switching model to analyze the behavior of the US economy and the Federal Reserve. We examine both optimal and empirical monetary policies for the US Federal Reserve between 1960 and 2008. We compare the optimal monetary policy to the actual interest rates and to the empirical reaction function. We also evaluate the sensitivity of the results to the preferences assigned to each objective. We find that there is no unique optimal solution that fits the Federal Reserve behavior over the entire period. The best fit to the actual interest rates is obtained by an optimal policy with preference switches following the rule: a high-volatility regime coincides with a priority on inflation alone while in a low-volatility regime there is equal policy priority on output stabilization and inflation.     

Understanding the effects of technology shocks

The research led by Gali (AER 1999) and Basu et al. (AER 2006) raises two important questions regarding the validity of the RBC theory: (i) How important are technology shocks in explaining the business cycle? (ii) Do impulse responses to technology shocks found in the data reject the assumption of flexible prices? Using an RBC model, this paper argues that the conditional impulse responses of the U.S. economy to technology shocks are not grounds to reject the notion that technology shocks are the main driving force of the business cycle and the assumption of flexible prices, in contrast with the conclusions reached by the literature.     

Non-stationary inflation and panel estimates of United States short and long-run Phillips curves

This paper argues that because United States inflation has been non-stationary over the past five decades the vast body of empirical research that proceeds without adequately accounting for the non-stationarity in the data is invalid. Using 50 years of United States inflation data the standard results in the Phillips curve literature are shown to be due to unaccounted shifts in the mean rates of inflation over the period. Short and long-run Phillips curves for the United States are then estimated using time series panel data techniques that account for these shifts in mean.     

Monetary policy rules in Central and Eastern European Countries: Does the exchange rate matter?

We estimate monetary policy rules for six Central and Eastern European Countries (CEEC) during the period when they prepared for membership to the EU and monetary union. By taking changes in the policy settings explicitly into account and by splitting up the exchange rate impact into two different components we significantly improve estimation results for monetary policy rules in CEEC. We uncover that the focus of the interest rate setting behaviour in the Czech Republic, Hungary and Poland explicitly switched from defending the peg to targeting inflation. For Slovakia, however, there still seemed to be on ongoing focus on the exchange rate. Finally, Slovenia and, after a policy switch, Romania exhibit a solid relation with inflation as well.     

Modelling structural change in the UK housing market: A comparison of alternative house price models

This paper develops a new approach to the modelling of house prices in the UK, with housing demand being conditioned directly on consumers' expenditure rather than the determinants of expenditure. Conditioning on consumption ensures that the permanent income measure used in determining the level of consumption is consistently reflected in housing demand. The effects of financial liberalisation on the relative consumption of housing and non-housing goods and services are captured using the average loan-value ratio for first-time buyers. We also allow for financial effects via the real user cost of home ownership. House prices are assumed to adjust so as to clear the housing market. The proposed model is found to have structurally stable parameters across the housing market downturn since 1990. Statistical comparisons with the more conventional models in use at HM Treasury and the Bank of England during the early 1990s provide additional evidence in favour of our proposed approach.     

Assessing the effects of financial heterogeneity in a monetary union a DSGE approach

The aim of this article is to analyze how financial heterogeneity can accentuate the cyclical divergences inside a monetary union that faces technological, monetary, budgetary and financial shocks. To this purpose, this study relies on a two-country Dynamic Stochastic General Equilibrium model, where the two countries are supposed to be differently sensitive to the bank capital channel. The model allows us to demonstrate how a given symmetric shock causes cyclical divergences inside a heterogeneous monetary union. On this point, it allows reproducing some stylized facts recently observed in the Euro Area. Moreover, it appears that the more heterogeneous the union, the larger the effects of financial asymmetries on the transmission of shocks. Finally, we show that a common monetary policy contributes to worsen cyclical divergences, in comparison with monetary policies that would be nationally conducted.
