How should aggregate public expenditures be traded off against their financing costs? We incorporate public expenditures into a standard neoclassical growth setup with model policy choice as made by a government choosing tax rates and spending so that the resulting competitive equilibrium...

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...

In this paper we address the time-inconsistency of optimal debt policy—the incentive for a current government to “manipulate interest ratesâ€â€”raised in Lucas and Stokey’s celebrated 1983 paper. The literature that followed suggested various ways to fully overcome...

Where the state evolves according to a discrete-state Markov chain, we sustain Lucas and Stokey's debt structure dynamics by having it emerge sequentially as the unique outcome of a sequence of choices made by two sequences of independent government departments. Each period a tax authority sets...

We examine whether Brazilian sovereign spreads of over 20% in 2002 could be due to contagion from Argentina or to domestic politics, or both. Treating unilateral debt restructuring as a policy variable gives rise to the possibility of self-fulfilling crisis, which can be triggered by contagion....

All developed countries have government debt, usually a sizeable proportion of output. This paper proposes that governments that cannot commit to future policy choices face a trade-off that explains the level of debt. On the one hand, the government would like to increase debt and delay...
