Understanding the origins of wealth inequality is critical in the debate over what, if anything, to do about it. In this note, we propose a simple model which is still rich enough to reproduce observed patterns of wealth inequality. We call it the Concentrated Asset Betting (CAB) model. A key...

With 30% of the world's investment grade sovereign bonds trading at sub-zero yields, there is a growing acceptance that negative interest rates are the 'new normal.' Even very low probabilities of sustained negative interest rates in the future leads to incredibly high Expected Values for...

The paper proposes a new integrated conditional moment test for model adequacy related to the tests studied in Bierens (1982) and Bierens and Ploberger (1997). The new test allows for a numerical calculation of its asymptotic distribution when the parameter estimator is asymptotically linear. We...

This note describes the background of Factor investing in its Smart Beta form, and discusses the reasons Factor investing has become a popular investing style. We also discuss a number of reasons for skepticism regarding forward-looking expected returns

This article presents a new model for valuing a credit default swap (CDS) contract that is affected by multiple credit risks of the buyer, seller and reference entity. We show that default dependency has a significant impact on asset pricing. In fact, correlated default risk is one of the most...

I show that a congruent, parsimonious, encompassing model discovered using David Hendry's econometric modelling approach and Autometrics can overcome the many inadequacies of the typical static models of US Treasury returns regressed on macroeconomic announcements. The typical specification...

Classical quantitative finance models such as the Geometric Brownian Motion or its later extensions such as local or stochastic volatility models do not make sense when seen from a physics-based perspective, as they are all equivalent to a negative mass oscillator with a noise. This paper...

Fixed income investors favor higher yields with lower risk. Our objective in this paper is to outline an active fixed income strategy that maximizes yield and is protected against major risk factors affecting fixed income securities. In particular, we look at interest rate risk, credit risk,...
