Efficient pollution regulation equalizes marginal abatement costs across sources. We study a new flaring regulation in North Dakota and document its efficiency. The regulation reduced flaring 4 to 17 percentage points, accounting for most of the observed flaring reductions at new wells in the...

Efficient pollution regulation equalizes marginal abatement costs across sources. Here we study a new flaring regulation in North Dakota's oil and gas industry and document its efficiency. Exploiting detailed well-level data, we find that the regulation reduced flaring 4 to 7 percentage points...
