It is widely accepted that the costs of underpricing energy are large, whether in advanced or developing countries. This paper explores how large these costs can be by focussing on the size of the external effects that energy subsidies in particular generate in two important sectors?transport...

The analysis of household energy consumption patterns is critical for evaluating public mechanisms, such as subsidies and social tariffs that aim to provide lower income earners with better access to energy sources. This paper focuses on Mexican households to analyze the relations between their...

This paper investigates the effect of carbon or gasoline taxes on commuting-related CO2 emissions in an urban context. To assess the impact of public transport on the efficiency of the tax, the paper investigates two exogenous scenarios using a dynamic urban model (NEDUM-2D) calibrated for the...

Household air pollution is the second leading cause of disease in Madagascar, where more than 99 percent of households rely on solid biomass, such as charcoal, wood, and crop waste, as the main cooking fuel. Only a limited number of studies have looked at the emissions and health consequences of...

The lack of growth in the Brazilian sugarcane-ethanol complex since the 2008 financial crisis has been blamed on policies: lower mandate, holding gasoline prices below world levels, high fuel taxes, and inadequate fuel tax exemptions for ethanol. This paper develops an empirical model of the...

While notoriously inefficient, fuel subsidies are widespread, and in many cases politically stable. This paper discusses and models various political economy aspects of fuel subsidies, focusing on gasoline and kerosene. Both economic and political are considered to explain differences in...

This paper provides an empirical analysis of economic and political determinants of gasoline and diesel prices for about 200 countries over the period 1991-2010. A range of both political and economic variables are found to systematically influence fuel prices, and in ways that differ...

Armenia meets about 75 percent of its energy needs through imports, with natural gas imports from Russia accounting for about 80 percent of total energy imports and 60 percent of total primary energy supply. Because of high dependence on imported energy, Armenia is vulnerable to external energy...

Economically efficient prices for the passenger transportation system in the Greater Cairo Metropolitan Area would account for broader societal costs of traffic congestion and accidents, and local and global pollution. A $2.20 per gallon gasoline tax (2006 US$) would be economically efficient,...
