Overview

I am on the 2021-2022 job market 

I am an applied microeconomist with research interests in real estate and household finance, environmental economics, urban economics, and public economics.  My research agenda focuses on understanding how households, insurers, lenders, and governments adapt to dynamic climate risk.

My job market paper studies how flood insurance pricing informs coastal homeowners about their risk and affects investment in risk-reducing adaptation.

  • Neglected No More: Housing Markets, Mortgage Lending, and Sea Level Rise (with Ben Keys)
    • Draft
    • Abstract: In this paper, we explore dynamic changes in the capitalization of sea level rise (SLR) risk in housing and mortgage markets. Our results suggest a disconnect in coastal Florida real estate: From 2013-2018, home sales volumes in the most-SLR-exposed communities declined 16-20% relative to less-SLR-exposed areas, even as their sale prices grew in lockstep. Between 2018-2020, however, relative prices in these at-risk markets finally declined by roughly 5% from their peak. Lender behavior cannot reconcile these patterns, as we show that both all-cash and mortgage-financed purchases have similarly contracted, with little evidence of increases in loan denial or securitization. We propose a demand-side explanation for our findings where prospective buyers have become more pessimistic about climate change risk than prospective sellers. The lead-lag relationship between transaction volumes and prices in SLR-exposed markets is consistent with dynamics at the peak of prior real estate bubbles.
  • What’s at Stake? Understanding the Role of Home Equity in Flood Insurance Demand (with Yanjun Liao)
    • Draft
    • Abstract: Millions of homeowners are exposed to increasing financial risk from natural disasters. Yet, many households are uninsured against the costliest disaster: flooding. We show that low home equity is an important driver of low flood insurance take-up. To isolate the causal effect of home equity on flood insurance demand, we exploit price changes over the housing boom and bust. Insurance take-up follows house price dynamics closely, with a home price elasticity around 0.3. Multiple mechanism tests suggest that mortgage default acts as implicit disaster insurance. As a result, households do not fully internalize their disaster risk.
