The Us-China Trade War And Global Reallocations, Pablo Fajgelbaum, Pinelopi Goldberg, Patrick Kennedy, Amit Khandelwal, Daria Taglioni

Discussion Papers

We study global trade responses to the US-China trade war. We estimate the tariff impacts on product-level exports to the US, China, and rest of world. On average, countries decreased exports to China and increased exports to the US and rest of world. Most countries export products that complement the US and substitute China, and a subset operate along downward-sloping supplies. Heterogeneity in responses, rather than specialization, drives export variation across countries. Surprisingly, global trade increased in the products targeted by tariffs. Thus, despite ending the trend towards tariff reductions, the trade war did not halt global trade growth.

Aggregate Implications Of Barriers To Female Entrepreneurship, Gaurav Chiplunkar, Pinelopi K. Goldberg

Discussion Papers

We develop a framework for quantifying barriers to labor force participation (LFP) and entrepreneurship faced by women in developing countries, and apply it to the Indian economy. We find that women face substantial barriers to LFP. The costs for expanding businesses through the hiring of workers are also substantially higher for women entrepreneurs. However, there is one area in which female entrepreneurs have an advantage: the hiring of female workers. We show that this is not driven by the sectoral composition of female employment. Consistent with this pattern, we find even without promoting female LFP, policies that boost female entrepreneurship …

The Economics Of The Covid-19 Pandemic In Poor Countries, Edward Miguel, Ahmed Mushfiq Mobarak

Discussion Papers

The COVID-19 pandemic has upended health and living standards around the world. This article provides an interim overview of these effects, with a particular focus on low- and middle-income countries (LMICs). Economists have explained how the pandemic is likely to have differential consequences for LMICs, and demand distinct policy responses, compared to rich countries. We survey the rapidly expanding body of empirical research that documents its many adverse economic and non-economic effects in terms of living standards, education, health, and gender equality, which appear to be unprecedented in depth and scale. We also review research on successful and failed policy …

The Impact Of Community Masking On Covid-19: A Cluster-Randomized Trial In Bangladesh, Jason Abaluck, Laura H. Kwong, Ashley Styczynski, Ashraful Haque, Md. Alamgir Kabir, Ellen Bates-Jeffries, Emily Crawford, Jade Benjamin-Chung, Salim Benhachmi, Shabib Raihan, Shadman Rahman, Neeti Zaman, Peter J. Winch, Md. Maqsud Hossain, Hasan Mahmud Reza, Stephen P. Luby, Ahmed Mushfiq Mobarak, Abdulla All Jaber, Shawkee Gulshan Momen, Faika Laz Bani, Aura Rahman, Tahrima Saiha Huq

Discussion Papers

Background: Mask usage remains low across many parts of the world during the COVID- 19 pandemic, and strategies to increase mask-wearing remain untested. Our objectives were to identify strategies that can persistently increase mask-wearing and assess the impact of increasing mask-wearing on symptomatic SARS-CoV-2 infections.

Methods: We conducted a cluster-randomized trial of community-level mask promotion in rural Bangladesh from November 2020 to April 2021 (N=600 villages, N=342,126 adults). We cross-randomized mask promotion strategies at the village and household level, including cloth vs. surgical masks. All intervention arms received free masks, information on the importance of masking, role modeling by community …

Economic Development, The Nutrition Trap And Metabolic Disease, Nancy Luke, Kaivan Munshi, Anu Mary Oommen, Swapnil Singh

Discussion Papers

This research provides a single explanation for: (i) the persistence of malnutrition and (ii) the increased prevalence of metabolic disease (diabetes, hypertension, cardiovascular disease) among normal weight individuals with economic development. Our model is based on a set point for BMI or bodyweight that is adapted to conditions of scarcity in the pre-modern economy, but which subsequently fails to adjust to rapid economic change. During the process of development, some individuals thus remain at their low-BMI set point, despite the increase in their consumption, while others who have escaped the nutrition trap (but are not necessarily overweight) are at increased …

Returns To International Migration: Evidence From A Bangladesh-Malaysia Visa Lottery, Ahmed Mushfiq Mobarak, Iffath A. Sharif, Maheshwor Shrestha

Discussion Papers

We follow 3,512 (of 1.4 million) applicants to a government lottery that randomly allocated visas to Bangladeshis for low-skilled, temporary labor contracts in Malaysia. Most lottery winners migrate, and their remittance substantially raises their family’s standard of living in Bangladesh. The migrant’s absence pauses demographic changes (marriage, childbirth, household formation), and shifts decision-making power towards females. Migration removes enterprising individuals, lowering household entrepreneurship, but does not crowd out other family members’ labor supply. One group of applicants were offered deferred migration that never materialized. Improved migration prospects induce pre-migration investments in skills that generate no returns in the domestic market.

Slippery Fish: Enforcing Regulation When Agents Learn And Adapt, Andres Gonzalez Lira, Ahmed Mushfiq Mobarak

Discussion Papers

Attempts to curb undesired behavior through regulation gets complicated when agents can adapt to circumvent enforcement. We test a model of enforcement with learning and adaptation, by auditing vendors selling illegal fish in Chile in a randomized controlled trial, and tracking them daily using mystery shoppers. Conducting audits on a predictable schedule and (counter-intuitively) at high frequency is less effective, as agents learn to take advantage of loopholes. A consumer information campaign proves to be almost as cost-effective and curbing illegal sales, and obviates the need for complex monitoring and policing. The Chilean government subsequently chooses to scale up this …

The Productivity Consequences Of Pollution-Induced Migration In China, Gaurav Khanna, Wenquan Liang, A. Mushfiq Mobarak, Ran Song

Discussion Papers

Migration and pollution are two defining features of China's impressive growth performance over the last 30 years. In this paper we study the migration response to pollution in Chinese cities, and its consequences for productivity and welfare. We document a robust pattern in which skilled workers emigrate more in response to pollution than the unskilled. Their greater sensitivity to air quality holds up in cross-sectional variation across cities, panel variation with individual fixed-effects, and when instrumenting for pollution using distant power-plants upwind of cities, or thermal inversions that trap pollution. Pollution therefore changes the spatial distribution of skilled and unskilled …
