A German broker’s clients place similar speculative trades and therefore tend to be on the same side of the market in a given stock during a given day, week, month, and quarter. Aggregate liquidity effects, short sale constraints, the systematic execution of limit orders (coordinated through...

This paper analyses the determinants of international asset portfolios, using a neoclassical dynamic general equilibrium model with home bias in consumption. For plausible parameter values, the model explains the fact that typical investors hold most of their wealth in domestic assets (portfolio...

Our objective is to understand the trading strategy that would allow an investor to take advantage of 'excessive' stock price volatility and 'sentiment' fluctuations. We construct a general equilibrium model of sentiment. In it, there are two classes of agents and stock prices are excessively...

The paper presents a two-country macroeconomic model in which the number of financial assets is endogenous. Imperfect substitutability of assets and international transaction costs give a comparative advantage to large markets, because of demand effects. Agents have more incentives to undertake...

We examine the view that the recent East Asian crisis was precipitated by bursting asset price bubbles which had been fuelled by strong capital inflows which were largely the result of a moral hazard problem in financial intermediation, and was exacerbated by a vicious cycle of asset price...

We introduce a form of pre-play communication that we call "preopening". During the preopening, players announce their tentative actions to be played in the underlying game. Announcements are made using a posting system which is subject to stochastic failures. Posted actions are publicly...

In der wirtschaftswissenschaftlichen Literatur wird das ökonomische Potenzial von Immobilienverzehrprodukten vielseitig diskutiert. Obwohl diesen Produkten aus wohlfahrts-theoretischen Gesichtspunkten eine hohe Bedeutung beigemessen wird, zeigt die empirische Evidenz, dass die Nachfrage weit...

We join the new trade theory with a model of choice between bank and bond financing to show the differential effects of financial policy on the distribution of firm size, welfare, aggregate output, gains from trade, and the real exchange rate in a small open economy. Increasing bank efficiency...

Fünf Jahre nach der Abschaffung der umfassenden Haftung für Landesbanken hat sich deren Lage deutlich verschärft. Dazu hat auch die internationale Finanzkrise beigetragen. Einzelne Landesbanken benötigten erhebliche Kapitalspritzen. Inzwischen ist klar, dass eine weitere Konsolidierung im...

We use high-frequency data to study the dynamic relationship between volatility and equity returns. We provide evidence on two alternative mechanisms of interaction between returns and volatilities: the leverage effect and the volatility feedback effect. The leverage hypothesis asserts that...
