Course Description

Overview

Explore the dynamics of optimal growth in two-sided markets through this 52-minute lecture by Garret Van Ryzin from Cornell Tech. Delve into platform markets, examining key questions surrounding the "blitzscaling" phenomenon and its justification. Analyze the output model, including Uber's napkin diagram, pricing strategies, and buyer/seller surplus. Investigate the growth model, market size, and balance reformulation, comparing faster and slower growth scenarios. Examine the infinite horizon problem, growth path constraints, and optimal balance. Discover driving forces in increasing returns to scale markets, stationary solutions, and optimal growth policies for both increasing and decreasing returns. Conclude with a numerical example, matching function analysis, and a brief look at work-in-progress on oligopoly growth in platform markets.
