Final answer:
An Integrated Asset Management System helps managers and policy makers understand the impacts of their decisions and enables investors to have liquid assets and professionally managed funds, although diversified portfolios may be expensive.
Step-by-step explanation:
The benefits of an Integrated Asset Management System are manifold, offering significant advantages to managers and policy makers. For example, tools like InVEST provide integrated insights into the effects of resource management decisions on the economy, human well-being, and the environment.
In the context of mutual funds, an integrated approach means assets are highly liquid, and the funds are professionally managed, allowing investors to save time and effort. Moreover, diversified portfolios can lead to increased expected returns without bearing substantial risks, though they may be costly. Such systems help in answering key questions like whether a diversified savings and investing portfolio ensures economic success.
