We study a possible link between two recent U.S. labor market trends: incre
ased wrongful termination litigation and more frequent mass layoffs. We arg
ue that if workers are more likely to sue when fired than when dismissed as
part of a layoff then increases in the expected costs to firms of such sui
ts should induce substitution toward layoffs and away from individual firin
gs. Our empirical analysis supports this assertion, showing that shortly af
ter the passage of the Civil Rights Act of 1991, the methods of displacemen
t changed differently by race but changes to the overall level of displacem
ent were consistent across races.
