What drives stock market integration? An analysis using agribusiness stocks

This article explores the drivers of regional stock market integration with a focus on the agribusiness sector across relevant regional trade blocs around the world. We implement panel cointegration models to analyze the stock indices of agribusiness firms in the Southern Common Market (MERCOSUR), European Union (EU), Asia‐Pacific Economic Cooperation (APEC), and North American Free Trade Agreement (NAFTA). Based on the literature on market integration and stock return pricing, we identify nine possible determinants of stock market integration, which we separate into three categories: individual market performance, macroeconomic conditions, and agricultural trade. In our analysis, we account for agriculture‐specific factors to control for possible structural shifts in financial markets regimes by including the two main commodity price bubbles during last 20 years. Our results show that most of the variables included in our categories have been important factors in promoting regional stock market integration. Moreover, integration among regional stock markets was strengthened by the implementation of trade agreements. This effect is stronger in trade blocs with fewer members, such as NAFTA and MERCOSUR, compared with larger and more heterogeneous blocs, such as the EU and APEC.     

Macroeconomic Policy Design in the European Monetary Union: A Numerical Game Approach

Optimal economic reactions of European policy-makers on exogenous shocks are determined by simulating a global macroeconomic model under different institutional arrangements. In particular, it is investigated whether discretionary or rule-based policies and whether non-cooperative or cooperative policies for Europe result in a better performance as measured by intertemporal objective functions. The results show that the answers to these questions depend strongly on the nature of the shock to which European economies are exposed. For a negative supply shock, rule-based policies dominate, whereas for a negative demand shock, cooperative fiscal policy-making within the European Monetary Union gives the best results.     

地勘单位探采一体化的政策研究

地勘单位探采一体化是近年来学术界持续升温的热点话题。一些业内人士认为,地勘行业、地勘单位探采一体化似乎天经地义,理所当然,因为地勘单位是距离采矿最近的行业,采矿是地质勘查找矿的自然甚至必然的延伸。实际上,我们必须找准角度,分析国家和地方政府为什么没有明确给予地勘单位探采一体化政策,通过政策和地勘单位性质方面的研究,尽可能找出和提前应对各方面的困难和问题,合理调配和优化企业化经营的要素,做好企业化改制和探采一体化等各方面的准备。     

轮作休耕及其补偿的法律意蕴、法理证成及入法进路

研究目的：从认识事物一般规律的逻辑出发,解读轮作休耕及其补偿的法律意蕴,寻找法理证成依据,构造自洽法权秩序。研究方法：法经济学研究方法、法学价值论研究方法。研究结果：社会法本位的兴起使得私人权益受到公共利益考量的限制,财产权社会义务要求耕地使用权作自我限缩,而“公平优先、效率跟进”思路和“权利义务对等”原则成为给付轮作休耕补偿的学理依据,轮作休耕及其补偿权利在法本质上具有土地行政规划与土地发展权的性质。研究结论：轮作休耕的深化实践依赖“有法可依”的规则话语体系。通过引进公共地役权续造既有役权,允许公法适度介入私法以协调轮作休耕中资源利用与环境保护的矛盾,完善中国的环境法律体系。     

现代农牧业纵横一体化综合效益及创新模式  ———以北方农牧交错带为例

易地扶贫搬迁安置方式对搬迁农户社会融入的影响研究

目的 农户搬迁后在安置地的融入和发展是决定易地扶贫搬迁工程成功与否的关键,分析安置方式对搬迁农户社会融入的影响,有利于为实现农户更好融入新环境提供对策建议。方法 文章从社会融入角度出发,通过构建搬迁农户社会融入指标体系,利用8省16县969户的搬迁农户样本和多层模型分析技术,实证检验了安置方式对搬迁农户社会融入的影响及其作用机制。结果 与村内安置相比,外村安置、乡镇安置和县城安置对搬迁农户的社会融入产生了显著负向影响,且影响程度依次增大,具体表现为对搬迁农户经济融入、社会交往融入以及心理融入的影响。机制分析得出：安置方式通过影响农户的生计方式和生活方式影响其经济融入,通过影响农户的旧关系网络和新关系网络的建立影响其社会交往融入,通过影响农户对新环境的适应程度影响其心理融入。结论 要根据实际情况精准施策开展帮扶,满足搬迁农户的安置需求,促进农户融入新环境。     

World market integration for export and food crops in developing countries: a case study for Mali and Nicaragua

Using a generalized error correction model, this article measures and compares market integration for export cash crops versus imported food crops for Mali and Nicaragua, and computes transmission elasticities between changes in the goods’ border and domestic prices. Both Mali and Nicaragua obtain the bulk of their export revenue from a particular agricultural commodity—cotton for Mali and coffee for Nicaragua—and both import the same key staple food of rice. To reap the economic gains from this trade specialization, the two countries’ agriculture must be well‐integrated into world markets. The two countries present an important policy contrast that affects their degree of world market integration and price transmission. In Mali, a parastatal enterprise controls its cotton industry, while Nicaragua has less state direction over agriculture. Reflecting this difference, the results show that for both its main export and import commodity, Nicaragua is more integrated into world markets and has higher price transmission than Mali. The results for Nicaragua also show much higher integration and price transmission for its main agricultural export (coffee) than its major import (rice).
