It most probably has to do with your timing for capital and the two-sector structure. See > [@Timing of capital in two sector economy](https://forum.dynare.org/t/timing-of-capital-in-two-sector-economy/2325): > > Hello all, I am building a two-sectoral model, and I have a question about the timing of sectoral-capital variables: In my model, T and N are sectors, hence kT is capital in sector T and kN is capital in sector N. Then, I assume that the economy’s aggregate capital is simply: k = kT + kN. However, I assume only one law of motion for aggregate capital such that: k = (1-delta)\*k(-1) + i - written in Dynare language. It is clear to me that k is a predetermined variable and should be treated as su… --- _[View the full topic](https://forum.dynare.org/t/blanchard-kahn-conditions-fails-in-a-two-sector-two-types-of-agents-model/11380)._
