Many firms conduct “environmental audits” to test compliance with a complex array of environmental regulations. Commentators suggest, however, that self-auditing is not as common as it should be, because firms fear that what they find will be used against them. This article analyzes self-auditing as a two-tiered incentive problem involving incentives both to test for and to effect compliance. After demonstrating the inadequacy of conventional remedies, we show that incentives can be properly aligned by conditioning fines on firms’ investigative effort. In practice, however, the regulator may not be able to observe such effort. Accordingly, we propose and evaluate the use of three observable proxies for self-investigation: the manner in which the regulator detected the violation; the firm’s own disclosure of violations; and the firm’s observed corrective actions. Each method has its own efficiency benefits and informational requirements, and each is distinct from EPA’s current audit policy.

The Kyoto Protocol & Payments for Tropical Forest: An Interdisciplinary Method for Estimating Carbon-Offset Supply and Increasing the Feasibility of a Carbon Market under the CDM
Protecting tropical forests under the Clean Development Mechanism (CDM) could reduce the cost of emissions limitations set in Kyoto. However, while society must soon decide whether or not to use tropical forest-based offsets, evidence regarding tropical carbon sinks is sparse. This paper presents a general method for constructing an integrated model (based on detailed historical, remote sensing and field data) that can produce land-use and carbon baselines, predict carbon sequestration supply to a carbon-offsets market and also help to evaluate optimal market rules. Creating such integrated models requires close collaboration between social and natural scientists. Our project combines varied disciplinary expertise (in economics, ecology and geography) with local knowledge in order to create high-quality, empirically grounded, integrated models for Costa Rica.
Historical data from the late 19th to the early 20th century are examined for New England. From the attempt to explain the reforestation that occurred, three main land-use claims arise: 1) population clearly does not fully dictate land use (e.g., de- or re-forestation); while population may well have an independent effect on land use, that effect clearly does not dominate all others; 2) factors that affect relative land-use returns, whether “external” to a region or not, clearly do affect land use; two examples are transport costs and productivity of other regions, which affect trade; and finally, 3) long-run analysis must consider shifts even in overall framework, such as from agriculture to migration and industrialization processes involving different economic dynamics. Support for these claims comes from limited historical data alongside relevant theory concerning optimal allocation of land between the four most relevant land uses: agriculture, manufacturing, forest (for timber or as a result of abandonment), and shelter (or, more generally, land uses other than for production). Supporting the “population” claim, previous New England farm expansion flattened out post-1850 and eventual reversed itself, even as population was increasing. Regarding the “returns” claim, the breakpoint in the 1790-1930 series of within-region measures (based on county-level data) of concentration of population is very clearly at about 1830, precisely the era in which the transportation revolution involving railroads, steamships and canals started to have its effect. Concerning the “long-run” claim, given an interest in land use there are grounds for attention to shifts in regional output, such as towards manufacturing from agriculture, as there is evidence that such shifts involved significant changes, in particular concentration of population within particular counties, along rivers and in particular locations along rivers.
