The paradoxical surplus of health workers in Africa: The need for research and policy engagement.

In many countries in Africa, there is a 'paradoxical surplus' of under and unemployed nurses, midwives, doctors and pharmacists which exists amidst a shortage of staff within the formal health system. By 2030, the World Health Organisation Africa Region may find itself with a shortage of 6.1 million health workers alongside 700,000 un- or underemployed health staff. The emphasis in policy debates about human resources for health at most national and global levels is on staff shortage and the need to train more health workers. In contrast, these 'surplus' health workers are both understudied and underacknowledged. Little time is given over to understand the economic, political and social factors that have driven their emergence; the ways in which they seek to make a living; the governance challenges that they raise; nor potential interventions that could be implemented to improve employment rates and leverage their expertise. This short communication reflects on current research findings and calls for improved quantitative and qualitative research to support policy engagement at national, regional and global levels.

Food and beverage purchases at formal and informal outlets in Mexico.

OBJECTIVE: To examine food and beverage purchasing patterns across formal and informal outlets among Mexican households' and explore differences by urbanicity and income. DESIGN: Cross-sectional study of a nationally representative sample of households. We calculated the proportion of total food and beverage expenditure in each household by food outlet type overall and by urbanicity and income. We defined informal outlets as those which are not registered or regulated by tax and fiscal laws. Since some of the outlets within community food environments do not fall in clear categories, we defined a continuum from formal to informal outlets, adding mixed outlets as a category. SETTING: Mexico. PARTICIPANTS: Mexican households (n 74 203) from the 2018 National Income and Expenditure Survey. RESULTS: Of the total food and beverage purchases, outlets within the formal food sector (i.e. supermarkets and convenience stores) accounted for 15 % of the purchases, 13 % of purchases occurred in outlets within the informal food sector (i.e. street markets, street vendors and acquaintances) and 70 % in fiscally mixed outlets (i.e. small neighbourhood stores, specialty stores and public markets). Across levels of urbanicity and income, most food and beverage purchases occurred in mixed outlets. Also, purchases in informal and mixed outlets decreased as levels of urbanicity and income increased. In contrast to informal outlets, purchases in formal outlets were most likely from richer households and living in larger sized cities. CONCLUSIONS: Understanding where Mexican households shop for food is relevant to create tailored interventions according to food outlet type, accounting for regulatory and governance structures.

The influence of shadow economy, environmental policies and geopolitical risk on renewable energy: A comparison of high- and middle-income countries.

Given the alarming rate of climate change and environmental degradation, major countries are seeking ways to curtail environmental damage and attain sustainability in the future. In the quest for a green economy, countries are motivated to adopt renewable energy that can assist in resource conservation and efficiency. Accordingly, this study examines the diverse effects of the underground economy, environmental policy strictness, geopolitical risk, gross domestic product, carbon emissions, population, and oil prices on renewable energy for 30 high- and middle-income countries from 1990 to 2018. The empirical outcomes based on quantile regression document significant variations across two country groups. For instance, for high-income countries, the shadow economy has a detrimental effect across all quantiles but it is statistically significant at the top quantiles. Nonetheless, the effect of the shadow economy on renewable energy is detrimental and significant statistically across all quantiles for middle-income countries. In the context of environmental policy stringency, the effect is positive across both country groups, though there is heterogeneity in outcomes. Geopolitical risk has a positive influence on the deployment of renewable energy for high-income countries but negatively impacts renewables for middle-income countries. As far as policy suggestions are concerned, the policymakers of both high- and middle-income countries need to take steps to constrain the growth of the shadow economy by adopting effective policy strategies. Policies need to be implemented for middle income-countries to reduce the unfavorable effect of geopolitical uncertainty. The findings of this study contribute to a better and more precise understanding of factors shaping the role of renewables whereby the energy crisis would be mitigated.

Informal E-Waste Flows in Montréal: Implications for Extended Producer Responsibility and Circularity.

