An earthquake in Finland

The Finnish experiment of 2017–18 is a crucial test case. It provides one of the most robust experimental tests of a universal basic income (UBI) in the context of an advanced industrialised society. And it is a real milestone, since it represents a nonutopian approach to UBI that can be palatable to middle class voters. But its partial success is also a partial failure. Although it is too early to render judgement, the Finnish case shows that there are many obstacles for the successful implementation of theoretical models. Experiments often fall short of the ideal experimental conditions. This speaks against taking too optimistic a view on the next steps.
