On the existence of macro variables and of macro relationships

Article Abstract:

Prevailing economic literature holds that aggregating micro relationships and searching among the aggregates for stable macro relationships is useful. This proposition, however, may be flawed and may not be productive in real situations. A macro variable is one that measures an aspect of the overall dynamical system. Macro relationships will most likely be found within the parameters of system-wide properties' time varying probability distributions.
