This paper re-examines the optimal tax design problem (income and commodities) in the presence of externalities. The nature of the second-best, and the choice of the tax instruments, are motivated by the informational structure in the economy. The main results are: (i) environmental levies...

How is the optimal level of Pigouvian taxation influenced by distributive concerns? With second-best instruments, a higher level of income redistribution calls for a lower level of Pigouvian taxation. More redistribution implies higher distortions from income taxation. Pigouvian tax revenues...

We study the impact of endogenous longevity on optimal tax progressivity and inequality in an overlapping generations model with skill heterogeneity. Higher tax progressivity decreases both the longevity gap and net income inequality, but at the expense of lower average lifetime and lower...

We examine the effect of addictive behavior on a socially optimal environmental tax. If utility in part depends on past consumption and individuals are time-consistent, the socially optimal environmental tax is shown to be equal to the conventional Pigovian tax. In a second-best world where the...

In most coastal developing countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could...

We present an exercise in empirical optimal taxation for European countries from three areas: Southern, Central and Northern Europe. For each country, we estimate a microeconometric model of labour supply for both couples and singles. A procedure that simulates the households' choices under...

The elasticity of taxable income is a key tax policy parameter that plays an important role in the formulation of tax and transfer policy. This paper extends work by Kemp (2019) by using a new panel of individual tax returns and the phenomenon of 'bracket creep' to produce updated estimates of...
