Why do the majority of African countries fail to take the steps that would lead them towards greater development? The aim of this work is to determine the factors affecting development, not only the economic ones, which play a central role in economic literature, but also social. To do so, we have used a wide sample of countries and have estimated a panel data for 171 countries of those that have been members of the United Nations (UN) for a period of 16 years (from 1995 to 2010 inclusive). Our results lead us to conclude that monetary instability and the colonial past of these countries have had a negative impact on their level of human development. However, improvements in the efficiency of governmental policy and instruments, investment in greater democracy, greater stability and less corruption, have, in all cases, a positive effect on human development in these countries.

The age per se is not directly related to consumption of hospital resources. Therefore, aging does not necessarily imply higher consumption or increased hospital costs. Emergency admitted in-patients are older and more severe and complex than the scheduled ones, thus consuming more resources and implying higher hospital costs; the same is true for the deceased versus the survivors.

This essay has a double aim. On the one hand, to identify what are the determinants in the inequality in health. On the other hand, to estimate to what extent the inequality indicator used is important. To do this, we use a cross-sectional model for 176 countries. The achieved results allow concluding that the choice of the inequality measurement is a key element in this type of studies. Also, inequality in income distribution, the weight of the rural population and capitalism make inequality in health increase.

The objective of this work is to analyse the factors that influence a greater or lesser inequality in income distribution in the 27 EU countries, paying particular attention to the effect that the economic crisis has had. For this purpose we have used panel data covering a period of 16 years (from 1996 to 2011, inclusive), and we have introduced additional variables over and above those normally used, such as the ideology of the governing party, the economic freedom index, as well as the ‘crisis’ variable. The results obtained enable us to conclude that while the economic crisis has not necessarily caused a worsening in inequality, the response of European governments by means of social policy has not so far proved effective in the fight against the lack of equality in income distribution.
