Having a criminal parent jailed reduces children’s likelihood of incarceration by 4.9pp.
This finding is intuitive to me, “…Every year, millions of Americans experience the incarceration of a family member. Using 30 years of administrative data from Ohio and exploiting differing incarceration propensities of randomly assigned judges, this paper provides the first quasi-experimental estimates of the effects of parental and sibling incarceration in the US. Parental incarceration has beneficial effects on some important outcomes for children, reducing their likelihood of incarceration by 4.9 percentage points and improving their adult neighborhood quality….parental incarceration decreases the likelihood that a child is charged with a crime, convicted, or incarcerated before the age of 25 by 6.6, 5.5, and 4.9 percentage points respectively.2,3 These effects are concentrated among black children…While estimates on academic performance and teen parenthood are imprecise, we reject large positive or negative effects. Sibling incarceration leads to similar reductions in criminal activity….”
Back to this paper what they try to do, “….We make three main contributions relative to these papers. First, although we study only one state, we emphasize the policy relevance of the US context: there are currently over 2 million prisoners in the US, making up one- fifth of all prisoners in the world, as opposed to approximately 5,400 in Sweden, 3,700 in Norway, 3,100 in Finland, and 121,000 in Colombia… Second, motivated by the prevalence of sibling incarceration 34% of US inmates have a brother who has been incarcerated, as opposed to 19% with an ever-incarcerated father….we provide some of the first estimates of the spillovers of sibling incarceration. Third, the breadth and depth of our data permit us to investigate differences in effects among different interesting subsamples (e.g. socioeconomic status, racial groups) and provide novel tests of the mechanisms at work…. The net result is that incarceration reduces the total criminal exposure for family members over the following 30 quarters by approximately 0.6 crimes, relative to a sample mean of 3.94.2
Core results, “….Tens of millions of Americans have been incarcerated, and a substantial literature has at tempted to understand both the direct and spillover effects of incarceration. In this paper, we provide the first causal estimates of the effects of parental and sibling incarceration in the United States. In contrast to existing correlational evidence,we find that parental incarceration decreases children’s future criminal involvement and improves child long-term socioeconomic status. There are multiple mechanisms that may mediate this effect, including:(1) lower rates of criminal activity by the defendant and the non-incarcerated parent; (2) among male defendants, a greater dedication to existing family; (3) deterrence; and (4) removal of an unstable influence or shifting the child to a more stable care-giving environment.Even if there are notable anecdotes of when parental incarceration has harmed children, there appear to be other, potentially less salient cases in which the effects are positive. These positive cases counterbalance the negative ones to produce economic benefits. We find that sibling incarceration also results in reductions in criminal activity, consistent with the importance of peer effects in the formation of youth criminal tendencies. The timing of the sibling effects indicates sibling incarceration has a direct, short-term influence on criminality, rather than affecting long-term behavior. The relatively positive family spillovers from incarceration have a number of implications for policy. The costs and benefits from the spillovers of incarceration matter for determining optimal sentencing and incarceration policy… and our findings demonstrate a previously unknown benefit of incarceration. We conduct a partial cost benefit analysis and conclude that while the marginal child benefits from parental incarceration, the high costs of incarceration still outweigh the benefits. More broadly, the positive effects of family incarceration we find highlight the challenging environment faced by children with family members on the margin of incarceration, and demonstrate the scope for policy to affect their long-run economic outcomes. However, given the costliness of incarceration, future work should study other interventions that may aid this population..”

Note this finding mirrors a 2018 study we looked at (attached) that found that in terms of crime there are significant spillover (in terms of propensity to be arrested) effects from older to younger siblings (effect is gendered, impacting males)
