01/07/2019 Theory and Concept on aggregate Impact value . In physical meaning toughness is property of a material to resist impact. Due to movement of vehicle on the road the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregates should therefore have sufficient toughness to resist their disintegration on due to impact. This characteristics is

We develop a theory for aggregate market impact in terms of the competing random walks of net volume and net returns. Under the assumptions that individual impacts are permanent and IID we show that the aggregate impact R for N trades of net signed volume V scales as R ∼ VN−κ. If the distributions of volume ﬂuctuations and return ﬂuctuations are suﬃciently thin tailed, κ = 0, but ...
