This paper provides a first step in developing a system-wide stress simulation. The model incorporates several important features of the financial system. These include several types of institution (including banks and non-banks) and how their actions may propagate and amplify stress. Rather...

We use the financial crisis of 2007-2009 as a laboratory to examine the costs and benefits of teams versus single managers in asset management. We find that when a fund uses complex trading strategies involving the use of CDS team-managed funds outperform solo-managed funds. This may be due to...

We evaluate popular measures of hedge fund tail risk such as maximum drawdown (MDD) and worst one-period loss, and prove theoretically that realized tail risk is a downward-biased estimator of true tail risk. The bias can be almost 100% using a reasonable calibration. That is, true tail risk can...

Lending to emerging market economies (EMEs) through bond purchases has surged since 2009. What are the risks of a sudden stop? Bond mutual funds may curtail credit through two channels. The first is redemptions by ultimate investors. The second is additional discretionary sales by fund managers,...

In this paper, I examine the flow and performance of mutual funds in Brazil and their portfolio allocations during the global financial crisis. First, I show that mutual funds exposed to deposits and securities issued by small banks suffered significant outflows, due to the increased risk...

The investment fund sector has expanded dramatically since the crisis of 2008-2009. As the sector grows, so do the implications of its risk-taking for the wider financial system and real economy. This paper provides empirical evidence for the existence of wide- spread risk-taking incentives in...

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...

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...

The aim of this paper is to present different views on Black-Scholes model. The Black-Scholes equation is one of the most significant equations in financial mathematics. It is commonly used to determine price of options. However its applications as well as modifications go far beyond this...
