The Review Of Operational Risk Measuring Models (Id : 5-038)

The paper overviews the measuring models about operational risk measurement. It divides the research into two parts: abroad and home. In abroad, Basel committee gives three main methods that are:'Basic Indicator Approach, Standardized approach and IMA. The paper also talks about other models, such as CAPM, OpVaR, Scorecard Approach, Scenario-based Approach, Loss distribution approach, Bayesian networks, Fuzzy logic and neural network, Multifactor modeling, Extreme value theory. Also it compares these models. So, it considers that the research of operational risk in foreign starts early and has probed many methods. In domestic, the research is starting, and most are translation of foreign, so researchers have not informed their own view. There are two present in domestic who are Yang xiaoguang and Zhong wei. Yang xiaoguang put emphasis on empirical analysis, and zhongwei prefers to theory research. It considers that data (especially historical data) missing is the biggest obstacle in OR measurement. So, it is necessary for world institutions and enterprises to build OR database and find out the efficient and possible method to measure OR in practice.
