Focus question: How do households and firms decide to consume, save, and invest — and what makes those plans consistent in the goods market? This map lays out Module 3 (Abel Ch. 4) as a connected set of ideas. The three coloured spines are the three sections; the blue dashed cross-connections (revealed on demand) are where the chapter's deep structure lives — above all the real interest rate, the single price that ties saving, investment, and equilibrium together.
