The paper considers the connection between exchange rate regimes and economic performance as measured by inflation, output growth, and their volatility. It is argued first that the choice of an intermediate exchange rate regime is complicated by potential conflicts with the requirements of central bank transparency and accountability. These are considered to be longer run questions. Next, three types of managed floating regimes are defined. A variety of counterfactual experiments are shown to illustrate that a managed float, such that the objective of monetary policy is expressed in terms of an inflation target, will produce the most desirable macroeconomic outcome. The counterfactuals are supplemented with estimates of forward-looking Taylor rules to ascertain whether such rules are informative under a managed floating scenario. In general, the answer is that central bank reaction functions become less useful when the exchange rate regime is an intermediate one. 相似文献

基于由贝叶斯技术估计的新凯恩斯动态随机一般均衡(DSGE)模型,识别和分析货币供给与货币需求冲击对产出和通货膨胀波动的影响,结果表明:货币供给冲击对产出和通货膨胀波动均能够产生同向影响,但对产出波动的影响不明显,仅能解释其不足2%的波动,而对通货膨胀波动的影响比较强,长期内可以解释其26%以上的波动;货币需求冲击对产出和通货膨胀波动的影响都不明显,长期内对二者波动的解释能力均低于0.6%。因此,在应对通胀压力时,央行可以运用数量型货币政策工具,对高通胀势头实施积极的紧缩性宏观调控。 相似文献

This study investigates the determinants of variations in the yield spreads between Japanese yen interest rate swaps and Japan government bonds for a period from 1997 to 2005. A smooth transition vector autoregressive (STVAR) model and generalized impulse response functions are used to analyze the impact of various economic shocks on swap spreads. The volatility based on a GARCH (generalized autoregressive conditional heteroskedasticity) model of the government bond rate is identified as the transition variable that controls the smooth transition from a high volatility regime to a low volatility regime. The break point of the regime shift occurs around the end of the Japanese banking crisis. The impact of economic shocks on swap spreads varies across the maturity of swap spreads as well as regimes. Overall, swap spreads are more responsive to the economic shocks in the high volatility regime. Moreover, a volatility shock has profound effects on shorter maturity spreads, whereas the term structure shock plays an important role in impacting longer maturity spreads. Results of this study also show noticeable differences between the nonlinear and linear impulse response functions. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:82–107, 2008 相似文献

This paper develops a basic model for output fluctuations in traded and non-traded sectors under two alternative monetary policy regimes; exchange rate targeting (or monetary union) and inflation targeting. The conventional wisdom from one-sector models says that inflation targeting gives better output stabilization than exchange rate targeting when demand shocks occur, but the opposite when supply shocks occur. In a model with a traded and a non-traded sector, we show that the conventional wisdom holds for the non-traded sector. However, for the traded sector, we show that inflation targeting destabilizes output compared with exchange rate targeting when both supply and demand shocks occur. The only shocks where inflation targeting provides the better output stability for the traded sector are shocks to world market prices. The two-sector structure introduces new mechanisms that may turn around earlier results for aggregate production. For instance, a demand shock may induce higher aggregate output fluctuations with inflation targeting than with exchange rate targeting. Furthermore, a positive demand shock may prove to be contractionary under inflation targeting. 相似文献

在“三重压力”下,我国货币政策调控要实现“稳增长”和“防通胀”在水平值和波动率上的“双重稳定”,既要保持适度经济增速,又要防止通货膨胀快速上升,还要防止产出和通胀波动形成的经济风险。为此,文章使用了局部投影方法和VAR模型方法计算了数量型和价格型货币政策的冲击反应函数,以此刻画货币政策对产出增长率和通货膨胀率的水平值和波动率的动态效应。实证结果表明,数量型货币政策对经济增长率和通货膨胀率均具有水平值上的显著正向效应,同时具有降低产出波动而提升通胀波动的冲击效应;价格型货币政策也对经济增长率和通货膨胀率具有显著正向效应,同时具有降低产出波动率和通胀波动率的双重稳定功能。因此,当前货币政策操作仍然要以价格型货币政策为主,以此实现货币政策逆周期和跨周期调控功能。 相似文献

Monetary policy and welfare in a small open economy 总被引:1,自引:0,他引:1

This paper analyzes optimal monetary policy in a small open economy featuring monopolistic competition and nominal rigidities. It shows that the utility-based loss function for this economy can be written as a quadratic expression of domestic inflation, output gap and real exchange rate. The presence of an internal monopolistic distortion and a terms of trade externality drives optimal policy away from domestic inflation targeting and affects the optimal level of exchange rate volatility. When domestic and foreign goods are close substitutes for each other, the optimal policy rule implies lower real exchange rate volatility than a domestic inflation targeting regime. The reverse is true when the elasticity of substitution between goods is low. 相似文献

