Old-age-security hypothesis

Old-age-security hypothesis is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Old-age-security hypothesis rather than just read about it. In short: The old-age-security hypothesis is an economic hypothesis according to which parents view their children as a source of income and personal services in old age. Within the framework of this hypothesis, the demand for children is considered as the need to ensure a safe old age.

Key takeaways

  • Old-age-security hypothesis belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Old-age-security hypothesis to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Old-age-security hypothesis from memory before moving on to harder problems.

Reference excerpt

The old-age-security hypothesis is an economic hypothesis according to which parents view their children as a source of income and personal services in old age. Within the framework of this hypothesis, the demand for children is considered as the need to ensure a safe old age. As a consequence, increasing the profitability of alternative assets or introducing a universal public pension system reduces the demand for children.

Description According to this hypothesis, the presence of a state pension system reduces the overall birth rate and hinders investment in the human capital of children, which in the long term leads to a decrease in the size of the working-age population and affects their overall income growth. On the contrary, the absence of alternative assets or state pension provision makes it necessary to have children. This hypothesis is based on two basic assumptions: people control the number of children born and people in their actions are guided by selfish motives (that is, proceeding only from their own consumption throughout life). According to this hypothesis, payments from children to support their elderly parents are seen as a return on loans that parents spent to provide for their children in childhood. Alternative hypotheses explaining the birth rate are intergenerational altruism and various hypotheses related to the labor market. The earliest mention of the inverse relationship between the birth rate and the level of the population's pension is found in Leibenstein in 1957. Van Groezen, Leers and Meijdam in 2003, Sinn in 2007, Cigno and Werding in 2007, Ehrlich and Kim in 2007, Van Groezen and Meijdam in 2008, Gahvari in 2009, Cigno in 2010, expressed the opinion about the decline in the birth rate as a consequence of the introduction of the pension system. Fenge and von Weizsäcker in 2010, Regös in 2014, Boldrin, De Nardi and Jones in 2015. Guinnane in 2011, based on empirical evidence of declining fertility in historical time, considered the introduction of social protection as one of the reasons for the first demographic transition. Cigno and Rosati in 1992, Cigno in 2003, Billari and Galasso in 2009 examined this hypothesis at the level of specific countries and individual pension systems. Cigno and Werding in 2007 gave an overview of work on the relationship between pensions and fertility in the modern period. According to these studies, a smaller pension coverage leads to a higher birth rate.

Alessandro Cigno According to Alessandro Cigno, ensuring old age is an incentive for raising children and a dominant factor in increasing the birth rate. Cigno also believes that it has been proven that the coverage of the population by the pension system reduces the birth rate, although it increases household savings. In his opinion, the state pension system prevents parents from investing in the human capital of their children. Considering the rapidly aging population and the imbalance between the number of recipients of pensions and those who pay pension contributions as the reason for the deficit of the pension fund and the decrease in the income of pensioners, Alessandro Cigno proposes to pay the pension to parents directly from the pension contributions of their children.

Robert Fenge and Beatrice Scheubel In 2017, Robert Fenge and Beatrice Scheubel published an article Pensions and fertility: back to the roots, where they studied the relationship between the development of the state pension system, or rather the dynamics of the share of people participating in pension insurance programs and the dynamics of fertility, using the example of the German Empire at the end of 19 and beginning 20th century. In addition to pensions, the multivariate analysis took into account those factors that scientists usually cite as the cause of the first demographic transition. Together with pensions, the impact of factors such as literacy and urbanization was analyzed. According to Robert Fenge and Beatrice Scheubel, the introduction of pensions in Germany at the turn of the 19th and 20th centuries explains up to 15% of the decline in the birth rate in 1895–1907.

UN Conference on the World Population in Bucharest, 1974

A meeting dedicated to the reduction of the world population was held in Bucharest from August 19 to 30. Participants: more than 1.4 thousand delegates from 136 countries (at that time there were 138 countries in the UN, family planning is already being promoted in 59 countries). Initiator: The USA and the UN. The plan was written in advance, it was mainly developed by the American side, initially contained quantitative target indicators for the CPR (Controlled Population Reduction) for individual countries, but as a result of the protests they had to be removed. It was the first official international document in the field of demography and fertility reduction. The Conference is proud for the first time in history, setting the goal of "curbing population growth" for the peoples. And also worked out specific ways to achieve this Goal. Among them is the introduction of benefits and pensions. "Recognizing the diversity of social, cultural, political and economic conditions, everyone agrees that the following development goals will lead to a moderate birth rate: reduction of infant and child mortality, full involvement of women in the development process (education, economics, politics), promotion of social justice, accessibility of education, eradication of child labor and abuse with children, the introduction of social security and old-age pensions, the establishment of a minimum age for marriage." By this time, demographic policy and "family planning" programs had been successfully applied in Asian countries, in particular in India, Japan, Pakistan and Sri Lanka. In 1974, teaching staff worked in 39 countries, in which about 80% of the population of the "developing world" lived.

Worked examples

Example 1 — a first encounter with Old-age-security hypothesis

Start with the simplest possible case. Write down what Old-age-security hypothesis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Old-age-security hypothesis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Old-age-security hypothesis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Old-age-security hypothesis

In research
Old-age-security hypothesis appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Old-age-security hypothesis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Old-age-security hypothesis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Demographic economics, Human geography, Sociocultural evolution theory, so understanding it makes those chapters shorter.
In everyday life
Look for Old-age-security hypothesis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
