well, i want to see this forum's opinion on PPC shifters( what shifts the frontier of a production possiblity curve)
Is trade a Shifter? Or a component~~(causes the shifters)?
so far, i categorize the shifters as; more resources, better resources, better technology.
TY
I think trade could be a shifter if it is providing more resources for production. Exporting of goods would not be a shifter.
