In an effort to boost COVID-19 vaccination rates, mobile vaccination units were rolled out in late 2021. This strategy proved successful: the number of vaccinations administered was between 1.1 and 14.5 times higher in neighbourhoods on the days they were visited by mobile units. The units were more effective in rural areas than in urban settings. In addition, they proved to be more effective than average in neighbourhoods with a higher proportion of SGP voters and still effective, although to a…

In a series of field experiments, six municipalities investigated whether a different approach in social assistance could get more people into work. The study focused on the effects of an exemption from the obligation to seek work, more intensive counselling or higher earnings disregards for additional income.

A circular business model promotes reuse of products and materials. A case in point is a model where consumers return their jeans to the manufacturer after use. Which circular business model characteristics are consumers willing to accept right now, and what do they refuse?

Why this experiment was conducted: to promote the circular…

Why this experiment was conducted: teacher shortages The government has identified significant staff shortages in primary and secondary education. It is…
