Relationship between marginal output and STC in microeconomics In the stage of diminishing marginal production, STC (.) A. Increasing speed B. The increasing speed decreases C. Decreasing speed rise D. Decreasing speed
Let the variable element be x and the price of variable element X be w
STC=wf(x)+FC
MC=wdf(x)/dx=w*MP
MP decreases, which means MC increases, so STC increases rapidly
Suppose that there are 500 identical manufacturers in a perfectly competitive industry, and the cost function of each manufacturer is STC = 0.5q square + Q + 10, find the supply function of the market 2. Assuming that the market demand function is QD = 4000-400p, find the market equilibrium price
Perfect competition, P = MC, the derivative of the cost function * 500 is the supply function
It's just the same column as the supply function of 1
Given STC = Q2 + 5q + 4, find the short-term supply function and profit function of the plant
The short-term supply function should be its derivative
SSF=2Q+5
Profit = 2q + 5 - (Q ^ 2 + 5q + 4) = - Q ^ 2-3q + 1
2. Suppose a monopolist's product demand curve is: P = 50-3q, and the cost function is TC = 2q, so as to find the output, price and profit when the monopoly enterprise has the maximum profit
Marginal cost MC = cost (TC) 'q = 2, (conditional Mr = MC) total income tr = P * q = (50-3q) * q
Mr = (TR) 'q = 50-6q = 2, q = 8 (output)
Price P = 50-3q = 50-3 * 8 = 26
Profit π = P * Q-Tc = (50-3 * 8) * 8-2 * 8 = 192
Short term cost function: STC = 0.04q cubic -0,8q find the minimum average variable cost value
First list the average cost function, find the first derivative, get two solutions, and substitute them into the second derivative respectively. If the second derivative is greater than zero, it is the minimum point. If the second derivative of the two solutions is greater than zero, substitute the two solutions into the original function respectively to get the minimum value and the problem solution
