This paper examines if (and how) continuous-time trading renders dynamically-complete a financial market in which the underlying risk process is a Brownian motion and the securities pay dividends that are proportional to geometric Brownian motions. A sufficient condition, that the instantaneous...

Using a general equilibrium model with endogenous growth, I show that risk to human capital leads to a “Value” premium in equity returns. In particular, firms with relatively more firm-specific human capital or more positive covariance between asset growth and returns on human capital are...

We quantify the effect of financial leverage on stock return volatility in a dynamic general equilibrium economy with debt and equity claims. We study the effects of financial leverage on the market portfolio, and on a small firm with idiosyncratic and market risk. In an economy with both a...

We combine general equilibrium theory and théorie générale of stochastic processes to derive structural results about equilibrium state prices.

We develop a general equilibrium model of a production economy which has a risky production technology as well as a growth option to expand the scale of the productive sector of the economy. We show that when confronted with growth options, the representative consumer may sharply alter...

In a single-commodity, pure-exchange, representative-agent economy with many Lucas' trees whose dividends are geometric Brownian motions, I study the comparative statics of the prices of these assets with respect to the current Brownian realization. As is well-known, due to wealth effects, a...

The covariance between US Treasury bond returns and stock returns has moved considerably over time. While it was slightly positive on average in the period 1953--2009, it was unusually high in the early 1980''s and negative in the 2000''s, particularly in the downturns of 2000--02 and 2007--09....
