Evaluating the effectiveness of international agreements is inherently difficult due to the problems of self-selection, spillovers, and aggregate-level data. In this paper, I provide new and arguably more credible estimates on the effects of the Long Range Transboundary Air Pollution (LRTAP) protocols on three different pollutants: SO2, NOx, and VOCs. I address the problem of non-parallel emission trends by constructing “synthetic” controls that mimic the pre-treatment development of each affected country. Using a new dataset covering more regions and a longer period than previously applied, I find that all three protocols induced emissions reductions well beyond a (synthetic) counterfactual development. |
