The effect of COVID-19 on Canadian food security is examined from two different perspectives. COVID-19 creates a unique “income shock” that is expected to increase the prevalence of household food insecurity. This food insecurity can be measured by utilizing the Canadian Community Health Survey (CCHS). More fundamentally, COVID-19 heightens household concern about the capacity of the Canadian food system to ensure food availability. Despite surges in demand and supply chain disruptions, we currently do not observe broad, rapid appreciation in food prices. This suggests that there is an adequate supply of food for the near term. There is less certainty over intermediate and longer time periods because so many factors are in flux, particularly the rate of increases in sicknesses and deaths across the country and globally. Data on these health factors and elements of the food supply chain are needed to predict beyond a short time frame. In this regard, we discuss three ongoing considerations—ease of capital flows, international exchange, and maintaining transportation—that will help ensure food availability in the longer run. 相似文献

Canada's cattle/beef sector has already weathered a shock after a 2003 case of BSE resulted in closed borders and industry restructuring. Now, the sector has to adjust to similar shocks due to COVID-19. This paper examines the supply chain from the consumer up to the cow–calf producer by considering consumer reactions, labor market constraints, and supply response. A quarterly market model of North American cattle and beef markets is used to examine price and revenue impacts associated with the market disruptions. Depending on the scenario, there is considerable price and revenue suppression at all levels of the market. 相似文献

Summary This paper adapts the distributed lag model developed by Koyck to explain the propensity of developers to create retail space. The determinants of the stock of retail space are critically important to developers, lenders, appraisers, and researchers. The model is tested using retail sales data from the counties of North Carolina, USA. Results show that it takes more than 4 years for one‐half of the increased retail space resulting from expanded retail sales to be brought to the market. These extensive lags in the adjustment process indicate prolonged cycles in markets for retail space. 相似文献

The COVID-19 pandemic has put unprecedented strain on food supply chains. Given the ever-increasing degree of globalization, those supply chains very often stretch across international borders. In the short run, countries have largely been working to keep those supply chains intact and operating efficiently so that panic buying is cooled and shifts in consumption habits arising from personal isolation can be accommodated. Once the crisis has passed, based on what has been learned regarding the international food system's resilience, governments may wish to strengthen institutions that govern international trade. On the other hand, based on their COVID-19 experience, governments may feel that they are too dependent on foreign sources of supply and may wish to reverse the impacts of globalization on their food systems. As a result, they may become increasingly isolationist, eschewing international cooperation. Which of these opposing forces will prevail may depend on the paths economies follow after the disequilibrium precipitated by the pandemic. 相似文献

The coronavirus 2019 (COVID-19) pandemic and the Russia–Ukraine war have demonstrated that the neoliberal system is unstable during global crises. In times of crisis, exporter countries adopt protectionist policies in the form of export restrictions to safeguard their local food supply and curb inflation. Consequently, low-income countries might find themselves unable to access essential food products. In this regard, the aftermath of the COVID-19 pandemic and the Russia–Ukraine war has gradually increased export restrictions, causing severe food supply disruptions. In particular, import-dependent countries cannot access essential food products and face famine. To this point, this study explores the vulnerabilities of neoliberalism when exporter countries turn to protectionism. Moreover, it asks whether food sovereignty and self-sufficiency could act as a safeguard for import-dependent states against such vulnerabilities. In doing so, the study aims to contribute to the literature by linking protectionism with export restrictions, diverging from the more common association of protectionism with solely import restrictions. 相似文献

In the United States, truck rates for perishable food, the per-mile rate charged for trucking services to move perishable food from farms to stores, rose substantially in the post-COVID-19 pandemic era. We argue that rising truck rates is a signal of a broader shortage of truckers, but the connection between labor shortages, rising truck rates, and a lack of trucking services has yet to be established empirically. In this paper, we develop an empirical examination based on an equilibrium job search, matching, and bargaining framework in which we estimate the role of labor shortages in accelerating driver-wage growth, and truck rates for agricultural products. We estimate the model by combining US Bureau of Census Current Population Survey data on truck driver wages with USDA-Agricultural Marketing Service Service data on truck rates to establish the linkage between trucker supply and the demand for trucking services. We find that the COVID-19 pandemic was responsible for a rise in for-hire trucker wages of some , a rise in average truck rates of nearly and that the gap between trucker-job openings and successful matches explains a significant, but small, rise in truck rates. 相似文献

