Consider Tesla, which produces electric cars. In the long run, cars can be made using a combination of labor and capital. Explain how Tesla’s labor demand curve would change in each of the following situations. (a) Labor and capital are complements, and the price of capital in-creases (b) Labor and capital are gross substitutes, and the price of capital decreases (c) Universities in Texas and California (where Tesla produces cars in the US) improve the quality of their advanced engineering programs. Over the next several years, the productivity of mechanical engineers hired by Tesla increases.

Solutions

Expert Solution

(a) When Labour and Capital are complements and the price of capital increases.

Labour and capital are complements it means that they have to be used together in the production. If the price of capital increases, then the demand for both capital and labour will decrease since they are used in the production together.

We can see that the demand curve for labour and capital shifts down to a new equilibrium E1.

(b) When Labour and Capital are gross substitutes, and the price of capital decreases.

This means that the capital and labour can used as a substitute for eache other. One can be use instead of the other. When the price of the capital decreases, then the production firm will use more of capital and less of labour for more output. So the demand for labour will go down. The demand for capital goes up and the production firm increases its usage of capital.

(c) Universities in Texas and California improve the quality of their advanced engineering programs. Over the next several years, the productivity of mechanical engineers hired by Tesla increases.

The production firm will invest more in capital and less of labour for more output since the productivity of mechanical engineers hired by Tesla increases. So the demand for labour will go down. The demand for capital goes up and the production firm increases its usage of capital.

Tesla Motors is a California-based company that designs, manufactures, and markets high-performance electric cars. The company's first vehicle to hit the market was the Tesla Roadster, a sporty two-seater. Tesla's performance specifications are truly impressive. For example, the Roadster can accelerate from 0 to 100km/h in under 3.8 seconds. This type of acceleration is comparable to many high-performance Ferrari combustion engine models. The Tesla luxury sedan Model S and sport-utility vehicle Model X have also received accolades for artful design...

1. Consider the case of The Electric Company which produces electricity in New York State. The average monthly demand curve for the firm can be represented by P=65-Q where Q represents the quantity of electricity produced, in megawatt-hours (mwh) and P is measured in cents. Their marginal costs can be represented by MC=5+0.5*Q. Please provide graphs to accompany your analysis. b. In the case above, is this profit-maximizing outcome efficient?  If not, calculate any deadweight loss.
