RESUMEN

BACKGROUND: Mental health problems disproportionately affect young people in developing countries. However, there is limited research on help-seeking behaviours and the social support systems that improve mental wellbeing among vulnerable youth populations. OBJECTIVE: This mixed-methods study aimed to examine the relationship between social support reciprocity and mental health among young informal construction workers in Nigeria, a population at high-risk for occupational and socioeconomic stressors. METHODS: A cross-sectional survey was administered to 686 informal workers to measure reciprocity, mental health-related quality of life, and covariates. In-depth interviews with 32 participants provided qualitative context. RESULTS: Quantitative analyses showed 25% of participants reported poor mental health. Reciprocity positively predicted mental health after controlling for covariates. Qualitative findings revealed reciprocity occurs directly between individuals as well as indirectly through trade unions and religious groups. Indirect exchanges through groups helped address limitations of direct support due to limited resources. CONCLUSIONS: This study fills important gaps in understanding how social relationships impact mental health in developing country contexts. Findings emphasize the role of collective action and community-based support systems in promoting mental wellbeing among vulnerable populations. Insights can inform culturally relevant, systems-level mental health interventions.

RESUMEN

In developing countries, informal sector is the primary job provider for a significant portion of the workforce. This study aims to analyze how jobs in the informal sector affect the unemployment dynamics of developing nations. To achieve this goal, we formulate a nonlinear mathematical model by categorizing the considered workforce into three distinct classes: unemployed, employed, and self-employed, and include a separate dynamic variable to represent vacancies within the informal sector. The proposed model is analyzed using the qualitative theory of dynamical systems. A threshold quantity known as the reproduction number is derived and using this, one can compute the job generation rate necessary to stabilize the system. It is observed that variations in the reproduction number lead to qualitative changes, such as transcritical (forward or backward) and saddle-node bifurcations in the formulated system. Moreover, we propose an optimal control problem to determine an optimal strategy for government policy implementation in enhancing the employment rate of unemployed individuals and promoting the self-employment of informal employees inside the informal sector. Further, the analytical findings are validated numerically. The obtained results suggest that promoting the self-employment of informal employees for job generation effectively reduces unemployment.

RESUMEN

BACKGROUND: Education is crucial for empowering women in the labour market. However, the choice of occupation may not always necessarily be determined by their level of education. OBJECTIVE: The present study seeks to answer two important questions: (1) Does education help in determining occupational choices of women working in the informal sector? (2) How do factors like number of dependents in the family, woman staying with family, migration status of a woman and the use of networks in the job-search process, affect the occupational choices of women working in the informal sector? METHOD: The study utilised the data collected from 476 women, working in the urban informal sector of three northern States of India. We have estimated multinomial Probit model to analyse the data. RESULTS: This paper argues that education level cannot be the sole premise for a woman to have a better occupational choice within the informal sector. Other factors play a relatively significant role in determining the choice of occupation by a woman. CONCLUSION: Working women in the urban informal sector have less autonomy in the choice of their occupation and the education levels alone cannot help in providing access to more hygienic, career enriching and well-paying options to them.

RESUMEN

Introduction: Little is known on the association between cross-shift changes in pulmonary function and personal inhalation exposure to particulate matter (PM) among informal electronic-waste (e-waste) recovery workers who have substantial occupational exposure to airborne pollutants from burning e-waste. Methods: Using a cross-shift design, pre- and post-shift pulmonary function assessments and accompanying personal inhalation exposure to PM (sizes <1, <2.5 µm, and the coarse fraction, 2.5-10 µm in aerodynamic diameter) were measured among e-waste workers (n = 142) at the Agbogbloshie e-waste site and a comparison population (n = 65) in Accra, Ghana during 2017 and 2018. Linear mixed models estimated associations between percent changes in pulmonary function and personal PM. Results: Declines in forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) per hour were not significantly associated with increases in PM (all sizes) among either study population, despite breathing zone concentrations of PM (all sizes) that exceeded health-based guidelines in both populations. E-waste workers who worked "yesterday" did, however, have larger cross-shift declines in FVC [-2.4% (95%CI: -4.04%, -0.81%)] in comparison to those who did not work "yesterday," suggesting a possible role of cumulative exposure. Discussion: Overall, short-term respiratory-related health effects related to PM exposure among e-waste workers were not seen in this sample. Selection bias due to the "healthy worker" effect, short shift duration, and inability to capture a true "pre-shift" pulmonary function test among workers who live at the worksite may explain results and suggest the need to adapt cross-shift studies for informal settings.

