This paper investigates dynamic completeness of financial markets in which the underlying risk process is a multi-dimensional Brownian motion and the risky securities dividends geometric Brownian motions. A sufficient condition, that the instantaneous dispersion matrix of the relative dividends...

I establish a necessary and sufficient condition for the securities' market to be dynamically-complete in a single-commodity, pure-exchange economy with many Lucas' trees whose dividends are geometric Brownian motions. Even though my analysis is based upon the representative-agent version of...

Standard consumption-based asset pricing models focus on the consumption risk, seen as the only source of fluctuations and information about risk for the informed investor. These models, however, can account for high expected excess stock return only when assuming implausible relative risk...

We provide a new theoretical framework for estimating the price sensitivities of a trading position with regard to five underlying factors in jump-diffusion models using jump times Poisson noise. The proposition that results in a general solution is mathematically proved. The general solution...

We study the pricing factor structure of Italian equity returns. Using 25 years of data, we focus on a classical four factors model. A two step empirical analysis is provided where first we estimate an unrestricted multi-factor model to test if there is any evidence of misspecification. Then, we...

Purportedly consistent with “risk parity” (RP) asset allocation, recent studies document compelling “low risk” trading strategies that exploit a persistently negative relation between Sharpe ratios (SRs) and maturity along the U.S. Treasury (UST) term structure. This paper extends this...

Existing literature continues to be unable to offer a convincing explanation for the volatility of the stochastic discount factor in real world data. Our work provides such an explanation. We do not rely on frictions, market incompleteness or transactions costs of any kind. Instead, we modify a...

We propose a novel approach to cross-sectional equities sample selection, derived from best market practice in index construction and focused on investability. Using the U.K. market as a template, we first demonstrate how the popular Datastream dataset is plagued by data deficiencies that would...
