Do central banks respond to exchange rate movements? A structural investigation

We estimate a small-scale, structural general equilibrium model of a small open economy using Bayesian methods. Our main focus is the conduct of monetary policy in Australia, Canada, New Zealand and the UK. We consider generic Taylor-type rules, where the monetary authority reacts in response to output, inflation, and exchange-rate movements. We perform posterior odds tests to investigate the hypothesis whether central banks do target exchange rates. The main result of this paper is that the central banks of Australia and New Zealand do not, whereas the Bank of Canada and the Bank of England do include the nominal exchange rate in its policy rule. This result is robust for various specification of the policy rule. We also find that terms-of-trade movements do not contribute significantly to domestic business cycles.     

The impact of monetary policy on the exchange rate: evidence from three small open economies

This paper studies the impact effect of monetary policy shocks on the exchange rate in Australia, Canada, and New Zealand during the 1990s. Shocks are identified by the reaction of three month market interest rates to policy announcements that were not themselves endogenous to economic news on the same day. The main result is that a 100 basis point contractionary shock will appreciate the exchange rate by 2-3 percent on impact. The association of interest rate hikes with depreciations that is sometimes observed during periods of exchange market pressure is mainly attributable to reverse causality.     

Effects of Monetary Policy Shocks on Farm Prices and Exchange Rates in Korea

The effects of monetary policy shocks on farm prices and exchange rates in Korea are empirically investigated by using vector auto-regression models with sign restrictions on impulse responses. The main empirical results are as follows. First, (contractionary) monetary policy shocks have significantly negative effects on real farm prices. Second, the SR effect on farm prices is significant but short-lived. The dynamic response of farm prices is consistent with the predictions of the “overshooting” model. Third, the effects of monetary policy shocks on farm prices are more significant than the effects of monetary policy shocks on exchange rates.     

External shocks, U.S. monetary policy and macroeconomic fluctuations in emerging markets

Estimated structural VARs show that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect interest rates and the exchange rate in a typical emerging market quickly and strongly. The price level and real output in a typical emerging market respond to U.S. monetary policy shocks by more than the price level and real output in the U.S. itself. These findings are consistent with the idea that “when the U.S. sneezes, emerging markets catch a cold.” At the same time, U.S. monetary policy shocks are not important for emerging markets relative to other kinds of external shocks.     

Monetary policy,exchange rates and stock prices in the Middle East region

A structural vector autoregressive model is employed to investigate the impact of monetary policy and real exchange rate shocks on the stock market performance of Kuwait, Oman, Saudi Arabia, Egypt and Jordan. In order to identify the structural shocks both short run and long run restrictions are applied. Unlike previous literature the contemporaneous interdependence between the financial variables is left unrestricted to give a more accurate depiction of the relationships. The heterogeneity of the results reflects the different monetary policy frameworks and stock market characteristics of these countries. Mainly, monetary policy and the real exchange rate shocks have a significant short run impact on the stock prices of the countries that apply a relatively more independent monetary policy and flexible exchange rates.     

Corporate debt and unconventional monetary policy: The risk-taking channel with bond and loan contracts

We investigate the effects of unconventional monetary policies on corporate debt through the risk-taking channel using corporate bond and syndicated loan contracts from 2000 to 2016 in Japan. In this period, the policy rate remained fixed near the zero bound. Using the daily changes in the yield curve on monetary policy meeting days, we identify one call rate shock and two unconventional monetary policy shocks that do not affect short-term rates. We find that QE shocks, which move all medium-to-long-term rates, increase the maturity of debt contracts, especially for syndicated loans. In addition, such QE shocks decrease the size of corporate bonds with short maturity. On the other hand, QQE shocks, which raise medium-term rates and lower long-term rates, decrease the size of loans and corporate bonds with longer maturity. These effects imply the existence of the risk-taking channel of unconventional monetary policy: it stimulates investment in longer-maturity assets and decreases investment in assets with lower yields. Our findings show that unconventional policies affect debt contracts even in an extremely low interest rate environment.     

Capital controls and optimal Chinese monetary policy

China׳s external policies, including capital controls, managed exchange rates, and sterilized interventions, constrain its monetary policy options for maintaining macroeconomic stability following external shocks. We study optimal monetary policy in a dynamic stochastic general equilibrium (DSGE) model that incorporates these “Chinese characteristics”. The model highlights a monetary policy tradeoff between domestic price stability and costly sterilization. The same DSGE framework allows us to evaluate the welfare implications of alternative liberalization policies. Capital account and exchange rate liberalization would have allowed the Chinese central bank to better stabilize the external shocks experienced during the global financial crisis.     

