I study the effects of traditional chiefs – a common type of broker – on voters’ ability to extract state resources from politicians. Using original data from Northern Ghana, I show that chieftaincy positions invented by colonial authorities are especially prone to capture, leaving voters worse off compared both to more accountable chiefs whose authority dates to the pre-colonial period and to voters who lack formal chiefs who can serve as brokers. The latter comparison exploits exogenous assignment of ethnic groups to the colonial invention of chieftaincy in the late-19th century. The findings suggest that whether voters benefit from brokers amidst clientelistic electoral competition depends on the accountability relationship between brokers and their clients.

Political competition is expected to become less particularistic as prosperity rises and a middle class emerges. But particularistic linkages persist despite rising wealth in urban Ghana.  Politicians are unable to  commit to campaign promises with voters who want large-scale public policies, many of whom are in the middle class. This creates incentives to avoid mobilizing many of these voters and to ignore their preferences. As a result, voters who want major public policies rather than patronage differentially refrain from participation, allowing the electorate and party organizations to be dominated by poorer voters. But this may only reinforce politicians’ incentives against making policy appeals, stalling emergence of more policy-based electoral competition even as the middle class grows.

African democracies are increasingly urban. While ethnicity is generally correlated with vote choice, recent research suggests there may be less ethnic voting in cities. But I show that voting for ethnically-affiliated parties is as common in some neighborhoods in urban Ghana as in rural areas, while virtually non-existent in other neighborhoods elsewhere within the same city. This intra-urban variation is not explained by differences in the salience of ethnic identities or other individual-level characteristics of voters themselves. Instead, it is influenced by the diversity and wealth of the local neighborhoods in which parties and voters interact. These neighborhood characteristics change otherwise similar voters’ expectations of the benefits they will receive from an ethnically-affiliated party when living in different places, producing intra-urban differences in the importance of ethnicity for vote choice.

Do street-level bureaucrats discriminate in the services they provide to constituents? We use a field experiment to measure differential information provision about voting by local election administrators in the United States. We contact over 7,000 election officials in 48 states who are responsible for providing information to voters and implementing voter ID laws. We find that officials provide different information to potential voters of different putative ethnicities.  Emails sent from Latino aliases are significantly less likely to receive any response from local election officials than non-Latino white aliases and receive responses of lower quality. This raises concerns about the effect of voter ID laws on access to the franchise and about bias in the provision of services by local bureaucrats more generally.

Theories of instrumental ethnic voting in new democracies propose that voters support co-ethnic politicians because they expect politicians to favor their co-ethnics once in office.  But many goods that politicians deliver to voters are locally non-excludable in rural areas, so the local presence of an ethnic group associated with a politician should affect a rural voter’s assessment of how likely she is to benefit from that politician’s election. Using geocoded polling station-level election results alongside survey data from Ghana, we show that otherwise similar voters are less likely to vote for the party of their own ethnic group, and more likely to support a party associated with another group, when the local ethnic geography favors the other group.  This result helps account for the imperfect correlation between ethnicity and vote choice in African democracies. More generally, this demonstrates how local community and geographic contexts can modify the information conveyed by ethnicity and influence voter behavior.

We consider the effect of legislative primaries on the electoral performance of political parties in a new democracy.  While existing literature suggests that primaries may either hurt a party by selecting extremist candidates or improve performance by selecting high valence candidates or improving a party’s image, these mechanisms may not apply where clientelism is prevalent.  A theory of primaries built on a logic of clientelism with intra-party conflict instead suggests different effects of legislative primaries for ruling and opposition parties, as well as spillover effects for presidential elections.  Using matching with an original dataset on Ghana, we find evidence of a primary bonus for the opposition party and a primary penalty for the ruling party in the legislative election, while legislative primaries improve performance in the presidential election in some constituencies for both parties.

In new democracies, why do political party leaders relinquish power over nominations and allow legislative candidates to be selected by primary elections? Where the legislature is weak and politics is clientelistic, democratization of candidate selection is driven by local party members seeking benefits from primary contestants. Analysis of an original dataset on legislative nominations and political interference by party leaders for the 2004 and 2008 elections in Ghana shows that primaries are more common where nominations attract more aspirants and where the party is more likely to win, counter to predictions in existing literature. Moreover, the analysis shows that party leaders interfere in primaries in a pattern consistent with anticipation of party members’ reactions.

Primary elections in advanced democracies are usually conceptualized as institutions that generate nominees that have higher valence – better campaigning skills and popularity within the party – at the potential cost of being more ideologically extreme. But spatial models of primary elections are inappropriate for new democracies, where there is often little ideological competition in elections. We identify key imperatives that shape the decisions of party leaders in new democracies when choosing among different candidate selection mechanisms: the need to prevent elite defections and to motivate grassroots activists. We explore this argument in Ghana, a new democracy in which both major parties have gradually adopted and adapted primaries to select legislative candidates. Ghana’s experience with primaries highlights the central role that candidate selection institutions play in the development of political parties in new democracies.

Ichino, Nahomi and Noah L Nathan. Working Paper. “Democratizing the Party: The Effects of Primary Election Reforms in Ghana.” Revise and resubmit.

Recent reforms to primary election rules by one of Ghana’s major parties offer a rare opportunity to assess the effects of expansions of the franchise in contemporary new democracies, where universal suffrage was usually otherwise already established at independence. We propose that democratizing candidate selection by expanding the primary electorate has two consequences in patronage-oriented political systems: the electorate will have more diverse preferences and vote buying will become a less effective strategy. These changes, in turn, affect the types of politicians who seek and win legislative nominations. Using an original dataset on candidate entry and nominations, we show that expanding the primary electorate opened paths to office for politicians from social groups that were previously excluded, including women and members of ethnic groups outside a party’s core national coalition.

Brierley, Sarah and Noah L Nathan. Working Paper. “The Connections of Party Brokers.”

Seminal models of clientelism assert that parties value brokers for their strong downward ties to voters. Despite its dominance, scholars have not empirically scrutinized key assumptions of this theory due to the challenges of measuring brokers’ network connections. We analyze unique data from three sources – Ghana’s voter register, a handmade catalogue of local elites, and a large-scale survey of aspiring party brokers. We show that the observable implications of the standard model do not hold: brokers know surprisingly few voters, brokers with more downward connections are not the most active or effective, and parties do not select the brokers who know the most people. Instead, brokers with the most upward connections to local elites appear to be the most valuable to parties. We build inductively from these results to develop an alternative theory of brokers, proposing that many parties value “problem solvers” over “monitors.”
