Improving Access to Banking: Evidence from Kenya

Review of Finance 2021 25(2), 403-447
We explore the relationship between bank branch expansion, financial inclusion, and profitability for Equity Bank. Unlike traditional banks, including foreign and government owned banks in Kenya, Equity Bank targets less developed territories and less privileged households. Its presence increased financial inclusion by 31% of the adult population between 2006 and 2015, especially for Kenyans who were less educated, did not own their own home, and lived in less-developed areas. The bank’s business model proves to be highly effective, with branch-level profits rising in areas with a smaller number of operating banks. Overall, the growth of Equity Bank demonstrates that financial inclusion can be achieved and sustained through profitable branching and service strategies that also serve the needs of underserved regions and populations. Thus, financial inclusion need not come at the sacrifice of bank profitability.

Beauty Contests and Iterated Expectations in Asset Markets

Review of Financial Studies 2006 19(3), 719-752
In a financial market where traders are risk averse and short lived and prices are noisy, asset prices today depend on the average expectation today of tomorrow’s price. Thus (iterating this relationship) the date 1 price equals the date 1 average expectation of the date 2 average expectation of the date 3 price. This will not, in general, equal the date 1 average expectation of the date 3 price. We show how this failure of the law of iterated expectations for average belief can help understand the role of higher-order beliefs in a fully rational asset pricing model.

A Theory of Dividends Based on Tax Clienteles

Journal of Finance 2000 55(6), 2499-2536
This paper explains why some firms prefer to pay dividends rather than repurchase shares. When institutional investors are relatively less taxed than individual investors, dividends induce “ownership clientele” effects. Firms paying dividends attract relatively more institutions, which have a relative advantage in detecting high firm quality and in ensuring firms are well managed. The theory is consistent with some documented regularities, specifically both the presence and stickiness of dividends, and offers novel empirical implications, e.g., a prediction that it is the tax difference between institutions and retail investors that determines dividend payments, not the absolute tax payments.

Financing firms in India

Journal of Financial Intermediation 2012 21(3), 409-445
With extensive cross-country datasets and India firm samples, as well as our own surveys of small and medium firms, we examine the legal and business environments, financing channels, and growth patterns of different types of firms in India. Despite the English common-law origin and a British-style judicial system, Indian firms face weak investor protection in practice and poor institutions characterized by corruption and inefficiency. Alternative finance, including financing from all nonbank, nonmarket sources, and generally backed by nonlegal mechanisms, constitutes the most important form of external finance. Bank loans provide the second most important external financing source. Firms with access to bank or market finance are not associated with higher growth rates. Our results indicate that bank and market finance is not superior to alternative finance in fast-growing economies such as India.

Financial crisis, structure and reform

Journal of Banking & Finance 2012 36(11), 2960-2973 open access
In this study, we examine the relationship between the structure of financial systems and financial crises. Using cross-country data on financial structures and crises, we find that there is a significant short-term reversal in development of the banking sector and the stock market during both bank crises and market crashes, with the corporate bond market moving in the same direction as bank credit. However, the results are significant for countries with market-based financial systems but not for countries with bank-based financial systems. Emerging markets have mainly bank-based financial systems, which may explain why these markets require more time to recover from economic downturns after a financial crisis. Therefore, we argue that governments should emphasize a balanced financial system structure as it helps countries to recover from financial crises more quickly compared with countries that lack such balanced structures.

Entrusted loans: A close look at China's shadow banking system

Journal of Financial Economics 2019 133(1), 18-41 open access
We perform transaction-level analyses of entrusted loans, one of the largest components of shadow banking in China. Entrusted loans involve firms with privileged access to cheap capital channeling funds to less privileged firms, and the increase when credit is tight. Nonaffiliated loans have much higher interest rates than both affiliated loans and official bank loans, and they largely flow into real estate. The pricing of entrusted loans, especially of nonaffiliated loans, incorporates fundamental and informational risks. Stock market reactions suggest that both affiliated and nonaffiliated loans are fairly compensated investments.

Bank lending, crises, and changing ownership structure in Central and Eastern European countries

Journal of Corporate Finance 2017 42, 494-515 open access
We examine the interactions of bank lending dynamics, ownership structures, and crisis phenomena in the banking systems of Central and Eastern European (CEE) countries. Using a panel dataset of more than 400 banks for the period from 1994–2010, we show that the impact of ownership structure on a bank’s lending activities in CEE countries was conditional upon the type of crisis, namely, whether it was a host, home, global, or simultaneous crisis. In contrast, our evidence indicates that bank-specific characteristics, such as deposit growth and profitability ratios, are significant determinants of credit growth during both normal economic times and crisis periods, regardless of the crisis type. Moreover, we provide indirect evidence of the benefits of banking sector diversification dependent upon the criterion of parent banks’ country of origin.

Monetary Policy and Rational Asset Price Bubbles: Comment

American Economic Review 2025 115(8), 2819-2847 open access
Galí (2014) showed that a monetary policy rule that raises rates when bubbles exceed some steady-state benchmark can paradoxically lead to larger deviations from steady state. Nevertheless, this comment shows that a central bank can always dampen a bubble by setting a higher-than-expected rate, although it may have to raise the rate aggressively. This is a different point from the Miao, Shen, and Wang (2019) comment on Galí (2014). They showed that when the central bank targets a different steady state than Galí considered, raising rates when bubbles exceed this alternative benchmark leads to smaller deviations from steady state.

Dissecting the Long‐Term Performance of the Chinese Stock Market

Journal of Finance 2024 79(2), 993-1054
Domestically listed Chinese (A‐share) firms have lower stock returns than externally listed Chinese, developed, and emerging country firms during 2000 to 2018. They also have lower net cash flows than matched unlisted Chinese firms. The underperformance of both stock and accounting returns is more pronounced for large A‐share firms, while small firms show no underperformance along either dimension. Investor sentiment explains low stock returns in the cross‐country and within‐A‐share samples. Institutional deficiencies in listing and delisting processes and weak corporate governance in terms of shareholder value creation are consistent with the underperformance in stock returns and net cash flows.
