Industries with network externalities and strong complementarities may exhibit multiple equilibria. I examine whether direct government provision of network infrastructure — a Big Push — can remedy this inefficiency. Using EV registration and charging transaction data from 2017–2023, I build a structural model of vehicle demand and charging behavior, in which consumers choose an EV model and derive utility from performing trip, which is function of the charging network quality. I decompose the Big Push into two components: a coordination effect and an externality effect. I find that the coordination effect — shifting the economy from the low-adoption to the high-adoption state — increases EV adoption by 140%, while the externality effect raises adoption by an additional 50%. The latter arises from the placement of chargers at critical connector nodes that would otherwise be unprofitable. As the network grows from about 300 to 1,000 stations, government provision crowds in private investment in the network core while crowding out investment at the periphery. Overall, the policy is highly effective, generating $11 billion in consumer value and $2,7 billion in climate benefits from a $185 million investment. This paper provides the first empirical evidence that direct public provision of network infrastructure can resolve coordination failures.
