Cities of Workers, Children or Seniors? Age Structure and Economic Growth in a Global Cross-Section of Cities

August 2019

Remi Jedwab, Daniel Pereira, and Mark Roberts

IIEP working paper 2019-13

Abstract: A large literature documents the positive influence of a city’s skill structure on its rate of economic growth. By contrast, the effect of a city’s age structure on its economic growth has been a hitherto largely neglected area of research. We hypothesize that cities with more working-age adults are likely to grow faster than cities with more children or seniors and set out the potential channels through which such differential growth may occur. Using data from a variety of historical and contemporary sources, we show that there exists marked variation in the age structure of the world’s largest cities, both across cities and over time. We then study how age structure affects economic growth for a global cross-section of mega-cities. Using various identification strategies, we find that mega-cities with higher dependency ratios – i.e. with more children and/or seniors per working-age adult – grow significantly slower. Such effects are particularly pronounced for cities with high shares of children. This result appears to be mainly driven by the direct negative effects of a higher dependency ratio on the size of the working-age population and the indirect effects on work hours and productivity for working age adults within a city.

Divorce among European and Mexican Immigrants in the U.S

August 2019

Barry Chiswick and Christina Houseworth

IIEP working paper 2019-12

Abstract: This paper analyzes the status of being currently divorced among European and Mexican immigrants in the U.S., among themselves and in comparison to the native born of the same ancestries. The data are for males and females age 18 to 55, who married only once, in the 2010-2014 American Community Surveys.

Among immigrants, better job opportunities, measured by educational attainment, English proficiency and a longer duration in the U.S. are associated with a higher probability of being divorced. Those who married prior to migration and who first married at an older age are less likely to be divorced. Those who live in states with a higher divorce rate are more likely to be divorced. Thus, currently being divorced among immigrants is more likely for those who are better positioned in the labor market, less closely connected to their ethnic origins, and among Mexican immigrants who live in an environment in which divorce is more prevalent.

South Africa: Rebuilding the Dream

Monday, November 11th, 2019

Event Overview

Twenty-five years after the end of apartheid, South Africa’s economy is in crisis. Inequality in South Africa is the highest in the world; unemployment is on the rise; and economic growth (projected at 0.8 percent in 2019) has hovered precariously close to recession. In After Dawn: Hope After State Captureformer South African Deputy Finance Minister Mcebisi Jonas, the man who first blew the whistle on corruption in the Zuma administration, offers a blunt assessment of the country’s economic woes and the failures of governance that caused it. He proposes a series of practical solutions to build a growing, job-creating economy that can begin to meet South African’s unfulfilled expectations of economic transformation.

The Venezuelan Migration Crisis: its Human and Economic Faces

Wednesday, November 13, 2019
5:30 p.m.- 7:00 p.m.* 
Linder Family Commons, Room 602
Elliot School of International Affairs
1957 E St NW, Washington, DC 20052

With a repressive regime and a collapsing economy driving millions of people out of Venezuela, the hemisphere is faced with the ramifications of this massive exodus. The tragic impact on the lives of Venezuelans living as refugees and migrants combined with the economic costs for the receiving countries makes this a crisis that is screaming for greater attention. This panel will examine these two different, yet overlapping, components by looking at the economic and human faces of this migration crisis. This discussion will be led by the following speakers:
 
Moderator/Commentator: Marie Price, Professor of Geography and International Affairs, George Washington University (GWU)
Oscar Valencia, Lead Specialist at the Fiscal Management Division of the Inter-American Development Bank (IADB)
Francisco Quintana, Director of the Venezuelan Human Mobility Program and the Andean, North-American and Caribbean Region of the Center for Justice and International Law (CEJIL)

This event is co-sponosored by the Latin American & Hemispheric Studies Program (LAHSP), the Institute for International Economic Policy (IIEP at GWU), the International Development Studies Program (IDS), and LATAM@GW.

How Should We Measure City Size? Theory and Evidence Within and Across Rich and Poor Countries

August 2019

Remi Jedwab, Prakash Loungani, and Anthony Yezer

IIEP working paper 2019-11

Abstract: It is obvious that holding city population constant, differences in cities across the world are enormous. Urban giants in poor countries are not large using measures such as land area, interior space or value of output. These differences are easily reconciled mathematically as population is the product of land area, structure space per unit land (i.e., heights), and population per unit interior space (i.e., crowding). The first two are far larger in the cities of developed countries while the latter is larger for the cities of developing countries. In order to study sources of diversity among cities with similar population, we construct a version of the standard urban model (SUM) that yields the prediction that the elasticity of city size with respect to income could be similar within both developing countries and developed countries. However, differences in income and urban technology can explain the physical differences between the cities of developed countries and developing countries. Second, using a variety of newly merged data sets, the predictions of the SUM for similarities and differences of cities in developed and developing countries are tested. The findings suggest that population is a sufficient statistic to characterize city differences among cities within the same country, not across countries.
