The paper examines the role that informal sector employment plays in poverty reduction using data from the National Income Dynamics Study (NIDS). Using a Shapley decomposition approach, it finds that government transfers and formal sector jobs are the dominant drivers of aggregate poverty reduction. Informal sector jobs currently play a limited role in poverty reduction at the national level. This is primarily driven by the fact that there are relatively few informal sector jobs compared to formal sector jobs. On a per-job basis, the poverty reduction associated with formal sector jobs and informal sector jobs is quite similar. The poverty reduction associated with one informal sector job is generally between 50 to 100 per cent of the poverty reduction associated with one formal sector job (depending on the poverty measure, poverty line and year chosen). Therefore, from a poverty reduction standpoint, policy makers are encouraged to view job gains and losses in the informal sector approximately on par with gains and losses of formal sector jobs.

The reliability of Census data on demography and migration periodically comes under attack. This paper sheds light on the reliability of migration data with respect to the Western Cape. Census data and two independent studies are compared and the convergence or divergence of the findings assessed. Some of the findings at issue are that about 90% of Coloured, 20% of African and half of Whites living in the Western Cape in 2001, were born in this province (Census 2001 and PGWC). Another is that this applied to only 16% of African residents of Khayetisha (KMP) according to a survey of that area, compared with 30% according to Census 2001. The results of the comparisons are therefore mixed and qualified. There is higher consistency for more aggregate-level measures (provincial) than for disaggregated measures (magisterial district). For example, in the case of life-time migration, there were substantial differences in the results of the KMPS and Census 2001 for the Mitchell’s Plain magisterial district. On the other hand, the differences between the census and a non-Stats SA produced survey of the Western Cape Province, were less than 5% and can therefore be regarded as reliable. Accurate data on migration is essential for planning purposes. More comparative analyses such as that contained in this paper, are therefore called for.

This paper analyses the employment performance of enterprises in the informal sector, highlighting firms with employees and, in particular, paid employees. It uses StatsSA’s Survey of Employers and the Self-employed (SESE), which surveys owners of non-VAT registered enterprises. In contrast to the QLFS, the SESE provides data on enterprises, their owners and their employees. Whilst the general impression of the informal sector may be that of mostly one-person street traders or spaza shops, it finds that 21% of 2013 informal-sector enterprises had paid employees. These employing enterprises provided paid work to approximately 850 000 people (owner-operators plus paid employees), as well as 211 000 unpaid workers (probably paid in kind in some way). The paid component amounts to about twice the direct employment of the mining sector. Informal firms increasingly operate in non-trade sectors such as construction, financial and other services. The paper describes the characteristics of informal firms and analyse how these, such as premises and having accounts, are associated with the probability to employ. Linkages to LFS and QLFS data enable an analysis of the personal and household characteristics of the owners of informal firms. Regression analysis is used to get a multivariate grasp of the relationship between enterprise performance and the characteristics of firms and owners. The results make a compelling case that economic policies need to view the informal sector as an integral part of the economy, a heterogeneous sector with significant paid employment, which requires enabling policies – rather than as a ‘problem sector’ of hawkers and street traders mostly requiring regulation, compliance and policing.

There are many sources of South African employment data, including Statistics South Africa (Stats SA) household and establishment surveys and data series constructed by research organisations and private companies. Different South African research clusters tend to use different data sources that can produce contradictory labour market trends, and such inconsistencies may have contributed to the cluster-specific perspectives on the South African unemployment problem. This paper aims to evaluate critically the reliability of the two most popular data sources: the Stats SA household and establishment surveys. A comprehensive discussion of the sampling and surveying approaches used to obtain employment data is followed by a comparison of the resulting employment trends for the total non-agricultural formal economy, and at a one digit SIC industry level. It finds that the establishment and household surveys provide relatively consistent estimates of the long-run trend in total and industry-specific non-agriculture formal employment once the most obvious shortcomings in the data have been accounted for. Finally, panel data techniques are applied in combination with other data sources to investigate the relative reliability of the establishment and household employment data. There is evidence of measurement error in the employment estimates from both sources, but the household survey data appears to generally provide a more reliable reflection of employment growth during the period under consideration.

How should the correlation between the earnings of parents and children in South Africa be calculated in the presence of high unemployment, and what is the role of education in determining this relationship? The research uses the first four waves of the National Income Dynamics Study (NIDS) for 2008 to 2014/15, and the 1993 Project for Statistics on Living Standards and Development (PSLSD) to investigate the shape of the association between parental and child earnings across the earnings distribution, and finds that the correlation is strongest at the ends of the distribution. The paper corrects for possible biases that arise from co-resident parent-child pairs, and from selection into labour market participation in South Africa’s high-unemployment society. The research finds that correcting for selection into employment increases the intergenerational elasticity of earnings by approximately 10 per cent. The paper unpacks the role of education in determining the association of intergenerational earnings and finds that the impact is strongest at the bottom of the earnings distribution, and that education accounts for approximately 40 per cent of the total intergenerational earnings elasticity.

