Our analysis reveals that the use of private pools, while improving blockspace allocation efficiency, negatively impacts price discovery. We show that the presence of private pools limits the amount of information revealed through pending orders and increases the execution risk of informed orders. We argue that price discovery can be improved by increasing the number of validators monitoring private pools or the block production rate on the chain.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.

This paper shows the result of a communication experiment in an online environment. For six consecutive terms, the instructor taught Introduction to Statistics. The instructor added a more direct communication strategy during two of those five terms. She used weekly communications that linked course material with events discussed by students previously and a personal message to each student. The intervention resulted in improved learning, measured by better grades, and more enjoyment of the course, measured using student comments in teaching evaluations.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.

We find an average learning loss of 0.14 SD in math and 0.05 SD in reading. The pandemic widened preexisting gaps by socioeconomic status (SES): students in the bottom quintile of SES learned 0.21 SD less in math and 0.10 SD less in reading. Learning losses for immigrant students in math are larger than those for native ones. We do not find economically significant differences by gender.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.

We study this in the context of 2017 Baltimore. We find that households exposed to incarceration have lower levels of income and wealth and that these differences are largest for White households. Additionally, we find that Black households without incarceration exposure fare no better in household income than White households with exposure but have higher levels of wealth (driven by lower debt levels). These results highlight the importance of studying the relationship between the criminal legal system and economic inequality.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.

Inflation uncertainty has increased significantly since the start of 2021, even as a similar measure of sales uncertainty has declined. We also find large cross-sectional differences in inflation uncertainty, with uncertainty particularly elevated for smaller firms and those in the goods sector. Finally, we show that firms that are more uncertain about their own price expectations experience higher forecast errors 12 months later. These findings suggest that inflation uncertainty may be important for understanding firm performance.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.

While the surveys differ in how comprehensively they measure WFH, they are highly correlated in the cross section of US states, suggesting that they will yield similar causal effects. Researchers should carefully consider the trade-off between how comprehensively WFH is measured and measurement error, with the American Community Survey well suited for low levels of aggregation and the Survey of Working Arrangements and Attitudes and Real-Time Population Survey well suited to measuring distinct types of WFH. We also document that the experimental 2020 ACS replicate weights produce errors that are too small.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.

Dominant companies that are disproportionately active in the corporate control market for start-ups have become more insulated from the pressures of product market competition over the same period. These facts are consistent with the hypothesis that start-up acquisitions have contributed to rising oligopoly power.","PeriodicalId":72114,"journal":{"name":"AEA papers and proceedings.
