Let Q be the set of equivalent martingale measures for a given process S, and let X be a process which is a local supermartingale with respect to any measure in Q. The optional decomposition theorem for X states that there exists a predictable integrand ф such that the difference...

This article documents how the changing composition of U.S. publicly traded firms has prompted a decline in the long-run mean of the aggregate dividend-price ratio, most notably since the 1970s. Adjusting the dividend-price ratio for such changes resolves several issues with respect to the...

We examine overconfidence among equity mutual fund managers. While overconfidence has been extensively documented among retail investors, evidence from professional investors is scarce. Consistent with theories of overconfidence, we find that fund managers trade more after good past performance....

We relate Schumpeter's notion of creative destruction to asset pricing, thereby offering a novel explanation of size and value premia. We argue that small-value firms are more likely to be destroyed by serendipitous invention activity, and investors demand higher expected returns for bearing...

The pricing of financial assets, this paper contends, it does not consist only in assessing a technical value from a valuation model and then calibrating such value by looking at the market. In order to sharpen up this complex process we are going to handle, firstly, a valuation procedure that...

The purpose of this paper is to model differential rates over residual information sets, so as to shape transactional algebras into operational grounds. Firstly, simple differential rates over residual information sets are introduced by taking advantage of finite algebras of sets. Secondly,...

De acuerdo a la literatura el precio de un activo (financiero o real) experimenta una burbuja si su precio de mercado se encuentra desajustado de manera persistente en el tiempo con respecto a su valor intrínseco o fundamental. En un contexto de racionalidad y eficiencia es difícil aceptar la...

Although the standard trading arbitrage model provides with simple settings and adjustment mechanisms so as to take profit whenever an arbitrage opportunity comes up, empirical evidence has been piling up showing that this point of view suffers from many downsides, leaving distinctive issues...

This paper applies the dichotomous theory of choice by Zou (2000a) tothe analysis of investmentstrategies and security markets. Issues concerning individualoptimality, (approximate) arbitrage,capital market equilibrium, and Pareto efficiency are studied undervarious market conditions. Among the...

The long-run consumption risk model provides a theoretically appealing explanation for prominent asset pricing puzzles, but its intricate structure presents a challenge for econometric analysis. This paper proposes a two-step indirect inference approach that disentangles the estimation of the...
