How so? Did you read PMZ's link. Did he get the math wrong too? Again, if so, how? Last I checked when you avg a group of numbers the low numbers in the range rise to the avg. and the high numbers in the range fall to the average.
Actually, yes, he got the math wrong.
There is no rule in math that says that when new numbers are added, the mean must go up. And, there is no rule in micro-economics that says that the equilibrium price must go up with quantity. And there is no rule in macro-economics that says that the real "price" must go up.
There is no evidence that demonstrates all these new numbers are higher risk. This is the assumption made in the article. The article depends on this "adverse selection" criteria that it never proves. There is just as much reason to consider that the opposite is true. Even if adverse selection were at work specifically in the health insurance market, that doesn't mean it is at work in the aggregate health care markets. The insurance market is the end use point for the majority of the health care market.
One point is that the total cost of health care, including insurance premiums, is primarily a function of the service used, not a function of the service insured for. This is true for insurance premiums as well. Adding covered service to a health plan does not necessitate that the price rise. If pap smears were added as a service to an insurance plan that accepted only men, it wouldn't add a dime. If prostate examinations were added as a service to an insurance plan that accepted only woman, it wouldn't cost a dime. There is no rule that says adding a service increases cost.
Even then, approaching the problem from a "price" perspective is completely useless. To begin with, there is service provided the uninsured. Then there is the simple fact that "price" and "cost" are not the same thing. Nominal and real price are not the same. And, there is the issue that wages are not fixed. They are highly dependent on numerous factors, including the employment to population ratio.
To apply the simple micro economic models, market imperfections have to be ignored. And the fact is that the health care markets, including insurance, includes every imperfection imaginable. And this includes the effects of the general labor market.
In addition to the note above regarding covered but underutilized service, if we are to apply a simple model, it would be this;
1) The aggregate price paid for all healthcare services provided is divided up among the consumers that pay for health care and insurance as well as the tax payer. That aggregate price is simply not assigned to the uninsured though they do receive health services. The poor and disabled are already insured. They are insured under Medicare, Medi-caid, or simply by the cost write offs by health care providers. Regardless, every working person is covering the cost of healthcare, including the uninsured. Those not paying for insurance are essentially off book.
2)The real price of health insurance and care is dependent on simply the nominal price but also upon the wages earned. The difference between an economy where no one purchases a good and one where everyone purchases a good is exactly the price of that good. The only caveat is if the production of that service detracts from the production of some other service or good. For that to occur requires that the employment to population ratio be at itÂ’s highest level. That is no less than 64.4%.
3)Much of the health insurance and care market is a volume, efficiency of scale business where the significant costs are fixed costs. The insurance market is definitively such.
The simple essence of these are that the change in the health care markets will be a shift in supply along with an increase in quantity demanded. And this is just to start.
The point of presenting the available data on group coverage is that it is real data available about the real market.
