Empirical studies investigate various causes and effects of sustainable investments. While some attempts have been made to describe the results found by theoretical models, these are relatively complex and idiosyncratic. We relate to existing studies and use a parsimonious CAPM in which we model...

Active fund managers implicitly promise to research profitable portfolio selection. But active management is an experience good subject to moral hazard. Investors cannot tell high from low quality up front and therefore fear manager shirking. We show how the parties mitigate the moral hazard by...
