Global impact of a shift in foreign reserves to euros

This paper uses QUEST III, a multi-region DSGE model, to study the macroeconomic effects of a gradual equalization of official foreign reserves between dollars and euros. We simulate a scenario of a shift in the composition of foreign reserves holdings from the present ratio of 65% dollars and 25% euros to equal 45% shares over a 10 years period. We assume imperfect substitutability between financial assets to allow this shift to have real effects. Our simulations point towards small real effects due to the reduction in real interest rates resulting from this shift in official holdings.

The effect of monetary policy on output in EMU3: A sign restriction approach

This paper examines the effects of monetary policy shocks on output in the three largest euro area economies – Germany, France and Italy (EMU3) – by applying a new VAR identification procedure. The results show that monetary policy innovations are at their most potent in Germany. However, apart from Germany, it remains ambiguous as to whether a rise in interest rates concludes with a fall in output, showing a lack of homogeneity in the responses. Homogeneity in response to a monetary shock is crucial in a one-size-fits-all framework. Nonetheless, the lack of similarity between the responses, which is hypothesised to cause de-synchronised business cycles in optimal currency area literature, is often based on the premise that monetary policy itself is a major source of business cycle fluctuations. This paper concludes that monetary policy innovations play, at most, a modest role in generating fluctuations in output for the EMU3. Consequently, it is less important whether the effects of monetary policy are homogenous.     

Optimal fiscal policy in a world liquidity trap

We construct a model of the international transmission of ‘liquidity trap’ shocks, and examine the case for international coordination of fiscal policy to respond to the liquidity trap. Integrated financial markets tend to propagate liquidity traps. In a global environment, fiscal policy may be effective in raising GDP when the economy is stuck in a liquidity trap, but it does so in a ‘beggar thy neighbor’ fashion; when one economy is in a liquidity trap, the cross country spillover effect of fiscal policy is negative. We examine the welfare optimizing policy response to a liquidity trap when countries coordinate on fiscal policy. Fiscal policy may be an effective tool in responding to a liquidity trap, although it is never optimal to use fiscal expansion sufficiently to fully eliminate a downturn. Moreover, there is little case for coordinated global fiscal expansion. For the most part, the country worst hit by a liquidity trap shock should use its own policies to respond, without much help from foreign policies.     

EMU and the transmission of monetary policy: evidence from business lending rates

This paper analyses the pass-through of money market rates to short-term and long-term business lending rates in the four largest euro area countries. The main findings of the paper are (1) that since the start of EMU loan rates appear to have become more responsive to money market rate changes in France, Italy and Spain, but not in Germany, and (2) that German loan rates are significantly more sluggish than loan rates in the other three large euro area countries. I also test for non-linear pass-through based on an asymmetric error-correction model but do not find much evidence of non-linearity in euro area interest rate pass-through.The views expressed in this paper do not necessarily represent the views of the Deutsche Bundesbank.     

Euro area inflation persistence

This paper presents evidence on the lag between monetary policy actions and the response of inflation in the euro area as a whole as well as in some of its core countries, notably Germany, Italy and France. In line with previous findings for the US and the UK, results here show that it takes over a year before monetary policy actions have their maximum effect on inflation both in the euro area and in individual countries and that a lag of this length has existed in Europe at least since the collapse of the Bretton Woods system, despite the numerous changes in European monetary policy regime thereafter. Results based on alternative definitions of inflation persistence support these findings and indicate, if any, that transmission lags could be in fact much longer for individual countries and the euro area as a whole, although, at the country level, there is strong evidence over time of a drop in German inflation persistence and a sizeable shift in the mean of inflation – particularly in Italy and France. An examination based on results from this paper reveals that euro area inflation persistence could well be an intrinsic phenomenon rather than a ‘statistical fluke’ due to aggregation.This research was conducted during my visit at the European Central Bank Directorate Research, as part of the Research Visitor Programme.

