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...

Several years after the reform of the pension scheme in Nigeria, there is still trepidation about the success of the scheme. A particularly knotty issue is the mode of collecting benefits after retirement. It would seem that many retirees prefer programmed withdrawal to annuities without...

Since the National Health Insurance Scheme (NHIS) was established in Nigeria, in 1999, not much study has been carried out to investigate whether access to quality health care has improved as a result of the introduction of the scheme. Using primary data from Lagos, this study applies logistic...

Traditional sampling techniques have not yielded desired results when applied to hidden or rare populations. A hidden population of considerable interest in Nigeria is that of students in tertiary institutions engaged in substance abuse because of the stigma surrounding such habits and the high...

The paper introduces a new dynamic frontier model that is used to analyze the impact of both ownership and regulation on airport technical and allocative efficiencies. We differentiate between the short and long-term effects. Based on a large sample of international airports, we find in the...

This paper examines the performance of European banks during the pre-crisis and post-crisis periods, both in terms of technical and allocative efficiencies. We use an innovative Bayesian dynamic frontier model that: (1) distinguishes between short-run and long-run performance; and (2) provides...

Set in the airport industry, this paper measures firm performance using both desirable and bad outputs (i.e. airport delays). We first estimate a model that does not include the bad outputs and then a model that includes bad outputs. The results show important differences in the efficiency and...
