This paper derives a multibeta representation theorem for pricing assets using arbitrary reference variables that are not necessarily the true factors. Under this theorem, the upper bound on pricing deviations depends upon the correlations not only between the reference variables and the factors...

It is well known that the various formulas for the duration of a bond give inaccurate results. Their accuracy can be improved by the addition of extra elements, such as convexity or duration vectors. But the results remain inaccurate. A recent paper proposed a new formula for the duration of a...

We propose a new structural form methodology for understanding the fluctuations and predictability of volatilities and covariances of asset returns. In our model, a representative agent learns about the joint movements in inflation and real earnings through business cycles. We extract investors'...

We derive an intertemporal capital asset pricing model with multiple assets and heterogeneous investors, and explore its implications for the behavior of trading volume and asset returns. Assets contain two types of risks: market risk and the risk of changing market conditions. We show that...

In this study we examine a causal relationship between series of returns and traded volumes in high-frequency data. Our analysis is based on the methodology of Ghysels, Gourieroux and Jasiak (2000), who develop a qualitative framework in which dynamics of financial series are restricted to...

Investors rebalance their portfolios as their views about expected returns and risk change. We use empirical measures of portfolio rebalancing to back out investors views, specifically views about the state of the economy. We show that aggregate portfolio rebalancing across equity sectors is...

In this paper we extend the Capital Asset Pricing Model (CAPM) to include the case where investors allocate a part of their funds in n risky assets while the rest funds are kept as cash that generates no interest. This more general version of the model, which has practical relevance to...

I study the liquidity of global stock exchanges and how it determines cross sectional returns on stock portfolios of the exchanges. I measure liquidity by turnover ratio computed as value of shares traded over the market capitalization. I obtain data from FIBV, an association of global stock...

We provide simple methods of constructing known results. At the core of our methods is the identification of a simple concise basis that spans the Capital Market Line (CML). We show that a portfolio whose risky assets weights are the product of the inverse variance-covariance matrix of...

A simple framework is developed to analyze the important role of the bond market for the welfare of a long horizon small investor when both inflation and the real interest rate are stochastic. Closed form solutions for investor utility in different settings are used to show that the welfare loss...
