Shadow short rate and monetary policy in the Euro area

Empirical modelling of the monetary policy effects using conventional linear econometric models is put to a great test when interest rates approach the zero-lower bound. A possible remedy recently proposed in the literature is to introduce a shadow short rate (SSR) obtained from the yield curve model as an alternative monetary policy measure. This paper examines the usefulness of shadow rates as a policy stance measure for the Euro area. Moreover, the SSR can be used to study the country-specific monetary policy stance. We incorporate the shadow short rate in a standard vector autoregressive analysis to study the effects of monetary policy shocks both at the level of the Euro area and for two periphery EA countries, Italy and Spain, that endured significant financial stress during the crisis. Our analysis shows that monetary policy shocks identified form the SSR produce similar macro responses as shocks identified from the standard policy rate. The Euro area shocks can directly translate to a corresponding change in the country-specific financing conditions in the periphery, whereas the reverse effect is limited. The historical decomposition of the stochastic component of the SSR series shows that the unconventional policy measures were effective in stabilising the sovereign crisis in 2011, however, their relatively limited quantity provided only a weak stimulus to the economy.     

Unconventional monetary policy and capital flows

This paper examines the connection between the stance of domestic monetary policy and international capital flows. It first provides a simple theoretical framework describing the mechanisms behind the cross-border spillovers of domestic monetary policy. Then, it empirically investigates the impact of U.S. unconventional monetary policies (UMPs), implemented in the aftermath of the recent global financial crisis, on U.S. capital flows to developing economies and non-UMP advanced economies. The results suggest that the use of quantitative easing by the Federal Reserve has been associated with increased net portfolio flows to developing countries and, to a lesser extent, non-UMP advanced economies. An exit from these UMPs is likely to cause capital flow reversals in U.S. capital-importing countries. Countries with greater exchange rate flexibility, stronger fiscal and current account positions, and higher capital mobility are likely to fare well following an exit from UMPs in the U.S.     

A monetary vector error correction model of the Euro area and implications for monetary policy

In this paper, a vector error correction model for Euro area money, prices, output, long-term interest rate and short-term interest rate with three identified cointegration relations is specified. It is shown that Euro area money and prices can be considered as variables that are integrated of order two or I(2), that is, they have to be differenced twice to become stationary. Accordingly, the relation between money, prices and other macroeconomic variables is analyzed in an econometric framework which is suited for the analysis of I(2)-variables. Monetary policy implications are derived from the estimated system.First revision received: May 2002/Final revision received: May 2003I thank Helmut Lütkepohl, Jürgen Wolters, and two anonymous referees for helpful comments.

Unconventional monetary policy,liquidity trap,and asset prices

This article offers a fundamental critique of monetary policy implemented in the United States following the 2007–8 global financial crisis. It aims to show that the misunderstanding of the mainstream theoretical thinking underlying monetary policy actions led to the ineffectiveness of the policy response to the 2007–8 global financial crisis. The conventional view that monetary policy is the stabilization tool has serious flaws and is ineffective for bringing about economic recovery. The Federal Reserve’s experiment with the so-called unconventional monetary policy exposed the weakness of the conventional belief in understanding how banks operate, how the monetary authority can influence the yield curve, and how the monetary transmission mechanism works, resulting in prescribing an ineffective treatment to boost economic activity. In this regard, it is argued that the Federal Reserve’s decision to let long-term interest rates be market determined represents a significant self-imposed constraint, which limits policy options regarding monetary policy actions and the effective control of long-term interest rates. By limiting the setting of policy rates only to the overnight interest rate, the ability of the monetary authority to influence long-term interest rates is both weak and indirect.     

Unconventional monetary policy and household debt: The role of cash-flow effects

We study the transmission of conventional and unconventional monetary policy shocks via the loan market, distinguishing between adjustable- and fixed-rate mortgages (ARMs and FRMs, respectively) and focusing on the relative importance of the income channel. Under ARMs, a conventional monetary policy shock implies a temporary cash-flow effect leading to a redistribution between savers and borrowers, a feature that is weaker, but more persistent, under FRMs. Also, an easing via unconventional operations – modelled as a shift in households’ preferences that reduces the term premium on long-term loan rates – has an expansionary effect on output and inflation, although more muted than the one recorded via a conventional monetary policy shock. In the former case, we find a modest contribution of cash-flow effect to the dynamics of consumption.     

