In this paper, the authors describe South Africa's value added tax (VAT), showing that (1) the VAT is mildly regressive, and (2) it is an effective source of government revenue, compared with other tax instruments in South Africa. They evaluate the VAT in the context of other distortions in the...

Indonesia experienced rapid growth and the expansion of the formal financial sector during the last quarter of the 20th century. Although this tendency was reversed by the shock of the financial crisis that spread throughout Asia in 1997 and 1998, macroeconomic stability has since then been...

In this paper, the authors use a highly disaggregate general equilibrium model to analyze the feasibility of a wage subsidy to unskilled workers in South Africa, isolating and estimating its potential employment effects and fiscal cost. They capture the structural characteristics of the labor...

Noting that South Africa may be one of the few African countries that could contribute to mitigating climate change, the authors explore the impact of a carbon tax relative to alternative energy taxes on economic welfare. Using a disaggregate general-equilibrium model of the South African...

This paper examines spending plans suggested by the recent literature regarding Dutch disease and examines their implications to Niger relative to its expanding mineral sector. The key to the benefits of significant mineral revenue lies with the productivity and supply responses of spending. If...

If trade tensions between the United States and certain trading partners escalate into a full-blown trade war, what should developing countries do? Using a global, general-equilibrium model, this paper first simulates the effects of an increase in U.S. tariffs on imports from all regions to...

Armington's insight that imports and domestically produced goods were imperfect substitutes has unleashed extensive estimates of the associated trade elasticity, primarily for developed countries. This notion of product differentiation, which extends symmetrically to exports and domestic goods,...

This paper develops a dynamic, stochastic, general-equilibrium model to analyze and derive simple budget rules in the face of volatile public revenue from natural resources in a low-income country like Niger. The simulation results suggest three policy lessons or rules of thumb. When a resource...

Devarajan, Go, Page, Robinson, and Thierfelder argued that if aid is about the future and recipients are able to plan consumption and investment decisions optimally over time, then the potential problem of an aid-induced appreciation of the real exchange rate (Dutch disease) does not occur. In...

As crude oil prices reach new highs, there is renewed concern about how external shocks will affect growth and poverty in developing countries. This paper describes a macro-micro framework for examining the structural and distributional consequences of a significant external shock-an increase in...
