We use analytical and numerical models to explain and quantify the welfare effects of subsidies for artemisinin combination treatments (ACTs), a valuable new class of antimalarial drugs. There are two (second-best) efficiency rationales for such subsidies: by expanding drug use, they reduce...

This paper develops and implements an analytical framework for estimating the optimal levels and welfare effects of alcohol taxes and drunk-driver penalties, accounting for externalities and how policies interact with the broader fiscal system. We find that the fiscal component of the optimal...

This paper provides a first attempt to estimate the cross-price elasticity between alcoholic beverages and leisure, which is critical for assessing how much alcohol taxation might be warranted on fiscal grounds. We estimate an Almost Ideal Demand System defined over alcohol, leisure, and other...
