Mutual fund risk-taking via active portfolio rebalancing varies both in the cross-section and over time. In this paper, I show that the same is true for funds' off- balance sheet risk-taking, even after controlling for on-balance sheet activities. For this purpose, I propose a novel measure of...

Using a sample of hedge funds and mutual funds, I examine two channels through which asset managers can contribute to systemic risk: the service channel when funds act as liquidity suppliers and the asset liquidation channel when funds act as liquidity demanders. Consistent with the latter...

Using microdata on stock-level lending positions from German mutual funds, we show that active funds use the equity lending market to obtain information about short sale demand. Funds reduce long positions in response to these demand signals, which allows fund managers to front-run public...

Is the asset management sector a source of financial instability? This paper develops a macroprudential stress test model which enables the quanti fication of systemic vulnerabilities due to fi re sales in this sector. The model incorporates the flow-performance relationship as an additional...

In this paper, I explore the relation between portfolio overlap and performance diversity. Using data on actively managed U.S. equity mutual funds, I find that the pairwise portfolio overlap between individual funds has increased over time and is significant compared to various randomized...

Is the asset management sector a source of financial instability? This paper contributes to the debate by performing a macroprudential stress test in order to quantify systemic risks in the mutual fund sector. For this purpose we include the welldocumented flow-performance relationship as an...

Investment funds are highly connected with each other, but also with the broader financial system. In this paper, we quantify potential vulnerabilities arising from funds' connectedness. While previous work exclusively focused on indirect connections (overlapping asset portfolios) between...
