Various corporate governance theories indicate that governance in small and medium-sized enterprises (SMEs) differs to that of larger corporations due to the ownership-management function within the organizational structure. This article provides empirical evidence of enhanced firm value in a sample of listed SMEs resulting from certain corporate governance mechanisms related to managerial and ownership concentration. The empirical analysis conducted in this paper is based on a panel data set consisting of 108 small and medium-sized public firms on the Spanish alternative stock exchange over a time frame of five years (2015-2019). The results suggest that CEO duality, the controlling shareholders, and the second largest shareholders all improve firm value. Conversely, the ratio of independent directors has a negative impact on firm value. These findings are robust to alternative model specifications such as dynamic panel estimators (Generalized Method of Moments -GMM-) and instrumental variable methods. Overall, we show that the governance configuration of listed SMEs can mitigate several of the central issues, such as agency problems, that large corporations face.

The aim of this study is to analyze the effects of Organizational Learning (OL) and Entrepreneurial Orientation (EO) on the profitability of MSMEs. To this end, field research was conducted on a sample of 1,620 companies located in Argentina (630), Mexico (550), and Ecuador (440). The data collection was carried out between May and September 2020, through a structured questionnaire addressed to the highest level of the company. The results were analyzed and validated using the partial least square (PLS) structural equation modeling (SEM) statistical technique. This work contributes to the development of the literature on dynamic capabilities, social capital theory, and stakeholder theory. Our results reveal that Entrepreneurial Orientation is a determinant variable for generating better Environmental Corporate Social Responsibility (ESCR) practices and is key to increasing the financial profitability of MSMEs. Furthermore, it is found that ESCR is a variable that partially mediates between EO and the Performance of MSMEs.

Organizations must constantly try to prevent losses resulting from unforeseen events and fraud. Whistleblowing has emerged as the most efficient mechanism for detecting such risks, but this phenomenon has not yet been studied in SMEs. This research seeks to analyze the relationships between attitudinal, normative, and control beliefs on the whistleblowing of accounting professionals, contrasting the behavior between small and large accounting firms from the perspective of the Theory of Planned Behavior. By using the structural equation modeling (PLS-SEM) method on a sample of 559 Brazilian accounting professionals, the analysis shows that an individual’s perceptions and characteristics influence their whistleblowing practices depending on firm size. SME accountants are directly and negatively influenced by family management and control beliefs, but are positively influenced by the moderation of attitudinal beliefs and by the risks of the scenario.

This paper analyses the intention of Spanish companies to continue using telework after the end of the COVID-19 pandemic. With this aim, we consider the influence that the management of several variables related to one of the key stakeholders, employees, has on this intention. This line of study is of great interest, given the implications not only for the management of companies, but also for key aspects such as the goals of the 2030 Agenda for Sustainable Development. To this end, we start with a review of the relevant literature on this topic, which allows us to raise various research hypotheses. This is followed by an analysis of a sample of 1,879 Spanish SMEs though a binary logistic regression model, which shows the positive influence of managers’ university education and companies’ orientation towards innovation on the use of telework after the pandemic.

Human resource management (HRM) intensity is important for any type of business in which human resources play a vital role. However, little is known about HRM intensity in the context of small and medium-sized enterprises (SMEs). The aim of this study is to investigate the relationship between the formalization of HRM function and HRM intensity. The sample of the study consists of medium-sized enterprises operating in Sri Lanka. The results show that although the formalization of HRM function is low, HRM intensity is high. The findings also show that higher levels of formalization lead to a greater intensity in HRM practices.

Founder-entrepreneurs in SMEs tend to have an active role in shaping the business and the direction and management of their innovation strategies. During COVID-19, their understanding of risks and approach towards decision making has become very crucial as the market sensitivity changed drastically with various levels of challenges such as travel restrictions, national lockdown, reduced market demand and operational uncertainty. So far, there are very limited studies on the role of the founder-entrepreneurs from Chinese high-tech software SMEs in managing the business risks from the pandemic. This paper will address some of these gaps by presenting case studies of 9 successful high-tech software SMEs in China and discuss how their founder-entrepreneurs have engaged with the market, identified COVID-19 related risks and how they have made critical decisions to survive and explore new market opportunities for growth. As part of a longitudinal study, in-depth interviews were conducted with the founder-entrepreneurs at various stages of the pandemic to explore their progress with the business operation and management. The paper will discuss the role of the founder-entrepreneurs from SMEs in risk analysis and decision-making. It makes an important contribution to the growing literature on Chinese SMEs, and COVID-19.

Small and medium-sized enterprises (SMEs) are key drivers of economic growth and development. Innovation through digital transformation has the capacity to enable sustainability, competitiveness and customisation in products and services. However, adoption of digital technologies by SMEs to underpin sustainability outcomes is poorly understood. A systematic literature review identified an initial dataset of 1300 articles, which after screening and application of exclusion criteria resulted in a dataset of 64 articles for synthesis. Analysis was carried out according to three main areas, namely the technology aspects of digital transformation, sustainable development according to the triple bottom line (i.e. economic, environmental and social aspects), and the business characteristics of SMEs. In the latter case, business strategy and management, organizational structure, organizational culture, skills and qualifications, and leadership factors are identified from the literature. Furthermore, literature expressing the triple bottom line dimensions and the type of Industry 4.0 technology areas adopted are synthesized. Correlation of the data through bibliographic analysis is provided on the type of technology enabling SMEs towards a pathway for sustainable development as well as synthesis of future research directions arising from the study.

Globally, micro and small businesses require finance to support their business activities. Most of them have low profits because of the lack of support from the formal financial system. Micro and small businesses in developing countries have a dire need for financing start-ups and existing business operations. The lack of support from the formal financial system and the government forces them to explore other financial support mechanisms, making it important to investigate alternative financial channels. This paper investigates whether informal finance matters for micro and small businesses. We used a systematic literature review to answer the predetermined research question. Thirty (30) primary studies were surveyed to establish the importance of informal finance for micro and small businesses. The findings show that informal finance is a workable alternative for micro and small businesses. It supports business start-ups, existing businesses and enhances business growth, business owners’ livelihoods and livelihoods in their communities. Informal finance models can be improved to work as small business promotion tools. The original value of the paper is based on the use of a systematic literature review to assess whether informal finance matters for micro and small businesses and connect theories with emerging themes. It further contributes to the debates on the importance of informal finance and contributes to future lines of research on informal finance.

This study aims to identify the determinants of the capital structure of SMEs in Algeria during the period 2010-2018. Where a sample consists of 20 SMEs from the Public Works and Hydraulics sector. The study used financial leverage as the dependent variable and assets structure, profitability, liquidity, and size as independent variables. The study used Panel Data methods for testing the hypothesis. The results show that profitability, liquidity, and assets structure are negatively related to financial leverage, while size does not affect the financial leverage. The results indicate that SMEs in Algeria rely on their internal resources to finance their activities.

This work empirically analyzes the competitive factors that help make micro, small, and medium enterprises (MSMEs) successful. To do this, an empirical study with a sample of 614 companies in Guanajuato, Mexico, has been carried out. The results of the binary logistic regression analysis show that quality, technology, and innovation are the main variables that determine a company’s success. These findings could provide guidelines to help MSMEs improve their competitiveness, and they could help public administrations better support MSME growth.
