Utility Analysis and the Consumption Function: An Interpretation of Cross-Section Data

This article suggests that while mental health problems affect 10—20% of children and adolescents worldwide, the mental health needs of children and adolescents are neglected, especially in low-income and middle-income countries. The authors review the evidence and the gaps in the published work in terms of prevalence, risk and protective factors, and interventions to prevent and treat childhood and adolescent mental health problems.

Terror in the Mind of God: The Global Rise of Religious Violence

1 July 7, 2010, marks the fifth anniversary of the 2005 terrorist attacks on London’s Metro system. In 2005, terrorists launched a coordinated attack against London’s transportation system, with 3 bombs detonating simultaneously at three different Metro stations and a fourth bomb exploding an hour later on a city bus. In all, there were 52 victims in these bombings with an additional 700 injuries resulting. The four terrorists who executed the attacks were killed in the explosions.

We test eight hypotheses on political factors influencing the likelihood that a fiscal policy adjustment occurs. We employ a panel discrete choice model for 20 OECD countries for the period 1970–2003. Two different definitions of fiscal adjustments are used to capture the differences between rapid and gradual adjustments. We find that these types of fiscal adjustment are primarily driven by economic factors and are hardly affected by political variables. The likelihood that a rapid adjustment takes place is only influenced by upcoming elections, while the likelihood that a gradual adjustment takes place increases in case of broad policy reform.

Do political variables affect fiscal policy adjustment decisions? New empirical evidence

We study the effects of an annuity market imperfection on individual agents’ labour supply and retirement decisions and on the macroeconomic growth rate in an overlapping generations model with endogenous growth. We model imperfect annuities by introducing a load factor on the interest rate faced by finitely-lived agents. Our core model features age-independent wages and a constant mortality rate. In the first extension we study the implications for microeconomic decisions and macroeconomic outcomes of a hump-shaped life-cycle profile in labour productivity, whilst in the second extension we postulate a realistic mortality process. Our main findings are that the limited availability of annuities induces agents to retire early in the first two models, but later in the model with age-dependent mortality. In all cases, the general equilibrium repercussion is that economic growth is lower under imperfect annuities than with perfect annuities.

Annuity market imperfection, retirement and economic growth

A growing literature acknowledges the association between childhood socioeconomic status (SES) and health in late adulthood (i.e., 50+). Less, however, is known about the association with mental health outcomes, such as depression. We use the Survey on Health, Ageing and Retirement in Europe (SHARE) to analyse overall and gender-specific associations between childhood SES and late-adulthood depression.Using life-history and contemporaneous data from 21,989 SHARE respondents in combination with principal component analysis we construct indices of childhood SES. We measure late-adulthood depression using the EURO-D scale. Contemporaneous SES is operationalized as the logarithm of household equivalised income. We estimate associations using linear regression models.We document a positive association between childhood SES and the late-adulthood EURO-D score. The association persists even when allowing for contemporaneous SES. Zooming in on gender-specific associations reveals that the association for mental health is particularly pronounced for women.Our findings reveal the long-term association between childhood socioeconomic conditions and depression later in life, which persists even after taking into account current socioeconomic conditions and are stronger for women than for men. These results imply that boosting childhood socioeconomic conditions can potentially have effects lasting well beyond the childhood phase.
