How Much Does Health Insurance Cost? Comparison of Premiums in Administrative and Survey Data
Using newly available administrative data from the Internal Revenue Service, this paper studies the distribution of employer-sponsored health insurance premiums. Previous estimates, in contrast, were almost exclusively from household surveys. After correcting for coverage limitations of the IRS data, we find that average premiums for employer-sponsored plans are roughly $1000 higher in IRS records than in the Current Population Survey. The downward bias in the CPS is largely driven by underestimating of premiums among married workers and topcoding of high premiums.
Income and Earnings Mobility in U.S. Tax Data
We use a large panel of federal income tax data to investigate intragenerational income mobility in the United States. We have two primary objectives. First, we explore the determinants of two-year changes in individual labor earnings and family incomes, such as job or industry changes, marriage, divorce, and geographic mobility. Second, we evaluate how federal income taxes stabilize or destabilize post-tax income changes relative to pre-tax changes. We find a relatively high degree of income mobility, with almost half of workers exhibiting earnings increases or decreases of at least 25 ...
Household Incomes in Tax Data : Using Addresses to Move from Tax Unit to Household Income Distributions
Tax return data are increasingly the standard for tracking income statistics in the United States. However, these data have traditionally been limited by their inability to capture non-filers and to identify members of separate tax units living in the same household. We overcome these obstacles and create household records directly in the tax data using mailing address information included on tax forms. We then present the first set of tax-based household income and inequality measures for the entire income distribution. When comparing household income inequality results in the tax data to ...
Whose Child Is This? Shifting of Dependents Among EITC Claimants Within the Same Household
Using a panel of household level tax data, we estimate the degree to which dependents are "reassigned" between tax units within households, and how these reassignments affect combined tax liabilities. Reassigning dependents reduces combined tax liabilities on average, suggesting some household level coordination. Additionally, when EITC benefits expanded in 2009, reassignments increasingly involved adding a third child to tax returns to claim these new benefits. However, the subgroup reassigning towards three child tax units actually increased total household tax liabilities, suggesting that ...
