The collaborative economy involves consumers granting temporary access to assets and resources owned by others. Some estimate the global sharing economy market size to be worth $533 billion in 2014, with significant growth predicted across demographics. Popular companies in this sector include Airbnb, valued at $10 billion, and Uber, valued at $17 billion. Economists believe the collaborative economy will have as big an impact as the Industrial Revolution due to new models of consumerism that focus on temporary access over ownership.
