What happens when economists go out at night in Singapore? Tonight I ran a small sample field experiment as John Ham and I took a river cruise around Singapore, then went out to a crab restaurant and then went on a long walk to watch the Marina Bay Sands laser and water show. I will submit my results to the QJE. The photo below gives you a glimpse at the city at night. I reject the null hypothesis that Singapore isn't great. Note the double negative!
