Question

The following calculator shows the supply curve for sedans in an imaginary market. For simplicity, assume that all sedans are identical and sell for the same price. Two factors that affect the supply of sedans are the level of technical knowledge-in this case, the speed with which auto-manufacturing robots can fasten bolts, or "robot speed"-and the wage rate that auto manufacturers must pay their employees. Initially, the graph shows the supply curve when robots can fasten 2,500 bolts per hour and autoworkers earn $25 per hour. Use the calculator to help you answer the following questions. You will not be graded on any changes to the calculator; it's just here to help you answer the questions that follow. Tool tip: Use your mouse to drag the green line on the graph. The values in the boxes on the right side of the calculator will change accordingly. You can also directly change the values in the boxes with the white background by clicking in the box and typing. When you click the Calculate button, the graph and any related values will change accordingly.

Suppose that the price of a sedan decreases from $23,000 to $18,000. This would cause the sedans to decrease, which is reflected on the graph by a movement along the supply curve. quantity supplied of Following a technological improvement-for example, an increase in the speed with which robots can attach bolts to cars-there is a rightward shift of the supply curve, because the technological improvement makes cars less expensive to build

Explanation / Answer

Yes. The answers are correct.

1) there is quantity supplied decrease and not just supply because supply is for a bigger picture while here we are only concerned with the cahnges in quantity supplied due to change in price.

2) since own price changes thats why movement along the curve an dnot any shift of the supply curve.

3) Rightward shift because of incraese in output due to technological improvement

4) As supply curve shifts to the right. This means that each output level is available at lesser price.
