Answer:
Change in US external wealth between periods T and T +1 in dollars = -$100
Explanation:
Since nothing else changes, this implies that the exchange rate per yen is $0.01 in periods T and T +1. Therefore, we have:
Value shares of Sonic in period T in dollar = Number of shares of Sonic bought in period T * Price per share of Sonic in Yen in period T * Exchange rate per yen in periods T = 100 * 700 * $0.01 = $700
Value shares of Sonic in period T+1 in dollar = Number of shares of Sonic in period T+1 * Price per share of Sonic in Yen in period T+1 * Exchange rate per yen in period T+1 = 100 * 600 * $0.01 = $600
Change in US external wealth between periods T and T +1 in dollars = Value shares of Sonic in period T+1 in dollar - Value shares of Sonic in period T in dollar = $600 - $700 = -$100
Answer:
See below
Explanation:
Marginal cost is the expense associated with the production of an extra unit. It is the cost incurred by a business should it produce one more unit.
Marginal benefit is the gain resulting from the sale of one more output. It is the revenue earned from the sale of an extra unit of output.
Marginal benefit is compared to marginal cost to determine if producing and selling an extra unit is profitable or not. If the marginal benefit is greater than marginal cost, selling an extra unit is profitable. In making economic decisions, production should continue as long as the marginal benefit is greater or equal to marginal cost. It must stop when marginal cost is more than marginal benefit.

Answer:
3. Correctly ignored a sunk cost
Explanation:
Sunk costs refer to those costs which have been incurred in the past, which are non recoverable and which have no current or future benefits.
Sunk costs are considered as irrelevant for decision making process as they do not relate to current period and have no future implications. For example, research and development expenditure incurred in the past represents a sunk cost.
In the given case, the ticket for opera was already purchased for $100 which can now neither be recovered nor transferred. Thus this cost is irrelevant for decision making as expenditure has already been made. When Shen decided to go for a party instead of the concert, Shen has correctly ignored a sunk cost.
