Published / Preprint: Transformation Method for Solving Hamilton-Jacobi-Bellman Equation for Constrained Dynamic Stochastic Optimal Allocation Problem. (arXiv:1307.3672v1 [q-fin.PM])

Posted: 15 Jul 2013 05:37 PM PDT

In this paper we propose and analyze a method based on the Riccati transformation for solving the evolutionary Hamilton-Jacobi-Bellman equation arising from the stochastic dynamic optimal allocation problem. We show how the fully nonlinear Hamilton-Jacobi-Bellman equation can be transformed into a quasi-linear parabolic equation whose diffusion function is obtained as the value function of...

Published / Preprint: Heavy tailed time series with extremal independence. (arXiv:1307.1501v1 [math.ST] CROSS LISTED)

Posted: 15 Jul 2013 05:37 PM PDT

We consider strictly stationary heavy tailed time series whose finite-dimensional exponent measures are concentrated on axes, and hence their extremal properties cannot be tackled using classical multivariate regular variation that is suitable for time series with extremal dependence. We recover relevant information about limiting behavior of time series with extremal independence by introducing...

Blog Post: Falkenblog: Beware Discrete Auctions

Posted: 15 Jul 2013 06:41 AM PDT

There's an interesting paper on High Frequency Trading (HFT) by Budish, Cramton, and Shim from the U of Chicago. They set up an interesting model, but then propose at the end that batching eliminates the HFT arms race, both because it reduces the value of tiny speed advantages and because it transforms competition on speed into competition on price. I think that solution is interesting, but...
