Unification and the policy predicament in Germany

We argue that wages have increased so far ahead of labour productivity in east Germany as to produce a problem that will continue to hound German policy-makers for the next two decades. Despite rapid rates of capital accumulation (around 9%) and growth (around 5%) in east Germany over the coming 10 years, our estimates show that even if wage catch-up decelerates greatly, as long as it continues, the rate of unemployment in the east will still be twice as high as in the west in another 10 years. Alternatively, if wage discipline forces the eastern unemployment rate to come down to the western level, wage differentials will widen substantially over these next 10 years. Thus serious problems loom ahead.     

Monetary policy design and transmission asymmetry in EMU: Does uncertainty matter?

In this paper, we consider how uncertainty affects the choice between federal monetary policy based on national and union-wide aggregate data under conditions of asymmetry in the transmission of monetary policy. We find that the uncertainty about the transmission process sustains (and, in some cases, even reinforces) the need to take into account information about national economies in the formulation of monetary policy. Also the forecasting process matters when uncertainty is additive: in particular, when union-wide forecasting is more accurate than national-based forecasting, this advantage can compensate for the welfare loss from using union-wide aggregation. There is, however, a strong case for using national information in the optimal design of common monetary policy.     

Monetary integration,soft budget constraints,and the EMU sovereign debt crises

One possible explanation for the European sovereign debt crises is that the European Economic and Monetary Union (EMU) gave rise to consolidation fatigue or even deliberate over‐borrowing. This paper explores the validity of this explanation by studying how three decisive stages in the history of the EMU affected public borrowing in EU member states: the signing of the Maastricht Treaty, the introduction of the Euro, and the suspension of the Stability and Growth Pact (SGP). The methodology relies on difference‐in‐difference regressions for 26 OECD countries over the 1975–2009 period. The findings indicate that the Maastricht treaty reduced deficits especially in traditionally high‐deficit countries. In contrast, the introduction of the Euro and the watering down of the original SGP led on average to higher borrowing. These results indicate that the introduction of the Euro and the suspension of the SGP led to soft budget constraints in the EMU.     

Monetary policy, oil shocks, and TFP: Accounting for the decline in US volatility

An equilibrium model is used to assess the quantitative importance of monetary policy for the post-1984 decline in US inflation and output volatility. The principal finding is that monetary policy played a substantial role in reducing inflation volatility, but a small role in reducing real output volatility. The model attributes much of the decline in real output volatility to smaller TFP shocks. We also investigate the pattern of output and inflation volatility under an optimal monetary policy counterfactual. We find that real output volatility would have been somewhat lower, and inflation volatility substantially lower, had monetary policy been set optimally.     

Challenges for International Economic Policy Coordination in EMU: Institutional Setting, Financial Market Reactions and the Importance of Systemic Risk

The launch of the euro and, with it, the institutional framework that has been established are raising a number of important issues for the co-ordination of policies, not only within EMU, but also with countries outside the euro area. This paper looks at some of the challenges that the institutions and processes put in place for conducting policy in the euro area pose for international co-ordination. More precisely, it assesses whether there are risks that the new institutional arrangements may generate more imbalanced policies than earlier, thereby creating negative international spillovers. This paper also discusses whether these arrangements may create new systemic risks in international financial markets.Counsellor for Macroeconomic Policies     

Monetary policy before and after the euro: evidence from Greece

We model Greek monetary policy in the 1990s and use our findings to address two interrelated questions. First, how was monetary policy conducted in the 1990s so that the hitherto highest-inflation EU country managed to join the euro by 2001? Second, how compatible is the ECB monetary policy with Greek economic conditions? We find that Greek monetary policy in the 1990s was: (i) primarily determined by German/ECB interest rates, though still influenced by domestic fundamentals; (ii) involving non-linear output gap effects; (iii) subject to a deficit of credibility culminating in the 1998 devaluation. On the question of compatibility our findings depend on the value assumed for the equilibrium post-euro real interest rate and overall indicate both a reduction in the pre-euro risk premium and some degree of monetary policy incompatibility. Our analysis has policy implications for the new EU members and motivates further research on fast-growing EMU economies.     

