Hausmann, R., et al., 2020. Emerging Cities as Independent Engines of Growth: The Case of Buenos Aires.Abstract

What does it take for a sub-national unit to become an autonomous engine of growth? This issue is particularly relevant to large cities, as they tend to display larger and more complex know-how agglomerations and may have access to a broader set of policy tools. To approximate an answer to this question, specific to the case of Buenos Aires, Harvard’s Growth Lab engaged in a research project from December 2018 to June 2019, collaborating with the Center for Evidence-based Evaluation of Policies (CEPE) of Universidad Torcuato di Tella, and the Development Unit of the Secretary of Finance of the City of Buenos Aires. Together, we have developed research agenda that seeks to provide inputs for a policy plan aimed at decoupling Buenos Aires’s growth trajectory from the rest of Argentina’s.

Lora, E., 2020. Income Changes after Inter-city Migration.Abstract
Using panel data for workers who change jobs, changes in several labor outcomes after inter-city migration are estimated by comparing workers in similar circumstances who move to a new city –the treatment group—with those who stay in the same city –the control group. After matching the two groups using Mahalanobis distances over a wide range of covariates, the methodology of “difference-in-difference treatment effects on the treated” is used to estimate changes after migration. On average, migrants experience income gains but their dedication to formal employment becomes shorter. Income changes are very heterogenous, with low-wage workers and those formerly employed by small firms experiencing larger and more sustained gains. The propensity to migrate by groups of sex, age, wage level, initial dedication, initial firm size and size of city of origin is significantly and directly correlated with the expected cumulative income gains of migration, and inversely with the uncertainty of such gains.

Levy-Yeyati, E. & Montane, M., 2020. Specificity of Human Capital: An Occupation Space Based on Job-to-Job Transitions.Abstract
Using job transition data from Argentina’s Household Survey, we document the extent to which human capital is specific to occupations and activities. Based on workers’ propensity to move between occupations/industries, we build Occupation and Industry Spaces to illustrate job similarities, and we compute an occupation and industry similarity measures that, in turn, we use to explain wage transition dynamics. We show that our similarity measures influence positively post-transition wages. Inasmuch as wages capture a worker´s marginal productivity and this productivity reflects the degree to which a worker matches the job’s skill demand, our results indicate that a worker´s human capital is specific to both occupation and activity: closer occupations share similar skill demands and task composition (in other words, demand similar workers) and imply a smaller human capital loss in the event of a transition.

Pan, C.I., 2019. Tax Avoidance in Buenos Aires: The Case of Ingresos Brutos.Abstract
This study presents evidence of tax avoidance in Buenos Aires, Argentina. I exploit a break in the tax scheme of the most controversial tax, Ingresos Brutos (gross income), between the city and the greater area, which are otherwise identical law and regulation-wise for the studied population. When possible, workers would rather travel longer distances to their jobs than face the tax burden. Given that this type of avoidance is costly, results suggest that Ingresos Brutos might be acting as a binding constraint to growth for businesses.

Barrios, D. & Santos, M.A., 2019. Is There Life After Ford?. In City Design, Planning & Policy Innovations: The Case of Hermosillo. Inter-American Development Bank, pp. 131-53. Publisher's VersionAbstract

This publication summarizes the outcomes and lessons learned from the Fall 2017 course titled “Emergent Urbanism: Planning and Design Visions for the City of Hermosillo, Mexico” (ADV-9146). Taught by professors Diane Davis and Felipe Vera, this course asked a group of 12 students to design a set of projects that could lay the groundwork for a sustainable future for the city of Hermosillo—an emerging city located in northwest Mexico and the capital of the state of Sonora. Part of a larger initiative funded by the Inter-American Development Bank and the North-American Development Bank in collaboration with Harvard University, ideas developed for this class were the product of collaboration between faculty and students at the Graduate School of Design, the Kennedy School’s Center for International Development and the T.H. Chan School of Public Health.

