Published / Preprint: Why Mass Media Matter to Planning Research: The Case of Megaprojects. (arXiv:1304.1665v1 [q-fin.GN])

Posted: 07 Apr 2013 05:30 PM PDT

This article asks how planning scholarship may effectively gain impact in planning practice through media exposure. In liberal democracies the public sphere is dominated by mass media. Therefore, working with such media is a prerequisite for effective public impact of planning research. Using the example of megaproject planning, it is illustrated how so-called "phronetic planning research," which...

Published / Preprint: A convolution method for numerical solution of backward stochastic differential equations. (arXiv:1304.1783v1 [math.PR])

Posted: 07 Apr 2013 05:30 PM PDT

We propose a new method for the numerical solution of backward stochastic differential equations (BSDEs) which finds its roots in Fourier analysis. The method consists of an Euler time discretization of the BSDE with certain conditional expectations expressed in terms of Fourier transforms and computed using the fast Fourier transform (FFT). The problem of error control is addressed, we consider...

Published / Preprint: Stochastic Utilities With a Given Optimal Portfolio : Approach by Stochastic Flows. (arXiv:1004.5192v2 [q-fin.CP] UPDATED)

Posted: 07 Apr 2013 05:30 PM PDT

The paper generalizes the construction by stochastic flows of consistent utility processes introduced by M. Mrad and N. El Karoui in (2010). The utilities random fields are defined from a general class of processes denoted by $\GX$. Making minimal assumptions and convex constraints on test-processes, we construct by composing two stochastic flows of homeomorphisms, all the consistent...

Blog Post: ThePracticalQuant: The re-emergence of Time-series

Posted: 07 Apr 2013 12:06 PM PDT

[A version of this post appeared on the O'Reilly Strata blog.]My first job after leaving academia was as a quant1 for a hedge fund, where I performed (what are now referred to as) data science tasks on financial time-series. I primarily used techniques from probability & statistics, econometrics, and optimization, with occasional forays into machine-learning (clustering, classification,...
