Consider a group of economic agents with strictly bounded rationality and information that evolve their income allocation strategies through selective imitation. Here we show that if income can be calculated by a Cobb-Douglas type production function, it depends on the production coefficients and not on prices whether a strategy is imitated. Further we show that when an agent adopts a new strategy, the effect on its income growth rate is immediately visible to other agents, which allows imitating agents to quickly optimize their strategies when needed.
