A No‐Arbitrage Structural Vector Autoregressive Model of the UK Yield Curve*

This article combines a Structural Vector Autoregression with a no‐arbitrage approach to build a multifactor Affine Term Structure Model (ATSM). The resulting No‐Arbitrage Structural Vector Autoregressive (NASVAR) model implies that expected excess returns are driven by structural macroeconomic shocks. This is in contrast with a standard ATSM, in which agents are concerned with non‐structural risks. As a simple application, we study the effects of supply, demand and monetary policy shocks on the UK yield curve. We show that all structural shocks affect the slope of the yield curve, with demand and supply shocks accounting for a large part of the time variation in bond yields.     

International spillovers of (un)conventional monetary policy: The effect of the ECB and the US Fed on non-euro EU countries

We estimate a global vector autoregression model to examine the effects of euro area and US monetary policy stances, together with the effect of euro area consumer prices, on economic activity and prices in non-euro EU countries using monthly data from 2001-2016. Along with some standard macroeconomic variables, our model contains measures of the shadow monetary policy rate to address the zero lower bound and the implementation of unconventional monetary policy by the European Central Bank and the US Federal Reserve. We find that these monetary shocks have the expected qualitative effects but their magnitude differs across countries, with southeastern EU economies being less affected than their peers in Central Europe. Euro area monetary shocks have a greater effect than those that emanate from the US. We also find certain evidence that the effects of unconventional monetary policy measures are weaker than those of conventional measures. The spillovers of euro area price shocks to non-euro EU countries are limited, suggesting that the law of one price materializes slowly.     

The Macroeconomic Effects of Shocks to Large Banks’ Capital

We propose a simple approach to quantifying the macroeconomic effects of shocks to large banks’ leverage. We first estimate a standard dynamic model of leverage targeting at the bank level and use it to derive an aggregate measure of the economic capital buffer of large US bank holding corporations. We then evaluate the response of key macro variables to a shock to this aggregate bank capital buffer using standard monetary VAR models. We find that shocks to the capital of large US banks explain a substantial share of the variance of credit to firms and real activity.     

Does Liquidity Matter? Properties of a Divisia Monetary Aggregate in the Euro Area*

This paper builds a quarterly Divisia monetary aggregate for the euro area using area‐wide data over the sample period from 1980 to 2000, finding two main results. First, it is found that the demand for this monetary aggregate has been well behaved and relatively stable over the last two decades. Secondly, the Divisia‐weighed monetary aggregate is found to have interesting information content from a forward‐looking perspective. This lends support to the view that money and – in a broader sense – liquidity services should be assigned an important role in shaping monetary policy in the euro area, although the policy maker is not interested in monetary aggregates per se.     

The macroeconomic impact of economic uncertainty and financial shocks under low and high financial stress

External financial frictions might increase the severity of economic uncertainty shocks. We analyze the impact of aggregate uncertainty and financial condition shocks using a threshold vector autoregressive (TVAR) model with stochastic volatility during distinct US financial stress regimes. We further examine the international spillover of the US financial shock. Our results show that the peak contraction in euro area industrial production due to uncertainty shocks during a financial crisis is nearly-four times larger than the peak contraction during normal times. The US financial shocks have an influential asymmetric spillover effect on the euro area. Furthermore, the estimates reveal that the European Central Bank (ECB) is more cautious in implementing a monetary policy against uncertainty shocks while adopting hawkish monetary policies against financial shocks. In contrast, the Fed adopts a more hawkish monetary policy during heightened uncertainty, whereas it acts more steadily when financial stress rises in the economy.     

The Barnett critique after three decades: A New Keynesian analysis

This paper extends a New Keynesian model to include roles for currency and deposits as competing sources of liquidity services demanded by households. It shows that, both qualitatively and quantitatively, the Barnett critique applies: while a Divisia aggregate of monetary services tracks the true monetary aggregate almost perfectly, a simple-sum measure often behaves quite differently. The model also shows that movements in both quantity and price indexes for monetary services correlate strongly with movements in output following a variety of shocks. Finally, the analysis characterizes the optimal monetary policy response to disturbances that originate in the financial sector.     

The response of asset prices to monetary policy shocks: Stronger than thought

Standard macroeconomic theory predicts rapid responses of asset prices to monetary policy shocks. Small‐scale vector autoregressions (VARs), however, often find sluggish and insignificant impact effects. Using the same high‐frequency instrument to identify monetary policy shocks, we show that a large‐scale dynamic factor model finds overall stronger and quicker asset price reactions compared to a benchmark VAR, both on euro area and US data. Our results suggest that incorporating a sufficiently large information set is crucial to estimate monetary policy effects.     

Inflation Sensitivity To Monetary Policy: What Has Changed since the Early 1980s?

Have conventional monetary policy instruments maintained the same ability to accommodate undesirable effects of shocks throughout the postwar period? Or has the changed economic environment characterizing the last 30 years diminished the sensitivity of macroeconomic volatility to systematic changes in the conduct of monetary policy? The answer is no to the first question and, consequently, yes to the second question. We estimate a medium‐scale New‐Keynesian model in two subsamples, 1955–79 and 1984–2012, and find that the sensitivity of inflation variance to changes in conventional monetary policy has declined. We document that the changed properties of the labour market largely contributed to this decline.     

