The inflation risk premium (IRP) in the U.S. stock market varies over time. We use individual stocks to estimate the IRP, because this provides us with a heterogeneous cross-section of exposures. We find that the IRP is a significant -5.5% since the 1960s, but reverses to an insignificant...

The dissertation consists of three essays in asset pricing. Chapter I is motivated by the recent surge in institutional investment in commodity futures markets. The chapter studies how commodity risk is priced in stock and futures markets and asks whether this risk premium is time-varying with...

I give necessary and sufficient conditions under which interest-rate feedback rules eliminate aggregate instability by inducing a globally unique optimal equilibrium in a canonical New Keynesian economy with a binding zero lower bound. I consider a central bank that initially keeps interest...

We find that the relation between state variables, such as the t-bill rate and term spread, and consumption growth is time-varying. In the cross-section of US stocks, risk premia for exposure to state variables vary over time accordingly. When a state variable predicts consumption strongly...

We study the returns to characteristic-sorted portfolios up to five years after portfolio formation. Among a set of 56 characteristics, we find large pricing errors between the contemporaneous returns of new and old sorts, where new sorts use the most recent observations of firm characteristics....

We find that commodity futures returns contain information relevant to stock market returns and macroeconomic fundamentals for a large number of countries. Commodity futures returns predict stock market returns in 59 out of 70 countries and macroeconomic fundamentals in 62 countries. This...
