Empirical political economist studying governance and the political economy of development in Southeast Asia. I use natural experiments and large-scale field experiments with governments, multilateral institutions, and civil society to answer three questions: who stands for office (political selection), how they win office (accountability), and what they do once in office (governance).

With the advent of generative AI, and my view of how tremendously it will impact my home country, the Philippines, and the broader Southeast Asian region, I am pivoting my research to the political consequences of rapid and sweeping AI adoption. My current work uses the Anthropic Economic Index to trace the early labor-market effects of generative AI in the Global South, with evidence from Philippine business process outsourcing, one of AI's ground-zero casualties.

Generative AI and Labor Displacement in the Global South: Evidence from Philippine Business Process Outsourcing

Nico Ravanilla

Exported services have become for labor-abundant countries what manufacturing once was: a development path that absorbs large numbers of workers into internationally traded production. Generative AI performs many of the tasks these economies export, raising the possibility of labor displacement. I examine whether this displacement has begun in the Philippines, the economy most dependent on this path, by combining pre-ChatGPT occupational composition with occupation-level observed AI usage from the Anthropic Economic Index and tracing labor market outcomes as US client firms adopt AI. Employment growth slows in the most exposed provinces, industries, and municipalities, amounting to roughly a quarter million foregone jobs by mid-2025. The adjustment occurs through reduced hiring rather than layoffs: wages and hours do not change. The displaced enter unemployment, and first-time overseas departures fall rather than absorbing the workers the sector no longer hires.

Why leaders in weak countries posture with empty threats, and what it earns them.

PDF
Abstract

This study examines ‘theatrical’ foreign policy crises, an understudied part of international relations that is especially important among weaker nations. We argue that for less powerful countries often the symbolic statement or threat is the action itself, with parties to a conflict implicitly acknowledging that there is little real bargaining and no real shadow of war. Instead of the traditional audience cost, we hypothesize the opposite: a bump in political approval that accrues to leaders of weak nations when they make empty threats in crises of sovereignty, something we call a “posturing premium.” Examining the case of Southeast Asian nations abutting the South China Sea, we employ five survey experiments across four countries over the course of three original annual survey waves to test this proposition. We find that for foreign policy crises that are linked to sovereignty or national pride, leaders can generate a posturing premium by making threats that they later back down from, in contrast with existing empirical findings related to audience costs. This premium is significantly higher when empty threats are made against a strong adversary, rather than a weak one. However, when foreign policy crises are not plausibly related to sovereignty or territory, the usual audience costs dynamics return; this holds for both real and hypothetical crises. We validate the “weak country” scope condition by conducting an extension in a militarily stronger country, Japan, that does not find a posturing premium for comparable crises.

Local political outsiders, not entrenched incumbents, drove the deadliest phase of the drug war.

Abstract

Around the world, populists have won elections on the strength of crowd-pleasing, but norm-defying, policy proposals. Although effective at mobilizing support at election time, these policies are often difficult to implement in practice because populists lack allies throughout the political system. Examining President Rodrigo Duterte's brutal War on Drugs in the Philippines, we find that mayors excluded from existing establishment patronage networks filled this critical implementation gap. Employing regression discontinuity and difference-in-differences approaches, we demonstrate that outsider mayors received 40% lower public works appropriations and, in turn, executed Duterte's drug war much more aggressively. Outsider-led municipalities had 40% more antidrug incidents and 60% more extrajudicial killings by police. The results illustrate an important trade-off between patronage politics and corruption (politics as usual) and violent democratic backsliding.

How brokers use social networks and norms of reciprocity to mobilize voters in the Philippines.

LinkData
Abstract

Although canonical models of clientelism argue that brokers use dense social networks to monitor and enforce vote buying, recent evidence suggests that brokers can instead target intrinsically reciprocal voters and reduce the need for active monitoring and enforcement. Combining a trove of survey data on brokers and voters in the Philippines with an experiment-based measure of reciprocity, and relying on local naming conventions to build social networks, we demonstrate that brokers employ both strategies conditional on the underlying social network structure. We show that brokers are chosen for their central position in networks and are knowledgeable about voters, including their reciprocity levels. We then show that, where village social networks are dense, brokers prefer to target voters that have many ties in the network because their votes are easiest to monitor. Where networks are sparse, brokers target intrinsically reciprocal voters whose behavior they need not monitor.

