"Consumers’ perceptions of current inflation play a key role in understanding household consumption and investment decisions as well as the impact of monetary policies. Evidence from countries with low or moderate inflation shows that people’s perception of inflation often diverges significantly and systematically from official inflation rates. We examine the relationship between actual and perceived inflation in a hyperinflation environment, and compare it to the corresponding relationships in low and moderate inflation regimes. Our experimental results show that, opposite to low inflation, hyperinflation is greatly underestimated in people’s perceptions. Moreover, the accuracy of inflation perceptions, as inflation rises, exhibits an inverse-U shape, which confirms our novel, preregistered “Perception Accuracy Inversion” hypothesis."

"This paper investigates the gender differences in two types of overconfidence: overestimation and overplacement. We aggregate findings from 39 experimental studies in economics, published between 2000-2020 – all of which employed real-effort tasks – in a preregistered Bayesian hierarchical analysis. A previous meta-study by Bandiera et al. (2022) concluded that both men and women exhibit overconfidence, with no significant gender differences. However, Moore and Healy (2008) define multiple types of overconfidence, which are sometimes inversely related. Following their terminology, we divide our meta-study sample into two categories – overestimation and overplacement – and test whether the original results still hold. We motivate the division into subsamples with a theoretical argument, which shows that the relationship of the two types of overconfidence is not necessarily fixed. In the overall sample, we find evidence of overconfidence among men but not among women; however, the difference in the magnitude of their biases is not statistically significant. In the subsamples, there is no strong evidence that either men or women exhibit significant overestimation or overplacement, nor are there significant gender differences in the magnitude of these biases for either type of overconfidence."

"This preregistered study investigates how individuals’ perceptions and expectations of inflation respond to informational interventions (e.g. current inflation rate) across three inflationary contexts: low, intermediate, and high. We hypothesize that the impact of an informational intervention on both inflation perceptions and expectations is strongest during periods of low inflation and diminishes as inflation rises, particularly under hyperinflation. To test this, we conduct an online experiment with representative samples from the UK, Egypt, and Argentina, measuring both inflation literacy and the effect of the information treatment on predictions. The findings partially support this hypothesis such that interventions exert the strongest influence in low inflation environments, a weaker effect in intermediate inflation contexts, and a more complex pattern in high inflation environments, where prior beliefs remain influential but treatments shape expectations. These results demonstrate that the effectiveness of information treatments varies with the inflationary environment and reflect the complex ways in which individuals form beliefs under different economic conditions."

"This study focuses on the psychological and social drivers of cryptocurrency investment, particularly peer influence and fear of missing out (FoMO). We ask to what extent does FoMO affect individuals’ decisions to enter the asset markets? We develop a theoretical model of fear of missing out (FoMO) in asset trading, in which agents’ decision utility is driven by anticipated regret and peer behavior. To test the predictions of our model, we design an experiment in which participants make market entry decisions anticipating feedback about peer behavior and outcomes."
