Abstract: This paper measures the impacts of the world’s largest modern agricultural export expansion—that of Indonesian palm oil since 2000—on regional poverty and consumption. Identification exploits geographic differences in suitability for cultivation and rapid growth in global demand. The median expansion led to 2.7 percentage points faster poverty reduction and 4 percent faster consumption growth. Results can be explained by rising returns to labor and land, and indirect effects through investment, fiscal linkages, and public goods. Each percentage point of palm-driven poverty reduction corresponds to a 1.5–3 percentage point loss of forest area.

WORKING PAPERS

“Spillovers from agricultural processing” [presentation] [paper] First draft: August 2018. New draft coming soon.

Abstract: Can growth in export agriculture ease the transition out of agriculture? This paper uses the proliferation of palm oil factories across Indonesia's outer islands to study industrial onset and estimate spillovers from agricultural processing. Using two identification strategies—comparing villages near factories to those farther away, and combining cultivation suitability and export port proximity into an instrument for factory exposure—I find that villages near factories have more people, firms, and other economic and social organizations. Processing also increases incomes and non-agricultural employment. Employment effects are similar for migrants and locals. These patterns can be at least partially explained by growth in linked industries, infrastructure, and local market integration.

“Causes of Indonesia’s forest fires”, with Wally Falcon, Matt Higgins, and Roz Naylor (Stanford). First draft: April 2016 (available on request).

FiresbyVillKal2015.jpg

Abstract: The economic costs of Indonesia’s 2015 forest fires are estimated to exceed US $16 billion, with more than 100,000 premature deaths. On several days the fires emitted more carbon dioxide than the entire United States economy. Here, we combine detailed geospatial data on fire and local climatic conditions with longitudinal administrative data to assess the underlying anthropogenic causes of Indonesia's forest fires. Political decentralization increased fire and exacerbated the fire impacts of El Nino. Local economic growth, particularly rural manufacturing, has also gone hand-in-hand the use of fire in rural districts. We proceed with a 30,000-village case study of the catastrophic 2015 fire season on Sumatra and Kalimantan. Villages more likely to burn tend to be less developed, more remote, exposed to palm oil supply chains, and have a history of burning for agriculture.

“Local impacts of resource booms”, with Paul Burke (ANU). First Draft: June 2016 (available on request).

Abstract: We study the local impacts of three types of natural resource sector booms in Indonesia, one of the world's largest resource exporters. Applying the synthetic control method to district-level data over the 2000s, we examine palm oil in Sumatra, coal mining in Kalimantan, and natural gas extraction in West Papua. Findings are consistent with an inverse relationship between concentration of natural resource rents and benefit diffusion, including spillovers to other sectors of the local economy. All three resource booms boosted total economic output in per capita terms. Oil palm expansion raised agricultural, industrial, and services output, while coal mining reduced agriculture and services output. Oil palm and coal mining booms both appear to have delivered strong local poverty reduction. The natural gas project in West Papua delivered a massive increase in industrial and aggregate output, but appears to have had insignificant impacts on household welfare or poverty. Similar patterns are observed in additional cases and when using all cases in a panel setup.

Project summary: Payments for ecosystems services (PES) and conditional cash transfers (CCTs) are popular and often effective policy approaches to spur behavior change: paying people to undertake behaviors they otherwise would not. Usually, the behavior being “incentivized” benefits society, for example reducing deforestation with PES and vaccination and school attendance in CCTs. However, there remains limited evidence on the effectiveness of PES-type interventions, particularly in weak institutional settings, and no studies have focused on fire, the main way to clear land in the developing tropics. Our study is based in West Kalimantan, a province where Indonesia’s catastrophic 2015—16 fires were concentrated. We estimate the effects of conditional cash transfers to reduce fire—offered as PES contracts to village governments—by randomly assigning 75 villages to the program and 200 to a comparison group. Villages must not set any fire and promptly extinguish any natural fires to receive their ex-post payment. Hence, payment is conditional on performance, which we monitor using satellite data and field verification. Our intention is to scale up with additional treatment arms—different payment levels and information-only treatments—if the initial results in January 2019 are promising.
