We implement a series of randomized experiments in a total of 8 annual surveys representative of the German electorate (N>25,000). We experimentally replace regular upfront payments by deferred income-contingent payments. 2/4

Extremely saddened to learn about the passing of Jon Temple. He was a leading thinker on the economics of growth, and such a decent person. Here’s a few fond memories of our interactions, for which I’ll always be profoundly grateful: www.linkedin.com/feed/update/... R.I.P., dear Jon.
