We develop measures of time-varying risk aversion and economic uncertainty that are calculated from financial variables at high frequencies. We formulate a dynamic no-arbitrage asset pricing model for equities and corporate bonds. The joint dynamics among asset-specific cash flows, macroeconomic...

The real options framework has been used extensively to analyze the timing of investment under uncertainty. While standard real options models assume that agents possess a constant rate of time preference, there is substantial evidence that agents are very impatient about choices in the...

The VIX, the stock market option-based implied volatility, strongly co-moves with measures of the monetary policy stance. When decomposing the VIX into two components, a proxy for risk aversion and expected stock market volatility ("uncertainty"), we find that a lax monetary policy decreases...

This paper investigates the statistical properties of high frequency nominal exchange rates and forward premiums in the context of a dynamic two-country general equilibrium model. Primary focus is on the persistence, variability, leptokurtosis and conditional heteroskedasticity of exchange rates...

We identify the relative importance of changes in the conditional variance of fundamentals (which we call %u201Cuncertainty%u201D) and changes in risk aversion (%u201Crisk%u201D for short) in the determination of the term structure, equity prices and risk premiums. Theoretically, we introduce...

It appears that volatility in equity markets is asymmetric: returns and conditional volatility are negatively correlated. We provide a unified framework to simultaneously investigate asymmetric volatility at the firm and the market level and to examine two potential explanations of the...

Emissions control cannot address the consequences of global warming for weather disasters until decades later. We model regional-level mitigation or adaptation, which reduces disaster risks to capital in the interim. Mitigation depends on belief regarding the adverse consequences of global...

We extract aggregate supply and aggregate demand shocks for the US economy from macroeconomic data on inflation, real GDP growth, core inflation and the unemployment gap. We first use unconditional non-Gaussian features in the data to achieve identification of these structural shocks while...

We develop an integrated theory of investment, seasoned equity offerings (SEOs), liquidation, and corporate savings under uncertainty for a financially constrained firm, which features endogenous growth options, abandonment options, and payout policies. Facing costly external financing, the firm...
