Sunlight is the most important energy source of Earth. All earthlings live thanks to the ability of plants and bacteria to transform solar energy into chemical one. As sunlight is a free, and practically unlimited, energy source it is easy to understand the general interest in finding efficient ways of transforming it into electrical power […]
In the first part of this series, I presented the rationale for government intervention in the health sector and, then, summarized the findings of Stabile and Thomson (2014) on the problems of financing and risk pooling in different health systems. In this second part I continue with the problems on demand, coverage decisions, evaluation and […]
