|May 2007||Cointegration and Consumption Risks in Asset Returns|
with Ravi Bansal, Dana Kiku: w13108
We argue that the cointegrating relation between dividends and consumption, a measure of long run consumption risks, is a key determinant of risk premia at all investment horizons. As the investment horizon increases, transitory risks disappear, and the asset's beta is dominated by long run consumption risks. We show that the return betas, derived from the cointegration-based VAR (EC-VAR) model, successfully account for the crosssectional variation in equity returns at both short and long horizons; this is not the case when the cointegrating restriction is ignored. Our evidence highlights the importance of cointegration-based long run consumption risks for financial markets.

|December 2003||Gold, Fiat Money, and Price Stability|
with Michael D. Bordo, William T. Gavin: w10171
Which monetary regime is associated with the most stable price level? A commodity money regime such as the classical gold standard has long been associated with long-run price stability. But critics of the day argued that the regime was associated with too much short-run price variability and argued for reforms that look much like modern versions of price-level targeting. In this paper, we develop a dynamic stochastic general equilibrium model that we use to examine price dynamics under four alternative regimes. They are the gold standard, Irving Fisher's compensated dollar proposal, and two regimes with paper money in which the central bank uses an interest rate rule to run monetary policy. In the first, the central bank uses an interest rate rule to target the price of gold. In the secon...
