信息化助推白沙管理升级

<正>几年前刚刚上任的总裁卢平女士发现:每次出差回来,桌上的文件就堆得像小山;年终总结时,交上来的材料都是厚厚一叠。她于是规定:凡是给她看的东西,只能是一张纸,上面直截了当地写明“题目、问题、方案、机遇、风险、结论和审批”。后来这家企业将“一张纸制度”逐渐归纳提炼为“简约管理”四个字。

Exit Options in Corporate Finance: Liquidity versus Incentives

This paper provides a first study of the optimal design of active monitors'exit options in a problem involving a demand for liquidity and costly monitoring of the issuer. Optimal incentives to monitor the issuer may involve restricting the monitor's right to sell her claims on the firm's cash-flow early. But the monitor will then require a liquidity premium for holding such an illiquid claim. In general, therefore, there will be a trade off between incentives and liquidity. The paper highlights a fundamental complementarity between speculative monitoring in financial markets (which increases the informativeness of prices) and active monitoring inside the firm: in financial markets where price discovery is better and securities prices reflect the fundamentals of the issuer better, the incentive cost of greater liquidity may be smaller and active monitoring incentives may be preserved. The paper spells out the conditions under which more or less liquidity is warranted and applies the analysis to shed light on common exit provisions in venture capital financing.     

METROPOLITAN HOUSE PRICES IN SOUTH AFRICA: DO THEY CONVERGE?

The question this paper investigates is whether or not different metropolitan areas each constitute a separate housing market or whether or not there is a single South African housing market. Theory on the Law of One Price suggests that if products or geographic areas belong in the same market, their absolute prices must converge, so that their relative prices are stationary. By using cross-sectional time series data of five metropolitan areas, the paper tests for the Law of One Price by applying the Im, Pesaran and Shin panel unit root test. The paper finds strong evidence of convergence in large middle-segment house prices and weaker support for convergence in medium middle-segment house prices. In addition, the paper finds no evidence for convergence in small middle-segment house prices. This suggests the existence of a national market for large and possibly middle-segment houses in metropolitan areas, but separate metropolitan markets for small middle-segment houses. In addition, the paper estimates the speed of convergence and finds that large middle-segment house prices converge within two to seven quarters, while the speed of convergence for medium middle-segment house prices in three of the five areas is five to eight quarters.     

国际产业转移与中国产业结构的协整分析

国际产业转移包括国外直接投资和对外贸易两种主要方式。文章以我国1983—2006年的数据，对第二产业比例、国外直接投资和对外贸易进行协整检验和格兰杰（Granger）因果检验。研究表明，第二产业比例、国外直接投资和对外贸易之间存在长期均衡关系，而且，国外直接投资和对外贸易是第二产业比例的Granger原因。因此，国际产业转移对我国产业结构调整具有重要影响。
