A difference in difference framework
Reasons for being in the treatment group:
1. Older than a comprable individual
1. More work experience than a comprable individual
1. Timing of work experience at an unfortunate point in time

Effect of UI payment duration reform
• A one-week reduction in BPD leads to 1.32 days reduction in the unemployment duration
• The average unemployment spell length decreased by about 9 days
• This amounts to 37,5 % of the decline in spell duration in Germany since 2006

A simple search model
Behaviour changes as benefit expiry approaches
Objective function:(roughly following Mortensen 1977)
FOCs evaluated in the initial period of unemployment (U = UT):
2.
1.
c: search cost in units of consumption s: search intensity wR: reservation wage U: value func. of being unemployed b: benefitsλ(s): rate of job offer arrivals ( λ’>0 & λ’’<0 ) u: instantaneous utility W: value func. of working s*: threshold of search activity, below it a person is considered inactive
Stylised time pattern of the exit rate
T Time
Exit rate

Estimating the exit rateThe hazard rate is the probability that an individual leaves unemployment in a given time interval (months in this case):

Conclusions about spell duration
• Unemployment duration was reduced by 1.7 months
• The time to find a new job fell by 1.3 months
• But only 17% of the unemployed affected

Reply to questions:• Question: Maybe the affectedgroup takes different jobs compared to the unaffected(e.g. due to training differences among age groups). The common trend assumption might therefore fail.• Reply:
1. The responsiveness to shocks before 2006 can be tested directly. Such worries are unwarranted according to previous slides.2. For differential shocks that only occur after 2006 can only do indirect testing. Consider Industries with greatest share of job creation for the two groups. Four of the top five job creation industries are identical. No other industry creates more than 5% of jobs. Hence differential developments across industries are unlikely to bias the results.
