This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

This Paper analyses an overlapping generation model of public good provision under repeated voting. The public good is financed through age-dependent taxation that distorts human capital investment. Taxes redistribute income both across different skill groups and across generations. We contrast...

In this paper, we incorporate a positive theory of unemployment insurance into a dynamic overlapping generations model with search-matching frictions and on-the-job learning-by-doing. The model shows that societies populated by identical rational agents, but differing in the initial distribution...

This Paper presents a tractable dynamic general equilibrium model that can explain cross-country empirical regularities in geographical mobility, unemployment and labour market institutions. Rational agents vote over unemployment insurance (UI), taking the dynamic distortionary effects of...

This Paper provides an analytical characterization of Markov perfect equilibria in a model with repeated majority voting, where agents vote over income redistribution. The key feature of the theory is that the future constituency of redistributive policies depends positively on the current level...

We analyze a dynamic stochastic general-equilibrium (DSGE) model with an externality---through climate change---from using fossil energy. A central result of our paper is an analytical derivation of a simple formula for the marginal externality damage of emissions. This formula, which holds...

We estimate an aggregate production function with constant elasticity of substitution between energy and a capital/labor composite using U.S. data. The implied measure of energy-saving technical change appears to respond strongly to the oil-price shocks in the 1970s and has a negative medium-run...

This paper develops a model that integrates the climate and the global economy---an integrated assessment model---with which different policy scenarios can be analyzed and compared. The model is a dynamic stochastic general-equilibrium setup with a continuum of regions. Thus, it is a full...

Motivated the European debt crisis, we construct a tractable theory of sovereign debt and structural reforms under limited commitment. The government of a sovereign country which has fallen into a recession of an uncertain duration issues one-period debt and can renege on its obligations by...

This paper constructs a growth model that is consistent with salient features of the Chinese growth experience since 1992: high output growth, sustained returns on capital investments, extensive reallocation within the manufacturing sector, falling labor share and accumulation of a large foreign...
