Germany and the European Business Cycle - An Analysis of Causal Relations in an International Real Business Cycle Model

This paper studies the role of the German economy for the existence of the so called European business cycle, a term referring to the regularly observed synchronization of the national business cycles in Europe. Using a three-country general equilibrium model, we are able to simulate impulse response functions mimicking the important features observed in the data. Focusing on the importance of shocks affecting the German GDP we show that trade-related transmission from Germany to the other European economies is only of minor importance for the synchronization of national business cycles. On the contrary, our findings suggest that the influence of common shocks and of technology spillovers accounts for most of the parallels in economic performance.European business cycle; Transmission; Open economy macroeconomics; Real business cycles

Leading indicators in a globalised world

Using OECD composite leading indicators (CLI), we assess empirically whether the ability of the country- specific CLIs to predict economic activity has diminished in recent years, e.g. due to rapid advances in globalisation. Overall, we find evidence that the CLI encompasses useful information for forecasting industrial production, particularly over horizons of four to eight months ahead. The evidence is particularly strong when taking cointegration relationships into account. At the same time, we find indications that the forecast accuracy has declined over time for several countries. Augmenting the country-specific CLI with a leading indicator of the external environment and employing forecast combination techniques improves the forecast performance for several economies. Over time, the increasing importance of international dependencies is documented by relative performance gains of the extended model for selected countries.

The Future of the International Monetary System

The financial crisis of 2007/2008 and the current "Euro crisis" challenge the current global monetary system. They drastically reveal the actual system's weaknesses und show the eminent importance of the international monetary system for the stability of markets and national economies. DIW Berlin was commissioned by the Federal Ministry of Finance to research possible alternatives to the existing exchange rate regime. In principle, neither of the two extremes - completely free or fixed exchange rates - is suitable. A mixed system is preferable - with improvements to the status quo, though. An exchange rate regime with few big currency areas, which are linked to each other with flexible exchange rates, should be the aim of reforms. This should correspond to a multi-polar key currency system with the currently dominating US Dollar and the Euro as well as the Chinese Renmimbi as most important actors. These developments should be accompanied by substantial improvements in the regulatory framework of the financial markets. Necessary elements are a reinforced global and especially European economic coordination and an internationally agreed-on, assertive financial market authority.International Monetary System, Key Currency, Exchange Rate System, Financial Crisis, International Economic Policy