Environmental agencies around the world have adopted policies to manage e-waste and reduce the negative environmental impacts associated with its collection, sorting, dismantling, and recycling. In many OECD countries, where adequate policies and processing technologies exist, those who manage extended producer responsibility programs claim performance challenges due to competition from various actors collecting and managing e-waste "under the radar". While the material and economic losses attributed to such informal activities have been estimated by previous research, a detailed understanding of who is involved in these activities, why and how they operate, and with what social and environmental impacts, is often lacking. Our research offers an in-depth investigation into Montréal's informal e-waste flows. Whereas e-waste research and advocacy posit a dichotomy between "formal" and "informal" e-waste flows, our research reveals a more nuanced situation, with no water-tight separation between these flows. Formal and informal flows are often blurred, and change over time; and many actors are involved in both formal and informal activities. We reveal mechanisms whereby actors inadvertently contribute to informal activities because of inadequate incentives, limited program scope, reuse, parts harvesting, and documentation issues. This nuanced understanding helps identify policy loopholes, program shortcomings, and strategies for more sustainable e-waste flows, taking account of more ambitious circularity objectives and a just transition.

"Leave us alone": 'right to the city' of street vendors along Main North 1 Road, Maseru, Lesotho.

This article explores the lived daily experiences of street vendors operating along the Main North 1 Road in the CBD of Maseru, Lesotho. This exploration considers how street vendors access and negotiate a claim for the right to the street. The challenges confronting these vendors in their daily hustling, including COVID-19 restrictions, are also examined. A narrative inquiry research design informs this article with data collected from interviews with purposively selected street vendors from Maseru. This primary data was triangulated with document analysis to increase the validity of the findings. The findings highlight strategies employed by vendors in Maseru that include integrating with the formal enterprises, diversifying their trades, resisting and frustrating certain decisions by the local authorities, and contributing to urban blight. A framework for interrogating and understanding street vending and its nuances is postulated based on the findings from Maseru. The article strongly appeals to the authorities to find more benign ways of integrating street vending into the production of cities.

How well-targeted are payroll tax cuts as a response to COVID-19? evidence from China.

Numerous countries cut payroll taxes in response to COVID-19, including China, which reduced employer contributions by up to 21 percentage points. We use administrative data on more than 800,000 Chinese firms to evaluate payroll tax cuts as a business relief measure. We estimate that the tax cuts cover 31.5% of the decline in business cash flow, but labor informality causes 53% of registered firms-24% of aggregate economic activity-to receive no benefits at all. We quantify the targeting of the policy in terms of how much benefits flow to small firms less able to access external finance and to sectors worse hit by COVID-19. We find that (1) small firms and vulnerable industries are comparatively more labor intensive, which leads to desirable targeting; (2) labor informality worsens, but does not eliminate, targeting by firm size; and (3) labor informality is uncorrelated with the COVID-19 shock, and therefore does not affect targeting by sector.

How does Covid-19 affect urban slums? Evidence from settlement leaders in India.

Slum settlements have received significant attention for their vulnerabilities to the spread of Covid-19. To mitigate risks of transmission, and alleviate economic distress associated with containment measures, public health experts and international agencies are calling for community-driven solutions that harness local participation. In slum settlements, such approaches will encounter the informal slum leaders present across cities of the Global South. How are slum leaders positioned to address the health and livelihood threats of the pandemic within their neighborhoods? What problem-solving activities, if any, have they performed for residents during the pandemic? What factors shape success in those efforts? To answer these questions, we conducted a phone survey of 321 slum leaders across 79 slum settlements in two north Indian cities. The survey was conducted in April and May 2020, at the height of India's stringent national lockdown in response to the virus. Our survey reveals striking continuities with pre-pandemic politics. First, slum leaders persist in their problem-solving roles, even as they shift their efforts towards requesting urgently needed government relief (particularly food rations). Second, slum leaders vary in their reported ability to gather information about relief schemes, make claims, and command government responsiveness. The factors that inform the effectiveness of slum leaders during 'normal times', notably their education and degree of embeddedness in party networks, continue to do so during the lockdown. Slum leader reliance on partisan networks raises concerns regarding the inclusiveness of their efforts. Finally, slums are not uniformly challenged in maintaining social distancing. Pre-pandemic disparities in infrastructural development fragment the degree to which residents must depart from social distancing guidelines to secure essential services.

Informal professionalization of healthy participants in phase I clinical trials in Russia.

