|July 2020||Using Equity Market Reactions to Infer Exposure to Trade Liberalization|
with , , : w27510
We outline a method for using asset prices to identify firm exposure to changes in policy. We highlight the benefits of this approach for studying trade agreements and apply it to two US trade liberalizations, with China and Canada. We find that abnormal equity returns during key events associated with these liberalizations are correlated with standard measures of import competition, vary across firms even within industries, predict subsequent firm outcomes, and provide a more complete view of distributional implications. In both cases, predicted relative increases in operating profit among the largest firms dwarf the relative losses of smaller firms.
|April 2020||Aggregate and Firm-Level Stock Returns During Pandemics, in Real Time|
with , , : w26950
We show that unexpected changes in the trajectory of COVID-19 infections predict US stock returns, in real time. Parameter estimates indicate that an unanticipated doubling (halving) of projected infections forecasts next-day decreases (increases) in aggregate US market value of 4 to 11 percent, indicating that equity markets may begin to rebound even as infections continue to rise, if the trajectory of the disease becomes less severe than initially anticipated. Using the same variation in unanticipated projected cases, we find that COVID-19-related losses in market value at the firm level rise with capital intensity and leverage, and are deeper in industries more conducive to disease transmission. These relationships provide important insight into current record job losses. Measuring US s...
