This research investigates the long-run determinants of per capita food waste, using a monthly time series dataset collected from the Taipei City Food Scraps Recycling Program, covering a span of 19 years. In addition, this research introduces a new proxy for the food wastage rate, gauged by the ratio of edible-to-inedible food scraps. The results of time-series cointegration analysis show that per capita edible food scraps and socioeconomic factors are bound together over the long run. Specifically, per capita edible food waste displays a positive co-movement with food price, the working-age share, and household size, while exhibiting a negative co-movement with the old-age share. This insight empowers policymakers with the ability to foresee and tackle the food waste problem by acting on the municipality's demographic and economic structural change. Our analysis complements the existing studies that depend on cross-sectional individual-level data by adopting a long-run municipal-level time series perspective.

本研究利用台北市食物垃圾回收计划收集的每月时间序列数据,历时19年,探讨人均食物浪费的长期决定因素。此外,这项研究还引入了一种新的食物浪费率指标,用可食用与不可食用的食物残渣的比例来衡量。时间序列协整分析结果表明,人均食用残羹剩饭与社会经济因素在长期内是紧密联系在一起的。具体而言,人均可食用食物浪费与食品价格、工作年龄份额和家庭规模呈正相关,而与老年份额呈负相关。这种洞察力使决策者有能力通过对城市人口和经济结构变化采取行动来预见和解决食物浪费问题。我们的分析通过采用长期的市级时间序列视角,补充了现有的依赖于横断面个人水平数据的研究。[文献引用:Q11, Q13, Q18, D1]。

To fill an important gap in the literature on acquirer prediction, this paper investigates which factors contribute to the likelihood that a firm will choose to acquire a target company from the United States (US) food and agribusiness industry (FABI). It relies on existing literature and a conceptual model in identifying the determinants of the choice to be an acquirer. Rejecting the pooled ordinary least squares and random-effects models, the paper estimates a fixed-effects logistic regression model based on panel data on acquirers and nonacquirers of US FABI (USFABI) target companies. Contrary to the study's various hypotheses, the results suggest that (1) efficiency, profitability, and liquidity do not affect the likelihood of being an acquirer, but that (2) less-solvent, less-leveraged, and less-attractive firms are more likely to become acquirers (possibly to improve their solvency, profitability, and attractiveness). These contradictory results are attributed to the uniqueness of the USFABI sector. The mergers and acquisitions process may therefore be a way for acquirers of USFABI firms to strengthen themselves, not necessarily an expression of their financial strength. This analysis is useful to target companies, acquirers, transaction advisers, investors, regulators, and other merger and acquisition stakeholders. [EconLit Citations: D22, G24, G34, L66, Q14].

为了填补收购方预测文献中的一个重要空白,本文调查了哪些因素有助于公司选择收购美国食品和农业综合企业(FABI)的目标公司的可能性。它依赖于现有的文献和概念模型,以确定选择成为收购方的决定因素。本文摒弃了合并普通最小二乘和随机效应模型,基于美国FABI收购方和非收购方目标公司的面板数据,估计了固定效应logistic回归模型。与研究的各种假设相反,结果表明:(1)效率、盈利能力和流动性不影响成为收购者的可能性,但(2)低偿付能力、低杠杆和低吸引力的公司更有可能成为收购者(可能是为了提高它们的偿付能力、盈利能力和吸引力)。这些相互矛盾的结果归因于美国外商投资商会部门的独特性。因此,并购过程可能是USFABI公司收购方增强自身实力的一种方式,而不一定是其财务实力的体现。这种分析对目标公司、收购方、交易顾问、投资者、监管机构和其他并购利益相关者都很有用。[引用文献:D22, G24, G34, L66, Q14]。