BACKGROUND: Previous social science research has shown how some healthy phase I trial participants identify themselves as workers and rely on trials as a major source of income. The term "professionalization" has been used to denote this phenomenon. PURPOSE: We aim to examine a component of healthy trial participants' professionalization that has not yet been systematically studied: how repeat phase I trial participants develop and claim expertise that distinguishes them from others and makes them uniquely positioned to perform high-quality clinical trial labor. We also aim to explain the significance of these research results for protection of healthy participants in phase I trials. METHODS: This qualitative exploratory study was conducted in Russia, in two phase I trial units. It involved semi-structured interviews with 28 healthy trial participants with varying lengths of experience in trials, observations of work done in trial units, and interpretive conversations with investigative staff. RESULTS: Interviewed healthy individuals who repeatedly participate in phase I trials describe developing knowledge and skills that involve appreciating the meaning of trial procedures, coming up with techniques to efficiently follow them, organizing themselves and others in the course of a trial, and sharing tacit ways of doing trial work well with other less experienced participants. Our results suggest that a prerequisite for such expertise-centered professionalization is the emergence of a positive identity linked to seeing value in trial participation work. A crucial component of professionalization thus understood is the development of a work ethic that entails caring about results and being reliable partners for investigators. LIMITATIONS: The attitudes and behaviors presented in this article are not suggested to be universally shared among healthy trial participants, but rather represent a particular instance of professionalization that coexists with other views and tactics. CONCLUSIONS: A way of better protecting healthy trial participants begins with recognizing their skills, knowledge, and the centrality of the contribution they are making to pharmaceutical research. Currently, the expertise of experienced trial participants is recognized on the work floor only; therefore, the professionalization we described is informal. Yet, the informal professionalization process is inherently risky as it does not involve any change in the formal conditions of trial participants' work. Instituting formal measures for protecting healthy trial participants as skilled workers combined with recognition of their expertise is essential.

Urban informality as a signifier: Performing urban reordering in suburban Rio de Janeiro.

Urban informality is typically ascribed to the urban poor in cities of the Global South. Drawing on Judith Butler's concept of performativity and taking the case of Rio de Janeiro in the context of the 2016 Olympic Games, this article conceptualizes informality as a signifier and a procedural, relational category. Specifically, it shows how different class actors have employed the signifier informality (1) to legitimize the confinement of marginalized populations; (2) to justify the organized efforts of the upper middle class to protect their 'self-enclosed' gated communities; and (3) to warrant the formation of opposition and alliances between inhabitants, activists, and researchers on the edges of the urban order. This article offers new perspectives to better understand the relationship between informality and confinement by examining the active role that inhabitants of marginalized settlements assume in the Olympic City.

L'informalité urbaine est traditionnellement associée aux populations pauvres des villes du Sud global. À partir du concept de performativité de Judith Butler et du cas particulier de Rio de Janeiro dans le contexte des jeux Olympiques de 2016, nous nous attachons dans cet article à conceptualiser l'informalité comme un signifiant et une catégorie relationnelle procédurale. Plus précisément, nous montrons comment des acteurs de différentes classes sociales ont pu employer le signifiant « informalité ¼ pour (1) légitimer le confinement des populations marginalisées ; (2) justifier les efforts concertés de la classe moyenne supérieure pour protéger leurs résidences sécurisées refermées sur elles-mêmes ; et (3) justifier la formation de conflits et d'alliances entre habitants, activistes et chercheurs autour de l'ordre urbain. Cet article offre de nouveaux éclairages pour mieux comprendre le rapport entre informalité et confinement en examinant le rôle actif que les habitants des quartiers marginalisés ont joué dans la ville olympique.

La informalidad urbana suele atribuirse a los individuos pobres que residen en las ciudades del Sur global. Basándose en el concepto de performatividad de Judith Butler y tomando el caso de Río de Janeiro en el contexto de los Juegos Olímpicos de 2016, este artículo conceptualiza la informalidad como un significante y una categoría procedimental y relacional. Específicamente, muestra cómo actores de diferentes clases sociales han empleado el significante de informalidad para (1) legitimar el confinamiento de las poblaciones marginadas; (2) justificar los esfuerzos organizados de la clase media alta para proteger sus comunidades "cerradas" en urbanizaciones; y (3) justificar la formación de conflictos y alianzas entre habitantes, activistas e investigadores en torno al orden urbano. Este artículo ofrece nuevas perspectivas para entender mejor la relación entre informalidad y confinamiento examinando el papel activo que asumen los habitantes de asentamientos marginados en la Ciudad Olímpica.

