In 2008, Epstein and Schneider formulated a microstructure-inspired theory in which one could determine price volatility through a number of other market parameters such as asset volatility, risk free rate and dividend rate. A particular feature of the Epstein-Schneider theory is an extremely...

This paper proposes and motivates a dynamical model of the Chinese stock market based on a linear regression in a dual state space connected to the original state space of correlations between the volume-at-price buckets by a Fourier transform. We apply our model to the price migration of...

There is not much doubt in the public mind that the dot-com boom on NASDAQ in the end of 90s represented a bubble. Indeed, major violations of rationality were observed. For instance, some dot-coms, which terminated their business still held positive market value. A market cap of the Internet...

It has been long recognized that endogenous default probabilities cannot explain spreads between corporate and the riskless bonds. Recently, this issue has been subjected to rigorous scrutiny. Previous studies have found that for investment-grade debt, structural models explain only 15-25% of...

The method of the Wigner-Ville function proposed by Wigner, (1932) and Ville (1947) is widely used in quantum statistical mechanics and signal processing and historically preceded the continuous-time wavelets. (Gabor, 1946) Here it is proposed for the studies of the financial time series. One of...

The extremely useful method of Malliavin calculus has not yet gained adequate popularity because of the complicated analytical apparatus of this method. The author attempts here to propose a simplified algebraic formalism similar to Malliavin calculus, but based on the notion of...

The notion of “relativistic finance” became ingrained in public imagination and has been asserted in many mass-media reports. Yet, despite an observed drive of the most reputable Wall Street firms to establish their servers ever closer to the trading hubs, there is surprisingly little...

The manipulation of the LIBOR by a group of banks became one of the major blows to the remaining confidence in the finance industry (e.g. Department of Justice, 2012). Yet, despite an enormous amount of popular literature on the subject, rigorous time-series studies are few. In my paper, I...
