~What is the cost of economic growth?
Consume less now, then we can gain more in the future.
~Why do we trade and are there any gains to trade?
~The relationship between PPF, MB and MC.
Opportunity cost increases, MC increases
If we consume more production, then the satisfaction of the production
decreases, it means MB decreases.. MB means willingness
When MB is larger than MC, then it means that in the society, people are into
that kind of production, so we need to product more of it.
The point of MB=MC means allocative efficiency.
is an increase of GDP
How do we obtain more capital?
We need to sacrifice something this year, then we can gain more the next
year. (To shift the PPF curve out.)
Pizza ovens can not be used to produce more pizza ovens, but can be used to produce more pizzas.
