What drives organic food consumption in Lebanon?

To increase the sparse knowledge about what drives organic food consumers in developing markets, Lebanese consumers' reasons and motives for buying organic food are studied in the framework of means‐end chain theory. A sample of N = 180 Lebanese consumers was interviewed in several retail outlets using a hard laddering questionnaire. The data were subjected to frequency analysis, cluster analysis, and structural equation modelling. Hierarchal value maps constructed from the laddering interviews revealed that “quality of life,” “pleasure,” and “peace of mind” are the main values driving organic food consumption in Lebanon. Frequent organic consumers displayed higher concern for their family's health and for the environment, whereas occasional organic consumers cared more about their own pleasure and were more likely to perceive organic food as a traditional and nostalgic product. Structural equation modelling revealed that “care for nature” and “care for children's health” significantly affect consumers' (self‐reported) purchasing behaviour. The found means‐end chains are a useful basis for marketing campaigns for organic food products in the Lebanese market. One focus of marketing campaigns should be raising consumers' awareness on the environmental benefits of organic production and the fact that it does not allow the use of harmful chemical products.     

基于供给侧的贵州省生态农业绩效评价

［目的］随着供给侧改革的推进,贵州省生态农业发展迅速,为了实现生态农业的可持续发展,对生态农业发展效益进行客观地评价具有重要意义。［方法］文章以贵州省9个市（州）的生态农业数据为研究对象,构建贵州省生态农业绩效指标评价体系,利用因子分析法对贵州省9个市（州）的生态农业数据进行主成分分析,计算每个地区的综合得分情况。［结果］通过对贵州省生态农业绩效构建评价指标体系,从社会投入与产出、耕地投入与产出两个方面来进行评价。各市（州）综合得分结果表明遵义市和毕节市的得分最高,分别为4456 595万和4388 418万; 六盘水市和贵阳市的得分比较低,分别为1572 071万和1621 515万。［结论］贵州省各市（州）生态农业发展存在较大的地区差异性,遵义市和毕节市的生态农业效益最好,安顺市、六盘水市、贵阳市的生态农业建设相对较弱。因此,贵州省应该加强政策引导、利用先进技术、加大生态农业的投入,从各方面促进生态农业的可持续发展。     

人身险需求对物价波动的非对称响应——基于中国2000-2010年季度数据的实证研究

基于中国人身险市场2000-2010年季度数据的实证分析表明,人身险需求增长率对于物价波动的反应是非对称的。首先与物价明显上涨的情况相比较,人身险需求对物价明显下跌的反应更加强烈。其次,适当提高名义利率的通货膨胀弹性将有助于人身险市场的快速发展。第三,目前温和的通货膨胀可以促进人身险需求的增长,人身险企业应该抓住扩大内需的有利时机。第四,由于市场需求模式在门限值附近出现较大改变而有可能冲击人身险行业,所以当通货膨胀率接近门限值时,人身险行业应该及时地调整营销策略。     

衡水市农户土地资源转出意愿的影响因素与行政干预

[目的]通过了解河北省衡水市农户土地转出的意愿状况,分析影响农户土地资源转出意愿的关键因素,并制定正确的战略决策,为构建农地适度规模化经营奠定理论基础,促进衡水市农民的现代化发展。[方法]文章结合调研情况,对样本区农户土地使用权流转行为进行了统计描述和分析研究,并运用Logistic模型对农户土地使用权转出意愿的影响因素进行了分析,找到了影响衡水市土地流转的关键性因素。[结果]研究表明,户主年龄、从事职业和文化程度、农户家庭非农收入以及农户家庭兼业人数等与农户土地转出意愿呈显著正相关关系,显著性数值分别为0. 018、0. 000、0. 010、0. 000、0. 028,而农户家庭农用机械数量则与农户土地转出意愿呈显著负相关关系,显著性数值为0. 033。此外农户社会保障程度和农户对政府土地流转的相关政策了解程度等因素也影响着农户土地流转的意愿。[结论]影响农户土地转出意愿的显著性因素包括家庭非农收入、户主年龄和职业;另外,户主的年龄、职业、文化程度、非农收入、家庭兼业人数和农用机械数量均是影响农户土地转出意愿的重要内容。     

Waves and Determinants in Mergers and Acquisitions: The Case of Latin America

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect.