Written by Miguel Angel Santos and Douglas Barrios—two Growth Lab research fellows—the fourth chapter titled “Is There Life After Ford?” focuses on Hermosillo’s economic competitiveness and, specifically, the reasons behind the city’s economic stagnation. It sees the city’s overreliance on the automobile industry as a primary concern. Based on two methodologies developed at the Growth Lab—the Growth Diagnostic and the Economic Complexity Analysis—this piece proposes alternative pathways for Hermosillo’s future economic growth.

Lora, E., 2019. Empleo Femenino en las Ciudades Colombianas: Un Método de Descripción Estadística.Abstract

Este trabajo propone una metodología de descomposición estadística para describir en
forma coherente las dimensiones del empleo femenino según la estructura del mercado
laboral y según la estructura productiva de las ciudades. La metodología se utiliza
para analizar el empleo femenino “pleno y decente” en 23 ciudades colombianas entre
2008 y 2016. Según la estructura laboral, se encuentra que la brecha de género en el
empleo pleno y decente se debe a diferencias en la participación laboral y en la
formalidad del empleo, más que a diferencias entre hombres y mujeres en el desempleo
o en la dedicación al empleo. Según la estructura productiva, se encuentra que la
orientación por sexo y la composición del empleo sectorial de las ciudades tienen
influencia modesta en las diferencias entre ciudades en la generación de empleo
femenino pleno y decente, ya que éstas resultan sobre todo de las diferencias en la
capacidad de generación de para ambos sexos. La metodología también se usa para
analizar los cambios en el período. Se sugieren posibles extensiones de la metodología
propuesta e implicaciones para futuras investigaciones.

Female Employment in Colombian Cities: A Method of Statistical Description

This paper proposes a methodology of statistical decomposition to describe in a
coherent way the dimensions of female employment according to the structure of the
labor market and according to the productive structure of cities. The methodology is
used to analyze "full and decent" female employment in 23 Colombian cities between
2008 and 2016. According to the labor structure, it is found that the gender gap in full
and decent employment is due to differences in labor participation and in the
formality of employment, rather than differences between men and women in
unemployment or dedication to employment. According to the productive structure, it
is found that the orientation by sex and the composition of sectoral employment in
cities have a modest influence on the differences between cities in the generation of full
and decent female employment, since these are mainly the result of differences in
cities’ capacities to generate employment for both sexes. The methodology is also used
to analyze changes in the period. Potential extensions of the proposed methodology
and implications for future research are suggested.

Lora, E., 2019. Forecasting Formal Employment in Cities.Abstract
Can “full and productive employment for all” be achieved by 2030 as envisaged by the United Nations Sustainable Development Goals? This paper assesses the issue for the largest 62 Colombian cities using social security administrative records between 2008 and 2015, which show that the larger the city, the higher its formal occupation rate. This is explained by the fact that formal employment creation is restricted by the availability of the diverse skills needed in complex sectors. Since skill accumulation is a gradual path-dependent process, future formal employment by city can be forecasted using either ordinary least square regression results or machine learning algorithms. The results show that the share of working population in formal employment will increase between 13 and nearly 32 percent points between 2015 and 2030, which is substantial but still insufficient to achieve the goal. Results are broadly consistent across methods for the larger cities, but not the smaller ones. For these, the machine learning method provides nuanced forecasts which may help further explorations into the relation between complexity and formal employment at the city level.

Gorrín, J., A., J.R.M. & Ricca, B., 2019. The Impact of the Mexican Drug War on Trade.Abstract
This paper studies the unintended economic consequences of increases in violence following the Mexican Drug War. We study the effects on exports in municipalities with different levels of exposure to violence after the policy. A focus on exports allows us to control for demand shocks by comparing exports of the same product to the same country of destination. Building on the close elections identification strategy proposed by Dell (2015), we show that municipalities that are exogenously exposed to the Drug War experience a 40% decrease in export growth on the in- tensive margin. Large exporters suffer larger effects, along with exports of more complex, capital intensive, and skill intensive products. Finally, using firm level data, we provide evidence consistent with violence increasing marginal exporting costs.

