The US economy is often referred to as the “banker to the world,” due to its unique role in supplying global reserve assets and funding foreign risky investment. This paper develops a general equilibrium model to analyze and quantify the contribution of this role to rising wealth...

Autonomous demand shock affects consumption spending. Variation in consumption spending contributes to the volatility in aggregate demand. As the investor is risk averse, volatility of aggregate demand reduces investment. Government injects monetary noise to reduce the volatility in aggregate...

This paper investigates quantitative significance of liquidity constraints for asset prices and monetary policy in a monetary economy version of Kiyotaki and Moore (2005). Motivated by the lack of commitment in the intertemporal asset trade, the model economy features limited resalability of...

We develop an asset pricing model with external habit formation. The model predicts that the effect of consumption shocks on the equity premium depends on the business cycle. We test this empirical implication using a VAR model of the U.S. postwar economy whose parameters are estimated...

We analyze optimal monetary policy and its implications for asset prices, when aggregate demand has inertia and responds to asset prices with a lag. If there is a negative output gap, the central bank optimally overshoots aggregate asset prices (asset prices are initially pushed above their...

We develop a model of asset pricing assuming that investor's behavior is habit forming. The model predicts that the effect of consumption growth shocks on the risk premium depends on the business cycle phase of the economy. This empirical implication is tested with a Markov-switching VAR model...

We empirically show across several broad asset classes that sectoral wealth shares do not positively correlate with their risk premia---a first-order prediction of canonical equilibrium models. We then analyze the roles mean-variance and hedging demand play in accounting for sectoral shifts...

Optimal investment of firms implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of...

We document the empirical fact that asset prices in the consumption-goods and investment-goods sector behave almost identically in the US economy. In order to derive the cyclical behavior of the equity returns in these two sectors, we consider a standard two-sector real-business cycle model with...
