Product Di ﬀerentiation (Helpman and Krugman 1985) The CES utility function has proved very useful in models of product diﬀerentiation. The typical form of modeling prefer-ences is to assume an upper-tiered utility function u(x0,V)=U (x0,V(x1,,xn)) (5.1) where x0 is consumption of some homogeneous numeraire good,
