N2 - For any nonzero h ∈ ℤ, we prove that a positive proportion of integral binary cubic forms F do locally everywhere represent h but do not globally represent h; that is, a positive proportion of cubic Thue equations F(x,y) = h fail the integral Hasse principle. Here, we order all classes of such integral binary cubic forms F by their absolute discriminants. We prove the same result for Thue equations G(x,y) = h of any fixed degree n ≥ 3, provided that these integral binary n-ic forms G are ordered by the maximum of the absolute values of their coefficients.
