In this paper, we 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 to other tax instruments in South Africa. We evaluate the VAT in the context of other distortions in the economy by...

Slowing global warming requires countries to reduce carbon emissions, which imposes costs on their economies. To be effective, most countries must agree collectively to participate (e.g., the Paris Agreement, COP26). However, every country has an incentive not to comply and still reap the...

We surveyed the empirical literature using multi-country computable general equilibrium (CGE) models to analyse potential and actual regional trade agreements (RTAs). The studies indicate that these RTAs improve welfare, that trade creation greatly exceeds trade diversion, and that they are...

In this paper, we use a highly disaggregate general equilibrium model to analyse the feasibility of a wage subsidy to unskilled workers in South Africa, isolating and estimating its potential employment effects and fiscal cost. We capture the structural characteristics of the labour market with...
