Many developing countries lack spatially disaggregated price data. Some analysts use "no-price" methods by using a food Engel curve to derive the deflator as that needed for nominally similar households to have equal food shares in all regions and time periods. This method cannot be tested in...

Although several studies have examined why overall price levels are higher in richer countries, little is known about whether there is a similar relationship at the urban and city level across countries. This paper compares the price levels of cities in Sub-Saharan Africa with those of other...

This paper provides an overview of the impact of once-and-for-all changes in commodity prices and other prices on household welfare. It begins with a collection of stylized facts related to commodities based on household survey data from Latin America and Africa. The data uncover strong...

Tobacco taxes are deemed regressive, because the poorest families tend to allocate larger shares of their budget to purchase tobacco. However, as taxes also discourage tobacco use, some of the most adverse effects, including higher medical expenses, lower life expectancy at birth, added years of...

Despite the well-known positive effects of tobacco taxes on health outcomes, policy makers avoid relying on such taxes because of their possible regressive impact. Using an extended cost-benefit analysis to estimate the distributional effect of cigarettes in the Russian Federation, this paper...

This paper exploits unique features of a recently introduced tariff schedule for natural gas in Buenos Aires to estimate the short-run impact of price shocks on residential energy utilization. The schedule induces a nonlinear and non-monotonic relationship between households' accumulated...

Recent volatility in international energy prices has revealed South Eastern Europe as one of the most vulnerable regions to such external shocks. Under the current global economic downturn, in addition, the region?s energy-intensive industries are faced with the challenge of the weakening demand...
