We use a fully-specified neoclassical model augmented with costly external equity as a laboratory to study the relations between stock returns and equity financing decisions. Simulations show that the model can simultaneously and in many cases quantitatively reproduce: procyclical equity issuance;...

This paper studies conditions under which demand-side shocks can generate realistic business cycles in RBC models. Although highly persistent demand shocks are necessary for generating procyclical investment, variable capacity utilization and habit formation can reduce the required degree of...

This paper extends the standard Mehra-Prescott one-good, pure exchange economy to the case where agents are assumed to be in ignorance of the true transition probabilities of the growth rate of output and to learn them using bayes rule. The main conclusion is that the proposed bayes model yields...

This paper augments the neoclassical growth model to study the macroeconomic effects of idiosyncratic investment risk. The general equilibrium is solved in closed form under standard assumptions for preferences and technologies. Relative to complete markets, the steady state is characterized by...

This paper studies equilibrium effects of fiscal policy disturbances within a dynamic general equilibrium model where tax evasion and underground activities are explicitly incorporated. There are three main results. (i) The underground sector mitigates the distortionary impact of fiscal...

I develop a dynamic model of corporate investment with taxes, costly equity and debt financing, agency conflicts between shareholders and managers, and a parameterized time-varying pricing kernel. The framework allows me to explore both the cross section of returns and firms' financing choices....

Shifts in the long-run rate of productivity growth are difficult, in real time, to distinguish from transitory fluctuations. We analyze the evolution of forecasts of long-run productivity growth during the 1970s and 1990s and examine in a dynamic general equilibrium model the consequences of...

We use a production-based asset pricing model to investigate whether financial market imperfections are quantitatively important for pricing the cross-section of returns. Specifically, we use GMM to explore the stochastic Euler equation restrictions imposed on asset returns by optimal investment...

Survey and option data are used to take a fresh look at the equity premium puzzle. Survey data on equity returns (Livingston survey) shows much lower expected excess returns than ex post data. At the same time, option data suggests that investors tend to overestimate the volatility of equity...

This paper studies if the consumption-based asset pricing model can explain the cross-section of expected returns. The CRRA model and several refinements (habit persistence and idiosyncratic shocks) all imply that the conditional expected return is linearly increasing in the asset's conditional...
