We develop a new theory of international capital flows based on dispersed in-formation across individual investors. There is extensive evidence of informationheterogeneity within and across countries, which has proven critical to under-standing asset price behavior. We introduce information...

This paper studies the asset pricing implications of a general equi-librium model in which real investment is reversible at a cost. Firmsface higher costs in contracting than in expanding their capital stockand decide to invest when their productive capital is scarce relativeto the overall...

Filtrations have been introduced by Doob and have been a fundamentalfeature of the theory of stochastic processes. Most basic objects, such asmartingales, semimartingales, stopping times or Markov processes involvethe notion of filtration.[...]

Two experiments investigated impacts of hazard types and information deliveries on riskperception, with a focus on the role of emotions. In the first experiment, technologicalhazards aroused stronger emotions, and were considered as riskier than natural hazards. Nodifferences were found between...

We study a quadratic BSDE in a continuous filtration with an unbounded generatorand an infinite time horizon. This equation comes from a stochasticcontrol problem in the context of robust utility maximisation.[...]

We study the robustness of block resampling procedures for time series. We first derive a setof formulas to quantify their quantile breakdown point. For the block bootstrap and the sub-sampling, we find a very low quantile breakdown point. A similar robustness problem arisesin relation to...

This chapter gives an overview of current research in evolutionary -nance. We mainly focus on the survival and stability properties ofinvestment strategies associated with the Kelly rule. Our approach tothe study of the wealth dynamics of investment strategies is inspired byDarwinian ideas on...

In the presence of transactions costs, no matter how small, ar-bitrage activity does not necessarily render equal all riskless rates ofreturn. When two such rates follow stochastic processes, it is not opti-mal immediately to arbitrage out any discrepancy that arises betweenthem. The reason is...

Despite the enormous growth of the asset management industry during the pastdecades, little is known so far about the asset pricing implications of investmentintermediaries. Investment objectives of professional asset managers such as mutualfunds differ from those of private households. However,...

Consider an Rd-valued semimartingale S and a sequence of Rd-valuedS-integrable predictable processes Hn valued in some closed convex set K C Rd,containing the origin. Suppose that the real-valued sequence Hn * S converges toX in the semimartingale topology.[...]
