Notes: Important errors, modified getting clustering because of the county away from birth, are offered into the parentheses

Most of the regressions include dummy details for census season, competition, many years, county out of delivery, and you can cohort of delivery, and you can area for delivery fashion. Study was aggregated to state of beginning ? season out of beginning ? census 12 months phone function in the 1st column, however, at private top toward IV regressions. Comprehend the notes so you can Table step one .

Brand new IV estimates signify new causal outcomes of early teenager relationships and you will dropout reputation on upcoming impoverishment is actually big. The fresh standard prices imply that marrying young advances the chances a good more youthful bride can be inside the poverty later in daily life by the as much as 29 payment facts. Losing out-of senior high school provides a fairly smaller, but nonetheless large, eleven commission part affect upcoming impoverishment. These results are strong concise out-of aggregation, LIML estimate, changes to possess migration, and a running form approach. The person-level OLS rates to possess very early adolescent marriage was small, while aggregated OLS estimates give a quotation that’s of the same magnitude due to the fact IV rates.

To raised appreciate this brand new IV and you may aggregated OLS rates differ plenty in the individual-level OLS quotes, We today explore the latest part out of dimensions mistake. When you look at the census analysis, years in the beginning wedding are computed on advertised time out-of earliest marriage and go out of delivery (week and you may year). Always only 1 individual fulfills from the census form for the entire home. This is likely to exacerbate measurement error due to the fact people doing the newest census might not have exact factual statements about almost every other domestic members’ times off birth and you can first wedding. Inside 1970 and you may 1980, this new census setting shows individuals “render your best guess” when sometimes ones times is “unidentified.” 19

While the tiny fraction off very early teen marriage ceremonies is really so quick, any mismeasurement of go out from delivery otherwise date out of wedding-the two parameters used to build ages in the beginning wedding-does trigger an incredibly higher downwards bias during the the newest OLS estimate of one’s early teenager ount off dimensions mistake, the new wrongly classified teen brides normally outnumber the genuine adolescent brides, causing nice attenuation prejudice.

To better see the frequency away from dimension error during the stated dates, check out the 1975 National Virility Questionnaire (NFS). It was the 5th inside the some surveys used the five years to look at ily believed. The new fascinating feature of your own survey for the 1975 is that the boffins chose to reinterview a designated shot of women on the 1970 survey. This new reinterview take to is sold with dos,355 light feamales in its very first marriage ceremonies who have been constantly partnered, whoever age at the relationships was below twenty five years, and you can whose husbands had been recently partnered only once. Both 1975 and you may 1970 studies ask date out-of beginning and day out-of earliest wedding, that have both categories of answers getting registered regarding 1975 test. Very because of it subset of women, I am able to determine a reduced likely toward misreports of the evaluating the newest exact same woman’s responses more a great five-year big date horizon.

Misreporting generally refuses because a good woman’s stated ount regarding error into the this type of almost every other communities are small compared

Dining table 8 tabulates how frequently brand new solutions throughout the 1975 questionnaire do not match the solutions on 1970 questionnaire. For the entire shot, schedules off birth don’t consent 4% of the time, and you may times from wedding don’t concur twelve% of time. The result is one an excellent female’s age at the marriage mentioned inside the decades does not fall into line to have eleven% of the observations regarding the test. Mismatch prices also are claimed from inside the Table 8 for groupings based into an effective woman’s claimed wedding ages on the 1970 survey. Of these marrying within or below the age of 15 for the the 1970 survey, 8% single men men dating New York regarding delivery times and you can 35% of relationships schedules don’t line-up round the questionnaire years. For it class, 39% of your required matrimony years differ along side studies. The degree of dimension mistake regarding the census has a tendency to be even big while the 1975 NFS tested merely women who got never separated along with ladies answer questions regarding the themselves.
