It is common practice to describe the future evolution of a financial profit by a continuous-time stochastic model. A risk measure can then be viewed as a functional on a space of continuous-time stochastic processes. We extend the notions of coherent and convex risk measures to the space of...

The correlation between returns on US stocks and Treasury bonds has varied sub-stantially over time. From being highly positive in the 1970's and 1980's, correlationsturned sharply negative in the early 2000's, and were particularly low during the recentnancial crisis. Concurrent with the...

We identify local and global factors across international bond markets that arepoorly spanned by the traditional level, slope and curvature factors but havestrong forecasting power for future bond excess returns. Local and global fac-tors are jointly signicant predictors of bond returns, where...

This paper examines the investment strategies of regulated companies in abatement technologies,market participants' trading behaviors, and the liquidity level in an inter-temporalcap{and{trade market using laboratory experiments. The experimental analysis is performedunder varying market...

This paper summarizes the short selling restrictions adopted—mainly on anemergency basis—in the time period of July 2008 up to mid-June 2010 in 56countries around the world. It is a supplement to a recent article of theauthors (Gruenewald et al., 2010) and gives a detailed overview of...

On financial markets many investment decisions are taken by groups and not by individuals. The evidence, however, whether groups better than individuals, is ambigous. We analyze the portfolios of groups and individuals in an asset allocation task on an experimental market. We find that groups on...

We introduce and study no-good-deal valuation bounds defined in terms of expected utility. A utility-based good deal is a payoff whose expected utility is toohigh in comparison to the utility of its price. Forbidding good deals induces, viaduality, restrictions on pricing kernels and thereby...

We study the exponential utility indifference valuation of a contingent claim B in an incomplete market driven by two Brownian motions. The claim depends on a nontradable asset stochastically correlated with the traded asset available for hedging. We use martingale arguments to provide upper and...

It is well known that the class of strong (Generalized) AutoRegressive Conditional Heteroskedasticity (or GARCH) processes is not closed under contemporaneous aggregation. This paper provides the dynamics followed by the aggregate process when the individual persistence parameters are drawn from...

In the recent work of Dempster, Evstigneev and Taksar (2006) it has been shown that the von Neumann-Gale model of economic dynamics can serve as a convenient and natural framework for the analysis of questions of asset pricing and hedging under transaction costs. The present article focuses on a...
