We develop a dynamic general equilibrium model to study the impact of the 2003 dividend and capital gains tax cuts. In the model, firms are heterogeneous in productivity and make investment and financing decisions subject to capital adjustment costs, equity issuance costs, and collateral...

A capital income tax cut must in general be financed by increasing other taxes, and thus will have redistributive effects. This paper studies analytically the redistribution implied by a capital income tax cut in the Ramsey-Cass-Koopmans neoclassical growth model when agents differ in wealth and...

This paper studies whether the Rietz–Barro “disaster” model, extended for a time-varying probability of disaster, can match the empirical evidence on predictability of stock returns. It is shown that when utility is CRRA, the model cannot replicate this evidence, regardless of parameter...

This paper attempts to reconcile the high apparent aggregate elasticity of labor supply with small micro estimates. We elaborate on Rogerson’s seminal work (1988) and show that his results rely neither on complete markets nor on lotteries, but rather on the indivisibility of labor supply and...

I use a putty-clay technology to explain several asset market facts. The key mechanism is as follows: a one percent increase in revenues leads to a more-than-one percent increase in profits, since labor costs don’t move one-for-one. This amplification is greater for plants with low...

In this paper, I propose and test a simple technology-based theory of firms’ sensitivities to aggregate shocks. I show that when the elasticity of substitution between capital and labor is below unity, low profitability firms are more sensitive to aggregate shocks, i.e. to the business cycle....

Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To afford this distinction, we adopt the multiple-priors...

This paper studies consumption/saving problem under Knightian uncer- tainty in a two period setting. The multiple-priors utility model is adopted. The e®ects of income uncertainty and capital uncertainty on optimal savings are analyzed by deriving closed form solutions.