RESUMEN

BACKGROUND: Enrolment of informal sector workers in Ghana's National Health Insurance Scheme (NHIS) is critical to achieving increased risk-pooling and attainment of Universal Health Coverage. However, the NHIS has struggled over the years to improve enrolment of this subpopulation. This study analysed effect of social capital on enrolment of informal sector workers in the NHIS. METHODS: A cross-sectional survey was conducted among 528 members of hairdressers and beauticians, farmers, and commercial road transport drivers' groups. Descriptive statistics, principal component analysis, and multinomial logit regression model were used to analyse the data. RESULTS: Social capital including membership in occupational group, trust, and collective action were significantly associated with enrolment in the NHIS, overall. Other factors such as household size, education, ethnicity, and usual source of health care were, however, correlated with both enrolment and dropout. Notwithstanding these factors, the chance of enrolling in the NHIS and staying active was 44.6% higher for the hairdressers and beauticians; the probability of dropping out of the scheme was 62.9% higher for the farmers; and the chance of never enrolling in the scheme was 22.3% higher for the commercial road transport drivers. CONCLUSIONS: Social capital particularly collective action and predominantly female occupational groups are key determinants of informal sector workers' participation in the NHIS. Policy interventions to improve enrolment of this subpopulation should consider group enrolment, targeting female dominated informal sector occupational groups. Further studies should consider inclusion of mediating and moderating variables to provide a clearer picture of the relationship between occupational group social capital and enrolment in health insurance schemes.

RESUMEN

OBJECTIVES: This study aims to evaluated the effectiveness of participatory action-oriented training (PAOT) intervention for hypertension management among intercity van drivers. MATERIAL AND METHODS: This quasi-experimental study applied concept and process of participatory actionoriented training and self-management to guide the development of the intervention addressing improvement in hypertension management behaviors. A total of 104 intercity van drivers with uncontrolled hypertension in Thailand were recruited to participate in this program. The intervention group (N = 52) received PAOT program, while the control group (N = 52) received conventional program. Data on hypertension management behaviors, and blood pressure were measured at baseline, 1 month and 3 months after intervention. RESULTS: At 3 months after intervention, hypertension management behavior, and systolic blood pressure were significantly different between 2 groups (p < 0.05). CONCLUSIONS: This PAOT was found to be feasible and could potentially improve hypertension management, and blood pressure level of intercity van drivers. The program should be applied in further studies with other workplaces in both formal and informal sectors with different characteristics and other health issues.

RESUMEN

In the Maldives, the contribution of the informal sector to e-waste management is significant as a formal e-waste management system is not yet established. The opportunities for advancing the circular economy in the Maldives' e-waste sector rely on the possibility of its formalization. This study aimed to examine the current and anticipated situations of e-waste management in the Greater Malé Region of the Maldives, with a specific focus on formalizing the informal sector. Interviews and questionnaire-based surveys were conducted followed by statistical analysis of the data. The t-test performed for the consumer survey data (n = 202) suggests that formalization encourages consumers to engage with the informal sector, resulting in increased resource recovery. Thematic analysis of interviews conducted with both formal and informal sector stakeholders (n = 17) revealed that the informal sector plays a substantial role in managing e-waste. It also underscored the need for government assistance to enhance safety and productivity in this sector. Various opportunities and challenges for establishing a circular economy in the country were identified, such as the rise in e-waste generation, the presence of an active informal workforce, the lack of sufficient government support, and prevailing stereotypes among consumers regarding informal workers. These findings provide a fresh perspective on the solutions for waste management in the Maldives and open the door to further explore the significance of the informal sector and feasible formalization initiatives. This study could contribute to the literature on the role of the informal sector in waste management in the Maldives and other small island developing states.

