Shortly before the 2011 Libyan revolution, consumers'subsidies were rapidly increased by the regime in an effort to reduce social discontent. In the aftermath of the revolution, these subsidies became important for people's subsistence, but also a very heavy burden for the state budget. Since...

The cost of the subsidy system in Morocco peaked at 6.6 percent of gross domestic product (GDP) in 2012, an amount larger than the country’s total investment budget for that year. Direct subsidies to households in 2013 (October 2013 prices) are estimated at DH34.4 billion (US$4.1 billion, or...

The paper provides basic guidelines and tools for simulating subsidy reforms with Stata using a single cross-section survey. Simulations are discussed under a partial equilibrium and medium-term framework using a marginal approach. The paper distinguishes between single priced products, such as...

Income mobility is often thought to equalize permanent incomes and thereby to improve social welfare. The welfare analysis of mobility often fails, however, to account for the cost of the variability of periodic incomes around permanent incomes. This paper assesses the net welfare benefit of...

We investigate the properties of a family of social evaluation functions and inequality indices which merge the features of the family of Atkinson (1970) and S-Gini (Donaldson and Weymark (1980, 1983), Yitzhaki (1983) and Kakwani (1980)) indices. Income inequality aversion is captured by...

This study assesses the incidence of pollution control policies on households. In contrast to previous studies, we employ an integrated framework combining a multisector general equilibrium model with a stochastic dominance analysis using household-leved data. We consider three policy...

This paper explores the link between poverty and inequality through an analysis of the poverty impact of changes in income-component inequality and in between -an within- group inequality. This can help shed light on the theoretical and empirical linkages between poverty, growth and inequality....

The social performance of fiscal redistributive mechanisms in Canada continues to receive a growing interest from politicians and research scientists. The aim of this paper is to assess the evolution of social classes in Canada and to check whether the market and governmental redistribution...

This paper explores the link between polarization and inequality and proposes some analytical methods to decompose the Duclos, Esteban, and Ray (2004) polarization index by population groups or income sources. In some cases, the decomposition methods were extend to the Esteban and Ray (1994)...

This paper proposes techniques to test whether growth has been pro-poor. We first review different definitions of pro-poorness and argue for the use of methods that can generate results that are robust over classes of pro-poor measures and ranges of poverty lines. We then provide statistical...
