We demonstrate that advisory fees exhibit a positive concave dependence on the idiosyncratic volatilities of mutual fund returns. Our theoretical analysis attributes this to the impact of idiosyncratic noise on performance opacity, coupled with the infeasibility of short-selling mutual fund...

In an Ito-diffusion market, two fund managers trade under relative performance concerns. For both the asset specialization and diversi?cation settings, we analyze the passive and competitive cases. We measure the performance of the managers' strategies via forward relative performance criteria,...

The paper proposes a model of delegated portfolio management in which career concerns lead to unprofitable trade by uninformed managers (i.e. churning). We find that churning does not necessarily reduce the return that a representative investor expects ex-ante from delegating trade to a manager....

We study product differentiation in the mutual fund industry. We design a model in which funds with heterogeneous perceived quality can choose their level of product differentiation. In equilibrium, high quality funds choose broad market designs (i.e., low differentiation) appealing to many...

We propose and test a framework of private information acquisition and decision timing for asset allocators hiring outside investment managers. Using unique data on due diligence interactions between an allocator and 860 hedge funds, we find that the production of private information complements...

I present a dynamic investment model in which mutual funds' inferior performance is an equilibrium response to incentives rather than the consequence of low skills. In the model, a skilled (informed) manager responds to investors' flows, which are a convex function of performance relative to...

In this paper, I analyse the reciprocal social influence on investment decisions within an international group of roughly 2000 mutual fund managers that invested in companies of the DAX30. Using a robust estimation procedure, I provide empirical evidence that in the average a fund manager puts...

Analyzing a large sample of gross fund-level and deal-level returns in Private Equity (PE), we study systematic differences in investment skills across PE firms and what investors can learn about the true skill of PE firms from past performance. We extend the framework of Korteweg and Sorensen...

The recent mania of Reddit darling GameStop raises questions about social media’s impact on the behaviours of institutional investors such as mutual funds. We examine whether and why mutual funds hold “sentimental” stocks that are heavily mentioned or with bullish views on social media....

This paper measures the extent of uncertainty in mutual fund communication and its effects on fund flows. I test the hypothesis that mutual funds communicating more about uncertainty might avoid large outflows. Investors appear to react to this form of communication, as the use of uncertain...
