This paper uses a randomized survey instrument to study the impact of African Swine Fever (ASF) information on Chinese consumers’ preference for pork attributes and purchases during the recent peak of the ASF pandemic in 2019. We study consumers’ preference for pork attributes including brand, meat texture and taste, quality safety assurance, and traceability under different information treatments. Results show that the willingness to pay (WTP) for quality safety assurance is the highest, followed by brands and traceability systems, and the WTP is lowest for good taste. We show that providing detailed ASF information substantially changes consumer preference by altering the relative importance of pork attributes and price sensitivity, which enables consumers to focus more on safety-related attributes while paying less attention to price and taste attributes. Furthermore, we find that a higher belief in the future of ASF occurrence reduces the frequency of purchases marginally but does not significantly influence for amount per purchase and the total purchase amount.

本文使用随机调查工具研究了2019年非洲猪瘟疫情高峰期间,非洲猪瘟信息对中国消费者对猪肉属性和购买偏好的影响。我们研究了消费者在不同信息处理下对猪肉属性的偏好,包括品牌、肉质和味道、质量安全保证和可追溯性。结果表明,质量安全保障的支付意愿(WTP)最高,其次是品牌和可追溯系统,良好品味的支付意愿最低。我们发现,提供详细的ASF信息通过改变猪肉属性和价格敏感性的相对重要性,极大地改变了消费者的偏好,这使消费者能够更多地关注安全相关属性,而较少关注价格和口味属性。此外,我们发现,对未来ASF发生的更高信心略微降低了购买频率,但对每次购买的金额和总购买金额没有显著影响。

This article estimates the U.S. state-level soybean export forecast until December 2024 using a seasonal autoregressive integrated moving average (SARIMA) model. We utilize the newly developed exchange-rate equity market volatility (EMV-EX) to improve model fit and the Dirichlet process mixture model (DPMM) to control for unobserved heterogeneity. Using monthly data from January 2004 to December 2020, the study shows that soybean exports for states without ports are underestimated at the expense of states with ports. The EMV-EX has a positive effect on soybean exports. The forecasts reveal no expected changes in the trends for soybean exports until December 2024. This study's results are useful to make and to implement more informed policy decisions for risk-mitigating strategies such as the market-facilitation program.

本文使用季节性自回归综合移动平均(SARIMA)模型估计了2024年12月之前美国州级大豆出口预测。我们利用新开发的汇率股票市场波动率(EMV-EX)来改进模型拟合,并利用狄利克雷过程混合模型(DPMM)来控制未观察到的异质性。利用2004年1月至2020年12月的月度数据,该研究表明,没有港口的州的大豆出口被低估,而有港口的州则被低估。EMV-EX对大豆出口有积极影响。预测显示,在2024年12月之前,大豆出口趋势不会发生预期变化。这项研究的结果有助于制定和实施更明智的风险缓解策略政策决策,如市场便利化计划。

Chinese agriculture is experiencing a transition from smallholder farming to the emergence of commercial farms that are characterized by intensification and specialization in production, as well as commercialization and cooperation in management. It requires substantial capital to facilitate such a transition, but it is very difficult for farmers in China to access bank credit. One way that commercial farms have to overcome such handicap is by organizing themselves into cooperatives. To assess the effect of cooperatives on the credit accessibility of commercial farms, we have developed a theoretical model as well as an empirical study of commercial farms in Jiangsu Province based on data from a survey of 754 commercial farm owners. Instrumental variable (IV) methods and the Propensity Score Matching (PSM) method that control endogeneity problem are used in the analysis. The empirical results show that cooperatives have a significant positive impact on the credit access of commercial farms. Commercial farms participating in cooperatives may alleviated their credit constraints by about 17.3 percentage points and increase the average credit per capita by nearly 80,000 Yuan. Cooperatives improve the credit access of commercial farms by exerting strong market power and reputation effect based on its organizational advantages. A disaggregated analysis also reveals that small commercial farms tend to benefit more from cooperatives in improving credit access than large commercial farms.

