The second disparity he is talking about is the lack of declination in out-of-wedlock births in the 80s when AFDC benefits decreased. To quote Tanner,
However, concentrating on AFDC ignores the total value of welfare benefits, which include food stamps, Medicaid, public housing subsidies, and other benefits. As a 1995 Cato Institute study showed, the value of a full package of welfare benefits for a mother and two children ranged from a high of more than $36,000 in Hawaii to low of $11,500 in Mississippi, more than sufficient enough to support to provide an incentive for out-of-wedlock childbearing.
The last gripe which Moffit has the disparity in magnitude. If we look at the 14 biggest studies as detailed in Tanner’s book The End of Welfare: Fighting Poverty in the Civil Society. There is no real discrepancy. There are also some studies which look at family caps and find no correlation. The problem with these studies is that you have to look at the full welfare package of the state and the data there is also quite mixed. And the final study that illustrates my point on the subject, is one conducted by C.R. Winegarden using a brand new regression model which finds that the AFDC alone is responsible for half of the out-of-wedlock birth rate. And as I already mentioned the effect of other programs, this number should be far higher.
As far as the contrary evidence goes in regards to the marriage penalty, Moffit as also spoken there.
Robert Moffitt reviewed the findings of 68 studies on the effect of welfare on marriage and fertility. He concluded that, although there is a consensus that the AFDC program had a negative effect on marriage, there was “considerable uncertainty surrounding this consensus because a significant minority of the studies finds no effect at all, because the magnitudes of the estimated effects vary widely, and because there are puzzling and unexplained differences across the studies by race and methodological approach.
I already touched upon the race issue, but I think the most pressing thing to note is that we are just looking at one program. And the fact is that many programs today reach couples who are ready to marry. In fact, those programs have harsher penalties then the AFDC did. And, of course none of these studies account for the “group effect”. By welfare normalizing bad behavior it becomes a social norm which further exacerbates the out-of-wedlock births. There is also an article I found which supposedly debunks the myth. http://www.huppi.com/kangaroo/L-welfaremarriages.htm
I am going to quickly run through the flaws and provide some counterpoints.
Mississippi has the second highest rate of children born out of wedlock in the country. It also has the lowest welfare and food stamp benefits for AFDC mothers in the country. This correlation generally holds across the nation as well -- states with higher-than-average AFDC benefits tend to have lower-than-average nonmarital birthrates.
This just further proves the point that the AFDC is not the only incentive structure which causes out-of-wedlock births. I already mentioned the Cato Institute study which goes over the effects of the other programs. A lot of the studies I cite mention the AFDC, but it's important to note that most of them refer to aggregate benefits and also discuss other programs like SNAP.
Harvard economists David Ellwood and Mary Jo Bane studied two groups of unmarried women: the first was eligible for benefits if they had children out of wedlock; the second was not. Even by limiting their comparison to states with high welfare benefits, they were unable to find a significant difference in either groups' rate of nonmarital child births.
I found this to be slightly intellectually dishonest as the study just analyzed AFDC benefits. This just illustrates the point further. Michael Tanner actually discusses this study in both his books. In his most recent book The Poverty of Welfare he says this in regards to the study,
It should be acknowledged that the connection is not perfect. For example, Louisiana and Mississippi had approximately the same rate of out-of-wedlock births as did California but had much lower Aid to Families with Dependent Children benefits. 30 That would appear to contradict the argument that high welfare benefits lead to more out-of-wedlock births. But the actual rate of AFDC payments is of far less importance than the value of the entire welfare package within the context of the local economy. 31 In that context, the welfare packages being compared were essentially equal. It is therefore not surprising that they are correlated with similar rates of out-of-wedlock births.
The article then cites this really old study which has very little relevance in the context of a modern debate.
Researchers William Darity and Samuel Myers studied the relationship between female-headed households and the size of welfare benefits in specific geographical areas between 1955 and 1972. They found that the higher the welfare benefits, the lower the rate of female-headed households.(5)
1.Most of the years analyzed were pre-War on Poverty so it does not accurately represent welfare policies today.
2. Over ¾’s of the empirical work finds that welfare does significantly increase out-of-wedlock births:Ron Haskins, "Does Welfare Encourage Illegitimacy? The Case Just Closed. The Answer is Yes," American Enterprise Institute, January 1996.
3. And as for welfare's influence in encouraging mothers to divorce, the General Accounting Office released a report in 1987 that summarized more than one hundred studies of welfare since 1975. It found that "research does not support the view that welfare encourages two-parent family breakup." (6)
Now, Huppi cites a meta analysis regarding welfare and divorce published in ‘87.
And as for welfare's influence in encouraging mothers to divorce, the General Accounting Office released a report in 1987 that summarized more than one hundred studies of welfare since 1975. It found that "research does not support the view that welfare encourages two-parent family breakup." (6)
More recent meta-analyses have found contrary results so newer evidence has rebutted this claim.

The rest of what is stated in the article is addressed higher up in this post.
The last point I would note is that this trait in welfare is not only specific to the United States. To quote Tanner,
The same results can be seen in studies of welfare systems in other countries. For example, a recent study on the impact of Canada’s social welfare system on family structure concluded, “providing additional benefits to single parents encourages birth of children to unwed women”. Studies of Britain have found similar results. Likewise, an Australian study indicated that an increase in out-of-wedlock births as a result of their country's welfare benefits.
Welfare also had effects on abandonment, divorce, and remarriage after divorce.

Tanner sums up the problem quite well,
Of course women do not get pregnant just to get welfare benefits. It is also true that a wide array of other social factors has contributed to the growth in out-of-wedlock births. But, by removing the economic consequences of a out-of-wedlock birth, welfare has removed a major incentive to avoid such pregnancies. A teenager looking around at her friends and neighbors is liable to see several who have given birth out of wedlock. When she sees that they have suffered few visible immediate consequences (the very real consequences of such behavior are often not immediately apparent), she is less inclined to modify her own behavior to prevent pregnancy.Proof of this can be found in a study by Professor Ellen Freeman of the University of Pennsylvania, who surveyed black, never-pregnant females age 17 or younger. Only 40% of those surveyed said that they thought becoming pregnant in the next year “would make their situation worse.”(10) Likewise, a study by Professor Laurie Schwab Zabin for the Journal of Research on Adolescence found that: “in a sample of inner-city black teens presenting for pregnancy tests, we reported that more than 31 percent of those who elected to carry their pregnancy to term told us, before their pregnancy was diagnosed, that they believed a baby would present a problem…”(11) In other words, 69 percent either did not believe having a baby out-of-wedlock would present a problem or were unsure.
So, the idea as later purported in this response, that welfare is not one of the causes of rising single motherhood rates, is simply not true.
Am I just using old studies and focusing on the AFDC?
The first point of import is that I only use old studies as most of the empirical work is quite old. That being said, there are still some new studies which corroborate my arguments. But the argument itself is weak as you have to attack methodology not age.

In regards to the point regarding the AFDC, I have briefly touched upon above but I will continue down here. As illustrated by a comparison between California and Mississippi, AFDC benefits are only a part of general welfare benefits. Despite the comparative lack of benefits in Mississippi the other means-tested benefits also had major deleterious effects. Most of the studies which I cite look at benefits as a whole.
