On the Comparison of Akaike Information Criterion and Consistent Akaike Information Criterion in Selection of an Asymmetric Price Relationship: Bootstrap Simulation Results

Abstract

Akaike’s Information Criteria provide a basis for choosing between competing approaches to testing for price asymmetry. However, very little research has been undertaken to understand its performance in the price transmission modelling context. In addressing this issue, this paper introduces and applies parametric bootstrap techniques to evaluate the ability of Akaike Information Criteria (AIC) and Consistent Akaike Information Criteria (CAIC) in distinguishing between competing asymmetric price transmission models under various error and sample size conditions. Bootstrap simulation results suggest that the performance of the model selection methods depends on sample size and stochastic variance. The Bootstrap simulations further indicate that CAIC is consistent and performs better than the AIC in large bootstrap samples. The ability of the model selection methods to identify the true asymmetric price relationship decreases with increase in stochastic variance. The research findings demonstrate the usefulness of Bootstrap algorithms in price transmission model comparison and selection.
