Property taxes, wealth inequality, and economic activity: lessons from São Paulo, Brazil

As wealth inequality continues to grow around the world, and as economic activity is increasingly geographically concentrated, there are wide-ranging debates in the economic literature about the role tax policy should play in promoting more equitable distribution of wealth and opportunity. In many rich countries, property taxes represent one of the most prominent tools for raising revenue and incentivizing economic activity in one location versus another. However, since property taxes are rarely used in low- and middle-income countries (LMICs), there is a gap in our understanding of how effectively they might work to affect disparities and economic activity in different contexts. 

Brazil offers a unique case study for examining the role property taxes can play in reducing both geographic and racial wealth disparities in an LMIC context. With a robust data infrastructure for researchers to draw upon, and a recent tax reform aimed at creating more equitable distribution of economic activity, the country presents an opportunity to deepen our understanding of how individuals and firms respond to taxation and how taxation on high-value property can act as a tool for redirecting economic activity and promoting greater racial equity. Supported by O-Lab’s Place-Based Policy Initiative, Javier Feinmann, a PhD candidate in Economics, and his collaborators Roberto Hsu Rocha, Davi Moura, and Thiago Scott, are investigating these questions, drawing upon a rich dataset from the city of São Paulo. 

In the first stage of his research, Feinmann and his team are working to understand existing racial and gender disparities in wealth and property ownership in São Paulo. The researchers’ work is supported by a wealth of administrative data that allows him to create highly granular maps of property ownership and property tax rates. The project’s starting point is a database on annual property assessments in São Paulo. Using location-specific property identifiers, the team can spatially plot property values and tax rates throughout the city. Then, using a separate dataset which includes demographic information, they can link these properties to their owners, allowing race and gender identifiers to be incorporated into the map.

In this descriptive stage of his project, Javier and the team have confirmed disparities in property ownership for women and minority groups. In particular, the researchers find that across all property types and regions of São Paulo, women own fewer properties than men. The team has also found substantial racial disparities in property ownership; however, these are more variable across different regions of the city – likely resulting from existing regional segregation. In general, these gaps in gender and racial ownership are more pronounced among high-value properties.

In the next stage of his project, Feinmann will take a few extra steps to paint a more detailed picture of the distribution of property wealth and tax burdens in São Paulo. Specifically, since the state of São Paulo publicizes the registration of all businesses, Javier and coauthors are able to track the ultimate owners of registered firms that own property in São Paulo, including owner demographics. Then, the property wealth owned by firms can be proportionally assigned to ultimate owners. This novel approach provides a more comprehensive picture of who owns what in São Paulo. By accounting for individuals who own real estate through firms, this project also makes an important contribution to contemporary conversations by economists including Gabriel Zucman and Emmanuel Saez on how to accurately measure wealth held by the top percentiles.

Going forward, the researchers will use their findings as a basis for an analysis of how a major 2014 property tax reform in São Paulo affected economic activity and firm behavior in the city. The law in question divided São Paulo into three separate fiscal zones, and revised the property tax assessment formula to increase taxes on properties closest to the city’s wealthy central district. The intention of this change was to more equitably distribute property tax burdens in São Paulo – was the policy successful? What were the policy’s consequences for the location of economic activity – did it incentivize firm creation in less affluent, low-tax areas, or purely encourage existing firms to relocate? Upcoming stages of this project will explore these questions, and produce important new evidence on how regionally-targeted tax policies can influence racial and gender disparities in property ownership and wealth.

How does increased minority enfranchisement impact public finance, preferences for public goods, and government fragmentation?

In 2013, the US Supreme Court issued a controversial ruling in the case of Shelby County v Holder, severely limiting the power of the federal government to enforce provisions of the 1965 Voting Rights Act (VRA). Before the ruling, changes to voting regulations by certain state and local governments were required to be “pre-cleared,” or deemed nondiscriminatory, before they were allowed to go into effect; after the ruling, it became the responsibility of disenfranchised voters to advocate for themselves and demonstrate that changes to voting laws were discriminatory. 

This landmark ruling inspired a series of new studies examining the historical impacts of the VRA, in an effort to better understand its consequences and forecast the potential impacts of the Shelby decision. Raheem Chaudhry, a PhD candidate at the Goldman School of Public Policy, is leading one such study through his participation in the O-Lab’s Initiative on Racial Equity in the Labor Market.

Map of counties covered by special provisions of the Voting Rights Act, and their uncovered neighbors.

Raheem’s research focuses on how the VRA impacted local and state revenues, as well as municipal spending on a variety of services and programs – hypothesizing that higher turnout among Black voters would lead to increased spending on public goods. Raheem used data from the Census of Governments, a survey conducted every five years, to get a detailed picture of government spending at all levels, including cities, counties, and special districts. He then compared jurisdictions covered by special provisions of the VRA that applied to only especially discriminatory districts to similar, geographically-adjoined districts, in order to isolate the impact of these parts of the Act. Subsequently, he was able to compare differences in spending in districts impacted to those unaffected.

Initially, Raheem expected to find increases in public spending in those jurisdictions with substantial Black populations that were identified by the VRA as particularly discriminatory (those required to pre-clear any future changes to voting laws). In actuality, he found that counties with larger non-white population shares demonstrated relative declines in government revenues and expenditures — but why? Raheem’s working theory, informed in part by existing literature, sees these changes as a response to increased integration. By ruling out tax base changes as the cause of declining public spending — there were no significant changes in home values or incomes during the period of study — Chaudhry’s work offers a compelling narrative that voters in these districts were less inclined to finance increasingly integrated public resources. Further evidence in support of this theory can be seen in decreased levels of public school enrollment, particularly among white students, from 1968 to 1972 – which suggests that families turned to private school in response to increased integration. Raheem also found relative increases in government fragmentation amongst counties targeted by special provisions of the VRA with larger non-white populations. This finding follows existing literature, and suggests a mechanism by which increasingly integrated counties sought to maintain local control over public finances.

Raheem’s project complements a growing body of work among economists that shows the  limits to migration as a tool for surmounting racial income inequality. His work adds an important focus, however, on the role of political power in the success or failure of policies promoting access to resources such as education, transportation, and more. “I think the way that people traditionally think about this is, ‘How do we move kids to high opportunity areas?’ But you can also think about, ‘How do you transform the places kids already live?’ And one way you can do that is through the political process.” While Chaudhry’s project does not find an explicit positive impact of the VRA on local public spending, it nevertheless has important lessons for policymakers. In particular, his work shows the powerful way in which racial backlash can undermine efforts to more equitably allocate public resources.
