  This note argues that basically all strands of available empirical and quantitative evidence on the economic effects of Brexit arrive at the conclusion that the economic burden for Britain will be substantial. Furthermore, there are good reasons to expect that these costs are currently even underestimated as dynamic effects of Brexit are insufficiently captured by existing methods. Furthermore, all scenarios assume an orderly Brexit which looks increasingly unlikely. The best way forward is an exit from Brexit and to call for a second referendum on the concrete two policy alternatives which are now on the table.

  Brexit, the exit of Britain from the EU, is scheduled to happen on March 29, 2019. At present, the Brexit train seems almost unstoppable. While most earlier economic and political discussions centered around the concrete design of Brexit and the impact of different arrangements of economic integration in the post-Brexit period (“soft” versus “hard” Brexit), the most pressing question now is whether an orderly Brexit can still be accomplished.

  Numerous econometric studies fail to detect a significant and robust relationship between international aid and economic growth in the recipient countries. Dutch Disease effects might be responsible for this result. This paper examines the relation between aid and its effectiveness in a multi-sector multi-household Computable General Equilibrium (CGE)-framework. Given that international transfers to African countries increasingly take the form of general financial support to the government, different spending strategies and their macroeconomic, sectoral and distributional effects are evaluated in a two-stage simulation making a distinction between immediate direct effects and possible long-run effects from increased productivity. The presence of sector-specific factors weakens Dutch Disease effects and shifts the burden of adjustment primarily to other exporting sectors. While the model simulates the effects of additional aid in Zambia it can be used as a blueprint for other African countries.

  Dieser Beitrag untersucht die dynamischen Effekte antizipierter und nicht-antizipierter Ölpreiserhöhungen in einer kleinen Währungsunion mit zwei Mitgliedsländern, die gleichzeitig durch asymmetrische Lohnanpassungsgleichungen und asymmetrische Zinsreagibilitäten der Güternachfrage gekennzeichnet sind. In dieser strukturell asymmetrischen Währungsunion führen gemeinsame externe Ölpreisschocks zu vorübergehenden konjunkturellen Divergenzen innerhalb der Währungsunion. Im Fall antizipierter Ölpreiserhöhungen kommt es im Verlauf des Anpassungsprozesses zu einer Umkehrung des Konjunkturgefälles innerhalb der Währungsunion. Die Stabilisierung der Outputentwicklungen innerhalb der Währungsunion ist über den gesamten Zeitraum grundsätzlich möglich, erfordert jedoch eine Ausgestaltung der Geldpolitik, die in qualitativer Hinsicht zeitkonsistent, aber in quantitativer Sicht zeitinkonsistent ist. Sie erfordert nämlich, dass die Zentralbank für den Zeitpunkt der antizipierten Ölpreiserhöhung eine Verringerung der Wachstumsrate der Geldmenge glaubwürdig ankündigt, letztendlich zum späteren Zeitpunkt der Ölpreiserhöhung eine etwas schwächere geldpolitische Reaktion implementiert.

  This paper uses a semi-structural dynamic modelling approach to investigate asymmetric monetary transmission in Europe. A system of equations containing reaction functions for monetary policy, output and inflation equations is simultaneously estimated for France, Germany, and Italy. Extensive cross equation tests show that relatively large differences in simulated impulse responses are still consistent with the notion that the transmission mechanism is homogeneous across the three major EMU countries. However, monetary policy impulses show a relatively stronger effect on the output gap in Italy and Germany. Out-of-sample tests do not find a structural break in the transmission mechanisms prior to EMU.

  This paper investigates in a consistent semi-structural empirical framework three current issues of monetary policy in the euro area. First, regarding policy transmission we offer a three-stage procedure to combine the efficient estimation of economic structure prior to EMU with current ECB monetary policy. Second, we test whether the regime change leads – before or after – EMU to structural instability. Third, we investigate the stance of monetary policy in Europe. We compare a "counterfactual" ECB reaction function based on average interest rates prior to EMU with actual ECB policy. Furthermore, we compare actual ECB policy with interest rate projections using Bundesbank reaction functions and euroland data.

