A partially linear approach to modelling the dynamics of spot and futures prices [PDF]
, 2008 In this paper we consider the dynamics of spot and futures prices in the presence of arbitrage. We propose a partially linear error correction model where the adjustment coefficient is allowed to depend non-linearly on the lagged price difference.
