Have banks become more similar? In this paper we test this hypothesis using data on Japanese banks' loan portfolios over the period 1996–2013. Using various similarity measures, we find that banks have in fact become less similar over time. This finding would suggest that concerns over a more...

Mutual fund risk-taking via active portfolio rebalancing varies both in the crosssection 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...

Financial networks are an important source of systemic risk, but often only partial network information is available. In this paper, we use data on bank-firm credit relationships in Japan and conduct a horse race between different network reconstruction methods in terms of their ability to...

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...

In this paper, we consider models of price-mediated contagion in a banking network of common asset holdings. For these models, the literature proposed two alternative classes of liquidation dynamics: threshold dynamics (banks liquidate their investment portfolios only after they have defaulted),...
