The concept of environmental migrants occurs frequently in the policy debate, in particular with regard to climate change and its incidence on low-income countries. This paper reviews the economic studies of environmentally-induced migration. It includes the recent empirical analyses that try to...

Since the 1980s, income inequality in New Zealand has been a growing concern - particularly in metropolitan areas. At the same time, the encouragement of permanent and temporary immigration has led to the foreign-born accounting for a growing share of the population; this is disproportionally so...

We explore the relationship between import protection and the household distribution of income. We first develop a general-equilibrium mapping from tariffs to household inequality measures. This also yields predictions for linkages between tariffs, development level, and observed household...

The inequality dataset compiled in the 1990s by the World Bank and extended by the United Nations has been both widely used and strongly criticized. The criticisms raise questions about conclusions drawn from secondary inequality datasets in general. The authors develop techniques to deal with...

We analyze general equilibrium relationships between trade policy and the household distribution of income, decomposing social welfare into real income level and variance components and emphasizing Gini and Atkinson indexes. We embed these inequality adjusted social welfare functions in a...

We analyze general equilibrium relationships between trade policy and the household distribution of income, decomposing social welfare into real income level and variance components through Gini and Atkinson indexes. We embed these inequality-adjusted social welfare functions in a general...

This study investigates whether the Federal Reserve (Fed) should care about inequality. We develop a Heterogeneous Agent New Keynesian (HANK) model, which generates empirically realistic inequalities and business cycle properties observed in the U.S. data. Households in the model economy are...

The research results on the impact of financial openness on inequality are highly inconsistent. After introducing income share as an indicator of inequality into a theoretical model to replace the typical Gini coefficient, we refute the mainstream conclusion that exogenous variables can explain...

Following Sen's (1973) characterization of the Gini coefficient as a ratio between a measure of aggregate income-based stress ("depression" in Sen's terminology) and aggregate income, we transform the Gini coefficient into a social welfare function rather than having the Gini coefficient feature...
