Language of instruction in schools in low- and middle-income countries: A systematic review.

Based on the theory of change, we gather, organize, and synthesize the evidence on the impact of three language of instruction (LOI) choices (teaching in mother tongue [MT] with later transition, teaching in a non-MT language, or teaching in two or more languages at one time) on literacy and biliteracy outcomes. We focus on quantitative and qualitative studies of LOI interventions in low- and middle-income countries (LMICs) and consider languages that are commonly spoken in the developing world. As such, we include studies that examine transfers from local languages to English, but not those evaluating transfers from local languages to languages that are less spoken in LMICs (e.

Women's groups, covariate shocks, and resilience: An evidence synthesis of past shocks to inform a response to COVID-19.

Interventions with women's groups are increasingly seen as an important strategy for advancing women's empowerment, health, and economic outcomes in low- and middle-income countries, with the potential to increase the resiliency of members and their communities during widespread covariate shocks, such as coronavirus disease 2019 (COVID-19). This evidence synthesis compiles evidence from past shocks on women's group activities and the extent to which women's groups mitigate the effects of shocks on members and communities. We reviewed 90 documents from academic databases, organizational reports, and additional gray literature, and included literature diverse in geography, type of women's group, and shock.

Intraclass Correlations Values in International Development: Evidence Across Commonly Studied Domains in sub-Saharan Africa.

The sharp increase in the number of experimental studies evaluating development programs raises the need for accurate intraclass correlations (ICC) to conduct power calculations so that researchers can design studies to detect meaningful effects with sufficient statistical power. The intraclass correlation is an important parameter for determining the statistical power of cluster-randomized trials. The parameter is rarely available to researchers planning a study until after the design is set and data are already collected.

Women's groups and COVID-19: An evidence review on savings groups in Africa.

The coronavirus disease 2019 (COVID-19) pandemic and some of the associated policy responses have resulted in significant gendered impacts that may reverse recent progress in gender equality, including in sub-Saharan Africa. This paper presents emerging evidence from studies in diverse contexts in sub-Saharan Africa -with a deep dive into Nigeria and Uganda-on how COVID-19 has affected women's groups, especially savings groups, and how these groups have helped mitigate the gendered effects of the pandemic's and the associated policy responses' consequences up until April 2021. The synthesis presents evidence that savings groups found ways to continue operating, provided leadership opportunities for women during the pandemic, and mitigated some of the negative economic consequences of COVID-19 on individual savings group members.

Economies of scale of large-scale international development interventions: Evidence from self-help groups in India.

Livelihoods and microfinance programs for women often show reduced impacts after scale-up. Yet, program scale-up may reduce average per capita costs and maintain cost-effectiveness despite lower impact. This paper presents evidence on the association between program scale, costs, and cost-effectiveness by analyzing how the costs of a large-scale Self-Help Group (SHG) program in India changed from its inception in 2007 to its scale-up in 2019.

Effects of integrated economic and health interventions with women's groups on health-related knowledge, behaviours and outcomes in low-income and middle-income countries: a systematic review protocol.

Introduction: Economic groups, such as microfinance or self-help groups are widely implemented in low-income and middle-income countries (LMICs). Women's groups are voluntary groups, which aim to improve the well-being of members through activities, such as joint savings, credit, livelihoods development and/or health activities. Health interventions are increasingly added on to existing women's economic groups as a public health intervention for women and their families.

A perverse 'net' effect? Health insurance and ex-ante moral hazard in Ghana.

Incentive problems in insurance markets are well-established in economic theory. One of these incentive problems is related to reduced prevention efforts following insurance coverage (ex-ante moral hazard). This prediction is yet to be tested empirically with regard to health insurance, as the health domain is often considered relatively immune to perverse incentives, despite its validation in other insurance markets that entail adverse shocks.

Equity aspects of the National Health Insurance Scheme in Ghana: Who is enrolling, who is not and why?

To improve equity in the provision of health care and provide risk protection to poor households, low-income countries are increasingly moving to social health insurance. Using data from a household survey of 3301 households conducted in 2009 this study aims to evaluate equity in enrollment in the National Health Insurance Scheme (NHIS) in Ghana and assess determinants of demand across socio-economic groups. Specifically by looking at how different predisposing (age, gender, education, occupation, family size, marital status, peer pressure and health beliefs etc) enabling (income, place of residence) need (health status) and social factors (perceptions) affect household decision to enrol and remain in the NHIS.

Insuring against earthquakes: simulating the cost-effectiveness of disaster preparedness.

Ex-ante measures to improve risk preparedness for natural disasters are generally considered to be more effective than ex-post measures. Nevertheless, most resources are allocated after an event in geographical areas that are vulnerable to natural disasters. This paper analyses the cost-effectiveness of ex-ante adaptation measures in the wake of earthquakes and provides an assessment of the future role of private and public agencies in disaster risk management.
