Bank herding and systemic risk

Bank herding behavior is often hypothesized to increase systemic risk, but the actual effect is unclear ex-ante from the theory and unknown ex-post from the data. We expand the literature on this topic in several dimensions – posing alternative hypotheses regarding the effects of herding in asset, liability, and off-balance sheet portfolios; developing a novel set of bank-specific, time-varying measures of herding in these portfolios; and empirically testing the relations between bank herding for all three portfolios and bank systemic risk contributions. We find nuanced empirical results that differ by portfolio, bank size class, and periods before versus after TARP.     

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.     

Monetary Policy; Questions of Adequacy, Design and Presentation

In this article John Flemming considers three possible modifications to the presentation and design of monetary policy. He argues first that it is odd to forecast the target variable – inflation – when it is policy to do what is necessary to deliver the target. What would be interesting would be a forecast of what interest rates might prove necessary. Secondly he considers the possibility that with monetary policy dedicated to price stability and fiscal policy to paying for public expenditure – and stabilising output – a third control might be appropriate to stabilise the financial system. Finally, and overlapping with the last, he explores ways in which asset price changes might be reflected in a broader measure of inflation – as recently suggested by Charles Goodhart and the IMF.     

Monetary policy,housing rents,and inflation dynamics

In this paper we study the effect of monetary policy shocks on housing rents. Our main finding is that, in contrast to house prices, housing rents increase in response to contractionary monetary policy shocks. We also find that, after a contractionary monetary policy shock, rental vacancies and the homeownership rate decline. This combination of results suggests that monetary policy may affect housing tenure decisions (own versus rent). In addition, we show that, with the exception of the shelter component, all other main components of the consumer price index (CPI) either decline in response to a contractionary monetary policy shock or are not responsive. These findings motivated us to study the statistical properties of alternative measures of inflation that exclude the shelter component. We find that measures of inflation that exclude shelter have most of the statistical properties of the widely used measures of inflation, such as the CPI and the price index for personal consumption expenditures, but have higher standard deviations and react more to monetary policy shocks. Finally, we show that the response of housing rents accounts for a large proportion of the “price puzzle” found in the literature.     

Content horizons for univariate time-series forecasts

This paper investigates the maximum horizon at which conditioning information can be shown to have value for univariate time series forecasts. In particular, we consider the problem of determining the horizon beyond which forecasts from univariate time series models of stationary processes add nothing to the forecast implicit in the unconditional mean. We refer to this as the content horizon for forecasts, and provide a formal definition of the corresponding forecast content function at horizons s=1,… S. This function depends upon parameter estimation uncertainty as well as on autocorrelation structure of the process. We show that for autoregressive processes it is possible to give an asymptotic expression for the forecast content function, and show by simulation that the expression gives a good approximation even at modest sample sizes. The results are applied to the growth rate of GDP and to inflation, using US and Canadian data.     

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.     

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.     

Interest rate movements and US consumers’ inflation forecast errors: is there a link?

The Fisher effect maintains that movements in short-term interest rates largely reflect changes in expected inflation. Since expected inflation is subject to error, we ask whether interest rates move in response to over- and under-predictions of inflation. In answering, we measure expected inflation by the consumers’ forecast of inflation derived from the Michigan Surveys of Consumers (MSC). Our findings for 1978–2013 indicate that the MSC inflation forecasts were unbiased, efficient, and directionally accurate. For 1978–2007, (i) interest rates moved downward (upward) in response to MSC over-predictions (under-predictions) of inflation, and (ii) MSC inflation forecast errors had directional predictability for interest rates. However, no link between interest rate movements and MSC inflation forecast errors is detected for 2008–2013 when monetary policy kept short-term interest rates unusually low.     

Optimal monetary policy under incomplete markets and aggregate uncertainty: A long-run perspective

This paper examines the role of monetary policy in an environment with aggregate risk and incomplete markets. In a two-period overlapping-generations model with aggregate uncertainty, optimal monetary policy attains the ex-ante Pareto optimal allocation. This policy aims to stabilize the savings rate in the economy by changing real returns of nominal bonds via variation in expected inflation. Optimal expected inflation is procylical and on average higher than without uncertainty. Simple inflation targeting rules closely approximate the optimal monetary policy.     

THE 1987 BUDGET

Our pre-Budget forecast published last month correctly anticipated the main Budget measures (with the exception of the decision not to re-valorise excise duties) and is very close to the Treasury's own forecast. We have updated the forecast for the Budget measures and other new information. Compared with the February Economic Outlook, our post-Budget assessment has revised down slightly the short-term forecast for output, inflation and the current account deficit. Consequently we share the Treasury's view that output will rise 3 per cent this year, but we are a little more optimistic on the outlook for inflation and the current account.
In holding the PS BR to last year's expected outturn of £4bn, and more particularly in cutting the PSFD by £11/2zbn, the Budget represents a tightening in fiscal policy. Whether the overall policy stance is tightened depends on the response of the monetary authorities. Early indications are that the government will prevent interest rates from falling as far or as fast as they would otherwise do and that the exchange rate will be allowed to rise. This implies a tightening of policy in order to head off problems on inflation or the balance of payments. This argument is supported by the Treasury's own forecast, which is more pessimistic on both inflation and the current account than its predecessor in the Autumn Statement, and explains the Chancellor's decision not to re-valorise excise duties. The post-Budget forecast incorporates this change in policy. We now assume that the sterling index averages 70 this year and that base rates fall to 9 per cent by the end of the year.     

