Hence, the models are presumed to "trace more clearly the shocks' transmission to the economy."
A fixed-price value measure is used to measure changes in quality and quantity. True to its name, prices are kept fixed for a minimum of two measuring situations. For this reason, it is possible to define the changes in quality and quantity of a most varied and wide range of commodities, keeping apart the changes in income distribution.