Fool’s Gold: On the Impact of Venezuelan Devaluations in Multinational Stock Prices
Bahar, D., Molina, C.A. & Santos, M.A., 2018. Fool’s Gold: On the Impact of Venezuelan Devaluations in Multinational Stock Prices. Economia LACEA , 19 (1) , pp. 93-128. Publisher's VersionAbstract
This paper documents negative cumulative abnormal returns (CARs) to five exchange rate devaluations in Venezuela within the context of stiff exchange controls and large black-market premiums, using daily stock prices for 110 multinational corporations with Venezuelan subsidiaries. The results suggest evidence of statistically and economically significant negative CARs of up to 2.07 percent over the ten-day event window. We find consistent results using synthetic controls to causally infer the effect of each devaluation on the stock prices of global firms active in the country at the time of the event. Our results are at odds with the predictions of the efficient market hypothesis stating that predictable devaluations should not affect the stock prices of large multinational companies on the day of the event, and even less so when they happen in small countries. We interpret these results as a suggestive indication of market inefficiencies in the process of asset pricing.

Hausmann, R., Ganguli, I. & Viarengo, M., 2018. Career dynamics and gender gaps among employees in the microfinance sector. Publisher's VersionAbstract

While microfinance institutions (MFIs) are increasingly important as employers in the developing world, there is little micro-level evidence on gender differences among MFI employees and MFIs’ relation to economic development.

We use a unique panel dataset of employees from Latin America’s largest MFI to show that gender gaps favouring men for promotion exist primarily in the sales division, while there is a significant gender wage gap in the administrative division. Among loan officers in the sales division, the gender gap in promotion and wages reverses.

Finally, female employees tend to work with clients with better loan terms and a history of loans with the institution.

Barrios, D., et al., 2018. Campeche: Diagnóstico Industrial.Abstract

En este estudio se consideraron los productos priorizados en el Reporte de Complejidad Económica de Campeche y se procedió a evaluar su potencial a partir de un conjunto de consideraciones de mercado. Luego, se agregó el potencial de cada producto en distintas colecciones de producto, y se seleccionó una industria cuya estimulación y desarrollo constituya una apuesta de desarrollo prometedora el estado. Respecto de éste se detallaron algunas estadísticas generales como una forma de evaluar su potencial de crecimiento e impacto para la economía local, estatal y nacional.

Para el objeto de este estudio, el sector industrial escogido para el análisis de cuellos de botella fue el de “Textiles” y, más puntualmente, los productos: “Abrigos para mujeres, de punto”, “Calzoncillos para hombres, de punto”, “Camisas para hombres, de punto”, “Camisas para mujeres”, “Camisas para mujeres, de punto” , “Las demás prendas de vestir, de punto”, “Suéteres (jerseys) y artículos similares, de punto”, “Sostenes y artículos similares”, “Trajes para hombres, de punto”, “Trajes para mujeres, de punto”, “Trajes y pantalones para hombres”, “Trajes y pantalones para mujeres” y “Trapos y cordajes textiles en desperdicios”. El desarrollo de esta colección de productos puede representar una oportunidad. Sin embargo, recientemente las exportaciones de estos productos por parte de México han venido perdiendo espacios en el mercado global, siendo el valor de las exportaciones mexicanas de estos productos en la actualidad menos de la mitad de lo que era en 2004.

Barrios, D., et al., 2018. There is a Future after Cars: Economic Growth Analysis for Hermosillo.Abstract

For 30 years, Hermosillo has been wondering whether it has a future after Ford. Until the early 1980s, the city relied mainly on agricultural activity. When the multinational motor company arrived in this northwestern Mexican city in 1986, it changed the history of a region that up until that point had relied heavily on agriculture. The assembly plant was established and many auto parts suppliers sprang up, triggering industrialization and increasing the complexity of its economy, its productivity, and wages. Intensive manufacturing development turned Hermosillo into the fifth richest metropolitan area in Mexico in 1998.

