Adding delinquency on Working Capital


#1

Hello everybody,
I changed the working capital model in McCandless (2008) in order that default in loans may occur.

I’m having some trouble with some nominal variables, as follows:
risky_loan_1_7.mod (1.9 KB)

THEORETICAL MOMENTS
VARIABLE MEAN STD. DEV. VARIANCE
y 0.0000 0.0197 0.0004
c 0.0000 0.0214 0.0005
inv 0.0000 0.0491 0.0024
l 0.0000 0.0123 0.0002
w 0.0000 0.0213 0.0005
r 0.0000 0.0138 0.0002
k 0.0000 0.0222 0.0005
p NaN NaN NaN
rn 0.0000 0.0023 0.0000
rf 0.0000 0.0101 0.0001
m NaN NaN NaN
n NaN NaN NaN
z 0.0000 0.0074 0.0001
g 0.0000 0.0023 0.0000
eta 0.0000 0.0100 0.0001

Thank you so much

Hi, you have unit roots in this model. The unconditional moments which are not defined (because of the unit roots) are replaced by NaN in the table. So the output is not wrong.

Stéphane.

Hello,

I’m habing some trouble to get a stable solution for the modelin level. Do you have any guess?

You must not put
steady
before your
initval-block

Hello professor,
I changed it. It’s still not finding a steady state.
Thanks for your help

Investigate the equations with the biggest residuals. From your other posts, I infer you already solved the problem.

Yes, professor Pfeifer, the models are improving. Thanks for your help!