This study investigated the volatility linkages between energy and agricultural futures, including possible causes for these comovements, such as external macroeconomic and financial shocks during low and high volatility regimes. A combination of Markov-switching regressions and quadrivariate VAR–DCC–GARCH and VAR–BEKK–GARCH modeling revealed that external shocks have an asymmetric effect on the relationship of these assets with higher cross-correlations reported during high volatility regimes. This comovement effect outweighs the substitution effect between energy and agricultural products. Furthermore, the quadrivariate VAR–BEKK–GARCH model provides strong evidence of a bidirectional price volatility spillover between the agricultural and energy markets during periods of high volatility. Overall, the results suggest that energy futures can be effectively used for hedging in a portfolio comprising agricultural futures (and vice versa), while a combination of macroeconomic and financial index futures can serve as an effective hedging tool in investment portfolios comprising both energy and agricultural commodities. 相似文献

The past two decades have witnessed a worldwide move by emerging markets to adopt explicit or implicit inflation targeting regimes. A notable and often discussed exception to this trend, of course, is China which follows a pegged exchange rate regime supported by capital controls. Another major exception is India. It is not clear how to characterize the monetary regime or identify the nominal monetary anchor in India. Is central bank policy in India following a predictable rule that is heavily influenced by a quasi inflation target? And how has the monetary regime been affected by the gradual process of financial liberalization in India? To address these points, we investigate monetary policy regime change in India using a Markov switching model to estimate a time-varying Taylor-type rule for the Reserve Bank of India. We find that the conduct of monetary policy over the last two decades can be characterized by two regimes, which we term ‘Hawk’ and ‘Dove.’ In the first of these two regimes, the central bank reveals a greater relative (though not absolute) weight on controlling inflation vis-à-vis narrowing the output gap. The central bank however was found to be in the “Dove” regime about half of our sample period, focusing more on the output gap and exchange rate targets to stimulate exports, rather than moderating inflation. India thus seems to be following its own direction in the conduct of monetary policy, seemingly not overly influenced by the emphasis on quasi-inflation targeting seen in many emerging markets. 相似文献

We characterize the dynamics of the US short‐term interest rate using a Markov regime‐switching model. Using a test developed by Garcia, we show that there are two regimes in the data: In one regime, the short rate behaves like a random walk with low volatility; in another regime, it exhibits strong mean reversion and high volatility. In our model, the sensitivity of interest rate volatility to the level of interest rate is much lower than what is commonly found in the literature. We also show that the findings of nonlinear drift in Aït‐Sahalia and Stanton, using nonparametric methods, are consistent with our regime‐switching model. 相似文献

Using disaggregated data for the United States, this paper explores the effects of the variability of fiscal and monetary policy shocks. Higher variability of government spending shocks around a steady-state growth trend results in, on average, a decline in aggregate demand growth and inflation, with limited effects on output growth. On the other hand, higher variability of monetary shocks results in, on average, an increase in inflation and a decline in output growth. These results indicate the desirability of avoiding large fluctuations over time in either government spending or the money supply. 相似文献

This paper analyzes exchange rate turmoil with a Markov switching GARCH model. We distinguish between two different regimes in both the conditional mean and the conditional variance: “ordinary” regime, characterized by low exchange rate changes and low volatility, and “turbulent” regime, characterized by high exchange rate devaluation and high volatility. We also allow the transition probabilities to vary over time as functions of economic and financial indicators. We find that real effective exchange rates, money supply relative to reserves, stock index returns, and bank stock index returns and volatility contain valuable information for identifying turbulent and ordinary periods. 相似文献

Did the gold standard diminish macroeconomic volatility? Supporters thought so, critics thought not, and theory offers ambiguous messages. Hard regimes like the gold standard limit monetary shocks by tying policymakers' hands; but exchange-rate inflexibility compromises shock absorption in a world of real disturbances and nominal stickiness. A model shows how lack of flexibility affects the transmission of terms-of-trade shocks. Evidence from the late nineteenth and early twentieth century exposes a dramatic change. The classical gold standard did absorb shocks, but the interwar gold standard did not, supporting the view that the interwar gold standard was a poor regime choice. 相似文献

As the Fed begins to wrestle with how to stimulate growth in the next economic downturn in an environment of low interest rates, a number of possible changes in its policy framework are being entertained. One in particular that has gained considerable support is price-level targeting, based on the view that this approach would tend to move inflation and nominal interest rates up late in the business cycle, yielding more room for rate cuts when the downturn ensues. We outline the inherent difficulties involved in controlling the level of inflation under the current inflation-targeting regime. We then argue that requiring the Fed to meet the more stringent objective of a price-level target could introduce significantly greater volatility into output growth—potentially worsening economic downturns—than is the case under the current policy framework. We also consider a preferred course of action that adds a bit more flexibility to the current framework, at least for the near to the medium term, and how the Fed might deal with the next recession. 相似文献

