Answer:
Increase quantity to where AC = MC = D=AR=MR
Explanation:
A perfectly competitive market is where there are many firms in the industry producing homogeneous products. There is ease of entry and exit into and out of the market. They are price takers and earn normal profits in the long-run. In order to maximize profits, a firm in a perfectly competitive industry should produce an the quantity where its average cost is equal to marginal cost when AR = MR = D. In other words, when the AC and MC curves intersect with AR = MR = D curve.
<em><u>Please refer diagram</u></em>
The firm is currently producing at a point where AC > MC at quantity 1000. In order to reach AC = MC, the firm has to increase its quantity to Qe. As it increases quantity, although marginal cost increases, average cost falls because now fixed costs are spread over a larger quantity of output.
At Qe, the three curves intersect and is the point where this firm can maximize its revenue (Price = Pe). At a price higher than this, it would lose customers since there are many others producing the same product and customers can easily shift to another.
Answer:
i) the intercept is - 124.84 and it is negative because when the income of individuals is zero their consumption = - 124.84 (i.e. consumer borrows 124.84 ).
ii) $25465.16
iii) attached below
Explanation:
Given that the equation is
^cons = -124.84 + .853 * inc
<u>i) Interpret the intercept in this equation and comment on its sign and magnitude</u>
intercept : the intercept is - 124.84 and it is negative because when the income of individuals is zero their consumption = - 124.84 (i.e. consumer borrows 124.84 ).
The slope = .853 is positive because consumption is will increase by 0.853 whether the income rises or decreases by the value of 1
<u>ii) Determine the predicted consumption when family income = $30000</u>
^cons = -124.84 + 0.853 * ( 30000 )
= 25465.16
hence when family income = $30000 the predicted consumption = 25465.16
<u>iii) Draw a graph of the estimated MPC and APC ( inc on the x-axis )</u>
MPC = 0.853 ( constant )
APC = Cons / inc
attached below is the required graph