Fiscal Policy in the UK

Although the conduct of macroeconomic policy in the UK has been very good by historical standards, Brian Henry argues in this article that there are shortcomings in the framework which mean it is less well suited to adverse shocks than it should be. He recommends that an extension of the present framework be made setting up a committee charged with the independent assessment of fiscal policy. This would help mitigate the lack of balance between monetary and fiscal policy which is evident at present. Fiscal judgements based on cyclical adjustments are too heavily dependant on domestic factors and underestimate the effects of the cycle on revenues. In consequence, fiscal policy, rather than supporting monetary, has been loosened and this indirectly accounts for the continuing strength of the exchange rate.     

The transmission of foreign shocks to South Eastern European economies: A Bayesian VAR approach

The paper analyses the macroeconomic effects of foreign shocks in three South-East European (SEE) economies: Croatia, Macedonia and Bulgaria. In this regard, we investigate the transmission of several eurozone shocks (output gap, money market rates and inflation) on various macroeconomic variables in the aforementioned countries (output, inflation, money market rates and budget deficits). We trace the effects of foreign shocks on the basis of impulse response functions obtained from the Bayesian Vector Auto Regressions (VARs) separately for each country. The main findings from our study are: first, economic expansion in the eurozone has strong output and inflation effects on SEE economies, implying some degree of synchronization of business cycles; second, eurozone inflation is instantly and to a great extent transmitted to domestic inflation, suggesting that inflation in the SEE economies is mostly driven by foreign inflation; third, domestic money market rates are not closely linked with eurozone money markets; fourth, monetary policy in the SEE countries does not seem to be responsive to eurozone inflation shocks; and fifth, the fiscal authorities attempt to offset the spillover effects from both economic expansion and monetary tightening in the eurozone.     

Evaluating New‐Keynesian Models of a Small Open Economy*

We suggest a strategy to evaluate members of a class of New‐Keynesian models of a small open economy. As an example, we estimate a modified version of the model in Svensson [Journal of International Economics (2000) Vol. 50, pp. 155–183] and compare its impulse response and variance decomposition functions with those a structural vector autoregression (VAR) model. The focus is on responses to foreign rather than to domestic shocks, which facilitates identification. Some results are that US shocks account for large shares of the variance of Canadian variables, that little of this influence is due to real exchange rate movements, and that Canadian monetary policy is not adequately described by a Taylor rule.     

The time-varying correlation between output and prices in the United States over the period 1800–2014

In this study, we examine the time-varying correlations between output and prices, while controlling for the impact of the monetary policy stance and output and inflation uncertainties over the period 1800–2014. The results of the empirical analysis reveal that the dynamic correlations of output and prices were typically negative, suggesting a countercyclical behaviour of prices, apart from the early 1840s and from the beginning until the middle of the 20th century, when the correlation was positive, indicating a procyclicality of prices. A historical decomposition analysis based on a sign-restricted structural vector autoregressive model is able to relate the procyclical and countercyclical behaviour to the predominance of aggregate supply and aggregate demand and/or monetary policy shocks, respectively. Moreover, inflation uncertainty (monetary policy stance) was found to have a positive (negative) effect on inflation over the last 215 years.     

On the feasibility of monetary union among Gulf Cooperation Council (GCC) countries: does the symmetry of shocks extend to the non-oil sector?

GCC countries’ output is heavily dichotomized into oil and non-oil. Oil shocks have similar effects on all member countries but little is known about their responses to non-oil shocks. This paper sets out to determine (1) whether aggregate demand (AD) and non-oil supply shocks (AS) are symmetrical across these countries to justify their suitability for monetary union; and (2) whether there is any commonality of shocks with the United States and the three major European countries, namely France, Germany, and Italy, which can warrant the choice of either the US dollar or the Euro as the anchor for the expected common currency of the bloc. We use bivariate structural vector autoregression models identified with long-run restrictions to extract the shocks. Our results show that (a) AD shocks are unequivocally symmetrical but non-oil AS shocks are weakly symmetrical across GCC countries thereby suggesting a monetary union is feasible, but not overwhelmingly; (b) neither AD nor AS shocks are symmetrical between GCC countries and the selected European countries; (c) GCC’s AD shocks are symmetrical with the US but non-oil AS shock are not. Furthermore, there are no significant changes in the results when we aggregate the GCC countries as a bloc. We therefore surmise that the US dollar is a more appropriate anchor for the new currency than the Euro since US monetary policy can at least help smooth demand shocks in GCC countries.     