RESUMEN

Objectives. The informal economy in Tanzania, as in many other developing countries, presents numerous workplace safety issues. This study was conducted in stone quarrying (SQ) and soil brickmaking (SBM) sites to assess workers' awareness and perceptions of safety practices, identify common workplace risks and hazards, and evaluate challenges hindering the implementation of workplace safety culture. Methods. A total of 173 workers responded to a semi-structured questionnaire and 15 workers were interviewed. Data were summarized using Stata (version 15). Results. More than 95% of the SQ and SBM workers were exposed to ergonomic hazards and related health risks, due to low awareness (90%) and unavailable leadership structures (>96%) for enforcing and overseeing the implementation of workplace occupational health and safety (OHS) regulations. Conclusion. Due to the lack of regulation and oversight, workers in the informal sector in Tanzania often face hazardous conditions that put their health and safety at risk. Workers use self-intuitions, observations, injuries and near miss incidences to improvise control measures and minimize hazardous risks. This study provides baseline information that can be used for evidence-based decision-making and policy formulation to safeguard workers' safety and health in the informal sectors of Tanzania.

RESUMEN

BACKGROUND: Most Togolese population earns their income from informal sector, and they are very often exposed to health outcomes. Cash transfers impact healthcare utilization by improving household's social capital, socio-economic status, lifestyle choice, and physical health. The aim of this paper was to analyse the impact of unconditional cash transfers on health care utilisation in informal sector households. METHODS: We used the propensity-score method to compare health care utilisation by households that received cash transfers from nonbeneficiary households and simulated a potential confounder to assess the robustness of the impacts of the estimated treatment (i.e., cash transfer). Data were obtained from a national survey that covered 1405 households. RESULTS: The results show that women benefited the most from cash transfers (73.1%). Our estimates indicate that health care utilisation increased by 28.3% among workers in the informal sectors who benefited from unconditional cash transfers compared to nonbeneficiaries. The greatest impact was found on agriculture households with an increase by 31.3% in the health care utilisation. In general, cash transfer beneficiaries are more likely to use public health centres; there was an increase in public health facility attendance of 21.3%. CONCLUSIONS: Cash transfers are a valuable social protection instrument that improve health care utilisation of populations in the informal sector. Policymakers could use cash transfer as the infusion of income and/or assets that may impact health outcomes. Cash transfers are an opportunity to alleviate barriers of access to health care by older people. Future research must examine impact of cash transfer on health of vulnerable groups such as older people, children, and people with disabilities.

RESUMEN

OBJECTIVES: To compare the direct and indirect medical costs for patients with suspected Lyme borreliosis according to whether or not they had used an informal care pathway. PATIENTS AND METHODS: We retraced the care pathways of participating patients by a prospective questionnaire survey and a retrospective analysis of care records. Direct and indirect costs were estimated using a micro-costing method from different perspectives. We compared the costs of patients who had consulted a "Lyme Doctor" (informal care pathway) with those who had only used the formal care pathway. Non-parametric tests were appraised the significance of the differences between the two groups of patients. RESULTS: Out of 103 eligible patients, 49 (including 12 having used an informal health care pathway) agreed to be investigated. Five expenditure items entirely borne by patients were significantly higher for patients following an informal care pathway: productivity loss (3041 ± 6580 vs 194 ± 1177 euros, p = 0.01), alternative therapies (3484 ± 7308 vs 369 ± 956 euros), biological tests sent abroad (571 ± 1415 vs 17 ± 92 euros, p < 0.01), self-medication (918 ± 1998 vs 133 ± 689, p = 0.02) and transport (3 094 ± 3456 vs 1 123 ± 1903p = 0.01). CONCLUSIONS: From the patient's standpoint, the informal care pathway involving consultation with a Lyme Doctor is far more expensive than the formal care pathway. More specifically, the patient has to bear the costs of alternative treatments and repeated, non-recommended examinations.

