The objective of this paper is to study optimal …scal and monetary policy in a dynamic Mirrlees model where the frictions giving rise to money as a medium of exchange are explicitly modeled. The framework is a three period OLG model where agents are born every other period. The young and old trade in perfectly competitive centralized markets. In ‘middle age’, agents receive preference shocks an...

A windfall of natural resource revenue (or foreign aid) faces government with choices of how to manage public debt, investment, and the distribution of funds for consumption, particularly if the windfall is both anticipated and temporary. We show that the permanent income hypothesis prescription of an ever-lasting increase in consumption financed by borrowing ahead of the windfall and then accu...

Abstract T he return of capital is fundamental to the intertemporal allocation of resources by changing the consumption behavior and capital accumulation over time. Taxation on return of capital increases the marginal product of capital, meaning that capital stock is lower than when capital is not taxed, which results decreased growth and welfare in steady state. This pape...

In this paper, I study the properties of the Ramsey equilibrium in a model with distortionary taxation, nominal non-state-contingent debt, and costs of surprise inßation. To do this, I modify the standard cash-credit good economy studied in the optimal policy literature to include sticky prices. With this modiÞcation, the Ramsey planner must balance the shock absorbing beneÞts of surprise inßat...

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...

In an earlier paper, titled Non-linear effects of tax changes on output: The role the initial level taxation, we estimated multipliers using (i) a novel dataset value-added taxes for 51 countries (21 industrial and 30 developing) period 1970-2014, (ii) so-called narrative approach developed by Romer (2010) to properly identify exogenous changes. main finding is that, in line with existing theor...

BACKGROUND Diabetes is a costly and debilitating disease. The aim of the study is to quantify the individual and national costs of diabetes resulting from people retiring early because of this disease, including lost income; lost income taxation, increased government welfare payments; and reductions in GDP. METHODS A purpose-built microsimulation model, Health&WealthMOD2030, was used to estim...
