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. In this paper, we propose a parametric portfolio policy that uses industry return momentum to improve portfolio performance. Our portfolio policies outperform a broad selection of established portfolio strategies in terms of Sharpe ratio and certainty equivalent returns. The proposed policies are particularly suitable for investors because portfolio turnover is only moderately increased compared to standard minimum-variance portfolios.

Abstract We investigate whether firms’ number of credit relationships with financial institutions affects labor market outcomes. Using 5 million observations on matched credit and labor panel data from Brazil, we estimate IV regressions, employing exogenous variation in firm-lender relationships due to nationwide bank M&A activity. Firms with more relationships employ more workers and pay higher wage bills. Credit availability, cost of credit, and financial institution heterogeneity are economic channels. The firm-level results translate into positive macroeconomic effects in municipalities and states. The evidence is novel and indicates the positive effects of multiple relationships on labor market outcomes in an emerging economy.

We investigate the implications of providing loan officers with a nonlinear compensation structure that rewards loan volume and penalizes poor performance. Using a unique data set provided by a large international commercial bank, we examine the main activities that loan officers perform: loan prospecting, screening, and monitoring. We find that when loan officers are at risk of losing their bonuses, they increase prospecting and monitoring. We further show that loan officers adjust their behavior more toward the end of the month when bonus payments are approaching. These effects are more pronounced for loan officers with longer tenures at the bank.
