delim{[}{A_{alpha}/{l_alpha}^T}{]} it is possible to calculate the Standard commodity associated to this technique, denoted by {y_alpha}^*.

If we want to compare technique alpha with another technique, say beta, we must draw on the same graph the relation between the rate of profit and the wage rate associated to technique α expressed in terms of {y_alpha}^', which can be denoted by {omega^alpha}_{{y_alpha}^'} (r), and the relation between the rate of profit and the wage rate associated to technique beta still expressed in terms of {y_alpha}^', which can be denoted by {omega{^beta}}_{{y_alpha}^'} (r).

As we know, {omega{^alpha}}_{{y_alpha}^'} (r) is linear but {omega{^beta}}_{{y_alpha}^'} (r) is not linear, because bundle {y_alpha}^' is not an invariant standard of value with technique beta. Relations {omega{^alpha}}_{{y_alpha}^'} (r) and {omega{^beta}}_{{y_alpha}^'} (r) may thus intersect more than one time, making ambiguous the order of technique with respect to their capital intensities.