What does a Monetary Policy Shock Do? An International Analysis with Multiple Filters*

What does a monetary policy shock do? We answer this question by estimating a new‐Keynesian monetary policy dynamic stochastic general equilibrium model for a number of economies with a variety of empirical proxies of the business cycle. The effects of two different policy shocks, an unexpected interest rate hike conditional on a constant inflation target and an unpredicted drift in the inflation target, are scrutinized. Filter‐specific Bayesian impulse responses are contrasted with those obtained by combining multiple business cycle indicators. Our results document the substantial uncertainty surrounding the estimated effects of these two policy shocks across a number of countries.     

Macroeconomic responses of emerging market economies to oil price shocks: An analysis by region and resource profile

We analyze the impact of oil price shocks on the macroeconomic fundamentals in emerging economies in three regions that have different resource endowments. The existing literature on emerging economies remains inconclusive on how regional factors and resource characteristics affect the response of macroeconomic variables to oil price shocks. We show that (1) exports in Europe and Central Asia are driven by oil more than East Asia and the Pacific and that (2) policy makers in East Asia and the Pacific should be concerned about real exchange appreciation following a positive oil shock to mitigate losses in the non-oil export market. Analysis by resource endowment further reveals that, in less-resource-intensive economies, an oil price shock causes large variations in consumption and has a negative and persistent impact on the real gross domestic product (GDP). In mineral-exporting economies, real GDP and interest rates are driven largely by oil price shocks. The response of real GDP in mineral-exporting economies is short lived. In oil-exporting economies, only real GDP has a large variation in response to oil price shocks. Our findings highlight the need for customized policy responses to oil price shocks, depending on resource endowments, as we show that a “one size fits all" policy does not exist.     

Macroeconomic news and the returns of financial companies

This research is concerned with the response of the NASDAQ Financial 100 index to macroeconomic news. The paper employs the newly developed technique of generalized impulse response analysis to examine how macroeconomic shocks affect the performance of the financial sector. The results identify the magnitude and persistence of the response of financial companies stock returns arising from shocks to the stance of monetary policy, real output, inflation, and risk. The findings add to the literature on the determinants of financial sector stocks and on the relationship between the stock market and the macroeconomy. Copyright © 2002 John Wiley & Sons, Ltd.     

Combining Time Variation and Mixed Frequencies: an Analysis of Government Spending Multipliers in Italy

In this paper, we propose a time‐varying parameter vector autoregression (VAR) model with stochastic volatility which allows for estimation on data sampled at different frequencies. Our contribution is twofold. First, we extend the methodology developed by Cogley and Sargent (Drifts and volatilities: monetary policies and outcomes in the post WWII U.S. Review of Economic Studies 2005; 8 : 262–302) and Primiceri (Time varying structural vector autoregressions and monetary policy. Review of Economic Studies 2005; 72 : 821–852) to a mixed‐frequency setting. In particular, our approach allows for the inclusion of two different categories of variables (high‐frequency and low‐frequency) into the same time‐varying model. Second, we use this model to study the macroeconomic effects of government spending shocks in Italy over the 1988:Q4–2013:Q3 period. Italy—as well as most other euro area economies—is characterized by short quarterly time series for fiscal variables, whereas annual data are generally available for a longer sample before 1999. Our results show that the proposed time‐varying mixed‐frequency model improves on the performance of a simple linear interpolation model in generating the true path of the missing observations. Second, our empirical analysis suggests that government spending shocks tend to have positive effects on output in Italy. The fiscal multiplier, which is maximized at the 1‐year horizon, follows a U‐shape over the sample considered: it peaks at around 1.5 at the beginning of the sample; it then stabilizes between 0.8 and 0.9 from the mid 1990s to the late 2000s, before rising again to above unity during the recent crisis.

CENTRAL BANK POLICIES AND INCOME AND WEALTH INEQUALITY: A SURVEY

This paper reviews recent research on the relationship between central bank policies and inequality. A new paradigm which integrates sticky‐prices, incomplete markets, and heterogeneity among households is emerging, which allows for the joint study of how inequality shapes macroeconomic aggregates and how macroeconomic shocks and policies affect inequality. The new paradigm features multiple distributional channels of monetary policy. Most empirical studies, however, analyze each potential channel of redistribution in isolation. Our review suggests that empirical research on the effects of conventional monetary policy on income and wealth inequality yields mixed findings, although there seems to be a consensus that higher inflation, at least above some threshold, increases inequality. In contrast to common wisdom, conclusions concerning the impact of unconventional monetary policies on inequality are also not clear cut. To better understand policy effects on inequality, future research should focus on the estimation of General Equilibrium models with heterogeneous agents.     

Monetary policy shocks: We got news!

We assess the role of monetary policy news shocks in the context of a medium scale DSGE model estimated on US data. We estimate several versions of the model and find decisive evidence in favour of the inclusion of monetary policy news shocks over a two-quarter horizon. According to our results, monetary policy news shocks account for a non-negligible fraction of the variance of real variables, especially at shorter forecast horizons. Further, we document that the importance of monetary policy news shocks goes beyond what was observed in recent years. The historical importance of monetary policy news shocks dates back to the 1999–2006 period when the official FOMC statements provided information about both the current policy setting and the expected future policy path. We also show that adding monetary policy news shocks to the model does not lead to identification problems.
