The structure of beta pricing models 31 based on the 'duality theorem of linear algebra'. 33). 34b) do not capture more than an intuition on the structure of expected returns. As such, this intuition is valuable, but to constitute a theory it needs more formal justification: First, it must be shown rigorously that nonarbitrage conditions can be applied in approximation. 16 Second, it must be demonstrated that the inaccuracy in the APT pricing equation is negligible. Some proofs ofthe APT assume a sequence of capital markets (economies) with an increasing number of risky assets.
