Answer:
A. Matched Samples
Explanation:
Matched samples is a situation whereby participants are paired, sharing every other characteristics except the one under investigation. The idea behind this is to have more control over unwanted variables. In this case, the study is measuring two production methods and in order to control the unwanted variable and leave only the characteristic or variable under investigation which is the production method, the two method is carried out by the same workers each.
Answer:
C) A firm's marginal cost curve is equal to its supply curve for prices above average variable cost
Explanation:
A perfectly competitive firm maximizes its profit when its marginal cost = marginal revenue. In the short run, it will continue to produce even if the marginal revenue is lower than its marginal costs, as long as the marginal costs are ≥ average variable costs.
Therefore, all perfectly competitive firms should supply products or services following its marginal cost curve as long as the price ≥ average variable costs.
Answer:II) More risk-averse investors will invest less in the optimal risky portfolio and more in the risk-free security than less risk-averse investors. III) Investors choose the portfolio that maximizes their expected utility.
Explanation:The capital allocation line is a line created in a graph by investors in an economy to display or identify the potential risks involved in taking risky decisions. This line is one the determining factors to ensure that the investor has adequate knowledge about the risky nature of a capital investment.
Investors generally choose portfolios that guarantee maximum profits with reduced chances of loss. More risk averse investor will choose or opt for less risky portfolio.
Answer:
(a) Excess reserves = 200
(b) Monetary base (B) = 900
(c) Money multiplier = 10
Explanation:
Assuming that the required reserve ratio (missing in the question) is 0.1:
(a) Excess reserves = Reserves - Required reserves
Reserves = 400
Required reserves = Deposits x Required reserve ratio
= 2000 x 0.1
= 200
Hence, Excess reserves = 400 - 200
= 200
(b) Monetary base (B) = Reserves + Currency
= 400 + 500
= 900
(c) Money multiplier = 1 / Required reserve ratio
= 1 / 0.1
= 10
