Rapid quantification of myocardial fibrosis: a new macro-based automated analysis

Background: Fibrosis is associated with various cardiac pathologies and dysfunction. Current quantification methods are time-consuming and laborious. We describe a semi-automated quantification technique for myocardial fibrosis and validated this using traditional methods

Bank performance and executive pay: tournament or teamwork

We investigate the relationship between the dispersion of executive pay and bank performance/valuation by examining two competing theories, the tournament theory (hierarchical wage structure) and the equity fairness theory (compressed wage structure). The key variable of executive pay dispersion is measured using a hand-collected dataset composed of 63 banks from OECD countries and 29 banks from developing countries. The dataset covers the period 2004 to 2012. By combining and modifying a translog profit function and a pay-dispersion model, we are able to address the potential problems of relying on reduced-form estimation. In our subsample of developed and civil law countries, where bank performance is measured by either Tobin’s Q or by the price-to-book ratio, the overall impact of executive pay dispersion is mostly negative, and we find supporting evidence for the equity fairness theory, except for very high levels of dispersion. There is a non-linear effect, as banks perform best when there is either very low or very high executive pay dispersion. For developing country sample banks, greater executive pay dispersion has a negative impact on bank profit. In our subsample of common law countries, however, we find no evidence of a significant impact of executive pay dispersion on bank performance. We conclude that lower executive pay dispersion, a proxy for teamwork, is mostly effective in enhancing bank performance in a significant section of sample banks, i.e., civil law and developing countries

The search for value: cross-border bank M&A in emerging markets

Between 1998 and 2005, we identify 74 cross-border M&A transactions in which international banks acquired ownership stakes in 46 listed banks in emerging market economies (EME). A total of $1,057,515 million of bank assets was acquired for$38,172 million in Latin America, Central and Eastern Europe, and Asia. Using an event study approach, there is scant evidence of win-win situations when joint abnormal return is positive. Whereas abnormal returns to targets are mostly positive and significant, they tend to be offset by negative returns to acquiring banks, which drives joint returns. Econometric results find no evidence that acquisition of majority control leads to higher abnormal returns to target banks; rather, the opposite holds in banking which is inconsistent with evidence from the non-financial sector. Our evidence implies there are considerable perceived risks associated with expanding banking operations into emerging markets, which affects stockmarket valuation of cross-border M&A. Thus, the evidence does not support suggestions of a transfer of wealth from shareholders in emerging markets to their counterparts in industrialised markets
