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...

We provide a revealed preference analysis of the transferable utility hypothesis, which is widely used in economic models. First, we establish revealed preference conditions that must be satisfied for observed group behavior to be consistent with Pareto efficiency under transferable utility....

In this contribution we propose a dynamic tracking error problem and we consider the problem of monitoring at discrete point the shortfall of the portfolio below a set of given reference levels of wealth. We formulate and solve the resulting dynamic optimization problem using stochastic...
