A Q-theory of Banks

Juliane Begenau, Saki Bigio, Jeremy Majerovitz, and Matias Vieyra

Bank capital requirements are based on book values, which are slow to reflect losses. In this paper, we develop a dynamic model of banks to study the interaction of regulation and delayed accounting. Our model explains four stylized facts: book and market values diverge during crises, the market-to-book ratio predicts future profitability, book leverage constraints rarely bind strictly even as market leverage fans out during crises, and banks delever gradually after net-worth shocks.

Pareto Improvements in the Contest for College Admissions

Kala Krishna, Sergey Lychagin, Wojciech Olszewski, Ron Siegel, and Chloe Tergiman

Many countries base college admissions on a centrally-administered test. Students invest a great deal of resources to improve their performance on the test, and there is growing concern about the high costs associated with these activities. We consider modifying the test by introducing performance-disclosure policies that pool intervals of performance rankings. Pooling affects the equilibrium allocation of students to colleges, which hurts some students and benefits others, but also affects students’ effort.

How Important Is Health Inequality for Lifetime Earnings Inequality?

Roozbeh Hosseini, Karen Kopecky, and Kai Zhao

Using a dynamic panel approach, we provide empirical evidence that negative health shocks significantly reduce earnings. The effect is primarily driven by the participation margin and is concentrated among the less educated and those in poor health. Next, we develop a life cycle model of labor supply featuring risky and heterogeneous frailty profiles that affect individuals’ productivity, likelihood of access to social insurance, disutility from work, mortality, and medical expenses.

Efficient Conservation of the Brazilian Amazon: Estimates from a Dynamic Model

Rafael Araujo, Francisco Costa, and Marcelo Sant'Anna

This paper estimates the Brazilian Amazon’s carbon-efficient forest cover – i.e. when farmers internalize the social cost of carbon. We propose a dynamic discrete choice land-use model and estimate it using a panel of land use and carbon stock of 5.7 billion pixels between 2008 and 2017. The business-as-usual scenario implies an inefficient release of 42 billion tons of CO2 in the long run resulting from the deforestation of an area twice the size of France.

Barriers to Entry and Regional Economic Growth in China

Loren Brandt, Gueorgui Kambourov, and Kjetil Storesletten

Labor productivity in manufacturing differs starkly across regions in China. We document that productivity, wages, and start-up rates of non-state firms have nevertheless experienced rapid unconditional regional convergence after 1995. To analyze these patterns, we construct a Hopenhayn (1992) model that incorporates location-specific capital wedges, output wedges, and entry barriers. Using Chinese Industry Census data we estimate these wedges and examine their role in explaining differences in performance and growth across prefectures.

Retractions: Updating from Complex Information

Duarte Gonçalves, Jonathan Libgober, and Jack Willis

We modify a canonical experimental design to identify the effectiveness of retractions. Comparing beliefs after retractions to beliefs (a) without the retracted information and (b) after equivalent new information, we find that retractions result in diminished belief updating in both cases. We propose this reflects updating from retractions being more complex, and our analysis supports this: we find longer response times, lower accuracy, and higher variability.

Attention Utility: Evidence From Individual Investors

Edika Quispe–Torreblanca, John Gathergood, George Loewenstein, and Neil Stewart

We study attention utility, the hedonic pleasure or pain derived purely from paying attention to information, which differs from the news utility that arises from gaining new information. The main, field, study examines brokerage account login data to show that investors pay disproportionate attention to already-known positive information on their stocks. Through its effect on logins, this selective attention affects their trading activity.

``Many networks naturally form as people come together to form subgraphs, e.g. as coauthors of a paper, or other teams. This is the basis for a new, computationally tractable method of estimating network formation."