RESUMEN

Resumo Introdução: o mundo do trabalho apresenta profundas transformações que impactam no cotidiano e nos processos de subjetivação de trabalhadores, inclusive os informais, como os catadores de material reciclável. Seu trabalho tem uma constante importância socioambiental, produz múltiplos sentidos e, ao mesmo tempo, é atrelado a interdições e riscos. Objetivo: compreender os processos de aprendizado e inventividade no trabalho de catadores de material reciclável da região da Grande Florianópolis. Métodos: trata-se de uma pesquisa exploratória-descritiva, com abordagem qualitativa, com entrevistas semiestruturadas e observações do ambiente de trabalho. Foram utilizados mapas de associação de ideias como estratégia de análise das práticas discursivas, com a análise conjunta dos discursos, extraindo as similaridades entre as narrativas dos catadores. Resultados: foram entrevistados 14 catadores. Identificou-se que o processo de aprendizado das atividades laborais ocorreu no próprio cotidiano, principalmente com pessoas mais experientes, além do desenvolvimento de conhecimentos e habilidades com base na experiência. Quanto ao caráter inventivo dos trabalhadores, observou-se a utilização de regras, normas e princípios para os seus fazeres, que são compartilhados e renovados cotidianamente. Conclusão: evidenciou-se a relevância dos vínculos estabelecidos nas relações cotidianas, tanto para o aprendizado como para o compartilhamento de estratégias inventivas.


Abstract Introduction: the labor market brings profound transformations that impact workers' daily lives and subjectivation processes, including informal ones such as waste pickers. Waste picking has a reiterated socio-environmental importance, producing multiple meanings while being linked to interdictions and risks. Objective: understand the work learning processes and inventiveness of waste pickers in the metropolitan region of Florianópolis. Methods: this qualitative, descriptive and exploratory study used semi-structured interviews and fieldwork observations to collect the information necessary to answer the defined objective. Discursive practices were analyzed via maps of association of ideas and joint discourse analysis by extracting the similarities between the pickers' narratives. Results: a total of 14 waste pickers were interviewed. Learning took place in everyday relations, especially with more experienced pickers, with knowledge and skills being developed based on experience. As for the inventive axis, workers use rules, norms, and principles for their activities, which are shared and reiterated daily. Conclusion: results highlight the bonds established by waste pickers in everyday relations, both for learning and sharing inventive strategies.

RESUMEN

Introduction : Les maladies non transmissibles (MNT) sont en augmentation dans plusieurs secteurs d'activité. L'objectif de l'étude était de décrire les facteurs de risque des MNT chez des femmes fumeuses de poissons sur deux sites au Bénin relevant du secteur informel. Méthodes : Il s'agissait d'une étude transversale descriptive qui s'est déroulée pendant un mois du 25 Avril au 26 Mai 2019. La population d'étude a été constituée des femmes fumeuses de poissons des sites de Xwlacodji et de Djeffa ayant au moins deux années d'ancienneté. Les variables étudiées étaient relatives aux caractéristiques socioprofessionnelles, aux facteurs comportementaux et bio cliniques. Le recrutement des participants a été exhaustif. Un questionnaire standardisé inspiré de celui du STEPS-OMS a été utilisé pour la collecte des données. Une analyse descriptive a été effectuée. Résultats : Au total, 81femmes ont été incluses. L'âge médian des femmes était de 40 ans, avec un intervalle interquartile de [25-75] ; 17 (21%) étaient scolarisées ; 39 (48,14%) ont une ancienneté de plus de 20 ans. Les facteurs comportementaux se présentaient comme suit :1,23% tabagisme (cigarette) ; 69,14% consommation régulière de l'alcool ; 46,91% d'insuffisance d'activité physique ; 100% de consommation insuffisante de FEL. En ce qui concerne les facteurs biocliniques il y avait 56,78% de surcharge pondérale ; 32,1% pression artérielle élevée prenant en compte la prise d'antihypertenseur ; 5,4% d'hyperglycémie. Conclusion : La fréquence de certains facteurs de risque des MNT est élevée, la mise en place d'un programme de sensibilisation est nécessaire.

