Effects of self-employment on hospitalizations: instrumental variables analysis of social security data

Abstract:

The importance of self-employment and small businesses raises questions about their health effects and public policy implications, which can only be addressed with suitable data. We explore the relationship between self-employment and health by drawing on comprehensive longitudinal administrative data to explore variation in individual work status and by applying novel instrumental variables. We focus on an objective outcome—hospital admissions—that is not subject to recall or other biases that may affect previous studies. Our main findings, based on a sample of about 6,500 individuals followed monthly from 2005 to 2011 and who switch between self-employment and wage work along that period, suggest that self-employment has a positive effect on health as it reduces the likelihood of hospital admission by at least half.

We all know what a pharmacy is: a place where we can obtain chemical products, which we call pharmaceuticals. Not long ago, these products were manufactured at the pharmacy. With the proper scientific advances and the development of modern manufacturing processes, the pharmacy evolved into a place that mostly makes available such chemical products and helps people by counseling them. Pedro Pita Barros enlightened us on this topic.
