Question

For each of the following events, identify which of the determinants of demand or supply are affected. If demand is unaffected by this event because it creates only a supply change, select the "None" option under the "Demand Determinant" column. Similarly, if supply is unaffected by this event because it creates only a demand change, select the "None" option under the "Supply Determinant" column. Event Demand Determinant Supply Determinant People decide to have more children. A strike by steelworkers raises steel prices. Engineers develop new automated machinery for the production of minivans. The price of sports utility vehicles rises. A stock-market crash lowers people's wealth.

Answer 1

Answer:

(1) Demand Determinant - No. of buyers

Supply Determinant - None

When people decided to have more children then this will result in more number of buyers. This will affect the demand for a particular good and shifts the demand curve towards right.

(2)Supply Determinant - Input prices

Demand Determinant - None

Steel is an input for the firms and if there is an increase in the price of steel then as a result cost of production increases which results in lower supply for their product.

(3) Supply Determinant - Technology

Demand Determinant - None

New technology will increase the productivity of the firms and hence, increase the supply of the products.

(4) Demand Determinant - Price of substitute or complimentary goods

Supply Determinant - None

If the price of substitute good rises then as a result demand for minivans increases. This will shift the demand curve rightwards.

(5) Demand Determinant - Income

Supply Determinant - None

Decrease in the wealth of the consumers will result in lower demand for the minivans. Therefore, demand curve shifts leftwards.
