Does the Company Lawyer Have Your Back? A Brief Look at the Need for Personal Private Liability Insurance

There are four traditional uses of private personal liability insurance dating from the 1970s to the present (Hayes 1979; Sommers 2005) which pertain either to individuals or corporations. There is insurance to cover damage to rental cars, umbrella insurance to cover any injury to a guest at one’s home, insurance bought by corporations to cover potential corporate responsibility for actions of company representatives and insurance including misadventures with financial information and morally hazardous behavior as well as corporate required actions which are later deemed to be wrong or inappropriate. Employees need to find out if the employee manual provides for coverage for legal liabilities resulting out of performing job responsibilities. Due to a need to reduce company costs, many companies are reducing or eliminating coverage for employees for many types of actions. Private personal liability insurance gives you the peace of mind to know what you are covered for and for how long. Employee rights versus corporate budgets are at the core of this discussion.     

经济全球化下的产业结构演进趋势与政策

本文提出近20年来中国产业结构演进的U型轨迹假说，并予以验证。论文比较了U型轨迹与同期政府产业结构政策的关系，指出我国近20年来产业结构的演变与各相应时期的政府产业结构政策之间，不存在密切的因果关系，相反，开放市场经济中的全球化市场力量具有更大的影响，在经济全球化尤其是中国加入WTO大背景下，产业结构政策是一种无效的经济政策，与此同时，产业结构则继续根据经济发展的内在规律而不断演进。     

Optimal Intervention Policies for a Small Monetary Economy

We analyze the gains from trade for a small cash-in-advance economy with endogenous labor supply and learning-by-doing in the accumulation of human capital. Contrary to previous findings, we show that free trade is not optimal independently of the relative amount of cash required for the purchase of each good. Furthermore, a monetary rule à la Friedman can eliminate distortions deriving from the cash-in-advance constraint only under segmented financial markets; in any case, it cannot restore the economic optimum. Finally, we identify government intervention policies, such as wage and export subsidies, that can be welfare improving.

存货会计政策与成本流动假设的经济学分析

存货是大多数企业的重要流动资产,基于不同的成本流转假设理论,存货计价方法一般可划分为具体辨认法、平均成本法、先进先出法、基本存货法、后进先出法等。存货会计政策选择具有广泛的经济后果,影响企业的财务状况、收益质量、税收成本、现金流量、经营者业绩与其报酬、公司股票价格及报表使用者理解会计信息等。本文认为,各种存货计价政策对企业净利润产生的差异均属于“时间性差异“,在若干个会计期间内,企业无论选择何种会计政策,产生的净利润和经营性现金流量都应该是相等的,企业之所以进行会计政策选择是为了取得上述会计数据不同时间分布带来的各种可能的经济利益。     

中国货币政策传导机制分析——利率渠道的实证分析

市场经济条件下，在发达的货币市场和有效的金融机制基础上，货币政策主要通过利率、汇率、非货币资产和信贷传播四条途径影响宏观经济总量。本文重点通过对利率传导渠道的实证分析，说明中国由于利率管制等方面对货币政策传导的阻滞作用，中央银行的货币政策意图不能有效地指导实体经济，进而对疏导货币政策的传导机制提出对策建议。     

全球贸易自由化下的环境问题与环境政策

在全球贸易自由化的进程中，对环境既产生了正的影响，也产生了负的影响。但贸易不是产生环境问题的根源，所以不能靠制定与贸易有关的环境政策来解决，而应当在环境污染的发生地实施有关的环境政策，使“外部化”了的费用，纳入生产者的成本中，这才是真正的贸易比较优势。     

西方产业竞争政策的体系和目标

本文讨论美国、欧共体和日本的竞争政策的方法和体系的差异问题。美国的竞争政策侧重于追求消费者剩余和生产者剩余最大化 ,强调通过竞争的作用来达到这一经济效率目标。欧共体的竞争政策则强调在消费者福利的基础地位 ,通过协调竞争规则来促进欧共体经济一体化的进程。日本的反垄断法原本从西方吸收过来的 ,经过半个世纪的发展和演变 ,已经具有明显的日本特色 ,其基本功特征是对价格机制的运作缺乏信任 ,对规模经济神话的盲目崇拜和信任 ,结果是经常提倡和鼓励那种必然会导致寡占市场结构的兼并活动。     

Externalities,Cross-Sectoral Spillovers and Productivity Growth

We provide an interpretation of the productivity dynamics in the manufacturing sector based on the idea of the thick market externality à la Diamond. An econometric model has been estimated which allows to disentangle the long run effects of these trading externalities from those of internal economies of scale and of aggregate industry-level economies. The results obtained—based on a cointegrated system of non-linear-error-correction equations—confirm the hypothesis that the trading externality matters. Moreover, our findings point out that the emphasis generally posited both on internal and external economies of scale is not justified.
