Income diversification and bank performance: evidence from BRICS nations

PurposeThe purpose of this paper is to examine the impact of income diversification on bank performance in BRICS countries as a structural response to concentration risk. The authors argue that effectiveness of this approach is conditional upon its extent and quality. To understand the role of firm-specific characteristics on effectiveness of diversification, the authors examine this relationship across asset sizes.Design/methodology/approachAn unbalanced panel data set of 169 BRICS banks is sampled over the period 2001–2015. Fixed effect models and system generalized method of moments techniques are used to test the relationship between diversification and bank performance using alternate measures.FindingsResults indicate a positive relationship between diversification and performance measured in terms of bank risk and returns for medium and large size banks. However, for small banks this relationship is negative suggesting a “diversification discount.”Originality/valueThe study indicates that diversification as a risk mitigating tool can be effective but the managers and regulators should not emphasize on the “one-size-fits-all” approach for all banks. Policy frameworks for controlling concentration risk should be developed keeping in mind factors like bank size, customer base and financial leverage which brings variations to the risk profile of banks.

Can informal corporate governance mechanisms mitigate diversification discount? Evidence from Malaysia

Purpose The purpose of this paper is to examine whether any specific informal corporate governance mechanisms under consideration in this study, namely, political connection, business group affiliation and ownership concentration, are able to mitigate the diversification discount for emerging-market diversified firms using Malaysia as an examination lab. Design/methodology/approach The study uses a sample data of the entire non-financial public-listed firms in Malaysia over a 12-year period from 2001 to 2012. The generalized method of moments estimators are employed to account for the endogeneity of both corporate governance and diversification. Findings This study finds that business group affiliation particularly with large size can help to mitigate the diversification discount whereby political connection and ownership concentration magnify the discount. The finding is robust to alternative diversification measurements, to alternative methods and to endogeneity bias. Research limitations/implications This result implies that diversified firms with affiliation to large business groups are able to reduce the magnitude of the discounted value of diversification. Practical implications This study helps managers, shareholders and investors to evaluate their current/future investments related to firms with diversified business segments. This study also provides implications for policymakers and regulatory bodies to assess the adequacy and competency of the current corporate governance frameworks in place. Originality/value This study incorporates the country-specific institutional dimension in designing a research framework that is more relevant in examining the influential effect of governance-related characteristics on the diversification-firm value relationship in an emerging market.

Corporate diversification

Purpose The purpose of this study is to compare two theories that relate the proportion of diversified firms in the economy and the implied discount for diversified firms: the first is a real-options model predicting a positive relationship between the discount and management’s choice to operate a diversified firm; the second is based on catering theory, in which a negative relationship is predicted, as management is attentive to investor preference concerning diversified firms. Design/methodology/approach This study proposes a new aggregate measure of the diversification discount. The authors’ measure allows for decomposition of the discount into firm-level mispricing, industry-level mispricing and long-run fundamental value components. Findings Results support a catering theory of diversification. The discount appears to be the result of firm-level mispricing. Thus, providing an explanation for why, in light of the observed discount, a large number of diversified firms persist. Originality/value To the authors’ knowledge, this is the first study to provide evidence that firm-level mispricing may drive the observed diversification discount.

Technological Specialization and the Decline of Diversified Firms

We document a strong decline in corporate-diversification activity since the late 1970s, and we develop a dynamic model that explains this pattern, both qualitatively and quantitatively. The key feature of the model is that synergies endogenously decline with technological specialization, leading to fewer diversified firms in equilibrium. The model further predicts that segments inside a conglomerate should become more related over time, which is consistent with the data. Finally, the calibrated model also matches other empirical magnitudes well: output growth rate, market-to-book ratios, diversification discount, frequency and returns of diversifying mergers, and frequency of refocusing activity.
