Consumption Taxes and Redistribution

It is relatively well known that the introduction of consumption taxation as an alternative in the tax code, and as the main source of government revenues, leads to a more efficient tax system. However the conventional wisdom is that the change from the actual tax code, based on taxation of capital and labor income to this consumption based system, has undesirable distributional consequences. In this work a very simple method is developed to argue that the converse is the most reasonable outcome from that fundamental tax reform. The main difference in relation to the literature comes from the assumed source of household heterogeneity. Additionally it is shown that the inclusion of a tax on consumption allows for redistributive policies with no costs in terms of efficiency.

Taxation and Globalization

The decline of capital taxation is associated with efficiency gains. We show that, when agents are heterogeneous, equity concerns can change the policy recommendation driven by efficiency. Given the empirical evidence on the roots of heterogeneity inside each country, either in developing or developed economies, the elimination of capital taxation would lead always to a decline in inequality and to an increase of welfare of the poorest, in a small open economy acting unilaterally. On the contrary for a group of open economies following the same policy, the opposite occurs: with the elimination of capital taxation inequality worsens and it hurts the poorest of each country. Therefore globalization can be important to support a positive tax on capital.

Unique equilibrium with single monetary instrument rules

We consider standard cash-in-advance monetary models and show that there are interest rate or money supply rules such that equilibria are unique. The existence of these single instrument rules depends on whether the economy has an infinite horizon or an arbitrarily large but finite horizon.
