ALEXANDER SAHN

I am a political scientist currently working as a postdoctoral fellow at the Center for the Study of Democratic Politics at
Princeton University

My research seeks to understand and reduce racial inequalities in American political economy.

 

My dissertation shows how the interaction of individual attitudes and institutions in local governments in the US lead to land use policies responsible for the housing affordability crisis.

My work has been published in the American Political Science Review, Political Behavior, and Political Analysis.

RESEARCH

 

RACE AND REPRESENTATION IN CAMPAIGN FINANCE 2020. American Political Science Review (WITH JAKE GRUMBACH)

Campaign finance is more racially unequal than voter turnout or Congressional representation, but the nomination of candidates of color can close this gap.

Co-ethnic contributing behavior dominates co-gendered contributing with no evidence of intersectionality.

A large portion of observational studies would not meet statistical significance without undisclosed covariate adjustment.

Backlash to the Great Migration caused cities to adopt exclusionary zoning; today, the median large city allows apartments on only 12% of residential land.

FAUX-RESPONSIVENESS AND ELECTION CYCLES IN THE PERMITTING OF HOUSING

Cities permit less housing before elections when mayors are running for re-election, especially when homeowners dominate.

THE EFFECTIVENESS OF LOBBYING IN PUBLIC MEETINGS: EVIDENCE FROM SAN FRANCISCO

Attendees of public meetings (older, whiter, homeowners) get the outcomes they want (slowing and blocking affordable housing).

Gain-loss framing has little effect on problems and policy solutions, which have bipartisan support.

Co-ethnic contributing behavior dominates co-gendered contributing with no evidence of intersectionality.

A large portion of observational studies would not meet statistical significance without undisclosed covariate adjustment.

Variation in exclusionary zoning can be explained by a backlash to the Great Migration; today, the median large city allows apartments on only 12% of residential land.

THE EFFECTIVENESS OF LOBBYING IN PUBLIC MEETINGS: EVIDENCE FROM SAN FRANCISCO

Attendees of public meetings (older, whiter, homeowners) turn out more, get the outcomes they want (slowing and blocking nearby, affordable housing projects).

FAUX-RESPONSIVENESS AND ELECTION CYCLES IN THE PERMITTING OF HOUSING

Cities permit less housing before elections when mayors are running for re-election, especially when homeowners dominate.

RACIAL THREAT, GENTRIFICATION, AND POLICE CALLS FOR SERVICE (with Amy Lerman and Alyssa Mooney)

A substantial number of citizen-police interactions originate from calls for service, which increase as neighborhoods shift.

SCOPE CONDITIONS, NUMERACY, AND THE EVALUATION OF POLICY (with Amy Lerman and Laura Stoker)

Equivalency frames affect the public's evaluation of social problems, but gain-loss framing does not impact evaluation of potential solutions.

Application of IRT to crowdsourced labelled data combined with deep learning improves measurement of hate speech on social media
