# A code to solve for the optimum in the bathtub model This project contains Fortran and AMPL code to solve for the optimum in the Bathtub model. Two types of utility functions are considered: - alpha-beta-gamma tastes, and - smooth utility (logarithmic and exponential) ## Dependencies The Fortran code calls some standard functions and libraries: - DFZERO function - lapack and Blas and relies on - IpOpt (Fortran version) for the optimization process.
