This paper identifies conditions under which, starting from any tax-distorting equilibrium, destination- and origin-based indirect tax-harmonizing reforms are potentially Pareto improving in the presence of global public goods. The first condition (unrequited transfers between governments)...

This paper shows that the welfare implications of indirect tax harmonization in a two-country imperfectly competitive framework, are, in general, indeterminate in the presence of public goods: Both countries can be made either worse off or better off. This holds under both the destination and...

This paper using a trade model of imperfect competition and product differentiation, examines the welfare effects of two popular tariff-tax reforms: (i) a tariff cut combined with an equal increase in the consumption tax and (ii) a tariff cut combined with an increase in the consumption tax that...

This paper shows that--in contrast to unit taxation--horizontal and vertical externalities that exist in federations are ambiguous in sign when taxation is ad-valorem. Their balance, however, depends on the marginal valuation of lower-level government and federal public goods.

In OLG economies with life-cycle saving and exogenous growth, competitive equilibria in general fail to achieve optimality because individuals accumulate amounts of physical capital that differ from the one that maximizes welfare along a balanced growth path (the Golden Rule). With human...

This article deals with the question of the equivalence between consumption taxationand wage income taxation. It is argued that when individuals behave according to strict life-cycle reasons, these taxes are not equivalent in either of the standard senses. Although a balanced-budget increase in...
