Several empirical studies indicate that the existence of a large informal sector is a major obstacle to firms’ choices of innovation strategies. This paper aims to address this issue and investigates the effect of the informal sector on the innovation of formal firms in Greece.

Using the World Bank’s Enterprise Survey data, the impact of informal competition on formal firms’ innovation in Greece is investigated by testing whether formal firms use innovation as a tool to protect and sustain their competitive advantage vis-à-vis informal firms and whether overall and informal competition has an inverted-U relationship with the innovation of formal firms. The effects of bribing and other variables drawn from the empirical literature are also controlled for.

The findings fill a gap in the literature regarding the effects of the informal sector on formal economic activity in Greece, by indicating that the informal sector puts pressure on formal firms to innovate, in order to differentiate their product or service and enhance their productivity and by offering learnings to help policymakers to promote innovation in Greece.

The originality of this study is that it investigates the impact of informal competition on formal firms’ innovation in Greece, a developed economy with a large informal sector. It does so by focusing on the effects that formal firms’ informal practices have on their competitors’ innovation activities, and the role of informal competition in creating and sustaining a competitive advantage in Greece.

The International Labor Organization (2020) estimates that eight out of ten enterprises (i.e. own-account workers and small economic units) are informal worldwide. However, less is known about the internationalization of informal enterprises. Here, it is argued that economic blocs, such as sub-Saharan Africa, with a greater proportion of informal enterprises, may provide broader societal legitimacy for them to operate internationally. Thus, informal firms would need to collaborate with other firms to overcome their resource constraints. Geographic colocation is one way to facilitate positive interfirm interactions that promote networking and subsequently cooperation. The purpose of this paper is, thus, to addresses two questions. Firstly, how and to what extent does interfirm marketing cooperation in geographic colocation influence the internationalization of micro and small informal manufacturing enterprises? Secondly, how do the perceived benefits of local external economies moderate this relationship?

The study draws evidence from 125 randomly selected informal enterprises located in two major clusters in Ghana, using a mixed-method approach.

The partial least square - structural equation modeling (PLS-SEM) analysis applied revealed two central points. Firstly, sharing marketing costs allows informal firms to upgrade their phases of export development directly. Secondly, the linkage of increasing sales activities and local external economies encourages the progress of the phases of export development and the scope of internationalization. Results confirm that the cluster benefits of interfirm cooperation and local external economies on the informal firm internationalization process complement each other in addition to their linear relationship.

The study contributes to understanding the nexus of the informal sector, geographic colocation and the entrepreneurial internationalization literature. The results should motivate researchers and policymakers to approach informal firm internationalization through collaborative business activities.

This study aims to investigate the factors that affect the likelihood of formalizing informal sector activities in 13 Sub-Saharan African countries, using World Bank enterprise survey data collected between the periods 2009 and 2018. Notwithstanding the great contribution of the informal economy in Africa, developing countries may stand to gain more if they make inroads in formalizing the informal sector.

Since the dependent variable is binary taking the value of one if the firm is willing to formalize and zero otherwise, the study will employ a discrete choice probit model.

Results inter alia show that firms that are more likely to formalize are young, owned by individuals with high levels of education and, have registered before. Governments should therefore target firms that are young and provide them with information about the benefits of registration, and if these firms are owned by experienced and educated individuals, the likelihood for them to register would be high.

The study uses cross sectional data and therefore cannot capture time variant factors affecting the probability to register and also cannot correct effectively for endogeneity.

Governments should therefore target firms that are young and provide them with as much information as possible about the benefits of registration, and if these firms are owned by experienced and educated individuals, the likelihood to convince them to register would be high. They should also reduce the cost of registration so as to improve net benefits in line with the rational exit view.

Formalizing informal activities will help improve the performance of these firms, reduce vulnerable employment as well as crime, poverty and inequality. Providing decent operating and working conditions to informal players will reduce social and political unrest.

The African continent is home to many informal firms accounting for roughly 55% of economic activity with 90% of workers eking out a living in a sector that does not respect worker rights, provide decent working conditions and where changes in growth have done little to reduce its size. Regulatory reforms have also been implemented resulting in the number of start-up registration procedures falling from 11 in 2003 to seven in 2019. The uniqueness of Sub Saharan Africa in terms of entrepreneurial culture, political, institutional and economic conditions as well as lack of consensus in the extant empirical literature make this study pertinent.

