Painless disinflation? Monetary policy rules in Hungary, 1991‐99

We estimate a small structural model for inflation, the output gap, the domestic interest rate and the exchange rate for Hungary during the period of the transition (1991-99). The transmission of monetary policy impulses to macro variables is characterized in a similar fashion to that of advanced open industrial countries. In particular, in the context of our rational expectations, forward-looking model, the interest rate channel on aggregate demand and the exchange rate channel work together as parts of the same disinflation policy. We draw several conclusions on understanding and modeling the effects of monetary policy, and also on the desirable design of policy rules during the process of disinflation.

Even more on monetary policy in a small open economy

It is well known that in a small open economy with full capital mobility and a fixed exchange rate, monetary policy is ineffective in influencing real output (e.g. the works of Fleming [Int. Monetary Fund Staff Pap. 9 (1962) 369.] and Mundell [Can. J. Econ. Polit. Sci. 29 (1963) 475.]). However, Wu [Int. Rev. Econ. Finance 8 (1999) 223.] finds that when the credit channel is added to this model, monetary policy can have real effects under a fixed exchange rate system. This conclusion hinges on the assumption that open market operations have no effect on foreign exchange reserves of the central bank when evaluating how a change in monetary policy affects the loan market. This assumption is incorrect because under a fixed exchange rate regime, the quantity of foreign reserves becomes endogenous in the model. It is shown that when this assumption is relaxed, monetary policy is still ineffective in influencing output under a fixed exchange regime, even with an operative credit channel.     

Tobin's Q channel and monetary policy rules under incomplete exchange rate pass-through

This paper focuses on the role of the Tobin's Q channel in a two-country framework in which exporting firms set their prices on the basis of local currency pricing. Incomplete exchange rate pass-through significantly affects the Tobin's Q channel in each country compared with the case of complete exchange rate pass-through. We explore whether different specifications of monetary policy enhance social welfare. Regardless of the degree of home bias, a monetary policy rule that stabilizes domestic asset prices attains preferable outcomes to several alternative policy rules considered in our analysis. Notably, there are large gains from employing a domestic asset price rule when the home bias is large. A monetary policy rule that stabilizes the asset prices of both countries results in worse outcomes. Our simulation results suggest that stabilizing asset prices is important in an open economy with incomplete exchange rate pass-through.     

Time-varying transmission efficiency of China’s monetary policy

This paper tries to investigate the time-varying characteristics of China’s monetary policy transmission from the impulse response evidence of both open-economy DSGE model and TVP-VAR model. We find that the transmission efficiency of price-based monetary policy has significantly improved over the sample period, while quantity-based monetary policy is weakening. The resume of exchange reform in 2010 also strengthens the exchange rate channel especially in terms of price-based monetary policy. Combining with the evidence from DSGE model underlines the importance of further interest rate liberalization and price-based monetary policy Taylor rule should also consider the exchange rate stability.     

The role of exchange rate in inflation targeting: the case of Turkey

ABSTRACT

The role of the exchange rates in emerging market economies that have adopted inflation targeting (IT) is a critical and contentious issue in the relevant literature. This article investigates whether an exchange rate-augmented Taylor rule describes the Central Bank of Republic of Turkey’s (CBRT) monetary policy. Covering the period from 2002:1 to 2017:8 it also explores possible nonlinearities in the reaction function of the CBRT by employing a Threshold Vector Autoregressive (TVAR) model. The linear estimation of the model highlighted the importance of the exchange rate in monetary policy under IT. The results of the nonlinear model indicate that the stance of monetary policy was asymmetric with respect to exchange rate movements during the conventional IT period. However, the asymmetric monetary policy stance disappeared in the aftermath of the Global Financial Crisis. Increasing considerations of financial stability undermined the asymmetric policy stance of the CBRT in the post-crisis period.     

How should emerging economies float their currencies?

Floating exchange rates seem to be gaining ground in Latin America, East Asia and the transition economies. The recent crises left many economies with no alternative but to float. Others have moved toward floating, searching for greater flexibility and insulation from external shocks. The question for most emerging market economies, then, is no longer to float or not to float, but how to float. Four issues arise in this regard. The first is how to float and have low inflation. The second is whether floating provides as much insulation as conventional theory predicts, especially in the presence of dollarized liabilities. Which leads to the third point: the relationship between the stability of the exchange rate and that of the financial system. The fourth is how to conduct monetary policy under a float, and the role of inflation targeting. We consider each of these points in turn, and conclude that a workable model of how to float seems to be emerging from the so‐far successful experience of countries like Chile and Brazil. It involves the adoption of an inflation target as the main anchor for monetary policy, coupled with a monetary policy reaction function that — aside from reacting to the output gap and other determinants of the inflation rate — reacts also partially to movements in the nominal exchange rate.

