Pakistan, like many LDCs, derives most of government revenue from indirect taxation. However, the system of taxes and subsidies has grown up piecemeal over the years, and it is unlikely that it cannot be improved. Any tax reform proposal must deal with the basic issues of equity and efficiency. Changes in taxes benefit or hurt people according to their demand and supply patterns, while the effe...

The substantial subsidizing of energy prices over the years has led to high energy consumption, inefficiencies, fiscal pressures, and environmental problems in Iran. To address the increasing socio-economic problems associated with the energy subsidies, the government embarked on an aggressive energy price reform through which energy subsidies were removed and cash handouts were given to all ho...

It is suggested that instead of attempting to adjust the consumer price index (CPI) after tax reform it is better to measure changes in after-tax income.

We investigate the effects of political activity on pharmaceutical prices, focusing on the health care reform period in the early 1990s.We characterize firms based on their vulnerability to future price regulation and find that the more vulnerable firms were more likely to take various actions to forestall regulation, most notably coordinating on a specific percentage price increase during 1993...

This paper estimates a model of residential electricity demand to project the impact of proposed tariff changes on a representative sample of 130 Barbadian households. The results from the demand function suggest that the price elasticities of demand for particular appliances varied significantly, with households that utilize solar water heating being more price elastic than households that use...

We study Pareto improvements whose implementation requires knowledge of only market prices and traded quantities, not utility and demand functions. Quantity stabilizations (for example, the Lau, Qian, and Roland model of dual-track reform) give agents the right to repeat their earlier trades and hence require policymakers to know the quantities agents previously exchanged. While reasonable in s...

This study exploits a natural experiment in Belgium to estimate the effect of copayment increases on the demand for physician services. It shows how a differences-in-differences (DD) estimator of the price effects can be decomposed into effects induced by the common average proportional price increase (income effects) and by the change in relative prices (substitution effects). The price elasti...