The Berry, Levinsohn, and Pakes (1995) market equilibrium model is extended to the supermarket chain level to examine consumer choices and retail competition for thirty-seven brands of breakfast cereals in Boston. Estimated taste parameters for product characteristics vary significantly across consumers. Although consumers are price-sensitive with respect to their chosen cereals, they exhibit strong brand and supermarket loyalty. Retail markups increase and marginal costs decrease with grocery market shares, attesting to oligopoly power with efficiencies. Markups decrease with the own-price elasticity of demand, with Corn Flakes having the highest markups. A detailed picture of consumer response and supermarket competition is provided. 相似文献

研究分别从贸易历史、国际比较和模型模拟的视角对中国未来食物供求平衡状况进行了展望和模拟分析。(1)贸易历史的角度的经验结果显示,中国食物贸易净进口呈扩大态势;(2)中国大陆与日本、韩国及中国台湾地区的国际比较结果表明,中国未来粮食净进口可能会进一步扩大,尤其是对蛋白质来源食物需求可能会快速扩张;(3)基于中国食物供求局部均衡模型的模拟分析结果显示,中国谷物和油料作物供求平衡的缺口将不断扩大,主要谷物和油料作物的自给率将不断下降,同时,中国采取的玉米产业需求抑制政策对中国粮食供求平衡具有深远影响。综合以上不同视角的结果可以看出,要根本解决中国食物供求平衡问题,有必要建立食物安全与其他安全的综合安全观,实现4个方面的战略转变。即:第一,从重视确保数量向重视确保国内外资源战略转变,如签订粮食供给的政府间协议。第二,从重视总体粮食安全向重视主食安全、区域安全、运输安全(或航道安全)、流通和分配渠道安全、不同收入群体家庭食物安全转变。第三,从重视单一的食物安全向产业安全和质量安全转变。第四,从重视本国食物安全向全球视角转变。 相似文献

COVID-19 has caused major disruptions to agricultural supply chains around the world. Researchers and policy-makers are interested in identifying means to reduce the disruptive effects caused by the pandemic. We investigate the impacts of COVID-19 on the operation of e-commerce stores (in short, e-stores) specialising in agricultural inputs. The difference-in-differences method (DID) is employed to estimate the causal relationship between COVID-19 and online sales of agricultural inputs using data from 54,244 agricultural input e-stores registered in 118 prefecture-level cities across 15 provinces and hosted on two major Chinese e-commerce platforms. The results show that COVID-19 led to a substantial growth in monthly sales of agricultural input e-stores, and this growth of online sales varied across store scales and by types of agricultural inputs. In particular, e-stores selling seeds and seedlings experienced a larger growth in sales than stores selling agricultural machinery and implements, and the mid- and larger-scaled e-stores experienced more growth of sales than micro- and small-scaled e-stores. Further analysis reveals that the growth of online sales of agricultural inputs was driven mainly by an increase in the quantity of customer orders (QCO). The findings of this paper underscore the importance of e-commerce in ensuring the resilience of the agricultural supply chain during the pandemic period. 相似文献

This article addresses the demand and challenges for local brand milk and focuses on the marketing strategies for retail promotion. While federal and state government make efforts to promote local food purchases and consumption at the farm level, local foods face significant distribution challenges in grocers, especially in larger retail stores. Limited shelf space and high pricing by retailers impedes consumers’ purchases and results in weak competitiveness for local brands. Therefore, it is essential for local producers and “buy local” programs to understand what types of promotion and marketing strategies might be more effective in stimulating demand in retail outlets. Using 2010-2011 Nielsen Retail Scanner data in the Northeast region, we estimate a random-coefficient discrete choice model of demand to determine the effects of nutritional characteristics, price, packaging, and distribution strategies on the consumers’ choice to purchase locally branded milk. Results show that local brand milk faces significant demand challenges in addition to high prices and limited outlets in competing with lower-priced products. Marketing strategies, such as price cut, one-gallon package offering, and expanded presence in retail stores, can significantly stimulate the demand for locally branded milk, with one-gallon package offering being the most effective strategy. 相似文献