中国农业正经历从小农农业向以生产集约化和专业化、管理商业化和合作化为特征的商业化农场的转变。这需要大量资金来促进这种转变,但中国农民很难获得银行信贷。商业农场必须克服这种障碍的一种方法是将自己组织成合作社。为了评估合作社对商业农场信贷可及性的影响,我们基于对754个商业农场所有者的调查数据,建立了一个理论模型,并对江苏省的商业农场进行了实证研究。分析中采用了工具变量法和倾向得分匹配法来控制内生性问题。实证结果表明,合作社对商业农场的信贷获取有显著的正向影响。参加合作社的商业农场的信贷约束可减轻约17.3个百分点,人均信贷可增加近8万元。合作社利用其组织优势,发挥强大的市场力量和声誉效应,改善了商业农场的信贷获取。一项分类分析还显示,小型商业农场往往比大型商业农场更能从合作社获得信贷。

This study estimates the willingness to pay (WTP) premiums for two novel traits available through genomic technologies in the dairy industry. Using a contingent valuation method to elicit WTP and the data from mail surveys collected from 486 Canadian dairy producers, we find a positive WTP premium for feed efficiency and a negative or zero WTP premium for reduced methane emissions. However, we observe positive valuations for reduced methane emissions if it is bundled with the feed efficiency trait. This finding suggests that the way private and public benefits of environmentally sustainable production alternatives are presented to livestock producers is critical, especially as the industry adapts to rising demand while holding an increasingly precarious position in environmental sustainability.

本研究估计了通过基因组技术在乳制品行业获得的两种新性状的支付意愿溢价。使用条件评估方法得出WTP,并从486家加拿大乳制品生产商收集邮件调查数据,我们发现饲料效率的WTP溢价为正,减少甲烷排放的WTP溢价为负或为零。然而,如果与饲料效率性状捆绑在一起,我们观察到减少甲烷排放的积极估值。这一发现表明,向畜牧业生产者展示环境可持续生产替代方案的私人和公共利益的方式至关重要,特别是在该行业适应不断增长的需求同时在环境可持续性方面的地位日益不稳定的情况下。

Business risk management (BRM) has been an important focus of Canadian agricultural policy in the New Millennium. Safety net payments received by farmers can alter their investment portfolio and lead to risk-balancing behavior in agriculture. Risk-balancing is an unintended consequence of the farm safety net program and has a direct implication for future growth and sustainability of farm business. Does risk-balancing exist in Ontario agriculture? This question is addressed in this paper using data for the hog sector in Ontario. While safety net programs were designed to address Business Risk (BR) for all farms, our empirical results indicate that CAIS/AgriStability payments reduced BR for small, medium, and large farms. The results from our fixed effect panel regression analysis demonstrate that there is a significant risk-balancing behavior among medium hog farms in Ontario. Our results also reveal that the presence of risk-balancing behavior in Ontario hog sector does not pose any problem for future growth of the hog sector or the long-term sustainability of the farm safety net program.

商业风险管理(BRM)一直是加拿大农业政策在新千年的一个重要焦点。农民收到的安全网付款可以改变他们的投资组合,并导致农业风险平衡行为。风险平衡是农场安全网计划的意外后果,对农场业务的未来增长和可持续性有直接影响。安大略农业存在风险平衡吗?本文使用安大略省生猪部门的数据来解决这个问题。虽然安全网计划旨在解决所有农场的商业风险(BR),但我们的实证结果表明,CAIS/AgriStability支付降低了小型、中型和大型农场的BR。我们的固定效应面板回归分析结果表明,安大略省中型养猪场存在显著的风险平衡行为。我们的研究结果还表明,安大略省生猪部门风险平衡行为的存在不会对生猪部门的未来增长或农场安全网计划的长期可持续性构成任何问题。

In emerging economies where small farms are the main source of food supply, it is costly for the government to monitor and control food safety and production impact on the environment. However, the online food market can potentially give farmers stronger incentives to supply safer and more eco-friendly products, as they can access a national market where consumers are interested in healthy food, and they can differentiate their products by providing production information using videos and pictures. This research uses the choice experiment method to elicit farmers’ preference for production practices and marketing channels in China where e-commerce and delivery businesses are fast-growing. Our main finding is that farmers perceive higher utility in selling safer and more eco-friendly products than conventional products when using e-commerce platforms, evidence of the online market's positive role in food safety enhancement. Our results also identify two types of farmers: traditional farmers and farmers open to the idea of online markets. Farmers who have higher education and live in villages with e-commerce service centers are more likely to be the latter.

