We analytically and quantitatively examine a prominent justifi…cation for capital income taxation: goods preferred by those with high ability ought to be taxed. We study an environment where commodity taxes are allowed to be nonlinear functions of income and consumption and …find that, when...

intertemporal distortions.

In this paper, we argue that shocks that affect the private agents' ability to borrow are precisely the type of shocks that can push the economy in a liquidity trap. We show that, when preferences display prudence, these shocks tend to make consumers more cautious, leading both to lower levels...

This paper explores the role of the financial sector in facilitating the flow of funds from borrowers to lenders. Unlike in traditional models of banking, the role of financial firms in our model is not to raise funds from lenders (depositors) and use them to make loans to borrowers. Rather...

This paper studies an environment in which information aggregation interacts with investment decisions. The first contribution of the paper is to develop a tractable model of such interactions. The second contribution is to solve the model in closed form and derive a series of implications that...

and that the derivative at the balanced growth equilibrium can be computed analytically from the primitives of the model.

We build a business cycle model where employers' screening of heterogeneous workers plays a central role in determining both the flows into and out of unemployment. The model can address how differences between the US and European labor market flows affect business cycle dynamics. It provides a...

This paper presents and estimates a sticky-price model with heterogeneous households and financial frictions. Frictions in state-contingent asset markets lead to imperfect risk-sharing among households with idiosyncratic labor incomes. I study the impacts of the introduced …financial frictions...

We develop a dynamic politico-economic model of public investment where decisions can be made at several levels of government: federal, state, or county. The model predicts that in the absence of internal mobility, the higher level of government would fund all investments that present positive...
