Because policymakers may consider the state of the economy when setting taxes, endogeneity bias can arise in regression models that estimate relationships between economic variables and taxes. This paper quantifies the policy endogeneity bias and estimates the impact of R&D tax incentives on R&D...

We re-examine the optimality of tax smoothing from the point of view of frictional labor markets. Our central result is that whether or not this cornerstone optimal fiscal policy prescription carries over to an environment with labor market frictions depends crucially on the cyclical nature of...

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...

A growing body of work--both theoretical and empirical--has emphasized that unionization may be better understood as a tax on capital rather than a tax on labor. Under this "new" view, unionization unambiguously lowers investment. Using data on union certification elections, we estimate the...

Criticisms of endogenous growth models with flat rate taxes have highlighted two features that are not substantiated by the data. These models generally imply: (1) that economic growth must fall with the share of government expenditures in output across countries, and (2) that one-time shifts in...
