Hi! I was computing the transition path in the perfect foresight Solow growth model from a given initial capital stock, and keep getting “LoadError: InexactError: Int64(NaN)” when I tried to run the .mod file in Julia. I can’t figure out what went wrong given that the code is so simple (please see below). Can someone help me out here? Many many thanks!

var k;

parameters alpha, delta, s;

alpha = 1/3;

delta = 0.05;

s = 0.1;

model;

k = (1-s)*k(-1)^alpha + (1-delta)*k(-1);

end;

steady_state_model;

k = (delta/(1-s))^(1/(alpha-1));

end;

histval;

k(0) = 1.0;

end;