More than two decades since the advent of democracy in South Africa, the place of small-scale agriculture in rural development, poverty alleviation and food security remains ambiguous and highly contested. However, there is now some new evidence that official income poverty estimates in South Africa may be underestimating the contribution of rural, land-based livelihoods when measuring household well-being. This paper aims to explore this possibility further by identifying how household production activities are associated with improved food security among rural Eastern Cape households in the former homelands. The analysis is based on data from Statistics South Africa’s 2008/9 Living Conditions Survey and its annual General Household Surveys. The paper investigates trends and key patterns in household production in the Eastern Cape and compares these with other regions of South Africa. One of the key findings is that hunger levels are lower among farming households in the Eastern Cape even though a higher percentage of these households (relative to non-farming households) live below the national food poverty line. The paper concludes by discussing some implications for policy as well as the role of household production activities in meeting immediate food security needs.

This paper presents an analysis of the nature of, and recent trends in, the South African informal sector using Quarterly Labour Force Survey (QLFS) data from 2008-2014. The size of the informal sector, as a percentage of the non-agricultural workforce, has remained relatively constant, at between 16 and 18 per cent, over the period. Although smaller than developing country counterparts, this still constitutes a significant source of employment in the country, thus warranting analysis and policy attention. While previous analyses have paid attention to differentiation by income and status in employment, less attention has been paid to gender, industry and spatial differentiation. The paper analyses the following aspects: The impact of the 2008-09 economic crisis; gender reconfiguration within the informal sector; the informal sector and youth employment; improvements in educational levels; changes in industry composition; the geography of the African informal sector; and earnings. In reflecting on current policy responses to the informal sector, particularly at national level, we argue that a greater understanding of these variables, and how their role may have changed over time, is critical to robust and successful policy making. We explore policy implications in the conclusion.

The Competition Act’s objectives encompass addressing anti-competitive conduct in the interests of broader based participation in the economy. This paper considers literature on competition and inclusive growth. The enforcement of the Act by the Competition Commission, Competition Tribunal and Competition Appeal Court is reviewed, with a particular focus on abuse of dominance. In particular, it analyses the standards applied by the Competition Tribunal and Competition Appeal Court in their rulings and the implications of the institutional structure and practices for hearings. The paper locates its assessment in the context of the challenges of developing a more inclusive South African economy.

In 2010, a team of researchers undertook a survey of informal micro-enterprises, piloting a new method for researching township businesses in a spatial context. Using a small area census approach, the objective was to identify all existing micro-enterprises within an area of sufficient size (approx. 2km2/10,000 households) to adequately reflect the spatial dynamics of business distribution whilst enabling the researchers to obtain a qualitative understanding of enterprise dynamics. In 2015 the researchers returned to the field to resurvey the area. The research sought to identify measurable evidence of enterprise growth and/or change through documenting all enterprise activities and again recording the spatial distribution of each business. The comparative dataset provides a unique opportunity to reconsider questions about the township informal economy and examine how previously identified businesses have fared over time; how sectors have performed in relative and comparative terms; and the factors that have influenced shifts in business dynamics including spatial distribution. The 2015 research found that the number of micro-enterprise activities had doubled (from 879 to 1798) with growth recorded in all but two sectors. The paper argues that the change represents a deepening of entrepreneurial activity in Delft. One of the main drivers of change are survivalist businesses in the fast moving consumer goods market segment; the majority of these micro-enterprises are run by middle-aged women. The research found insubstantial evidence of businesses relocating to the high street, though there is evidence of fluid adaptability and innovation in the positioning of businesses and their product focus.

This paper aims to better understand the obstacles and risks faced by informal sector firms in South Africa and the insurance by firms against this risk. The paper examines informal firms in Diepsloot, an urban township north of the city of Johannesburg. Based on a unique enterprise survey dataset for the township, this paper firstly assesses factors driving the incidence and cost of crime against these enterprises. Second, it examines existing methods of risk-mitigation against crime-related events, with a focus on the access to formal risk-mitigation instruments. Finally, the paper evaluates the relationship between purchasing formal business insurance and firm performance. The findings show that crime is the most important perceived business environment obstacle for these informal firms, more important than other often emphasized obstacles such as access to credit. The paper finds that wealthier, better performing firms and those that rent non-residential business premises are more likely to experience losses due to crime. Importantly, we also show that there is a significantly positive relationship between being covered by business insurance and firm performance. This result has important implications for South Africa’s policies to improve financial access and enhance the efficacy of the informal sector, which is outlined briefly.
