Chapter Contribution The main purpose of this chapter is to shed more light into the challenging small business (SME) task of securing adequate and appropriate funding for continued viability. Access to finance is of fundamental importance to SME survival, invariably it involves working capital...

Most discrete time literature uses the beta that results from a regression of an asset's simple returns on various factors to quantify risk. The departing point for this thesis is the consistent use of log-returns. When log-returns are considered, the relevant measure of systematic risk becomes...

Purpose This paper aims to present the results of further investigating the Polimenis (2012) stochastic model, which aims to decompose the stock return evolution into positive and negative jumps, and a Brownian noise (white noise), by taking into account different noise levels. This paper...

Purpose – This paper aims to enhance a co-skew-based risk measurement methodology initially introduced in Polimenis, by extending it for the joint estimation of the jump betas for two stocks. Design/methodology/approach – The authors introduce the possibility of idiosyncratic jumps and...

A model that realistically defines market liquidity and depth is introduced. Liquidity is the expected rate of order execution in shares per minute. Depth is the average density of the limit order book in shares per dollar. Illiquid markets tend to exhibit longer execution delays and indirectly...
