Given by the second-order conditions of the federal optimization problem A < 0. The sign of
A31 is strictly positive since tjkji > 0 and by assumption (A) tik'i + ki > 0. Helpful in signing
A11 and A21 we rewrite both determinants as:

A11 = β(tik'i + ki) + α      and      A21 = β(tjkji) - α,                 (26)
