We evaluate the impact of the 2008 Apex Oil court decision that made the creditors of some corporations financially liable for the environmental damages caused by specific pollutants. Apex reduced the circumstances under which environmental liabilities were dischargeable in Chapter 11, which...

We show that financial constraints may benefit innovation by improving the efficiency of innovative activities. We measure firm-level innovative efficiency by patents (or patent citations) scaled by R&D (research and development) investment or the number of employees, and find that financial...
