Against the backdrop of COVID-19, we study how the interactions of mutual funds and dealers introduce fragility to the municipal bond market and carry lasting impacts. During the crisis, trading activities surge while dealers' liquidity provision plunges for mutual-fund-held bonds, leading to...

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...

The level of diseconomies of scale in asset management has important implications for tests of manager skill and the expected level of performance persistence. To identify the causal impact of fund size on future returns, we exploit the fact that small differences in returns can cause discrete...

Theoretical models imply fund size and performance should be negatively linked. However, empiricists have failed to uncover consistent support for this negative relation. Using a new econometric framework which includes fund-specific sensitivities to decreasing returns to scale, we find a both...

Final working paper version. "" Published version: The Review of Financial Studies, Volume 31, Issue 7, July 2018, pp. 2499–2552. Past fund performance does a poor job of predicting future outcomes. The reason is noise. Using a random effects framework, we reduce the noise by pooling...

Using the universe of Business Development Companies (BDCs), a unique publicly traded segment of U.S. Private Equity (PE), for the period 1998-2017 we provide the first in depth examination of their performance and risk adjusted characteristics. More importantly, we show that the readily...

Quantitative research analysts (Quants) produce in-depth quantitative and econometric modeling of market anomalies to assist sell-side analysts and institutional clients with stock selection strategies. Quants are associated with more efficient analyst forecasting behavior on anomaly predictors...

Using a novel database, we show that the stock-price impact of analyst trade ideas is at least as large as the impact of stock recommendation, target price, and earnings forecast changes, and that investors following trade ideas can earn significant abnormal returns. Trade ideas triggered by...

Using a novel return-based method to detect allocations of corporate bond offerings, which are underpriced on average, we find that mutual funds most active in the primary market generate significant alpha and outperform those that are less active. Our evidence suggests that underwriters direct...
