Published / Preprint: Quantifying the influence of scientists and their publications: distinguishing between prestige and popularity

Posted: 31 May 2012 03:15 AM PDT

The number of citations is a widely used metric for evaluating the scientific credit of papers, scientists and journals. However, it so happens that papers with fewer citations from prestigious scientists have a higher influence than papers with more citations. In this paper, we argue that by whom the paper is being cited is of greater significance than merely the number of citations....

Published / Preprint: Cascade Failure in a Phase Model of Power Grids

Posted: 31 May 2012 01:53 AM PDT

We propose a phase model to study cascade failure in power grids composed of generators and loads. If the power demand is below a critical value, the model system of power grids maintains the standard frequency by feedback control. On the other hand, if the power demand exceeds the critical value, an electric failure occurs via step out (loss of synchronization) or voltage col 563 lapse. The two...

Published / Preprint: Agent-based simulations of emotion spreading in online social networks

Posted: 31 May 2012 12:30 AM PDT

Quantitative analysis of empirical data from online social networks reveals group dynamics in which emotions are involved (\v{S}uvakov et al). Full understanding of the underlying mechanisms, however, remains a challenging task. Using agent-based computer simulations, in this paper we study dynamics of emotional communications in online social networks. The rules that guide how the agents...

I wanted to share a couple of great segments from Al Jazeera's 101 East: both of these recent segments contain several examples of innovations that would translate in many other countries. Aravind Eye Care in Madurai has been the subject of numerous business school case studies, but if you want an introduction to this amazing organization, the video below is a great place to start.

Blog Post: Falkenblog: Experience is an Imperfect Teacher

Posted: 30 May 2012 07:03 PM PDT

It has been said that good judgement comes from experience, and experience comes from bad judgment.  Unfortunately, one doesn't always learn good judgment from experience.  From Russ Roberts' interview with Lawrence White over at EconTalk:Lawrence White: I think the idea you referred to earlier of Friedman's, that people have to learn from experience that a certain program of control...

Published / Preprint: Collateralized CVA Valuation with Rating Triggers and Credit Migrations. (arXiv:1205.6542v1 [q-fin.PR])

Posted: 30 May 2012 05:30 PM PDT

In this paper we discuss the issue of computation of the bilateral credit valuation adjustment (CVA) under rating triggers, and in presence of ratings-linked margin agreements. Specifically, we consider collateralized OTC contracts, that are subject to rating triggers, between two parties -- an investor and a counterparty. Moreover, we model the margin process as a functional of the credit...

Research Library: Bank of England Financial Stability Paper: The implicit subsidy of banks

Posted: 30 May 2012 06:52 AM PDT

Joseph Noss and Rhiannon Sowerbutts This paper examines the implicit subsidy of UK banks by the government and the associated distortions in the financial system. It explains why the subsidy arises, why it is a public policy concern and explores how it can be quantified. Quantifying the implicit subsidy to banks has generated considerable interest over recent years. The numbers are striking,...

Published / Preprint: Efficient greek estimation in generic swap-rate market models

Posted: 30 May 2012 05:37 AM PDT

We first develop an efficient algorithm to compute Deltas of interest rate derivatives for a number of standard market models. The computational complexity of the algorithms is shown to be proportional to the number of rates times the number of factors per step. We then show how to extend the method to efficiently compute Vegas in those market models.read more...

Published / Preprint: Forecasting prices from level-I quotes in the presence of hidden liquidity

Posted: 30 May 2012 05:37 AM PDT

Bid and ask sizes at the top of the order book provide information on short-term price moves. Drawing from classical descriptions of the order book in terms of queues and order-arrival rates (Smith et al., 2003), we consider a diffusion model for the evolution of the best bid/ask queues. We compute the probability that the next price move is upward, conditional on the best bid/ask sizes, the...

Published / Preprint: Behavioral biases and investor performance

Posted: 30 May 2012 05:37 AM PDT

Research indicates that individual investors trade excessively and underperform the market indices, Barber and Odean (2000). The purpose of this paper is to help explain which behavioral biases, if any, can explain this result using a simulation approach. Results indicate that putting too much weight on the current environment, anchoring, is the largest factor in explaining individual investor...

Published / Preprint: Markets are efficient if and only if P = NP

Posted: 30 May 2012 05:37 AM PDT

I prove that if markets are efficient, meaning current prices fully reflect all information available in past prices, then P = NP, meaning every computational problem whose solution can be verified in polynomial time can also be solved in polynomial time. I also prove the converse by showing how we can “program” the market to solve NP-complete problems. Since P probably does not equal NP,...

Published / Preprint: Binomial options pricing has no closed-form solution

Posted: 30 May 2012 05:37 AM PDT

We set a lower bound on the complexity of options pricing formulae in the lattice metric by proving that no general explicit or closed form (hypergeometric) expression for pricing vanilla European call and put options exists when employing the binomial lattice approach. Our proof follows from Gosper's algorithm.read more...

Posted: 30 May 2012 05:37 AM PDT

Delineating industry groups of related firms and identifying strategic peers is important for both financial practitioners and scholars. Our study explores whether the degree to which pairs of companies are associated with each other in an online stock forum is related to the comovement of their stocks. We find that our news-based measure of relatedness can explain stock returns with the same...
