Baquero G, Hamadi Malika, Heinen A (2018) Competition, Loan Rates and Information Dispersion in
Nonprofit and For-profit Microcredit Markets,
Journal of Money, Credit, and Banking 50 (5) pp. 893-937 Wiley
We describe the competitive environment of microcredit markets globally and we study
the effects of competition on loan rates of microfinance institutions (MFIs). We use
a new database from rating agencies, covering 379 for-profit and nonprofit MFIs in
67 countries over 2002-2008. Controlling for interest rate ceilings and other countryspecific
factors, we first find that nonprofits are relatively insensitive to industry-wide
concentration changes, while for-profits charge significantly lower rates in less concentrated
markets. Second, we find spillover effects between the for-profit and nonprofit segments. Third, we show that the effects of concentration are consistent with an
information dispersion mechanism.
Hamadi M, Heinen A, Linder S, Porumb V (2016) Does Basel II affect the market valuation of discretionary loan loss provisions?, Journal of Banking & Finance 70 pp. 177-192 Elsevier
We use a sample of banks from 24 European countries to investigate whether the adoption of the Basel II Capital Accord in 2008 affects the market valuation of discretionary loan loss provisions (DLLPs). Although Basel II lowers the incentives of internal ratings-based (IRB) banks to recognize income-increasing DLLPs in an opportunistic manner, it has no such impact on the remaining banks, which adopt the Standardized methodology. We use this setup in a difference-in-difference (DiD) design, where Standardized banks act as a control group. Our evidence supports the three hypotheses that, for IRB relative to Standardized banks, Basel II is associated with (i) less income-increasing DLLPs and (ii) less income-smoothing via DLLPs, which enhances the informational content of DLLPs about future loan losses and leads to (iii) higher market valuation of DLLPs. Our findings are timely and have policy implications for future regulatory developments in the banking industry.
Anderson R, Hamadi M (2016) Cash holding and control-oriented finance, Journal of Corporate Finance 41 pp. 410-425 Elsevier
We critically reassess the notion that high liquid asset holding by firms faced with weak investor protection is evidence of managerial rent extraction. We show that firms facing agency problems may establish tight controls over management through concentrated ownership. Using data on Belgian listed firms between 1991 and 2006, we find a strong positive association between ownership concentration and cash holding. This indicates a precautionary motive on the part of the controlling shareholders who highly value control. We also find that firm market valuation is positively affected by the amount of cash held by firms. On the other hand, managerial ownership has no impact. These results are consistent with the hypothesis that firms' owners are pursuing a rational strategy to mitigate agency costs in the face of weak investor protections.
Hamadi M, Heinen A (2015) Firm performance when ownership is very concentrated: Evidence from a semiparametric panel, Journal of Empirical Finance 34 pp. 172-194 Elsevier
We consider the effect on performance of very large controlling shareholders, who are mostly organized in voting blocks and business groups, in a sample of Belgian listed firms from 1991 to 2006. Since the shape of the relation between ownership and firm value is a controversial issue in corporate finance, we use semiparametric local-linear kernel-based panel models. These models allow us not to impose a priori functional restrictions on the relation between ownership and performance. Our semiparametric analysis shows that the effect on performance varies depending on the size of ownership stakes and that there are departures from linearity, especially in family firms. Our results suggest that this non-linearity in family firms is related to whether or not the CEO is a family member.
