I thought about this a little.  My conclusion was that it is easier to
get a balanced solution if you use the value function
  T_weight*(max_T - T)^2 + P_weight*(max_P - P)^2

T = trade
P = production
max_[TP] is maximal attainable [T/P] in the city (possibly given a
constraint on minimal food).
 
Best,
G.