Serenity: Violence, Inequality, and Recovery on the Edge of Mexico City.

Over the last decade, there has been a sharp increase in drug addiction in Mexico, especially among the urban poor. During the same period, unregulated residential treatment centers for addiction, known as anexos, have proliferated throughout the country. These centers are utilized and run by marginalized populations and are widely known to engage in physical violence. Based on long-term ethnographic research in Mexico City, this article describes why anexos emerged, how they work, and what their prevalence and practices reveal about the nature of recovery in a context where poverty, drugs, and violence are existential realities. Drawing attention to the dynamic relationship between violence and recovery, pain, and healing, it complicates categories of violence and care that are presumed to have exclusive meaning, illuminating the divergent meanings of, and opportunities for, recovery, and how these are socially configured and sustained.

Household livelihood resilience of pastoralists and smallholders to climate change in Western Himalaya, India.

Smallholders and pastoralists are particularly vulnerable to the impacts of climate change due to their high reliance on socio-ecological systems for their livelihood. Building their resilience to these adverse effects of climate change is crucial for mitigating their vulnerabilities, especially in remote and fragile ecosystems. This study aims to assess the climate change livelihood resilience of smallholders and pastoralists in the Indian Himalayas. We build a livelihood resilience index, using the three dimensions of resilience, namely assimilative capacity, autopoiesis and cognitive ability, and weighed using entropy-TOPSIS approach The dimensions of resilience was estimated through indicators by a household survey of 289 randomly selected respondents across the three districts of Garhwal Himalayas. The results showed that the livelihood resilience of smallholders was greater than pastoralists. Among pastoralists, settlement brought positive changes to their livelihood, opening the gateway to access basic facilities. Key findings of the study indicate that public policy should focus towards information accessibility, encouraging environmental awareness and conservation, promoting social inclusion and cooperatives, and fostering grass root organization structures like forest-level organisation through informality to strengthen the resilience of communities to climate change.

The Formal and the Informal in the History of Socialist Scholarly Interconnectedness in East Central Europe.

With the emergence of Olympic internationalism, scholarly networking in East Central Europe came to be dominated by the idea of scholars representing their nations, which replaced the previously leading pattern of private elite scholars with extensive international contacts. This also formalised trans-border contacts, which became increasingly seen as international. In this article, we trace the relationship between these formal and informal networks from the late 19th century to the end of the socialist period, showing that even as formalisation grew, it depended heavily on a variety of informal connections. Even during the period of socialism, when the state sought to control international exchange, scholars used informality to circumvent politically determined constraints. Nevertheless, these informal contacts were not outside the system, but were an integral part of it and depended on formal preconditions. Concentrating on Czechoslovak-Polish relations we argue that in addressing the issue of the relationship between the formal and the informal, a combination of sources must be used, which should then be scrutinised for the stories their authors wish to tell. While archival sources are used for the formal part, oral histories or memoirs reveal the informal part. In East Central Europe, formal sources are likely to ignore informality, especially when it was associated with illegality, whereas ego-documents, especially those produced after 1989, are likely to ignore or downplay connections to the state and overemphasise informality as a means of acting outside politics. Thus, writing the history of informality in socialist scholarship, not only in terms of international contacts but also in terms of everyday practices, is a way of developing counter-narratives to the state-centeredness of current research, which must be linked to a critical study of the contemporary memory of socialist scholarship that shapes the narratives told in oral history.

Reclaiming Placemaking for an Alternative Politics of Legitimacy and Community in Homelessness.

This study is about the struggle for legitimacy in place among a group of people often assumed to have neither. It examines the roll of informal placemaking and community building in struggles for settlement among people experiencing homelessness. It does so through ethnographic observation, photo-documentation, and participatory action research at three sites in Oakland, California, on which unhoused people (and some housed members of the surrounding community) have demonstrated bold forms of grassroots placemaking on public land. The first site, which came to be known as Housing and Dignity Village, was a small intentionally organized community of unhoused women and families that existed for 41 politically charged days in a low-income residential neighborhood before being cleared by authorities in 2018. The second, a highly visible piece of desirable city-owned land, has been occupied by unhoused people to varying degrees since 2016 while being considered for various housing development proposals. The third is the Wood Street Encampment, Oakland's largest encampment and one of its longest standing, which has survived numerous partial evictions and a web of jurisdictional authority to become home to an extensive and innovative informal community-building effort. Despite their differences, each offers a powerful case of place-based bottom-up community organizing among unhoused people, in which placemaking becomes part of a subtle politics of visibility, being, and legitimacy. The study argues that these instances and others not only demonstrate a different sort of placemaking, but demand that we reconsider and reclaim the concept itself.

