Working Paper CEsA no. 198/2024 sheds light on the concept of cumulative causation and its relevance for explaining economic growth trajectories in Sub-Saharan Africa
CEsA has published the Working Paper no 198/2024, entitled “The Relevance of the Concept of Cumulative Causation: Understanding growth trajectories in Sub-Saharan Africa”, in English, authored by Alice Nicole Sindzingre. Professor Sindzingre is a CEsA researcher, Research Associate at the CEPN (Paris-North Economics Centre, University Paris-North, France), and at the LAM Research Centre (‘Africas in the World’, National Centre for Scientific Research/CNRS-SciencesPo-Bordeaux, France).
This Working Paper sheds light on the concept of cumulative causation and its relevance for explaining economic growth trajectories in Sub-Saharan Africa. Firstly, it empirically discusses the possibility of divergence between regions and countries, as well as the related theoretical debates. Secondly, it questions the mainstream explanations of growth trajectories: notably the limitations stemming from the pre-eminence of the conceptual framework of equilibrium, as well as the limitations of modelling in the apprehending of causation and consideration of other social sciences. Then it presents the concept of cumulative causation. Finally, it shows the relevance of this concept for the explanation of growth trajectories via the stylised examples of Sub-Saharan Africa vs. East Asian economies.

Abstract:
Differences in growth trajectories among countries – including the possibility of divergence –, are a central issue in economics. Mainstream economics explain growth processes via varieties of neoclassical models, even improved with concepts such as institutions. Yet such models have difficulties in providing accurate accounts of the growth trajectories of many developing countries, notably low-income ones. It is argued that the growth paths of low-income countries are more appropriately explained by the theoretical framework that relies on the nexus of concepts of cumulative causation, non-linearities, threshold effects, self-reinforcing processes, irreversibility, path dependence and traps – though this approach remains marginal in mainstream economic analyses of growth and development. Firstly, this nexus of concepts is a powerful framework concerning the possibility and explanation of dynamic divergence regarding growth between countries, as it exhibits properties such as: the possibility of cumulative, dynamically self-reinforcing, processes; the existence of thresholds and tipping points; multiple equilibria. Secondly, cumulative causation, by definition, involves a combination of causes: its conceptual framework allows for the integration of several dimensions – economic, political, social, cognitive –, whose combination results in either virtuous or vicious circles. In developing countries, these causes (and their coalescence) typically consist in economic structures (e.g., commodity-based export markets), political institutions and social norms (predatory regimes, high inequality) as well as types of public policies.

Working Paper 199/2024: Literatura e Ecologia: Representações da água em romances angolanos e moçambicanos
Abstract:
This article offers a brief cartography of the narrative role of water in Angolan and Mozambican literature, through a comparative reading of four novels: O desejo de Kianda (1995) by the Angolan Pepetela; De Rios Velhos e Guerrilheiros. I. O Livro dos Rios (2006) by Luandino Vieira; Água. Uma novela rural (2016) and Ponta Gea (2017) both by the Mozambican João Paulo Borges Coelho.
The introduction places the proposed cartography within the framework of ecocritical studies, whose various paradigms offer useful tools and concepts for reading the selected literary works. The thematic and comparative methodological approach highlights experiences and imaginaries common to two post-colonial contexts, despite the difference in scenarios, themes, aesthetic choices and narrative strategies. The analysis aims to demonstrate that water is a crucial element in narrating post-colonial Angolan and Mozambican societies.

Why are some countries so rich while others so poor? I argue that thousands of years of farming practice has independent and long-lasting effect on the wealth of nations today. For the whole world sample, I show that rice farming is negatively associated with economic development, independent of the effects of geography and institution. However, the case of China presents a puzzle. Empirical results using disaggregated county-level data suggest a different pattern. I discuss the potential channels of the long-lasting effect, the China puzzle and implications for China’s long-term growth.

Working Paper CEsA no. 197/2024 analyses the impact of work and income on the identity of women horticulturists in Guinea-Bissau
CEsA has published its firts Working Paper in 2024 (no 197/2024), entitled “La Production Agricole des Femmes en Guiné-Bissau comme Moyen d´Afirmation de son Identité”, in French, authored by Carlos Sangreman and Mara Melo. Sangreman is President of the CEsA Assembly, is a CESA researcher, assistant professor of the Universidade de Aveiro (Portugal), and consultant for Guinea-Bissau at the Institute of Hygiene and Tropical Medicine in Portugal and Casa dos Direitos in Bissau. Melo holds a master’s degree from the University of Coimbra and the Institut d’ Études Polítques de Bordeaux.
This Working Paper is an intermediate product of the study carried out for Swiss Cooperation in Guinea-Bissau. Surveys and interviews were carried out in the regions of Bissau, Biombo, Bafatá and Oio, in the areas of production of leguminous agricultural products, by producers (mostly women). The focus of the analysis is on the practice of horticulture with the income belonging to women: “it influences the economic factor through the production and sales activity, it influences cultural factors because it is the woman who makes the key decisions for the activity and not the man and fights against family discrimination because women take on responsibilities in the family and home that they otherwise would not be able to assume and, therefore, tend to have a greater voice in family decisions”.

Abstract:
This working paper is an intermediate product of the study done for Swiss Cooperation in Guinea-Bissau, written in French without any point in Portuguese. What we demonstrate, as well as the principles of restitution and appropriation by the persons or institutions that access to respond to surveys or interviews, are words that do not translate into concrete actions for this Cooperation. The data were obtained by surveys and interviews in the regions of Bissau, Biombo, Bafatá, and Oio, with the producers (which also include a limited number of male producers) of leguminous agricultural products, in a sample of 160 people chosen at random. At the option of the promoter, the study focused on the marketing of products and not on production. To better understand the results, it must be said that this business model is not very profitable, but it is an activity that gives a greater independence of women in relation to men in the family space, since decisions about the use of profits belong to the producers. It also has a potential environment of action for the affirmation of the social (and not just family) identity of women that should not be despised although, as far as we can see, this is expressed for now only in the organization of associations of producers.

Understanding Social Realities of Internally Displaced Persons (IDPs) in the Federal Capital Territory of Nigeria (FCT), Abuja
Abstract:
This article examines the social realities of forcibly displaced persons in Nigeria, with a focus on internally displaced persons (IDPs) in the Federal Capital Territory (FCT) of Nigeria, Abuja. Internally displaced persons are individuals who have been forced from their homes or habitual places of residence and, unlike refugees, have not crossed the borders of their country. They remain under the primary protection of their governments and often seek refuge in their own countries. This study draws on secondary data sources and primary data collected from two IDPs campsites, arguing that most IDPs in the FCT, displaced by the Boko Haram insurgency live in makeshift and inhumane informal settlements in the peri-urban areas of Abuja City. These settlements also host the urban poor and other economic migrants in the country’s capital, occasionally leading to conflicts between them. The paper calls for the government to recognise the presence and condition of IDPs in the FCT and to work with relevant organisations to provide durable solutions to ensure that displaced persons can once again become productive members of society.
