The Roots of ‘Bubbly’ Recessions
A downturn following the collapse of an asset bubble ? an episode of speculative booms in asset prices ? can be severe and sustained, with output and employment often lower than in the prebubble economy. This Economic Brief considers some possible theoretical explanations. It argues, based on insights from a simple economic model, that the interaction among financial frictions, wage rigidity, and the constraints of monetary policy near the zero lower bound is a key source of inefficiency in large bubbles. One potential remedy is to regulate speculative investment on bubbly assets so that ...

How Does Market Competition Affect Banks' Adaptation to Changes in Flood Risks?
This article examines the interplay between market competition and banks' strategic responses to projected long-term changes in flood risks, using data from the home-equity credit market post-Hurricane Harvey. Our work reveals that banks updated their risk models based on exposure to the hurricane, with those in competitive markets less likely to adopt cautious lending practices. It also explores the concept of strategic complementarity, showing that banks' adaptive behaviors are influenced by their competitors. These findings shed insights on how market forces may influence the way banks ...

Leveraging the Disagreement on Climate Change: Theory and Evidence
We theoretically and empirically investigate how climate risks affect collateralized debt markets. First, we develop a debt model where agents have different beliefs over a long-run risk. In contrast with existing two-period competitive-equilibrium models, our infinite-horizon competitive-search model predicts more pessimistic agents are more likely to make leveraged investments on risky collateral assets. They also tend to use longer maturity debt contracts, which are more exposed to the long-run risk. Second, employing large data on real estate and mortgage transactions, combined with high ...

Charting the Course: How Does Information about Sea Level Rise Affect the Willingness to Migrate?
An important yet less studied factor in determining the extent of adaptation to climate change is information: are people adequately informed about their vulnerability to future climate-related risks, and does their willingness to adapt depend on this knowledge? Focusing on how communication about projected sea level rise (SLR) affects the willingness to migrate, we implemented a large randomized control survey experiment with a nationally representative sample of more than 7,000 respondents across all provinces in Vietnam. We randomly assign respondents to different information treatments. ...

Are Some Homebuyers Strategically Transferring Climate Risks to Lenders?
Recent empirical research suggests that certain homebuyers may be strategically transferring climate risks to banks via the mortgage market, and banks may be transferring such risks to government-sponsored enterprises via securitization. The evidence highlights the nuanced ways in which participants in the financial markets strategically adapt to climate change.

Assessing GSE Mortgage Portfolios’ Exposure to Past and Future Flood Risk
This article evaluates the exposure of government-sponsored enterprises' (GSEs) mortgage portfolios to flood risks as projected by the First Street Foundation and analyzes the realized impact of Hurricane Irma on mortgage defaults. The analysis leverages extensive GSE data spanning from 1999 to 2023 and utilizes risk projections through 2050 to provide a comprehensive view of both potential future risks and actual past outcomes.

Time-Varying Skewness and Real Business Cycles
In the context of a quantitative real business cycle (RBC) model, we document that shocks to the higher-order moments, especially the skewness, of productivity can have large first-order effects on business cycles. We augment a standard small open economy RBC model with a new feature: a discrete regime switching between higher-order moments of total factor productivity shocks between an unrest state and a quiet state. To map the theory to data, we exploit an extensive database of mass political unrest around the world. We calibrate the model to the observed increases in the volatility and ...

The Impact of Higher Temperatures on Economic Growth
What happens to the economy when it gets hot outside? Despite long-standing assumptions that economic damage from rising global temperatures would be limited to the agricultural sector or developing economies, this Economic Brief presents evidence that higher summer temperatures hurt a variety of business sectors in the United States
