We provide a rationale for evolutionary model building. The basic idea is that to enhance user acceptance it is important that one begins with a relatively simple model. Simplicity is desired so that managers understand models. As a manager uses the model and builds up experience with this...

One of the mysteries of store-level scanner data modeling is the lack of a dip in sales in the week(s) following a promotion. Researchers expect to find a postpromotion dip because analyses of household scanner panel data indicate that consumers tend to accelerate their purchases in response to...

Several researchers have decomposed sales promotion elasticities. A key result is that the majority of the sales promotion elasticity, about 74 percent on average, is purportedly due to secondary demand effects (brand switching) and the remainder is due to primary demand effects (timing...

Notwithstanding the fact that advertising is one of the most used marketing tools, little is known about what is driving (i) the timing and (ii) the magnitude of advertising actions. Building on normative theory, the authors develop a parsimonious model that captures this dual investment...
