What the study found
Linked environmental regulation in Texas performed substantially better than both unlinked regulation and untargeted regulation. The study also found that a large share of this benefit came from a firm-wide moral hazard mechanism, meaning that enforcement at one plant can affect compliance behavior across other plants owned by the same firm.
Why the authors say this matters
The authors say linked regulation can help regulators use scarce enforcement resources more efficiently by directing attention toward bad actors without having to inspect every plant. The study suggests this may be especially useful when compliance costs are correlated across plants within the same firm.
What the researchers tested
The researchers developed an empirical framework for dynamic moral hazard under linked regulation, allowing for large portfolios of plants and interdependent choices within a plant portfolio over time. They used this framework to evaluate a linked regulation scheme in Texas and to test two theoretical mechanisms behind its benefits: a firm-wide moral hazard mechanism and a correlated targeting mechanism.
What worked and what didn't
The linked regulation scheme outperformed both unlinked regulation and untargeted regulation in the Texas evaluation. When the authors tested the two proposed mechanisms, they found that a large share of the value of linked regulation was due to the firm-wide moral hazard mechanism.
What to keep in mind
The abstract does not describe detailed limitations, and the summary is limited to the Texas case studied. The findings are presented as an evaluation of one linked regulation scheme and two mechanisms within the authors' framework.
