Using newly-linked administrative and commercial data from Virginia spanning 25 years, we study the consequences of incarceration. While previous research has examined labor market outcomes and recidivism, we focus on two of the primary channels through which low-income households build wealth: asset ownership (homes and cars) and human capital formation. To identify causal effects, we use a matched differencein-differences design. In line with much of the literature on the impact of incarceration in the U.S., we find no evidence of scarring effects on labor market outcomes or changes in recidivism beyond the incapacitation period. However, we find that incarceration leads to a persistent reduction in asset accumulation: seven years after sentencing, homeownership has declined by 1.1 percentage points (12.1%) and car ownership by 2.7 percentage points (18.1%). Incarceration also lowers human capital formation, reducing college enrollment by 1.4 percentage points (15.1%).

In the last decade, the United States has seen a wave of efforts to greatly reduce or eliminate the use of solitary confinement. In the light of growing international recognition that such treatment amounts to torture, these efforts are certainly encouraging and have contributed to a reduction of the number of people held in long-term isolation. But it is worthwhile to examine the extent of these reforms and what solitary confinement now looks like in states that have implemented such changes.

A robust literature exists on the harms of solitary confinement and ideas for reforming or eliminating its use. This paper adds to the literature by evaluating the success of such efforts, several years into this wave, now that there is more data available. It examines two states that have presented themselves as success stories, Massachusetts and Colorado, where the correctional agencies purport to have eliminated long-term solitary confinement. Although its use has been greatly reduced, it persists for some number of incarcerated people—prompting the question of why these agencies are not more forthright about their progress.

This paper uses these two states to illustrate larger trends and concludes by suggesting ways that advocates can ensure that their efforts are maximally successful as the trend of eliminating solitary confinement hopefully continues. It contributes to the scholarship evaluating how our democracy’s branches—judicial, executive, and legislative—can provide meaningful restraints on correctional agencies’ actions in order to protect the people in their custody.
