Panel Experiments and Dynamic Causal Effects: A Finite Population Perspective
By: Iavor Bojinov, Ashesh Rambachan and Neil Shephard
In panel experiments, we randomly assign units to different interventions, measuring their outcomes, and repeating the procedure in several periods. Using the potential outcomes framework, we define finite population dynamic causal effects that capture the relative... View Details

By: Matteo Gasparini, Matthew C. Ives, Ben Carr, Sophie Fry and Eric Beinhocker
Investments via the financial system are essential for fostering the green transition. However, the role of existing financial regulations in influencing investment decisions is understudied. Here we analyse data from the European Banking Authority to show that... View Details

Delayed-Response Strategies in Repeated Games with Observation Lags
By: Drew Fudenberg, Yuhta Ishii and Scott Duke Kominers
We extend the folk theorem of repeated games to two settings in which players' information about others' play arrives with stochastic lags. In our first model, signals are almost-perfect if and when they do arrive, that is, each player either observes an almost-perfect... View Details

International Evidence on the Effects of a Local Presence by U.S. Credit Rating Agencies
By: Liran Eliner, Michael Machokoto and Anywhere Sikochi
Major U.S. credit rating agencies are criticized for failing to understand developments in other economies and thereby impeding capital access by assigning lower ratings. Consistent with this, we find that Moody's and S&P credit ratings are more favorable after the... View Details

Entrepreneurship as Experimentation
By: William R. Kerr, Ramana Nanda and Matthew Rhodes-Kropf
Entrepreneurship research is on the rise but many questions about its fundamental nature still exist. We argue that entrepreneurship is about experimentation: the probabilities of success are low, extremely skewed and unknowable until an investment is made. At a macro... View Details

Ensembles of Overfit and Overconfident Forecasts
By: Y. Grushka-Cockayne, V.R.R. Jose and K. C. Lichtendahl
Firms today average forecasts collected from multiple experts and models. Because of cognitive biases, strategic incentives, or the structure of machine-learning algorithms, these forecasts are often overfit to sample data and are overconfident. Little is known about... View Details

Populism and the Return of the 'Paranoid Style': Some Evidence and a Simple Model of Demand for Incompetence as Insurance against Elite Betrayal
By: Rafael Di Tella and Julio J. Rotemberg
We present a simple model of populism as the rejection of “disloyal” leaders. We show that adding the assumption that people are worse off when they experience low income as a result of leader betrayal (than when it is the result of bad luck) to a simple voter choice... View Details

Paying (for) Attention: The Impact of Information Processing Costs on Bayesian Inference
By: Scott Duke Kominers, Xiaosheng Mu and Alexander Peysakhovich
Human information processing is often modeled as costless Bayesian inference.
However, research in psychology shows that attention is a computationally costly and potentially limited resource. We study a Bayesian individual for whom computing posterior beliefs is... View Details
