Pricing via Artificial Intelligence : The Impact of Neural Network Architecture on Algorithmic Collusion
Zhang, Weipeng - 2023
Classic artificial intelligence (Q-learning) algorithms have been capable of consistently learning supra-competitive pricing strategies in infinitely repeated Nash-Bertrand pricing games without human communication. Such algorithms have been able to converge due to the temporal correlation of...

Grand Canonical Minority Game as a Sign Predictor
Wawrzyniak, Karol - 2014
In this paper the extended model of Minority game (MG), incorporating variable number of agents and therefore called Grand Canonical, is used for prediction. We proved that the best MG-based predictor is constituted by a tremendously degenerated system, when only one agent is involved. The...

Many inspections are manipulable
Shmaya, Eran - In: Theoretical economics : TE ; an open access journal in … 3 (2008) 3, pp. 367-382
A self-proclaimed expert uses past observations of a stochastic process to make probabilistic predictions about the process. An inspector applies a test function to the infinite sequence of predictions provided by the expert and the observed realization of the process in order to check the...

Combining forecasts to enhance fish production prediction : the case of coastal fish production in Morocco
Bouras, David - In: Atlantic review of economics : AROE 2 (2015)
This paper seeks to enhance forecast accuracy by combining three individual forecasting models. These models include: the Autoregressive Integrated Moving Average model (ARIMA), the Generalized Autoregressive Conditional Heteroscedastic model (GARCH), and the Census X11 model. Applied to the...

Rationalizable conjectural equilibrium : a framework for robust predictions
Esponda, Ignacio - In: Theoretical economics : TE ; an open access journal in … 8 (2013) 2, pp. 467-501
I introduce a new framework to study environments with both structural and strategic uncertainty, different from Harsanyi's (1967-8) `Bayesian games', that allows a researcher to test the robustness of Nash predictions while maintaining certain desirable restrictions on players' beliefs. The...
