In models of international finance, what is the primary analytical advantage of assuming the existence of a single, 'representative' global investor?

Predicting Capital Flows with a Representative Investor

The Trade-off of a Simplifying Assumption in Global Finance

The assumption of a 'representative global investor' is used in economic models because it accurately reflects the identical and uniform decision-making process of every individual investor in the global market.

Consequences of a Simplifying Assumption in Financial Modeling

An economic model of international finance simplifies the behavior of all market participants by treating them as a single, rational decision-maker. Match each aspect of this modeling approach to its corresponding description.
