The relationship between revenue diversification and bank performance
A B S T R A C T
This paper contributes to the existing literature by investigating the impact of revenue diversification on bank performance through a broad array of financial reforms, including credit controls, interest rate controls, entry barriers, banking supervision, privatization, and financial account restrictions. This analysis is the first to investigate whether financial structures (bank- or market-based systems) change the effect of diversification on individual bank performance. We use a panel dataset sample from 29 Asia- Pacific countries covering the period between 1995 and 2009, for a total of 2372 banks. Unlike the results of previous studies based on data from the U.S. and Europe, this study confirms the hypothesis of the portfolio diversification effect for the Asia-Pacific banking industry. For bank-based groups, bank performance can be improved through diversification, supporting the ‘‘bank-based view’’ hypothesis.
Corporate governance and investment-cash flow sensitivity: Evidence from emerging markets
Abstract
Controlling for country-level governance, we investigate how firms' corporate governance influences financing constraints. Using firm-level corporate governance rankings across 14 emerging markets, we find that better corporate governance lowers the dependence of emerging market firms on internally generated cash flows, and reduces financing constraints that would otherwise distort efficient allocation of investment and destroy firm value. Additionally and more importantly, firm-level corporate governancematters more significantly in countries with weaker country-level governance. This suggests substitutability between firm-specific and country-level governance in determining a firm's investment sensitivity to internal cash flows.
Herding behaviour and sentiment: Evidence in a small European market
Abstract
This work studies herding behaviour in a small European market, by analysing the stocks that constitutedthe Portuguese stock PSI-20 index, for the period between 2003 and 2011. The two different approachesused to measure herding intensity led to different results, suggesting that measurements of the herdingphenomenon are sensitive to the method used. Consequently, there is a need for further research into themethodology used to test this phenomenon. Additionally, the study analyses the relationship betweenherd behaviour and investor sentiment, an area that has been little explored. In applying causality teststo the impact of sentiment on herd behaviour, only weak evidence is found that sentiment influencesherding.
Governance, product market competition and cash management in IPO firms
Abstract
This study evaluates the link between CEO governance heterogeneity, power structure of the firm, and product market competition on various facets of post-IPO cash policy. Our results suggest that post-IPO cash holdings as well as marginal value of cash reserves are higher under a founder CEO governance regime relative to non-founder CEOs. Concentrating board power in the hands of founder CEOs however, reduces their ability to maintain higher post-IPO cash reserves. Our results also suggest that product market competition influences both the level and marginal value of cash reserves in the hands of founder CEOs. Further, we find that stronger internal governance reduces the tendency of IPO firms to deploy excess cash reserves to fund internal investments in excess of industry rivals. Finally, our results suggest that excess cash reserves in competitive industry environments lead to superior post-IPO operating performance.
The relationship of operational innovation and financial performance—A critical perspective
Abstract
Operations management designs, schedules, and controls organizational processes to increase productivity by using methods such as Just-in-Time (JIT)/Lean Manufacturing, Total Quality Management (TQM) or Environmental Management Systems (EMS). Following implementation, managers generally want to determine the impact of such operational innovations on firm performance. Past studies analyzed financial ratios to prove the usefulness of the operational methods; however, findings are mixed. While some reported positive relationships between operational innovations and financial performance, others found no or inconsistent relationships. Motivated to uncover explanations for said inconsistencies, this paper takes a critical look at the appropriateness of the profitability ratios Return on Asset (ROA), Return on Equity (ROE) and Basic Earning Power (BEP) in determining the impact of a given operations strategy on firm performance. Focusing on JIT/Lean Manufacturing, the relationship between these ratios and inventory management ratios is analyzed. Fixed-effect regression shows that no consistent relationship between ROA, ROE, BEP and inventory management ratios exists. This result may be explained, as the profitability of a firm is affected by at least two factors: results from its operations, and how these are financed (e.g. usage of cheap debt, which enhances profitability). This paper suggests that the impact of an individual operations strategy is difficult to isolate from other firm activities, such as its financial management. Hence, profitability ratios such as ROA, ROE and BEP that aggregate all of a firm's activities may not be suitable metrics to determine the effect of JIT/Lean Manufacturing methods on financial firm performance.
The short of it: Investor sentiment and anomalies
Abstract
This study explores the role of investor sentiment in a broad set of anomalies in cross-sectional stock returns. We consider a setting in which the presence of market-wide sentiment is combined with the argument that overpricing should be more prevalent than underpricing, due to short-sale impediments. Long-short strategies that exploit the anomalies exhibit profits consistent with this setting. First, each anomaly is stronger (its long-short strategy is more profitable) following high levels of sentiment. Second, the short leg of each strategy is more profitable following high sentiment. Finally, sentiment exhibits no relation to returns on the long legs of the strategies.
