Epstein Zin preferences and asset pricing

[georam11]

Hello All,

I am a beginner in Dynare. I would like to use Dynare for a basic optimisation problem in asset pricing with epstein zin preferences. I have referred to https://github.com/JohannesPfeifer/DSGE ... 2.mod#L124 while building the codes (with some changes as I would like to get the stock return instead of return to capital). I have referred to Kung and Schmid (2015) for to build this basic model version.

I have not included the Euler equation as Kung and Schmid (2015) does not include the same in the equilibrium conditions. Do you think this is what is causing the problem?

When I run the file to solve the model, i get the following error message. Please could you help to see if there is something wrong in my code?

Your steady state for k should be

Code: Select all

k=((1/beta-(1-delta))/alpha)^(1/(alpha-1))*lab;

Thank you prof Pfeifer.

I am able to solve the model now.
