Airbnb Business Model and Monetization Questions

Airbnb's marketplace business model and how it monetizes a two-sided host/guest network: the service-fee structure charged to hosts and guests, the historical shift in take rate and fee allocation, revenue diversification beyond core stays (Experiences, Airbnb-branded co-hosting, longer-term stays), host incentive and retention mechanics (Superhost tiers, AirCover, host guarantee costs), pricing and dynamic-fee mechanics, unit economics of the marketplace (host acquisition cost, guest lifetime value, take-rate trends, contribution margin per booking), the trust and safety cost base that underwrites the fee, and how regulatory pressure (short-term rental restrictions, occupancy tax remittance, international market entry rules) constrains pricing and expansion strategy.
