Blog Post: Falkenblog: Blaming the Victim

Posted: 29 Oct 2012 07:12 PM PDT

Every week brings a new billion dollar settlement against the banks that supposedly rammed this stuff down the throats of the noble savages who couldn't afford the homes they bought.  Luigi Zingales notes a study on how culpable banks were:Predatory lending is commonly defined as lending that imposes unfair and abusive loan terms on borrowers. The immediate effect of this mandatory...

Published / Preprint: Uniqueness of Kusuoka Representations. (arXiv:1210.7257v1 [math.ST])

Posted: 29 Oct 2012 05:46 PM PDT

This paper addresses law invariant coherent risk measures and their Kusuoka representations. By elaborating the existence of a minimal representation we show that every Kusuoka representation can be reduced to its minimal representation. Uniqueness -- in a sense specified in the paper -- of the risk measure's Kusuoka representation is derived from this initial result. read more...

Published / Preprint: The Zeeman Effect in Finance: Libor Spectroscopy and Basis Risk Management. (arXiv:1210.7329v1 [q-fin.PR])

Posted: 29 Oct 2012 05:45 PM PDT

Once upon a time there was a classical financial world in which all the Libors were equal. Standard textbooks taught that simple relations held, such that, for example, a 6 months Libor Deposit was replicable with a 3 months Libor Deposits plus a 3x6 months Forward Rate Agreement (FRA), and that Libor was a good proxy of the risk free rate required as basic building block of no-arbitrage pricing...

Published / Preprint: Isobenefit Lines, Breaking Point of equal attraction, Uniformity Benefit, Variety Value and Proximity Value, Preference Gap Gain. (arXiv:1210.7510v1 [q-fin.GN])

Posted: 29 Oct 2012 05:45 PM PDT

Isobenefit Lines can offer a certain range of applicability in Location Theory and Gravitational Models for Urban and Geography Economics, in positional decision processes made by citizens, and, last but not least, in land value and property market theories and analysis. The value of a land, or a property, in a generic k point, is, ceteris paribus, the mirror of the quality, attractiveness,...

Published / Preprint: Execution and block trade pricing with optimal constant rate of participation. (arXiv:1210.7608v1 [q-fin.TR])

Posted: 29 Oct 2012 05:45 PM PDT

In this article, we develop a liquidation model in which the trader is constrained to liquidate a portfolio at constant participation rate. Considering the functional forms usually used by practitioners, we obtain a closed-form expression for the optimal participation rate and for the liquidity premium a trader should quote to buy a large block of shares. We also show that the difference in terms...

Published / Preprint: Estimation of the shape parameter of a generalized Pareto distribution based on a transformation to Pareto distributed variables. (arXiv:1210.7642v1 [q-fin.CP])

Posted: 29 Oct 2012 05:45 PM PDT

Random variables of the generalized Pareto distribution, can be transformed to that of the Pareto distribution. Explicit expressions exist for the maximum likelihood estimators of the parameters of the Pareto distribution. The performance of the estimation of the shape parameter of generalized Pareto distributed using transformed observations, based on the probability weighted method is tested....

Published / Preprint: Halton-type sequences from global function fields. (arXiv:1210.7721v1 [math.NT])

Posted: 29 Oct 2012 05:45 PM PDT

For any prime power $q$ and any dimension $s$, a new construction of $(t,s)$-sequences in base $q$ using global function fields is presented. The construction yields an analog of Halton sequences for global function fields. It is the first general construction of $(t,s)$-sequences that is not based on the digital method. The construction can also be put into the framework of the theory of...

Alan Kirman - What's the use of Economics?

Posted: 29 Oct 2012 09:38 AM PDT

The economic crisis has thrown the inadequacies of macroeconomics into stark relief. The narrow conception of the macroeconomy as a system in equilibrium is problematic. Economists should abandon entrenched theories and understand the macroeconomy as self-organising. This column offers detailed suggestions on what alternative ideas economists can teach their future students that better reflect...
