Question E [24'] points} lEonsider the following economy. Time is discrete and runs forever, t = ,1,2,... The emnomy is populated by two types of agents [a measure one of each}: farmers and workers. Earmess own a piece of land that pays a stochastic income 1;. every period. We assume that y: is i_i_d_ across Earmers and time, and that y, m NEE-ca}. Farmers use all their time working their land. Their preferences are given by m} = J'EPlT'Tcl [21) Iior some 1' :n- D. For simplicity, we assume that consumption of farmers can be negative, that is c E R. Moreover, farmers can save {or borrow if negative} in a non-state contingent and non-defaultahle asset c, which has a rate of return 1'. Farmers [ace the thllowing \"No-Fonsi\" condition on assets } a [22) Moreover, farmers can produce and hold capital, k, which is rented to the representative rm in competitive markets [1 unit of nal consumption good produces 1 unit of capital}. Let 1"\" be the rental rate of capital and .5 the depreciation rate. Unlike Earmers, workers don't own land, and they use their available time to work in the representative firm. Assume each worker is endowed with one unit of time. They cannot trade the asset a, but they can produce and hold capital, it [with the same tedinology as farmers]. Their per-period utility is given by u[c], with tr'l[c}| :3- D, tn"{c] a: ll, limu u'{c] = cc, limhm u't'c} = D.