Monetary policy transparency and pass-through of retail interest rates

This paper examines the degree of pass-through and adjustment speed of retail interest rates in response to changes in benchmark market rates in New Zealand during the period 1994–2004. We consider the effects of policy transparency and financial structure of the monetary transmission mechanism. New Zealand is the first OECD country to adopt a full-fledged inflation targeting regime with specific accountability and transparency provisions. Policy transparency was further enhanced by a shift from quantity (settlement cash) to price (interest rate) operating targets in 1999. Using Phillips–Loretan estimates of cointegrating regressions we find complete long-term pass-through for some but not all retail rates. Our results also show that the introduction of the Official Cash Rate (OCR) increased the pass-through of floating and deposit rates but not fixed mortgage rates. In line with previous studies we find the immediate pass-through of market interest rates to bank retail rates to be incomplete. Although we find no statistical evidence for asymmetric response of retail rates to changes in market rates other than for business lending rates in the pre OCR period, differences in the magnitude of mean adjustment lags indicate that banks appear to pass on decreases to fixed mortgage rates faster. Overall, our results confirm that monetary policy rate has more influence on short-term interest rates and that increased transparency has lowered instrument volatility and enhanced the efficacy of policy.     

Reconsidering the role of money for output, prices and interest rates

New Keynesian models of monetary policy downplay the role of monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. This paper evaluates the empirical validity of this prediction by studying the effects of shocks to monetary aggregates using a vector autoregression (VAR). Shocks to monetary aggregates are identified by the restrictions suggested by New Keynesian monetary models. Contrary to the theoretical predictions, shocks to broad monetary aggregates have substantial and persistent effects on output, prices and interest rates.     

The information content of the exchange rate and the stability of real output under alternative exchange-rate regimes

When the exchange rate is flexible, and thus responds to market forces, it provides agents with useful information, while when it is fixed (by a feedback rule) it does not. The implications of this asymmetry for the stability of real output under the two regimes is discussed. It is shown that whenever shocks are predominantly of one variety, or when domestic monetary shocks accompanied by one real shock, a flexible exchange rate does a better job of stabilizing real output than does a fixed exchange rate. These results undermine arguments favoring fixed exchange rates because they ‘discipline’ monetary policy. In addition, it is demonstrated that managed floating rules and exchange rate feedback rules are irrelevant for the distribution of real output.     

Federal reserve's policy,global equity markets,and the local monetary policy stance

This paper examines the extent to which local monetary policy stance determines the strength of US monetary policy international transmission to global equities. Using a sample of 35 countries, we document that US monetary policy surprises exert significant inverse effects on global equity returns. Our results suggest that countries whose policy rates are brought into line with that of the US are less sensitive to US monetary policy shocks only when they have a high and intermediate level of cross-border financial linkages, and only when they have a low and intermediate level of exchange rate volatility.     

Efficiency and a simple model of exchange-rate determination

A monetary model has no intrinsic dynamics so the intertemporal behavior of exchange rates, spot and forward, depend entirely upon the time processes of the exogenous variables. For typical values of interest elasticities of money demand, only if all shocks are permanent do exchange rates follow random walks.Recently, changes in relative outputs and money supplies in the Canadian–US context have evidenced serial correlation so that shocks are not exclusively permanent ones. None the less, exchange rates have followed a random walk. This suggests that the monetary model is an inappropriate specification and that models which pay attention to the choice of currency of denomination deserve greater attention.     

Real exchange rate persistence and monetary policy rules

The objective of this paper is to analyze the effects of alternative monetary rules on real exchange rate persistence. Using a two-country stochastic dynamic general equilibrium with nominal price stickiness and local currency pricing, we will show how the persistence of purchasing power parity deviations can be related to a monetary theory of these deviations. When monetary policy lean against the wind, there is no relationship of proportionality between the time during which prices remain sticky and the persistence of the response of the real exchange rate: in this case high nominal price rigidity is not sufficient, per se, in generating any persistence following a monetary shock. Moreover, we emphasize the role of interest rates smoothing policies and relative price stickiness within countries in understanding the relationship between the real exchange rate and monetary shocks. With reasonable parameters values, a wide range of monetary policy rules can generate real exchange rate autocorrelations around the ones observed in the data.     

Identifying sources of macroeconomic and exchange rate fluctuations in the UK

Using quarterly data for the period 1985:1–2011:1, this paper uses a stylised, open economy, structural VAR model to identify the types of shocks responsible for macroeconomic fluctuations in the UK economy. The stylised model implies a set of short-run restrictions that allow for the identification of the shocks. The importance of each shock is determined by examining forecast-error variance decompositions, impulse response functions, and implied long-run (or permanent) effects. The results presented here imply that two shocks (called the technology and IS shocks) are relatively more important than other shocks. Monetary shocks do exhibit long-run monetary neutrality, but clearly monetary policy is not responsible for a meaningful share of output and employment fluctuations during the sample period. The estimated VAR and structural disturbances imply that the model accurately reflects the UK economy. There is little evidence of a price puzzle or an exchange rate puzzle (evidence against uncovered interest rate parity) in response to an unexpected monetary policy tightening.     

