From the Economist, The economics of thinness,
Myriad studies which find that overweight or obese women are paid less than their thinner peers while there is little difference in wages between obese men and men in the medically defined “normal” range.
... research in America, Britain, Canada and Denmark suggests that overweight women do have lower salaries. The penalty for an obese woman is significant, costing her about 10% of her income.An economist at the BLS offers a partial explanation: “the increasing rarity of thinness has led to its rising premium.”

[those] who view the world in more zero-sum terms tend to support policies that redistribute income from the rich to the poor ... This includes redistributive policies like taxation, universal healthcare, and affirmative action for women and African-Americans. .HT: MarginalRevolution.com..zero-sum thinking is associated with preferences for liberal economic policies in general and with stronger political alignment with the Democratic Party

APNews: A new federal law requiring that sesame be listed as an allergen on food labels is having unintended consequences — increasing the number of products with the ingredient.
Food industry experts said the requirements are so stringent that many manufacturers, especially bakers, find it simpler and less expensive to add sesame to a product — and to label it — than to try to keep it away from other foods or equipment with sesame.
This is analogous to the infamous Cobra Effect, when a bounty on dead Cobra's was set so high that it became profitable to raise the snakes and then kill them for the bounty.

As the FTC and DOJ continue to focus their attention on resource-intensive enforcement of a few high-profile technology and pharmaceutical companies, practitioners see more deals escaping scrutiny.
So basically, if President Biden's regulators are busy elsewhere, they cannot prevent as many mergers.

I just spoke with someone who had all her bridesmaids sized in the store only to go online and buy them from a discount site. I would assume many of the brides are doing this as well.Note that this is not just a problem for the store, but also a problem for the dress manufacturer: if stores cannot prevent free-riding, they will invest less in point-of-sales fitting services, and dress sales will suffer. See our earlier post about golf club manufacturer PING, who faced a similar problem,
The discount retailers were advising consumers to visit a full-service retailer to request a custom-fitting session, and then bring the specifications for custom-made clubs back to the discounter. PING could control this kind of opportunistic behavior only by dropping dealers, a very costly option.PING wanted to set a minimum retail price (called "retail price maintenance") to address the problem. The minimum price meant that discount retailers could not undercut full service retailers. The antitrust laws prevented this until the Supreme Court changed the case law.
For the wedding dresses, the no-photos policy created a problem for Stephanie because she wanted to photograph her bridesmaids in each of the dresses to make sure that they choose the best dresses for the wedding. So she chose to purchase from a large retail chain, like J. Crew, BCBG, Ann Taylor, or Nordstrom’s because they had solved the free riding problem, using exclusives, where only one chain carries the style.
For an economic analysis of resale price maintenance, see the amicii brief of 24 antitrust economists (I am one of the 24.)
UPDATE: Amazon just made free riding a lot easier.
Consider, for example, video tape rental industry. Prior to 1998, distributors sold video tapes to rental outlets, which proceeded to rent them to end consumers. The tapes sold for around $60 apiece, far in excess of marginal cost. The rental stores, naturally enough, economized on their purchase, leading to queues for popular movies.The old contractual form suffered from double marginalization, which resulted in video rental prices that were too high and output that was too low.
The Blockbuster CEO recognized this as a problem and proposed a solution:
In 1998 the industry came up with a new contractual form: studios provided video tapes to rental stores for a price between zero and $8, and then split revenue for rentals, with the store receiving between 40 and 60 percent of rental revenues.Although the stores marginal revenue was cut in half, the marginal cost of a video went down by about 90%. As a result,
.. these contracts increased revenue of both studios and rental outlets by about 7 percent and consumers benefitted substantially. Clearly, the revenue sharing arrangement offered a superior contractual form over the system used prior to 1998.This arrangement is subject of course to verification of the downstream revenue by the upstream distributor. New "smart" cash registers at Blockbuster made this possible:
The interesting thing about this revenue-sharing arrangement is that it was made possible only because of computerized record keeping. The cash registers at Blockbuster were intelligent enough to record each rental title and send in an auditable report to the central offices. This allowed all parties in the transaction to verify that revenues were being shared in the agreed-upon way. The fact that the transaction was computer mediated allowed the firms to contract on aspects of the transaction that were previously unobservable, thereby increasing efficiency.More of Hal Varian's insights about economics (there are some good stories here) can be found in his popular columns. He is most famous to MBA's for saying that "marketing is the new finance," urging the Quants, who used to go into finance, go into marketing instead.

The British government, concerned about the number of venomous cobras in Delhi, offered a bounty for every dead cobra. Initially, this was a successful strategy; large numbers of snakes were killed for the reward. Eventually, however, enterprising people began to breed cobras for the income. When the government became aware of this, the reward program was scrapped. When cobra breeders set their now-worthless snakes free, the wild cobra population further increased.
- In 2005 the UN Intergovernmental Panel on Climate Change began an incentive scheme to cut down on greenhouse gases. Companies disposing of polluting gases were rewarded with carbon credits which could eventually get converted into cash. The program set prices according to how serious the damage the pollutant could do to the environment was and attributed one of the highest bounties for destroying HFC-23, a byproduct of a common coolant,HCFC-22. As a result, companies began to produce more of this coolant in order to destroy more of the byproduct waste gas, and collect millions of dollars in credits.
- The United States Endangered Species Act of 1973 imposes development restrictions on landowners who find endangered species on their property.a While this policy has some positive effects for wildlife, it also encourages preemptive habitat destruction (draining swamps or cutting down trees that might host valuable species) by landowners who fear losing the lucrative development-friendliness of their land because of the presence of an endangered species. In some cases, endangered species may even be deliberately killed to avoid discovery. This same perverse incentive has also been observed in other countries, including Canada and various European countries.
- Floods: because floods hit all the homeowners in an area at the same time, so insurers cannot diversify the risk (called "correlated risk") so insurance companies become more risk averse, so there is less of a gain from insurance
- Earthquakes: adverse selection costs are high (only the homeowner knows if they are close to an active fault) and how likely it is that their house would withstand an earthquake; and
- Bedbugs: moral hazard costs are high (once consumers buy bedbug insurance, they engage in riskier activities, like picking furniture off the street).
