We apply an double bootstrap approach introduced by Simar and Wilson (2007) to examine bank/organization efficiency. In the first stage, we adopt DEA to estimate the relative efficiency scores in the sample using, alternatively, constant returns to scale and variable returns to scale. In the second stage, we apply the Simar and Wilson (2007) procedure to bootstrap the DEA scores with a truncated bootstrapped regression. An integral part of the analysis is to explore the determinants of bank/organization efficiency.

An applicant for admission to read for a PhD should normally hold a first or upper second class honours degree of a UK university or an equivalent qualification, or a lower second class honours degree with a Master's degree at Merit level of a UK university or an equivalent qualification.
International students will also need to meet the English language requirements - IELTS 6.5 (with minimum sub-scores of 6.0). Applicants who have taken a higher degree at a UK university are normally exempt from the English language requirements. A research proposal (between 1,000 and a maximum of 2,000 words) must be submitted as part of the application.
