In the single factor case, given that R i = E(R i ) + i F

Question:

In the single factor case, given that Ri = E(Ri ) + βi F + ϵi , the APT model specified as E(Ri ) = γ0 + γiβ is called the exact APT model by Huberman and Wang (2017). Huberman (1982) considers the representation E(Ri ) = γ0+

γ1βi + α, which Huberman and Wang refer to as an approximate APT model.

Here it is assumed that ∑ni=1 αi = 0 and∑ni=1 αiβi = 0. How can αis be interpreted in economic terms?
