This paper investigates the use of Bayesian mixed logit models to simulate competitive dynamics in product design, focusing on the ability of these models to accurately predict Nash equilibria. It addresses a gap in the literature by incorporating fully Bayesian choice models and assessing their performance under different choice behaviors. The research is significant because it provides insights into the reliability of these models for strategic decision-making in product development and pricing.
Key Takeaways
- •The accuracy of Nash equilibrium prediction using mixed logit models depends on the type of choice behavior (probabilistic vs. deterministic).
- •Deterministic choice rules applied to estimated preferences given deterministic choice behavior yield the highest equilibrium recovery.
- •Incorporating Bayesian (hyper)parameter uncertainty enhances detection rates, especially in deterministic choice settings.
- •The study also investigates the influence of factors like preference heterogeneity on product differentiation.
