I present a dynamic general equilibrium model in which financial interconnectedness endogenously changes over the business cycle and shapes systemic risk. To share individual risks, banks become interconnected through holding overlapping asset portfolios. Diversification reduces individual...

Why are asset prices so much more volatile and so often detached from their fundamental values? Why does the bursting of financial bubbles depress the real economy? This paper addresses these questions by constructing an infinite-horizon heterogeneous agent general equilibrium model with...

We scrutinize the impact of dividend policy on stock price volatility by considering the seminal paper of Baskin (1989). In this context, we examine the relationship between volatility and three dividend policy indicators, dividend yield, dividend payout, and stock repurchases, for 1,221 firms...

We demonstrate how it is possible to generate value for an investor with a hedge attached to the buy-and-hold strategy of a S&P 500 index fund. We study the S&P 500 index portfolio (not including dividends) and the CRSP value weighted S&P 500 index portfolio (including dividends) for...

This paper studies the importance of idiosyncratic endowment shocks for aggregate asset prices in continuous time. My generalized framework accommodates jumps and heterogeneous recursive preferences. I show that countercyclical cross-sectional risk is irrelevant to risk premia if and only if all...

Beaudry and Portier (2006) provide support for the "news view" of the business cycle, using a vector error correction model. We show that this result hinges on a cointegrating relationship between TFP and stock prices that is not stationary, thus making the estimates not reliable. If we alter...

We present a simple model that quantitatively replicates the behavior of stock prices and business cycles in the United States. The business cycle model is standard, except that it features extrapolative belief formation in the stock market, in line with the available survey evidence....