我国货币政策与人民币汇率的互动关系研究

基于SVAR模型研究我国货币政策与人民币汇率的相互作用关系,发现我国货币政策对汇率冲击的反应具有逆经济风向的操作特征,汇率升值,货币政策扩张;而人民币汇率对货币政策冲击的反应也符合经济理论,货币政策扩张会引起人民币汇率贬值。同时,在货币供应量作为货币政策变量时,汇率水平的反应表现为经典的超调现象,但在名义利率作为货币政策变量时,汇率的反应曲线则表现为延迟的超调现象。总体上,我国货币政策对人民币汇率变动非常敏感,相反人民币汇率对货币政策的反应相对较弱。     

Impact of foreign prices and interest rates on canadian economy under alternative monetary and exchange rate regimes

The main objective of this paper is to analyze the impact of U.S. short- and long-term monetary policy under both flexible and managed floating systems, using the new CANDIDE Model 2.0. We have also examined the role of domestic monetary policy in the Canadian economy under both fixed and flexible exchange rate systems. The following are some of the important findings of our study:

1. Our results support the traditional view that under the fixed exchange rate regime, monetary authorities cannot successfully pursue an independent monetary policy from its trading partners — an effort to increase money supply will be almost offset by increases in the balance of payments deficit. In contrast, in the flexible exchange rate regime, monetary policy is more effective in producing an increased growth in output and employment. However the increased output growth comes at the cost of higher prices induced by increased wages and a depreciation of the Canadian dollar.
2. Our results suggest that the impact of U.S. interest rates on investment, GNE, employment, productivity, and government debt is less severe in a pure floating exchange rate regime, compared to the managed floating system. However, the impact of U.S. interest rate policy on the Canadian inflation rate is worse in the case of flexible exchange rate regime. Even though real income and inflation are less favourable in both cases, our results indicate a trade-off between output growth and inflation.
3. Our results imply that under a pure floating monetary authorities can determine the long-run rate of inflation in Canada independent of others. However, the United States and Canadian economies are interrelated during the adjustment process, even under the flexible exchange rates, through the terms of trade and the wage-price spiral channels.

     

Exchange rate management when sterilized interventions represent signals of monetary policy

The signalling channel of foreign exchange market interventions suggests that sterilized interventions represent signals of future monetary policy and thus affect exchange rate expectations. Within a two-country game-theoretic framework, which incorporates two novel factors—partial credibility and non-rational expectations—that reduce the exchange rate effects of intervention operations, I derive non-cooperative and cooperative policies of exchange rate management. To retain credibility in the future, sterilized interventions must be accomodated by corresponding subsequent changes in the money supply. Thus, interventions do not represent an instrument independent from general monetary policy. It is shown that the implied tradeoff between internal and external policy objectives makes the coordination of intervention operations advantageous, even in the case of conflicting exchange rate targets.     

Monetary Policy in Russia: Identifying exchange rate shocks

Russian monetary policy has failed persistently to achieve sustained low inflation, both in absolute terms and relative to the peer group of countries similarly exiting from Soviet-style central planning. This paper explores the reasons for this state of affairs by analysing the kind of monetary policy that has been pursued by the central bank during the period 1995 to 2009. Our contribution is to search for a possible transmission channel between the real interest rate, inflation rate, exchange rate, output growth and foreign reserve growth, after having controlled for the effect of oil price inflation. Using a vector autoregressive model in error-correction form and using sign restrictions methodology, we show that the monetary authorities’ failure to abate double-digit inflation appears to be driven by the policy of exchange rate targeting, as reflected in our identified exchange rate shocks.     

渐进资本开放下中国货币政策的独立性

对中国资本流动程度和中国货币政策独立性的回归检验结果表明:中国的经济实践是符合不可能三角命题的。在1980—2003年间,在事实上钉住美元的固定汇率制度下,中国实行着较为严格的资本管制政策和享有独立的货币政策,但货币政策主要依赖于数量调控工具,汇率和利率的价格调控微乎其微,货币政策的独立性受到极大的挑战。     

外汇冲销式干预对中国货币政策独立性的影响研究

冲销干预对中国货币政策独立性的影响表现出长短期不一致的特征,在短期内有助于保持货币政策的独立性;但在长期内,冲销干预不仅会制约货币政策的操作空间,削弱其独立性,累积金融风险,导致恶性后果。对此,应优化央行票据的期限结构,完善以国债市场为核心的公开市场操作,发展外汇掉期交易,建立外汇平准基金制度,增强货币政策独立性。     

