Eldin is a house painter. he can paint three houses per week. he is considering hiring his friend murphy. together, eldin and murphy can paint five houses per week. what is murphy's marginal product?
Marginal product is the resulting output from one additional unit of a factor of production. Murphy is the one additional unit, and by producing 5 painted houses per week vs 3 painted houses without him, his marginal product is two houses.