Responses of inflation and non‐oil output growth from the Gulf Cooperation Council (GCC) countries to monetary policy shocks from the United States (US) were estimated to determine whether there is evidence to support the US dollar as the anchor for the proposed unified currency. A structural vector autoregression identified with short‐run restrictions was employed for each country with Fed funds rate as the US monetary policy instrument, non‐oil output growth and inflation. The main results suggest that for inflation, the GCC countries show synchronised responses to monetary policy shocks from the US which are similar to inflation in the US, and for non‐oil output growth, there is no clear indication that US monetary policy can be as effective for the GCC countries as it is domestically. Consequently, importing US monetary policy via a dollar peg may guarantee only stable inflation for the GCC countries – not necessarily stable non‐oil output growth. If the non‐oil output response is made conscientiously – and there are concerns over the dollar’s ability to perform its role as a store of value – a basket peg with both the US dollar and the euro may be a sound alternative as confirmed by the variance decomposition analysis of our augmented SVAR with a proxy for the European short‐term interest rate. 相似文献

ABSTRACTThe impact of dollarization on domestic economic performance, and the welfare implications of high inflation in an inflation targeting environment, have remained a matter of much concern for policymakers in recent years. This study investigates the effects of dollarization on inflation and inflation uncertainty in Ghana for the period January 1990 to December 2017. We apply the exponential Generalized Autoregressive Conditional Heteroskedasticity model together with impulse response and Granger causality tests to explore how dollarization affects the behavior of inflation for the pre-inflation targeting period (January 1990 – May 2007) and post-inflation targeting period (June 2007 – December 2017). The results indicate that dollarization has not played a significant role in the volatility of inflation in Ghana. Also, inflation Granger causes dollarization in both the pre- and post-inflation targeting regimes. Finally, there is a bidirectional causal relationship between inflation and inflation uncertainty following the adoption of inflation targeting monetary policy. We conclude that, although inflation targeting has not presented a significant impact on inflation volatility, it has affected the relationship between inflation and inflation uncertainty in Ghana. The dynamics of inflation volatility and asymmetries present crucial implications which are discussed to guide policymaking. 相似文献

What drives exchange rate volatility, and what are the effects of fluctuations in the exchange rate on economic growth in Ghana? These questions are the subject matter of this study. The results showed that while shocks to the exchange rate are mean reverting, misalignments tend to correct very sluggishly, with painful consequences in the short run as economic agents recalibrate their consumption and investment choices. About three quarters of shocks to the real exchange rate are self-driven, and the remaining one quarter or so is attributed to factors such as government expenditure and money supply growth, terms of trade and output shocks. Excessive volatility is found to be detrimental to economic growth; however, this is only up to a point as growth-enhancing effect can also emanate from innovation, and more efficient resource allocation. 相似文献

We investigate bivariate regime‐switching in daily futures‐contract returns for the US stock index and ten‐year Treasury notes over the crisis‐rich 1997–2005 period. We allow the return means, volatilities, and correlation to all vary across regimes. We document a striking contrast between regimes, with a high‐stress regime that exhibits a much higher stock volatility, a much lower stock–bond correlation, and a higher mean bond return. The high‐stress regime is associated with higher average values of stock‐implied volatility, stock illiquidity, and stock and bond futures trading volume. The lagged implied volatility from equity‐index options is useful in modeling the time‐varying transition probabilities of the regime‐switching process. Our findings support the notions that: (1) stock market stress can have a material influence on Treasury bond pricing, and (2) the diversification benefits of combined stock–bond holdings tend to be greater during times with relatively high stock market stress. © 2009 Wiley Periodicals, Inc.

China's GDP growth slowdown and a surge in global financial market volatility could both adversely affect an already weak global economic recovery. To quantify the global macroeconomic consequences of these shocks, we employ a GVAR model estimated for 26 countries/regions over the period 1981Q1 to 2013Q1. Our results indicate that (i) a one percent permanent negative GDP shock in China (equivalent to a one-off one percent growth shock) could have significant global macroeconomic repercussions, with world growth reducing by 0.23 percentage points in the short-run; and (ii) a surge in global financial market volatility could translate into a fall in world economic growth of around 0.29 percentage points, but it could also have negative short-run impacts on global equity markets, oil prices and long-term interest rates. 相似文献

This paper investigates the relationship between terms-of-trade shocks and macroeconomic volatility for a panel of 58 developing countries from 1980 to 2015. Using a Panel Smooth Transition Regression model, we prove first, that terms-of-trade volatility have a statistically significant and positive impact on the volatility of output growth, although the magnitude of this effect is not the same by the report to the threshold that has been identified. Second, the terms-of-trade volatility affect macroeconomic fluctuation differently depending on whether the country is a net exporter of the commodity, fuel or manufactured goods. 相似文献

This paper examines the impact of collapsing fixed, permanently fixed, and flexible exchange rate regimes on real output. Much of the recent discussion of the causes of exchange rate regime collapses has focused on capital flows and export demands. In an environment in which such external shocks predominate, a flexible exchange rate is shown theoretically to produce lower output variability for a range of parameter values. A counterfactual exercise is performed using Mexican data. We find that had Mexico been on a flexible rate for the past two decades, the variance of real output would have been reduced by half. 相似文献
