A standard
unit of account is used to rank different organizations, activities,
and goods and services, using a single standard. In modern economies,
money in the form of currency serves the role as a standard unit
of account with respect to all market activity. It allows for the
price of goods and services to be comparable.
In Accounting, a standard unit of account allows for the ranking
of the economic status of different organizations and activities.
This serves to allocate scarce resources in a way most beneficial
to an economy. The use of a unit of account in financial accounting
allows investors to invest capital into those companies that provide
the highest rates of return. The use of a unit of account in managerial
accounting enables firms able to choose between activities that
yield the highest profit.
In Economics, a standard unit of account is used for statistical
purposes to describe economic activity. Indexes such as GDP and
the CPI are so broad in their scope that compiling them would
be impossible without a standard unit of account. After being
compiled, these figures are often used to guide governmental policy;
especially monetary and fiscal policy.
In calculating the Opportunity Cost of a policy, a standard unit
of account allows for the creation of a composite good. A composite
good is a theoretical abstraction that represents an aggregation
of all other opportunities that are not realized by the first
good. It allows an economic decision's benefits to be weighed
against the costs of all other possible goods in that society,
without having to refer to any directly. Often, this is most easily
accomplished with money.