Short-term labour transitions and informality during the COVID-19 pandemic in Latin America.

Latin America was one of the regions hardest hit by the COVID-19 pandemic. This paper analyses, from a dynamic and comparative perspective, labour transitions triggered by the pandemic in six Latin American countries: Argentina, Brazil, Costa Rica, Mexico, Paraguay, and Peru. Special attention is paid to transits around labour informality during this period. Unlike previous crises, the fall in informal occupations deepened the overall contraction in employment. This was explained by a significant increase in exit rates from these jobs and, to a lesser extent, by reductions in entry rates. Most of the informal workers who lost their jobs left the labour force. Contrary to this labour movement, transits from informal to formal jobs significantly dropped during the most critical phase in this crisis. Partial recovery in employment since mid-2020 has been led by an increase in informal jobs. The labour dynamic has been different between men and women. This study reveals the relevance of dynamic analysis to clearly identify labour transitions that occurred during a labour crisis of unprecedented intensity and characteristics in Latin America.

Debates Paper: COVID-19 and urban informality: Exploring the implications of the pandemic for the politics of planning and inequality.

The COVID-19 pandemic has highlighted a major contradiction in contemporary urban planning. This is the relationship between the entrepreneurial modes of urban politics that shape contemporary planning practice and the interrelated dynamics of economic precarity and informalisation of low-income communities that exacerbate contagion, and therefore enable pandemic spread. Through a review of literature on the urban dimensions of COVID-19, and on the historical relationship between pandemics and urban planning, we develop a framework for analysing the debates that are emerging around planning approaches to addressing contemporary pandemic risk in low-income, informalised communities. We argue that post-pandemic debates about urban planning responses are likely to take shape around three discourses that have framed approaches to addressing informalised communities under entrepreneurial urbanism - a revanchist approach based on territorial stigmatisation of spaces of the poor, an incrementalist approach premised on addressing the most immediate drivers of contagion, and a reformist approach that seeks to address the structural conditions that have produced economic precarity and shelter informality. We further argue that any effort to assess the political outfall of the COVID-19 pandemic in a given context needs to take an inter-scalar approach, analysing how debates over informality take shape at the urban and national scales.

Informality, economic complexity, and internalization of rules.

This research aimed to find out the relationship between informality and the internalization of the rules of behavior required for complexity in the economic system, as better knowledge is required for formalization policy to have a greater impact. We use the economic complexity index (ECI) for 2018 at the regional level in Colombia, which combines the country's productive structure with the amount of knowledge and know-how embodied in the goods it produces. The informality measure we use is the individual's affiliation to social security (in particular health insurance), and we use a proxy of civic rule's internalization as an inverse relation with traffic tickets. This research aimed to shed new light on public policy to improve formalization and its economic impact. First, we include a theory that includes both intrinsic and extrinsic motivation types. The self-determination theory or organismic integration theory proposes this theory. Second, we have argued that the motivation to formalize is intrinsic to greater cultural capacity. Individuals gradually internalize rules of behavior that have repercussions on social dynamics. Third, the composition and characteristics of the families in the study sample seem to show that some factors increase the propensity for informality. Our empirical analysis reveals that group of people with a lower educational level are the ones who are more likely to belong to the informal labor market. These results are consistent with the literature. Multivariate Probit regression was used to examine these factors.

Are livelihoods of slum dwellers sustainable and secure in developing economies? Evidences from Lucknow, Uttar Pradesh in India.

