- Analysis of price transmission and asymmetric adjustments using Bayesian methods (PhD Thesis)
Within the econometric models of asymmetric price transmission, different specifications which detect asymmetry at different rates have been developed. This leads to issues of model comparison and model selection, measuring the relative merits of alternative specifications and using the appropriate criteria to choose the most reliable method or model specification which best fits or explains a given set of data. The Bayesian theory which provides a flexible and conceptually simple framework for comparing competing models is introduced and developed for the price transmission models. On the basis of Marginal likelihood and Information Criteria, alternative methods of testing for asymmetry are evaluated when the true asymmetric data generating process is known. Using a Monte Carlo simulation of model selection, the performance of a range of Bayesian algorithms to clearly identify the true asymmetric data generating process is examined and the effects of the amount of noise in the model and the sample size on model selection are also simulated.