The consumption of plant-based meat is increasing, reflecting consumers' concerns about health, animal welfare, the environment, and sustainability. However, plant-based meat consumption remains low owing to the barriers to shifting consumers to this nonmeat diet. We evaluate consumers' intentions to consume plant-based meat from the perspectives of exploratory behavior and the regulatory focus theory. We collect 642 valid responses and use structural equation modeling to explore the relationship between exploratory behavior, regulatory focus values, and plant-based meat purchase intention. exploratory behaviors encompass risk-taking, variety-seeking, and curiosity, while regulatory-focus values comprise promotion- and prevention-focus values. The results show that exploratory behaviors affect plant-based meat purchase intention. Promotion-focus value has a greater impact on purchase intention than prevention-focus value. Promotion-focus value mediates the relationship between exploratory behaviors and purchase intention, whereas prevention-focus value mediates the relationship between risk-taking and purchase intention. Drawing on consumers' consumption values, we reveal distinct managerial implications, such as providing important information and adopting online selling to attract buyers [EconLit Citations: Q01, Q13, Q55, Q56].

植物性肉类的消费正在增加,这反映了消费者对健康、动物福利、环境和可持续性的关注。然而,由于消费者转向非肉类饮食的障碍,植物性肉类消费仍然很低。我们从探索性行为和调节焦点理论的角度来评估消费者消费植物性肉类的意图。我们收集了642份有效回复,并使用结构方程模型来探讨探索性行为、监管焦点值和植物性肉类购买意愿之间的关系。探索性行为包括冒险、寻求多样性和好奇心,而以监管为重点的价值观包括促进和预防为重点的价值观。结果表明,探索性行为影响植物性肉类购买意愿。以推广为重点的价值观对购买意愿的影响大于以预防为重点的价值观。促进导向价值在探索性行为和购买意愿之间起中介作用,而预防导向价值在冒险行为和购买意愿之间起中介作用。根据消费者的消费价值,我们揭示了不同的管理含义,例如提供重要信息和采用在线销售来吸引买家[EconLit引文:Q01, Q13, Q55, Q56]。

Considering the growing demand for healthy and environmentally conscious food products in the United States, lamb and goat meat have proved to be beneficial alternatives to other red meats. This study investigates consumer trends and preferences for lamb and goat meat in Florida and sheds light on regional preferences for these products, providing groundwork for further studies. An online survey was conducted using 924 primary shoppers in Florida. Respondents were asked questions regarding demographic characteristics, behavioral qualities, and attributes associated with meat-buying consumers. A contingent valuation method was used to derive willingness-to-pay (WTP) estimates by having participants report the maximum price they would pay for one pound of shoulder cut from lamb or goat. This study focuses on WTP for lamb/goat meat and uses Tobit regression analyses to test relationships between WTP and the consumer attributes described. Various regression specifications were estimated in the analyses to examine the robustness of significant correlations. Results surrounding the consumer WTP were similar for lamb and goat meat, showing that: (1) adventurousness when tasting food is positively correlated with WTP, (2) younger generations (Millennials and Gen Z) tend to have a higher WTP than older generations (Baby Boomers and the Silent Generation), (3) having tasted/liked lamb/goat meat previously both seem to positively influence WTP, (4) importance of access to culturally significant food products is positively correlated with WTP for lamb meat only, and (5) identifying as Hispanic had a negative correlation with WTP for goat meat only.

考虑到美国对健康和环保食品的需求不断增长,羊肉和山羊肉已被证明是其他红肉的有益替代品。本研究调查了佛罗里达州消费者对羊肉和山羊肉的消费趋势和偏好,并揭示了这些产品的地区偏好,为进一步的研究提供了基础。一项在线调查对佛罗里达州的924名主要购物者进行了调查。受访者被问及有关人口特征、行为品质和与肉类购买消费者相关的属性的问题。通过让参与者报告他们愿意为一磅羔羊或山羊肩肉支付的最高价格,使用条件评估方法来得出支付意愿(WTP)估计。本研究的重点是羊肉/山羊肉的WTP,并使用Tobit回归分析来测试WTP与所描述的消费者属性之间的关系。在分析中估计了各种回归规范,以检验显著相关性的稳健性。关于消费者WTP的结果与羊肉和山羊肉相似,表明:(1)品尝食物时的冒险性与WTP正相关;(2)年轻一代(千禧一代和Z一代)的WTP倾向于高于老一辈(婴儿潮一代和沉默的一代);(3)以前尝过/喜欢过羊肉/山羊肉似乎都对WTP有积极影响;(4)获取具有文化意义的食品的重要性仅与羔羊肉的WTP呈正相关。(5)西班牙裔与仅食用山羊肉的WTP呈负相关。