Broadly speaking, this growth trajectory was maintained. In 2015, Hermosillo was in the top 5% of wealthiest municipalities, with poverty levels and informal employment rates significantly lower than in the rest of the country. But the economy of this city in Sonora State has clearly lost its dynamism over the past few years. Even in Mexico’s low-growth context during the period 2005-2015, growth in per capita gross domestic product in Hermosillo (1.3%) fell below the federal average (1.4%). Hermosillo’s relative performance during this decade was not uniform. Between 2005 and 2010, it grew at a rate of 1.3%, placing it in the 66th percentile (among the top 34% for growth rate) of all municipalities in Mexico. In the second half of the decade, Hermosillo barely reached 1.2% growth, falling to the 47th percentile (53% of Mexican municipalities grew more). The situation worsened in the years 2013-2015, when output per worker fell by 7.2%.

What happened in Hermosillo? Can the current economic structure sustain the municipality’s high wages and guarantee future growth? What policy interventions are needed?

Seeking answers to these questions, the Growth Lab at Harvard's Center for International Development joined forces with the Inter-American Development Bank or IDB, in particular with its Emerging and Sustainable Cities Program (ESC). This program is a technical assistance initiative that provides support to regional governments to develop and execute urban sustainability projects. ESC’s goal is to contribute to priority urban interventions to provide the sustainable, harmonious growth of cities. This part of its vision is aligned with the idea of promoting inclusive growth and prosperity that guides the Growth Lab's research.

Hausmann, R., Hinz, J. & Yildirim, M.A., 2018. Measuring Venezuelan Emigration with Twitter.Abstract
Venezuela has seen an unprecedented exodus of people in recent months. In response to a dramatic economic downturn in which inflation is soaring, oil production tanking, and a humanitarian catastrophe unfolding, many Venezuelans are seeking refuge in neighboring countries. However, the lack of official numbers on emigration from the Venezuelan government, and receiving countries largely refusing to acknowledge a refugee status for affected people, it has been difficult to quantify the magnitude of this crisis. In this note we document how we use data from the social media service Twitter to measure the emigration of people from Venezuela. Using a simple statistical model that allows us to correct for a sampling bias in the data, we estimate that up to 2,9 million Venezuelans have left the country in the past year.

Venezuela: Public Debate and the Management of Oil Resources and Revenues
Villasmil, R., 2018. Venezuela: Public Debate and the Management of Oil Resources and Revenues. In Public Brainpower. Palgrave Macmillan, Cham, pp. 347-367. Publisher's VersionAbstract
Although Venezuela’s experience since the 1980s would seem to make it a classic example of the resource curse, that perspective fails to explain the country’s impressive economic, social and institutional performance—including healthy public debate—during the first five decades after oil was first produced on a large scale. This chapter takes a long view of the Venezuelan experience and argues that this initial performance was lengthy and positive but fragile, given the incapacity of the country’s institutions to adapt to the different environment that developed afterwards, characterized by high oil price volatility and significant and sudden declines in oil revenues. The prolonged initial period of equilibrium became a curse of sorts. Lacking adaptive efficiency, political institutions were forced to rely increasingly on maintaining an illusion of harmony, and as faltering performance became evident, Venezuelans began questioning the model and its hegemonic arrangements. The scope and magnitude of the economic, social and institutional devastation that followed were such that public debate became one the first casualties. One of the main problems in contemporary Venezuela is the polarization of politics. This makes it difficult for the country’s population to arrive at reasonable solutions through public discussion.

Ravinutala, S., Gomez-Lievano, A. & Lora, E., 2017. How Industry-Related Capabilities Affect Export Possibilities, Cambridge: Growth Lab at Harvard's Center for International Development.Abstract

The central question we will explore in this document is: Can we anticipate the opportunities that Colombian cities have to export specific products based on their existing productive capabilities?

