Answer:
Explanation:
a. QXd = 1,200 – 3PX – 0.1PZ
Pz = $300 and Px = $140, plugging the values, we get,
Qx = 1200 – 3*140 – 0.1*300.
Qx = 750 units.
Elasticity of demand = \deltaQx/\deltaPx * Px/Qx.
\deltaQx/\deltaPx = -3.
E = -3 * 140/750.
E = -0.56
The elasticity of demand is INELASTIC because the absolute value of elasticity is less than one. If the firm charges a price below $140it might lose out in revenue because the percentage change in demand is less than the price.
b. Px = $240, substituting this into the equation we get
Qx = 1200 – 3*240 – 0.1*300
Qx = 450 units.
E = -3 * 240/450.
E = -1.6
The demand is elastic because the absolute value is less than one. If the firm charges a price above $240 it might lose out on its revenue because the percent change in demand is more than the price.
c. Cross price elasticity of demand Es = \deltaQx/\deltaPz * Pz/Qx.
\deltaQx/\deltaPz = -0.1
Es = -0.1 * 300/750.
Es = -0.04
The goods are complements of each other. As the price of one increases, the demand for other would fall, and vice-versa is true.
Yes because without unions, the head of the company can create working conditions and pay scales that satisfy themselves and barely pass government regulations. An example would be undocumented workers who work non union jobs and have horrible working conditions. They cannot report due to the fact that they are undocumented. A union creates a work environment and a solid fall back for employees. Employees have the union to back them up and protect them from an “unfair boss”. Without unions the workers have no ground to stand as an employee base.
Answer:
D. no control over either the price of pretzels or the wage it pays to its workers.
Explanation:
A competitive market is characterised by many firms that are price takers. Firms that are price takers have no influence over the price they charge for their products; prices are set by the forces of demand and supply.
If the market for pretzels are competitive, the firm cannot set the price for pretzels. If the pretzel stand owner increases the price for pretzels, consumers patronize other pretzel stand owners. There would be no incentive for the pretzel owner to reduce its cost because the pretzel stand owner would be reducing its revenue and reducing its profit
If the market for pretzel makers is competitive, firms have no influence on wages that can be paid to workers.Wages are determined by the forces of demand and supply. If wages are cut, workers move to other firms. There would be no incentive to increase wages because it would increase cost and reduce profit.
