Robert Allen’s recent AER paper on “Absolute Poverty: When Necessity Displaces Desire” is a fascinating read, on many levels. The paper uses linear programming (LP) to compute (four variants of) least-cost diets for twenty countries, using prices from the International Comparisons Project (ICP) microdata. To the resulting least-cost food budgets, estimates of non-food costs covering housing, fuel, lighting, clothing and soap are added, generating “basic need poverty lines” (BNPL) for each country.

Sir Anthony Atkinson, who was Centennial Professor at the London School of Economics and Fellow of Nuffield College at Oxford, passed away on New Year’s Day, at the age of 72. Tony was a highly distinguished economist: He was a Fellow of the British Academy and a past president of the Econometric Society, the European Economic Association, the International Economic Association and the Royal Economic Society. He was also an exceedingly decent, kind and generous man.
Although his contributions to economics are wide-ranging, his main field was Public Economics. He was an editor of the Journal of Public Economics for 25 years, and his textbook “Lectures on Public Economics”, co-authored with Joe Stiglitz in 1980, remains a key reference for graduate students to this day. Within the broad field of public economics, Tony published path-breaking work on the measurement, causes and consequences of poverty and inequality – from his early work on Lorenz dominance in 1970, all the way to his more recent joint work with Piketty, Saez and others on the study of top incomes. Over his 50-year academic career, he taught, supervised and examined a large number of PhD students, some of whom came to work at the World Bank at some point in their careers.
