Globalization and affordability of microfinance

We study how globalization can differentially affect financial inclusion through the lens of microfinance. Based on an institutional logics perspective, we argue that MFIs embody both social logic and market logic with regard to provision of affordable microfinance loans. Speicially, social logic is amplified by greater social globalization and the stronger presence of nonprofit organizations (NPOs) in the microfinance industry. In contrast, economic globalization catalyzes MFIs' market logic, leading to weaker or greater affordability of microfinance, depending on the relative strength of the profit-maximizing motive and real competition. We test these predictions by focusing on MFI interest-rate setting and using longitudinal data from 2030 MFI observations across 50 countries from 2002 to 2012. We find that country-level social globalization measure is negatively associated with the average MFI loan interest rates and that country-level economic globalization measure has an inverse U-shaped relationship with the average MFI loan interest rates. These results support our hypotheses and suggest a more nuanced view on how globalization affects affordability of microfinance.     

Revisiting the risk-return relation in the Chinese stock market: Decomposition of risk premium and volatility feedback effect

The empirical results of the risk-return relationship are mixed for both mature and merging markets. In this paper, we develop a new volatility model to revisit the risk-return relation of the aggregate stock market index by extending the Realized GARCH model of Hansen et al. (2012) with the Wang and Yang (2013) framework, in which the overall risk-return relation is decomposed into a risk premium and a volatility feedback effect. An empirical analysis of three major Chinese stock indices reveals positive risk premium and negative volatility feedback effect, and those findings are stable across different markets and sub-samples. However, their relative magnitudes differ between markets and varies through time.     

粮食中镉含量测定方法初探:以石墨炉原子吸收分光光度计法为例

笔者长期从事粮食中镉污染检验工作,大量实践经验表明,虽然原子吸收仪的品牌、型号各不相同,但应用原理、结构大致相同。本文以石墨炉原子吸收分光光度计法对粮食中镉的含量的检测为例进行说明,发现试样前处理、试剂空白、使用试剂、回收实验及在操作过程中的对仪器的处理等对检测结果均会产生直接影响。为确保检测结果准确性,本文对检测过程中影响检测结果的各注意事项进行了分析总结,希望能对从事镉污染检测工作的人员提供理论指导和借鉴。     

Does IFRS Adoption Increase the Accuracy of Chinese Analysts’ Forecasts?

This article investigates the impact of International Financial Reporting Standards (IFRS) adoption on the accuracy of Chinese analysts’ earnings forecasts. We find that after IFRS adoption, the accuracy of Chinese analysts’ forecasts decreases rather than increasing as they do in developed countries documented by the extant literature. Further investigation finds that this decrease is associated with a fair value measurement of financial assets held for trading. Our finding provides empirical evidence supporting the argument that the effectiveness of IFRS adoption could be negative in a developing country depending on its setting and fair value measurement brought about by IFRS could contribute to the negative effect in this setting.     

Shanxi Merchants’ Multilevel Financial System in Ming and Qing Dynasties,China

In the Ming and Qing Dynasties (1368–1911), China saw rapid development in industrial and commercial sectors. Over this period, a group of merchants originating from the inland province of Shanxi gradually built a multilevel financial system and became leaders in China’s banking sector. The system of financial institutions they established (pawnshops, seal shops, money shops, loan banks, and draft banks) each had a unique business model, with specific target client group and carefully designed risk management. They were also interconnected to allow for flexible capital flows, contributing to the fast economic growth in this period. Nevertheless, the traditional system also had limitations, leading to its replacement by modern banks eventually.

价值共创行为分析框架构建 ——基于赋能理论视角

通过文献调查并结合案例的描述性分析,提出数字技术时代价值网络中不同行为主体之间的赋能内涵、关键维度以及基于赋能跨层次效应的价值共创行为分析框架。将"赋能氛围""主体赋能"分别作为价值网络中赋能的宏观维度和微观维度进行概念化。界定了两个维度的关键组成要素,分别包括信息共享、开放性结构、协同规则以及主体关系、资源整合和影响。构建了赋能的跨层次效应模型,分析了赋能的宏观-微观跨层次效应及其对价值网络生态和主体价值创造的影响。
