Basic Economic Concepts
If climate change causes longer growing seasons for corn, how might this affect the corn supply curve?
The curve may move downward as prices drop due to greater crop yields.
The curve could shift left due to shorter growing seasons decreasing quantities supplied.
The curve may shift right because longer growing seasons could increase quantity supplied.
The curve stays the same since climate change doesn't impact agricultural production.

In an economy with fully flexible wages and prices experiencing a negative supply shock, what could be the central bank's best course of action if it wishes to stabilize both prices and output without exacerbating future volatility?
