Since X\p) is continuous, \i^ = dfi/dpj is also continuous. (See Bonnesen and Fenchel [1], p. ,n, for all p e n . (16) 36 Preference and demand We shall now show that the value of \x at p = p° is m°; that is, that m° = fi(p°). (17) In fact, we have [by definition of x° and of /i(-), with fi(p°) = jd(p°; p°, m 0 )] Suppose m° > /i(p°); then there would exist a vector x1 such that x 1 eD, m° = p°x° > p°x\ x 1 > x°.

The following two lemmas will show that the relation thus defined is in fact an ordering and is independent of the choice of the base price vector p*. The use of the term "income compensation" function in the sense of (3) above is justified by Lemma 8. Lemma 2. Let {p\m'\ {p\m")e£l.

The assertion of the Lemma is implied by the uniqueness of the solution /x(p;p*,m*) of the system (20).
