Ah, so it's necessarily a compounding effect across the supply chain, then? E.g. assuming 2.5% price increases: energy costs are 1.025x as expensive > fertilize

Ah, so it's necessarily a compounding effect across the supply chain, then? E.g. assuming 2.5% price increases: energy costs are 1.025x as expensive > fertilizer is now (1.025^2)x as expensive > crops are (1.025^3)x > beef is ^4 > patties ^5 > so now McDs pays 1.025^5 = 13% more on beef, pushing prices up >13% of their avg previous beef cost. The argument is that it could easily get above 50% given cycles in the economy. Ok, makes sense - thanks
