问题如下：
Bader then uses the Singer–Terhaar model and the final shrinkage-estimated VCV matrix to determine the equilibrium expected equity returns for all international asset classes by country. Three of the markets under consideration are located in Country A (developed market), Country B (emerging market), and Country C (emerging market). Bader projects that in relation to the global market, the equity market in Country A will remain highly integrated, the equity market in Country B will become more segmented, and the equity market in Country C will become more fully integrated.
Based on expectations for changes in integration with the global market, all else being equal, the Singer–Terhaar model implies that Bader should shift capital from Country A to:
选项：
A.only Country B B.only Country C C.both Countries B and C解释：
Correct Answer: B
Bader expects the equity market in Country C (an emerging market) to become more fully integrated with the global market while Country A (a developed market) remains highly integrated. All else being equal, the Singer–Terhaar model implies that when a market becomes more globally integrated (segmented), its required return should decline (rise). As prices adjust to a lower (higher) required return, the market should deliver an even higher (lower) return than was previously expected or required by the market. Therefore, the allocation to markets that are moving toward integration should be increased. If a market is moving toward integration, its increased allocation will come at the expense of markets that are already highly integrated. This will typically entail a shift from developed markets to emerging markets.
中文解析：
Bader预计，C国(新兴市场)的股票市场将更加充分地与全球市场整合，而A国(发达市场)仍将保持高度整合。在其他条件相同的情况下，辛格-特哈尔模型表明，当一个市场变得更加全球一体化(细分)时，其要求回报应该下降(上升)。当价格调整到更低(更高)的要求回报时，市场应该提供比之前预期或市场要求更高(更低)的回报。因此，应该增加对正在走向一体化的市场的分配。如果一个市场正在走向一体化，其增加的分配将以牺牲已经高度一体化的市场为代价。这通常需要从发达市场转向新兴市场。
- 老师，我解题的思路是：应该在B和C中选择expected return更高的行业进行投资；由于B会越来越segmented，未来补偿这一风险，B的expected return会更高，所以选B
麻烦老师指出一下这个思路的问题
- 想请问老师，如何确定解题时应该从expected return的静态数值上分析，还是从expected return作为折现率的动态变动上来分析呢？
