Common questions

Does Graphl cover both SL and HL IB Economics?

Yes. The SL core (markets, AD-AS, trade, development) and the HL extensions (theory of the firm, Phillips curve, multiplier, Marshall-Lerner and the J-curve) are all interactive models here, labelled by difficulty tier.

Which diagrams appear most in IB Economics Paper 1?

Externalities with welfare loss, AD-AS with output gaps, the Lorenz curve for inequality, and the tariff diagram are the perennial Paper 1 and Paper 3 favourites. All four are on this page with graded practice.
