- "Does content affect price?" It seems the journalist and PG define "price" differently -- is it the price to the consumer or to the publisher? Either way affects profit, so both seem valid to me.
Hence, I feel the journalist has a valid point. Laura Bush will command higher royalties. So, the price to the publisher is increased (via higher royalties/advances), because Laura Bush provides desirable content. The journalist also states that while the price to the consumer is not higher, the publishers' business model is to sell more copies at a lower profit margin per copy, which seems perfectly valid.
- "Better journalism is slightly cheaper." In some cases, yes. In others, no. Arguing over Time vs. The Economist seems to not answer the broader question.
