It has recently been shown that incorporating "keeping up with the Joneses" preferences into a prototypical two-ability-type optimal nonlinear taxation model leads to higher marginal income tax rates for both types of agents. Specifically, the high-skill type faces a positive marginal income tax...

This paper examines a dynamic model of nonlinear income taxation in which the government cannot commit to its future tax policy, and individuals are quasi-hyperbolic discounters who cannot commit to future consumption plans. The government has both paternalistic and redistributive objectives,...

This paper addresses the question as to whether it is optimal to use separating or pooling nonlinear income taxation, or to use linear income taxation, when the government cannot commit to its future tax policy. We consider both two- period and inÖnite-horizon settings. Under empirically...

This paper examines a dynamic model of nonlinear income taxation in which the government cannot commit to its future tax policy, and individuals are quasi-hyperbolic discounters who cannot commit to future consumption plans. The government uses its taxation powers to maximise a utilitarian...

Previous studies that examine the simultaneous setting of income taxation and education policy have overwhelmingly concluded that optimal education policy should be regressive. In this paper, we depart from the existing literature by studying a dynamic model in which the government may choose to...

Despite using a variety of models and assumptions, the existing literature has overwhelmingly concluded that education policy should be regressive. In this paper, we examine a two-period model in which the government may impose non- linear taxes on both labour income and education expenditures....

This paper examines an infinite-horizon model of dynamic nonlinear income taxation in which there exists a small probability that the government cannot commit to its future tax policy. In this "loose commitment" environment, we find that even a little uncertainty over whether the government can...

This paper examines a two-period model of optimal nonlinear income taxation with learning-by-doing, in which second-period wages are an increasing function of first-period labour supply. We consider the cases when the government can and cannot commit to its second-period tax policy. In both...

This paper presents some theory and evidence on the implications of sudden currency depreciations for output and inflation. It identifies some of the characteristics shared by countries which have suffered falling output in the aftermath of a currency crisis, and it presents a small model which...