  This paper investigates the dynamic effects of monetary and fiscal policy in a monetary union, which is characterized by asymmetric interest rate transmission. This asymmetry gives rise to intertemporal reversals in the relative effectiveness of policy on member country outputs. The direction and the number of these reversals depend on whether policies are unanticipated or anticipated. We also study the coordination between monetary and fiscal policy in a monetary union. Monetary policy may completely stabilize European output after unanticipated fiscal policy shocks. With anticipated fiscal policy shocks, complete stabilization throughout the overall adjustment process requires monetary policy to be time-inconsistent.

  This paper reviews the literature on asymmetric monetary transmission within the European Monetary Union (EMU). At first, a stylized model is presented in order to highlight the importance of asymmetric monetary transmission for the decision-making of the European Central Bank (ECB). The transmission mechanism is then decomposed into several subsequent stages. Various macroeconomic indicators for the EU countries related to financial, goods and labor markets are then used to assess the empirical relevance of asymmetries across the EU countries. Then, models of a monetary union are used to assess to which extent cross-country differences in individual channels of transmission translate into differences in the overall strength of monetary transmission in Europe. Finally, the paper assesses the extent to which the transmission patterns in Europe convergence as a result of the establishment of EMU. The paper finds the empirical evidence on cross-country differences in the policy impact to be inconclusive and provides suggestions for further theoretical and empirical research.

  The paper analyzes the dynamic effects of anticipated symmetric demand and supply side policies within the framework of a macroeconomic model of a small monetary union, which is characterized by asymmetric wage adjustment equations of Phillips‘ curve type. It is shown that an anticipated simultaneous increase in government expenditure in both member countries leads to a short-run fall in output and to temporary divergences in output developments. From the perspective of the country with the lower wage flexibility the output differential is positive in the short-run. In the course of the subsequent adjustment process the relative cyclical position is reversed. The difference between the two member country outputs changes its sign due to changes in the internal and external terms of trade. Similar results hold with a simultaneous reduction of labor extra-costs in both countries. Compared with a symmetric increase in government expenditure the development of the output differential is essentially opposite in sign.

  This paper analyzes the dynamic effects of monetary policy, fiscal policy, and foreign interest rate shocks in a monetary union, which is small relative to the rest of the world and simultaneously characterized by supply-side and demand-side asymmetries. We investigate both, the implications at the aggregate European level as well as in the individual member countries. The analysis distinguishes between anticipated and unanticipated shocks. We find that monetary policy, which is expansionary at the aggregate European level, may have a contractionary impact in individual member countries. Whereas monetary and fiscal policy cause temporary cyclical divergences within the monetary union, shocks to the world interest rate lead to lasting cyclical divergences within the monetary union.

  The European Central Bank uses a monetary strategy which represents a combination of monetary targeting and direct inflation targeting In this context, the stability of the long-run European money demand function is widely seen as a precondition for a strategy of monetary targeting. This paper investigates the aggregate demand for money in Europe including those countries representing the initial group in the European Monetary Union. First, we identify stable (in the sense of cointegrated) European money demand functions for M1 as well as for M3. Second, we investigate parameter constancy over time and do not find suggestive evidence of structural instability Overall, the results provide empirical support for the European Central Bank to target a European monetary aggregate.

  The European Central Bank will soon have to decide on her monetary strategy. This paper discusses properties of money demand functions and implications for monetary policy in a monetary targeting regime. Special attention is paid to different concepts of stability of money demand, to the length and variability of adjustment lags, and to the controllability of the money stock. At the European level, stable money demand functions are identified for M1 and M3. However, M3 appears to be less controllable than M1. Long and variable adjustment lags in the demand for M3 weaken the case for broad money as a monetary target.

