Commensurability (economics)

Commensurability in economics arises whenever there is a common measure through which the value of two entities can be compared.

Commensurability has two versions:

While weak commensurability is a form of strong comparability, it is distinct from weak comparability, where the fact that a comparison is valid in one context does not imply that it is so in all contexts. Also issues of comparability are different from indeterminacy: it may not be possible in certain circumstances to make a measurement, even though if such data was available it would be valid to compare measurements.

Commensurability is a key factor in the socialist calculation debate.