China’s monetary policy: Quantity versus price rules

Two monetary policy rules, the money supply (quantity) rule and interest rate (price) rule, are explored for China in a dynamic stochastic general equilibrium model. The empirical results seem to indicate that the price rule is likely to be more effective in managing the macroeconomy than the quantity rule, favoring the government’s intention of liberalizing interest rates and making a more active use of the price instrument. Moreover, the economy would have experienced less fluctuations had interest rate responded more aggressively to inflation.     

South Africa’s monetary policy independence: evidence from a Global New-Keynesian DSGE model

We study the response of South African monetary policy decisions to foreign monetary policy shocks. We estimate the extent of foreign monetary policy pass through by augmenting standard Taylor rules and comparing the results within the context of a Global New-Keynesian Dynamic Stochastic General Equilibrium (DSGE) model. The general equilibrium model captures important spill-over effects that would otherwise have been ignored in a single equation set-up. The results show that the relationship between foreign monetary policy shocks and South African interest rates is complicated – South Africa does not import foreign monetary policy directly, but is still affected. Except for the US, an increase in foreign interest rates leads to a decrease in South African interest rates – highlighting the complex channels that the monetary policy authority has to monitor outside of its economy.     

An estimated two-country DSGE model of Austria and the Euro Area

We present a two-country New Open Economy Macro model of the Austrian economy within the European Union’s Economic & Monetary Union (EMU). The model includes both nominal and real frictions that have proven to be important in matching business cycle facts, and that allow for an investigation of the effects and cross-country transmission of a number of structural shocks: shocks to technologies, shocks to preferences, cost-push type shocks and policy shocks. The model is estimated using Bayesian methods on quarterly data covering the period of 1976:Q2–2005:Q1. In addition to the assessment of the relative importance of various shocks, the model also allows to investigate effects of the monetary regime switch with the final stage of the EMU and investigates in how far this has altered macroeconomic transmission. We find that Austria’s economy appears to react stronger to demand shocks, while in the rest of the Euro Area supply shocks have a stronger impact. Comparing the estimations on pre-EMU and EMU subsamples we find that the contribution of (rest of the) Euro Area shocks to Austria’s business cycle fluctuations has increased significantly.

Is East Asia an optimum currency area?

This paper assesses the empirical desirability of the East Asian economies to an alternative exchange rate arrangement (a monetary union) that can potentially enhance the exchange rate stability and credibility in the region. Specifically, the symmetry in macroeconomic disturbances of the East Asian economies is examined as satisfying one of the preconditions for forming an Optimum Currency Area (OCA). We extend the existing literature by improving the methodology of assessing the symmetry shocks in evaluating the suitability of a common currency area in the East Asian economies employing the Bayesian State-Space Based approach. We consider a model of an economy in which the output is influenced by global, regional and country-specific shocks. The importance of a common regional shock would provide a case for a regional common currency. This model allows us to examine regional and country-specific cycles simultaneously with the world business cycle. The importance of the shocks decomposition is that studying a subset of countries can lead one to believe that observed co-movement is particular to that subset of countries when it in fact is common to a much larger group of countries. In addition, the understanding of the sources of international economic fluctuations is important for making policy decisions. The falling share of country specific factor and the rising role of region factor indicate that East Asia has become increasingly favorable for a monetary union. However, the share of country-specific factor that is still significant implies that it could be costly to renounce individual currencies to advance into a monetary union in East Asia.     

现行国际货币体系与我国货币供给内生性

基于后凯恩斯主义的内生货币供给理论,本文重点从基础货币的角度分析了我国货币供给的内生性,主要结论是:1994年以前,"对金融机构债权"项目的变动是导致我国基础货币投放具有内生性的主要原因,而从1994年开始特别是在2002年以后,则由"国外资产净额"项目即外汇占款的增加主导了我国基础货币的被动投放.进而影响了中央银行对货币供应量的控制能力,使我国货币政策的传导在起点上就缺乏有效性.在现行的国际货币体系下,为减轻货币内生性带来的影响、提高货币政策的有效性,我国应加速人民币国际化进程和建立更具弹性的汇率制度.
