We consider an infinite-horizon multi-product dynamic pricing problem with reference effects in a monopolistic setting, where the reference price is an exponentially weighted average of historical prices. In each period, the demand follows the multinomial logit (MNL) model, where the utility...

This paper incorporates heterogeneous threshold effects into the classical multinomial logit (MNL) model, and studies the associated operations problems such as estimation and assortment optimization. The derived model is referred to as the threshold multinomial logit (TMNL) model and...

We study assortment optimization problems under a natural variant of the multinomial logit model where the customers are willing to focus only on a certain number of products that provide the largest utilities. In particular, each customer has a rank cutoff, characterizing the number of products...

Motivated by direct interactions with practitioners and real-world data, we study a monopoly firm selling multiple substitute products to customers characterized by their different social network degrees. Under the multinomial logit model framework, we assume that the utility a customer with a...

We study assortment optimization problems under multinomial logit choice model with two tree structured consideration set models, i.e., the subtree model and the induced paths model. In each model, there are multiple customer types and each customer type has a different consideration set. A...

Interest increased after the last global financial crisis in 2007, as the crisis revealed the challenges facing central banks in dealing with the financial crises arising from the banking sector, and thus exposing the financial positions of the banking sector to high risks that caused the...

This paper characterizes the logit model with menu dependent variance. The characterization follows from two conditions: independent log-odds and log-odds monotonicity. Independent log-odds says the change to log-odds across different menus is independent of the alternatives used to compare...
