Published / Preprint: Kinetic models of immediate exchange. (arXiv:1505.01274v1 [q-fin.GN])

Posted: 06 May 2015 05:37 PM PDT

We propose a novel kinetic exchange model differing from previous ones in two main aspects. First, the basic dynamics is modified in order to represent economies where immediate wealth exchanges are carried out, instead of reshufflings or uni-directional movements of wealth. Such dynamics produces wealth distributions that describe more faithfully real data at small values of wealth. Secondly, a...

Published / Preprint: A robust and efficient estimator of Sharpe ratios based on price records. (arXiv:1505.01333v1 [q-fin.ST])

Posted: 06 May 2015 05:37 PM PDT

Sharpe ratios are much used in finance, yet cannot be measured directly because price returns are non-Gaussian. On the other hand, the number of records of a discrete-time random walk in a given time-interval follows a Gaussian distribution provided that its increment distribution has finite variance. As as consequence, record statistics of uncorrelated, biased, random walks provide an attractive...

Published / Preprint: Inference on the Sharpe ratio via the upsilon distribution. (arXiv:1505.00829v1 [q-fin.PM])

Posted: 05 May 2015 05:37 PM PDT

The upsilon distribution, the sum of independent chi random variates and a normal, is introduced. As a special case, the upsilon distribution includes Lecoutre's lambda-prime distribution. The upsilon distribution finds application in Frequentist inference on the Sharpe ratio, including hypothesis tests on independent samples, confidence intervals, and prediction intervals, as well as their...

Published / Preprint: An Introduction to Multilevel Monte Carlo for Option Valuation. (arXiv:1505.00965v1 [math.NA])

Posted: 05 May 2015 05:37 PM PDT

Monte Carlo is a simple and flexible tool that is widely used in computational finance. In this context, it is common for the quantity of interest to be the expected value of a random variable defined via a stochastic differential equation. In 2008, Giles proposed a remarkable improvement to the approach of discretizing with a numerical method and applying standard Monte Carlo. His multilevel...

Published / Preprint: Non-Arbitrage Under Additional Information for Thin Semimartingale Models. (arXiv:1505.00997v1 [q-fin.MF])

Posted: 05 May 2015 05:37 PM PDT

This paper completes the two studies undertaken in \cite{aksamit/choulli/deng/jeanblanc2} and \cite{aksamit/choulli/deng/jeanblanc3}, where the authors quantify the impact of a random time on the No-Unbounded-Risk-with-Bounded-Profit concept (called NUPBR hereafter) when the stock price processes are quasi-left-continuous (do not jump on predictable stopping times). Herein, we focus on...

Published / Preprint: Picking Winners? Investment Consultants' Recommendations of Fund Managers

Posted: 05 May 2015 12:58 AM PDT

Investment consultants advise institutional investors on their choice of fund manager. Focusing on U.S. actively managed equity funds, we analyze the factors that drive consultants̢۪ recommendations, what impact these recommendations have on flows, and how well the recommended funds perform. We find that investment consultants̢۪ recommendations of funds are driven largely by soft factors,...

Published / Preprint: Profitability of contrarian strategies in the Chinese stock market. (arXiv:1505.00328v1 [q-fin.TR])

Posted: 04 May 2015 05:38 PM PDT

This paper reexamines the profitability of loser, winner and contrarian portfolios in the Chinese stock market using monthly data of all stocks traded on the Shanghai Stock Exchange and Shenzhen Stock Exchange covering the period from January 1997 to December 2012. We find evidence of short-term and long-term contrarian profitability in the whole sample period when the estimation and holding...

Posted: 04 May 2015 05:38 PM PDT

The present paper analyses the formal parallelism existing between the laws of thermodynamics and some economic principles. Based on previous works, we shall show how the existence in Economics of principles analogous to those in thermodynamics involves the occurrence of economic events that remind of well-known phenomenological thermodynamic paradigms (i.e., the magnetocaloric effect and...

Published / Preprint: A general Doob-Meyer-Mertens decomposition for $g$-supermartingale systems. (arXiv:1505.00597v1 [math.PR])

Posted: 04 May 2015 05:38 PM PDT

We provide a general Doob-Meyer decomposition for $g$-supermartingale systems, which does not require any right-continuity on the system. In particular, it generalizes the Doob-Meyer decomposition of Mertens (1972) for classical supermartingales, as well as Peng's (1999) version for right-continuous $g$-supermartingales. As examples of application, we prove an optional decomposition theorem for...

Published / Preprint: On statistical indistinguishability of complete and incomplete discrete time market models. (arXiv:1505.00638v1 [q-fin.MF])

Posted: 04 May 2015 05:38 PM PDT

We investigate the possibility of statistical evaluation of the market completeness for discrete time stock market models. It is known that the market completeness is not a robust property: small random deviations of the coefficients convert a complete market model into a incomplete one. The paper shows that market incompleteness is also non-robust. We show that, for any incomplete market from a...

Recent years have seen an unprecedented rise of the role that technology plays in all aspects of human activities. Unavoidably, technology has heavily entered the Capital Markets trading space, to the extent that all major exchanges are now trading exclusively using electronic platforms. The ultra fast speed of information processing, order placement, and cancelling generates new dynamics which...

Published / Preprint: Continuous-time trading and the emergence of probability. (arXiv:0904.4364v4 [math.PR] UPDATED)

Posted: 04 May 2015 05:37 PM PDT

This paper establishes a non-stochastic analogue of the celebrated result by Dubins and Schwarz about reduction of continuous martingales to Brownian motion via time change. We consider an idealized financial security with continuous price path, without making any stochastic assumptions. It is shown that typical price paths possess quadratic variation, where "typical" is understood in...

Published / Preprint: Asymmetric Information about Collateral Values

Posted: 04 May 2015 12:08 AM PDT

I empirically analyze credit market outcomes when competing lenders are differentially informed about the expected return from making a loan. I study the residential mortgage market, where property developers often cooperate with vertically integrated mortgage lenders to offer financing to buyers of new homes. I show that these integrated lenders have superior information about the construction...
