We present theory and evidence to suggest that, in the context of analyzing global poverty, the EKS approach to estimating purchasing power parities yields more appropriate international comparison of real incomes than the Geary-Khamis approach. Our analysis of the 1996 and 2005 International...

Questionnaires exploring the relativist vs absolutist perception of wellbeing are administered to 3883 students in eight different countries, four low-income countries (Bolivia, Brazil, Kenya and Laos, 1924 respondents) and four high-income countries (Italy, Sweden, Switzerland and the UK, 1959...

The Millennium Declaration set 2015 as the target date for halving the number of people living in extreme poverty. Exceptional progress in some developing countries makes achieving that goal globally a realistic possibility. However, many countries will fall far short, and up to 1 billion people...

Responsible for 20 million severe injuries and/or deaths annually, few epidemics receive less attention than traffic accidents. Going beyond confirming an inverted U-shaped relationship between mean income and fatalities, we show theoretically that income inequality can positively affect...

La Déclaration du millénaire fixe à 2015 la date butoir pour la réalisation de l’objectif visant à réduire de moitié le nombre de personnes qui vivent dans l’extrême pauvreté. Compte tenu des résultats exceptionnels obtenus dans certains pays en développement, la possibilité...

We use a power-to-resist game to find out the effects of individuals’ judgments about a proposer's selection procedure on the willingness to offer resistance to proposed outcomes. In the experiment, one individual is selected based on a particular procedure. This individual is allowed to...

How should a policy-maker prioritize interventions to improve the public infrastructure with which firms operate and how large are the benefits from doing so likely to be? To address these questions we use survey data on the obstacles arising from poor quality public inputs that managers face in...

We use data from over 20,000 firms in 60 countries to identify constraints on the growth of firms. We interpret managers’ answers to survey questions on the extent to which various aspects of their external environment inhibit the performance of their firm as measuring the shadow cost of...

I discuss the measurement of world poverty and inequality, with particular attention to the role of purchasing power parity (PPP) price indexes from the International Comparison Project. Global inequality increased with the latest revision of the ICP, and this reduced the global poverty line...

Two decades of tax system reforms in the Central Asian Republics (CARs) show that, in addition to political commitment, understanding reformers’ incentive structure and a roadmap are necessary if full reform equilibrium is to be reached. Borrowed laws and institutions that are based on...
