“…where (u, pu q ) corresponds to a fixed point (Y,K), and r is an adjustment cost. In our simulation, we use (p,q,r,u) = (0.3,0.2,1.0,3.0) [22]. To evaluate the system behavior under an income bias, weak signal, and noise, we consider b as the bias term ofẎ , a weak sinusoidal signal I ext (t) = Asin2πf S t, and a Gaussian white noise Dξ(t) (< ξ(t) >= 0,< ξ(t),ξ(t ′ ) >= δ tt ′ , < • > indicates average in t) for Eq.…”
