In developing countries, there has been an increase in businesses that do not have a specific location and persist in informality. This research aimed to evaluate, from a gender perspective, the moderating effect of the decision not to have a place in the relationship between human capital (education, experience and type of entrepreneurship) and business informality.Design/methodology/approachUsing the National Household Survey 2014–2018, a sample of 50,313 Peruvian entrepreneurs was obtained − 23,314 women and 27,002 men – who have been in business for over three years. The data were analysed with logistic regression.FindingsThe results showed a moderating effect of entrepreneurship without a settled location on the relationship between education and informality in the case of women. And, for men, the moderating impact falls on the education, experience and reason for venturing that influences the formality of their businesses.Originality/valueThe problem of business informality of established companies with more than 42 months of operation is analysed. The moderating effect of the decision not to have a specific location on the relationship between human capital and informality is explored. This work extends business informality studies in Latin America developing countries, incorporating a gender perspective.","PeriodicalId":387315,"journal":{"name":"Academia Revista Latinoamericana de Administración","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130682085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within this industry, cooperativism stands out as a strategic component that influences the fixation of the rural population and the development of the territory. Likewise, innovation is fundamental for the competitiveness of companies. The aim of this study is to analyse the existence of a relationship between several business variables: strategy, culture, work climate, management, organisation and market orientation in the innovative performance of agri-food cooperative companies. Differences with other types of agri-food organisations are also analysed.Design/methodology/approachThe authors proposed a conceptual research model, which aims to determine the influence of several business variables on innovative performance. A qualitative methodology was used through a multiple case study where five Extremaduran agri-food cooperatives were chosen to carry out the research.FindingsThe results show that the business variables are valued positively as factors that enhance innovative performance. Moreover, the peculiarities of cooperatives show several differences with respect to non-cooperative companies.Originality/valueThe results contribute to agri-food cooperatives' managers developing specific actions that improve the competitiveness and sustainability of agribusiness based on innovation.","PeriodicalId":387315,"journal":{"name":"Academia Revista Latinoamericana de Administración","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121065594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data were collected in Brazilian public institutions active in the areas of education, finance, statistics and technology, and the hypotheses were identified and evaluated using the technique of partial least squares structural equation modeling (PLS-SEM).FindingsThe results identified that managers' self-determination is related to the perception of control, which, consequently, impacts the RG by providing feelings of competence and autonomy capable of building a beneficial relationship with the IT provider.Practical implicationsThis study promotes the understanding that upper management needs to support the autonomy of managers to increase their levels of intrinsic motivation when managing supplier deliveries.Originality/valueThe application of SDT to the IT outsourcing context provides new insights into the mediation of perceived control by explaining the relationship between managers' expectations and motivations as an important driver for RG.","PeriodicalId":387315,"journal":{"name":"Academia Revista Latinoamericana de Administración","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121685666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This result indicates that the risk increase is associated to weakening of the corporate governance of companies. Positive discretionary accruals also have the same impact on corporate risk. In addition, accrual-based earnings management has a non-linear impact on corporate risk. Higher institutional and financial development systemically reduces the risk of Latin American firms. Institutional development can mitigate the effects of earnings management on corporate risk.Originality/valueThese results support that AEM represents a practice that managers use to weaken firms' corporate governance and expropriate wealth from shareholders. These practices promote higher firm's risk. However, the institutional and financial development reduces the corporate risk and contributes to mitigate the impact of AEM on it. These results have relevant implications for firms' corporate governance because they warn the relevance to control AEM practices and its impact over corporate risk perception by investors.

In this context, the aim of this article is to compare the productivity determinants across firms operating in low and high knowledge intensity service sectors (low knowledge intensive sectors (LKIS) and high knowledge intensive sectors (HKIS)) in Ecuador.Design/methodology/approachThe authors use a two-step estimation method. The firm productivity is estimated in the first step and the productivity determinants in the second step. To achieve the objective, the authors use an unbalanced panel database on the financial statements from formal Ecuadorian firms for the period 2007–2018.FindingsThe authors’ results show that LKIS firms are slightly more labor-intensive compared to HKIS firms. Productivity determinants are similar across HKIS and LKIS firms, except for exports and market concentration. HKIS firms are more productive when the competition level is low, indicating that higher market power is associated with higher productivity. The influence of taxes on productivity depends on firm size. Small and medium-sized firms are more negatively affected than large firms.Practical implicationsTaxes should be designed considering the size of the companies, since these could affect their productivity. Thus, lower taxes to small and medium firms may reduce firm size inequality. In addition, the acquired knowledge of HKIS should be spread to other firms becoming a positive externality instead of an entry barrier.Originality/valueDespite the productivity determinants of the service sector has been recently explored, in contrast to the manufacturing sector, individual and contextual determinants are less identified.

It is also shown by the results that external factors do not affect the noneconomic performance or economic performance. Moreover, the results show the moderation effect of the noneconomic variable.