This study develops new insights into the spillover effects of foreign multinational enterprises (MNEs) on local firms’ export market entry, using the case of Vietnam—a notable global manufacturing hub located in Southeast Asia. The empirical analysis is based on a disaggregated firm-level panel dataset of 25,032 observations of Vietnamese food processing firms during the period 2011–2016. The food processing industry is an essential part of the country's thriving manufacturing sector, with enormous potential for exports. The random-effects Probit estimation results suggest that the presence of foreign MNEs significantly raises the likelihood that private local firms become exporters and thereby start integrating into global value chains. Further regressions reveal that foreign presence is also linked to higher export intensity among domestic firms, and that the magnitude of the estimated spillover effects is conditional on the specific measures of foreign MNE presence, the ownership structure in local industry, and the size of local firms. The findings highlight the considerable potential for foreign MNEs to influence local firms’ export prospects and validate the policy efforts to attract foreign direct investment inflows to the examined industry.

本研究以越南--东南亚著名的全球制造业中心--为例,就外国跨国企业对本地企业进入出口市场的溢出效应提出了新的见解。实证分析基于 2011-2016 年期间越南食品加工企业的 25,032 个观察值的分类企业级面板数据集。食品加工业是越南蓬勃发展的制造业的重要组成部分,具有巨大的出口潜力。随机效应 Probit 估计结果表明,外国跨国企业的存在显著提高了当地私营企业成为出口商的可能性,从而开始融入全球价值链。进一步的回归结果表明,外国企业的存在也与国内企业更高的出口强度有关,而且估计溢出效应的大小取决于外国跨国企业存在的具体衡量标准、本地产业的所有权结构以及本地企业的规模。研究结果凸显了外国跨国企业影响本地企业出口前景的巨大潜力,并验证了吸引外国直接投资流入所研究行业的政策努力。

Dual manufacturers produce both their own brands and private label brands (PLs). Disclosing these manufacturers on PL packaging might exert quality and brand image effects, which could influence the perception differentials between national brands (NBs) and PLs. An experiment identifies moderating effects for these differentials, according to the NB image positioning (high and low) and the type of PL (standard and premium). For example, compared to the case when a low-image NB manufacturer is disclosed as the supplier of a standard PL, which is our reference, we propose a decrease in the quality and brand image differentials when: (1) the high-image NB supplies a standard PL, or (2) a low-image NB manufacturer is disclosed as the supplier of a premium PL. Whereas we will not expect any change when a high-image NB manufacturer is disclosed as the supplier of a premium PL. Our results partially support our expectations. [EconLit Citations: M21, M31, Q13].

双重制造商生产自有品牌和自有品牌(PLs)。在包装上披露这些制造商可能会产生质量和品牌形象效应,这可能会影响民族品牌(NB)和民族品牌(PL)之间的感知差异。根据民族品牌形象定位(高和低)和PL类型(标准和优质),实验确定了这些差异的调节效应。例如,与低形象NB制造商被披露为标准PL供应商的情况(这是我们的参考)相比,我们建议在以下情况下减少质量和品牌形象差异:(1)高形象NB提供标准PL,或(2)低形象NB制造商被披露为优质PL的供应商。然而,当高形象NB制造商被披露为优质PL的供应商时,我们不会期望有任何变化。我们的结果部分支持我们的预期。[引用文献:M21, M31, Q13]。

