The impact of early-life access to oral polio vaccines on disability: evidence from India
We evaluate the impact of oral polio vaccines on the incidence of all disabilities (locomotor, hearing, visual, speech, and mental) in India, focusing on polio-related disability, which constitutes the largest fraction of locomotor disabilities. Polio was hyperendemic in India even as recently as the early 1990s, but the country was declared wild polio virus-free in 2014. Intent-to-treat effects from difference-in-differences with multiple time period models that condition on demographic and socio-economic characteristics reveal that access to oral polio vaccines in the year of birth reduced the incidence of any disability, locomotor disability, and polio-related disability by 20.5%, 11.6%, and 7.2%, respectively, signaling substantial gains. Impacts on any disability underline that polio vaccines had positive spillover effects on other disability categories as well. The eradication of polio in India, while relatively late, brought significant health benefits and is a notable health economics success story in a developing context.
期刊介绍:
The Journal of Population Economics is an international quarterly that publishes original theoretical and applied research in all areas of population economics.
Micro-level topics examine individual, household or family behavior, including household formation, marriage, divorce, fertility choices, education, labor supply, migration, health, risky behavior and aging. Macro-level investigations may address such issues as economic growth with exogenous or endogenous population evolution, population policy, savings and pensions, social security, housing, and health care.
The journal also features research into economic approaches to human biology, the relationship between population dynamics and public choice, and the impact of population on the distribution of income and wealth. Lastly, readers will find papers dealing with policy issues and development problems that are relevant to population issues.The journal is published in collaboration with POP at UNU-MERIT, the Global Labor Organization (GLO) and the European Society for Population Economics (ESPE).Officially cited as: J Popul Econ Factor (RePEc): 13.576 (July 2018) Rank 69 of 2102 journals listed in RePEc
