基于Stackelberg模型的出口补贴政策对经济的影响分析

出口补贴政策一直是各国政府重点研究的战略性贸易政策之一。本文在Stackelberg寡头垄断模型的基础上，分析了当两国企业共同竞争海外市场时，追随者企业所在国的补贴政策对各国经济活动的影响效果。结果显示，补贴政策会增加本国企业的产量，提高本国企业的利润和净福利，甚至会在产品价格下降的情况下提高本国总体福利水平。     

B2C交易模式下的闭环供应链模型研究

整合传统的正向供应链与退货回收的逆向供应链，在集中式决策和分散式决策条件下对模型进行求解，计算出不同决策条件下新产品和再制品的最优零售价、闭环供应链或者制造商和电子商务企业的最优利润。在整个模型的求解和分析过程中，探究不同决策条件下退货回收价、退货量、退货回购价等对最优零售价或者最优批发价的影响，并将集中式决策条件下最优零售价和闭环供应链总利润与分散式决策条件下相应的最优零售价和制造商与电子商务企业的最优利润之和进行比较，研究发现集中式决策的利润优于分散式决策。     

巴泽尔产权界定的逻辑思路

巴泽尔重新厘清了产权、交易成本和最大化概念,提出或阐明了资产属性、变化性、公共领域和共同财产、法律权利和经济权利等独特的概念,并将资产属性化作为产权界定的逻辑起点。巴泽尔产权界定的逻辑运用非价格机制的独特理路,注重个人的努力和边际调整,为推进现代产权理论发展做出了贡献。但巴泽尔产权分析中的一些概念,如变化性、产权分割、限制等,尚未受到足够的重视,而巴泽尔产权理论难以数理化的特点限制了它的推广。     

管理输出模式初探——大型旅行社选择的新型赢利模式

管理输出模式作为一种赢利模式,以其内在的赢利机制,在很多行业都获得了成功,但在我国旅行社行业中却少有使用。旅行社的行业特点,以及我国大型旅行社所面临的经济体制条件、市场条件和主体条件,决定了我国旅行社行业实施管理输出模式具有一定的可行性。实施管理输出模式是一个系统的工作,我国的大型旅行社在实施的过程中应当采取相应的策略。     

论合作思想对经济学的影响

合作分为隶属合作、非隶属合作、隶属与非隶属混合合作三种形式;合作的进化推动社会的发展;建立在个人利益最大化基础上的经济学理论遇到了不少矛盾,应在以共同利益最大化的合作思想基础上重构经济学体系。     

一种基于EM算法的MIMO-OFDM系统信道估计技术

从提高多输入多输出正交频分复用（MIMO—OFDM）系统频谱利用率的目的出发，提出了一种改进型的基于EM（Expectation Maximization）算法的信道估计技术。仿真结果表明，改进后的算法可以显著提高频谱利用率，同时保持原算法的精度。     

An empirical test of the rent-shifting hypothesis: the case of state trading enterprises

A central result in the theoretical literature on strategic trade is the ‘rent-shifting hypothesis’, the idea that government’s can employ trade policy as a precommitment device to transfer profit from foreign to domestic firms. To our knowledge, however, the rent-shifting hypothesis remains untested empirically. This paper constructs a theory-based empirical test of rent-shifting behavior that relies on observations of government precommitment variables employed through State Trading Enterprises (STEs). The analysis applies data on the delayed producer payment structure of the Canadian Wheat Board (CWB) and examines its merits as a rent-shifting mechanism in the international durum market. The model fails to reject the hypothesis that the CWB utilizes a pre-commitment mechanism in the international durum market and several nonparametric tests confirm that the observed transfer payments set by the CWB are consistent with rent-shifting behavior in the 1972-95 pre-WTO period.     

Specification and estimation of nonstandard profit functions

This paper critically examines appropriateness of the nonstandard profit function (NSPF) as a tool for measuring profit efficiency. We show that there are some fundamental problems with the NSPF approach, the way it is currently specified and estimated. This is true irrespective of whether technical inefficiency is included or not. Instead of estimating profit efficiency directly from the NSPF, we suggest alternative specifications and recommend using the cost function approach and deriving profit efficiency therefrom. Data from US banks are used to estimate the cost function and the NSPF. Results from alternative specifications are then compared and analyzed.

Optimal pricing, production rate, and quality under learning effects

This study investigates the marketing and production problem for a monopolist firm where price, quality and production rate are simultaneous dynamic decision variables under the condition of a dynamic demand that depends on price, quality and cumulative sales. The formulated continuous profit maximization model follows the steps for dynamic optimization to derive optimal price, quality and production policies, wherein a unit production cost that decreases with cumulative production reflects the cost learning effect. Through the differentiable multiplicatively separable demand function, this study analyzes optimal trajectories for determining price, quality, and production rate. The results specify several optimal policies and policy makers would gain insight into the consequence of their decisions that otherwise might have been obscured by sub-optimal analysis.