Government outreach in conflict zones pays off later: villages engaged before Covid-19 reported risk more reliably during it.

LinkData
Abstract

Community information sharing is crucial to a government's ability to respond to a disaster or a health emergency, such as a pandemic. In conflict zones, however, citizens and local leaders often lack trust in state institutions and are unwilling to cooperate, risking costly delays and information gaps. We report results from a randomized experiment in the Philippines regarding government efforts to provide services and build trust with rural communities in a conflict-affected region. We find that the outreach program increased the probability that village leaders provide time-sensitive pandemic risk information critical to the regional Covid-19 Task Force by 20%. The effect is largest for leaders who, at baseline, were skeptical about government capacity and fairness and had neutral or positive attitudes towards rebels. A test of mechanisms suggests that treated leaders updated their beliefs about government competence and shows that neither security improvement nor project capture by the rebels are primary drivers. These findings highlight the important role that government efforts to build connections with conflict-affected communities can play in determining public health outcomes during times of national emergencies.

    The Philippines in 2025: Midterm Elections and the Reordering of Power, Policy, and Posture

    Nico Ravanilla · Asian Survey 66(2): 312-322

    Link
    Abstract

    This year-ender examines Philippine politics in 2025 through the lens of the May midterm elections and their effects on political, economic, and foreign policy incentives. As elections approached, institutional reform stalled and unresolved elite rivalries were reorganized into electoral competition, most visibly through impeachment efforts, alliance breakdowns, and Senate contests. Economic performance remained narrowly based, driven primarily by consumption amid weak investment, persistent planning constraints, and limited structural change, yet sufficiently stable to reduce pressure for difficult reforms. At the same time, corruption in infrastructure became unusually visible, exposing long-standing patterns of politically mediated contracting but without producing durable accountability. In foreign affairs, sustained pressure from China in the West Philippine Sea reinforced a familiar strategy centered on presence, legal framing, and alliance signaling rather than resolution. The result was continuity rather than transformation, as power, policy, and posture were reordered by electoral incentives rather than institutional change.

    How Street-Level Bureaucrats' Traits Affect Community Leaders' Assessments of the Government

    Nico Ravanilla, Dotan Haim, and Matthew Nanes · Journal of Politics 88(1)

    LinkData
    Abstract

    Research shows that bureaucrats' performance is shaped by their personal traits, such as public service motivation, cognitive ability, grit, and “big five” personality. What impact do these traits have on citizen assessments of service delivery and governance? To test this question, we randomly assigned police officers to villages during a community-oriented policing program in the Philippines. This program involved meetings between police officers and community leaders, citizens who serve as key conduits between the population and the state. We find that community leaders' assessments of individual officers were meaningfully affected by officers' personal traits, but those traits matter less for assessments of broader institutional efficacy. These findings suggest that bureaucrats' traits can improve public service provision by shaping how citizens approach encounters with specific government representatives. However, they place limits on the suggestion that exceptionally positive (or exceptionally negative) bureaucrats can shape attitudes towards state institutions more generally.

    How Does Community Policing Affect Police Attitudes? An Experimental Test and a Theory of Bureaucrat-Citizen Contact

    Winner, 2023 APSA Southeast Asian Politics Group Best Paper Award (Open Category)

    LinkData
    Abstract

    In contrast to the expansive work on how community policing affects citizens' attitudes toward police, existing research says little about how community policing affects officers' attitudes toward citizens. We examine officer-facing outcomes using an experiment in the Philippines, in which a random subset of a province's 705 officers were assigned to intensive community policing activities for seven months. Treatment officers saw improved understanding of citizen concerns, but did not develop greater empathy or trust toward civilians, nor an increased sense of accountability for citizen-facing misconduct. We build from the experiment to develop an inductive theory of bureaucrat-citizen contact, relying on qualitative observations and exploratory analyses of heterogeneous effects. We propose that contact with citizens is only likely to improve attitudes among frontline bureaucrats who are not ex-ante embedded in their communities. Moreover, contact may have negative effects when it reveals threats to bureaucrats' personal safety.

