制度创新与民营企业竞争力

制度是决定民营企业竞争力的重要因素。从新制度经济学角度看，制约民营企业竞争力的制度问题主要存在于交易费用、产权、制度构成、制度变迁、制度供求均衡等方面。制度创新能促进民营企业竞争力的提高，途径是：清晰企业产权、实行股权多元化、强化资本运作、完善公司法人治理结构、保护知识产权、放松产业准入限制等。

The Nested PIGLOG Model: An Application to U.S. Food Demand

A new demand system is introduced, the Nested PIGLOG model, nesting thirteen other demand systems including five that are also new. This new model and its nested special cases are applied to models of U.S. food demand that include food-at-home (FAH), food-away-from-home (FAFH), and alcoholic beverages. Although nested tests and out-of-sample forecasting performance favor generalizing models to a certain degree, statistically insignificant improvements to in-sample-fit and even poorer out-of-sample forecast accuracy undermine further generalizations. Based on a subset of preferred models, FAFH is found to be price and income elastic compared to FAH which is price and income inelastic.     

Price Rigidity and the Selection of the Exchange Rate Regime

We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the best monetary arrangement for the pegger. JEL Classification Numbers: E32, E52, F33, F42     

物流标准化对物流企业竞争力提升的作用分析

物流标准化问题已成为制约我国物流发展的瓶颈问题之一,而物流产业的发展需要产业内的公司的竞争力的持续提升,由产业组织经济学对企业竞争力的解释框架,可得出企业竞争力的市场表现主要有成本优势、差异优势和领先优势三个方面。本文将分别从这三个方面分析物流标准化对物流企业竞争力提升的作用。     

Operational Research and the environment

The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems.
