The closest concept in the management of dual structures is the so-called organizational ambidexterity (OA). We refer to it as “Individual–Collective Organizational Ambidexterity”. Thus, it is necessary to explore factors affecting the OA of the IUEE's organizations to benefit simultaneously from individual and collective potentials and form successfully. To do so, a model was designed by examining the factors affecting the OA capacity of the IUEE's organizations. The statistical population was organizations involved in the IUEE of 36 cities in Kermanshah province, one of the poorest provinces in IRAN (<i>N</i> = 2041). 328 valid responses were collected as statistical sample based on the sampling table of Krejcie and Morgan (from 1970), and through the proportional stratified sampling method. The main instrument was a questionnaire. Data were analyzed by SPSS version 26 and Smartpls3 software. The results showed among the factors studied, diversity, learning orientation, and promotion of entrepreneurial culture had a positive and significant effect on OA. Networking capacities and commitment to collaboration in the ecosystem did not significantly affect OA. OA also had a positive and significant effect on the performance of IUEE. The discussion eventually suggests the future directions of the research. The findings of this study can be used to develop IUEEs and achieve entrepreneurial cities.</p>","PeriodicalId":51632,"journal":{"name":"Annals of Public and Cooperative Economics","volume":"95 1","pages":"275-300"},"PeriodicalIF":1.6,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78458274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, insights into possible business models and organizational forms of FFOs remain fragmented. This study thus aimed to co-create FFO business models in order to assess the business models in the context of the regulatory framework and the value chain upgrading theory. The Input–Output scheme and the Business Model Canvas (BMC) were merged to create an analytical lens. Participatory workshops with two farmers’ organizations, each in Ethiopia and Tanzania, were conducted and triangulated with ten focus group discussions and 25 key informant interviews. The co-created business models reflected the grassroots entrepreneurial potential of smallholders to envision FFOs. The gaps requiring external support, namely the know-how in accessing microfinance, silvicultural practices, and entrepreneurship, were revealed. We argue that the transformation from a farmers’ organization to an FFO enables wood value chain upgrading. Diversifying wood with non-wood products is key for FFOs. Regardless of how the regulatory framework shapes external support, the local government plays a pivotal role in facilitating the connection between FFOs and (non-)governmental support actors. Through this research, we develop suggestions for further empirical studies and offer several recommendations for decision-makers.</p>","PeriodicalId":51632,"journal":{"name":"Annals of Public and Cooperative Economics","volume":"94 3","pages":"921-949"},"PeriodicalIF":1.6,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/apce.12413","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50137591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the plethora of studies on side-selling's antecedents, little is known about side-selling's actual consequences, particularly from the standpoint of cooperative members. In two studies, we aim to deliver a member-based assessment of side-selling's influence on critical cooperative benefits and explore possible solutions. In the first study, with survey data from 128 members of four fruit cooperatives in Greece, we show that side-selling has a negative effect on perceived cooperative benefits, even in the presence of other collective action issues (e.g., the influence costs problem). In the same study, we posit and demonstrate that side-selling's aversive impact on cooperative benefits can be appeased when members think that their cooperative's transparency regarding cooperative activities is high. In the second study, with interview data from 20 members, we find that different punitive (e.g., expelling members) and collaborative (e.g., fostering trust) solutions are considered effective. Accordingly, our article advances extant knowledge of an issue that strikes at the heart of cooperative activity and offers valuable insights to cooperative decision-makers seeking to confront it.</p>","PeriodicalId":51632,"journal":{"name":"Annals of Public and Cooperative Economics","volume":"95 1","pages":"177-199"},"PeriodicalIF":1.6,"publicationDate":"2023-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85994713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a panel of firms in 14 countries, we study total factor productivity (TFP) enhancers of utility and network services companies. We find that moving TFP closer to the technological frontier drives productivity growth at higher speeds in Asian countries than in European countries. We also find that financial leverage exerts a positive effect on TFP growth for larger infrastructure firms and that more financially developed countries utilize economies of scale through better use of financial resources. Large utility and transportation companies display a higher rate of TFP growth, indicating that a competition policy to encourage M&amp;As would be prudent for the utility/transportation sectors to maximize economies of scale. In contrast, we find diseconomies of scale for energy companies in some countries. Moreover, young network firms improve TFP growth faster than their peers in countries with fewer product market regulations. Therefore, policies should remove entry barriers while facilitating the departure of old and low-productivity firms from network markets. Finally, policymakers should offer well-targeted fiscal incentives for intangible investments to boost TFP because the accumulation of intangible assets such as digital technology promotes more scale economies through network effects.</p>","PeriodicalId":51632,"journal":{"name":"Annals of Public and Cooperative Economics","volume":"94 4","pages":"1273-1298"},"PeriodicalIF":1.6,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85010963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a content analysis method, we analysed and coded textual data from documentary and archival publications on the agricultural cooperatives in Kyrgyzstan published by the government, cooperatives and their unions and the reports of international organizations.

We found that even if the overall structure of cooperatives’ EE can be comparable to conventional enterprises, its sub-elements significantly differ for cooperative enterprises.

We document that the most important barrier to the adoption of E-commerce in Moroccan agricultural cooperatives is the lack of information related to the low digital literacy of the cooperatives in question.