Does trade integration alter monetary policy transmission?

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts domestic inflation: a monetary contraction which appreciates the exchange rate lowers the local currency price of imported goods; this, in turn, induces domestic producers to lower their prices too. We pin down key parameters of the model by matching impulse responses obtained from a vector autoregression on time series for the US relative to the euro area. Our estimation procedure yields plausible parameter values and suggests a strong role for strategic complementarities. Counterfactual simulations show that openness alters monetary transmission significantly. While the contractionary effect of a monetary policy shock on inflation and output tends to increase in openness, we find that monetary policy's control over inflation increases, as the output decline which is necessary to bring about a given reduction of inflation is smaller in more open economies.     

Evaluating monetary policy under preferences with zero wealth effect: A Bayesian approach

Both real and monetary macro models have parallely exploited the potential for various preferences in accounting for empirical facts. This paper brings the two literatures together by estimating time non-separable preferences with habit formation in consumption that nests several commonly used preferences. In the absence of wealth effects and external habits, these preferences fail to generate observed inflation inertia and output persistence after a monetary policy shock. Furthermore, the data strongly rejects these preferences in favor of preferences with external habits. An alternative solution is to include habit adjusted intermediate wealth effect preferences which are able to simultaneously generate sluggish responses of the variables to a monetary policy shock and fit the data better.     

POST-BUDGET ASSESSMENT AND ANALYSIS OF OIL PRICE CHANGES

In this Forecast Release we update our February forecast to take account of the Budget and other new information, particularly about oil prices and the exchange rate. This updated forecast is then used as the basis for a set of three simulations in which we explore the consequences of lower oil prices, a fall in the exchange rate and a tightening of fical and monetary policy. The main conclusions are first that the Budget (the contentr of which we broadly anticipated) has not significantly changed our assessment of the short-term prospects for output and inflation. However, a detailed examination of the Government's revenue and expenditure estimates suggests that fiscal policy in 1983-4, though broadly in line with the Medium-Term Financial Strategy, has been loosened compared with 1982-3 by rather more than appears from the PSBR projections. We ako believe that there is a risk that the PSBR will be significantly higher than officially forecast in 1983-4.
Our simulations show the size of the PSBR overshoot in the event of a further sharp fall in the oil price. I f this were accompanied by a fall in the exchange rate, inflation would quickly be back in double figures. Whether the exchange rate falls or not a lower oil price gives significant output gains. However, if the authorities reacted by tightening fiscal and monetary policy, inflation would be broadly the same as in the Post Budget forecast, but there would still be output gains from the lower oil price.     

Why big fiscal deficits and low inflation can coexist

• ▀ The surge in government debt caused by ballooning fiscal deficits is a necessary response to the coronavirus crisis. But we doubt this will lead to a burst of inflation in the advanced economies (AEs), let alone a debt crisis.
• ▀ Our fiscal forecasts assume AEs’ budget deficits averaged 20% of GDP or so in Q2. However, our deficit forecasts point to a sharp narrowing thereafter and for public debt as a share of GDP to peak in 2021.
• ▀ The risks around this forecast skew firmly towards deficits remaining wide, reflecting the balance of risks around our GDP forecasts and the possibility that governments allow some fiscal slippage.
• ▀ A slower narrowing of fiscal deficits than we forecast wouldn't automatically lead to a period of above-target inflation. Indeed, we wouldn't be surprised if larger-than-expected deficits were associated with weak inflation.
• ▀ High levels of corporate debt and weak labour markets raise the risk of private sector retrenchment ahead. In that case, large and sustained fiscal deficits may be needed to fill the vacuum and prevent GDP and inflation from falling. As has been the case in Japan over the past 25 years, large deficits over coming years could be associated with weak GDP growth and below-target inflation.
• ▀ If economies begin to overheat but governments keep fiscal policy loose, inflation could, of course, pick up. But central bank tightening would offset it. We believe the risk of sustained inflation overshoots is limited unless monetary policy were made subservient to governments’ own objectives. And we think the risk of central banks losing independence remains slim.

     

Asset market response to monetary policy news from SNB press releases

This paper analyses the effects of Swiss National Bank (SNB) communication on asset prices. It distinguishes between different monetary policy news contained in press releases following a monetary policy decision. Employing a latent variable approach and event-study methods, I find that medium- and long-term bond yields respond to changes in the communicated inflation and GDP forecasts as well as to the degree of pessimism expressed in press releases. Exchange rates mainly react to changes in the GDP forecast while stocks do not react to SNB communication on monetary policy announcement days. Additionally, short-term expectations about the future path of the policy rate are driven by the communicated inflation forecast. The results underline the role of qualitative news beyond quantitative forecasts in influencing market expectations and asset prices.     

