A modelling strategy that accounts for measurement outside the laboratory, where one cannot base measurements on a single simple law, will have to drop the requirement that the model is a homomorphic mapping of the empirical relational structure. The model used for measurement will be a...

Mathematical models are instruments of investigation, epistemological equivalent to the microscope and the telescope. In comparing the epistemological difference between models and experiments, Morgan (2005) argues that experiments offer greater epistemic power than models as a means to...

The Representational Theory of Measurement conceives measurement as establishing homomorphisms from empirical relational structures into numerical relation structures, called models. Models function as measuring instruments by transferring observations of an economic system into quantitative...
