IELTS Reading: Summary Completion (from text)

The 'sharing economy' — a broad term encompassing digital platforms that facilitate peer-to-peer exchange of goods, services, skills, or spaces — has grown from a niche concept into a multi-trillion-dollar global industry over the past fifteen years. The concept draws on older traditions of lending, borrowing, and community exchange, but digital technology has dramatically reduced the transaction costs that previously made such exchanges impractical at scale: it is now possible to find, vet, coordinate, and pay for a transaction with a stranger anywhere in the world in minutes. The most commercially significant sharing economy platforms include Airbnb, which facilitates short-term rental of private residential space, and Uber and its competitors, which connect passengers with drivers using their own vehicles. Both have achieved enormous scale — Airbnb has listings in over 220 countries and Uber operates in 10,000-plus cities — and both have disrupted incumbent industries (hotels and taxis respectively) by offering services that traditional providers cannot easily replicate: a personalised, non-standardised experience, flexible supply that scales rapidly with demand, and prices that are structurally lower because platform workers are classified as independent contractors rather than employees. This legal classification is simultaneously one of the sector's defining innovations and its most contested feature. Classifying workers as independent contractors rather than employees allows platforms to avoid the costs associated with employment: minimum wages, social security contributions, paid leave, sick pay, and unfair dismissal protections. Critics argue that in practice, gig workers have little genuine autonomy — they work predominantly for one or two platforms, their working conditions are determined by algorithmic management systems, and their income is often precarious and falls below national living wages when on-costs such as vehicle depreciation and insurance are accounted for. A series of legal challenges in multiple countries has resulted in some courts reclassifying gig workers as employees or as a new intermediate category. The environmental claims of the sharing economy require scrutiny. The argument that platforms such as Airbnb and Uber promote more efficient use of underutilised assets — spare bedrooms and private cars that would otherwise sit idle — is empirically questionable. Research consistently finds that Airbnb typically adds supply to tourist accommodation markets rather than substituting for hotels, and that Uber's introduction into urban markets has been associated with increases in total vehicle kilometres travelled, as deadheading (driving without a passenger) and induced demand offset efficiency gains.