中国核心通货膨胀的估计

准确地测度通货膨胀是认识一般价格水平的变化状况和制定反通货膨胀政策措施的基础。然而，现在被广泛用来测度通货膨胀的RPI或CPI及其对它的改进与通货膨胀的经济内容不一致。这就使得在这些方法下测度的通货膨胀不可能准确地反映实际通货膨胀的状况。于是，本文依据货币数量论提出了一种利用长期识别限制的结构性向量自回归模型来测度核心通货膨胀的新方法。在这个方法里，核心通货膨胀被定义为货币冲击引起的一般价格水平的变化。从向量自回归模型中识别出来的货币冲击和一般价格水平对货币冲击的反应函数被用来构造RPI或CPI变化率由货币冲击引起的成分，这样测度的核心通货膨胀与货币主义理论下通货膨胀的经济内容完全一致。用这种方法估计1954-2002年间中国核心通货膨胀过程中所提供的经济证据表明，我们对核心通货膨胀的定义和估计方法看起来非常合理。而且，测度的结果还能够帮助我们认识我国历史上每一次通货膨胀和通货紧缩的形成机制。     

Inflation tax in the lab: a theoretical and experimental study of competitive search equilibrium with inflation

In this paper we measure the effect of the inflation tax on economic activity and welfare within a controlled setting. To do so, we develop a model of price posting and monetary exchange with inflation and finite populations. The model, which provides a game–theoretic foundation to Rocheteau and Wright (2005)׳s competitive search monetary equilibrium, is used to derive theoretical propositions regarding the effects of inflation in this environment, which we test with a laboratory experiment that closely implements the theoretical framework. We find that the inflation tax is harmful – with cash holdings, production and welfare all falling as inflation rises – and that its effect is relatively larger at low inflation rates than at higher rates. For instance, for inflation rates between 0% and 5%, welfare in the two markets we consider (2[seller]×2[buyer] and 3×2) falls by roughly 1 percent for each percentage–point rise in inflation, compared with 0.4 percent over the range from 5% to 30%. Our findings lead us to conclude that the impact of the inflation tax should not be underestimated, even under low inflation.     

Impact of uncertainty on high frequency response of the U.S. stock markets to the Fed's policy surprises

This paper examines the impact of uncertainty on estimated response of stock returns to U.S. monetary policy surprise. This is motivated by the Lucas island model which suggests an inverse relationship between the effectiveness of a policy and the level of uncertainty in the economy. Using high frequency daily data from the Federal funds futures market, we first estimate the response of S&P 500 stock returns to monetary policy surprises within the time varying parameter (TVP) model. We then analyze the relationship of these time varying estimates with the benchmark VIX index and alternative measures of uncertainty. Evidence suggests a significant negative relationship between the level of uncertainty and the time varying response of S&P 500 stock returns to unanticipated changes in the interest rate. Thus, at higher levels of uncertainty the impact of monetary policy shocks on stock markets is lower. The results are robust to different measures of uncertainty.     

Testing the Structural Interpretation of the Price Puzzle with a Cost‐Channel Model*

We estimate a variety of small‐scale new‐Keynesian DSGE models with the cost channel to assess their ability to replicate the ‘price puzzle’, i.e. the inflationary impact of a monetary policy shock typically arising in vector autoregression (VAR) analysis. To correctly identify the monetary policy shock, we distinguish between a standard policy rate shifter and a shock to ‘trend inflation’, i.e. the time‐varying inflation target set by the Fed. Our estimated models predict a negative inflation reaction to a monetary policy tightening. We offer a discussion of the possible sources of mismatch between the VAR evidence and our own.     

Evolving United States stock market volatility: The role of conventional and unconventional monetary policies

Despite the econometric advances of the last 30 years, the effects of monetary policy stance during the boom and busts of the stock market are not clearly defined. In this paper, we use a structural heterogeneous vector autoregressive (SHVAR) model with identified structural breaks to analyse the impact of both conventional and unconventional monetary policies on U.S. stock market volatility. We find that contractionary monetary policy enhances stock market volatility, but the importance of monetary policy shocks in explaining volatility evolves across different regimes and is relative to supply shocks (and shocks to volatility itself). In comparison to business cycle fluctuations, monetary policy shocks explain a greater fraction of the variance of stock market volatility at shorter horizons, as in medium to longer horizons. Our basic findings of a positive impact of monetary policy on equity market volatility (being relatively stronger during calmer stock market periods) are also corroborated by analyses conducted at the daily frequency based on an augmented heterogeneous autoregressive model of realised volatility (HAR-RV) and a multivariate k-th order nonparametric causality-in-quantiles framework. Our results have important implications both for investors and policymakers.
