Attached is a very simple mod file in Dynare. and we can calculate the steady state value of capital as
K=((1/beta-(1-delta))/alpha)^(1/(alpha-1));
Then compare this solution with the one dynare gives out, please notice that dynare gives out log(K) since I use a log-linearized version in dynare
It looks the solution from dynare is as big as 4 times of the right solution, or I made a mistake in the mod file.