RESUMEN

Promoting decent work and sustainable economic growth within the framework of Sustainable Development Goal 8 (SDG 8) entails addressing gender inequality, the consequences of market economies, and the role of the informal sector while also considering environmental sustainability. Research on SDG 8 remains limited, often adopting an appraisal perspective, and the concept of decent work within this goal remains relatively unexplored. Additionally, the focus on the challenges and inadequacies of achieving sustainable economic growth through decent work in the context of SDG 8 is insufficient, resulting in significant knowledge gaps. To contribute to filling these gaps, this paper adopts a descriptive and critical review perspective, systematically analyzing 108 journal papers and reports to investigate the concept of decent work within SDG 8. The research addresses the challenges and inadequacies related to decent work embedded in SDG 8. The review reveals that while progress has been made in tackling gender inequality in the labor market, gender bias, income discrepancies, and underrepresentation of women in senior positions persist, hindering inclusive and sustainable economic growth, full and productive employment, and decent work for all - SDG 8. Moreover, SDG 8's focus on inclusive and sustainable development falls short of effectively addressing market economies' structural disparities, insecure working conditions, and exploitative labor practices. Additionally, support for informal sector workers, who lack essential rights such as legal protection and social security, remains insufficient. Ecological destruction is sometimes an unintended consequence of purely market-based labor markets with an emphasis on economic growth, with SDG 8 lacking sufficient integration of environmental sustainability in its framework. The novelty of this study comes from its in-depth, critical, and policy-focused analysis of the ideas around decent employment in the context of SDG 8. The findings underscore the importance of providing fair, safe, and secure employment opportunities to support economic growth and development while upholding workers' rights. In conclusion, we emphasize the crucial role of promoting decent work and sustainable growth in achieving SDG 8's overall objectives, as it directly impacts other SDGs.

RESUMEN

Many countries in sub-Saharan Africa are struggling to expand voluntary health insurance schemes to raise finances toward achieving universal health coverage. With more than three-quarters of the population without any insurance, the government of Tanzania has unsuccessfully tried to pass a Bill proposing a mandatory, nationwide scheme to cover the large and diverse informal sector. The Bill proposed an annual premium of ∼150 USD for a household of six or 65 USD per person. Studies in Tanzania and Kenya have shown that the majority of people in the informal sector are unwilling and unable to pay premiums as low as 4 USD, mostly due to poverty. Mandatory health insurance for the informal sector is not common in this region, mostly because it is difficult to enforce. Successful insurance schemes have included significant subsidies from tax revenues. Tanzania should not seek to raise funds for health through an unenforceable insurance scheme but rather should consider a largely tax-funded scheme for the informal sector. Contributions through low-cost voluntary schemes can enhance social contracts, reduce out-of-pocket expenditure, and promote efficient utilization. In addition, progressive health taxes should be imposed on harmful products (tobacco, alcohol, sugary drinks, etc.) to raise more funds while addressing the increasing burden of non-communicable diseases. Furthermore, efficiency in the use of scarce health resources should be promoted through realistic prioritization of public services, the use of Health Technology Assessment, and strategic purchasing.

