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...

Financial economists have long been interested in the empirical relation between the conditional mean and conditional volatility of excess stock market returns, often referred to as the risk-return relation. Unfortunately, the body of empirical evidence on the risk-return relation is mixed and...

One fundamental issue in the study of market microstructures is that of price discovery. While most existing studies focus on the trading period, little is known whether and how much the non-trading period contributes to the price discovery. This paper offers a new perspective on the price...

Value stocks have higher average returns than growth stocks. At the same time, the duration of value stocks' cash flows is considerably shorter than that of growth stocks. We show that when investors can fully distinguish short- and long-run consumption risk components of dividend growth...

Evidence of stock return predictability by financial ratios is still controversial, as documented by inconsistent results for in-sample and out-of-sample regressions and by substantial parameter instability. This paper shows that these seemingly incompatible results can be reconciled if the...

Investment is often irreversible, especially at the aggregate level. This paper proposes and solves a general equilibrium model of technology adotpion when investment in the new technlogy is irreversible. In contrast to prior research, we consider a setup where the returns on technology adoption...

The main contribution of this work is to provide a dynamic general equilibrium model of asset allocation, allowing to reconcile economic theory with several puzzling contradictions recently pointed out in the literature: (i) the asset allocation puzzle, (ii) the observed time-variation in...

Consider a collection of agents with stochastically fluctuating heterogeneous endowments. It seems natural that credit is the appropriate market mechanism for insuring such fluctuations: individuals save when endowment is high, and deplete their savings or borrow when their endowment is low. The...

We assess the predictive accuracy of a large number of multivariate volatility models in terms of pricing options on the Dow Jones Industrial Average. We measure the value of model sophistication in terms of dollar losses by considering a set 248 multivariate models that differ in their...
