The second chapter, The Effects of Conservation Reserve Program Participation on Later Land Use, studies another public goods issue: conservation. The Conservation Reserve Program (CRP) pays farmers to retire farmland. We use a treatment effect framework to find that ex-CRP land is 21-28% more likely to be farmed than comparable non-CRP land. This implies that the CRP improves low-quality land, making it more attractive to farm. This could demonstrate inefficiency, since farmers gain private benefit from a program meant to provide a public good. On the other hand, farmed ex-CRP land is more likely to adopt conservation practices, although this may not be caused by CRP participation.
