Disparities in premature mortality: Evidence for the OECD countries.

This paper studies the existence of international health outcome disparities. We focus on the use of the potential years of life lost for a database that includes information from 33 OECD countries and covers the period 1990-2017. The methodology proposed by Phillips and Sul (2007) allows us to reject the existence of a single pattern of behaviour between countries for both males and females, suggesting the existence of severe health outcome inequalities. This methodology estimates the existence of four convergence clubs whose composition slightly varies when comparing the male and female cases. Some socioeconomic factors are found to be very important in explaining the forces that may drive the creation of these convergence clubs. In particular, the evolution of the economy and health policies are pivotal to understanding the creation of these estimated convergence clubs. Additionally, our results offer evidence in favor of the importance of environmental policies to explain these health outcome differences.

Waste generation and the economic cycle in European countries. Has the Great Recession decoupled waste and economic development?

This paper studies the relationship between waste generation and economic development for a sample of European countries. In contrast to previous studies that have considered this relation to be stable over time, we apply methods for testing the presence of structural breaks located at unknown periods. This methodology provides robust evidence against the stability of the relationship, finding ruptures in the so-called dot.com crisis, in the early 2000s, and in episodes related to the Great Recession. Once these breaks are considered, we observe that waste generation shows considerable dependence on the evolution of the economy for those countries with the lowest per capita income levels. This suggests the existence of a trade-off between convergence policies and those aimed at avoiding environmental degradation, suggesting the need to maintain and reinforce environmental policies in the EU.

Waste generation in Spain. Do Spanish regions exhibit a similar behavior?

We analyze waste generation differences across Spanish regions by studying the evolution of two complementary indicators: municipal solid waste per unit of GDP as well as in per capita terms. To that end, we apply the recent statistic developed by Phillips and Sul (2007) which allows us to test for the null hypothesis of convergence. In the present case, this hypothesis is equivalent to admitting that the waste generation follows a similar path across the Spanish regions. Our results lead us to reject this hypothesis, which implies that Spanish regional waste generation is quite heterogenous and exhibits several patterns of behavior. We observe that the northern regions exhibit the lowest waste ratios while the insular and Mediterranean coast regions have the highest waste generation. This different behavior is also explained by some socioeconomic factors. Per capita income, environmental spending and education level are helpful in this regard. The population dispersion and the number of years that a region has been governed by a left-wing party are also associated with lower levels of waste generation. Finally, we can also observe that the regions with the highest levels of waste generation are greatly dependent on the tourism industry. Then, strategies targeting the transit towards a more sustainable economy in Spain should take into account this fact. In particular, the adoption of methods for the reduction of the waste levels generated by tourism activities in these areas can be very useful.

Global Trends in Child Obesity: Are Figures Converging?

Childhood obesity has become one of the most serious global health challenges of our time. The combined prevalence of overweight and obesity has rapidly increased worldwide during the last two decades, especially in some developing countries where obesity is reaching levels on a par with some industrialized countries, or even higher. This fast growth has occurred especially in countries in the midst of rapid social-economic transitions. Most international comparisons focus on the adult population while analyses focusing on the child population are more limited. Using the methodology developed by Phillips and Sul, this paper studies the worldwide evolution of children's body mass index (BMI), overweight and obesity prevalence for a large sample of countries during the period 1975-2016. Our results indicate that the figures for BMI or the prevalence of obesity in different countries do not converge, while the opposite is the case for overweight prevalence in children. Furthermore, there is a non-linear relationship between obesity and income or human capital, indicating that low and middle-income countries require a strong initiative for health policies targeting obesity prevention.
