主題：顛覆者：特斯拉Model 3發布會的影響研究

講座簡介：

As a game changer, the arrival of the Tesla Model 3 on March 31, 2016, significantly affected the market for combustion engine sedan and hatchback cars, rather than cars with other body types. Using eBay used car auction data, we examine the extent to which the Model 3 announcement impacts the prices and transaction quantities of these vehicles. Our analysis reveals that while the average auction final price decreases significantly, the transaction quantity remains unaffected. We further find robust evidence indicating that the price decline primarily results from a decrease in buyers’ willingness to pay, approximately 6 percent, driven by lowered expectations of the cars’ future residual values. Our welfare analysis suggests that while the market maintains allocative efficiency, there is a redistributive effect that the decrease in willingness to pay entirely translates into lower seller surplus, and consequently, sellers bear almost all the welfare loss. The asymmetric welfare impact highlights sellers’ limited ability to adjust supply in the short run within the used car market.
