This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to 'unretire', i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

We analyze non-cooperative commodity taxation in a symmetric two- country trade model characterized by monopolistic competition and inter- national firm and capital mobility. In this setting, taxes in one country affect foreign welfare through the relocation of mobile firms and through changes...

This paper studies non-cooperative commodity taxation in a trade model with im-perfect competition and trade costs. Nationally optimal tax policy simultaneously tries to correct the domestic distortion from imperfect competition and to shift rents to the home country. Importantly, this trade-off...

The Atkinson-Stiglitz Theorem states that if labor is weakly separable from goods in household utility functions, differential commodity taxation should not be not part of an optimal redistributive tax system. This Theorem, which is arguable the most policy-relevant result to come out of the...

This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to unretire, i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

The paper analyzes strategic commodity taxation in a model with trade in a single private good which is simultaneously imported by consumers of a high-tax region and exported by its producers. Conditions for the existence of a Nash equilibrium are given and an asymmetry is introduced through...

The paper analyzes the implications of allowing for trade deflection under the restricted origin principle. It is shown that (a) producer trade deflection leads to circular trade and must be ruled out to obtain a trade equilibrium, (b) consumer trade deflection will not occur in a Nash...

Atkinson and Stiglitz show that with weakly separability, differential commodity taxes are unnecessary given an optimal nonlinear income tax. Deaton showed that with an optimal linear progressive income tax, commodity taxes are superfluous under weakly separable and linear Engel curves. Using...
