Because target negativity has been empirically confounded with reduced stereotyping, the general effects of perspective-taking on stereotyping and prejudice are unclear.

A central decision faced by firms is whether to make intermediate components internally or to buy them from specialized producers. We argue that firms producing products for which rapid technological change is characteristic will benefit from outsourcing to avoid the risk of not recouping their sunk cost investments when new production technologies appear. This risk is exacerbated when firms produce for low volume internal use, and is mitigated for those firms which sell to larger markets.

Using panel data from a large hospital system, this paper presents estimates of the productivity effects of human capital in a team production environment. Proxying nurses' general human capital by education and their unit-specific human capital by experience on the nursing unit, we find that greater amounts of both types of human capital significantly improve patient outcomes.

This paper finds statistically and economically significant out-of-sample portfolio benefits for an investor who uses models of return predictability when forming optimal portfolios. The key is that investors must incorporate an ensemble of important features into their optimal portfolio problem, including time-varying volatility, and time-varying expected returns driven by improved predictors such as measures of yield that include share repurchase and issuance in addition to cash payouts. Moreover, investors need to account for estimation risk when forming optimal portfolios.
