Inflation causes high taxation -although real income does not increase- because the tax base targets nominal income. This situation results in as if ability to pay has increased, although it not. Compensation for this deflecting effect of inflation tariff requires growing segments included at rate regularly experienced yearly. However, current need public revenue can cause governments make regu...

Due to the use of distortionary taxation, many believe that real-world economies should attain a lower level of public expenditures than one might suspect from the analysis of arti cial models where lump-sum taxes are assumed to be available. The paper examines this popular hypothesis by means of the two-type self-selection model of income taxation. I provide su cient conditions for both a lowe...

The chronic government deficit (fiscal deficit) and increase in the price level (inflation) have become major concerns for economists policymakers. While numerous studies examined twin problems of fiscal inflation both developed developing economies, their results are inconclusive due to different estimation techniques, chosen time periods, selection variables, etc. Therefore, we deficit-inflat...

In brane inflationary scenarios, the cosmological perturbations are supposed to originate from the vacuum fluctuations of the inflaton field corresponding to the position of the brane. We show that a significant, and possibly dominant, contribution to the curvature perturbation is generated at the end of inflation through the vacuum fluctuations of fields, other than the inflaton, which are lig...

The issue addressed in this paper is the optimal taxation of incomes earned tn the home economy, and of incomes earned abroad, when people can migrate. As a preliminary, the optimal taxation of home incomes when there is migration and no taxation of foreign incomes, is discussed. Then in a more general setting, we deal with optimal taxation of different kinds of labour when another kind of labo...
