"Global progress and backsliding on gasoline taxes and subsidies."
Nature Energy. vol. 2, no. 16201 (January 2017). Co-authored with Michael Ross and Chad Hazlett.

To reduce greenhouse gas emissions in the coming decades, many governments will have to reform their energy policies. These policies are difficult to measure with any precision. As a result, it is unclear whether progress has been made toward important energy policy reforms, such as reducing fossil fuel subsidies. We use new data to measure net taxes and subsidies for gasoline in almost all countries at the monthly level and find evidence of both progress and backsliding. From 2003 to 2015 gasoline taxes rose in 83 states but fell in 46 states. During the same period, the global mean gasoline tax fell by 13.3 percent due to faster consumption growth in countries with lower taxes. Our results suggest that global progress toward fossil fuel price reform has been mixed, and that many governments are failing to exploit one of the most cost-effective policy tools for limiting greenhouse gas emissions.

"Explaining the Oil Advantage: Effects of Natural Resource Wealth on Incumbent Reelection in Iran."
World Politics. vol. 67, no. 2 (April 2015), pp. 226-267.

[Replication Materials] • [Supplementary Appendix]

Why does natural resource wealth prolong incumbency? Using evidence from parliamentary elections in the Islamic Republic of Iran, I show that natural resource revenues boost incumbent reelection rates because this revenue is used to provide public or private goods to constituents, incentivizing voters to reelect incumbents over challengers. To test this hypothesis, I employ originally assembled data on five parliamentary elections in Iran (1992-2008) in longitudinal hierarchical regression analysis at the district and province level. By leveraging Iran's mixed-member electoral system, I am able to show that the resource-incumbency mechanism works primarily in single-member districts with little evidence of an incumbency advantage for politicians in resource-rich multi-member districts. Building on the rentier theory of natural resource wealth, my results suggest that voting for the incumbent is attributable to patronage and public goods distribution. My findings offer new insights into the understudied context of Iranian legislative elections, illustrate the mechanisms driving the relationship between resource wealth and incumbency advantage at the sub-national level in a non-democratic setting, and highlight the mediating effects of electoral institutions on the resource-incumbency relationship.

"Why Do Leaders Nationalize the Oil Industry? The Politics of Resource Expropriation."
Energy Policy. vol. 75, no. C (December 2014), pp. 228-243.

[Replication Materials] • [Supplementary Bibliography]

Why do leaders nationalize the oil industry? In line with a general utility-maximizing theory, I argue that leaders nationalize to maximize state revenues while minimizing costs. The latter includes international retaliation and domestic political constraints. Using a novel longitudinal dataset on the establishment of national oil companies (NOCs), the empirical evidence presented in this paper lends support to four primary findings. States are most likely to establish NOCs (1) in periods of high oil prices, when the risks of expropriation are outweighed by the financial benefits; (2) in non-democratic systems, where executive constraints are limited; (3) in `waves', that is, after other countries have nationalized, reflecting reduced likelihood of international retaliation; and, though with weaker empirical support, (4) in political settings marked by resource nationalism. This last factor is proxied by OPEC membership in large-N analysis and, in a two-case comparison, by the difference in retained profits between the host and foreign governments. The theory and empirics presented here offer some clues for policy makers and multinational companies alike as to when to expect leaders to opt for nationalization.

"The Institutional Components of Political Corruption." 2015. In Ruben Ruiz Rufinio and Jennifer Gandhi (eds.), Handbook of Comparative Political Institutions (New York: Routledge Press). Co-authored with Miriam Golden.

This chapter reviews what we have learned in the last twenty-five years about how formal political institutions affect political corruption, understood as the misuse of public office for private or partisan gain. We discuss the impact of basic political institutions in established democratic polities on corruption: executive institutions; electoral institutions; federalism; and, finally, judicial institutions. A second section considers how whether and when voters punish corrupt politicians and how political corruption affects the performance of government bureaucracy, especially as regards service delivery. Finally, we discuss possible explanations for why the establishment of democratic political institutions appears to exert so little influence on the degree of political corruption. Our analysis of existing literature attends to problems of casual inference. Looking ahead to future studies, we suggest that the most fruitful research in the next decade will be subnational, experimental or quasi-experimental, and non-institutional.

"Oil, monarchy, revolution, and theocracy: a study on the National Iranian Oil Company (NIOC)." 2012. In David Victor, David Hults and Mark Thurber (eds.), Oil and Governance (Cambridge, UK: Cambridge University Press).

