This note examines the accuracy of methods that are commonly used to approximate AR(1)-processes with discrete Markov chains. The quadrature-based method suggested by Tauchen and Hussey (1991) generates excellent approximations with a small number of nodes when the autocorrelation is low or...

This paper demonstrates that increased optimism about future productivity can generate an immediate economic expansion in a neoclassical model with vintage capital and variable capacity utilization. Previous research has documented that standard neoclassical models cannot generate a simultaneous...

The Ramsey optimal taxation theory implies that the tax rate on capital income should be zero in the long run. This result holds even if the social planner only cares about workers that do not hold assets, or if the planner only cares about any other group in the economy. This paper demonstrates...

This paper examines how variations in labor supply can be used to self-insure against wage uncertainty, and the impact of such self-insurance on precautionary saving. The analytical framework is a two-period model with saving and labor-supply decisions where preferences are consistent with...

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a liquidity constraint. I first show that the equilibrium capital stock in an economy without uncertainty,...

In this note, I examine how the responsiveness of the Swedish public budget to business-cycle conditions has developed between 1998 and 2009. I document substantial changes in three components behind the budget elasticity: (i) the average level of personal income taxes has fallen substantially,...

We document a clear increase in Swedish earnings inequality in the early 1990s. Inequality in disposable income and earnings net of taxes and transfers also increased, but much less than the increased inequality in pre-government earnings. These different developments are most likely explained...

The labor-supply elasticity is a central element in many macroeconomic models. We argue that assumptions underlying previous econometric estimates of the intertemporal labor supply elasticity are inconsistent with incomplete markets economies. In particular, if the econometrician ignores...

We use the neoclassical growth framework to model international capital flows in an economy with exogenous demographic change. We compare model implications and actual current account data and find that the model explains a small but significant fraction of capital flows between OECD countries,...