Previous research found that both soybean oil and heating oil futures should be used to hedge biodiesel price risk. This was sensible because blending mandates caused biodiesel prices to be driven by that of its primary input—soybean oil. Much has changed in recent years, with plummeting demand during the coronavirus disease (COVID) pandemic, biodiesel plants struggling to break-even in 2020, and then incurring losses in 2021 as soybean oil prices skyrocketed with the rise of renewable diesel—a relatively new biomass-based diesel fuel in high demand largely due to green policies in California. This study revisits the appropriate strategies for hedging biodiesel production risk and finds that soybean oil has become a less important hedging vehicle. [EconLit Citations: Q420, Q410, Q480, Q160, Q110, Q130].

以前的研究发现,豆油和取暖油期货都应该用来对冲生物柴油的价格风险。这是明智之举,因为掺混规定导致生物柴油价格受其主要投入品--豆油价格的影响。近年来情况发生了很大变化,冠状病毒病(COVID)大流行期间需求急剧下降,生物柴油厂在 2020 年努力实现收支平衡,然后在 2021 年出现亏损,因为随着可再生柴油的兴起,大豆油价格暴涨,而可再生柴油是一种相对较新的基于生物质的柴油燃料,主要由于加利福尼亚州的绿色政策而需求旺盛。本研究重新审视了对冲生物柴油生产风险的适当策略,发现豆油已不再是重要的对冲工具。[EconLit Citations: Q420, Q410, Q480, Q160, Q110, Q130].

Improving dietary diversity and nutrition intake among rural households is essential to promote sustainable rural development. In this study, we examine whether nutrition knowledge training increases rural households' dietary diversity, nutrition intake, and total calorie intake. We consider three macronutrients (proteins, fats, and carbohydrates) and three micronutrients (vitamin C, iron, and zinc) to capture nutrition intake. The doubly robust inverse probability weighted regression adjustment estimator is employed to estimate survey data of 765 rural households collected by the Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs of China. The results show that nutrition knowledge training enhances household dietary diversity, improves the intake of macronutrients in terms of proteins and fats and micronutrients in terms of zinc, and increases total calorie intake. In addition, the intake of nutrients and calories of males responds to nutrition knowledge training while that of females does not. The dietary diversity of females increases with nutrition knowledge training, whereas that of males is unaffected. {EconLit Citations: I12, I18, Q12, E24}.

改善农村家庭膳食多样性和营养摄入对促进农村可持续发展至关重要。在本研究中,我们考察了营养知识培训是否增加了农村家庭的膳食多样性、营养摄入量和总热量摄入量。我们考虑三种常量营养素(蛋白质、脂肪和碳水化合物)和三种微量营养素(维生素C、铁和锌)来捕获营养摄入。采用双稳健逆概率加权回归平差估计器对中国农业农村部粮食与营养发展研究所收集的765户农户调查数据进行估计。结果表明,营养知识培训提高了家庭膳食多样性,提高了蛋白质、脂肪等宏量营养素和锌等微量营养素的摄入量,增加了总热量摄入量。此外,男性的营养物质和热量摄入对营养知识培训有响应,而女性对营养知识培训没有响应。营养知识训练增加了雌性的饮食多样性,而雄性的饮食多样性不受影响。{EconLit引文:I12, I18, Q12, E24}。

Vegetables play a vital role in human health. However, the average vegetable consumption among Chinese rural residents does not meet the minimum intake (300 g/adult person/day) recommended by the Chinese Dietary Guidelines. Homestead gardening—defined as growing vegetables or other food for home consumption, usually in the backyard of the household or on collectively allocated garden land—can play a significant role in promoting vegetable consumption in rural areas of developing countries. But empirical evidence on the effects of homestead gardening in China is scarce. This paper sheds new insights on the impacts of homestead gardening on rural households' vegetable consumption. We employ the three-stage procedure instrumental variables methods to disentangle the endogeneity of the homestead garden variable and propensity score matching for robustness check. The results show that homestead gardening increases vegetable consumption by 12.7% on average. Further heterogeneous analysis shows that homestead gardening has a larger effect on those groups with vegetable intake levels in the middle of the distribution. The impact of homestead gardening was strongest for the consumption of dark-colored vegetables. Our results can provide new perspectives for future rural planning, dietary and nutritional health transformation, and precision policy formulation. [EconLit Citations: Q1, D1, Q13].

