What's the difference between a contraction in supply and a decrease in supply?

Contraction: prices fall so a movement along the curve.

Decrease: a non-price factor changes so the curve shifts left.

M = 30; X = 40; G = 70; S = 20; T = 50; I = 60.

This economy is... <shrinking, growing, equilibrium>?

Growing

300
The outcome of production not paid for by consumers or producers is known as an...

externality

Three features of a trough period are...

What happens to demand for Adidas shoes when the price of Nikes drops?

Why?

Demand for Adidas will decrease as consumers prefer to purchase Nikes which are less expensive. 

300

Apart from price, what else affects supply? How?

400

In Year 1, the economy's GDP was $120,500.

In Year 2, it was $138,400.

14.85%

400

The roles of the government in the circular flow model are....

Taxing and spending

400

Explain how and when inflation happens.


Inflation happens in a boom because there is too much aggregate demand for the limited supply. Aggregate demand is high due to higher incomes for households and higher profits for firms leading to increasing investment. This causes prices to increase. 

400

What happens to demand for batteries when the price of kid's toys increases? Why?

Demand for batteries should decrease because there will be fewer children's toys purchased. If people aren't buying the toys, they don't need as many batteries. 

400

How is the goal of the firm sector different to the goal of the household sector?