    The Extraordinary Effect of Religious Sect Endorsements on Vote Choice: Evidence from Iglesia ni Cristo's “Vote as One” Teaching

    Nico Ravanilla · Comparative Political Studies 58(13): 2755-2794

    LinkData
    Abstract

    Sects and strict denominations are growing more rapidly and retaining members better than mainstream religions. To what extent do they influence vote choice? I investigate whether the Iglesia ni Cristo (INC), a religious sect in the Philippines, can compel all members to “vote as one” and support a full ticket of endorsed candidates. Using a triple difference identification strategy, I show that the municipal-level vote-shares of INC-endorsed national candidates are unit elastic with respect to the share of INC voters across municipalities. Conventional low-information rationality models of voting cannot fully explain this. But augmented with social voting in which actions of other group members inform the objective function of voters, a voting model with religious sect endorsements can produce extremely large behavioral responses. These findings have implications on policy as well as on our understanding of strict religions' influence on politics.

    Poverty, Social Networks, and Clientelism

    LinkData
    Abstract

    Why are the poor susceptible to clientelism, and what factors shield them from the influence of vote buying? We explore the role of both formal and informal social networks in shaping the likelihood of being targeted with private inducements. We argue that when the poor lack access to formal social networks, they become increasingly reliant on vote buying channelled through informal networks. To test our theory, we build the informal, family-based network linkages between voters and local politicians spanning a city in the Philippines. We then collect survey data on formal network connections, electoral handouts, and voting behaviour of 900 voters randomly drawn from these family networks. We show first that campaigns disproportionately target poorer voters. We then show that familial ties further influence targeting among poor voters. Finally, we show that access to formal networks such as workers' associations mitigate voter fears of punishment for failing to reciprocate.

    Fire Alarms for Police Patrols: Experimental Evidence on Co-Production of Public Safety

    Matthew Nanes, Nico Ravanilla, and Dotan Haim · Journal of Politics 85(3): 1017-1032

    LinkData
    Abstract

    Effective public goods provision requires coproduction by both citizens and the government. Search costs that complicate citizens' ability to share information constitute a critical and understudied impediment to this coproduction. We experimentally evaluate search costs in a rural, conflict-affected province of the Philippines. We randomize the rollout of a police hotline that dramatically reduces the costs of reporting and compare it against both the status quo and an alternative intervention that builds trust but does not affect search costs. The hotline increased the likelihood of reporting crimes by 10-19 percentage points. The intervention reduced perceived insurgent activity but had no perceptible impact on ordinary crime. Our findings suggest that addressing search costs substantially improves service delivery, potentially explaining why policies imported from higher-capacity countries may fail to achieve results in developing contexts.

    When Legislators Don't Bring Home the Pork: The Case of Philippine Senators

    Nico Ravanilla and Allen Hicken · Political Science Research & Methods 11(4): 785-803

    LinkData
    Abstract

    Research in legislative politics suggests that the desire to get reelected encourages legislators to “bring home the pork” by delivering electorally rewarding, targeted spending. This is particularly true where the electoral system encourages incumbents to cultivate a personal vote. We analyze how Philippine Senators spend their Constituency Development Fund (CDF) and using the staggered elections to identify variation in reelection status, we show that senatorial reelectionists do not always bring home the pork. Because Philippine Senators are elected by plurality-at-large voting by the national electorate, they tend to spend their CDF allotments closer to elections but avoid allocating them disproportionately to their local strongholds. These findings illustrate how electoral rules can deter targeted spending but lead legislators to find alternative ways to build a personal vote.

