DETECTING EVIDENCE OF NON-COMPLIANCE IN SELF-REPORTED POLLUTION EMISSIONS DATA: AN APPLICATION OF BENFORD'S LAW AgEcon
Dumas, Christopher F.; Devine, John H..
The paper introduces Digital Frequency Analysis (DFA) based on Benford's Law as a new technique for detecting non-compliance in self-reported pollution emissions data. Public accounting firms are currently adopting DFA to detect fraud in financial data. We argue that DFA can be employed by environmental regulators to detect fraud in self-reported pollution emissions data. The theory of Benford's Law is reviewed, and statistical justifications for its potentially widespread applicability are presented. Several common DFA tests are described and applied to North Carolina air pollution emissions data in an empirical example.

Estimation and Analysis of Expenses of In-Lieu-Fee Projects that Mitigate Damage to Streams from Land Disturbance in North Carolina AgEcon
Templeton, Scott R.; Dumas, Christopher F.; Sessions, William T.; Victoria, Melanie.
As North Carolina’s economy has grown, the need to mitigate adverse impacts of land disturbance on aquatic ecosystems has also grown. When land disturbance adversely affects streams, a developer or the state’s Department of Transportation can satisfy mitigation requirements through payment of fees to the state’s Ecosystem Enhancement Program (EEP). EEP then manages a stream mitigation project on behalf of the responsible party. EEP has had regulatory authority to require stream mitigation for 10 years. The needs of EEP to reassess its mitigation fee and identify ways to reduce costs of the program have grown over the decade. The first objective of this study was to account for all EEP expenses of design-bid and design-bid-build projects. The second...

THE COTTON ACREAGE EFFECTS OF BOLL WEEVIL ERADICATION: A COUNTY-LEVEL ANALYSIS AgEcon
Dumas, Christopher F.; Goodhue, Rachael E..
The success of the Boll Weevil Eradication (BWE) Program is believed to be one factor underlying the recent increase in cotton acreage in the Southeast. We find weak evidence that the initial, eradication phase of the BWE program decreases cotton acreage, and strong evidence that the second, maintenance phase of the program increases acreage. The full benefits associated with a BWE program may not become apparent until acreage adjustments occur, four to five years after program initiation. Our results indicate that for a representative sample county neglecting acreage effects may lead to underestimation of BWE program net benefits by 9 percent-12 percent.
Tipo: Journal Article Palavras-chave: Acreage effects and policy evaluation; Boll weevil eradication program; Cotton; Integrated pest management (IPM); Crop Production/Industries.
