Developing a Model for Determining Corporate Performance after Bank Acquisition

This is a panel study designed to develop a model to determine bank performance after acquisition. Data Envelopment Analysis (DEA) using Value Added Approach which adopted both Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) models was employed to determine efficiency scores of the banks. The study examined 62 banks from 30 countries acquired in 2006 and which had data with Fitch/IBCA/Bureau Van Dijk Bankscope database. The banks were divided into large and small groups. The study period was from 2007-2012. Results from the VRS model were used for further analyses. The Malmquist TFP was determined to identify key value drivers in the acquired banks. Five environmental variables namely Corruption Perception Index (CPI), Bank Industry Concentration (BIC), Total Assets, Gross Domestic Product (GDP) and Real Interest Rates were regressed on the efficiency scores using fractional regression models to determine their impact on efficiency scores. The “Spearman rho” correlation between efficiency scores and profitability ratios was established
