Economists Steven Levitt John List compete for the affections of fed-up JMCs looking to either renovate or sell their JMP.
Levitt transforms their no good JMP by adding a weak instrument while List works to find them a new topic involving an experiment.
At the end of each hourlong episode, the JMCs decide if the changes designed by Levitt are enough for them to stay with their current JMP, or if the new topic List has found better suits their needs. So whether they Lev-itt or List it, the JMCs come out on the bottom.
