We estimate the trend in the transitory variance of male earnings in the U.S. using the Michigan Panel Study of Income Dynamics from 1970 to 2004. Using both an error components model as well as simpler but only approximate methods, we find that the transitory variance started to increase in the...

Different beliefs about how fair social competition is and what determines income inequality, influence the redistributive policy chosen democratically in a society. But the composition of income in the first place depends on equilibrium tax policies. If a society believes that individual effort...

This paper examines several aspects of the debate about the causes of the U.S. current account deficit in the 1980's. It surveys several popular explanations before developing two theoretical models of international capital flows. The first model is Ricardian, and it extends the analysis of...

Studies of the firm's demand for factor inputs often assume a constant rate of utilization of the inputs and ignore the fact that the firm can simultaneously choose the level and the rate of utilization of its inputs. In particular, the literature on dynamic factor demand models has, until...

Most countries have automatic rules in their tax-and-transfer systems that are partly intended to stabilize economic fluctuations. This paper measures how effective they are. We put forward a model that merges the standard incomplete-markets model of consumption and inequality with the new...

We study the evolution of the U.S. current account in a two-country dynamic stochastic endowment model in which a single non-state contingent bond is the only internationally traded asset. The paper focuses on the world `saving glut' as the primary cause of continual deterioration in the current...

Local governments can provide services with their own employees or by contracting with private or public sector providers. We develop a model of this quot;make-or-buyquot; choice that highlights the trade-off between productive efficiency and the costs of contract administration. We construct a...

The purpose of this paper is to apply the theory of Lie transformation groups as developed by the first author, and derive a testable model of production and technical change. The econometric model is then applied to data derived by F. Gollop and D. Jorgenson for U.S. manufacturing industries...

This paper investigates three hypotheses to account for the observed shifts in U.S. relative wages of less educated compared to more educated workers between 1967 and 1992: increased import competition, changes in the relative supplies of labor of different education levels and changes in...

“Pass-through” businesses like partnerships and S-corporations now generate over half of U.S. business income and account for much of the post-1980 rise in the top- 1% income share. We use administrative tax data from 2011 to identify pass-through business owners and estimate how much tax...
