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...

The Gini coefficient is based on the sum of pairwise income differences, which can be decomposed into separate sums for individuals. Differences with poorer people represent an individual's advantage, while those with richer people constitute deprivation. Weighting deprivation and advantage...

The cross-country relationship between Covid-19 crude mortality rates and previously measured income inequality and poverty in the pandemic’s first wave is studied, controlling for other underlying factors, in a sample of 141 countries. An older population, fewer hospital beds, lack of...

This paper examines long-term trends in aggregate wealth and inheritance and in their distributions, focusing on developed economies. A key stylized fact is that wealth is less equally distributed than income. Financial assets predominate among the wealthy, while owner-occupied housing is...

Numerical simulation exercises to analyze the impacts of potential changes in non-tariff policies commonly use ad valorem equivalent tariff treatment even though estimated impacts using explicit model representation and ad valorem equivalent treatments will differ. The difficulty for modellers...

This paper discusses a central element in globalization debate little addressed by economists, namely the interactions at global, national, and community levels between globalization and societally based values. Social values refer to wider notions of collective identity: religious values,...

This paper contrasts the modern use of the assumption that rationality guides individual economic behaviour, as reflected in simple models of utility and profit maximization, to literature between 1890 and 1930 which sharply challenged the use of such an assumption, as well as to later...

In this paper we discuss the global negotiations now underway and aimed at achieving new climate change mitigation and other arrangements after 2012 (the end of the Kyoto commitment period). These were initiated in Bali in December 2007 and are scheduled to conclude by the end of 2009 in...

We explore how outcomes of trade policy retaliation (Nash tariff games) are affected when trade simultaneously takes places geographically across countries and through time via financial intermediation. In such models deficits and surpluses in goods trade are endogenously determined, and...
