Human Capital, Mobility, and Adaptation to Climate Change

Can those in poverty adapt to climate change in time? To explore this question, I examine the role of human capital in generating mobility across sectors or locations, a key mechanism for the poor to adapt to climate change. Using a historical schooling expansion in India, I provide reduced-form evidence on the role of human capital in facilitating adaptation to climate change in the long term. Those with greater human capital leave agriculture in response to a worsening climate. To understand the role of human capital in supporting adaptation in general equilibrium, I then develop a spatial structural change model with climate change, occupational choice, and pre-period investments into mobile human capital. Lower labour market access and non-homothetic preferences drag down relative investments into human capital in rural areas. The slower accumulation of human capital leaves the rural poor less able to compete in markets for human capital, harming their prospects for adaptation. Finally, I estimate the model to study how optimal human capital subsidies mitigate the overall welfare costs of climate change by speeding up adaptation.

The Economic Costs of Distorted Power Tariffs: Evidence from Power Purchase Agreements in Pakistan

We document the extent of generosity in existing power purchase agreements in Pakistan by assembling a database on all contracts and revisions to date. A simple model of procurement under asymmetric information and regulatory capture is developed to frame why the cost of power is so high in Pakistan. Using the model, we measure the size of the distortion caused by these market failures and estimate the static economic costs of these distortions on firms. Lastly, we consider the dynamic costs and inefficiencies resulting from this long-run agreements.

Enhancing Enforcement through Religious Institutions: Experimental Evidence from Pakistan’s Power Sector

(with Robin Burgess, Michael Greenstone, Faraz Hayat & Usman Naeem)

The ability of governments to expand energy access runs aground when state capacity is limited. Weak enforcement creates a leaky bucket as electricity theft and unpaid bills go unchecked. As a result, energy access gets curtailed, especially for the poor. Together with the government of Pakistan, we are evaluating a novel intervention that seeks to shift social norms on the payment of electricity in areas beyond the reach of the state. Influential agents, notably local religious institutions (mosques), will deliver messages against electricity theft in treatment communities. A separate treatment arm provides financial incentives to pay for electricity. We use our experimental estimates to derive demand curves for electricity and theft using a simple theoretical model to quantify the fiscal value of the enforcement intervention. Our study takes place in Khyber Pakhtunkhwa, a rural, poor, and highly religious area of Pakistan where theft is widespread, making it an ideal setting to test if this is a cost-effective solution. Our proposal builds on a long-term engagement with the highest levels of the federal government in Pakistan.

Deciphering the Miracle on the Han:
How South Korea Escaped Poverty and Transformed its Economy

(with Ignacio Banares Sanchez, Oriana Bandiera, Robin Burgess, Jay Euijung Lee, Jeongkyun Won & Hyunjoo Yang)

Britain’s industrial revolution in the late 18th century turned a page in the story of civilisation. Just like Britain, South Korea rose from poverty to become a leading industrialised economy today. Yet the ‘miracle on the Han River’, as South Korea’s growth experience is famously called, is not merely about how one country escaped poverty. The miracle is how it did so in such a dramatic, condensed timeline. This is the miracle that we wish to decipher. Are these changes a result of fate (fortunate fundamentals) or foresight (direct results of policies and other interventions)? We are creating an unprecedented historical database tracking all facets of South Korea’s structural transformation from the mid- to late-20th century. Utilising newly digitised historical micro data on output, firms, employment, migration, urbanisation, and infrastructure, we study the policies and channels through which the country achieved its remarkable transformation.

The Heterogeneous Impacts of Market Integration:
Evidence from Pakistan's Motorways

(with Faraz Hayat & Usman Naeem)

Across the world cranes and excavators are abuzz building out and upgrading transportation infrastructure.  As markets within and across countries become more integrated, the ability for firms to trade flourishes. Such integration, however, creates winners and losers, with some firms reaping the rewards while others perish. This project studies the heterogeneous impacts of expanding transportation infrastructure and how these effects translate to changes in the spatial distribution of economic activity. Drawing on a vast administrative dataset of all formal firms in Pakistan, we examine the rollout of several large-scale motorways that were designed to connect the north and south of the country. Using quasi-exogenous variation in motorway access we examine the firm-level responses to the arrival of motorways (such as how networks, products offered, and prices shift).

The General Equilibrium Effects of Electricity Access:
Evidence from Myanmar

(with Robin Burgess, Michael Greenstone, Niclas Moneke & Nicholas Ryan)
[Permanently on hold following military coup in February 2021]

There is a conviction that energy is transformative for economic growth. Yet, we have little evidence for how this transformation happens. We will evaluate a massive electrification drive in Myanmar which aims to bring access to 100%, up from 42% today, by 2030.  Our focus is on both the aggregate and the micro levels, consisting of a nationwide evaluation that monitors economic outcomes as infrastructure expands across the country and an embedded experiment that varies electrification access by subsidising connections. This will allow us to analyse the aggregate, microeconomic, and spillover effects from a large-scale infrastructure intervention. We draw on an unprecedented geospatial administrative dataset covering every single pole, line, and transformer in the country and exploit a distance-based threshold that determines village eligibility for electrification in a given phase to arrive at estimates on the effect of expanding electricity access.
