The adaptive learning approach has been fruitfully employed to model the formation of aggregate expectations at the … macroeconomic level, as an alternative to rational expectations. This paper uses adaptive learning to understand, instead, the … sentiment, defined as the degrees of excess optimism and pessimism that cannot be justified by the near-rational learning model …

study experimentally to what extent cross-game learning can reduce overbidding in SPAs, taking into account cognitive skills … losses from high bids are more salient than in SPAs. Experience in FPAs causes substantial cross-game learning for … bid shading by cognitively more able participants, resulting in lower profits in FPAs. Thus, cross-game learning has the …

infinite-horizon learning, and subjective expectations with Euler-equation learning. Under rational expectations, the model … necessitates of large, possibly unrealistically so, degrees of myopia. The same result persists under infinite-horizon learning …, given that agents are still remarkably farsighted. But, under Euler-equation learning, the model can fit the data with only …

We demonstrate that heat inhibits learning and that school air-conditioning mitigates this effect. Student fixed … heat being particularly damaging. Weekend and summer heat has little impact, suggesting heat directly disrupts learning … simple benefit-cost tests. Without air-conditioning, a 1°F hotter school year reduces that years learning by one percent. Hot …

Mortality and economic contraction during the 1918-1920 Great Influenza Epidemic provide plausible upper bounds for … outcomes under the coronavirus (COVID-19). Data for 43 countries imply flu-related deaths in 1918-1920 of 39 million, 2 …
