Simultaneity

I have the following equations: q^d=a_0+a_1p_i+u_i and q^s=b_0+b_1p_i+v_i and I know that q^d=q^s=q_i
Additionally I know about E(u_i) = E(v_i)=0 and Cov(u_i,v_i)=0.
I need to find out if the OLS estimate of the intercept is consistent for b_0? And if not, what the bias is. Could someone help me out, any help would be appreciated.
