In standard models wages are too volatile and returns too smooth. We make wages sticky through infrequent resetting, resulting in both (i) smoother wages and (ii) volatile returns. Furthermore, the model produces other puzzling features of financial data: (iii) high Sharpe Ratios, (iv) low and...

Correlations of monthly, quarterly and annual consumption growth rates, calculated from novel weekly Gallup consumption data, with the equity premium are high – 13%, 44% and 54% at monthly, quarterly and yearly frequency. The power utility consumption CAPM prices the sample average annual...

We examine a trivariate time series model that is subject to a regime switch, where the shifts are governed by an unobserved, two-state variable that follows a Markov process. The analysis is performed in a Bayesian framework developed by Albert and Chib (1993), where the unobserved states are...

We present evidence that the mix of transitory and permanent shocks to consumption is changing over time. We study implications of this finding for asset prices. The uncovered dynamics of consumption implies modestly upward sloping real bond and equity curves, upward sloping nominal yield curve,...

We examine implications of introducing parameter uncertainty in endowment and production economies for index option premiums. We estimate two-state models of consumption and productivity growth using post-war U.S. data and allow for rational learning about unknown persistence of economic growth....

This paper investigates the interdependence between the risk-pooling activity of the financial sector and: output, consumption, risk-free rate, and Sharpe ratio in a dynamic general equilibrium model of a productive economy. Due to their exposure to idiosyncratic shocks and market segmentation,...

This paper investigates the macroeconomic and asset pricing consequences of the upward trend in financial market participation observed in the U.S. since the late 1980s. In a limited participation two-agent Real Business Cycle model where stockholders feature external habit preferences, higher...

We propose a tractable framework that incorporates endogenous default in a continuous time setting and assesses the interaction of default and leverage. In our heterogeneous agent model, productive experts face leverage constraints and aggregate risk, borrow from less productive households and...

We study the relationship between intermediation efficiency and the macroeconomic dynamics within a tractable real business cycle model with financial frictions. Households finance firms but, due to restricted equity market participation, cannot pool their idiosyncratic risks. Financial...

We model investment options as intangible capital in a production economy in which younger vintages of assets in place have lower exposure to aggregate productivity risk. In equilibrium, physical capital requires a substantially higher expected return than intangible capital. Quantitatively, our...