    Voting in Clientelistic Social Networks: Evidence from the Philippines

    Nico Ravanilla, Michael Davidson, and Allen Hicken · Comparative Political Studies 55(10): 1663-1697

    LinkData
    Abstract

    In clientelistic environments, voters want to know which politicians are most likely to deliver on targeted benefits. We argue that in these contexts, voters use their social proximity with candidates as heuristics to inform vote choice. To test our theory, we rely on local naming conventions to reconstruct family networks spanning one whole city in the Philippines and assess blood and marriage links between voters and local candidates. We then collect survey data on pre-election candidate leanings and actual voting behavior of 894 randomly drawn voters. We show that the degrees of separation between voters and candidates explain not only aggregate electoral outcomes, as previous studies have found, but also individual vote choice, controlling for pre-election leanings. We demonstrate that this is because private inducements are channeled through family networks. These findings highlight the electoral importance of social proximity with politicians as an information shortcut when voters are choosing whom to support at the polls.

    Community Policing Does Not Build Citizen Trust in Police or Reduce Crime in the Global South

    LinkData
    Abstract

    Is it possible to reduce crime without exacerbating adversarial relationships between police and citizens? Community policing is a celebrated reform with that aim, which is now adopted on six continents. However, the evidence base is limited, studying reform components in isolation in a limited set of countries, and remaining largely silent on citizen-police trust. We designed six field experiments with Global South police agencies to study locally designed models of community policing using coordinated measures of crime and the attitudes and behaviors of citizens and police. In a preregistered meta-analysis, we found that these interventions led to mixed implementation, largely failed to improve citizen-police relations, and did not reduce crime. Societies may need to implement structural changes first for incremental police reforms such as community policing to succeed.

    Temptation in Vote Selling: Evidence from a Field Experiment in the Philippines

    Allen Hicken, Stephen Leider, Nico Ravanilla, and Dean Yang · Journal of Development Economics 131: 1-14

    LinkData
    Abstract

    We test the predictions of a behavioral model of transactional electoral politics in the context of a randomized anti-vote-selling intervention in the Philippines. We model selling one's vote as a temptation good: it creates positive utility for the future self at the moment of voting, but not for past selves who anticipate the vote-sale. We also allow keeping or breaking promises regarding vote-selling to affect utility. Voters who are at least partially sophisticated about their vote-selling temptation can thus use promises not to vote-sell as a commitment device. An invitation to promise not to vote-sell is taken up by a majority of respondents, reduces vote-selling, and has a larger effect in electoral races with smaller vote-buying payments. The more effective promise treatment reduces vote-selling in the smallest-stakes election by 10.9 percentage points. Inviting voters to make another type of promise, to accept vote-buying payments but to nonetheless “vote your conscience,” is significantly less effective. The results are consistent with voters being partially (but not fully) sophisticated about their vote-selling temptation.

    Abstract

    Using data from an anti-vote-buying field experiment we conducted in the Philippines, we report and validate a proxy measure for vote-selling. We demonstrate that our proxy measure, vote-switching, changes as expected with voter preferences and monetary offers from candidates. Voters are less likely to vote for someone different than their initial preference the larger the favorability rating difference between the preferred and alternative candidates. Similarly, vote-switching increases the more money the alternative candidate offers compared to the preferred candidates. We also describe the effects of the promise-based interventions on vote-switching, reported in full in a companion paper.

  • Not All Political Dynasties Are Equal: Organizational Configurations and Electoral Entrenchment

    Nico Ravanilla · Working paper · Prepared for EuroSEAS 2026

    PDF
    Abstract

    Political dynasties can shape economic institutions, public policy, and the distribution of resources in ways that reinforce their political dominance. Yet although dynasties are, by definition, organizations spanning multiple elected offices, existing research has largely treated them as organizationally homogeneous. Using the universe of Philippine local elections from 1992 to 2025, I exploit close elections in regression discontinuity designs to estimate the causal electoral advantage of alternative dynastic configurations. Most configurations confer little or no electoral advantage. One transforms incumbency: families spanning both the mayoralty and the district's House seat retain power substantially more often and win subsequent elections by much larger margins. Dynastic entrenchment depends less on family lineage than on the organizational configurations through which political families span different levels of government.

