This paper assesses the quantitative importance of a number of sources of income risk for household welfare and precautionary saving. To that end I construct a lifecycle consumption model in which household income is subject to shocks associated with disability, health, unemployment, job...

There is a large literature showing that the self-employed underreport their income to tax authorities. In this paper, we quantify the extent to which the self-employed also systematically underreport their income in U.S. household surveys. To do so, we use the Engel curve describing the...

Theories of fiscal illusion and political competition have different implications for (i) the causal relationships between taxes and spending, and (ii) government size. These are tested using data from u.s. states from 1950 to 1990. We find evidence that greater political competition generally...

Previous literature demonstrates that in a computational life cycle model the optimal tax on capital is positive and large. Given the computational complexities of these overlapping generations models it is helpful to determine the relative importance of the economic factors driving this result....

This paper considers the impact of endogenous human capital accumulation on optimal tax policy in a life cycle model. Including endogenous human capital accumulation, either through learning-by-doing or learning-or-doing, is analytically shown to create a motive for the government to use...

In a two-country world with perfect capital markets and no taxes, the existence of purchasing power parity is fully consistent with interest party and the equalization of real interest rates across countries. In such a world, changes in anticipated inflation in either country will not alter the...

The informal sector, which produces legal goods but does not comply with government regulations, is a functioning part of all economies, with a proportion of the labor force ranging from 17 percent in OECD countries to 60 percent in developing countries. Using a dynamic model that includes an...
