Martin, D.A., 2024. Women Seeking Jobs with Limited Information: Evidence from Iraq.Abstract

Do women apply more for jobs when they know the hiring probability of female job seekers directly from employers? I implemented a randomized control trial and a double-incentivized resume rating to elicit the preferences of employers and job seekers for candidates and vacancies in Iraq. The treatment reveals the job offer rate for women, calculated using the employers’ selection of women divided by the total number of female candidates. After revealing the treatment, the women applied for jobs by three more percentage points than the men in the control group. This paper highlights the value of revealing employers’ preferences to improve the match between female candidates and employers when women underestimate the chances of finding a job. 

Nedelkoska, L., et al., 2023. Eight Decades of Changes in Occupational Tasks, Computerization and the Gender Pay Gap.Abstract
We build a new longitudinal dataset of job tasks and technologies by transforming the U.S. Dictionary of Occupational Titles (DOT, 1939 -1991) and four books documenting occupational use of tools and technologies in the 1940s, into a database akin to, and comparable with its digital successor, the O*NET (1998 -today). After creating a single occupational classification stretching between 1939 and 2019, we connect all DOT waves and the decennial O*NET databases into a single dataset, and we connect these with the U.S. Decennial Census data at the level of 585 occupational groups. We use the new dataset to study how technology changed the gender pay gap in the United States since the 1940s. We find that computerization had two counteracting effects on the pay gap -it simultaneously reduced it by attracting more women into better-paying occupations, and increased it through higher returns to computer use among men. The first effect closed the pay gap by 3.3 pp, but the second increased it by 5.8 pp, leading to a net widening of the pay gap.
The impact of return migration on employment and wages in Mexican cities
Diodato, D., Hausmann, R. & Neffke, F., 2023. The impact of return migration on employment and wages in Mexican cities. Journal of Urban Economics , 135 (May). Publisher's VersionAbstract
How does return migration from the US to Mexico affect local workers? Return migrants increase the local labor supply, potentially hurting local workers. However, having been exposed to a more advanced U.S. economy, they may also carry human capital that benefits non-migrants. Using an instrument based on involuntary return migration, we find that, whereas workers who share returnees’ occupations experience a fall in wages, workers in other occupations see their wages rise. These effects are, however, transitory and restricted to the city-industry receiving the returnees. In contrast, returnees permanently alter a city’s long-run industrial composition, by raising employment levels in the local industries that hire them.
Santos, M.A. & Hani, F., 2021. Diagnosing Human Capital as a Binding Constraint to Growth: Tests, Symptoms and Prescriptions.Abstract
The empirical literature on the contributions of human capital investments to economic growth shows mixed results. While evidence from OECD countries demonstrates that human capital accumulation is associated with growth accelerations, the substantial efforts of developing countries to improve access to and quality of education, as a means for skill accumulation, did not translate into higher income per capita. In this paper, we propose a framework, building on the principles of Growth Diagnostics (Hausmann, Rodrik and Velasco, 2008), to enable practitioners to determine whether human capital investments are a priority for a country’s growth strategy. We then discuss and exemplify different tests to diagnose human capital in a place, drawing on the Harvard Growth Lab’s experience in different development context, and discuss various policy options to address skill shortages.
Innovation on Wings: Nonstop Flights and Firm Innovation in the Global Context
Bahar, D., et al., 2023. Innovation on Wings: Nonstop Flights and Firm Innovation in the Global Context. Management Science. Publisher's VersionAbstract

We study whether, when, and how better connectivity through nonstop flights leads to positive innovation outcomes for firms in the global context. Using unique data of all flights emanating from 5,015 airports around the globe from 2005 to 2015 and exploiting a regression discontinuity framework, we report that a 10% increase in nonstop flights between two locations leads to a 3.4% increase in citations and a 1.4% increase in the production of collaborative patents between those locations. This effect is driven primarily by firms as opposed to academic institutions. We further study the characteristics of firms and firm locations that are salient to the relation between nonstop flights and innovation outcomes across countries. Using a gravity model, we posit and find that the positive effect of nonstop flights on innovation is stronger for firms and subsidiaries with greater innovation mass (e.g., stocks of inventors and R&D spending), located in innovation hubs or countries that are deemed technology leaders, and that are separated by large cultural or temporal distance.

