Advertising,Price and Quality in Self–regulating Professions: A Survey

This paper surveys the theoretical and empirical literature on the relationship between advertising, fees and quality in the self–regulating professions. Much of the literature is derived from the perspective of advertising as an information–enhancing device, helping to reduce the information asymmetry between professional and client. This is consistent with the majority of the empirical studies which suggest that advertising tends to have a downward effect on professional fees, with little if any adverse effect on quality. There are, however, important issues of method and measurement which may lessen the force of this conclusion     

The Analysis and Improvement on the Lowest Price Method

The book of Modem Consulting Method and Practice is the appointed teaching material for registered consulting engineer qualification examination （investment） of China. Its Lowest Price method in evaluating mutually exclusive project has some problems, which contradict the delta IRR and NPV methods. We improve the method and recommend Good-Bad Boundary Price Method to solve problem of this type.     

Some Evidence on the Adjustment of Producer Prices*

We document producer price adjustment using a low‐inflation micro price dataset. On average 24% of prices adjust each month, with an average increase/decrease of 6%. Producer prices adjust more frequently than consumer prices, but their size of adjustment is typically smaller. Sectoral heterogeneity in the frequency of price adjustment is strongly related to heterogeneity in the cost structure. Fluctuations in aggregate producer price inflation occur to a large extent through variation in the relative share of upward and downward price adjustment.     

Short sales, price pressure, and the stock price response to convertible bond calls

The announcement of a convertible bond call is associated with an average contemporaneous abnormal stock price decline of 1.75% and an ensuing price recovery in the conversion period. A price fall and the subsequent recovery suggest price pressure as the explanation for the announcement effect. However, in general the option to convert is not exercised early and hence, the increase in the number of shares outstanding does not occur at the announcement date. Instead, this paper argues and provides evidence that hedging-induced short selling causes at least part of the short-run price pressure.     

竖向地震力的冲量计算法

一般认为地震在地表引起的破坏主要是S波的水平震动,很少考虑地震竖向力的作用。单从考虑地震水平力的作用是不易全面反映震害特征的。提出用冲量法来研究计算竖向地震力,通过对最大竖向地震力分布研究,探讨竖向地震力对建筑物的影响与破坏,为进一步提高工程抗震设计水平提供理论依据。     

信息冲击对收益波动的影响--基于交易量的实证研究

文章首先将交易量分解为信息交易量和非信息交易量，然后将信息交易量加入广义自回归条件异方差模型（GARCH模型），来分析信息对收益波动的影响。结果发现，信息冲击对收益波动的影响十分显著，投资者对信息到达的反应存在过度反应、过度矫正、适度反应的过程。     

公司价值评估中管理者柔性的价值评估研究

现在公司价值评估方法往往没有考虑到对管理柔性价值定价问题。由于管理柔性价值定价是一种类似期权的定价，因此本运用Black—Scholes期权定价模型和买权卖权平价关系，定价管理柔性价值，来完善公司价值评估中的折现现金流量模型。

我国矿产资源开发利用现状与发展策略

矿产资源是人类赖以生存发展的物质基础,在现代化建设中占有重要的地位。我国是世界上矿产资源比较丰富、矿种比较齐全的少数几个国家之一。具有资源总量丰富但人均占有量少;矿床规模有大有小;贫矿多且富矿少等特点。多年来由于矿产资源的不合理开发利用,造成严重的环境污染。在我国许多地区废矿石大量堆放,地表水和地下水严重污染,区域地下水位下降,土壤和空气也受到侵害。为保证２１世纪我国国民经济的持续发展,必须采取以下几个方面的对策：①加强和改善矿产资源的管理;②加强地质勘查工作,增加矿产资源探明储量以适应国民经济的发展;③实行开源与节流并重的方针,走资源节约型发展经济的道路;④充分认识我国矿产资源的产出特点,完善矿产开发的产业机制;⑤依靠法制和科学管理,有效控制环境污染,保护矿产资源。