  • The Positional Value and Redistributive Consequences of the Ballot Grid: Evidence from the Philippine Party-List Switch from an Alphabetical to a Randomized Ballot Grid

    Nico Ravanilla and Lucas Zeng · Working paper · July 2026 draft

    PDF
    Abstract

    The crowded ballots of modern democracies are grids, not lists. Where a candidate sits in the grid decides whether voters ever reach them, with real consequences for representation. We exploit the Philippine party-list election, whose four-column grid of up to 187 organizations was ordered alphabetically in 2010 and randomized in five elections since. The raffles identify the causal effect of grid position on vote share: moving from the tenth slot to the hundredth costs an organization 30 percent of its votes. Because positions vary by row and column, the grid reveals which scanning behavior produces the losses, something the single-column ballots of prior research cannot. Under the alphabet, the weakest organizations captured the best positions through strategic renaming; the raffle ended the capture and prevented its entrenchment. However, it still reallocated four to five seats every cycle to lucky drawers, suggesting a need to address ballot randomization's redistributive effects.

  • Patrons, Bosses, and Brokers: A Theory of Local Development in the Philippines' Patronage Democracy

    Nico Ravanilla · Working paper · June 2026 draft

    PDF
    Abstract

    Entrenched political elites dominate Philippine local politics, yet localities governed by observationally similar elites trace out strikingly different development trajectories. I develop a principal-agent model of the fiscal relationship between constituents and local politicians in which, following Fabella [2005], contract design is embedded in a weak governance environment, so that rents and clientelist transfers emerge endogenously. The familiar figures of Philippine local politics (patrons, bosses, and brokers) arise as regions of a single parameter space, interacting with the constituents' participative capacity. With participative constituents, the optimal fiscal constitution is insulated from the politician's type; with minimally participative constituents, brokers improve while bosses degrade contract efficiency; and with passive constituents facing bossist politicians, no incentive-compatible constitution exists, generating a low-provision, low-growth trap. Twelve well-documented provincial dynasties and 25 years of provincial fiscal records illustrate each configuration of the typology. The model rationalizes stylized contrasts across Philippine provinces and implies that performance-based intergovernmental transfers can substitute for the fiscal contract that weak communities cannot write for themselves.

  • Which Principals Matter? Accountability When Local Officials Answer to Both Bureaucrats and Politicians

    Matthew Nanes, Nico Ravanilla, and Dotan Haim · Working paper · July 2026 draft

    PDF
    Abstract

    Government service provision often relies on local officials who implement policy while answering to overlapping administrative and political authorities. Yet we know little about which principals induce responsiveness in such settings. We study this question using a randomized evaluation of a local security reform in the Philippines. Village officials received an identical accountability letter that varied only in the identity of the principal issuing it: a national agency with formal administrative authority or the municipal mayor whose influence rests on informal patronage. Officials increased participation only in response to the national agency's letter. Citizens in villages where officials received the agency letter also reported higher perceptions of government fairness and effectiveness. These findings provide evidence on accountability among local implementers with one foot in politics and the other in bureaucracy, and motivate a discussion of when similar officials in other settings respond to accountability from one principal rather than another.

  • The Effects of a Politician-Targeted Social Accountability Initiative on Public Works Provision: Evidence from a Large-Scale Experiment in the Philippines

    Nico Ravanilla, Eitan Paul, Allen Hicken, and Ronald Mendoza · Working paper

    Abstract

    Politicians often use public works procurement to further their own interests. We test whether a social accountability initiative targeted at politicians can alter such behavior in a weak-oversight setting. We randomly assigned half of the legislative offices in the Philippines to receive advocacy from a civil society organization encouraging more transparent and efficient public works provision, half of which were also told their performance would be reported to media outlets. On average, the advocacy prompted legislators to prioritize less corruption-prone projects, but it had no effect on transparency or geographic allocation. Moreover, it decreased the competitiveness and quality of construction contracting. Politicians from dynasties, insecure seats, or seeking re-election were least responsive to the advocacy. The threat of media coverage offset these adverse effects. Overall, our findings suggest that bottom-up information campaigns can influence elite behavior even in settings with weak governmental oversight, though effects are modest and context-dependent.
