交易成本对易货经济的影响——瓦尔拉斯均衡“不成立”的一种情形

本文首先用一种新的解析几何方法在易货经济 (即两种商品的纯交换经济 )条件下的一般均衡框架下揭示了价格与消费者的马歇尔需求之间的函数关系。在此基础上 ,由个人承担的交易成本被直接置入。然后 ,本文证明 :如果交易成本的固定项不为零 ,供、求函数将不连续 ;如果同时有非无穷小比例的人口进行同步化决策 ,那么瓦尔拉斯均衡将会被破坏

From cultivation to culture: Wheat farming and sex selection in China

Sex selection has been linked to son preference and discrimination against girls in many Asian countries. In this study, we shed light on the shaping role of rice–wheat cropping system to the subsequent gender inequality in China. Using an individual-level dataset compiled from a national scale survey and an archaeology publication, we show regional differences in gender inequality across China: parents show strong gender discrimination against girls in wheat regions. And 15.2 percentage points more parents from wheat regions engage in successful sex selection than those from non-wheat regions. The mechanism analysis reveals that women empowerment matters.

A Conjoint/Logit Analysis of Consumers’ Responses to Genetically Modified Tofu in Taiwan

We use data collected from a consumer survey of face‐to‐face interviews to determine consumer demand for genetically modified (GM) tofu attributes in Taiwan. Conjoint analysis using logit models reveals that, on average, brand is the most important attribute in terms of influence on consumers’ preferences, followed by price, with GM content having the least influence. However, the analysis also reveals three distinct market segments for tofu. Apart from the largest segment (which reflects the average lack of concern about GM food), the remaining two segments are split according to their preference or antipathy towards GM tofu. This result suggests that GM labelling is helpful to Taiwanese tofu consumers.     

西安休闲农业可持续发展能力评价与分析

休闲农业在社会主义新农村建设中起到关键作用,对自然地理环境优势明显、农业资源丰富、交通条件设施完备的西安来说,近年休闲农业旅游在旅游业的比重逐年提高,游客接待数量与相关旅游收入也达到新的高度。文章从经济基础、产业基础、社会基础、资源基础、产业与社会持续性、产业与生态持续性、基础设施条件、经营与管理能力持续性等8个方面共选择28个评价指标,构建了休闲农业可持续发展能力评价指标体系。以西安休闲农业为研究对象,利用2007~2013年相关统计数据,在得出指标评定系数与指标轻重的基础上,按照Z_t=∑W_i×Y_(it),对西安休闲农业可持续发展能力进行综合评价。通过数据分析,总结出西安休闲农业可持续发展能力体现以下特征:影响可持续发展的因素较多,休闲农业开展地区居民旅游收入提高,交通条件改善,网络通讯水平可持续良好,劳动力数量增长也较为缓慢,生活垃圾、生活用水处理与清洁程度还存在不足,当地居民文化水平提高程度可持续性增长缓慢。最后依据评价结果,对西安休闲农业的可持续发展提出了4项措施,即提高休闲农业管理水平,合理开发休闲农业资源,注重地区农业文化特征的表现及建立农业科技体系。     

Incentives to managers or participation of farmers in China's irrigation systems: which matters most for water savings,farmer income,and poverty?

The overall goal of our article is to better understand which matters for water savings, farmer income and poverty in China's irrigation systems: incentives to managers or participation of farmers. To pursue this goal, the article has three objectives. First, we track the evolution of water management reform, examining the practice of providing incentives to managers, and increasing the participation of farmers. Second, we identify the impact of water management reform on crop water use. Specifically, we want to measure whether or not incentives to managers and farmer participation in water management institutions affect the performance of the irrigation system. Because we also are interested in the potential results of water management reform, the article explores how changes in incentives and farmer participation affect farmer income and poverty. Based on a random sample of 51 villages and 189 farmers in four large irrigation districts in Ningxia and Henan provinces, both in China's Yellow River Basin, our results show that the two major forms of water management reform, water users' associations (WUAs) and contracting, have begun to systematically replace traditional forms of collective management. Our analysis demonstrates, however, that it is not the nominal implementation of the reform that matters, but rather it is the creation of new management institutions that offer water managers monetary incentives that lead to water savings. In contrast to the original design of China's reform policies, participation of farmers has not played a role in saving water. Importantly, given China's concerns about national food production and poverty alleviation, the reductions in water, at least in our sample sites, do not lead to reductions in income and do not increase the incidence of poverty.
