Interesting academic articles for November 2019

Here’s what I’ve been looking forward to reading lately.

Sam Hickey, Tom Lavers, Jeremy Seekings, and Miguel Niño-Zarazúa, eds.  2019. The Politics of Social Protection in Eastern and Southern Africa.  UNU-WIDER.

The Politics of Social Protection in Eastern and Southern Africa challenges the common conception that [social protection] has been entirely driven by international development agencies, instead focusing on the critical role of political dynamics within specific African countries. It details how the power and politics at multiple levels of governance shapes the extent to which political elites are committed to social protection, the form that this commitment takes, and the implications that this has for future welfare regimes and state-citizen relations in Africa. It reveals how international pressures only take hold when they become aligned with the incentives and ideas of ruling elites in particular contexts. It shows how elections, the politics of clientelism, political ideologies, and elite perceptions all play powerful roles in shaping when countries adopt social protection and at what levels, which groups receive benefits, and how programmes are delivered.

Rumman Khan, Oliver Morrissey, and Paul Mosley.  2019.  “Two Africas? Why Africa’s ‘growth miracle’ has barely reduced poverty.”  RePEc discussions papers 2019 – 08.

Growth improved substantially in most countries in sub-Saharan Africa (SSA) since 1990, but poverty in SSA as a whole has fallen by about a third, compared to by half or more in other developing regions. While some countries have had little or no success in reducing poverty, many have had significant achievements. The paper argues that inter-country differences, traceable to colonial experience, are crucial to understanding this varied SSA performance. This is based on a distinction between relatively labour-intensive ‘smallholder’ colonial economies and capital-intensive ‘extractive economies’ exporting minerals and plantation crops. Because of the more equitable income distribution and African political inclusion generated in smallholder economies, at independence they were in a better position than extractive economies to translate growth into poverty reduction. Since the 1990s (when poverty data are available) the distinction in terms of poverty reduction can be observed. The empirical analysis estimates the growth elasticity of poverty using various specifications, some including inequality. There are two key robust findings: i) smallholder economies significantly outperform extractive economies in poverty reduction; and ii) growth rates do not differ on average between the two groups, but the growth elasticity of poverty is higher in smallholder economies.

Michael Clemens, Helen Dempster, and Kate Gough.  2019.  “Promoting New Kinds of Legal Labour Migration Pathways Between Europe and Africa.”  Center for Global Development.

As Europe’s working-age population continues to decline, sub-Saharan Africa’s is rapidly increasing. Many of these new labour market entrants will seek opportunities in Europe, plugging skill gaps and contributing to economies in their countries of destination. To make the most of these movements, the new European Commission should create and promote new kinds of legal labour migration pathways with more tangible benefits to countries of origin and destination; pilot and scale Global Skill Partnership projects between Europe and sub-Saharan Africa and within Africa; and be a positive voice for migration within Europe, promoting the benefits from migration and ensuring they are understood.

Sohela Nazneen.  2019.  “How Do Leaders Collectively Influence Institutions?”  Developmental Leadership Program.  

How do leaders collectively influence institutions? This question lies at the heart of understanding how actors influence positive change. Social scientists have attempted to answer it from different perspectives. Broadly, these either emphasise the role of actors (both the individual leader and collective bodies) and how they act and what strategies they use, or focus more on how structures and institutions (i.e. rules of the game) define contextual boundaries and create specific opportunities and incentives for actors to behave in specific ways. These two perspectives reveal important aspects of how and why actors engage in collective processes of change. However … unpacking how leaders and coalitions engage in collective processes of change requires a deeper and nuanced understanding of what factors and conditions influence the decisions taken and strategies used by leaders and coalitions at different stages along the lifecycle of reform. Collective processes of change have three interlinked stages: 1) collective formation—when leaders focus on forming collectives and maintaining group cohesion; 2) legitimation—when leaders and coalitions are concerned with framing and justifying their demands and strengthening their position to make claims; and 3) securing institutional change—when the focus is on using different strategies to negotiate an outcome for the constituencies they claim to represent.

Rajeev Dehejia, Cristian Pop-Eleches, and Cyrus Samii.  2019.  “From Local to Global: External Validity in a Fertility Natural Experiment.”  NBER working paper 21459.

We study issues related to external validity for treatment effects using over 100 replications of the Angrist and Evans (1998) natural experiment on the effects of sibling sex composition on fertility and labor supply. The replications are based on census data from around the world going back to 1960. We decompose sources of error in predicting treatment effects in external contexts in terms of macro and micro sources of variation. In our empirical setting, we find that macro covariates dominate over micro covariates for reducing errors in predicting treatments, an issue that past studies of external validity have been unable to evaluate. We develop methods for two applications to evidence-based decision-making, including determining where to locate an experiment and whether policy-makers should commission new experiments or rely on an existing evidence base for making a policy decision.

Caitlin Tulloch.  2019.  “Taking intervention costs seriously: a new, old toolbox for inference about costs.”  Journal of Development Effectiveness.

This paper examines a new set of average cost data from a large international NGO, finding that costs for the same intervention can vary as much as twenty times when scale or context is changed. Despite this challenge to the generalisability of cost estimates, a high proportion of the variation can be explained by observable program and contextual characteristics. Binary questions about whether cost estimates are externally valid do not provide a useful framework for wider inference; instead, researchers can gain analytical traction if they study what factors cause the costs of specific interventions to change, and by how much.
