We explore whether having dominated options is common by analyzing data on plan designs from the Kaiser Family Foundation Employer Health Benefits Survey for firms that offered employees both a high-deductible (HD) health plan and a lower-deductible (LD) option.
In 65% of firms the high-deductible option would result in lower maximum possible health spending for the employee for the year.
We present evidence that these patterns may arise naturally from employers passing through large average-cost differences between HD and LD plans to their employees.
We discuss the implications of those dynamics for the nature of transfers between employees and the efficiency of health spending.
The booster, with its 42 Raptors, will be the most powerful rocket in history, by far.
It will be capable of launching 300 metric tons (330 tons) to low Earth orbit (LEO), or 550 metric tons (600 tons) in an expendable variant, Musk said.

Space X's billionaire founder and CEO just published the plan, which he unveiled at a conference in Mexico in September 2016, in the journal New Space.
Musk's commentary, titled “Making Humanity a Multi-Planetary Species,” is available for free on New Space's website through July 5.
“In my view, publishing this paper provides not only an opportunity for the spacefaring community to read the Space X vision in print with all the charts in context, but also serves as a valuable archival reference for future studies and planning,” New Space editor-in-chief (and former NASA “Mars czar”) Scott Hubbard wrote in a statement.