RESUMEN

Electrical and electronic waste (e-waste) is considered as resource and secondary source of metals, and is being recycled for recovery of precious and base metals. But the processes of recycling and the waste generated during e-waste recycling in informal and formal sectors contribute toxic metals in to the environment. This work aimed to compare the environmental and health impacts of informal and formal e-waste recycling facilities at New Delhi and Bhiwadi Industrial area in India, respectively. Here, concentrations of Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sn, V, Zn, and Ag, and As in surface dust collected from informal and formal recycling sectors and their associated pollution, human health and ecological risk are presented. Metal concentrations were higher than the background levels in both sectors. Contamination factor (Cf), contamination degree (Cdeg), pollution load index (PLI), geo-accumulation index (Igeo) and enrichment factor (EnF) of metals indicated severe pollution levels in both sectors. However, contamination in informal sector was comparatively higher than the formal sector. Sampling sites in both sectors had very high ecological risk. Storage, dismantling/shredding and recycling techniques were contributors of metals in surface dust in formal sector whereas fumes deposition, re-suspension, and dried by-products during acid bath treatments were additional sources in informal sector. Metal pollution depends on metal(s), e-waste type(s) and recycling sector(s). Total non-carcinogenic health risk due to metals was 6.5E+00 and 6.0E+01 and 6.2E+00 and 5.5E+01 in adult and children in informal and formal sectors, respectively. Total carcinogenic risk was 3.3E-03 and 7.2E-03 in informal and formal sectors, respectively. Ingestion was major pathways of metals followed by dermal and inhalation and children were more prone to risk compared to adults. Formal sectors too cause metal pollution but to lesser degree compared to informal. More effective pollution control measures are required in formal sector to control environmental pollution.

RESUMEN

Improving waste and resource management (WaRM) around the world can halve the weight of plastics entering the oceans, significantly mitigate global heating and contribute directly to 12 of 17 sustainable development goals (SDGs). Achieving such results demands understanding and learning from historical evolution of WaRM. The baseline is 1970, prior to environmental legislation. Early steps in the Global North focused on the 'technical fix' within strictly enforced legal frameworks, first bringing hazardous wastes and municipal solid wastes (MSW) under control, then gradually ramping up environmental standards. Using modern technologies to the Global South often failed due to institutional and financial constraints. From 1990, focus switched to integrating technical and governance aspects: local institutional coherence, financial sustainability, provider inclusivity, user inclusivity, national legislative and policy framework. The Global North rediscovered recycling, using policy measures to promote segregation at source; this relied on new markets in emerging economies, which had largely disappeared by 2020. The Global South is making progress on bringing wastes under control, but around 2.7 billion people lack access to waste collection, while ~40% of collected MSW is open dumped or burned - a continuing global waste emergency. So, much remains to be done to move further towards a circular economy. Three policy priorities are critical for all countries: access to sustainable financing, rethinking sustainable recycling and worldwide extended producer responsibility with teeth. Extending services to unserved communities (SDG11.6.1) requires a people-centred approach, working with communities to provide both quality services and decent livelihoods for collection and recycling workers.

RESUMEN

This study was conducted in 15 artisanal stone quarries (SQ) and 22 soil brick-making (SBM) sites. Specific objectives were to: (i) quantify ambient concentrations of suspended particulate matter (PM) and gaseous pollutants and noise levels at SQ and SBM workplaces; (ii) critically evaluate the potential workplace hazards, and risk factors; and (iii) analyze potential health risks to workers. Gaseous pollutants, PM, and noise levels were measured by using portable digital devices. Social demographic information of 150 workers across the study sites was collected using a questionnaire. Quantitative data were summarized and exploratorily analyzed using Stata software. This study revealed that fuel burning in the SBM releases SPM up to 10-fold and CO gas up to 14-fold above the WHO-recommended time-weighted average exposure concentrations of 16.6 µg/m3 and 0.3 mg/m3, respectively. On average hitting with a pickax in SQ areas released noise levels of about 81.01 ± 6.8 dB[A]. Overall, the SQ and SBM workers were exposed to low concentrations of PM and noise levels when the measurements were taken. Long working hours for repetitive activities in hot-sunny (27.1 ± 2.3 °C) and low outdoor humidity 23 ± 1.5%, potentially increase epidemiological risks to vulnerable individuals and enhance worker exposures to inhalable PMs. Although workplace noise exposure below the regulatory threshold of 85 dB[A] may not cause immediate hearing damage, it can have a significant impact on workers' hearing health, cognitive performance, psychological well-being, and overall productivity. This study provides an overview of workplace conditions rather than an accurate representation of the actual worker exposure levels because personal breathing zone sampling devices were not used. This study provides baseline information for further research and can be used for evidence-based decision-making and policy formulation to safeguard worker safety and health in SQ and SBM sites in Tanzania.

