Episode notes
Smartphones Enable People Marketplaces
- People marketplaces connect buyers to independent contractors to provide services using smartphones as the enabler.
- The smartphone's GPS and compute make distributed labor scheduling and logistics tractable at scale.
Real-World Marketplaces In Action
- Jeff uses Lyft, Homejoy, and restaurant delivery as concrete examples of people marketplaces in action.
- He describes tracking drivers via GPS and using algorithms to optimize assignments and next orders for efficiency.
Virtual Model Vs. Parallel Supply Chains
