Economic methodology and the economic problem Flashcards
why is economics a social science
it looks at the behaviour of humans ethier as individuals or as organisation and how they use scarce resources
economic methodology

PPF
production possibility frontier shows the options that are available when you consider the production of two types of goods
trade off

PPF graph
all points on a PPF are efficient,
points outside a PPF arent achievable,
points inside a PPF are productively inefficient
Opportunity cost
