  Resultants, Jacobians and residues are basic invariants of multivariate
polynomial systems. We examine their interrelations in the context of toric
geometry. The global residue in the torus, studied by Khovanskii, is the sum
over local Grothendieck residues at the zeros of $n$ Laurent polynomials in $n$
variables. Cox introduced the related notion of the toric residue relative to
$n+1$ divisors on an $n$-dimensional toric variety. We establish denominator
formulas in terms of sparse resultants for both the toric residue and the
global residue in the torus. A byproduct is a determinantal formula for
resultants based on Jacobians.
