Since 2008, when Colombia ratified the Framework Convention for Tobacco Control, available evidence of the impact of tobacco consumption, its health effects, and low tax revenues resulting from low tobacco taxation and prices had grown. By 2015, Colombia's cigarette prices stood higher than only one other country in the region, and smoking had become the second leading modifiable risk factor for premature mortality. At that time, reduced fiscal revenues resulting from a sharp drop in oil prices, accompanied by growing demand for government spending arising partly from a change in legislation that increased health benefits for the lower socioeconomic population, led to a call for tax reform. The preparation of the document was accompanied by technical training, studies, and public fora with national and international experts, civil society, and academia presenting evidences and arguing for increased taxation to lead to a reduction in tobacco consumption and, in the future, a reduction in costs to the health system. The fora and open dialogue helped align strategies of the Ministry of Health and Social Protection, and the Ministry of Finance in presenting the reform to Congress for approval with a larger academic and civil society support for this measure. In December 2016, resulting from the above-mentioned efforts, Colombia passed a major tax increase on tobacco products with the goal of decreasing smoking and improving population health. While tobacco taxes are known to be highly effective in reducing the prevalence of smoking, they are often criticized as being regressive in consumption. This analysis attempts to assess the distributional impact (across income quintiles) of the new tax on selected health and financial outcomes.

The paper assesses the impact of overall inequality, as well as inequality among the poor and among the rich, on the growth rates along various percentiles of the income distribution. The analysis uses micro-census data from U.S. states covering the period from 1960 to 2010. The paper finds evidence that high levels of inequality reduce the income growth of the poor and, if anything, help the growth of the rich. When inequality is deconstructed into bottom and top inequality, the analysis finds that it is mostly top inequality that is holding back growth at the bottom.

Household income surveys often fail to capture top incomes which leads to an underestimation of income inequality. A popular solution is to combine the household survey with data from income tax records, which has been found to result in significant upward corrections of inequality estimates. Unfortunately, tax records are unavailable in many countries, including most of the developing world. In the absence of data from tax records, this study explores the feasibility of using data on house prices to estimate the top tail of the income distribution. In an application to Egypt, where estimates of inequality based on household surveys alone are low by international standards, the study finds strong evidence that inequality is indeed being underestimated by a considerable margin. The Gini index for urban Egypt is found to increase from 36 to 47 after correcting for the missing top tail.

Income differences arise from many sources. While some kinds of inequality, caused by effort differences, might be associated with faster economic growth, other kinds, arising from unequal opportunities for investment, might be detrimental to economic progress. This study uses two new metadata sets, consisting of 118 household surveys and 134 Demographic and Health Surveys, to revisit the question of whether inequality is associated with economic growth and, in particular, to examine whether inequality of opportunity-driven by circumstances at birth-has a negative effect on subsequent growth. The results are suggestive but not robust: while overall income inequality is generally negatively associated with growth in the household survey sample, we find no evidence that this is due to the component associated with unequal opportunities. In the Demographic and Health Surveys sample, both overall wealth inequality and inequality of opportunity have a negative effect on growth in some of the preferred specifications, but the results are not robust to relatively minor changes. On balance, although the results are suggestive of a negative association between inequality and growth, the data do not permit robust conclusions as to whether inequality of opportunity is bad for growth.

Building on earlier work by political philosophers, economists have recently sought to define a concept of equity that accommodates the fairness of reward to individual responsibility and effort, while allowing for the existence of some inequalities which are unfair and should be compensated. This paper-commissioned as a chapter for the Oxford Handbook of Well Being and Public Policy-provides a critical review of the economic literature on equality and inequality of opportunity. A simple 'canonical model' of equal opportunity is proposed, and used to explore the two fundamental concepts in this (relatively) new theory of social justice: the principles of compensation and reward. Ex-ante and ex-post versions of the compensation principle are presented, and the tensions between them are discussed. Different approaches to the measurement of inequality of opportunity-and empirical applications-are reviewed, and implications for the measurement of poverty and of the rate of economic development are discussed.
