Intergenerational equity

Intergenerational equity 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 Intergenerational equity rather than just read about it. In short: Intergenerational equity in economic, psychological, and sociological contexts, is the notion of fairness or justice between generations. The concept can be applied to fairness in dynamics between children, youth, adults, and seniors.

Key takeaways

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

Reference excerpt

Intergenerational equity in economic, psychological, and sociological contexts, is the notion of fairness or justice between generations. The concept can be applied to fairness in dynamics between children, youth, adults, and seniors. It can also be applied to fairness between generations currently living and future generations. Conversations about intergenerational equity may include basic human needs, economic needs, environmental needs and subjective human well-being. It is often discussed in public economics, especially with regard to transition economics, social policy, and government budget-making. Many cite the growing U.S. national debt as an example of intergenerational inequity, as future generations will shoulder the consequences. Intergenerational equity is also explored in environmental concerns, including sustainable development, and climate change. The continued depletion of natural resources that has occurred in the past century will likely be a significant burden for future generations. Intergenerational equity is also discussed with regard to standards of living, specifically on inequities in the living standards experienced by people of different ages and generations. Intergenerational equity issues also arise in the arenas of elderly care, social justice, and housing affordability.

Political rights

The debate around youth rights, children's rights and the rights of future generations includes discussions around when people should have political power, and how much they should have. Adam Benforado argues, for example, that giving children more political rights than adults results in everyone being better off by, for example, increasing the salience of long-term issues. Those seeking rights or greater consideration for future generations discuss methods such as deliberative democracy, an ombudsman for future generations, or other institutions tasked specifically with considering future generations. Some advocates also want a child impact assessment of policies or decisions to evaluate outcomes for a specific child or even the next generation more broadly.

Public economics usage

History Since the first recorded debt issuance in Sumaria in 1796 BC, one of the penalties for failure to repay a loan has been debt bondage. In some instances, this repayment of financial debt with labor included the debtor's children, essentially condemning the debtor family to perpetual slavery. About one millennium after written debt contracts were created, the concept of debt forgiveness appears in the Old Testament, called Jubilee (Leviticus 25), and in Greek law when Solon introduces Seisachtheia. Both of these historical examples of debt forgiveness involved freeing children from slavery caused by their parents' debt. The leaders of the Haudenosaunee Confederacy considered the precept of seven generation sustainability when making present decisions that could have significant impact on their potential future descendants.

Pope Francis, in his 2015 encyclical letter Laudato si', commented thatWe can no longer speak of sustainable development apart from intergenerational solidarity. Once we start to think about the kind of world we are leaving to future generations, we look at things differently; we realize that the world is a gift which we have freely received and must share with others ... Intergenerational solidarity is not optional, but rather a basic question of justice.

Government debt

Higher government debt levels create significant costs for future taxpayers (e.g., higher taxes, lower government benefits, higher inflation, or increased risk of fiscal crisis). Stanley Druckenmiller and Geoffrey Canada call the large increase in government debt being left by the Baby Boomers to their children "Generational Theft". Future generations could benefit if the investments made with the debt are more valuable than the amount of debt they created. For example, to the extent that borrowed funds are invested today to improve the long-term productivity of the economy and its workers, such as via useful infrastructure projects, future generations may benefit. Economist Paul Krugman wrote in March 2013 that by neglecting public investment and failing to create jobs, we are doing far more harm to future generations than merely passing along debt: "Fiscal policy is, indeed, a moral issue, and we should be ashamed of what we're doing to the next generation's economic prospects. But our sin involves investing too little, not borrowing too much."

Pensions

Underfunded pensions can shift costs to younger generations, which can be motivated by intergenerational selfishness. The U.S. Social Security system has provided a greater net benefit to those who reached retirement closest to the first implementation of the system. The system is unfunded, meaning the elderly who retired right after the implementation of the system did not pay any taxes into the social security system, but reaped the benefits. Professor Michael Doran estimates that cohorts born previous to 1938 will receive more in benefits than they pay in taxes, while the reverse is true to cohorts born after. Also, that the long-term insolvency of Social Security will likely lead to further intergenerational transfers. However, Doran concedes that other benefits have been introduced into U.S. society via the welfare system, like Medicare and government-financed medical research, that benefit current and future elderly cohorts.

Investment management In the context of institutional investment management, intergenerational equity is the principle that an endowed institution's spending rate must not exceed its after-inflation rate of compound return, so that investment gains are spent equally on current and future constituents of the endowed assets. This concept was originally set out in 1974 by economist James Tobin, who wrote that "The trustees of endowed institutions are the guardians of the future against the claims of the present. Their task in managing the endowment is to preserve equity among generations."

Worked examples

Example 1 — a first encounter with Intergenerational equity

Start with the simplest possible case. Write down what Intergenerational equity 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 Intergenerational equity 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 Intergenerational equity 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 Intergenerational equity

In research
Intergenerational equity 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 Intergenerational equity 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
Intergenerational equity is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ageing, Ageism, Cultural generations, so understanding it makes those chapters shorter.
In everyday life
Look for Intergenerational equity 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.
