This work studies the impact of SNCF strike from April to June 2018 on the demand and
supply of the ridesharing market. Using detailed information available through BlaBlaCar
official API, we are able to construct the the market supply curve as well as observed market
demand curve by transaction records. We find that total transaction payment increased by
37% on an average strike day comparing to an average non-strike day, while market supply
increased by only 9%. We then estimate the elasticity of demand by using the relevant price
ranges on the observed market demand curve, taken into consideration of the influence of
default price on market demand. We conclude that BlaBlaCar generated additional 0.48 -
2 million, or 2.30 - 9.78% of the loss of SNCF, consumer surplus on an average strike day,
showing substantial substitutions between SNCF and BlaBlaCar.
