Randomly deciding which institutions different countries have – there is a huge literature about the importance of institutions, but they are intertwined with so many other things about cultures and countries it is hard to know specifically what matters…
Randomly experimenting with different tax and expenditure policies – let’s solve the debate once and for all!
Industrial policy experiments – should countries be trying to follow the model of Korea/China and develop through light manufacturing and heavy state intervention, or should they be trying to develop their natural resources more, and developing more like Australia/Chile?
I’m not sure what would be the most interesting micro experiments – many of the key things we’d actually like experimental evidence for we are starting to see experiments providing it, or at least I see hope that we could in the future. What do our readers think, if you had your own planet to experiment on, what experiment would benefit economics most?
I would take a pick from the science experiments and do a brain sampling of Keynesians vs Free Market advocating econ0mists. Like in the science experiment, researchers would obtain brain cells just as a surgeon does when conducting a biopsy. Collaborating with the science researcher, the economic researcher will then try and understand the neurological differences between the two distinct species of economics.
