By 2003 there were 16 branded products available in the market along with generics for many expired patents, spanning across three main molecules: methylphenidate-HCL (MPH), mixed amphetamine salts (MAS), and dextroamphetamines (DEX).

This strand of the literature focuses on overcoming the data limitations that are often present in standard economic settings, such as the absence of individual level data, unobservable product In this tutorial, we’ll use data from Nevo (2000) to solve the paper’s fake cereal problem. Locations of CSV files that contain the data are in the data module.. We will compare two simple models, the plain (IIA) logit model and the nested logit (GEV) model using the fake cereal dataset of Nevo (2000).

I discuss an alternative, which consists of demand

Although the concept choice models is widely understood and practiced these days, it is often difficult to acquire hands-on knowledge in simulating choice models.While many stat packages provide useful tools to simulate, researchers attempting to test and simulate new choice models with data often encounter problems from as simple as scaling parameter to misspecification.
