Consumption goods cost 1 EUR and there is no inflation. a What is the present value of her endowment? What is the future value of her endowment? b Suppose she has a utility function given by $U = c_1c_2$ where $c_1$ indicates present consumption whereas $c_2$ stands for future consumption. Find out the optimal intertemporal consumption choice.
