Nevertheless, there exists a paucity of research examining the various factors influencing consumer interest in cider. This article undertakes an analysis of the cider consumption experience, with a specific focus on consumer preferences related to distinct quality attributes, encompassing factors like brand, organic certification, and protected designations of origin (PDO). This analysis also takes into consideration the socio‐demographic profile, frequency of consumption, and willingness to pay (WTP). Our study concentrates on the Canary Islands in Spain, an area where no formal certification system yet exists to differentiate locally produced cider in the market. Our data collection methodology encompassed face‐to‐face surveys administered to a probabilistic sample of 1000 respondents in the Canary Islands. The results demonstrate that consumers who place emphasis on quality attributes such as commercial brands, organic certification, and PDOs, tend to assign value to various cognitive aspects of the product. Conversely, those who do not prioritize these quality attributes tend to emphasize the affective dimension of the product and the specific consumption occasions. Additionally, consumers who accord the highest importance to PDOs exhibit a WTP a premium price. The findings of this study hold valuable implications for policymakers and cider manufacturers, aiding them in identifying opportunities for the promotion of Canary Islands cider, both within the local market and on a global scale.

However, the persistent cooperative conundrum poses challenges to the integration of agribusiness and farmer interests. Utilizing goal planning analysis, this study delves into the profit‐driven behavioral logic of agribusiness and farmers to elucidate the conditions that influence their reciprocal symbiosis across various investment sectors. Through the crisp‐set qualitative comparative analysis method, this investigation parses data from 109 instances of agribusiness initiatives in rural areas, identifying four pivotal conditions conducive to reciprocal symbiosis: the farmers' information abundance (in production/processing and sales), incentive policies (in production), agribusiness's professional capabilities (in productive services), and the scale of demand (in productive services). Additionally, five principal sufficient conditions emerge: “Investment in production * information abundance of farmers * ~natural risk”, “Investment in production * natural risk * professional ability of farmers * profit sharing”, “Investment in processing and sales * information abundance of farmers * ~market risk * ~bidirectional specificity”, “Investment in processing and sales * bidirectional specificity * market risk * ~profit sharing”, and “Investment in productive services * professional ability of agribusiness * demand scale”. These findings illuminate the multifaceted interactions that underpin successful agribusiness‐farmer synergies [EconLit Citations: L23].","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using three waves of the European Community Innovation Survey, our results show that the optimal level of APD varied depending on the industry in which the company operates (food manufacturing industry vs. the rest of manufacturing industries). Furthermore, social capital seems to be a crucial factor to mitigate the difficulties of leveraging very diverse knowledge from partners, especially in the food manufacturing industry. Moreover, the external environmental context where the firm is operating, measured as the growth competitive index that reflects the competitive level of the country, was shown to have an influence on the firms' innovative efforts.[EconLit Citations: M10, 013, 036].","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141197829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different types of CSPs had different cognitions, attitudes, and purchasing behaviors toward domestically produced and imported ingredients. Bento establishments, self‐service cafeterias, and noodle shops adopted higher proportions of domestically produced ingredients (DPIs), and they also had more confidence in these ingredients. On the contrary, table service restaurants, all‐you‐can‐eat restaurants, breakfast eateries, coffee shops, and fast food restaurants adopted higher proportions of imported ingredients. The results may be related to the food items purchased and catering services provided by different CSPs. Therefore, CSPs should be included in the scope and promotion of food and agriculture education so as to increase their emphasis on ingredients for health, increase their tendency to purchase DPIs, promote the disclosure of information on food producers and ingredients, and enhance the communications among food producers, buyers, CSPs, and dining‐out consumers.","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141113747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gallizo Larraz","doi":"10.1002/agr.21947","DOIUrl":"https://doi.org/10.1002/agr.21947","url":null,"abstract":"To guide consumers, wineries need credible attributes about the quality of their wines and its origin. In Spain, protected designations of origin (PDO) guarantee that the wine has been produced in a certain wine region in accordance with specific and officially regulated quality criteria thus providing elements of guarantee to the consumer. The objective of this work is to determine whether the belonging of a winery to a PDO is positively or negatively related to profitability. This analysis is important because based on its results, managers will have more knowledge to decide whether a winery is interested in joining the regional PDO or not. We performed an empirical study using a random‐effects generalized least squares regression analysis, with a sample of 1182 Spanish wineries, in which we determine the relation between belonging to eight of the major Spanish PDOs and winery profitability. The results show that wineries registered in these PDOs tend to have higher levels of profitability than wineries that have opted to remain outside, with these differences being significant in five of the eight PDOs analyzed. Additionally, the regression model reveals a positive relationship between PDO membership and winery profitability in six of the eight PDOs. Furthermore, the findings suggest that in some of these PDOs small wineries benefit the most from being part of a PDO due to their difficulties in having a recognized brand in the market, while belonging to a PDO seems to be less useful for large wineries that have greater resources to build their own quality brand. On the basis of these findings, the wineries now have more information to decide whether to stay in the PDO, join it, or focus exclusively on developing their own brands [EconLit Citations: L15, L66, Q13].","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141121549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this potential, there is limited understanding of the key drivers for smallholder commercialization. In this study, we utilize comprehensive three‐wave panel data collected from three major maize‐producing regions in Ethiopia to examine the role of agricultural cooperatives in promoting smallholder commercialization. Employing a double‐hurdle model, we smallholder commercialization as a two‐step decision process involving market participation and the extent of participation (sales quantity), conditional on market participation. Unobserved heterogeneity is accounted for using a correlated random effect procedure, and the potential endogeneity of cooperative membership is addressed through a control function approach. The findings reveal that cooperative membership increases the probability of market participation and the intensity of sales. However, further analysis demonstrates a heterogeneous relationship between cooperative membership and commercialization, underscoring the importance of targeted interventions to boost the contribution of cooperatives to rural development through commercialization.