In the following pages, we report a collection of results, analyses, and advances in which we assess how industry-related capabilities affect export possibilities. Our final goal will be to create a single measure that synthesizes all the knowledge and existing information about the productive capabilities of each city, both “horizontal” and “vertical”, and that quantifies how competitive a city can be if it aims at exporting a given product it does not yet export.

This document is broken in two main efforts: First, we want to understand the “mechanics” of diversification processes. And second, we want to be able to provide recommendations of products that are not produced in cities, but should be. The first effort requires a multitude of analyses, each trying to describe the characteristics of firms, of cities, and of the mechanisms that expand the export baskets of places. The second effort requires the development of a statistical model that is accurate when predicting the appearances of products in cities. These two efforts, explaining and predicting, are complementary, but different.

Explanations that lack the power of accurately predicting the future are useless in practice; predictions of phenomena for which we lack understanding are dangerous. But together they provide a unified story that can inform policy decisions.

What is different about urbanization in rich and poor countries? Cities in Brazil, China, India and the United States
Chauvin, J.P., et al., 2017. What is different about urbanization in rich and poor countries? Cities in Brazil, China, India and the United States. Journal of Urban Economics , 98 (March 2017) , pp. 17-49. Publisher's VersionAbstract
Are the well-known facts about urbanization in the United States also true for the developing world? We compare American metropolitan areas with analogous geographic units in Brazil, China and India. Both Gibrat’s Law and Zipf’s Law seem to hold as well in Brazil as in the U.S., but China and India look quite different. In Brazil and China, the implications of the spatial equilibrium hypothesis, the central organizing idea of urban economics, are not rejected. The India data, however, repeatedly rejects tests inspired by the spatial equilibrium assumption. One hypothesis is that spatial equilibrium only emerges with economic development, as markets replace social relationships and as human capital spreads more widely. In all four countries there is strong evidence of agglomeration economies and human capital externalities. The correlation between density and earnings is stronger in both China and India than in the U.S., strongest in China. In India the gap between urban and rural wages is huge, but the correlation between city size and earnings is more modest. The cross-sectional relationship between area-level skills and both earnings and area-level growth are also stronger in the developing world than in the U.S. The forces that drive urban success seem similar in the rich and poor world, even if limited migration and difficult housing markets make it harder for a spatial equilibrium to develop.
Halff, A., et al., 2017. Apocalypse Now: Venezuela, Oil and Reconstruction, Columbia University's School of International and Public Affairs. Publisher's VersionAbstract

Venezuela is at a breaking point. The political, economic, financial, social and humanitarian crisis that has gripped the country is intensifying. This unsustainable situation raises several urgent questions: Which path will the embattled OPEC country take out of the current turmoil? What type of political transition lies ahead? What short-term and long-term impact will the crisis have on its ailing oil industry, economy and bond debt? What would be the best and most effective prescription for oil and economic recovery under a new governance regime? To discuss these matters, the Center on Global Energy Policy brought together on June 19, 2017 a group of about 45 experts, including oil industry executives, investment bankers, economists and political scientists from leading think tanks and universities, consultants, and multilateral organization representatives. This note provides some of the highlights from that roundtable discussion, which was held under the Chatham House rule.

Patt, A., et al., 2017. International Emigrant Selection on Occupational Skills.Abstract
We present the first evidence that international emigrant selection on education and earnings materializes through occupational skills. Combining novel data from a representative Mexican task survey with rich individual-level worker data, we find that Mexican migrants to the United States have higher manual skills and lower cognitive skills than non-migrants. Conditional on occupational skills, education and earnings no longer predict migration decisions. Differential labor-market returns to occupational skills explain the observed selection pattern and significantly outperform previously used returns-to-skills measures in predicting migration. Results are persistent over time and hold within narrowly defined regional, sectoral, and occupational labor markets.