蔬菜对人体健康起着至关重要的作用。然而,我国农村居民的平均蔬菜摄入量没有达到《中国膳食指南》建议的最低摄入量(300克/成年人/天)。宅基地园艺——定义为种植蔬菜或其他供家庭消费的食物,通常在家庭后院或集体分配的菜园上——在促进发展中国家农村地区的蔬菜消费方面发挥着重要作用。但在中国,关于宅基地园艺效应的实证证据很少。本文对宅基地园艺对农户蔬菜消费的影响有了新的认识。我们采用三阶段程序工具变量方法来解开宅基地花园变量的内生性和倾向评分匹配的鲁棒性检查。结果表明,宅基地种植使蔬菜消费量平均增加12.7%。进一步的异质性分析表明,宅基地园艺对蔬菜摄取量处于分布中间的群体影响更大。宅基地园艺对食用深色蔬菜的影响最大。研究结果可为未来农村规划、膳食与营养健康转型、精准政策制定提供新的视角。[EconLit引文:Q1, D1, Q13]。

The impact of old-age pension on nutritional outcomes: Evidence from Kyrgyzstan 养老金对营养结果的影响:吉尔吉斯斯坦的证据

Extensive studies have discussed the economic and welfare effects of social pensions worldwide, while scant attention has been paid to their nutritional effects, especially in emerging economies. Using multitopic longitudinal survey data of households and individuals in Kyrgyzstan covering four waves of 2012, 2013, 2016, and 2019, this study aims to examine the impact of an old-age pension on the nutritional outcomes of the elderly and shed light on their underlying mechanisms. Our empirical identification rests on a propensity score matching with difference-in-differences estimation design to address the endogeneity problem of receiving an old-age pension. Overall, the results indicate that receiving an old-age pension has a significant and negative impact on body mass index and the probability of being overweight for males, while no significant impact of the old-age pension has been observed for females. Receiving an old-age pension has no significant effect on expenditure of food consumption, calorie intake, and macronutrient intake, while it significantly reduces the ratio of protein intake to total calorie intake. We also observe significant heterogeneity in the nutritional effect of an old-age pension across various education levels and income levels; the negative nutritional effect is more salient for elderly individuals who are relatively poor or who have lower education. Our findings provide profound implications for policies targeting improving the nutritional status of rural residents in emerging economies through the implementation of the old-age pension [EconLit Citations: H55, I15, I38].

广泛的研究讨论了世界范围内社会养恤金的经济和福利影响,而很少注意其营养影响,特别是在新兴经济体。本研究利用2012年、2013年、2016年和2019年四波吉尔吉斯斯坦家庭和个人的多主题纵向调查数据,旨在研究养老金对老年人营养结果的影响,并揭示其潜在机制。我们的实证鉴定依赖于倾向得分匹配与差中之差估计设计,以解决领取养老金的内生性问题。综上所述,领取养老金对男性体重指数和超重概率有显著的负向影响,而对女性没有显著的影响。领取养老金对食物消费支出、热量摄入和常量营养素摄入没有显著影响,但显著降低了蛋白质摄入占总热量摄入的比例。我们还观察到,养老金的营养效应在不同教育水平和收入水平之间存在显著的异质性;对于相对贫穷或受教育程度较低的老年人来说,营养不良的影响更为显著。我们的研究结果为新兴经济体通过实施养老保险改善农村居民营养状况的政策提供了深刻的启示[EconLit citation: H55, I15, I38]。
