However, in these applied works, not only is the same iso-hiring curve assumed to exist for all sectors, but it is also assumed to be a rectangular hyperbola.
Consider Figure III where both sectors have the same iso-hiring curve [H[prime].sub.1][H[prime].sub.2] - [H[prime].sub.1][H[prime].sub.2] which is a rectangular hyperbola. Now suppose that the vacancy-unemployment ratio in sector 1 is given by point [A.sub.1] and in sector 2 by point [B.sub.2].
IDENTICAL ISO-HIRING FUNCTION RECTANGULAR HYPERBOLA
This law is due to the fact that the element content Y when estimated in relation to 1 gram-atom, in any chemical combination with molecular mass X, may be described by the adduced equations for the positive branches of the rectangular hyperbolas of the type Y = K/X (where Y [less than or equal to] 1, K [less than or equal to] X), arranged in the order of increasing nuclear charge, and having the common virtual axis with their peaks tending to the state Y =1 or K =X as they become further removed from the origin of coordinates, reaching a maximum atomic mass designating the last element.
In this case, if K is the atomic mass, the equation Y = K/X would represent a rectangular hyperbola in the first quadrant (K > 0).
