Norwegian prisons rehabilitate criminal offenders

August 24, 2016

The research project "The Social Costs of incarceration" is the largest study of imprisonment and return to a normal life that has ever been conducted in Europe.

In the study, researchers looked at prison sentences linked to recidivism. In addition, the researchers looked at the extent to which former inmates have returned to work. What makes the project unique is linking large administrative data sets to data sets from the courts.

They have done this to measure the effect of what happens when the criminals have received different penalties for the same offense because they randomly met different judges in court with different leniency towards incarcerating. In other words: if a judge incarcerates differently for the same offense, what will be the consequences for the offender in the long term?

"The results show that the Norwegian prison model with extensive use of labour training while serving time, gives surprisingly good results," says Professor Katrine Løken at the Department of Economics, University of Bergen (UiB), who led the research project.

The study is published as a Working Paper in Economics at the University of Bergen.

Work is the key

The effect of imprisonment on a criminal path is not well known. In Western countries there are major differences in the incarceration systems. In Scandinavian countries such as Norway, the prison system focuses on rehabilitation and job training.

If rehabilitation programmes in prison work, is your opinion that we should send more offenders to jail?

"Not necessarily. Work is the key to get out of a criminal pattern. We see that labour-programmes in prison give people opportunities, while those offenders that are not sentenced to prison, are more difficult to follow up," says Løken, adding:

"A relevant question is whether we should aim for full package of job-training outside prison. But research shows that work training outside of prison is more difficult to enforce. It appears that a certain element of coercion is needed to get offenders on a new track."

Katrine Løken stresses that the research does not take a stand on the principle of imprisonment, but simply says something about how prison is perceived for the individual, and shows the effects of different sentencing.

Opposite results in the US

The idea for the project came after researchers heard about a couple of American studies of imprisonment with similar research method. In one of the newer US studies,from Texas, they find however that time served in prison leads to relapse into crime and exclusion from working life. The Norwegian researchers were curious if they would find the same tendencies in Norway.

"But the main reason why we thought the area could also be interesting to study in Norway is the unique data sets that exist here. While the US study was only conducted in one particular state in the US, we could get a total overview of all convicts in Norway over a long time period," says Løken.

Unique Norwegian registry

In Norway there are data for the whole population from Statistics Norway (SSB). In addition there are data records of all criminals in Norway.

The researchers intertwined these datasets against the Norwegian legal data base "Lovdata" and could thus identify how different judges sentenced the same offense differently. Then they measured the effect of the prison sentence and whether it was conditional or unconditional, and saw how this influenced future criminal behaviour and attachment to the labour market.

"By focusing on the direct impact of a judge's sentencing, we ended up with a better set of data, which told us much more about the effect of prison than most previous studies have been able to," says Løken.
