This paper explores the extent to which correlated investments in the futures market concentrated systemic risk on large Canadian banks around the 2008 crisis. We find that core banks took positions against the periphery, increasing their systemic risk as a group. On the portfolio level,...

The classic Arrow-Debreu framework requires a very large number of specific securities to reach Pareto optimality. The present paper shows that financial intermediation can play an important role in maintaining a more parsimonious market framework while still obtaining Pareto optimality. In the...

The past couple of decades have seen a significant shift from active to passive investment strategies. We examine how this shift affects financial stability through its impacts on: (i) funds' liquidity and redemption risks, (ii) asset-market volatility, (iii) asset-management industry...

We examine the determinants and consequences of mutual fund managers simultaneously managing multiple funds. Well-performing managers multitask by taking over poorly performing funds or launching new funds. Subsequent to multitasking, funds run by managers prior to multitasking (i.e., incumbent...

We examine the determinants and consequences of the multitasking phenomenon in the mutual fund industry where fund managers simultaneously manage multiple funds. We show that wellperforming managers multitask either by taking over poorly performing funds within fund companies (i.e., acquired...

We examine portfolio trading and its impact on corporate bond liquidity. Our theoretical framework identifies how portfolio trades provide dealers with benefits through a diversification channel and with costs through a balance sheet channel. We then test empirically multiple hypotheses on the...

General Partners (GPs) in private equity face a trade-off between focusing their skills and effort on fewer investments to earn higher returns, or investing more broadly to reduce risk through diversification. Using a novel, deal-level dataset of 5,925 global investments from 1999 to 2016, we...

We consider the finite-time optimal portfolio liquidation problem for a von Neumann-Morgenstern investor with constant absolute risk aversion (CARA). As underlying market impact model, we use the continuous-time liquidity model of Almgren and Chriss (2000). We show that the expected utility of...

We explore the link between mutual funds and fragility risk in the corporate bond market. We classify a fund's trading style based on its responses to signals of large dealer inventories. Trading style is persistent and the majority of funds demand liquidity. Notably, a subset of funds earn...