This chapter looks at the history of the National Iranian Oil Company (NIOC) and how its structure and operations are integrated with the Iranian state and the company's political masters. Using evidence from the Central Bank of Iran, the Ministry of Petroleum, and field interviews with former NIOC officials, I argue that NIOC's relationship with the state has shifted from a strategy of compliance under the Shah (1954-1979), to autonomy after the revolution (1979-2004) and back again to strict compliance in the Ahmadinejad era (2005-2012). This dynamic strategy corresponds with NIOC's performance: strong before the revolution, weak during the early period of the Islamic Republic, moderately successful in the 1990s, and inefficient during the Ahmadinejad period. Ultimately, my findings suggest that the root cause of NIOC's production woes is the company's lack of autonomy from the government.

"Scraping public co-occurrences for statistical network analysis of political elites."
Conditionally accepted at Political Science Research & Methods.

[Replication Materials] • [Supplementary Appendix]

Collecting network information on political elites using conventional methods such as surveys and text records is challenging in authoritarian and/or conflict-ridden states. I introduce a data collection method for elite networks using scraping algorithms to capture public co-appearances of individuals at political and social events. After validating the method with existing elite network data in the US, Mexico, and North Korea, I apply the technique to Nigeria to show that, in contrast to existing work, patronage does not drive presidential appointments to the state-owned oil company. Given that theories on elite behavior aim to understand individual-level interactions, the applicability of data using the proposed technique is large, especially in situations where intrusive data collection is costly or prohibitive.

"Oil, corruption, and the institutions that foster transnational bribery." (under review)


While some oil-rich countries are highly corrupt, others have transparent and well- functioning governments. What explains this wide variation in so-called 'resource-cursed' states? I show that these differences result from institutional choices over how oil extraction is governed. Some governments grant contract-awarding authority to national oil companies (NOCs), while others place this authority in ministries. I argue that this choice matters: because of their fiscal opacity and lack of oversight, NOCs foster bribery in the procurement process whereas ministries disincentivize such corrupt behavior. Using new data on transnational bribes involving high-level government officials in 59 oil-producing countries, I show evidence for a robust link between oil-related institutions and grand corruption, even after addressing the endogeneity of institutional choice via instrumental variables analysis. This research has implications not only for the political economy of the resource curse hypothesis, but also for existing theories on the micro-foundations of international corruption.

"How Taking from Foreigners Affects Domestic Human Rights." Oxford University Blavatnik School of Government Working Paper Series, BSG-WP-2015/004. (with Noel Johnston and Nicole Janz)

David Hume and the founders of the market economy argued that it is critical for a government to protect the property rights of its citizens. It is unclear, however, if this applies to foreign-owned property as well. By international law, an expropriation (i.e. involuntary seizure of foreign-owned assets) is only legal if undergone for a public purpose. Government leaders often attest this is the case. But in reality, does seizing assets of foreigners typically benefit the public? We argue that it does not. This project brings together two literatures in political science, and is the first to rigorously analyze the consequences of international expropriations for domestic political, economic and labor rights. Using case studies and a variety of statistical tests, we argue that, while expropriations create short-term windfall profits for a government, they may do overall damage to the public good by chasing away welfare-enhancing investors and creating revenue for government repression. This article is an appeal to those who take for granted the welfare implications of international investment policies. It suggests that any major reconsideration of the investment regime must also consider how it affects people on the ground. Without scholars and policymakers asking these questions, it will be difficult to fully address the bigger question of the optimal design of an international investment regime.

"No taxation, no representation? Oil-to-cash transfers and the dynamics of government responsiveness."

Does the absence of taxation lead to a lack of representation? The answer to this question is at the heart of decades of scholarly work on natural resource politics---notably the purported causal mechanism that links resource rents to the resilience of anti-democratic institutions. One microfoundation underpinning this mechanism is that taxes strengthen citizen demands for government accountability, whereas resource rents weaken such demands through the distribution of state-provided goods and hand-outs. I look to the next sequential step in this mechanism by shifting the focus from citizens to how leaders behave differently when taxes are replaced with resource wealth. In the context of Alaskan state politics, I show that the decision to repeal state taxes in 1980 and to distribute unconditional oil-to-cash transfers starting in 1982 prompted a decline in government responsiveness. To test whether citizen acquiescence drives this effect, I examine a natural experiment in the context of voting in the 1976 general election by recipients of the Longevity Bonus, a now-defunct conditional oil-to-cash transfer program that preceded the current Permanent Fund Dividend. These findings bear theoretical implications not only for the study of natural resource politics but also the broader study of the determinants of representative government.

"Share the Wealth? How Leaders Distribute Natural Gas Revenues in Peru." (with Felipe Nunes)

How do political leaders distribute discretionary revenue? In this paper we use evidence from Peru to show that President Alan Garcia opportunistically distributed natural gas revenues to improve his political legacy among Peruvian voters. Our findings support the claim that Garcia had lasting office-seeking, as opposed to policy-seeking, motivations for resource allocation. Our findings have substantive implications for leaders in resource-rich states contemplating the decentralization and subnational distribution of natural resource revenues.
