Best classification algorithms in peer-to-peer lending

A proper credit scoring technique is vital to the long-term success of all kinds of financial institutions, including peer-to-peer (P2P) lending platforms. The main contribution of our paper is the robust ranking of 10 different classification techniques based on a real-world P2P lending data set. Our data set comes from the Lending Club covering the 2009–2013 period, which contains 212,252 records and 23 different variables. Unlike other researchers, we use a data sample which contains the final loan resolution for all loans. We built our research using a 5-fold cross-validation method and 6 different classification performance measurements. Our results show that logistic regression, artificial neural networks, and linear discriminant analysis are the three best algorithms based on the Lending Club data. Conversely, we identify k-nearest neighbors and classification and regression tree as the two worst classification methods.     

高管薪酬、董事会治理与分类转移

本文研究了高管薪酬和董事会治理对分类转移的影响。研究表明,货币薪酬会诱使高管向上转移利得,股权激励和缺乏区分度的薪酬制度会诱使高管同时向下转移费用和向上转移利得;而勤勉、独立和两职分离的董事会能够在一定程度上识别并抑制这两种不同方式的分类转移;但董事会对分类转移的抑制程度小于高管薪酬对分类转移的诱发程度。进一步地,良好的市场、法制和媒体监督环境能够有效缓解高管薪酬对分类转移的诱发作用,而董事会能够有效弥补法制建设和媒体监督不足导致的分类转移治理缺陷,并在较高质量的审计环境下对分类转移发挥更强的抑制作用。本文首次结合制度背景和媒体监督研究了公司核心治理机制对不同分类转移方式的影响和原因,并创新性地对向上转移利得的程度进行了衡量,为监管部门及公司治理机制、会计准则的制定者提供经验证据。     

Does health insurance decrease health expenditure risk in developing countries? The case of China

This article studies the impact of health insurance on individual out‐of‐pocket health expenditures in China. Using China Health and Nutrition Survey data between 1991 and 2006, we apply two‐part and sample selection models to address issues caused by censored data and selection on unobservables. We find that, although the probability of accessing health care increases with the availability of health insurance, the level of out‐of‐pocket health expenditure decreases. Our results from a selection model with instrumental variables suggest that having health insurance reduces the expected out‐of‐pocket health expenditure of an individual by 29.42% unconditionally. Meanwhile, conditional on being subjected to positive health expenditure, health insurance helps reduce out‐of‐pocket spending by 44.38%. This beneficial effect of health insurance weakens over time, which may be attributable to increases in the coinsurance rates of health insurances in China.     

Exploring the multi-dimensionality of authenticity in dining experiences using online reviews

The quest for authenticity in dining experiences has become increasingly important. This paper explores authenticity dimensions that are of value to customers in dining experiences, and by that gains a multi-dimensional understanding of authenticity in this context. Following an integrated learning approach using text mining and classification techniques, this paper explores and confirms different dimensions of authenticity by identifying and classifying authenticity judgements in online restaurant reviews. The results suggest that authenticity is a multi-dimensional concept encompassing Authenticity of the Other, Authenticity of the Producer, and Authenticity of the Self as first-level dimensions. Additionally, besides historical and categorical authenticity which have been previously explored in the literature, a new type of authenticity - Deviated Authenticity - emerged as a second-level dimension falling under Authenticity of the Other. This paper enhances existing conceptualisations of authenticity and establishes avenues for exploring the multi-dimensionality of other consumer research concepts using user-generated content.     

New development: A new COFOG for South Korea

The South Korean government's Classification of the Functions of Government (COFOG) is grounded in the System of National Accounts (SNA), rather than Government Finance Statistics (GFS). This article explains why a GFS-based classification might be beneficial to South Korea for the purposes of fiscal management and the comparison of government expenditures with other countries.     

If You’re Going Through Hell,Keep Going: Nonlinear Effects of Financial Liberalization in Transition Economies

Did increasing the level and pace of financial liberalization during transition expose countries to crises? And if a crisis did strike, did liberalization do more harm or good? Using a database of 28 transition economies over 22 years, this article examines these questions across a host of economic outcomes, including savings and the size of the private sector. The results provide evidence that, while liberalization may initially increase the probability of a crisis, the prospect of a crisis drops dramatically at higher levels of financial openness. Moreover, the benefits of liberalization across several metrics outweigh the risks of these intermediate stages.     

Earnings management using classification shifting of revenues

This paper examines a novel form of classification shifting as an earnings management tool using a sample of 12,804 UK listed firm-year observations for the 1995–2014 period. It proposes a new approach to classification shifting whereby firms have scope to misclassify revenues from non-operating activities as operating revenues. The results establish that firms engage in classification shifting of non-operating revenues to inflate operating revenues. They indicate that firms in the period following mandatory IFRS adoption are associated with an increase in this practice, consistent with IFRS offering greater scope for manipulation. Further tests reveal that classification shifting of revenues is more pervasive for firms that report operating losses or have low growth.     

知识活动视角下企业大学类型及其支撑能力体系

基于知识视角，任何组织开展的活动均可视为知识活动。企业大学所从事的知识活动不仅包括知识转移活动，还包括知识创造活动和应用孵化活动，不同企业大学开展的知识活动不同，对以上3类知识活动的主导程度也不同。借鉴扎根分析流程，通过多案例研究梳理企业大学的里程碑事件，对企业大学的知识活动类型进行理论提炼并总结相应能力支撑体系。结果发现：①企业大学模式类型并不绝对而是多元的，随着企业大学知识活动的不断丰富和延伸，逐渐演化为不同模式类型;②知识转移活动并非是企业大学唯一的知识活动路径，不宜忽视企业大学知识活动的全息性特征;③企业大学为了更好地履行职能，还应树立支撑能力组合观念，尤其应该按照企业大学知识活动特性和规律构建相应关键能力支撑体系。     

Key institutions in business and management education research

The authors investigate institutional productivity in business and management education (BME) research based on the analysis of 4,464 articles published by 7,210 authors across 17 BME journals over a 10-year period, involving approximately 1,900 schools worldwide. Departing from traditional disciplinary silos, they examine the BME research field as a whole by including all traditional business disciplinary areas and producing two top 100 rankings, one based on raw number of author publications and the other based on weighted scores reflecting journal quality and coauthorship.     

Openness of the economy,terms of trade,and arms

It is estimated that world military spending in 2011 amounted to over 2.5% of the world's Gross Domestic Product (GDP). This corresponds to a spending of $233 per person in the world at 2010 constant prices, an amount close to the GDP per capita of the poorest country in the world. Therefore, it is important for economists to understand the allocation of resources to this sector of the economy. I present a model that explores the determinants of a country's level of military spending. I show how greater gains from trade can lead to greater military expenditures to protect them. It is also found that expansion in the demand for a country's tradable commodities, that is, an improvement in that country's terms of trade, will impact defense spending. Several other propositions emerge from the model which are then empirically tested using both pooled and time series data. The statistical results support the model's propositions.