Monetary policy, macroeconomic adjustment and currency speculation under floating exchange rates: the case of Bulgaria

This paper deals with the Bulgarian experience with exchange rate policy and the related macroeconomic adjustment in the transition period. It is argued that in the context of the Bulgarian macroeconomic environment, the exchange rate regime and the exchange rate policy (or the lack of such) did play a crucial role in determining the patterns of macroeconomic adjustment in this period. A simple general equilibrium model is suggested that provides some insights into the stylized performance of an economy under certain assumptions, similar to those characterizing the transitional state of the Bulgarian economy. Finally, some aspects of Bulgarian macroeconomic performance in recent years are analysed on the basis of the available empirical information and using the framework of the theoretical model. The paper concludes with the policy lessons of this experience.     

Fiscal policy,macroeconomic performance and industry structure in a small open economy

We analyse how fiscal policy affects both the macroeconomy and the industry structure, using a multi-sector macroeconomic model of the Norwegian economy with an inflation targeting monetary policy. Our simulations show that the magnitude of the government spending and labour tax cut multipliers, whether monetary policy is active or passive, is comparable to what is found in the literature. A novel finding from our simulations is that the industry structure is substantially affected by an expansionary fiscal policy, as value added in the non-traded goods sector increases at the expense of value added in the traded goods sector. Moreover, expansionary fiscal policy reduces the mark-ups in the traded goods sector, while the mark-ups are roughly unchanged in the non-traded goods sector. The contraction of activity in the traded goods sector increases when monetary tightening accompanies the fiscal stimulus. Hence, we find that such a policy mix is likely to produce significant de-industrialization in a small open economy with inflation targeting.     

Oil shocks,policy uncertainty and stock returns in China

This paper examines the interdependence of China's policy uncertainty, the global oil market and stock market returns in China. A structural VAR model is estimated that shows that a positive shock to economic policy uncertainty in China has a delayed negative effect on global oil production, real oil prices and real stock market returns. Shocks to oil market‐specific demand significantly raise China's economic policy uncertainty and reduce the real stock market returns. As measured by a spillover index, the interdependence between these variables has been rising since 2003 as China's influence in the oil market has increased. An equivalent spillover index calculated for the US is smaller and has been largely flat over time.     

US monetary policy shocks and the Chinese economy: a GVAR approach

Using a global vector auto regressive (GVAR) methodology, this article examines the impact of US monetary policy shocks on China’s major macroeconomic indicators. Our analysis reveals that a positive shock to the US money supply growth rate initially increases China’s inflation rate but after some time this effect completely disappears. This shock also raises China’s short-term interest rate and the Chinese currency appreciates against the US dollar. A positive shock to the US short-term interest rate increases China’s short-term interest rate but the real output growth and inflation rates decline and the Chinese currency appreciates.     

Monetary and fiscal policy interactions in the EMU when cyclical conditions are uncertain

This paper examines economic policy interactions in the Economic and Monetary Union when the assessment of cyclical conditions in real time is surrounded by uncertainty. On the basis of a simple stylised model it shows that with a Nash-type of interaction different views about the output gap on the side of the policy players—the Council of the European Union, the European Commission and the European Central Bank—can give rise to excessive activism with policy players pushing economic variables into opposite directions. It argues that the costs of such policy conflicts can be reduced by agreeing on a common assessment of the cycle, by constraining policy variables, and/or by increasing the weight of fiscally conservative institutions. An alternative option to sidestep policy conflicts ensuing from diverging views of the cycle is to take policy decisions sequentially, as is the case in a Stackelberg-type of interaction. The paper shows that for a given misperception of the cycle, the impact on the policy instruments and on output and inflation are generally smaller in the Stackelberg equilibrium as compared to a Nash outcome. Alternative allocations of roles—that is leader versus follower—are discussed and assessed.

Macroeconomic impacts of fiscal policy shocks in the UK: A DSGE analysis

This paper develops and estimates a new-Keynesian dynamic stochastic general equilibrium (DSGE) model for the analysis of fiscal policy in the UK. We find that government consumption and investment yield the highest GDP multipliers in the short-run, whereas capital income tax and public investment have dominating effect on GDP in the long-run. When nominal interest rate is at the zero lower bound, consumption taxes and public consumption and investment are found to be the most effective fiscal instruments throughout the analysed horizon, and capital and labour income taxes are established to be the least effective. The paper also shows that the effectiveness of fiscal policy decreases in a small open-economy scenario and that nominal rigidities improve effectiveness of public spending and consumption taxes, whereas decrease that of income taxes.     

