Matt Tarduno @tarduno.bsky.social · 12/05/20267/ A high-level takeaway of this work is that the shape of the joint distribution of demand isn't sufficient to determine the gains from bundling -- the location matters too (i.e., are the "goods" commonly adopted or not?) 100 0
Matt Tarduno @tarduno.bsky.social · 12/05/20266/ - Simulations suggest modest gains from bundling EVs and heat pumps - Bundling does little for EV + rooftop solar subsidies - Data from an Indonesian CCT suggest that even though WTP is positively correlated in that setting, CCTs would be less cost-effective if unbundled! 100 0
