# Evolutionarily Stable (Mis)specifications: Theory and Applications

@article{He2021EvolutionarilyS, title={Evolutionarily Stable (Mis)specifications: Theory and Applications}, author={Kevin He and Jonathan Libgober}, journal={Proceedings of the 22nd ACM Conference on Economics and Computation}, year={2021} }

We introduce an evolutionary framework to evaluate competing (mis)specifications in strategic situations, focusing on which misspecifications can persist over a correct specification. Agents with heterogeneous specifications coexist in a society and repeatedly match against random opponents to play a stage game. They draw Bayesian inferences about the environment based on personal experience, so their learning depends on the distribution of specifications and matching assortativity in the…

Which Misperceptions Persist?

- Economics

We use an evolutionary model to determine what sorts of misperceptions are likely to persist. In our model, every period a new generation of agents uses their subjective models and the outcome…

We study how a misspecified agent learns from endogenous data when their prior belief does not impose restrictions on the distribution of outcomes, but can assign probability 0 to a neighborhood of…

We use an evolutionary model to determine which misperceptions can persist. Every period, a new generation of agents use their subjective models and the data generated by the previous generation to…

Competing Models

- 2021

A model in which different agents compete to predict a variable of interest, related to observables via an unknown data generating process, is developed and it is shown that it crucially depends on the size of the dataset.

Learning from Shared News: When Abundant Information Leads to Belief Polarization

It is shown that beliefs can diverge in this environment leading to polarization, and news aggregators can curb polarization caused by shared news.

Welfare Comparisons for Biased Learning∗

We study robust welfare comparisons of learning biases, i.e., deviations from correct Bayesian updating. Given a true signal distribution, we deem one bias more harmful than another if it yields…

Learning from Shared News:

We study learning via shared news. Each period agents receive the same quantity and quality of first-hand information and can share it with friends. Some friends (possibly few) share selectively,…

Pathwise Concentration Bounds for Misspecified Bayesian Beliefs

We show that the probability that Bayesian posteriors assign to the outcome distributions that do not ``best fit'' the empirical distribution in terms of Kullback-Leibler divergence converges to zero…

Berk-Nash Equilibrium: A Framework for Modeling Agents with Misspecified Models

- Economics
- 2014

An equilibrium framework that relaxes the standard assumption that people have a correctly-specified view of their environment and introduces the notion of a Berk-Nash equilibrium, where each player follows a strategy that is optimal given her belief, and her belief is restricted to be the best fit among the set of beliefs she considers possible.

This paper explores a form of bounded rationality where agents learn about the economy with possibly misspecified models. I consider a recursive general-equilibrium framework that nests a large class…

Stability and Robustness in Misspecified Learning Models

An approach to analyze learning outcomes in a broad class of misspeciﬁed environments, spanning both single-agent and social learning, and provides general criteria to determine when beliefs in a given environment converge to some long-run belief either locally or globally.

Biased-Belief Equilibrium

This work investigates how distorted, yet structured, beliefs can persist in strategic situations and imposes a mild monotonicity restriction on the feasible biased beliefs, and gets sharp predictions and novel insights into the set of stable outcomes and their supporting stable biases in various classes of games.