Unconventional monetary policy announcements and information shocks in the U.S.

We study unconventional policy shocks and information shocks associated with central bank announcements in the U.S. While unconventional policy shocks capture the direct influence of announced monetary policy actions, information shocks are associated with central bank information conveyed with the announcement. To disentangle these two types of shocks, we impose sign restrictions on high frequency changes in interest rates and stock prices around announcements. We find that information shocks lead to persistent declines in the 10-year government bond yield, whereas the actual unconventional policy shock induces only small interest rate responses. We also find that expansionary output effects of unconventional monetary policy are to some extent counteracted by the information shock.     

Shadow rates as a measure of the monetary policy stance: Some international evidence

This paper examines the usefulness of shadow rates to measure the monetary policy stance by comparing them to the official policy rates and those implied by three types of Taylor rules in both inflation-targeting countries (the UK, Canada, Australia and New Zealand) and others that have only targeted inflation at times (the United States, Japan, the Euro Area and Switzerland) over the period from the early 1990s to December 2021. Shadow rates estimated from a dynamic factor model are shown to suggest a much looser policy stance than either the official policy rates or those implied by the Taylor rules, and generally to provide a more accurate picture of the monetary policy stance during both ZLB and non-ZLB periods, since they reflect the full range of unconventional policy measures used by central banks. Furthermore, generalised impulse response analysis based on three alternative vector autoregression (VAR) models indicates that monetary shocks based on the shadow rates are more informative than those related to the official policy rates or to two- and three-factor shadow rates, especially during the Global Financial Crisis and the recent COVID-19 pandemic, when unconventional measures have been adopted. Finally, unconventional policy shocks seem to have less persistent effects on the economy in countries, which have adopted an inflation-targeting regime.     

Exchange rate movements and monetary policy in Brazil: Econometric and simulation evidence

The literature on monetary economy has aroused growing interest in macroeconomics. Due to computational advancements, models have become increasingly more complex and accurate, allowing for an in-depth analysis of the relationships between real economic variables and nominal variables. Therefore, using a dynamic stochastic general equilibrium (DSGE) model, based on Gali and Monacelli (2005), we propose and estimate a model for the Brazilian economy by employing Bayesian methods so as to assess whether the Central Bank of Brazil takes exchange rate fluctuations into account in the conduct of monetary policy. The most striking result of the present study is that the Central Bank of Brazil does not directly change the interest rate path due to exchange rate movements. A simulation exercise is also used. Our conclusion is that the economy quickly accommodates shocks induced separately on the exchange rate, on the terms of trade, interest rate, and global inflation.     

The dynamic effects of monetary policy and government spending shocks on unemployment in the peripheral Euro area countries

In this paper we study the response of unemployment to monetary policy and government spending shocks in the peripheral Euro-area countries. By applying the structural near-VAR methodology, we jointly model area-wide and national variables. Our main finding is that fiscal multipliers vary across countries and the results are consistent with the prediction of the standard New Keynesian model only in Italy and Greece. Instead, in Ireland, Portugal and Spain increases in government spending are recessionary. Thus we find that Keynesian results of fiscal policy seem to prevail in high public-debt countries, whereas non-Keynesian outcomes seem to characterize high private-debt countries. As for the monetary policy shock, we find that it plays an important role, jointly with the other area-wide shocks, as a long-term driver of national unemployment.     

Dynamics of monetary policy spillover: The role of exchange rate regimes

In a time-varying framework, our study investigates the role of exchange rate regimes in explaining monetary policy spillover across a set of AEs and EMEs. We also investigate the channels contributing to the dynamism in the degree of such spillover. We find that the flexible exchange rate regime in the AEs insulates them against the spillover to a relatively larger extent as compared to the managed float regime in the EMEs. We also find that the spillover is strongly time-varying, being influenced by macroeconomic conditions in the centre economy. Risk-taking, portfolio rebalancing, and signaling channels are found to be significant in explaining the rise in spillover in the EMEs, but not in the AEs. The rise in the connectedness of interest rates in the AEs occurred only during the global financial crisis (2008–12), owing to their higher policy coordination with the US. This should not be misconstrued as monetary policy spillover.     

