The Problem of Factor Price Equalization

In this paper we propose a new boundary condition to assure factor price equalization. The simple and applicable boundary condition guaranteeing the existence of a unique solution to the equation C ( w ) = p , where p is a given vector of output prices and C a vector of unit-cost functions. The argument is based on mapping degree theory in differential topology.

Factor Endowment,the Choice of Technology,and the Volume of Trade

Abstract

This paper studies impacts of factor endowment on international trade in a general equilibrium model in which firms choose their technologies endogenously. Although countries only differ in factor endowment ex ante, countries may also differ in their chosen technologies. If industries choose different capital-labor intensities in equilibrium, the Heckscher–Ohlin theorem, factor price equalization theorem, the Rybczynski theorem, and the Stolper–Samuelson theorem hold. If industries choose the same capital-labor intensity in equilibrium, the volume of trade is zero. None of the four theorems applies.     

均衡价格--动态市场价格的形成与变化趋势

本介绍了用来模拟动态市场价格的微分方程模型，此模型反映了价格对需求与供给的影响，而需求与供给反过来又影响价格确定的过程，并说明了均衡价格是市场价格的最终变化趋势，并用蛛网理论对产量和价格的波动进行了分析。     

贸易成本、要素流动与区域经济差异

本世纪以来,中国交通基础设施不断优化、物流业的迅猛发展以及国内市场化的不断加深对中国区域间要素流动、产业转移及区域经济差异的影响,成为具有重要理论与现实意义的问题。本文通过构建包含贸易成本的两地区-两部门新经济地理模型来研究这一问题,并在合理的参数条件下进行数值模拟。研究发现贸易成本的降低阻碍了劳动力、资本与可贸易产业从发达地区向欠发达地区的流动和转移,加大了地区间经济差异,从而为"迁移谜题"提供了新的解释角度。根据理论研究的结果,本文提出相关的政策建议。     

当前房地产价格走势与宏观调控策略选择

房地产价格形成的基础具有其他商品所没有的特殊性。面对房地产价格快速上涨的态势，为了既不伤害房地产业的健康发展，又能有效满足广大城市居民对住宅的需求，应当把宏观调控的切入点放在直接调近代房地产供求。稳定房地产价格的关键在于实现有效供求平衡。     

煤炭价格指数的理论设计与应用研究

论证了在当前煤炭价格风险凸现的情况下,推出煤炭价格指数是运用煤炭期货、期权及互换等金融衍生工具的重要前提,并借鉴国外煤炭价格指数应用与研究的经验,提出我国煤炭价格指数的基本体系及编制的基本原则和基本方法.     

不完全信息静态博弈视角下的三度价格歧视分析研究

本文针对三度价格歧视存在信息不对称的问题,讨论了两个寡头垄断企业在成本信息不对称的情况下,在两个细分市场实施价格歧视的产量决策问题.将成本函数分为三种、两种及一种可选成本(完全信息)3类情况,通过海萨尼转换,根据成本甄别系数的不同取值范围,得出了两个寡头垄断企业相互制约下的均衡产量、均衡价格、均衡利润及相互关系.研究结果表明:成本甄别系数越小,成本信息劣势企业的均衡产量越高,均衡状态下的总利润也越高;当寡头垄断企业1采用较高成本时,企业1会更加倾向于隐藏自身成本,他在具有信息优势的同时还具有成本劣势;而当寡头垄断企业1采用低成本时,则不会隐藏自己的信息而更倾向通过信号传递,把低成本信息的优势传递出去,以使寡头垄断企业2按完全信息决策产量等结论.本文的研究结果将为信息不对称下的歧视定价提供理论依据.     

中国区域贸易增长与环境污染的因子聚类分析

随着中国经济与贸易的快速增长，传统的区域划分在研究贸易与环境政策问题时的局限性愈发凸显。运用因子方法对1992～2005年中国各省市、自治区近十几年来经济、贸易增长与环境污染的数据进行分析，可为贸易与环境污染的区域研究提供新的参考依据。     

国际资本流动对房地产价格的影响——基于我国的实证检验(1998-2006年)

本文在考虑通货膨胀的条件下,利用我国1998-2006年的实际利用外资和房地产价格的季度数据建立误差纠正模型(ECM),使用Granger因果检验方法对我国的房地产价格和国际资本流动的关系进行实证检验.得出结论,短期而言,房地产价格上涨吸引了外资的流入;长期来说,外资的流入对我国的住房价格上涨产生了影响.在现阶段控制外资过度流入房地产市场,有利于保持我国房地产价格的稳定.     

Commercial Property Price Indices and Indicators: Review and Discussion of Issues Raised in the CPPI Statistical Report of Eurostat (2017)

Commercial property price indices (CPPIs) are needed to monitor financial stability, guide investment decisions by firms, and improve national accounts. Due to a lack of suitable data, however, reliable CPPIs are often hard to construct. Here we survey the current state of the CPPI literature and assess the contribution of the recently published Eurostat CPPI report.

The Real Exchange Rate and the Structural Transformation(s) of China and the U.S.

From 1989 to 2010, the RMB–dollar real exchange rate depreciated, despite China's rapid income growth relative to the US. We develop a macroeconomic-trade model of the very long-run equilibrium RMB-dollar real exchange rate. We show that this long-run depreciation of the RMB-dollar real exchange rate can be justified by our model, if we note that Chinese agriculture has relatively low productivity and that agriculture is tradeable. Relative to our equilibrium benchmark, the current real RMB-dollar rate is, if anything, over appreciated.     

The Financial Crisis and the Death (or Hegemony) of Development Economics

Development economics was the study of how to create the plumbing that would allow developing economies to become developed. The financial crisis leads us to question whether industrialized countries have the plumbing problem solved and thus leads us to question whether we need a development economics that is separate from macroeconomics. Indeed, it even leads us to question whether development economics should take as its goal the creation of the institutional plumbing that industrialized countries currently have. The consequence will be a blending of concerns that have been central in developing economies with the standard macro models. The blending can be seen as either the death of development economics or the hegemony of development economics.     

Bond Price and Impulse Response Function for the Balduzzi, Das, Foresi and Sundaram (1996) Model

In this paper, we analyse the Affine Term Structure Model (ATSM) proposed by Balduzzi, Das, Foresi and Sundaram (BDFS, 1996) and provide the closed-form expression of the bond price. In addition, we extend the notion of Impulse Response Function to the class of ATSM. We show that it is closely related to the duration measure, and we compute it explicitly in the BDFS model.
