【Answer to question 1】C
【analysis】
C is correct. The market outcomes for two firms in a duopoly is shown in the diagram. The lower left hand quadrant is the Nash solution when there is no collusion. However, with collusion, if ArcCo shares at least enough of its profit in the bottom right quadrant to provide BatCo more than it would receive in the lower left, it will be the optimal solution for the pair: the maximum joint profits will arise where both firms charge high prices for the product.
B is incorrect; as per the explanation and exhibit above.
A is incorrect; as per the explanation and exhibit above.
【Answer to question 2】C
【analysis】
A is incorrect because it calculates the Laspeyres index. B is incorrect because it calculates the Paasche index.
成功=時間+方法，自制力是這個等式的保障。世上無天才，高手都是來自刻苦的練習。而人們經常只看到“牛人”閃耀的成績，其成績背后無比寂寞的勤奮。小編相信，每天都在勤奮練習，即使是一點點的進步，大家一定可以成為人人稱贊的“牛人”。
