Temporal Analysis
Understanding how economic networks evolve over time is crucial. We use Hasse Diagrams to visualize the stability and hierarchy of these networks.
What is a Hasse Diagram?
A Hasse Diagram is a graphical representation of a partially ordered set (poset). In our context, we use it to show the subset relationships between monthly network states.
Month AMonth B
Month B is a subset of Month A
If Month B appears below Month A in the diagram, it means the economic connections in Month B are a strict subset of those in Month A, indicating a contraction in market integration.
Network Density Over Time
This chart shows how network density and average price similarity evolved over time for the Food Staples & Grains category. Higher density indicates stronger market integration across cities.
