We investigate how firms react to their product-market peers’ commitment to and adoption of corporate social responsibility (CSR) using a regression discontinuity design approach. Relying on the passage or failure of CSR proposals by a narrow margin of votes during shareholder meetings, we find the passage of a close-call CSR proposal and its implementation are followed by the adoption of similar CSR practices by peer firms. In addition, peers that have greater difficulty in catching up with the voting firm in CSR experience significantly lower stock returns around the passage, consistent with the notion that the spillover effect of the adoption of CSR is a strategic response to competitive threat. Using alternative definitions of peers and examining underlying mechanisms, we further rule out alternative explanations, such as that based on propagation by financial intermediaries.

This paper examines the effect of product market threats on firms’ stock crash risk. Competitive pressure from the product market aggravates managers’ incentive to withhold negative information. When negative information is accumulated to a tipping point, the accumulated information comes out all at once and leads to an abrupt and large decline in stock price. Using a measure of product market threats, our regressions find that firms facing more threats are more prone to stock crashes. This result is confirmed by an instrumental variable analysis and a difference-in-difference analysis with an exogenous shock to market competition. This paper was accepted by Neng Wang, finance.

Using brokerage mergers and closures as natural experiments, we examine how exogenous changes in the information environment affect a firm’s financing choice. Our difference-in-differences approach shows that exogenous increases in information asymmetry lead firms to substitute away from equity and public debt toward bank debt. Firms with higher risk tend to substitute equity for bank debt, and firms with lower risk tend to substitute bonds for bank debt. The effect of the change in the information environment on a firm’s financing choice is more pronounced for firms with worse information environments, such as those with few initial analysts and younger firms. We demonstrate that the mechanism of the change is through a reduction of the issuance of equity and bonds but with an increase of the issuance of bank loans. Further analysis reveals that such firms tend to reduce long-term borrowing, reduce their issuance of subordinated debt, and increase their revolving credit lines.

We uncover new return predictability in the cross-section of delta-hedged equity options. Expected returns to writing delta-hedged calls are negatively correlated with stock price, profit margin, and firm profitability, but positively correlated with cash holding, cash flow variance, new shares issuance, total external financing, distress risk, and dispersion of analysts’ forecasts. Our option portfolio strategies have annual Sharpe ratio above two and remain profitable after transaction costs. Their profits can be explained by two option factors, while equity risk factors have no explanatory power. We find support for several economic channels at work, yet the option return predictability remains puzzling.

Cyst fluid CEA level and cytology obtained by EUS-FNA are useful for predicting the malignancy of pancreatic MCN.

UGIB is a common complication with poor prognosis due mainly to PU and AGML. Patients having SAP with high APACHE II scores and CTSI or low PaO2 should be considered to be at high risk for UGIB.

Increased LDH, high CTSI, delayed fluid resuscitation and hypoxemia are independent risk factors for predicting pancreatic infection in patients with SAP.
