Blog Post: TheAlephBlog: How Warren Buffett is Different from Most Investors, Part 2

Posted: 04 Sep 2012 09:31 PM PDT

Before I begin this evening, let me simply say that where I find intelligence, I appreciate it, whether I agree with all the ethics of the situation or not.  Buffett is a bright guy, brighter than most.  I have *not* been shy to criticize Buffett when I thought there were ethical lapses — whether it was retroactive reinsurance, life settlements, David Sokol, or anything else.read more...

Blog Post: Falkenblog: Economists Love The Spread

Posted: 04 Sep 2012 06:07 PM PDT

The spread is a debating tactic where you present a set of supporting arguments so wide and particular your opponents are unable to rebut them all because 1) they have day jobs and 2) they have limited space or time to address them in any particular forum.  A champion spreader is Noam Chomsky, who selectively recites facts of world history from Indonesia, Russia, to El Salvadore and 200...

Published / Preprint: Crises and collective socio-economic phenomena: cartoon models and challenges. (arXiv:1209.0453v1 [cond-mat.stat-mech])

Posted: 04 Sep 2012 05:30 PM PDT

Financial and economic history is strewn with bubbles and crashes, booms and busts, crises and upheavals of all sorts. Understanding the origin of these events is arguably one of the most important problems in economic theory. In this paper, we review recent efforts to include heterogeneities and interactions in models of decision. We argue that the Random Field Ising model (RFIM) indeed provides...

Published / Preprint: Pricing of Variance Swaps under a Credit-Equity Modeling Framework. (arXiv:1209.0697v1 [q-fin.PR])

Posted: 04 Sep 2012 05:30 PM PDT

We compute the value of a variance swap when the underlying is modeled as a Markov process time changed by a L\'{e}vy subordinator. In this framework, the underlying may exhibit jumps with a state-dependent L\'{e}vy measure, local stochastic volatility and have a local stochastic default intensity. Moreover, the L\'{e}vy subordinator that drives the underlying can be obtained...

A model is presented in this work for simulating endogenously the evolution of the marginal costs of production of energy carriers from non-renewable resources, their consumption, depletion pathways and timescales. Such marginal costs can be used to simulate the price formation of energy commodities. Drawing on previous work where a global database of energy resource economic potential was...

An essay on the meandering path of the word "quant"

Posted: 04 Sep 2012 08:08 AM PDT

Aaron Brown posts an in depth and useful dissection of the word 'Quant', analysing it's usage and implications. As he says, "Sloppy use can lead to error. For example, are the quants in Scott Patterson’s book The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It as wise and gentle as Emanuel Derman? Or are the words being used in different senses?"read...

We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how illiquidity affects expected asset returns. Using a unified model from...