  Three potential problems in the transition to European Monetary Union are analyzed in a three country model of a currency union. The problems discussed are the choice of a misaligned conversion rate at the time of the move to the currency union, the uncertainty with respect to the future stance of monetary policy of the European Central Bank and the risk of an asymmetric real wage push within the monetary union. The macroeconomic implications of these disturbances are analyzed and alternative strategies for monetary and fiscal policy are evaluated.

  The Bundesbank failed to achieve her monetary targets in numerous years. Against this background the present paper discusses the implications of these deviations for the exchange rate and the price level. The model by Dornbusch (1976) is augmented by an equation which captures the correction of the deviations in subsequent periods. In the case of single period deviations with immediately beginning correction the volatility of the exchange rate and the price level will be the smaller, the more decisively the money stock is driven back to the equilibrium level. In contrast, in the case of the multi-period deviations the volatility of the exchange rate will be the higher the faster the correction of the money stock.

  The paper analyzes the implications of fiscal consolidation efforts for the real external exchange rate. In the model following Dornbusch (1976) augmented by an equation reflecting the evolution of government spending, it is shown that the fluctuations of the real external exchange rate will be the smaller, the more decisively policy makers reduce public deficits. On the other hand, all other macroeconomic variables exhibit more short-term variability. In the decision about the speed of fiscal consolidation, policy makers face a short-term tradeoff between real exchange rate and other macroeconomic stability.

  The paper analyses the macroeconomic effects of monetary union in Germany (GMU) and tries to draw conclusions for European Monetary Union (EMU). For Germany, currency conversion led to a substantial appreciation in East Germany and contributed there to a decline in production and to heavy unemployment, necessitating high fiscal transfers. Interest rates rose, the DM-exchange rate appreciated and the capital account turned into a deficit position. On the other hand, it seems that money supply, money demand, and inflation have only been influenced in the short run. It can be shown that many of the problems experienced in Germany result from the joint and rapid introduction of the monetary, economic and social unification with a former socialist country. Therefore, if EMU is introduced as a separate affair costs and benefits will be relatively small, especially once wages are allowed to be flexible. The basic lesson from GMU for EMU is not to overloook the problems associated with a social union in Europe and not to underestimate the pressure towards wage equalisation in a monetary union.

  Gegenstand der Untersuchung ist die theoretische und empirische Analyse der Bedeutung der Geld- und Fiskalpolitik für die Wechselkursentwicklung. Als Referenzsystem wird dabei das Modell von Dornbusch (1976) zugrundegelegt. Mittels einer theoretischen Sensitivitätsanalyse wird zunächst für geldpolitische Impulse geprüft, inwieweit die Hypothese überschießender Wechselkursreaktionen (Overshooting) auch in verallgemeinerten Modellstrukturen Gültigkeit besitzt. Im nächsten Schritt wird die Frage gestellt, unter welchen Umständen auch durch fiskalpolitische Impulse überschießende Wechselkursreaktionen ausgelöst werden. In der empirischen Analyse wird sowohl der kurz- als auch der langfristige Einfluß der Geld- und Fiskalpolitik auf die Entwicklung des DM/Dollar-Wechselkurses geschätzt.

  This paper demonstrates on the basis of a modified (Dornbusch 1976) model with real income levels determined by short-term demand and with a nominal monetary demand level dependent upon the consumer price index that substantial exchange rate fluctuations may be caused by fiscal impulses in both the long and the short terms. Exchange-rate-overshooting in the short term occurs whenever the interest rate response is normal, i. e. when the level of domestic interest rises after a period of expansionary fiscal policy. It is shown that the longterm exchange rate effects of an expansionary fiscal policy course depend strongly on the respective combination of structural parameters. These effects have hitherto been neglected in the analyses made, which focused exclusively on the short-term fluctuations around an equilibrium value not yet examined in detail. It is also demonstrated that there may be a tradeoff between the short-term and the long-term exchange-rate varialility under certain circumstances.
