I am working on a model and have calculated steady-state values using a steady-state file. Everything seems to be okay. However, an SS value is technically zero but not reported as zero (variable N = 3.85186e-34). I should add that this happens when I include the welfare analysis and its relevant equations in the files; when they are not included, I get the value of N exactly equal to zero. Is this signaling a problem, or should I just ignore it? Is there any way to change the precision in Dynare?
