|July 2020||"Quick Response" Economic Stimulus: The Effect of Small-Value Digital Coupons on Spending|
with , , : w27596
We study a new consumption stimulus model that leverages mobile payment platforms to dispense massive amounts of small-value, use-it-this-week-or-lose-it digital coupons. We evaluate the effects of one such program in a large Chinese city using novel data of mobile platform transactions of 1 million program participants. Exploiting participants’ rush to the first-come, first-served digital portal, we compare spending among those who barely won coupons to those who barely lost because of minor differences in the timing of their arrival at the portal. We find that coupons generate an immediate increase in weekly consumption among winners by $3 additional out-of-pocket spending for every $1 in government subsidy – representing an order-of-magnitude improvement in fiscal cost-benefit relative ...
|April 2019||What Does an Electric Vehicle Replace?|
with , : w25771
The emissions reductions from the adoption of a new transportation technology depend on the emissions from the new technology relative to those from the displaced technology. We evaluate the emissions reductions from electric vehicles (EVs) by identifying which vehicles would have been purchased had EVs not been available. We do so by estimating a random coefficients discrete choice model of new vehicle demand and simulating counterfactual sales with EVs no longer subsidized or removed from the new vehicle market. Our results suggest that vehicles that EVs replace are relatively fuel-efficient: EVs replace gasoline vehicles with an average fuel economy of 4.2 mpg above the fleet-wide average and 12 percent of them replace hybrid vehicles. Federal income tax credits resulted in a 29 percent...
