How to quantify the informational content of analyst reports? In this short methodological paper, we propose a measure of information contribution (IC), defined in the spirit of Shapley values. We use natural language processing to identify topics for over 90,000 analyst reports for S&P 500...

Supranational resolution of insolvent banks does not necessarily improve welfare. Supranational regulators are more inclined to bail-out banks indebted towards international creditors because they take into account cross-border contagion. When banks' creditors are more likely to be bailed out,...

We provide evidence of the effects of introducing a central clearing counterparty (CCP) on price stability by adopting as an experimental construct the 2009 clearing reform in three Nordic equity markets. We find that the daily price volatility of the affected equities experience an economically...

Speeding up the exchange does not necessarily improve liquidity. On the one hand, more speed enables a high-frequency market maker (HFM) to update his quotes faster on incoming news. This reduces his payoff risk and thus lowers the competitive bid-ask spread. On the other hand, HFM price quotes...

I build a model of delegated asset management with moral hazard and security lending. Lending markets transfer informational rents from short-sellers to funds. Investors optimally receive the proceeds as state-contingent dividends which correlate with shorting demand, providing a natural hedge....

Liquidity providers (LPs) on decentralized exchanges pay a fixed transaction cost (gas price) whenever they update their positions. Different economies of scale across LPs lead in equilibrium to the fragmentation of liquidity supply between low- and high-fee pools. Using data on liquidity...

We document low cross-sectional correlations between high-frequency market maker (MM) inventory positions, suggesting poor risk sharing. Using a unique data set on Canadian futures markets, a simple inventory cost estimate is 300% above the optimal benchmark. Our model explains how heterogeneity...