Real exchange rate dynamics revisited: A case with financial market imperfections

In this paper, we investigate the relationship between real exchange rate dynamics and financial market imperfections. For this purpose, we first construct a New Open Economy Macroeconomics (NOEM) model that incorporates staggered loan contracts as a simple form of the financial market imperfections. Our model with such a financial market friction replicates persistent, volatile, and realistic hump-shaped responses of real exchange rates, which have been thought very difficult to materialize in standard NOEM models. Remarkably, these realistic responses can materialize even with both supply and demand shocks, such as cost-push, loan rate, and monetary policy shocks. This implies that the financial market development is a key element for understanding real exchange rate dynamics.     

Monetary policy shocks: : Testing identification conditions under time-varying conditional volatility

We propose an empirical procedure, which exploits the conditional heteroscedasticity of fundamental disturbances, to test the targeting and orthogonality restrictions imposed in the recent VAR literature to identify monetary policy shocks. Based on U.S. monthly data for the post-1982 period, we reject the non-borrowed-reserve and interest-rate targeting procedures. In contrast, we present evidence supporting targeting procedures implying more than one policy variable. We also always reject the orthogonality conditions between policy shocks and macroeconomic variables. We show that using invalid restrictions often produces misleading policy measures and dynamic responses. These results have important implications for the measurement of policy shocks and their temporal effects as well as for the estimation of the monetary authority's reaction function.     

The Effects of Productivity Shocks,Financial Shocks,and Monetary Policy on Exchange Rates: An Application of the Currency Crisis Model and Implications for Emerging Market Crises

What kind of shock affects exchange rate dynamics? How much of an effect does the monetary policy have on exchange rates? To answer these questions empirically based on the currency crisis model, I use panel data on 51 emerging countries from 1980 to 2011, identify shocks, and apply instrumental variable methods. I found that both productivity shocks and shocks to a country’s risk premium affect exchange rates and a 1 percentage point increase in the policy interest rate is associated with a 1 percentage point appreciation of domestic currency. I further apply this method to Asian and Latin-American crises.     

Monetary versus fiscal policy in India: an SVAR analysis

Conventionally, the policymakers relied on three policy alternatives to manage business cycles – debt-financed government spending, debt-financed tax rebate and interest rate. While the first two are fiscal policy instruments, the latter is a monetary policy instrument. This paper aims to capture interactions among Indian monetary and fiscal policy actions, and the impact of such policy actions on select macroeconomic variables for the period 1990Q1–2011Q4. The policy actions are identified using the sign restrictions approach combined with magnitude restrictions in a Structural Vector Autoregression framework, and interpreted using impulse responses and variance decomposition. The results show that Indian monetary policy responds to tax rebate shocks and spending shocks differently. In the case of a tax rebate shock, Indian monetary policy responds by reducing interest rates thereby accommodating fiscal expansion. On the opposite, monetary policy seems not to accommodate expenditure shocks. Interestingly, the monetary policy shock is accompanied by a fiscal expansion that threatens the credibility of the central bank actions, thus indicating fiscal policy dominance. A comparison of the efficacy of the policies suggests that the interest rate is more effective in stimulating output. Out of the two fiscal policy instruments analysed, the tax rebate seems to be the better option for stimulating output considering the output-debt trade-off.     

Identifying Monetary Policy Shocks via Changes in Volatility

A central issue of monetary policy analysis is the specification of monetary policy shocks. In a structural vector autoregressive setting there has been some controversy about which restrictions to use for identifying the shocks because standard theories do not provide enough information to fully identify monetary policy shocks. In fact, to compare different theories it would even be desirable to have over-identifying restrictions that would make statistical tests of different theories possible. It is pointed out that some progress toward over-identifying monetary policy shocks can be made by using specific data properties. In particular, it is shown that changes in the volatility of the shocks can be used for identification. Based on monthly U.S. data from 1965 to 1996 different theories are tested and it is found that associating monetary policy shocks with shocks to nonborrowed reserves leads to a particularly strong rejection of the model whereas assuming that the Fed accommodates demand shocks to total reserves cannot be rejected.     

耐用品、投资专有冲击与货币政策福利

本文构建蕴含耐用品与非耐用品的两部门DSGE模型,研究投资专有冲击对货币政策及社会福利的影响。投资专有技术进步改进了投资转化为生产资本的效率,放大边际成本波动,增加了厂商调价动机和价格水平变动。即使耐用品价格完全灵活,最优货币政策也无法同时稳定价格和实际GDP。研究发现:(1)耐用品相对价格缺口波动率的上升虽然增加了实际GDP波动,但能够有效地降低投资专有技术对边际成本的冲击,减少价格变动的福利损失。所以两部门投资专有冲击时,央行倾向于稳定价格水平。与其相反,在单部门投资专有冲击和两部门生产技术冲击时,最优货币政策应降低耐用品相对价格缺口波动,稳定实际GDP。(2)对比三种泰勒规则:钉住非耐用品PPI、钉住加权平均PPI及钉住CPI,福利分析发现钉住非耐用品PPI最优,钉住CPI次之,钉住加权平均PPI的福利损失最大。就损失程度而言,投资专有冲击的福利损失是生产技术冲击的2倍,表明投资专有冲击加剧了最优货币政策在稳定价格与实际GDP间的权衡。
