April Rinne, Sharing economy expert and advisor, has traveled to almost 100 countries and worked in around 50 of them. “None define sharing the same way,” Rinne says, though she adds that the most general definition of the sharing economy involves sharing under-utilized assets, spaces, and skills. Rinne believes that there’s been a global pendulum shift in the last 18 months, one that led to an increased awareness—if not quite increased expertise—of the sharing economy among policymakers. And while the United States, and the Bay Area in particular, has maintained its role as a leader in technological innovation, it lags behind when it comes to policy innovation. Rinne discussed global policy innovations related to the sharing economy, like the UK’s sharing economy trade association, and Seoul’s Sharing City government department.
