Livestock grazing on public lands continues to be a source of intense conflict and debate. We analyze this problem using a dynamic game. Low grazing fees let ranchers capture more rent from grazing. This increases the incentive to comply with federally mandated regulations. Optimal grazing contracts therefore include grazing fees that are lower than competitive private rates. The optimal policy also includes random monitoring to prevent strategic learning by cheating ranchers and avoid wasteful efforts to disguise noncompliant behavior. Finally, an optimal policy includes a penalty for cheating beyond terminating the lease. This penalty must be large enough that the rancher who would profit the most from cheating experiences a negative expected net return.

We measure the extent to which curbside access affects quantity recycled. We use novel data to distinguish between new recycling and material diverted from other recycling modes. We find that the marginal impact of expanding curbside programs on total recycled quantities is small, in part because curbside programs significantly cannibalize returns from drop-off recycling centers. Failure to account for cannibalization from other modes may substantially over-estimate the benefits of curbside programs. We conclude with simple cost effectiveness comparisons. Results suggest that incremental expansion of curbside access may not be cost-effective.

A "third wave" of environmental policy has recently emerged that emphasizes information provision as an integral part of the risk mitigation strategy. While theory suggests that information programs may correct market failures and improve welfare, the empirical effectiveness of these programs remains largely undetermined. We show that mandatory information disclosure programs in the electricity industry achieve stated policy goals. We find that the average proportion of fossil fuels decreases and the average proportion of clean fuels increases in response to disclosure programs. However, the programs also produce unintended consequences. Customer composition and pre-existing fuel mix significantly affect program response, suggesting that effective information disclosure policies may not be efficient.
