Housing vouchers provide critical assistance to low-income renters, but roughly 40% of vouchers go unused, in part due to difficulty finding landlords to accept them. Vincent Reina shares findings from a pilot program that instead gives cash assistance directly to tenants.Abstract: This article examines a new rental assistance program in Philadelphia, called PHLHousing+, that disburses unconditional cash payments directly to tenants to eliminate their housing cost burden. The program is designed as a 2.5-year randomized controlled trial that aims to test the impact of direct- to-tenant cash assistance on household outcomes compared with traditional housing vouchers. The motivations for the program range from the need for more flexible tools that respond to the diverse needs of low-income renters to the desire for a robust evidence base on effective policies to improve household outcomes. The article also discusses the evolution of the idea behind PHLHousing+ before the COVID-19 pandemic through to its development, using knowledge obtained from upscaling local pandemic emergency rental assistance programs. Finally, the article describes the program’s implementation, including participant enrollment, strategies to minimize benefits loss, and cash disbursement mechanisms. It reflects on the lessons learned throughout this process, such as the importance of flexible funding and a strong research-practice partnership. The goal is to provide guidance to those planning similar programs and inform local and national policy, especially on direct-to-tenant, cash-based housing assistance.Show notes:Reina, V., Fowle, M., Jaffee, S., Mulbry, R., & Fortenberry, M.

Seattle’s low-rise multifamily zones have produced more than 20,000 townhomes over the past 30 years.

Rob Collinson, an Assistant Professor of Economics at the University of Notre Dame, dives into the complexities of the Housing Choice Voucher program. He discusses the gap between eligible households and those receiving assistance, advocating for reforms to maximize its impact. The conversation explores how housing voucher design influences rent and neighborhood quality, with insights into the challenges landlords face and the critical need for effective tenant counseling. Collinson also sheds light on the implications of recent policy shifts on opportunity for low-income families.

Shared micromobility programs offering scooters and bikes have exploded across the US in recent years, but the benefits haven't been shared evenly.

Do people drive less because they live in buildings that don’t provide parking, or do they live in buildings that don’t provide parking because they drive less? That question has huge implications for how we build and rebuild our cities, yet researchers have struggled for decades to answer it conclusively. UCLA professor Adam Millard-Ball joins us to discuss new research that finally — we hope — puts the question to bed. Taking advantage of San Francisco’s affordable housing lottery, Millard-Ball and colleagues find that (as-good-as-)randomly assigning tenants to different buildings and neighborhoods has substantial impacts on their transportation choices, with lower parking ratios resulting in less driving and more transit use. We talk about what this means for housing and parking policy, and what it says about the behavioral shifts needed to make cities more affordable, accessible, and sustainable.Show notes:Millard-Ball, A., West, J., Rezaei, N., & Desai, G.

Many studies have looked at the effects of new transit infrastructure on housing prices, gentrification, and other neighborhood changes. But how does housing policy — specifically rising rents and worsening affordability — affect transit?
