The Effect of Rising Insurance Premiums on Mortgage Delinquency and Household Relocation
U.S. homeowners' insurance premiums have increased drastically, widely attributed to climate risk. Using household-level microdata and two novel instruments, we document three findings. First, households facing larger premium increases are more likely to relocate, moving to areas with lower climate risk and insurance costs. Homes with larger increases are more often acquired by investors, who obtain lower premiums. Second, higher premiums increase mortgage delinquencies. Third, the relocation effect is stronger among less financially constrained households, while the delinquency effect ...

Climate Risk, Insurance Premiums and the Effects on Mortgage and Credit Outcomes
As climate change exacerbates natural disasters, homeowners’ insurance premiums are rising dramatically. We examine the impact of premium increases on borrowers’ mortgage and credit outcomes using new data on home insurance policies for 6.7 million borrowers. We find that higher premiums increase the probability of mortgage delinquency, as well as prepayment (driven mainly by relocation). The results hold using a novel instrumental variable. The delinquency effect is greater for borrowers with higher debt-to-income ratios. Both delinquency and prepayment effects are present in both GSE ...

Last Resort Insurance: Wildfires and the Regulation of a Crashing Market
An increasing number of people are denied home insurance coverage in the private market and must instead turn to state-sponsored plans known as “Insurers of Last Resort.” This paper examines how insurers of last resort interact with the private market under increasing disaster risks. We first present a simple model of an adversely selected insurance market, highlighting that the insurer of last resort allows strict price regulation to be compatible with full insurance. We then empirically study the California non-renewal moratoriums, a regulation that forced insurers to supply insurance ...

Wildfires and Real Estate Values in California
Wildfires have been a concern in California for decades. The intensity of these events has increased recently, with particularly large and destructive fire seasons between 2018 and 2021. Analysis shows that distance from high fire-risk zones had little impact on residential housing values in the past. However, that has changed since the late 2010s, coinciding with more extensive fire damage to land and structures across the state. Insurance availability appears to help little in preserving home values in areas that are considered more at risk.

A Denial a Day Keeps the Doctor Away
Who bears the consequences of administrative problems in healthcare? We use data on repeated interactions between a large sample of U.S. physicians and many different insurers to document the complexity of healthcare billing, and estimate its economic costs for doctors and consequences for patients. Observing the back-and-forth sequences of claim denials and resubmissions for past visits, we can estimate physicians’ costs of haggling with insurers to collect payments. Combining these costs with the revenue never collected, we estimate that physicians lose 18% of Medicaid revenue to billing ...

Financial Incentives, Hospital Care, and Health Outcomes: Evidence from Fair Pricing Laws
It is often assumed that financial incentives of healthcare providers affect the care they deliver, but this issue is surprisingly difficult to study. The recent enactment of state laws that limit how much hospitals can charge uninsured patients provide a unique opportunity. Using an event study framework and panel data from the Nationwide Inpatient Sample, we examine whether these regulations lead to reductions in the amount and quality of care given to uninsured patients. We find that the introduction of a fair pricing law leads to a seven to nine percent reduction in the average length of ...

What Explains the Decline in Life Insurance Ownership?
Life insurance ownership has declined markedly over the past 30 years, continuing a trend that began as early as 1960. In 1989, 77 percent of households owned life insurance (see figure 1). By 2013, that share had fallen to 60 percent. This article analyzes factors that might have contributed to the decline in life insurance ownership from 1989 to 2013. The focus of our analysis is on two broad sources of potential change in the demand for life insurance: changes in the socioeconomic and demographic characteristics of the population and changes in how those same characteristics are associated ...

The Growth and Challenges of Cyber Insurance
Cyberattacks have grown in frequency and cost over the past decade, with high-profile cases, such as the 2013 Target data breach, the 2017 Equifax data breach, and the leak of Democratic National Committee emails during the 2016 election making national headlines. Ransomware attacks, intellectual property theft, and fraud cost companies billions in recovery expenses, fines, and lost revenues every year. More firms are purchasing cyber insurance as a way to cover losses and expenses resulting from cyber incidents.

Catastrophe Bonds: A Primer and Retrospective
Since 1997, the catastrophe (CAT) bond market has provided the insurance industry with protections against natural disasters that have grown more frequent and costly. This article explains how CAT bonds work, and then looks at how the market for them has grown in size, coverage, and sophistication over the past two decades. It also explores how and why different types of institutions use CAT bonds to transfer insurance risks.
