This study examines long-term excess returns subsequent to directors' dealings announcements between January 2002 and December 2009 from 17 Western European countries. Excess returns are adjusted with equally weighted portfolios which are size and sector neutral. The main findings show that...

A key problem facing microlenders is the high level of information asymmetry between them and their borrowers. In this paper, we analyze whether the relationship intensity between microlenders and borrowers helps to overcome existing information asymmetries and how this impacts access to credit...

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...

We use a natural experiment and matched bank/firm data to identify the effects of bank guarantees on allocative efficiency. We find that with guarantees in place unproductive firms invest more and maintain higher rates of sales growth. Moreover, firms produce less productively. Firms also...

In this paper we propose a quasi-shrinkage approach for minimum-variance portfolios which does not use a quadratic loss function to derive the optimal shrinkage intensity. We develop two alternative objective functions for linear shrinkage. The first targets the reduction of portfolio variance....