在新兴经济体中,小农场是食品供应的主要来源,政府监督和控制食品安全和生产对环境的影响是昂贵的。然而,网上食品市场可能会给农民提供更安全、更环保的产品的更强动力,因为他们可以进入消费者对健康食品感兴趣的全国市场,他们可以通过使用视频和图片提供生产信息来区分他们的产品。本研究采用选择实验的方法,在电子商务和快递业务快速发展的中国,探究农民对生产方式和营销渠道的偏好。我们的主要发现是,在使用电子商务平台时,农民认为在销售更安全、更环保的产品方面比传统产品具有更高的效用,这证明了在线市场在提高食品安全方面的积极作用。我们的研究结果还确定了两种类型的农民:传统农民和对在线市场持开放态度的农民。受过高等教育且居住在有电子商务服务中心的村庄的农民更有可能是后者。

This article aims to understand the impact of board gender diversity (BGD) on the firm's deviation from efficient risk-taking (DERT) along with the mediating effect of sustainability reporting and the moderating effect of CEO overconfidence. The sample consists of 77 South Asian agri-food firms over the period 2010–2019. To account for endogeneity and other statistical biases, we use a system GMM approach. The results show that there is a non-monotonic relationship between BGD and DERT. Consistent with critical mass theory, we find that at least three women on board (WOB) are required to reduce the firm's DERT. The findings of the study also reveal that the overconfident CEO may restrict the female directors to achieve the firm's efficient risk-taking. The evidence further suggests that sustainability reporting quality (SRQ) does not mediate the link between BGD and a firm's DERT. The robustness tests are performed based on alternative risk proxy and the likelihood of financial distress. Our results theoretically support stakeholder, critical mass, and agency perspective that South Asian capital markets should enhance the representation of WOB to mitigate agency conflicts and to improve long-term firm sustainability.

本文旨在了解董事会性别多样性(BGD)对公司偏离有效风险承担(DERT)的影响,以及可持续发展报告的中介作用和CEO过度自信的调节作用。样本包括2010-2019年期间的77家南亚农业食品公司。为了解释内生性和其他统计偏差,我们使用系统GMM方法。结果表明,BGD与DERT之间存在非单调关系。与临界质量理论一致,我们发现至少需要三名女性董事(WOB)来降低公司的DERT。研究结果还表明,过度自信的CEO可能会限制女性董事实现公司的有效风险承担。证据进一步表明,可持续发展报告质量(SRQ)不调解BGD和公司的DERT之间的联系。鲁棒性测试是基于替代风险代理和财务困境的可能性。我们的研究结果在理论上支持了利益相关者、临界质量和代理的观点,即南亚资本市场应该提高WOB的代表性,以减轻代理冲突,提高企业的长期可持续性。

Willingness to pay for multiple dimensions of green open space: Applying a spatial hedonic approach 为多维绿色开放空间买单的意愿:应用空间享乐主义方法

To optimize land conservation strategies with limited resources, it is necessary to understand people's preferences and willingness to pay (WTP) for green open space. The hedonic pricing method (HPM) is widely used. However, the conventional HPM assumes no value spillovers between neighbouring properties. Here we adopt a spatial regression approach that allows us to relax the no-spillover assumption. Through an analysis of access to different types, intensity and developability of open green space on house prices in the City of Edmonton, Canada, we illustrate how spatial HPM can be used to quantify direct and spillover values of different dimensions of open green space. We find that WTP for open space has significant spillover effects, ignoring such spillovers would under-estimate the total value of open space protection and thus the socially optimal amount of land conservation. All else equal, people are willing to pay most for houses that are close to non-developable green open space and woodlands. The highest price premiums are for woodlands and non-developable green open space, followed by living near the University of Alberta farm. On the contrary, people need small compensation to live near large commercial farms. The results suggest a NIMBY attitude toward preservation of commercial agriculture.

为了在有限的资源条件下优化土地保护策略,有必要了解人们对绿色开放空间的偏好和支付意愿。享乐定价法(HPM)是一种应用广泛的定价方法。然而,传统的HPM假设相邻房产之间没有价值溢出。在这里,我们采用空间回归方法,允许我们放宽无溢出假设。通过分析加拿大埃德蒙顿市开放绿地的不同类型、强度和可发展性对房价的影响,我们说明了空间HPM如何用于量化不同维度开放绿地的直接价值和溢出价值。研究发现,开放空间WTP具有显著的溢出效应,忽视这种溢出效应将低估开放空间保护的总价值,从而低估社会最优的土地保护量。在其他条件相同的情况下,人们愿意为靠近不可开发的绿地和林地的房子支付最多的钱。房价溢价最高的是林地和不可开发的绿色开放空间,其次是阿尔伯塔大学农场附近的住宅。相反,人们需要小额补偿才能住在大型商业农场附近。结果表明,人们对保护商业农业持邻避态度。

