This study analyses the cost-efficiency of Nigerian banks pre and post the consolidation period. The researchers account for bank heterogeneity using the Bayesian random frontier model, which in this context provides a better fit than the traditional stochastic frontier model. From the...

This paper analyzes the impact of vertical integration, age, geographic expansion, and low price strategy on the cost efficiency of retail stores. We test our hypotheses using the innovative Bayesian frontier methodology. The data involve a sample of Spanish retail stores that operate in a...

This paper analyzes the cost efficiency of UK airports over the period 1998–2008, using a Bayesian dynamic frontier model. This model provides a more structural explanation for the variation in airports inefficiency than has been presented by previous models, and also allows for cost...