The study seeks to differentiate informal firms with high-growth prospects by their resource acquisition acts and to improve identification of growth-oriented informal firms for effective design and targeting of support measures.

An original set of firm-level data was collected using face-to-face survey in Lusaka, Zambia. Six clearly defined criteria were used to sample informal firms, apart from general informal business. Regression analyses were conducted to test the association of different resource acquisition acts with two growth dimensions: number of employees and business earnings of the 325 informal firms sampled.

Accessing clientele beyond local market, linking up with formal businesses and acquiring information and knowledge via online sources were found influential to growth in business earnings. Surprising, acquisition of finance and skills showed no effect. Employment expansion, though widely used, may not be a stable indicator of informal firm growth.

The study highlights the relevance of the emerging entrepreneurship perspective to understanding the topic. It cautions against pre-setting a size threshold for sampling informal firms and against relying on employment expansion as the sole proxy of growth.

The findings prompt a rethink of the effectiveness of conventional support programmes to drive growth of informal firms such as funding and training. Directing support measures to target growth-oriented informal firms will lead to creation of decent and sustainable jobs and formalisation.

With an original firm-level dataset, the study challenges a long-held assumption that growth of informal firm is negligible and shows that segments of informal firms are sustainable and could attain significant growth and derives new insights into researching and supporting informal firm growth.

This paper aims to examine the factors associated with a household business entrepreneur’s decisions to formalise the firm at a multidimensions level.

The data set is a panel of 2,336 SMEs and household businesses from Vietnamese SME surveys during the 2005–2015 period.

This study elucidates how firm-level resources, entrepreneur characteristics and costs of doing business influence an entrepreneur’s decision to enter, the speed and the degree of formality.

This study provides insight into the origins of an entrepreneur’s decisions to the multidimensions of business formality through the lenses of the resource-based view, entrepreneurship and institution theories.

Threats from the informal sector have become an important concern among formal firms. As a response to these threats, formal firms can adopt product innovation (PI) and marketing innovation (MI) strategies to differentiate themselves. The purpose of this paper is to examine how firm-level technical capability and external institutional quality affect firms’ reactions to the threats from informal firms by adopting innovative activities.

Based on attention-based view (ABV), an empirical study is conducted by using firm-level data from the World Bank Enterprise Survey in 2013.

The findings indicate that when faced with competition from informal firms, formal firms will intensify their innovation activities in both MI and PI, and their technical capability mitigates the competitive threats from informal sectors and thus weakens the impact of informal competitors on the level of product and marketing innovations. Moreover, it is found that the improvement of institutional quality reduces formal firms’ urgency to introduce new products when facing informal competitors. However, this improvement strengthens the impact of informal rivalry on formal firms’ innovation in marketing methods.

Previous studies that investigate the influence of informal threats are focused on technological innovation (e.g., PI and process innovation) strategies, but little knowledge is provided on non-technological innovative strategies, such as marketing strategies (e.g., MI and organizational innovation). This study contributes to the innovation literature by delving into the circumstances under which PI and/or MI is adopted to counter informal rivals. The findings enrich ABV by investigating how inter-firm resource similarity and marketing commonality strengthen top managers' attention to competition from informal firms.

This paper aims to estimate the effect of agglomeration on the probability of being an informal firm in Cali, Colombia. Informal firms produce legal goods but do not comply with official regulations. This issue is relevant because, similar to other developing countries, the informal sector in Colombia employs more than 50 per cent of the workforce. The results of this study demonstrate that one standard deviation increase in agglomeration reduces by 52 per cent the probability of being informal. Results are consistent with the idea that informal firms benefit less from agglomeration because of legal restrictions that block the relationship with formal firms.

The objective of the present paper is to estimate the effect of agglomeration on the probability that a firm – given a location – chooses to be informal. The authors deal with endogeneity issues by using soil information related to earthquake risk, which reduces the height of buildings and therefore increases the cost of agglomeration. The analysis focuses on Cali, Colombia, where the informal sector employs 60 per cent of the workforce. The registration of economic activities is used as a criterion to identify informal firms, in such a way that the percentage of informal firms is 42 per cent.

