No impact of technology shock on output

I am new to DSGE and I have formed a code for four sector economy based on RBC model. Here, I am unable to get the impact of e_z (Technology Shock) on output (f), GDP(y), Consumption (c) and Investment (in). Kindly help me out.

Only do the exp()-substitution once the model works.

Thank you professor for your response. So I need to write the equation without exp?

For the beginning, yes.

thank you Professor