RESUMEN

Background: Young people are increasingly seeking employment in the informal sector due to increasing global unemployment. However, the precarious nature of work in the informal sectors, coupled with the high risk of occupational hazards, calls for a greater need for effective healthcare for informal sector workers, particularly young people. In addressing the health vulnerabilities of informal workers, systematic data on the determinants of health is a persistent challenge. Therefore, the objective of this systematic review was to identify and summarise the existing factors that affect access to healthcare among young people from the informal sector. Methods: We searched six data databases (PubMed, Web of Science, Scopus, ProQuest, Crossref, and Google Scholar), which was followed by hand searching. Then we screened the identified literature using review-specific inclusion/exclusion criteria, extracted data from the included studies and assessed study quality. Then we presented the results in narrative form, though meta-analysis was not possible due to heterogeneity in the study design. Results: After the screening, we retrieved 14 studies. The majority were cross-sectional surveys and were conducted in Asia (n = 9); four were conducted in Africa, and one in South America. Samples ranged in size from 120 to 2,726. The synthesised results demonstrate that problems of affordability, availability, accessibility, and acceptability of healthcare were barriers to young informal workers seeking healthcare. We found social networks and health insurance as facilitators of access for this group of people. Conclusion: To date, this is the most comprehensive review of the evidence on access to healthcare for young people in the informal sector. Our study finding highlights the key gaps in knowledge where future research could further illuminate the mechanisms through which social networks and the determinants of access to healthcare could influence the health and well-being of young people and thus inform policy development.

RESUMEN

The closure of markets in the city of Ouagadougou due to COVID-19 pandemic has had consequences on the food security status of households, in particular households of informal sector. The objective of this paper is to analyze the effect of COVID-19 on households' likelihood to resort to food coping strategies taking into account their resilience capacities. A survey was carried out among 503 households of small traders in five markets in the city of Ouagadougou. This survey identified seven mutually inclusive food coping strategies which are endogenous and exogenous to households. Thus, the multivariate probit model was used to identify the factors explaining the adoption of these strategies. The results indicate that the COVID-19 pandemic has had an impact on households' likelihood to use certain food coping strategies. Furthermore, the results show that assets and access to basic services is the main pillar of household resilience that reduces how likely a household resort to coping strategies due to COVID-19. Therefore, strengthening adaptive capacity and improving social security of households of informal sector are relevant.

RESUMEN

Motivation: There are three puzzling features of sub-Saharan African tax systems: tax administrations maintain records on vast numbers of small enterprises that actually provide no revenue; they continually invest resources into registering even more of these "unproductive taxpayers"; and discussions about taxing small enterprises are framed by the ambiguous, misleading concept of the "informal sector." Purpose: To make sense of these separate puzzling practices and narratives by exploring the synergies between them, and the broader organizational and political interests that they serve. Methods and approach: There is little statistical or sociological information on the functioning of national tax administrations in sub-Saharan Africa. The analysis is based on the results of recent research; along with a thorough search for useful data; my own extensive interactions with African tax administrators and relevant international organizations; and a sensitivity to the political dimensions of taxation. Findings: The three features of tax systems that are individually puzzling make sense when examined holistically. The continual drive to register more taxpayers provides an unduly favourable impression of the extent of policy and managerial efforts to collect more revenue. The informal sector narrative locates the apparent cause of revenue scarcity in the alleged undertaxation of small enterprises and poorer people, and thus helps divert attention from failures adequately to tax more privileged Africans and larger enterprises. Policy implications: Be very wary of claims that it would be a good idea to invest resources in registering large numbers of new taxpayers in sub-Saharan Africa. Try to avoid using the term "informal sector" when discussing issues of tax policy and administration-it is confusing and diversionary.
