The theorems of international trade with joint production

This paper analyzes the implications of joint production for the four basic results of the factor-endowments theory of international trade. The nature of the relationship between commodity prices and factor rewards is first elucidated in detail. It is then shown that, in sharp contrast to prevalent opinion, there is in fact a strong presumption that the basic theorems will continue to hold in essence. The paper then considers applications and extensions of the analysis to higher dimensions.     

中国农村劳动力外流对留守家庭成员时间分配的影响

农村劳动力的大量外流,对于家庭留守成员的时间分配会产生什么样的影响?运用1997-2006年中国营养与健康调查数据,本文研究了成年人出外打工对妻子、儿童和老年人家务和农业劳动时间利用的影响.研究发现:丈夫出外打工显著地增加了妻子的农业劳动时间;父亲出外打工对于儿童家务劳动有显著的增加作用,并且对女孩的影响比男孩大;有成员出外打工的家庭,老年男性和女性在农业劳动中的时间投入都显著增加,家务劳动方面,老年女性受到的影响更大一些.     

高尔夫球场草屑作为堆肥原料的研究

主要对高尔夫球场3～11月间的草屑作为堆肥原料进行了初步研究。结果表明,不同月份修剪下的草屑量不同,以5月份球道的平均修剪量最高,鲜重可达124.6g/m2。高尔夫球场修剪下来的草屑含有大量的营养元素;施用农药后,修剪下来的草屑检测到农药的残留;高尔夫球场的草屑C/N值一般在10左右。     

所有制结构变动与居民收入差距:研究综述

改革开放以来,我国经济赢得了持续快速发展。这主要得益于:以资本和劳动为代表的物质要素供给不断增加;以所有制改革为核心的经济体制改革有效推动了经济技术效率的提高。但是,在所有制结构转换推动国内经济发展和居民收入水平改善的过程中,也对经济公平带来了严重的挑战,这突出表现在居民收入差距的逐渐扩大。本文重点考察了近年来国内外在所有制结构变动与居民收入差距研究方面的有关成果,并在综述这些成果的同时,研究了所有制结构变迁引起经济增长,经济增长与收入差距的交互关系以及所有制结构变动如何传导至收入差距。     

西藏非物质文化遗产法律保护的实证分析

《保护非物质文化遗产公约》的通过是传统文化由传统方法保护转变为特殊权利方法保护的例证,也为西藏传统文化的保护提供了全新的范式。《非物质文化遗产保护法》无疑将成为西藏非物质文化遗产保护最基本的国内法依据,而包括宪法、民族区域自治法在内的规范性法律文件构成保护西藏非物质文化遗产的其他国内法渊源。当下,对于西藏非物质文化遗产的保护,我们在欢庆《非物质文化遗产保护法》出台的同时,应积极推进地方立法的工作。     

中国期货市场的发展历程与背景分析

期货市场既不能超越经济发展的阶段,也不能长时间滞后于经济的发展。中国期货市场的发展是市场经济发展的必然要求,和经济体制的变革、演变密切相关。本文力图从中国期货市场发展的历史角度,解释中国期货市场变迁的经济背景。     

流动人口非正规就业空间竞争:基于上海若干样点的调查

流动人口占有市场空间是个体或利益集团相互竞争、实现市场空间均衡的结果。本文以上海流动人口为研究对象,以非正规就业空间为研究视角,通过分析四类不同性质的非正规就业群体,阐明了流动人口就业空间竞争的基本原理与基本过程,并得出流动人口空间竞争的原动力来源于获利的可能性,空间竞争的过程是空间占有的过程,也是利益均衡的过程。     

Optimal growth and impatience: A phase diagram analysis

When the time preference exhibits decreasing marginal impatience, the rate at which the discount function decreases plays a central role in the stability analysis. This paper shows that if the discount function is strictly decreasing, strictly convex and has a uniform bound on its first derivative, then the continuous-time, one-sector optimal growth problem has a unique steady state that exhibits the saddle-point property. Moreover, the phase diagram analysis is geometrically similar to the case of a constant discount rate. The proposed bounded slope assumption is inspired by and in direct contrast with Magill and Nishimura's "division of countries" example.     

The political economy of tariff protection in China: evidence from the WTO accession

We analyze China's tariff rates at WTO accession using a political economy approach. A model drawing on Branstetter and Feenstra ( 2002 ) is used to derive an optimal tariff rate for each industry. The model predicts that a government would set a high tariff rate if an industry is of large state‐owned enterprise (SOE) share, multinational share, or small foreign import share. From the model we reveal the Chinese government's preference towards different interest groups under the binding tariff constraint from the WTO commitments. The estimated structural parameters imply that the political weights on both the SOE profits and consumer income diminish with the economic opening. More important, the government still favours SOEs over consumer income. Our findings are consistent with the special features of China's economy.     

Trade liberalization,wages, and specialization in China

This paper studies the evolution of regional specialization in China in response to trade liberalization. Using a panel of Chinese export data at the detailed commodity level over the period of 1988–2006, we show that China’s regional specialization follows a U-shaped pattern: both the interior and coastal regions diversify from 1988 to 1994 but specialize during the later reform period of 1994–2006. A theory of tariff reductions is proposed by constructing the Dornbusch–Fischer–Samuelson (1977) continuum of goods Ricardian model in a setup of two countries and three regions. The U-shaped pattern of specialization can be obtained from foreign tariff reductions followed by Chinese tariff reductions. This finding is supported by simulations, US–China trade policy review, and the pattern of China’s coast–inland wage ratio.
