Tarasoff, duty to warn laws, and suicide

► I estimate the effect of state duty to warn (DTW) laws on teen and adult suicides. ► Identification for panel estimation comes from variation in timing and style of DTW laws. ► Teen suicides, which should be directly affected by DTW laws, increase in the presence of DTW laws. ► Adult suicides, which would only be indirectly affected by DTW laws, experience no change.
