Fraud Risk Assessments

SUMMARY In this paper, we provide a practitioner summary of our paper “The Influence of Judgment Decomposition on Auditors' Fraud Risk Assessments: Some Trade-Offs” (Simon, Smith, and Zimbelman 2018). In that study, we investigate potential unintended consequences from current auditing guidance on risk assessments. Specifically, auditing standards recommend separate assessments of the likelihood and magnitude of risks (hereafter, LM decomposition) when auditors assess risk. Our study involved several experiments, including one with experienced auditors, where we found evidence that LM decomposition leads auditors to be less concerned about high-risk fraud schemes relative to auditors who make holistic risk assessments. Our other experiments involved non-auditing settings and replicated this finding while exploring potential explanations for it. After providing a summary of our study and its results, we offer concluding remarks on the potential implications of our findings.

<p>Aviation aims to reduce its climate impact by identifying promising mitigation options which are able to reduce the overall climate effects of aviation considering CO<sub>2</sub> and non-CO<sub>2</sub> effects. While aiming to identify fuel optimal trajectories, aviation also aims to reduce the non-CO<sub>2</sub> effects comprising NO<sub>x</sub>-induced changes of atmospheric ozone and methane. Here climate-chemistry models are required which are able to quantify perturbations in atmospheric composition of reactive species (NO<sub>x</sub>, O<sub>3</sub>) and the associated radiative forcings of aviation emissions relying on advanced modelling capabilities, realistic emission inventory data and global-scale observational datasets from research infrastructures like IAGOS and DLR aircraft measurement campaign data.</p> <p>We use the multi-scale climate-chemistry MECO(n) system which is a “MESSy-fied ECHAM and COSMO nested n-times”, relying on the Modular Earth Submodel System (MESSy) framework. For this purpose, both models have been equipped with the MESSy infrastructure, implying that the same process formulations (MESSy submodels) are available for both models. Modelled atmospheric distributions are systematically compared to observational data from aircraft measurements in the upper troposphere and lower stratosphere. Nudging of meteorology to ERA5 interim data, and special diagnostics available within the modular MESSy infrastructure are implemented in the numerical simulations. Online sampling along aircraft trajectories allows to extract model data with a high temporal resolution (MESSy submodel S4D), in order to evaluate model representation and key processes.</p> <p>Beyond systematic evaluation with IAGOS scheduled aircraft measurements, episodes will be evaluated where dedicated measurements from aircraft campaigns are available, comprising Spring 2014 (ML-CIRRUS campaign), early summer 2020 (Blue Sky campaign) and summer 2021 (Cirrus-HL campaign). Our analysis of reactive species, NO<sub>y</sub> and ozone, identifies those weather pattern and synoptic situations where aviation contributes strong signals, resulting in recommendations on measurement strategies to detect aviation signal in the atmosphere. We evaluate model representation of the NO<sub>x</sub>-induces effect on radiatively active species ozone and methane in both model instances, ECHAM5 and COSMO. This is key for advancing the scientific understanding of NO<sub>x</sub>-induced effects from aviation which is required in order to quantify potential compensation and trade-offs when identifying robust mitigation options for sustainable aviation.</p> <p>This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 875036 (ACACIA, Advancing the Science for Aviation and Climate) and has been supported by the DLR-Projekt Eco2Fly.

PurposeThis study aims to illuminate the challenges involved in implementing community benefits (CBs), a sustainable public procurement policy that ensures that there are positive social and economic outcomes for the local community when public money is spent on goods, works and services.Design/methodology/approachInterviews and focus groups were conducted with public sector buyers and suppliers in Wales with experience in implementing CBs. Resource dependence theory was used to examine the extent to which dependence on resources effects CBs implementation.FindingsWhilst the study confirms that implementation of CBs improves economic and social outcomes, there can also be challenges for public sector organisations and their constituent supply chains. These include tensions between CBs and other policies, differing views between buyers and suppliers, and the unintended consequences of promoting one form of CBs over another.Research limitations/implicationsThe research found that Welsh Government influences the buyer-supplier dyad through regulatory and financial power. We elaborate on resource dependency theory by adding four constructs (powerful stakeholders, intra and inter organisational issues, challenges and enablers) to better understand the flows of power and resources in this research context.Practical implicationsBuyer and supplier practitioners and policymakers may find the factors leading to successful CBs implementation useful, such as ensuring closer communication and liaison at early contract stages.Social implicationsCommunity benefits are aimed at improving socioeconomic issues through public procurement.Originality/valueThis study addresses the need for research into how public sector organisations and suppliers seek to implement socio-economic sustainability measures, and the lack of research on CBs implementation to date. It is also novel in adopting a dyadic approach and a resource dependency perspective.
