1. The problem statement, all variables and given/known data 6.3.b highlighted in attachment. Have solved part a (which gives the approximant used in part b) and problem 3.8 (which gives the original function). 3.8 was definitely solved correctly. Part a could be wrong, but the solution seems OK. a = acreage y = yield from 3.8 - p1,p2,c1,c2 are prices and consumption in periods 1 and 2. 2. Relevant equations a = 0.5+0.5*Ey(f(ay)) where Ey is the expected price in terms of y and f(ay)=p1(s). 3. The attempt at a solution %DEFINE FUNCTION FOR Part b function [fval] = f63b(y) fval = 0.5+0.5*Exp; %5-POINT GAUSSIAN QUADRATURE [y,w] = qnwlogn(20,0,0.01); Exp = w'*p1; fprintf('Exp'); disp(Exp) a = broyden('f63b',s/2); fprintf('a'); disp(a) Gives value for expectation that is accurate, but then the following error: ??? Undefined function or variable 'Exp'. Cannot find solution for a! Should we have 5 nodes or 20? When change to qnwlogn(5,0,0/01) get no value for Exp.
