The Fundamental Review of the Trading Book: Implications for Portfolio and Risk Management in the Banking Sector

The Fundamental Review of the Trading Book (FRTB) is the promised overhaul of bankmarket risk regulation. FRTB retains the authorized use of proprietary risk models, however, it introduces two additional criteria: (i) P&L attribution (PLA) tests and (ii) desk-level backtests. We examine empirically whether these additional criteria influence risk management and portfolio management practice, specifically portfolio construction and choice of risk model. We find that the PLA tests demand significant alignment with risk factors, however, the backtests do not incentivize use of superior risk models. This has important implications for the efficacy of the capital-based regulatory system.     

Review: Food loss and waste in Sub-Saharan Africa

The research, development practitioner, and donor community has begun to focus on food loss and waste – often referred to as post-harvest losses (PHL) – in Sub-Saharan Africa. This article reviews the current state of the literature on PHL mitigation. First, we identify explicitly the varied objectives underlying efforts to reduce PHL levels. Second, we summarize the estimated magnitudes of losses, evaluate the methodologies used to generate those estimates, and explore the dearth of thoughtful assessment around “optimal” PHL levels. Third, we synthesize and critique the impact evaluation literature around on-farm and off-farm interventions expected to deliver PHL reduction. Fourth, we suggest a suite of other approaches to advancing these same objectives, some of which may prove more cost-effective. Finally, we conclude with a summary of main points.

Our analysis also identifies the most often cited articles at different points in the journal's history. Using textual data analytics, we identify the most frequent themes discussed between 1969 and 2018 by decade.     

基于大数据环境的财务报销自动审核系统构建

为了有效地解决当前企业财务报销审核系统中审核差错大、运行效率低的问题,在大数据分析的基础上,对自动财务报销审核系统进行了优化。结合数值概率算法,对大量财务报销数据进行合理分类,并将分类后的数据传输到财务项目配置模块进行审批。优化财务审核安全评价流程,检查审核处理结构的准确性。对系统服务器和处理器模块的硬件配置进行了优化,达到了优化财务自动报销审核运行效果和准确性的设计目标。实验证明,基于大数据分析的财务报销自动审核系统的财务审核差错率较传统系统明显降低,系统运行效率较传统审核系统提高20%-50%。     

Annual report readability and corporate agency costs

Annual reports are the main sources of information for outside investors’ investment decisions and enable shareholders to supervise the management. Difficulties with the readability of these reports may therefore have serious consequences. Using 19,221 firm-year observations of Chinese A-share listed firms from 2001 to 2015, we investigate the association between annual report readability and corporate agency costs, where readability is proxied by report file length and/or file size. We find that firms with better annual report readability experience lower agency costs, and the negative association between readability and agency costs is more pronounced in firms with higher external audit quality, internal control quality or analyst coverage. These results hold after several robustness checks. The positive effect of annual report readability is stronger in private firms than in state-owned enterprises, and becomes stronger after the implementation of new accounting standards in 2007. Readable annual reports can help in monitoring corporate insiders’ opportunistic behavior and thus reduce agency costs.
