This paper shines light on subsidy-dependent microfinance institutions (MFIs). Firstly, our model shows that subsidy uncertainty can have pervasive effects on MFIs’ poverty-reduction mission. In particular, we argue that supply-driven uncertainty can lead to mission drift. MFIs maximize...

The market portfolio efficiency remains controversial. This paper develops a new test of portfolio mean-variance efficiency relying on the realistic assumption that all assets are risky. The test is based on the vertical distance of a portfolio from the efficient frontier. Monte Carlo...

Addressing crises raises a sharp reference-class problem in economics. Namely, economic theory lacks an inclusive and consistent classification of crises. This problem stems from the fact that economists tend to adapt their views on crises to recent episodes, and omit averted and potential...

Exploiting cross-sectional and time-series variations in European regulations during the July 2008 – June 2009 period, we show that: 1) Prohibition on covered short selling raises bid-ask spread and reduces trading volume, 2) Prohibition on naked short selling raises both volatility and...

Art is often used as an investment vehicle. Given the importance of market efficiency in finance, we use a large auction-based index to test whether the art market is weakly efficient. Evidence reveals that returns on artworks exhibit high positive auto-correlation. We attribute this result to...

This paper starts from the observation that 23% of the world’s microfinance institutions (MFIs) manage without subsidies. We examine how unsubsidized institutions cope with their social mission. Overall, the lack of subsidies worsens social performances. However, our results show that...

Women entrepreneurs are known not only to reimburse loans swifter than men, but also to receive smaller loans. However, on average women have smaller-scope business projects and are poorer than men. A deeper investigation is thus required in order to assess the existence of gender discrimination...

Bernoulli’s (1713) well-known Law of Large Numbers (LLN) establishes a legitimate one-way transition from mathematical probability to observed frequency. However, Bernoulli went one step further and abusively introduced the inverse proposition. Based on a careful analysis of Bernoulli’s...

How do women leaders such as board members and top managers influence the social performance of organizations? This paper addresses the issue by exploiting a unique database released by a Senegalese network of 36 financial cooperatives sharing identical governance characteristics and placed...

This paper is the first to draw a global picture of worldwide microfinance equity by taking full advantage of daily quoted prices. We revisit previous findings showing that investors should consider microfinance as a self-standing sector. Our results are threefold. First, microfinance has become...
