In the past few years there has been a growing recognition of the effect of peers on an individual’s behaviour. Recent sociological literature has shown, for instance, that friends influence each other in areas such as smoking, drinking, and how much we exercise. In our recently published paper, we examine the influence of friends on an individual’s decision to have a child. So far, research on fertility behavior has largely neglected the fact that people are embedded in social networks, thereby failing to acknowledge that couples do not make fertility choices in a vacuum.
Historical evidence strongly supports that economic growth and prosperity have been associated to declining mortality rates. To reinforce this principle, infant mortality and life expectancy are widely used as living standard indicators in cross-regional comparisons. While positive economic and social developments are concretized as gains in life expectancy, the recessionary implications on mortality rates are not that straightforward. Whether severe economic downturns affect the aggregate death rates has been the focus of much research, and findings are mixed. They appear to be sensitive to the choice of country, to the time period examined, and the length and intensity of the economic downturns.
