Hello,

I successfully ran a model with 1 agent and 2 goods which is perfectly symmetric in the goods dimension. The IRFs look great and I think it’s good.

I go from there to a 2 agent, 2 goods economy which is perfectly symmetric in both the goods and the agents. This is just a minor extension of the previous model, I just add the following:

- one intra-temporal Euler equation
- one inter-temporal Euler equation
- one budget constraint
- 1 aggregation equation across the consumption of the two individuals

However, when I run it, it runs into a rank problem:

There are 4 eigenvalue(s) larger than 1 in modulus

for 5 forward-looking variable(s)The rank condition ISN’T verified!

Note I am not using capital so I don’t think it has anything to do with timing. My only thought was the symmetry might be the problem but I deviate from the symmetric case and still get the error.

Any thoughts? For details on the model, see the attached file.

Thank you!