Research Summary: The Role of Nonstop Flights in Fostering Global Firm Innovation

Langer, C. & Wiederhold, S., 2023. The Value of Early-Career Skills.Abstract
We develop novel measures of early-career skills that are more detailed, comprehensive, and labor-market-relevant than existing skill proxies. We exploit that skill requirements of apprenticeships in Germany are codified in state-approved, nationally standardized apprenticeship plans. These plans provide more than 13,000 different skills and the exact duration of learning each skill. Following workers over their careers in administrative data, we find that cognitive, social, and digital skills acquired during apprenticeship are highly – yet differently – rewarded. We also document rising returns to digital and social skills since the 1990s, with a more moderate increase in returns to cognitive skills.
Fortunato, A., 2022. Getting Back on the Curve: South Africa’s Manufacturing Challenge.Abstract

The report aims to inform the government’s strategic approach towards manufacturing by analyzing the potential and limits for job creation within the sector. To meet that goal, we analyze the sector’s main features and recent trajectory through the lens of global deindustrialization and South Africa’s particular industrial dynamics. Secondly, we provide evidence of how, when, and why South Africa has deviated from the global deindustrialization trends. Lastly, we provide a policy framework to address the bottlenecks that are preventing South Africa from getting back on a better track of industrial performance.

Shah, K., 2022. Diagnosing South Africa’s High Unemployment and Low Informality.Abstract

This report analyzes the causes and consequences of South Africa’s high rates of unemployment and the unique nature of labor market exclusion in the country. It leverages a combination of new quantitative analysis using South African datasets and international datasets for benchmarking, together with synthesis of existing literature and case studies. The goal is to: (1) characterize the challenge of labor market exclusion in South Africa, (2) identify ways in which this is similar and different to other countries, (3) understand what drives the unique challenges of the labor market in South Africa, and (4) narrow down what policy areas are most important to address the underlying drivers. This report takes a diagnostic approach to understand the causes of South Africa’s unique pattern of low informality.

Hausmann, R. & Bustos, S., 2021. New Avenues for Colombia’s Internationalization: Trade in Tasks.Abstract

One of the consequences of COVID-19 is the recognition that many tasks can be done from home. But anything that can done remotely, can be done from abroad.

Given large salary differences between white collar workers across countries, it would make sense for value chains to try to exploit them. This opens an opportunity for Colombia to further promote its integration into the world global value chains and access new markets.

This paper explores the possibility of exporting teleworkable services from Colombia. The goal is to provide useful information to guide strategic interventions to speed-up the development of such service industries in Colombia.

We first introduce a definition of teleworkable jobs and describe its occupations and industries along different dimensions. We show that there are many teleworkable jobs in the US, representing a significant share of industry costs. Then, we show that many industries intensive in teleworkable jobs are currently traded across borders. To quantify Colombia’s advantage providing teleworkable services, we study the cost structure of industries and quantify the potential savings in overall costs if the tasks were performed by Colombians. Given Colombia’s current presence and the density around teleworkable industries we can calculate a proxy of the latent advantage in teleworkable services. We propose an index that summarize these dimensions and rank the potential gains from including telework from Colombia in an industry. We end with a set of policy recommendations to move this agenda forward.

Santos, M.A. & Hani, F., 2021. Diagnosing Human Capital as a Binding Constraint to Growth: Tests, Symptoms and Prescriptions. Cambridge University Press: Elements in the Economics of Emerging Markets. Publisher's VersionAbstract

The empirical literature on the contributions of human capital investments to economic growth shows mixed results. While evidence from OECD countries demonstrates that human capital accumulation is associated with growth accelerations, the substantial efforts of developing countries to improve access to and quality of education, as a means for skill accumulation, did not translate into higher income per capita. In this Element, we propose a framework, building on the principles of 'growth diagnostics', to enable practitioners to determine whether human capital investments are a priority for a country's growth strategy. We then discuss and exemplify different tests to diagnose human capital in a place, drawing on the Harvard Growth Lab's experience in different development context, and discuss various policy options to address skill shortages.

