Motivation
• Why bother studying the relationship between food prices in one market and another?
• Why bother studying the relationship between food prices at one level (e.g., farm-gate) and food prices at another level (e.g., retail)?

Determinants of marketing margins
• Spatial margins:– 1– 2– 3
• Vertical margins– 1– 2– 3
![Page 13: AAMP Training Materials Module 4.3: Marketing Margins & Marketing Costs T.S. Jayne (MSU) jayne@msu.edu](https://reader030.vdocument.in/reader030/viewer/2022032723/56649d015503460f949d4688/html5/thumbnails/13.jpg)
Why might margins ≠ costs
• Spatial margins:– 1– 2– 3
• Vertical margins– 1– 2– 3
![Page 14: AAMP Training Materials Module 4.3: Marketing Margins & Marketing Costs T.S. Jayne (MSU) jayne@msu.edu](https://reader030.vdocument.in/reader030/viewer/2022032723/56649d015503460f949d4688/html5/thumbnails/14.jpg)
What does it mean if:
• Spatial margins < transfer costs– 1– 2– 3
• Spatial margins > transfer costs– 1– 2– 3
