where M⁸ œ M/)(p,M) is normalized income. From equation (3), it can be seen that in
this model, the utility index is strictly Positive.

Differentiating (2) with resPect to P₃⁸ , the Hicksian demands are

These Marshallian demands have a functional form that is a hybrid of the semilog and
linear demand functions: the Price effects are similar to those of the semilog system
while the income effects are linear. Notably, the income effects "3 in (5) are not
restricted as they are in the semilog demand system, where they must all take on a single
value.