IDENTIFYING THE EFFECTS OF SIMULTANEOUS MONETARY POLICY SHOCKS

Many central banks, particularly in the developing world, aim for exchange rate stability as a macroeconomic goal. However, most are reluctant to relinquish monetary policy autonomy, so they end up operating through both interest rate and foreign exchange interventions. But the use of multiple policy instruments does not necessarily equip monetary authorities with better tools to achieve their targets. On the contrary, their effects can potentially offset each other. Using daily data from the Central Bank of Colombia during the period of 1999–2012, I study the effects of simultaneous policies by first deriving new measures of monetary shocks and then determining their impact on economic activity. The main findings indicate that (a) while interest rate interventions have a significant impact on real and nominal variables, foreign exchange interventions tend to have limited effects; and (b) empirical anomalies, such as the positive relationship between output growth, inflation, and the policy rate are eliminated when properly accounting for the systematic responses of policy.

On discretion versus commitment and the role of the direct exchange rate channel in a forward-looking open economy model

Abstract

This paper compares optimal monetary policy under discretion and commitment in an economy where the direct exchange rate channel is operative. The stabilization bias under discretion is shown to be weaker in an open economy relative to a closed economy. In an open economy, a ‘less conservative central banker’, one that attaches a smaller weight to the variance of inflation in the loss function, can be appointed to replicate the behaviour of real output that eventuates under commitment. Evaluating the social loss function under discretion and commitment, we find that the existence of a direct exchange rate channel in the Phillips Curve mitigates the pronounced differences between the two strategies in case of high persistence in the stochastic shocks.     

EXCHANGE RATE REGIMES AND PASS-THROUGH: EVIDENCE FROM THE TURKISH ECONOMY

We seek to demonstrate the variations in the exchange rate pass-through (ERPT) and identify the shift in the price-setting behavior by placing the emphasis on the implemented exchange rate and monetary policy regimes. Having a history of several distinct monetary regimes, Turkey exhibits a genuine laboratory in this respect. Our empirical results reveal that the pass-through from exchange rates to domestic prices has changed dramatically. We detect breaks in the pass-through coefficients at three episodes, all of which coincide with a shift in monetary/exchange rate regime, lending support to the view that monetary and exchange rate regimes might be among the major determinants of the ERPT process .

Adjustment to monetary policy and devaluation under two-tier and fixed exchange rate regimes

The purpose of this paper is to determine whether a two-tier exchange rate regime is more effective than a fixed rate regime in increasing a country's ability to pursue an independent monetary policy. The analysis compares adjustment to a monetary policy and to a devaluation in the two exchange rate regimes in a portfolio model under imperfect assets substitutability. It is shown that a two-tier exchange rate regime is capable of reducing the current account effects of monetary injection or devaluation only in the long run. In the short run, however, we can get a larger current account response under a two-tier regime. These results reflect the trade-off between quantity and price adjustment.     

Monetary Policy Transmission in Vietnam: Evidence from a VAR Approach

A thorough understanding of the transmission mechanism is a key requirement for central banks for successful implementation of monetary policy. This paper investigates the existence of the interest rate channel, exchange rate channel and asset price channel in Vietnam by employing a vector autoregressive model analysis using monthly data ranging from 2003M1 to 2012M12. The results from the analysis present evidence for a cost channel. However, we find no evidence for the existence of an exchange rate channel or asset price channel of monetary transmission in Vietnam.     

Time inconsistency problems and commitments of monetary and fiscal policies

Within a policy game, where monetary and fiscal authorities are subject to a time inconsistency problem vis-à-vis a monopoly-union, we provide additional support for commitments of either authority: monetary commitment moderates fiscal time inconsistency problems, and fiscal commitment moderates monetary time inconsistency problems. In contrast with the benefits of commitments, a regime of coordinated monetary and fiscal policy may turn out to be counterproductive.Comments and suggestions from Torben M.

INSIDE THE IMPOSSIBLE TRIANGLE: MONETARY POLICY AUTONOMY IN A CREDIBLE TARGET ZONE

This paper examines the trade-off between exchange rate stability and monetary autonomy for a target zone. Using the guilder-mark target zone in the pre-Economic and Monetary Union period as a case study, we empirically estimate how much policy discretion the Dutch central bank still enjoyed and how much had been ceded to the German central bank. The sum of these two measures is an estimate of the policy autonomy under a free float. We find that the narrow guilder-mark target zone still permitted a modest degree of policy independence. This result suggests that intermediate exchange rate regimes may offer an attractive trade-off compared to the corner solutions (free float and monetary union), which is consistent with the "fear of floating" phenomenon.
