On Consumption Bunching under Campbell-Cochrane Habit Formation
نویسندگان
چکیده
Campbell and Cochrane (1999) propose a preference speci cation that can explain a wide variety of asset pricing puzzles such as the high equity premium. They augment the basic power utility function with a time-varying subsistence level, or \habit", which is in the spirit of \catching up with the Joneses" but with a novel nonlinear mapping of consumption into habit. This paper demonstrates a surprising implication of the Campbell-Cochrane preference speci cation: consumption bunching is desirable. JEL: E21

Habit Formation and the Cross Section of Stock Returns¤
We develop an external habit persistence model where the time series of the aggregate portfolio and the cross section of stock returns are simultaneously studied and tested. By applying a slightly modi...ed version of the model of Campbell and Cochrane (1999), we obtain closed form solutions for individual securities prices and returns and a full characterizations of the dynamics of the risk-re...

This paper examines the role for tax policies in productivity-shock driven economies with \catching-up-with-the-Joneses" utility functions. The optimal tax policy is shown to a ect the economy countercyclically via procyclical taxes, i.e., \cooling down" the economy with higher taxes when it is \overheating" in booms and \stimulating" the economy with lower taxes in recessions to keep consumpti...
متن کاملThe Rodney L . White Center for Financial Research Solving Models with External Habit
Habit utility has been the focus of a large and growing body of literature in financial economics. This study investigates ways of accurately and efficiently solving the Campbell and Cochrane (1999) external habit model. Solutions for this model based on a grid of values for the state variable are shown to converge as the grid becomes increasingly fine. Convergence is substantially faster if th...
متن کاملHabit, Long-Run Risks, Prospect? A Statistical Inquiry
We use recently proposed Bayesian statistical methods to compare the habit persistence asset pricing model of Campbell and Cochrane, the long-run risks model of Bansal and Yaron, and the prospect theory model of Barberis, Huang, and Santos. We improve these Bayesian methods so that they can accommodate highly nonlinear models such as the three aforementioned. Our substantive results can be stat...
