Davies et al. (2008, 2011) provided the first estimates of the global distribution of wealth, using 2000 as the benchmark year. These estimates have been revised and updated since 2010, and the purpose of this paper is to explain the ways in which the estimation methodology has evolved and...

This paper examines the impacts of a wide range of tax provisions on the incentive to invest in human capital, and shows how these effects can be quantified using effective tax rates, or ETRs. For individuals with median earnings, ETRs on the human capital formed in first-degree university study...

Coastal cities around the world have experienced large costs from major flooding events in recent years. Climate change is predicted to bring an increased likelihood of flooding due to sea level rise and a higher frequency of severe storms. In order to plan future development and adaptation,...

There is a gap in estimates of the personal distribution of wealth in Canada between 1902 and 1970. That gap is partly filled here, using estate multiplier estimates for 1946-1970 and survey results for 1970-2012. Estate multiplier estimates are adjusted for differential mortality, and the...

This paper is the first to compare global trends in income and wealth inequality this century. It is based on large income and wealth microdata samples designed to be representative of all countries in the world. Measured by the Gini coefficient, inequality between countries accounts for about...
