虚拟经营条件下企业信息处理的过程分析与建构

虚拟企业信息处理是企业内部和企业之间的信息通过计算机网络途径进行传输的运动过程，形成网络化集成的信息处理过程，是对商品或服务运动状态的直接反映。本文提出虚拟化经营条件下企业信息流的组成和特点，从层次环境和战略规划分析虚拟企业信息处理的影响因素，并对VE信息处理过程进行建模，形成网络化企业组织信息全过程管理的方法体系。     

Information Asymmetry and Asset Prices: Evidence from the China Foreign Share Discount

We examine the effect of information asymmetry on equity prices in the local A‐ and foreign B‐share market in China. We construct measures of information asymmetry based on market microstructure models, and find that they explain a significant portion of cross‐sectional variation in B‐share discounts, even after controlling for other factors. On a univariate basis, the price impact measure and the adverse selection component of the bid‐ask spread in the A‐ and B‐share markets explains 44% and 46% of the variation in B‐share discounts. On a multivariate basis, both measures are far more statistically significant than any of the control variables.     

液相色谱-串联四级杆质谱方法检测动物源性基质中的β2——受体激动剂

利用安捷伦6410高效液相色谱串联质谱（LC／MS／MS）方法快速、准确地测定多种β2-受体激动剂的残留量。串联质谱在电喷雾（ESI＋）,多反应监测（MRM）模式下,进行质谱定性和定量分析,比液相检测方法灵敏、快速。该方法的定量检测限（LOQ）大多在0．5μg／kg以下,完全可以达到欧盟和日本对β2-受体激动剂残留限量的要求。     

EXPLOITING UNCERTAINTY—INVESTMENT OPPORTUNITIES AS REAL OPTIONS: A NEW WAY OF THINKING IN ENGINEERING ECONOMICS

A new trend in corporate planning is to exploit uncertainty by taking investment opportunities as real options. This options approach is to complement the conventional net present value (NPV) criterion in evaluating risky investments. In this paper, we take a broad look at the real options approach to various engineering economic decision problems, laying out how it provides an immediate and important perspective on value creation in an uncertain world. Unlike financial options, real options analysisdeals with investments in real assets, which is one of the primary interest areas in engineering economics. For that reason, we believe that any advancement in the real options decision framework will benefit the field of engineering economics.     

A New Model of Inflation,Trend Inflation,and Long‐Run Inflation Expectations

This paper develops a bivariate model of inflation and a survey‐based long‐run forecast of inflation that allows for the estimation of the link between trend inflation and the long‐run forecast. Thus, our model allows for the possibilities that long‐run forecasts taken from surveys can be equated with trend inflation, that the two are completely unrelated, or anything in between. Using a variety of inflation measures and survey‐based forecasts for several countries, we find that long‐run forecasts can provide substantial help in refining estimates and fitting and forecasting inflation. It is less helpful to simply equate trend inflation with the long‐run forecasts.     

Collateral and Competitive Equilibria with Moral Hazard and Private Information

The authors examine equilibrium credit contracts and allocations under different competitivity specifications and explain the economic roles of collateral under these specifications. Both moral hazard and adverse selection are considered. The principal message is that how a competitive equilibrium is conceptualized significantly affects the characterization of equilibrium credit contracts. Specifically, some well-known results in the rationing literature are shown to rest delicately on the adopted equilibrium concept. Two somewhat surprising results emerge. First, high-quality borrowers with unlimited collateral may be priced out of the market despite the bank having idle deposits. Second, high-quality borrowers may put up more collateral.

MAKING SENSE OF THE ‘BUSINESS GROUP’ IN MODERN CHINA: THE RONG BROTHERS' BUSINESSES, 1901–37

Some China scholars have suggested that ‘business groups’ in pre‐Communist China adopted a ‘hierarchical’ structure of management. This perception is re‐examined in a study of the inter‐firm relationship among the firms in which the Rong brothers, prominent industrialists of the 1910–30s, invested. We find that equity control, marketing, purchasing, and financing of these firms show a high degree of individuality among the firms, while the Headquarters Company functioned as their coordinator. It suggests that the hierarchical‐controlled ‘business group’ structure in pre‐war China is either a phantom creation of historians or the projected image of later generations who created it during the nationalisation of firms in the 1950s.