Does the Euro follow the German Mark? Evidence from the monetary model of the exchange rate

This paper investigates whether German or synthetic European pre-EMU data provides the appropriate empirical basis for evaluating Euro/Dollar exchange rate behavior. Monetary exchange rate equations are estimated for both data sets over the pre-EMU period, and out-of-sample forecasts are evaluated to assess their ability to explain the Euro/Dollar exchange rate from 1999 to 2004. While forecast accuracy tests confirm the usefulness of synthetic European data for Euro exchange rate analysis, forecasts based on the German pre-EMU experience cannot even beat a random walk. Our results indicate that the Euro does not simply follow the German Mark, but that it has its origins in the other pre-EMU currencies as well.     

Some implications for monetary policy of uncertain exchange rate pass-through

The paper uses MULTIMOD to examine the implications of uncertain exchange rate pass‐through for the conduct of monetary policy. From the policymaker's perspective, uncertainty about exchange rate pass‐through implies uncertainty about policy multipliers and the impact of state variables on stabilization objectives. When faced with uncertainty about the strength of exchange rate pass‐through, policymakers will make less costly errors by overestimating the strength of pass‐through rather than underestimating it. The analysis suggests that pass‐through uncertainty of the magnitude considered does not result in efficient policy response coefficients that are smaller than those under certainty.     

Empirical analysis of the monetary policy transmission through interest rate channel in China

With the deregulation of interest rates in China, the interest rate channel of monetary policy transmission is becoming more and more important. Firstly, this paper makes empirical studies on the transmission mechanism in China represented by the conventional interest rate channel of monetary policy transmission by using the Granger causality test. The result shows that there is no causality neither between investment expenditure and the market interest rate nor between household consumption and the market interest rate, which suggests that the transmission of monetary policy in China is impeded. Then the reasons from three aspects including interest rate liberalization, asset-backed securitization and household consumption behavior are analyzed.     

The role of the exchange rate in Canadian monetary policy: evidence from a TVP-BVAR model

A time-varying parameters Bayesian structural vector autoregression (TVP-BVAR) model with stochastic volatility is employed to characterize the monetary policy stance of the Bank of Canada (BoC) in terms of an interest rate rule linking the policy rate to the output gap, inflation and the exchange rate. Using quarterly bilateral Canadian–US data, we find such an interest rate rule to have little explanatory power for the early part of our sample starting in the mid-1980s, but to become more suitable to explain interest rate dynamics from the mid-1990s onwards. Whereas the exchange rate turns out to be the major determinant of the policy rate in the 1980s, its importance declines throughout the 1990s and 2000s, although it continues to be influential even towards the end of the sample period ending in 2015Q2. We also find interest rate shocks to have become more effective in influencing the macroeconomy over time, indicating that the BoC has continually gained monetary policy credibility. We associate this development with the BoC successively de-emphasizing the role of the exchange rate in informing interest rate decisions, thereby alleviating the potential monetary policy conflict between targeting the exchange rate and maintaining the price stability goal.     

Recent monetary policy and the credit card-augmented Divisia monetary aggregates

The main objective of this paper is to examine the information content of the credit card-augmented Divisia monetary aggregates and credit card-augmented Divisia inside monetary aggregates, recently produced by the Center for Financial Stability. We compare the inference ability of the credit card-augmented Divisia monetary aggregates and credit card-augmented Divisia inside monetary aggregates to the conventional Divisia monetary aggregates, at all levels of monetary aggregation. Using cyclical correlations analysis and Granger causality tests, we find that both the conventional Divisia monetary aggregates and the credit card-augmented Divisia monetary aggregates are informative in predicting output. Moreover, during, and in the aftermath of the 2007–2009 financial crisis, the credit card-augmented Divisia measures of money are more informative when predicting real economic activity than the conventional Divisia monetary aggregates. We also find that broad Divisia monetary aggregates provide better measures of the flow of monetary services generated in the economy.     

Politics and the UK's monetary policy

This paper examines whether politics causes regime shifts in deviations from the optimal monetary policy in the United Kingdom. After using a dynamic stochastic general equilibrium model to construct the welfare-maximizing policy rule and deviations from the optimal Taylor rule, we show that politics does indeed play an important role in explaining these deviations. In addition to politics, unemployment rates account for regime shifts in the Taylor rule deviations.
