AbstractFrailty is a common syndrome affecting older adults. While frailty has well-established relationships with multiple adverse health outcomes and death, the role of the social and economic environment in the development of frailty is less clear. We consider this relationship in India, which has a growing population of older adults whose environments have undergone extensive social and economic changes over the last few decades. We compare the distributions of frailty among older adults across the states of India and explore the influence of both current social and economic indicators and historical indicators at the state level. We find substantial variation in the state-level prevalence of frailty, which remains even after sex stratification and age standardization. We also find significant associations between frailty and current (2018) and historic (1981) state-level socioeconomic variables. We conclude with a discussion of the scientific and policy implications of early-life and contemporaneous social and economic conditions for the frailty of older adults.

Given the scarcity of safe and effective COVID-19 vaccines, a chief policy question is how to allocate them among different sociodemographic groups. This paper evaluates COVID-19 vaccine prioritization strategies proposed to date, focusing on their stated goals; the mechanisms through which the selected allocations affect the course and burden of the pandemic; and the main epidemiological, economic, logistical, and political issues that arise when setting the prioritization strategy. The paper uses a simple, age-stratified susceptible–exposed–infectious–recovered model applied to the United States to quantitatively assess the performance of alternative prioritization strategies with respect to avoided deaths, avoided infections, and life-years gained. We demonstrate that prioritizing essential workers is a viable strategy for reducing the number of cases and years of life lost, while the largest reduction in deaths is achieved by prioritizing older adults in most scenarios, even if the vaccine is effective at blocking viral transmission. Uncertainty regarding this property and potential delays in dose delivery reinforce the call for prioritizing older adults. Additionally, we investigate the strength of the equity motive that would support an allocation strategy attaching absolute priority to essential workers for a vaccine that reduces infection-fatality risk.

AbstractWe analyse the economic consequences for poor countries of investing in female health within a unified growth model featuring health-related gender differences in productivity. Better female health accelerates the demographic transition and thereby the take-off towards sustained economic growth. By contrast, male health improvements delay the transition and take-off because they tend to raise fertility. However, households tend to prefer male health improvements over female health improvements because they imply a larger static utility gain. This highlights the existence of a dynamic trade-off between the short-run interests of households and long-run development goals.

Infectious diseases are now emerging or reemerging almost every year. This trend will continue because a number of factors, including the increased global population, aging, travel, urbanization, and climate change, favor the emergence, evolution, and spread of new pathogens. The approach used so far for emerging infectious diseases (EIDs) does not work from the technical point of view, and it is not sustainable. However, the advent of platform technologies offers vaccine manufacturers an opportunity to develop new vaccines faster and to reduce the investment to build manufacturing facilities, in addition to allowing for the possible streamlining of regulatory processes. The new technologies also make possible the rapid development of human monoclonal antibodies that could become a potent immediate response to an emergency. So far, several proposals to approach EIDs have been made independently by scientists, the private sector, national governments, and international organizations such as the World Health Organization (WHO). While each of them has merit, there is a need for a global governance that is capable of taking a strong leadership role and making it attractive to all partners to come to the same table and to coordinate the global approach.

We assess Africa's prospects for enjoying a demographic dividend. While fertility rates and dependency ratios in Africa remain high, they have started to decline. According to United Nations projections, they will fall further in the coming decades such that by the mid-21st century the ratio of the working-age to dependent population will be greater than in Asia, Europe, and Northern America. This projection suggests Africa has considerable potential to enjoy a demographic dividend. Whether and when it actually materializes, and also its magnitude, hinges on policies and institutions in key realms that include macroeconomic management, human capital, trade, governance, and labour and capital markets. Given strong complementarities among these areas, coordinated policies will likely be most effective in generating the momentum needed to pull Africa's economies out of a development trap.