All else equal, people are willing to pay most for houses that are close to non-developable green open space and woodlands. The highest price premiums are for woodlands and non-developable green open space, followed by living near the University of Alberta farm. On the contrary, people need small compensation to live near large commercial farms. The results suggest a NIMBY attitude toward preservation of commercial agriculture.</p>","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"70 3","pages":"179-201"},"PeriodicalIF":9.0,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84873346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of impacts of inflation on the distribution of household consumption expenditures 通货膨胀对居民消费支出分配的影响分析

As a consequence of the COVID-19 pandemic of early 2020, production in the United States, as in much of the world, largely came to a standstill. Unemployment in the United States quickly rose from 3.5% in February to 13.2% in May, quarter-to-quarter GDP fell 7.8%, and substantial transfers were enacted to maintain household income. The resulting mismatch between aggregate supply and demand not surprisingly ignited an inflation that by early 2022 had reached a year-over-year 40-year high. The purpose of the present communication is to utilize a framework developed from data embodied in surveys of households’ consumer expenditures to analyze impacts of this inflation on separate categories of expenditure. The engine for the analysis, whose construction is described in detail by Taylor (2013, is a matrix of “intra-budget” coefficients that represent the direct relationships amongst different categories of expenditure in households’ budgets. The elements of this matrix are constructed from the information in 58 quarters of data (2006 through 2019) from the ongoing BLS Survey of Consumer Expenditure to analyze effects and impacts on 16 categories of US household consumption expenditure of the 2021–2022 inflation. Principal findings include: expenditures for housing, transportation, gasoline and oil, and personal insurance consistently endure the largest impacts from inflation; real- income effects from inflation differ from those arising from a like cut in nominal income; not surprisingly, food expenditures are most impacted at low income.

由于2020年初的COVID-19大流行,美国和世界大部分地区的生产基本陷入停滞。美国的失业率迅速从2月份的3.5%上升到5月份的13.2%,GDP季度环比下降7.8%,政府实施了大量转移支付以维持家庭收入。由此导致的总供给和总需求之间的不匹配毫不奇怪地引发了通胀,到2022年初,通胀已达到40年来的最高水平。本报告的目的是利用从家庭消费支出调查中所包含的数据发展出来的框架来分析这种通货膨胀对不同类别支出的影响。分析的引擎是一个“预算内”系数矩阵,它代表了家庭预算中不同类别支出之间的直接关系,Taylor(2013)对其结构进行了详细描述。该矩阵的元素是根据正在进行的美国劳工统计局消费者支出调查中58个季度(2006年至2019年)的数据信息构建的,以分析2021-2022年通货膨胀对美国16类家庭消费支出的影响和影响。主要发现包括:住房、交通、汽油和石油以及个人保险支出始终受到通货膨胀的最大影响;通货膨胀对实际收入的影响不同于名义收入减少对实际收入的影响;毫不奇怪,食品支出在低收入人群中受到的影响最大。

The objective of this paper is to investigate the economics of production efficiency of dairy farms, with a specific focus on the role of agricultural policy. Our analysis is based on a representative sample of Irish dairy farms, ranging from 2000 to 2018, which includes a period of major change in EU dairy policy. Based on a multi-input multi-output production system, we first estimate technical, allocative, scale and scope efficiencies. We find significant heterogeneity in technical and allocative efficiencies, which change over time. We also calculate shadow prices of milk quota, which suggest that milk quotas restricted many farmers and limited their ability to produce milk. Finally, we explore determinants of technical, allocative, scale and overall inefficiencies using random panel-data censored regression. We find that subsidies are positively associated with farm efficiency, but the effects vary over distinct quota abolition periods. Overall, our empirical findings indicate that agricultural policy had important effects on the managerial effectiveness of farmers.

本文的目的是研究奶牛场生产效率的经济学,特别关注农业政策的作用。我们的分析基于2000年至2018年爱尔兰奶牛场的代表性样本,其中包括欧盟乳制品政策发生重大变化的时期。基于一个多投入多产出的生产系统,我们首先评估了技术效率、配置效率、规模效率和范围效率。我们发现,随着时间的推移,技术效率和配置效率存在显著的异质性。我们还计算了牛奶配额的影子价格,这表明牛奶配额限制了许多农民,限制了他们生产牛奶的能力。最后,我们利用随机面板数据截尾回归探讨了技术、配置、规模和整体效率低下的决定因素。我们发现补贴与农业效率呈正相关,但在不同的配额取消时期,这种影响有所不同。总体而言,我们的实证结果表明,农业政策对农民的管理效率有重要影响。