Abstract This paper aims to identify the critical factors that support European food retailers' internationalisation via an investigation of the importance of Dunning's eclectic paradigm advantages (ownership, location and internalisation). Senior managers from seven firms that operate in the Greek food multiple retail sector were interviewed, and three propositions were put on test. In general, the findings indicate the critical role of the internalisation advantage during the international expansion of European food multiple retailers into that market. The findings also reveal that this advantage is the main superior and sustainable competitive element that European food multiple retailers possess when competing with local firms. The latter can be considered as an extension to the findings of previous studies that have exclusively emphasised the importance of ownership advantage factors in the course of the retail internationalisation process. 相似文献

Food waste occurs throughout the entire food supply chain, from production to consumption of food in households. Retailers are in a unique position to contribute to food waste avoidance, not only by minimizing the amount of waste in their distribution channels but also by influencing consumer attitudes and behaviors. This explorative study aims to identify which food waste avoidance actions are conducted by retailers in Denmark, to which extent, and how they vary across food categories and supermarket chain. Based on an analysis of secondary and empirical data collected via observations at retail stores, the authors identify 22 food waste avoidance actions in Danish retail. The results provide new insights into food waste avoidance in retail. Based on the findings, suggestions for further research directions are developed that should serve to identify the most efficient customer targeted actions in the in-store setting and marketing of suboptimal foods. 相似文献

There is a great potential for wine to deteriorate during shipment and storage of wines being exported from the United States to China. Certification of storage conditions such as that provided by the Hong Kong Quality Assurance Agency (HKQAA) is a key bridge to protecting quality and maintaining value in the auction market there. A literature review and semistructured interviews with winery managers, freight forwarders, transportation experts, and representatives of HKQAA provide qualitative analysis of barriers and bridges to protecting quality. The article presents a strong case for the adoption of storage and transportation standards for wine, such as the Wine Storage Management System implemented by HKQAA. Looking at wine exports through the lens of Total Quality Management provides the basis for recommending formal certification. 相似文献

The agro‐food sector has experienced a profound transformation of contractual arrangements along the value chain, coinciding with important technological innovations and product quality upgrading. Our understanding of the impact that this transformation has had on trade flows in the agricultural sector is very limited. In particular, we have limited knowledge about the extent to which the patterns in agro‐food trade have been driven by the quality of contractual institutions. Using existing measures which capture the sensitivity of agro‐food products to contractual imperfections, we show that countries with better contract enforcement specialise in the production of food which requires higher level of relationship‐specific investments. We also find that countries with better contracting institutions and producing contract‐intensive goods specialise in exporting high quality foods. In addition, we show that the quality of contracting institutions might importantly affect the process of product quality upgrading. 相似文献

This paper uses comprehensive and long time series monthly food price data and a panel dyadic regression framework to evaluate the impact of the COVID-19 pandemic and associated policy responses on spatial market integration across a diverse set of food items in Nigeria. The empirical results reveal several important insights. First, we show that a significant slowdown in the speed of adjustment and price transmission occurred during the pandemic. For some food items, the speed of adjustment and, by implication, spatial market integration weakened by two- to-threefold after the outbreak of the pandemic. The effect was especially pronounced for perishable food items. Second, lockdown measures and the spread of the pandemic triggered additional dispersion in market prices across markets. For example, lockdown measures were associated with a 5%–10% reduction in the speed of readjustment toward long-term equilibrium. Third, additional underlying attributes of markets, including lack of access to digital infrastructure and distance between markets, exacerbated impacts associated with the pandemic. For instance, access to Internet service reduced the slowdown in the speed of adjustment caused by the pandemic, but longer distances between market pairs induced greater slowdown in the speed of price transmission. Our findings offer important insights for revitalizing the efficiency of food markets affected by the pandemic. The heterogenous impacts of the pandemic across value chains and markets reinforce the need to properly target post-pandemic recovery interventions and investments. Finally, we offer some insights to reduce the vulnerability of food and market systems to disruptions in future pandemics or similar phenomena that inhibit food marketing and trade. 相似文献

粮食安全问题是目前城镇化进程中的风险之一.通过分析后认为,城镇化过程中粮食总体消费弹性区间呈收窄趋势,粮食刚性需求越来越大,这一现象在城镇地区相较于农村地区更为显著.其次,虽然粮食产量持续增长,但由于不确定性的增多,农产品供给难以保持与需求同步增长,一旦发生粮食减产,势必从多方面威胁到我国的经济形势. 相似文献
