متن کاملCan Capacity Constraint Explain Introduction of New Hedge Funds?
In this paper we test the idea that hedge funds‟ capacity constraints may play a significant role on the decision of fund families to open a new hedge fund. Our empirical analysis shows that fund families‟ propensity to open new funds increases with degree of capacity constraint faced by existing funds of the families. We argue that hedge fund families face diseconomies of scale because of the ...

Although risk management has been a well-plowed field in financial modeling for more than two decades, traditional risk management tools such as mean–variance analysis, beta, and Value-at-Risk do not capture many of the risk exposures of hedge-fund investments. In this article, I review several unique aspects of risk management for hedge funds—survivorship bias, dynamic risk analytics, liquidit...
متن کاملClosure of Hedge-automata Languages by Hedge Rewriting Closure of Hedge-automata Languages by Hedge Rewriting
We consider rewriting systems for unranked ordered terms, i.e. trees where the number of successors of a node is not determined by its label, and is not a priori bounded. The rewriting systems are defined such that variables in the rewrite rules can be substituted by hedges (sequences of terms) instead of just terms. Consequently, this notion of rewriting subsumes both standard term rewriting a...
متن کاملAdaptive Hedge
Most methods for decision-theoretic online learning are based on the Hedge algorithm, which takes a parameter called the learning rate. In most previous analyses the learning rate was carefully tuned to obtain optimal worst-case performance, leading to suboptimal performance on easy instances, for example when there exists an action that is significantly better than all others. We propose a new...
