Deterministic model

Hi, Professor Pfeifer

 I build a small open economy model to study foreign reserve accumulation. I want to study the transition paths of some macro variables by changing the exogenous variable,e.g financial tightness. I run into a problem after running my mod file,  I find the transition dynamics of endogenous variables are constant. Why does this situation happen?  I upload two of my mod files in the attachment.

It seems no solution to your model was found. Please check the output in the command window.
The most recent unstable version finds a solution for the financial_friction.mod where d oscillates using homotopy. These oscillations suggests a timing problem.
