The methodological discussion on the calibration of aggregate marketing response models has shifted away from how to obtain usable input for optimization to how to avoid biases in statistical estimation. The goal of this article is to remind researchers that such calibration is performed either...

Estimating structural models is often viewed as computationally difficult, an impression partly due to a focus on the nested fixed-point (NFXP) approach. We propose a new constrained optimization approach for structural estimation. We show that our approach and the NFXP algorithm solve the same...