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.     

To react or not? Technology shocks, fiscal policy and welfare in the EU-3

This paper develops a dynamic stochastic general equilibrium (DSGE) model to examine the quantitative macroeconomic implications of counter-cyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity and consumption habits, as the particular market failures justifying policy intervention. We subject the model to productivity shocks and allow policy instruments to react to the output gap and the debt-to-output ratio. A welfare analysis reveals that the most effective instrument-target combination is to use public consumption to stabilize the output gap. Moreover, welfare gains from counter-cyclical fiscal policy are much stronger in the presence of wage rigidities compared with consumption habits. Finally, since active policy and automatic stabilizers are substitutes, it is possible that relatively undistorted economies may be in need of countercyclical fiscal action due to inadequate automatic stabilizers.     

Monetary policy shocks and productivity measures in the G-7 countries

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.

Unemployment dynamics in emerging countries: Monetary policy and external shocks

This paper quantifies the impact of three key external shocks – external demand, interest rate, and uncertainty shocks – on emerging market economies (EMEs). We find that external shocks have a sizeable impact on macroeconomic fluctuations in EMEs and that a considerable fraction of this impact is through the domestic stock market. A decrease in external demand and an increase in external interest rate and uncertainty lead to a higher unemployment rate, lower stock market return, and a depreciation of the domestic currency. The EMEs' monetary policy actively responds to external shocks and dampens their impact on domestic activity.     

Unconventional monetary policy announcements and information shocks in the U.S.

We study unconventional policy shocks and information shocks associated with central bank announcements in the U.S. While unconventional policy shocks capture the direct influence of announced monetary policy actions, information shocks are associated with central bank information conveyed with the announcement. To disentangle these two types of shocks, we impose sign restrictions on high frequency changes in interest rates and stock prices around announcements. We find that information shocks lead to persistent declines in the 10-year government bond yield, whereas the actual unconventional policy shock induces only small interest rate responses. We also find that expansionary output effects of unconventional monetary policy are to some extent counteracted by the information shock.     

Oil shocks and fiscal policy procyclicality in Angola: Assessing the role of asymmetries and institutions

The aim of this article is to examine procyclicality in Angola, assess whether it behaves asymmetrically over the oil cycle, and test the hypothesis that institutions and fiscal rules can moderate procyclicality. Received wisdom suggests that in resource‐rich economies, fiscal policy tends to be procyclical albeit improvements in the past decades due to institutional reforms. Similar evidence is available for oil‐rich economies; however, we know little about how procyclicality behaves over the oil cycle; that is, whether spending (and revenue) grows faster during oil‐market booms, than during downturns. Further, evidence on institutions and fiscal rules in oil‐exporting economies is still ambiguous. We bridge both gaps by examining fiscal policy procyclicality in Angola, one of the largest oil‐producers in Africa, and a country that has experienced an intense process of institutional reforms since 2002. Therefore, it is an ideal candidate for our study. We use data for the 2004–2014 period to estimate a threshold vector error correction model that extends vector autoregressive and vector correction methods used up to date. Our results indicate that revenue and spending are generally procyclical to oil shocks, that revenue is more procyclical during booms, and that institutional quality, net inflows, financial openness, and fiscal rules affect procyclicality.     

Hyperinflation in Zimbabwe: money demand,seigniorage and aid shocks

Zimbabwe experienced record hyperinflation of 80 billion per cent per month in 2008. This article uses new data from Zimbabwe to investigate money demand under hyperinflation using an autoregressive distributed-lag model for the period 1980–2008. The results produce plausible convergence rates and long-run elasticities, indicating that real-money balances are cointegrated with the inflation rate and signifying an equilibrium relationship between the two series. Evidence is also presented suggesting prices were driven by increases in the money supply rather than by changes in price setting behaviour. The article uses the estimated elasticity on the inflation variable to calculate the maximum level of seigniorage revenue that could be raised in the economy. Actual seigniorage levels increased dramatically after 2000, with inflation eventually exceeding the rate required to maximize this revenue stream. This is discussed in relation to international financing constraints and the collapse of the domestic tax base.
