Biased Risk Perceptions of Longevity and Disability in Old Age

Rational learning theories postulate that information channels and cognitive biases such as individual optimism may influence an individuals assessment of the risk of undesired events, especially with regard to those that have a cumulative nature. This is the case with disability in old age, which may take place upon survival to an advanced age, and such factors have been regarded as responsible for certain individual behaviours (for example, the limited incidence of insurance purchase). This paper examines the determinants of individual perceptions with regard to disability in old age and longevity. The cumulative nature of such perceptions of risk is tested, and potential biases are identified, including optimism and a set of information determinants. Empirical evidence from a representative survey of Catalonia is presented to illustrate these effects. The findings from this research suggest a significant overestimation of disability in old age, yet this is not the case with longevity. Furthermore, individual perceptions with regard to disability in old age, unlike those with regard to longevity, exhibit on aggregate an optimistic bias and, are perceived as cumulative risks. Gender influences the perceived risk of disability in old age at a population level but not at the individual level, and the opposite holds true for age. Finally, self-reported health status is the main variable behind risk perceptions at both the individual and population level.longevity, disability in old age, risk perceptions, optimism, cumulative risks

Unveiling vertical state downscaling: identity and/or the economy?

State rescaling may take a variety of shapes although scant research has been carried out into the mechanisms and economic incentives that underpin rescaling processes. Recent literature in economics, economic sociology and political economy has identified at least two broad rescaling mechanisms, namely the development of regional identity - operating at the cultural level and proxing preference heterogeneity-, and the heterogeneity in levels of economic development, which influence the extent of regional redistribution. This paper empirically examines the mechanisms of vertical state rescaling by drawing upon empirical evidence from Catalonia and the Basque Country, to explore the evolution of sub-state identity and the rise of inter-territorial fiscal grievances - weakening intraregional economic solidarity. Findings corroborate the idea that the combination of widening sub-national identity raises the costs of managing heterogeneous spatial identities and strengthens support for vertical state downscaling. Similarly, ending regional fiscal solidarity it is found to increase the average income of Catalonia by 37% and even 17% in the Basque Country. However, the effect of regional identity exceeds that of regional redistribution in explaining state rescaling support in the magnitude of one to seven. These findings speak to the debate on the formation of Europe, in that they reveal limits to regional redistribution and highlight the importance of a common spatial identity

A better understanding of the behavioural constraints that people face will help policy makers to more effectively target public policy interventions that aim to change their actions

Government interventions often have very different outcomes to those desired by policy makers. Joan Costa Font argues that the development of behavioural economics offers a means to more thoroughly examine the behavioural constraints faced by those who are targeted by specific policies. Behavioural economics is not only better equipped to account for failures but if applied to public policy, it could also give rise to more effective public sector intervention

Obesity and the Incidence of Chronic Diseases: a Seemingly Unrelated Probit Approach

Western societies can reduce avoidable mortality and morbidity by better understanding the relationship between obesity and chronic disease. This paper examines the joint determinants of obesity and of heart disease, diabetes, hypertension, and elevated cholesterol. It analyzes a broadly representative Spanish dataset, the 1999 Survey on Disabilities, Impairments and Health Status, using a health production theoretical framework together with a seemingly unrelated probit model approach that controls for unobserved heterogeneity and endogeneity. Its findings provide suggestive evidence of a positive and significant, although specification-dependent, association between obesity and the prevalence of chronic illness.hypertension, cardiovascular disease, high cholesterol, chronic illness, health production, body mass index, obesity, diabetes

Eastern European Countries and the EMU: departure situation and transition strategies.

The large amount of literatuture wihin the EMU makes compleatly imposible in one paper to analyze the consequences of the creation of a "monetary zone " in Europe. However, the recent decision of the European Council to incorporate in two phases the most of Eastern European Countires, introduces an interessant issue in order to evaluate the effects in terms of stability, future, dimension and optimality of a EMU based on 21 states. The paper starts explaining the baseic advances of the EMU, introducing some general data of the countries that are suposed to enter in future. As a second part of the paper the basic points of the Optimum Currency Areas will be established, and finally the third part would be an analysis of the future structure of the EMU using the OCA theory and and empirical analysis.

Generational Effects on Adult Height in Contemporary Spain: Exploring Gender and Individual Heterogeneity

As adult height is a well-established retrospective measure of health and standard of living, it is important to understand the factors that determine it. Among them, the influence of socio-environmental factors has been subjected to empirical scrutiny. This paper explores the influence of generational (or environmental) effects and individual and gender-specific heterogeneity on adult height. Our data set is from contemporary Spain, a country governed by an authoritarian regime between 1939 and 1977. First, we use normal position and quantile regression analysis to identify the determinants of self-reported adult height and to measure the influence of individual heterogeneity. Second, we use a Blinder-Oaxaca decomposition approach to explain the gender height gap and its distribution, so as to measure the influence on this gap of individual heterogeneity. Our findings suggest a significant increase in adult height in the generations that benefited from the countrys economic liberalization in the 1950s, and especially those brought up after the transition to democracy in the 1970s. In contrast, distributional effects on height suggest that only in recent generations has height increased more among the tallest. Although the mean gender height gap is 11 cm, generational effects and other controls such as individual capabilities explain on average roughly 5% of this difference, a figure that rises to 10% in the lowest 10% quantile.blinder-oaxaca decomposition, quantile regression, generational effects, adult height, gender gap, individual heterogeneity

Socio-Economic Inequalities in Reported Depression in Spain : A Decomposition Approach

Recent evidence questions some conventional view on the existence of income-related inequalities in depression suggesting in turn that other determinants might be in place, such as activity status and educational attainment. Evidence of socio-economic inequalities is especially relevant in countries such as Spain that have a limited coverage of mental health care and are regionally heterogeneous. This paper aims at measuring and explaining the degree of socio-economic inequality in reported depression in Spain. We employ linear probability models to estimate the concentration index and its decomposition drawing from 2003 edition of the Spanish National Health Survey, the most recent representative health survey in Spain. Our findings point towards the existence of avoidable inequalities in the prevalence of reported depression. However, besides pure income effects explaining 37% of inequality, economic activity status (28%), education (15%) and demographics (15%) play also a key encompassing role. Although high income implies higher resources to invest and cure (mental) illness, environmental factors influencing in peoples perceived social status act as indirect path as explaining the prevalence of depression. Finally, we find evidence of a gender effect, gender social-economic inequality in income is mainly avoidable.occupational status, education, socio-economic inequities in health, depression

The hedonic placebo effect of traditional medicines

To date, the scientific evidence on traditional medicines is scant and under-developed, yet, paradoxically individuals continue to use it and claim high satisfaction levels. What can explain this effect? Using self-collected data from Ghana we argue that variations in satisfaction across individuals can be attributed to the hedonic placebo effect gained from using traditional medicines, in which processes involved with its consumption are as important, if not more important, than measures of self-reported health outcome. Findings suggest that individuals’ health seeking behaviour should be evaluated using procedural, as well as outcome, utility

Does culture matter at all in explaining why people still use traditional medicines?

Why do individuals still use traditional medicines when modern treatments are available? Economic explanations for an individual’s use of traditional instead of modern medicines are scarce and often fail to consider explanations beyond the conventional. This paper puts forward an economic explanation for the use of traditional medicine. First, traditional medicines were the default form of health care available in pre-colonial times where industry influence was yet to develop. Hence, both those individuals who exhibit lower incomes and are left out of health insurance coverage are more likely to use traditional medicines. Second, cultural attitudes and ethnic group controls explain variation in utilisation, even among those who have health insurance. Results are suggestive of the validity of cultural interpretations