Lopesciolo, M., Muhaj, D. & Pan, C., 2021. The Quest for Increased Saudization: Labor Market Outcomes and the Shadow Price of Workforce Nationalization Policies.Abstract
Few countries have embraced active labor market policies to the same extent as Saudi Arabia. In the aftermath of the Arab Spring, the imperative of increasing Saudi employment became paramount. The country faced one of the highest youth unemployment rates in the world while over 80 percent of its private sector consisted of foreign labor. Since 2011, a wave of employment nationalization efforts has been mainly implemented through a comprehensive and strictly enforced industry and firm specific quota system known as Nitaqat. This paper assesses the employment gains as well as the costs and unintended consequences resulting from Nitaqat and related policies between 2011 and 2017. We find that while job nationalization policies generated significant initial gains in Saudi employment and labor force participation, the effects were heterogeneous across workers, firms and sectors. Moreover, our analysis suggests that the resulting unintended consequences far outweighed the benefits over time generating a less cost-effective and productivity inhibiting labor market composition.
 
Hani, F. & Lopesciolo, M., 2021. Understanding Saudi Private Sector Employment and Unemployment.Abstract

This paper analyzes the changes in Saudi employment and unemployment between 2009 and 2018 and argues that a supply-demand skill mismatch exacerbated by insufficient job creation, and prevalent Saudi preferences and beliefs about employment underpin the high unemployment problem that coexists with low Saudi employment in the private sector in the country.

Nano, E., Panizza, U. & Viarengo, M., 2021. A Generation of Italian Economists.Abstract

We examine the role of financial aid in shaping the formation of human capital in economics. Specifically, we study the impact of a large merit-based scholarship for graduate studies in affecting individuals’ occupational choices, career trajectories, and labor market outcomes of a generation of Italian economists with special focus on gender gaps and the role of social mobility. We construct a unique dataset that combines archival sources and includes microdata for the universe of applicants to the scholarship program and follow these individuals over their professional life. Our unique sample that focuses on the high end of the talent and ability distribution also allows us to analyze the characteristics of top graduates, a group which tends to be under-sampled in most surveys. We discuss five main results. First, women are less likely to be shortlisted for a scholarship as they tend to receive lower scores in the most subjective criteria used in the initial screening of candidates. Second, scholarship winners are much more likely to choose a research career and this effect is larger for women. Third, women who work in Italian universities tend to have less citations than men who work in Italy. However, the citation gender gap is smaller for candidates who received a scholarship. Fourth, women take longer to be promoted to the rank of full professor, even after controlling for academic productivity. Fifth, it is easier to become a high achiever for individuals from households with a lower socio-economic status if they reside in high social mobility provinces. However, high-achievers from lower socio-economic status households face an up-hill battle even in high social mobility provinces.

Ljubica Nedelkoska in HKS Magazine

THIS PAST YEAR HAS ILLUMINATED the fragility and failures of work in new ways. The coronavirus pandemic resulted in layoffs and furloughs for millions around the world. Some have lost their jobs in struggling or shifting industries and don’t have the skills to explore other fields. Many essential workers—from health aides to grocery clerks—have been forced to make grim trade-offs between personal health and financial security. Unpredictable and stressful schedules, discriminatory and unfair organizational practices and procedures,...

Schetter, U. & Tejada, O., 2020. On Globalization and the Concentration of Talent: A General Result on Superstar Effects and Matching.Abstract
We analyze how globalization affects the allocation of talent across competing teams in large matching markets. Focusing on amplified superstar effects, we show that a convex transformation of payoffs promotes positive assortative matching. This result holds under minimal assumptions on how skills translate into competition outcomes and how competition outcomes translate into payoffs. Our analysis covers many interesting special cases, including simple extensions of Rosen (1981) and Melitz (2003) with competing teams. It also provides new insights on the distributional consequences of globalization, and on the role of technological change, urban agglomeration, and taxation for the composition of teams.