To address these concerns, enhancing livestock productivity is crucial to mitigate these impacts, boost farm competitiveness, and increase food production. The understanding of production variability is key to this endeavor. This paper assesses the technical efficiency of cow‐calf beef production units in Uruguay, excluding dairy and feedlot operations. Using data from the 2016 National Livestock Survey and Wang's frontier model, we estimate a translog stochastic production frontier, incorporating bovine livestock units, land area, and equivalent working units as key inputs. This model also controls soil productivity, improved grazing areas, productive orientation (beef‐cattle systems or beef cattle‐ovine mixed systems), beef production system (cow‐calf, full cycle, and fattening operation), access to electric power, and agroecological regions. Furthermore, it explores factors affecting technical inefficiency, such as ownership (individual, corporate without contract, and corporate with contract) and land tenure types (owner, tenant, or other types), besides the presence of third‐party owned cattle, technical assistance (including veterinarian and agronomic), and specific beef cattle technologies (such as continuous bull presence, artificial insemination, ovarian activity diagnosis, pregnancy diagnosis, use of scales for classifying females, temporary and early weaning, and cows and heifers grazing together). Findings indicate an average technical efficiency of 71.3%. Notably, factors such as agronomic and veterinary assistance, artificial insemination, weaning practices, third‐party‐owned cattle presence, pregnancy diagnosis, land tenure, and ownership type significantly impact technical efficiency. Our findings suggest that within the specific segment of cow‐calf operations in Uruguay, there is a potential to enhance beef production by 40.2% through improvements in farm management.

The crossbreeds between Angus and Hereford with Brahman, that is, Brangus and Braford, have been successfully adopted across Argentina. However, little is known about the specific bulls' traits that drive the demand for genetic selection of cattle outside the Pampas. Obtaining the economic value of traits would help to identify the demand for adapting livestock production to different ecosystems while preserving the meat quality of Angus and Hereford cattle. We estimated hedonic price models using Brangus bull sales data from two cattle breeding ranches in the north of Cordoba province. We find that cattle ranchers prefer observed traits such as weight, coat color, and age, while genetic indicators such as Expected Progeny Differences (EPDs) have secondary importance. We argue that stronger preferences for red‐coated bulls, as opposed to black‐coated bulls, could be associated with the demand for reducing heat stress. In addition, the relatively weak association between EPDs and prices may be related to unobservable variables such as ranchers' characteristics, and that the value of genetics is implicit in the studs' reputation.

Specialization in such goods may create incentives for certain groups to hinder a country's institutional development. Therefore, in this article, we investigate the causal relationship between commodity exports and the institutional quality of 49 countries from 1997 to 2022. Given that commodity exports can both influence and be influenced by institutional quality, it is crucial to search for exogenous natural variations in commodity exports in combination with econometric modeling strategies. To address the endogeneity problem, we use a natural experiment—China's accession to the World Trade Organization—to establish a causal link between agricultural exports and institutional quality free from bias. Our results highlight that increased reliance on commodity exports is linked to detrimental effects on a country's institutions. It diminishes citizen participation, increases the risk of political violence, lowers public service quality, hampers private sector development, erodes trust in societal rules, and amplifies corruption. The findings confirm the negative relationship between commodity exports and institutional development. They also contribute to the resource‐curse debate by showing that agricultural exporters with abundant natural resources negatively impact institutions. Additionally, a causal relationship is established, demonstrating that focusing on commodity exports reduces institutional effectiveness, with the study's quality enhanced by using various commodity product bundles and alternating institutional quality measures.
