Essays on the economic effects of pension-related policies

This thesis analyses the economic effects of changes in pension-related policies. Chapter 1 provides an overview. Chapter 2 estimates the impact of pension-related policies on household spending. The identification exploits the deviation in pensioner income and expenditure caused by the introduction of a new pension system during the 1980s and the 1990s in Spain and constructs a new narrative series of legislated pension changes. I find that increases in the average pension have a roughly one-for-one effect on pensioner spending. The strongest effects are on the wealthy pensioners, with associated high levels of expenditure, income, and real estate. Estimates for different categories of expenditure indicate that benefit increases trigger the consumption-rich to spend more on durables, while the consumption- and income-poor pensioners spend more on non-durables and necessities such as food. Chapter 3 compares the dynamic aggregate effects of exogenous shocks to two key components of public expenditure in the United States, government income transfers and government spending. In an SVAR framework, I instrument the structural shocks to public expenditure with exogenous measures of changes in federal spending constructing a new narrative variable of legislated increases in US social security benefits. I demonstrate that shocks to different types of public expenditure do not have the same macroeconomic impact. The estimated government spending multiplier is between 0 and 1, while increases in transfers generate a multiplier effect above 1. Chapter 4 focuses on the aggregate effects of changes in old-age pensions and for a sample of European Union countries. This chapter constructs another new measure of transfer shocks building on a dataset by public finance experts of the European System of Central Banks (ESCB). I find that increases in old-age pensions have a positive impact on aggregate expenditure components and employment consistent with a multiplier effect of between 0 and 1

REMANDO A CONTRACORRIENTE

Resumen: Desde Lalonde sabemos que los determinantes que más influyen en la Salud de la población son el estilo de vida, la genética y el entorno. La sanidad representa solo el 10% y es el determinante que más recursos consume. Está demostrado que un enfoque salutogénico centrado en los determinantes sociales de la salud y el apoyo de políticas públicas para mejorar el entorno, son más eficientes a largo plazo que la medicina centrada en los hospitales, la tecnología y la superespecialización. La Atención Primaria (AP) que tiene un enfoque centrado en la persona y las familias con una visión comunitaria, es el nivel idóneo para proveer atención sanitaria, y para influir en los estilos de vida. Sin embargo no se invierte en AP. En este artículo revisamos los condicionantes socioeconómicos y políticos que influyen de manera global en la falta de interés en el desarrollo de la AP. Abstract: At Lalonde we know that the determinants that most influence the health of the population are lifestyle, genetics and the environment. Health represents only 10% and is the determinant that consumes the most resources. It has been shown that a salutogenic approach focused on the social determinants of health and the support of public policies to improve the environment are more efficient in the long term than medicine focused on hospitals, technology and super-specialization. Primary Care (PC) that has an approach centered on the person and families with a community vision, is the ideal level to provide health care, and to influence lifestyles. However it is not invested in PC. In this article we review the socioeconomic and political factors that globally influence the lack of interest in the development of PC

Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins

Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota. Generalized linear models showed that a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability. Increases in TDI were explained through a significant increase in toxin variants such as MC-YR, anatoxin and cylindrospermopsin, accompanied by a decreasing presence of MC-LR. While global warming continues, the direct and indirect effects of increased lake temperatures will drive changes in the distribution of cyanobacterial toxins in Europe, potentially promoting selection of a few highly toxic species or strains

Data Descriptor: A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins

Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ecosystem services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution and climate-change induced stressors, like poor transparency, increased water temperature and enhanced stratification. Consistency in data collection and analysis methods is necessary to achieve fully comparable datasets and for statistical validity, avoiding issues linked to disparate data sources. The European Multi Lake Survey (EMLS) in summer 2015 was an initiative among scientists from 27 countries to collect and analyse lake physical, chemical and biological variables in a fully standardized manner. This database includes in-situ lake variables along with nutrient, pigment and cyanotoxin data of 369 lakes in Europe, which were centrally analysed in dedicated laboratories. Publishing the EMLS methods and dataset might inspire similar initiatives to study across large geographic areas that will contribute to better understanding lake responses in a changing environment
