    Bank opacity and risk-taking: Evidence from analysts’ forecasts
    (Elsevier, 2017-11-01) Fosu, Samuel; Ntim, Collins G.; Coffie, William; Murinde, V.
    We depart from existing literature by invoking analysts’ forecasts to measure banking system opacity and then investigate the impact of such opacity on bank risk-taking, using a large panel of US bank holding companies, over the 1995–2013 period. We uncover three new results. Firstly, we find that opacity increases insolvency risks among banks. Secondly, we establish that the relationship between opacity and bank risk-taking is accentuated by the degree of banking market competition. Thirdly, we show that the bank business model moderates the risk-taking incentives of opaque banks, albeit only marginally. Overall, these findings suggest that the analysts forecast measure of bank opacity is useful for understanding risk-taking by publicly-traded banks, with important implications for bank stability.

    Information Asymmetry, Leverage and Firm Value. Do crisis and growth matter?
    (Elsevier, 2016-05-10) Fosu, Samuel; Danso, Albert; Ahmed, Wasim; Coffie, William
    Drawing on pecking order and agency cost theories, we assess the extent to which information asymmetry is an important determinant of firm value and the extent to which this relationship is conditional on the leverage level of firms. We also assess the impact of information asymmetry on firm value during the pre and post 2007/09 financial crisis period and for high and low growth opportunity firms. Using a large sample of UK firms, our empirical findings suggest that information asymmetry adversely impacts firm value, and that this effect decreases with firm's leverage. We also find that leverage has a negative effect on firm value, and that the marginal effect of leverage is lower for information asymmetric firms. Further, we find that the relation between information asymmetry and firm value is more pronounced in the post-crisis period than the pre-crisis period. Finally, we show that the impact of information asymmetry on firm value is higher (lower) for firms with high (low) growth opportunities.

    Multifactor explanation of security returns in South Africa
    (International Journal of Management Practice, 2014) Fosu, Samuel; Coffie, William; Chukwulobelu, O.
    This paper evaluates the performance of the Fama and French threefactor model in South Africa for individual securities. We employed a multivariate time series methodology similar to Fama and French. The empirical results contradict the theoretical proposition of the Fama–French model and are inconsistent with the results documented by most studies in the developed and some emerging markets. The size and value premia are very weak when included in the regression model. Furthermore, the Fama and French three-factor model is unable to explain the return-generating process of securities trading on the Johannesburg Stock Exchange. This has important implication for corporate managers, investors as well as fund and portfolio managers in terms of estimating cost of equity, rate of return and portfolio allocation.
