In sequential interactions, both the agent’s intention and the outcome of his choice may influence the principal’s action.

We examine the 1999 pension reform in Germany, which increased the ERA for women born after 1951 by at least three years.

In 2014, disability benefits of new recipients were increased considerably while eligibility criteria were not changed. We exploit this quasi-experimental policy variation to test the implications at two different margins. First, we analyze to what extent an increase in the...
