The article illustrates how the integration of modern theory of finance and stochastic dynamic macroeconomic analysis provides a deeper understanding of the link between asset prices and consumption. It shows that this approach gives only a partial explanation for recent trends in US consumption. Comparing wealth effects in Anglo Saxon countries with continental Europe, the paper provides a perspective of the challenges for European monetary policy arising from wealth effects on consumption.

This paper provides a unified theory to explain the onset of the financial crisis in 1998 and the striking economic recovery in Russia and the former Soviet Union afterwards. Before the crisis, the banking sector in these economies was stuck in a development trap in which the banking sector is separated from the real sector of the economy. The separation between the two sectors arises due to a lemons lending market and due to a large government budget. In a lemons credit market firms may find it cheaper to raise liquidity through non-bank finance (trade credits from other firms) rather than through bank finance. As a result non-bank finance may generate an externality on the lending rates of banks. In equilibrium most firms in the economy rely on non-bank finance and the financial sector focuses on trading government securities. The collapse of the treasury bills market in Russia in the financial crisis of 1998 reversed this process and thus acted as a trigger to pull the economy out of the trap. This has led to the strong economic recovery and provided initial conditions for banking development. Empirical evidence with firm level data from Ukraine in 1997 and with country level data for transition economies support the model’s predictions.

We explore the efficiency of the forward reichsmark market in Vienna between 1876 and 1914. We estimate ARIMA models of the spot exchange rate in order to forecast the one-month-ahead spot rate. In turn we compare these forecasts to the contemporaneous forward rate, i.e., the market's forecast of the future spot rate. We find that shortly after the introduction of a "shadow" gold standard in the mid-1890s the forward rate became a considerably better predictor of the future spot rate than during the prior flexible exchange rate regime. Between 1907 and 1914 forecast errors were between a half and one-fourth of their pre-1896 level. This implies that the Austro-Hungarian Bank's policy of defending the gold value of the currency was successful in improving the efficiency of the foreign exchange market.

Daily data from the German and U.S. equity markets before and after the introduction of the Euro are used to study the effect of exchange rate regime choices on equity markets. It is found that, since the introduction of the Euro, the volatility and the persistence of the German stock index have fallen significantly relative to those of the U.S. index. However, the switch in exchange rate arrangement appears to have no significant implication for the causal relationships - both the mean and varianc causalities - between the two equity markets.

Der Aufsatz gibt zunächst einen kurzen Überblick über die Entwicklung des Marktes für Wagniskapital in den USA und in Deutschland. Dann wird gezeigt, mit welchen besonderen Anreiz- und Vertragsproblemen die Finanzierung von Innovationen zu kämpfen hat und welche neuen Instrumente von der Wagniskapitalbranche in den letzten Jahrzehnten entwickelt wurden, um diese Probleme in den Griff zu bekommen. Schließlich diskutieren wir die wichtigsten Argumente für die staatliche Subventionierung von Innovationen und zeigen, in welcher Form die Förderung der Wagniskapitalfinanzierung möglichst effizient erfolgen sollte.

In the course of the EU enlargement process, the participation of accession countries in the European Monetary Union might lead to a significant redistribution of seigniorage wealth if current regulations prevail. In general, accession countries will be winners from this redistribution, for example Poland with 12.9 billion euros, Romania with 9.9 billion euros or Hungary with 3.3 billion euros. Correspondingly, the current member countries of the European Union face costs of 35.3 billion euros in total, the biggest part of which has to be borne by Germany.

Many practitioners point out that the speculative profits of institutional traders arc eroded by the difficulty in gauging the price impact of their trades. In this paper. we develop a model of strategic trading where speculators face such a dilemma because of incomplete information about time-varying market liquidity. Unlike the competitive market makers that they trade against, informed traders do not know whether the liquidity ( "noise") trades are generated from a distribution with high or low variance. Instead, they have to learn about liquidity from past prices and trading volume. Extreme price deviations from forecasts of fundamentaIs based on public news or low trading volume tend to lead to revisions of beliefs in favor of the low liquidity state. This revision in beliefs implies that strategie trades and market statistics such as informational efficiency arc path-dependent on past market outcomes. Our paper has a number of normative implications for practitioners concerned with gauging the potential price impact of their trades.
