Suppose you are measuring annual Australian GDP by adding up the final value of all goods and services produced in the economy. Determine the effect of each of the following transactions on GDP:
a. You buy $\$ 10$ worth of potatoes from a market gardener, which you cook and eat at home.
b. A restaurant buys $\$ 10$ worth of potatoes from a market gardener.
c. Qantas buys a new jet from Boeing.
d. The Australian government buys a fleet of cars from Holden for $\$ 1$ million.
e. The government sells one of these cars to you for $\$ 50000$.
3. During a given year, the following activities occur:
i. A silver mining company pays its workers $\$ 200000$ to mine 75 kilograms of silver. The silver is then sold to a jewellery manufacturer for $\$ 300000$.
ii. The jewellery manufacturer pays its workers $\$ 250000$ to make silver necklaces, which it sells directly to consumers for $\$ 1$ million.
a. Using the 'production of final goods' approach, what is GDP in this economy?
b. What is the value added at each stage of production? Using the value added approach, what is GDP?
c. What are the total wages and profits earned? Using the income approach, what is GDP?
