Layard & Clark on "why psychological therapy would cost nothing"

From voxeu
"Mental illness is the main sickness of the working age population with economic costs around 8% of GDP. This column, based on the authors’ recent book, discusses the effectiveness of a large programme of psychological therapy, launched in England in 2008. The savings due to welfare benefits, extra taxes, and physical healthcare outweigh the costs of the programme. In this case, psychological therapy costs nothing."
