Riskless interest rates fell in the wake of the financial crisis and have remained low. We explore a simple explanation: This recession was perceived as an extremely unlikely event before 2007. Observing such an episode led all agents to re-assess macro risk, in particular, the probability of...

Behavioral economists have recently put forth a theoretical explanation for the equity premium puzzle based on combining myopia and loss aversion. Complementing the behavioral theory is evidence from laboratory experiments, which provide strong empirical support consistent with myopic loss...

How accurate are older people's expectations about their future Social Security benefits? Using panel data from the Health and Retirement Study, we compare respondents' observed Social Security claiming ages and benefits with subjective expectations provided during their 50s and early 60s. We...

Matched transaction-level, credit-registry, and survey-based data reveal that consumers on average form excessively high (low) income expectations relative to ex-post realizations after unexpected positive (negative) income shocks. These extrapolative income expectations lead consumers to...

How should industrial policies be directed to reduce distortions and foster economic development? We study this question in a multi-sector model with technology adoption, where the production of goods and modern technologies features rich network structures. We provide simple formulas for the...

We analyze how output and wages behave under different scenarios for technological progress that may culminate in Artificial General Intelligence (AGI), defined as the ability of AI systems to perform all tasks that humans can perform. We assume that human work can be decomposed into atomistic...

This paper examines the impact of roads on structural transformation and business composition theoretically and empirically. We develop a two-sector model of regional trade with endogenous firm entry that highlights two opposing forces. \textit{Ceteris paribus} lower trade costs in...

Women's contribution to the economy has been markedly underestimated in predominantly agricultural societies, due to their widespread involvement in unpaid agricultural work. Combining data from the US Census and several early sources, we create a consistent measure of male and female employment...

To fill the knowledge gap that previous studies ignore either housing or internal urban structure and to enable better fit with important stylized facts, we construct a two-sector optimal growth model of housing where housing is produced by land and housing structure/household durables. We...

Transformative technologies like generative artificial intelligence promise to accelerate productivity growth across many sectors, but they also present new risks from potential misuse. We develop a multi-sector technology adoption model to study the optimal regulation of transformative...