The authors find that the effect of agglomeration is strongly negative. The probability of being informal diminishes by 52 per cent when agglomeration increases by one standard deviation. Results in this paper shed light on how formal firms tend to be localized in high-density commercial and industrial areas, while informal firms are localized in low-density and peripheral areas where the land for production is cheaper and where they can avoid the control of authorities.

Theory argues that spatial production externalities and commuting costs are among the main forces that shape the city’s internal structure. Externalities include effects that increase firms’ production, and therefore workers’ income, when the size of the local economy grows. The authors now have strong evidence that firms’ productivity is positively related with the volume of nearby employment. Most of the empirical findings concern firms in the formal sector and, accordingly, the literature says little about the effect of agglomeration on informal firms’ location. However, this effect is crucial for developing countries where informal work is the main option for less-educated workers facing unemployment.

This study aims to explore “what impact does competition from informal enterprises have on formal firms” within the Chinese economic and business environment.

The paper opted for an exploratory study utilizing the cross-sectional survey data “2012 China Enterprise Survey” conducted by the World Bank. The survey is composed of approximately 200 business-related questions across the spectrum of business operations. In all, 2,700 privately owned Chinese firms are included in the logistic regression analysis.

Results show the impact of informal firm competition upon formal firms in China are influenced by geographical location, industry sector, ownership profile, governmental ownership, online presence and the extent of obeying labor regulations or the time spent in handling the governmental regulatory environment. There is a competitive and complementary simultaneous intertwined relationship between formal and informal economy. It occurs in a formal economy not fully divorced from the structural inertia of the planned economy as it transitions to a market-based economy.

This paper extended the assumption of institutional theory and presented it as a dynamic view of the evolution of organizations. It contributes by offering a simultaneous dual relationship between the formal and informal economy. It also adds one more potential feature of populations in the population ecology theory.

This exploratory paper empirically examines the impacts of informal sector enterprises on formal sectors firms in China and proposes a dual force effect of the informal economy to the formal economy given the current Chinese institutional environment. The study also provides a platform for further research on the interactions between the formal and informal sectors in emerging markets.

The purpose of this paper is to understand labor market regulations and their consequences for the allocation of resources.

This paper constructs a theoretical model to study labor market regulations in developing countries and how it affects the allocation of resources between the less productive informal activities and more productive formal activities. It also provides empirical support for some theoretical results using cross-country data.

When workers are risk-averse and the market for insurance against labor income risk is missing, regulations that provide insurance to workers (such as severance payments) reduce misallocation. However, regulations that simply create barriers to the dismissal of workers increase misallocation and end up reducing the welfare of workers. This study also provides some empirical evidence broadly consistent with the theoretical results using cross-country data. While dismissal regulations increase the share of informal employment, severance payments to workers do not.

The empirical exercise is constrained by the lack of availability of good data on the informal sector.

The analysis of the alternative labor market regulations analyzed in this paper in the presence of risk-averse workers is an original contribution to the literature.

The purpose of this paper is to test the effect of informal finance and trade credit on the performance of private firms.

Based on a survey to private firms in 19 cities, the paper empirically tests the promoting effects of informal finance and trade credit on the performance of private firms in China.

It was found that informal finance and trade credit have positive effects on private firms' performance measured by ROA. The net income reinvestment rate of private firms is positively related to whether or not the firm adopts informal financing or trade credit financing. A private firm having limited access to formal finance is more inclined to rely on self‐funds and is more limited by financing choices. Informal financing and trade credit can relieve the tension of cash flow chain but cannot solve the financing constraints. The empirical results also show that bank credit is still not the main financing choice for private firms and has not yet played a promoting role in private firms' performance and growth. Informal finance is more important to promote performance in manufacturing industry, while trade credit is more effective in wholesale and trading industry. The results show the coexistence viability of informal financing channels and formal financial institutions in China.

The policy implication is the Chinese Government should take careful steps to regulate informal financing sources.

After some theoretical literature, such as Lin and Sun, this paper explores for the first time the effect of informal financing channels on the performance of private firms.
