This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network-representing 20-33% of the frontier knowledge...

This paper develops a gravity model framework to estimate the impact of infectious diseases on bilateral tourism flows among 38,184 pairs of countries over the period 1995-2017. The results confirm that international tourism is adversely affected by disease risk, and the magnitude of this...

The paper examines the evolution and drivers of labor force participation in European regions, focusing on the effects of trade and technology. As in the United States, rural regions within European countries saw more pronounced declines (or smaller increases) in participation than urban...

The United States stands out among advanced economies with marked declines in labor force participation. National averages furthermore conceal considerable within-country heterogeneity. This paper explores regional differences to shed light on drivers of participation rates at the state and...

Growing regional inequality within countries has raised the perception that 'someplaces and people' are left behind. This has prompted a shift toward inward-looking policies andaway from pro-growth reforms. This paper presents novel stylized facts on regional inequality forOECD countries. It...

This paper uses an augmented gravity model framework to investigate the historical impact of infectious diseases on international tourism and develops an out-of-sample prediction model. Using bilateral tourism flows among 38,184 pairs of countries during the period 1995–2017, I compare the...

This paper presents a novel framework to estimate the elasticity between nighttime lights and quarterly economic activity. The relationship is identified by accounting for varying degrees of measurement errors in nighttime light data across countries. The estimated elasticity is 1.55 for...

We discuss regional disparities in economic performance and living standards. We first set out some key facts, and provide a conceptual framework to help analyze whether such disparities are efficient, or instead reflect market and/or policy failures. We examine whether policy attempts to reduce...

Past studies on the relationship between electricity consumption and temperature have primarily focused on individual countries. Many regions are understudied as a result of data constraint. This paper studies the relationship on a global scale, overcoming the data constraint by using grid-level...
