We investigate whether the effect of liquidity on equity returns can be attributed to the liquidity level, as a stock characteristic, or a market wide systematic liquidity risk. We develop a CAPM liquidity-augmented risk model and test the characteristic hypothesis against the systematic risk...

The current financial crisis has made it abundantly clear that business cycle modeling can no longer abstract from financial factors. It is also clear that the current standard approach of modeling labor markets without explicit unemployment has its limitations. We extend what is becoming the...

A comparative analysis of the existing model of financial market regulation and the model put forth by the Bank of Russia within the framework of the Draft Federal Law ‘On Self-Regulating Organizations in the Field of Financial Markets' indicates that the Bank of Russia is creating a new...

A growing share of the world's trading activity is generated by algorithmic investment strategies. Algorithms require development, backtesting, and investors that assume the initial performance risk. Evaluating the likelihood that backtested strategies will maintain their risk return profile in...

Calibrating a trading rule using a historical simulation (also called backtest) contributes to backtest overfitting, which in turn leads to underperformance. In this paper we propose a procedure for determining the optimal trading rule (OTR) without running alternative model configurations...

NWW Concept (North & all, 2009) determines the necessary threshold conditions for the transition from Limited Access Orders (LAO) to Open Access Orders (OAO). In this article, I offer a sufficient criterion for such a transition. What are the conditions under which a rent-seeking behavior...

Mean-Variance portfolios are optimal in-sample, however they tend to perform poorly out-of-sample (even worse than the 1/N naïve portfolio!) We introduce a new portfolio construction method that substantially improves the Out-Of-Sample performance of diversified portfolios.The full paper is...

The current crisis has triggered significant debate concerning economic theory and policy. Largely absent from this debate is an informed discussion of the methods used by economists in analysing the economy and formulating their proposals. But method matters. Here I argue that current academic...

Using positive semidefinite supOU (superposition of Ornstein-Uhlenbeck type) processes to describe the volatility, we introduce a multivariate stochastic volatility model for financial data which is capable of modelling long range dependence effects. The finiteness of moments and the second...
