Estimating the potential increase in consumer welfare from the introduction of Super Wi-Fi services in Korea

“…It models the competition between secondary users as a noncooperative game, as in Shin (2011, 2013), and finds the Nash equilibrium at the point the database operator maximizes its profit.

In the simulations, they observe a generic tradeoff in which the trade facilitation including transaction, brokerage, and auction costs increase as the lease time shortens while finding that trade activity is insufficient if the lease time is too long.…”