Objectives: We adopted the Sustainable Livelihood Security (SLS) approach to assess the living conditions of slum dwellers in Lucknow, Uttar Pradesh, India. Keeping the urban poor at the centre, we attempted to bring out the multidimensional nature of poverty and explored various aspects of the livelihood of slum dwellers. Methods: We surveyed 900 households from both notified and non-notified slums of Lucknow city to construct the SLS index, keeping the social, economic, infrastructural, health, and micro-environmental aspects of slum dwellers in the background. We collected data based on the household approach of the UN and the neighbourhood approach of the Government of India and aggregated the weighted index values under various sub-components to construct a composite index. Results: The results suggested that the index values were low for both types of slum dwellers in Lucknow city specifically in the economic, infrastructural, and micro-environmental aspects. The results also showed that 'non-notified slum dwellers' were much more deficient in all the dimensions compared to their 'notified' counterparts. The livelihood condition of the marginalized households (backward castes and minorities) was especially precarious and vulnerable. Conclusion: The findings reveal the existence of a high level of informality of livelihood of the urban poor in terms of housing, employment, health, and other basic amenities, and demonstrate that their livelihood condition is characterized by a low assets base, and poor strategies to overcome exigencies and risks. Recommendations: This paper recommends enactment of an urban employment guarantee act, conducting of sabhas (meetings) at the ward level on a regular basis to promote awareness, and notification of non-notified slums to notified slums on regular basis for the overall development of slum dwellers.

Renewable and nonrenewable energy consumption, economic growth, and CO2 emissions in Eastern and South African countries: the role of informality.

This study investigates the role of informality in the relationship among renewable and nonrenewable energy consumption, economic growth, and CO2 emissions in a panel of 19 Eastern and South African countries. The empirical strategy exploits the panel generalized method of moments, panel fixed effects models using the Driscoll-Kraay standard errors, panel method of moments quantile regressions, and the Dumitrescu-Hurlin bootstrap panel Granger causality analysis. The results are fourfold. First, nonrenewable energy consumption is positively associated with CO2 emissions, while renewable energy consumption is not. Second, there is a nonlinear ∩ -shaped relationship between economic growth and CO2 emissions, consistent with the environmental Kuznets curve (EKC) hypothesis. Third, the results show a nonlinear ∪ -shaped relationship between informality and CO2 emissions, suggesting that higher informality is associated with lower CO2 emissions up to a certain critical point beyond which further increases in informality precipitate higher CO2 emissions. Fourth, the results show unidirectional causality from CO2 emissions to renewable energy, from CO2 emissions to nonrenewable energy, from informality to CO2 emissions, and feedback causality between GDP growth and CO2 emissions.

Uncovering commercial activity in informal cities.

Knowledge of the spatial organization of economic activity within a city is a key to policy concerns. However, in developing cities with high levels of informality, this information is often unavailable. Recent progress in machine learning together with the availability of street imagery offers an affordable and easily automated solution. Here, we propose an algorithm that can detect what we call visible establishments using street view imagery. By using Medellín, Colombia as a case study, we illustrate how this approach can be used to uncover previously unseen economic activity. By applying spatial analysis to our dataset, we detect a polycentric structure with five distinct clusters located in both the established centre and peripheral areas. Comparing the density of visible establishments with that of registered firms, we infer that informal activity concentrates in poor but densely populated areas. Our findings highlight the large gap between what is captured in official data and the reality on the ground.

Examining the Planning Policies of Urban Villages Guided by China's New-Type Urbanization: A Case Study of Hangzhou City.

Planning policies have greatly influenced the development of urban villages, an informal phenomenon in which rural settlements are encircled by urban environments during China's rapid urbanization process. "The National New-type Urbanization Plan (2014-2020)" of China initiated in 2014 provides a new perspective on planning policy research on China' urban villages. Hangzhou, a pioneer city that adopts new-type urbanization in China and combines the characteristics of rapid urban growth, mountainous urban terrains, and a long cultural history, serves as a typical case study to compare the planning policies responding to the informality of urban villages guided by traditional and new-type urbanization. This study employed the content analysis method to analyze the evolution of Hangzhou's planning policies of urban villages since the reform and opening up and used one-way ANOVA to analyze the differences in rental levels among the urban villages developed under the planning policies of different urbanization stages, aiming to compare the influences of planning policies guided by traditional and new-type urbanization on urban village development. The results indicate that the policies allowing some degree of informality in the new-type urbanization stage achieve a higher rental level for urban villages than the policies of the traditional urbanization stages that restrict and prevent informality. The findings of this research suggest that informality may provide advantages that formality cannot replace and provides important policy implications for rapidly urbanizing countries.
