这题做对了 但是两个理论的知识点在哪里？还有没有一起提到的其他理论？

问题如下：

3. The least appropriate factor used to describe the type of models mentioned in Statement 3 is:

选项：

inflation.

price level changes.

risk premium adjustments.

解释：

C is correct.

Risk premiums are more closely associated with the portfolio-balance approach. The portfolio balance approach addresses the impact of a country’s net foreign asset/liability position. Under the portfolio balance approach, investors are assumed to hold a diversified portfolio of assets including foreign and domestic bonds. Investors will hold a country’s bonds as long as they are compensated appropriately. Compensation may come in the form of higher interest rates and/or higher risk premium.

考点： Monetary models

解析： Statement 3中关注涉及的方法是 Monetary models，该种方法关注点正是货币发行量、物价水平以及通货膨胀。所以选项A，B的说法都是正确的。
但是 risk premium adjustments并非 Monetary models的关注点，它是portfolio-balance approach的关注点。portfolio-balance approach下，人们持有多种资产的自合。那么投资者便会关注每种资产能否为其提供足够的风险溢价补偿，补偿的形式集中于较高的利率水平，以及较高的风险溢价。所以C选项的说法是错误的。
