Capturing structural changes in French meat and fish demand over the period 1991 2002

A time-varying coefficient demand system, the Markov switchingalmost ideal demand model, is proposed to shed new light onchange over time in the structure of French meat and fish demand.The main feature of this model is that the switching mechanismfrom one structure of demand to the other is controlled by anunobserved variable that follows a Markov chain. Our model accuratelycaptures the two Bovine Spongiform Encephalopathy (BSE) crisesof recent years. We estimate that the 1996 BSE crisis lastedalmost three years, whereas the second BSE crisis for just lastedfive 4-week periods.     

Exploring costs and benefits of compliance with HACCP regulation in the European meat and dairy sectors

A Hazard Analysis and Critical Control Point (HACCP) Program was introduced as a mandatory measure in the EU in the 1990s. Despite its impact on the food industry, only limited literature addresses the issue of cost and benefits of HACCP at the firm level in Europe. This paper illustrates the results of a pilot study on case studies in Italy, UK and The Netherlands, providing a first assessment of the order of magnitude of costs of compliance and a qualitative illustration of the main benefits perceived by producers.

食品安全是关乎人们健康的重大民生问题,由于近年来我国食品安全问题频发,食品安全监督抽检工作开始受到社会各界的关注和重视,该工作也是防范食品安全问题和排查食品安全风险的重要手段。本文针对2020—2021年咸阳市3个县的食用农产品抽检工作展开分析,并提出了提高检测机构能力、完善监管机制、创新监管模式的建议,旨在能够提高基层食品监管工作的质量。     

家庭生命周期、风险偏好对农户规模经营意愿的影响——基于江苏北部两县市的调查数据

研究目的：探索家庭生命周期对农户规模经营意愿的影响,特别是风险偏好在其中发挥的中介作用,以期为土地适度规模经营政策的完善提供参考。研究方法：采用中介效应检验流程,使用普通最小二乘法和Ologit/Logit模型。研究结果：（1）家庭生命周期对农户规模经营意愿具有显著的直接影响,不同家庭生命周期阶段下的农户,其规模经营意愿存在差异。（2）家庭生命周期会通过风险偏好间接影响农户规模经营意愿,空巢夫妇家庭的风险偏好程度最低,农户规模经营意愿最弱,成长中核心家庭的风险偏好程度最高,农户规模经营意愿最强。（3）家庭的农业专有资产积累越多、土地产权越安全、灌溉条件越好,农户规模经营意愿越强。研究结论：为引导农户规模经营意愿,促进土地流转和规模经营,政府政策的制定应考虑不同家庭生命周期阶段具有的劳动力和资金资本规律;积极发展土地流转市场,促进农户规模经营意愿的实现;建立正规的农业避险机制;促进农户农业专有资产的积累、保障和提高土地产权安全、改善土地灌溉设施条件。
