Villanova Scientists Prove that DTC Spending Does Not Impact Rx Prices

According to Jim Edwards at BrandweekNRX, "The boffins in the business school at Villanova University are touting a formidable study with this headline: DTC advertising has no effect on the price of drugs" (see post).

Here's the elegant proof cited in the report, which you can download here:



"where it q is the quantity sold for brand i in time t (in 000s), it p is the price of brand i at time t (in dollars per unit), the lower case advertising variables represent the flow or current period advertising (in $000’s), the upper case advertising variables represent the current stock of advertising up to time t (in $000’s), it Exper is the number of months that drug i was on the market prior to time t , and it cp is a weighted average of competitors’ prices at time t . We take logs of both price and quantity so that 1 β represents the price..."

And so on. I think you get the drift.
