I am an applied microeconomist, who works on issues related to Environmental Economics and Development Economics. Most of my work uses theoretical and econometric models to examine the impact of institutional changes on socioeconomic outcomes, such as firm productivity and legal disputes, in China and Sub-Saharan Africa. However, I am also interested in macroeconomic questions related to the use and management of natural resources.

Working Papers:

Delegation of Regulation and Perceived Corruption in South Africa (pdf)

In this paper, I study the economic motivations behind a reduction in the discretionary power of environmental inspectors, and show the impact that such reduction has on perceived corruption in South Africa. I examine the transition from the Air Pollution Protection Act of 1965 to the Air Quality Act of 2005, a change from full to partial delegation of regulation. By constructing a principal-agent model, I argue that this transition might have occurred because of an increase in inspectors’ rent-seeking motivation and capacity of appropriating rents. I then employ diff-in-diffs models for a two-period panel with 191 South African firms to show that the regulatory change decreased treated firms’ perceived corruption, but did not improve other institutional quality measures.

Food Security and Global Public Good Provision – A Macroeconomic Approach to Land Use Policy, with Ozgun Haznedar, Bruno Lanz and Tim Swanson (pdf)

It may be important to dedicate substantial parts of the global land supply to public good uses in the 21st century, for purposes of climate change management and biodiversity provision. But will it also be possible to meet the food requirements of 12 billion people while doing so? Using a macroeconomic model, we demonstrate that it may be possible to provide both for food security and environmental services in the long run. We first show that it may be possible to provide for food security with very substantial constraints on the amount of land used in agriculture with relatively minor welfare losses. We then show that global policies that re-allocate labour across sectors of the economy may have the capacity for directing the economy toward reduced reliance on land in agriculture. Focusing on education, research and development, and fertility costs may be the best way to meet these combined goals.

Heterogeneous Impacts of School Fee Elimination in Tanzania: Gender and Colonial Infrastructure, with Roxana Manea

In this study, we investigate the impacts of the 2002 elimination of primary school fees in Mainland Tanzania. We explore how the magnitude of these effects depends on gender and the size of early investments in the educational infrastructure of Tanganyika. We use the 2002 and 2012 census waves as well as historical information on the location of schools in the late 1940s, and conduct a difference-in-differences analysis. We find that exposure to an average of 1.7 years of free primary education has reduced the proportion of people who have never attended primary education by 6.8 percentage points. The benefits of fee removal have been significantly larger for females compared to males, and females from districts where the size of investments in education was relatively larger during colonial rule have been the greatest beneficiaries.
