Abstract
To the surprise of many, pharmaceutical firms belong to the biggest spenders on marketing. The marketing spend-to-sales ratio may be as high as 30 %. Expenditures in the USA alone were $10.9 billion in 2009. Hence, there is a strong interest in understanding how effectively this industry spends its marketing money.
The objective of this chapter is to review and synthesize the literature on marketing spending in the pharmaceutical industry. It reviews recent trends in pharmaceutical marketing. It looks at how marketing managers in the pharmaceutical industry actually arrive at spending decisions. The author further discusses models that describe how pharmaceutical demand responds to marketing expenditures. He summarizes findings on the responsiveness and profitability (ROI) of various spending categories.
Another focus of the chapter is on normative applications of marketing spending models. Normative models help finding the right budget across spending categories, customer groups, and products. The discussion covers static and dynamic optimization approaches. The author identifies fields of promising future research from this synthesis of the extant literature.

Notes
- 1.
Product management does not only refer to phase III studies that are required to obtain drug approval but also to phase IV studies. These studies are carried out after launch and may include comparative studies to show the superiority of the drug over competitive drugs.

I want to emphasize that I use the term ROI from a marginal analysis perspective. Here, the objective is to find the profit maximizing spending level. The ROI measures the incremental profit gain from an incremental increase in spending level divided by that increase in spending. Practitioners sometimes refer to the ratio of total profit gain and total spending level. By definition, this ratio is maximized if incremental ROI is zero.
