Economics has been described as " the branch of social science that deals with the production and distribution and consumption of goods and services and their management" ( http://www.cogsci.princeton.edu/~wn/ ). In this case the "goods and services" are those of healthcare.
Sites listed here will focus on topics such as health system cost-effectiveness, value in medicine, political aspects of finance and the analysis of healthcare data.
If your site concerns primarily the academic, informational or research aspects of economics, please submit it here instead.
