We study the effect of spatial inequality on economic activity. Given that the relationship is highly simultaneous in nature, we use exogenous variation in geographic features to construct an instrument for spatial inequality, which is independent from any man-made factors. Inequality measures...

This paper considers a partitioned population and develops a decomposition of the Gini index in two components, which measure the within and the between groups inequality. Differently from the most widespread inequality measure decompositions, having a between component that compares the means...

The socioeconomic impact of spatial concentration has been receiving an increasing attention during the last two decades. Consequently, the necessity of effective measures of this phenomenon has increased too. This paper considers a population partitioned by subgroups and develops a...

This paper studies the influence of interregional inequality within countries on internal con-flicts. Regional inequalities are measured by the population-weighted coefficient of variation of regional GDP per capita. As the main innovation, I use a panel data set of country-level re- gional...

Concerns are mounting over the potential for weak future growth as the Korean economy faces a wide range of structural issues including an aging society, a crisis in key regional industries, and the COVID-19 pandemic. Due to these concerns, the Korean government has established innovation growth...

Regional productivity differences provide scope for productivity-enhancing labor mobility. Redistribution reduces relocation incentives through higher taxes or lower transfers. Combining an intensive labor supply margin with an extensive, productivity-enhancing migration margin, we determine how...

Regional productivity differences are large and provide scope for productivity-enhancing inter-regional labor mobility. Using an optimal taxation framework that combines an intensive labor supply margin with an extensive, productivity- enhancing migration margin, we explore the implications of...

Do labor mobility, and co-worker networks contribute to convergence or divergence between regions? Based on the previous literature, labor mobility contributes to knowledge transfer between firms. Therefore, mobility may contribute to decreasing productivity differences, while limited mobility...

Spatial wage differences other incentives to change the location of work either by commuting or by moving to the new work location. Combining an intensive labor supply margin with an extensive, productivity-enhancing margin of work place change due to commuting or moving, I study how spatial...
