Figure shows the combined production function of Angela and Bruno. If the government introduces a new social welfare program to cater to the poor of the society, wherein the reservation wage increases from 2 bushels of wheat to 6 bushels of wheat how would you model the situation? Draw a new diagram to show the impact of this welfare program and comment on who do you think would benefit from this intervention? Additionally, does the outcome of this intervention results in an allocation which is a pareto efficient one? Explain your reasoning.
