What Do We Do in This Chapter? We conduct comparative statics analysis of ordinary demand functions the study of how ordinary demands*(p,,P2,y) and x2*(p1,p2,y) change as prices1,P2 and income y change. Theoretically, nothing new
1.Integrability Demand function x(p,w)(.d.) is HDO, satisfied Walras Law and have a substitution matrix S(p,w) is s.n.s.d. for any (p,w), if it's deduced by rational preference. And if we observed an x(p,w) satisfied such conditions, can we find a preference to rationalization(p,w)? That the integrability problem
