The Effects of Transfers
The consequences of transfers fall into a few buckets. The two most obvious are the the immediate first-order effects:
- The positive welfare effect from providing assets to the poor
- The negative welfare effect from taking assets from the rich
Then there are the medium-term second-order effects:
- Reduced labor from the disincentive to work
- Improved long-term outcomes from better access to resources
Finally, there are the more controversial long-term effects regarding the effects of transfers on culture and the gene pool.
We will examine each of these in turn.
First Order Effects & Labor Discincentives
The first order effects of transfers are really part of a broader conversation on optimum taxation and are typically weighed under a framework of social welfare maximization. This is also the proper way to weigh the labor disincentivizing effects. See here.
It's uncontroversial that welfare boosts the quality of life of its recipients in the short-run, but its not nearly as obvious that there are long-term effects. For instance, if there were long-term effects, we'd expect the generous welfare states in Europe to lead to more equal pre-tax-and-welfare income. This is not really the case Gini in the bottle. Still, there is some evidence for long-term effects:
- One researcher found that removing a youth from SSI reduces their younger siblings' adult incomes by about $5,000 per year Deshpande.
- A group of researchers looked at when different counties got access to food stamps and the association between that and life outcomes. They found significantly positive effects Bailey.
- The sons of mothers receiving government pensions in the early 1900s had higher adult incomes than the sons of mothers who were rejected Aizer.
- Expanding the EITC causes positive effects on educational outcomes while increasing labor participation Maxfield.
- Access to Medicaid has positive effects on children's eventual incomes Brown and even has positive effects on the children's children East.
- Children raised in families that receive housing vouchers earn more as adults than children from similar families who don't Andersson.
There are two problems with these studies. The first is that they are only quasi-experimental, so while suggestive of causal effects, they're hardly a gold standard.
The second is that we have no way of knowing whether these results are actually positive-sum. For instance, several of the studies find transfers increased educational attainment, but it isn't clear that this is actually a worthwhile goal.
Likewise, it's entirely possible the income effects may come from zero-some vectors rather than genuine increases in human capital. As far as I can tell, no one has seriously examined this hypothesis.
The long-term effects of transfers are mostly speculative.
Most likely, transfers reduce labor force participation. We know they do in the short-run and long-run elasticities are generally larger than short-run elasticities. That being said, some of the above studies find positive long-term effects on incomes, so its at least plausible transfers can boost labor participation.
But all of that is kind of moot since it's not obvious whether marginally more labor participation is good or bad. Arguments that it is good generally spin a narrative that work is "good for the soul" by giving a sense of accomplishment, purpose, responsibility, and an appreciation for the value of labor. Arguments that more labor is bad generally rest on claims that most marginal consumption is zero-sum.
Conservative commentators will sometimes claim that transfers cause cultural and genetic changes by encouraging rent-seeking and allowing poor people to have more children, which presumably reduces the genetic capability of the population to produce. These claims are obvious extremely controversial.
