Employment, Mobility, and Active Labor Market Programs
Fredriksson, Peter; Johansson, Per - 2003
Using a unique micro panel data set we investigate whether active labor market programs improve employment prospects and increase mobility in the longer run. We consider two prototype programs: job creation programs and training programs. We find that both programs reduce the chances of finding...

Virtues of SIN: Effects of an immigrant workplace introduction program
Åslund, Olof; Johansson, Per - 2006
We evaluate an immigrant workplace introduction program aimed at helping individuals considered employable but at the same time expected to experience substantial difficulties in finding work. Using supported employment methods, the SIN program may influence outcomes through several channels. We...

Using internal replication to establish a treatment effect
Johansson, Per - 2006
In many cases assignment to a treatment may affect concomitant variables. I show how a concomitant variable can be used to corroborate evidence from an observational study. In the observational study two types of training programs are compared. One program is part of regular Swedish labor market...

Testing for nonparametric identification of causal effects in the presence of a quasi-instrument
de Luna, Xavier; Johansson, Per - 2012
The identification of average causal effects of a treatment in observational studies is typically based either on the unconfoundedness assumption or on the availability of an instrument. When available, instruments may also be used to test for the unconfoundedness assumption (exogeneity of the...
