Recipients of fraudulent Paycheck Protection Program (PPP) funds significantly increased their home purchasing rate compared to recipients of non-fraudulent PPP funds, and house prices in high-fraud ZIP codes increased 5.8 percentage points more than in low-fraud ZIP codes within the same county.…

Trading with intermediaries before observing the shock commits sellers not to keep high-quality assets in such states, improving surplus despite impeding efficient use of information.

We provide novel evidence suggestive of insider trading through concealed relationships identified using information from over 100,000 Facebook profiles and their 35 million friends. Focusing on connections between fund managers and firm officers, we demonstrate that hidden ties are linked to substantial abnormal returns averaging 135 basis points per month (exceeding 16% alpha annually, t -stat …

Index funds’ long-short rebalancing portfolios have an annualized return of 4.61% and load negatively on value and profitability factors.
