We reassess the recent finding that no established portfolio strategy outperforms the naively diversified portfolio, 1/N, by developing a constrained minimum-variance portfolio strategy on a shrinkage theory based framework. Our results show that our constrained minimum-variance portfolio yields...

Minimum-variance portfolios, which ignore the mean and focus on the (co)variances of asset returns, outperform mean–variance approaches in out-of-sample tests. Despite these promising results, minimum-variance policies fail to deliver a superior performance compared with the simple 1/N rule....

Using a unique data set for a commercial bank in Albania, we analyze gender differences in loan officers' performance. Loans screened and monitored by female loan officers have a lower likelihood to turn problematic than loans handled by male loan officers. This effect cannot be explained by...

We model an economy where it is beneficial for high-type organizations to collaborate with other high types, and where this assortative-matching pattern allows informed financiers to provide inexpensive funds to partner companies of their high-type ventures. The expected funding benefit...

Micro-entrepreneurs often lack the financial literacy required to make important financial decisions. We conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb...

Individuals and business owners engage in an increasingly complex array of financial decisions that are critical for their success and well-being. Yet a growing literature documents that in both developed and developing countries, a large fraction of the population is unprepared to make these...
