However, a few things you need to be aware
of is that the CPI might not accurately
match the
general inflation rate; so the principal balance on TIPS may not keep
pace with the actual rate
of inflation.
As shown in Figure 3, for more than two decades Medicaid spending in New York and nationwide rose at a
pace well above the
general cost indicator for state and local governments; the near doubling
of the price index between 1991 and 2011 was more than
matched by the greater than quadrupling
of national Medicaid costs and an approximately 350 percent increase in New York's Medicaid expenses.7 (The more rapid growth in other states likely reflected their expansion
of eligibility, which New York had already implemented.)
