Anna and Bess are assigned to write a joint paper within a 24-hour period about the Pareto optimal provision of public goods. Let A denote the number of hours that Anna contributes to the project and B the number of hours that Bess contributes. The numeric grade that Anna and Bess earn is a function, 23 In(A + B), of the total number of hours that they contribute to the project. If Anna contributes tA, then she has (24 - A) hours in the day for leisure. Anna's utility function is UA = 23 In(A + B) + In(24 - A); and Bess' utility function is UB = 23 In(A + B) + In(24 - B). If they choose the hours to contribute simultaneously and independently, what is the Nash equilibrium number of hours that each will provide? What is the number of hours each should contribute to the project that maximizes the sum of their utilities?

Using the appropriate diagram(s), explain briefly why the third general equilibrium efficiency condition (i.e. MRSxy = MRPTxy, where x and y are any two products), that connects consumption and production, must hold.
Assume your apartment complex decides to build new open access common area for its residents. Each individual has value for using the common area represented by the following value function: V= 40-0.5Q where Q represents the number of individuals using the common area.

why is the market for recycled aluminium good and the market for plastic bad in the US? Depict this with a firm input choice model. I understand that recycled plastic decreases in qualiy everytime it is recycled while aluminium does not and can be recylced without the decrease in quality, but I dont know how to depict this graphically
Studying has both costs and benefits. If you continue tostudy (e.g., for a test) for as long as the marginal benefitsof studying are greater than the marginal costs, and youstop studying when the two are equal, will your actionbe consistent with having maximized the net benefits ofstudying? Explain your answer.
