We identify local and global factors across international bond markets that are poorly spanned by the cross-section of yields but have strong forecasting power for future bond excess returns. Local and global factors are jointly signicant predictors of bond returns, where the global factor is closely linked to US bond risk premia and international business cycles. Motivated by our...

Multiplicity of equilibria is a prevalent problem in many economic models. Often equilibria are characterized as solutions to a system of polynomial equations. This paper gives an introduction to the application of GrÄobner basis methods for ¯nding all solutions of a polynomial system. The Shape Lemma, a key result from algebraic geometry, states under mild assumptions that a given...

This article suggests a reform of the organisation of money markets that would largely eliminate the risk
of contagion. The notion of “systemically important institution” would be replaced by that of systemically
important platform”. Such platforms would only be directly accessible to a group of “offi cially recognised
fi nancial institutions” that would have to...

We analyze the attractiveness of investment strategies over a variety of investment horizons from the viewpoint of an investor with preferences described by Cumulative Prospect Theory (CPT), currently the most prominent descriptive theory for decision making under uncertainty. A bootstrap technique is applied using historical return data of 1926–2008. To allow for variety in...

We build a general model for pricing defaultable claims. In addition to the usual absence of arbitrage assumption, we assume that one defaultable asset (at least) looses value when the default occurs. We prove that under this assumption, in some standard market filtrations, default times are totally inaccessible stopping times; we therefore proceed to a systematic construction of...

In this paper we present a recursive method for the computation of dynamic competitive equilibria in models with heterogeneous agents and market frictions. This method is based on a convergent operator over an expanded set of state variables. The fixed point of this operator defines the set of all Markovian equilibria. We study approximation properties of the operator as well as the...
