Let r(x,z) be a function that, along with its derivatives, can be consistently estimated nonparametrically. This paper discusses identification and consistent estimation of the unknown functions H, M, G and F, where r(x, z) = H[M (x, z)] and M(x,z) = G(x) + F(z). An estimation algorithm is...

Ergodicity for a nonlinear age-dependent population model with diffusion and T-periodic vital rates is investigated. The existence of at most one non trivial T-periodic and nonnegative separable solution is proved.

The authors analyze the consequences of imperfect output markets for the land-use decisions of semi-subsistence farmers in an agricultural frontier of southern Mexico. The approach is motivated by previous applications of the agriculture household model establishing that the farm...
