Intergenerational equity in economic, psychological, and sociological contexts, is the concept or idea of fairness or justice between generations. The concept can be applied to fairness in dynamics between children, youth, adults and seniors, in terms of treatment and interactions. It can also be applied to fairness between generations currently living and generations yet to be born.
Conversations about intergenerational equity occur across several fields. 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, global warming 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, with the focus falling 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 and social justice.
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.
While slavery is illegal in all countries today, North Korea has a policy called, "Three Generations of Punishment" which has been documented by Shin Dong-hyuk and used as a moral paragon of punishing children for parents' mistakes. Stanley Druckenmiller and Geoffrey Canada have applied this concept (calling it "Generational Theft") to the large increase in government debt being left by the Baby Boomers to their children.
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." in terms of an economical context. Intergenerational equity refers to relationship that a particular family has on resources. An example is the forest-dwelling civilians in Papua New Guinea, who for generations have lived in a certain part of the forest which thus becomes their land. The adult population sell the trees for palm oil to make money. If they cannot make a sustainable development on managing their resources, their next or future generations will lose this resource.
One debate about the national debt relates to intergenerational equity. For example, if one generation is receiving the benefit of government programs or employment enabled by deficit spending and debt accumulation, to what extent does the resulting higher debt impose risks and costs on future generations? There are several factors to consider:
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." Young workers face high unemployment and studies have shown their income may lag throughout their careers as a result. Teacher jobs have been cut, which could affect the quality of education and competitiveness of younger Americans.
Australian politician Christine Milne made similar statements in the lead up to the 2014 Carbon Price Repeal Bill, naming the Liberal National Party (elected to parliament in 2013) and inherently its ministers, as intergenerational thieves; her statement was based on the party's attempts to roll back progressive carbon tax policy and the impact this would have on the intergenerational equity of future generations.
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. Further, he admits that the long-term insolvency of Social Security will likely lead to be further unintentional intergenerational transfers. However, Broad 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.
Intergenerational equity is often referred to in environmental contexts, as younger age cohorts will disproportionately experience the negative consequences of environmental damage. Two perspectives can be taken on what should be done to ameliorate environmental intergenerational equity: the "weak sustainability" perspective and the "strong sustainability" perspective. From the "weak" perspective, intergenerational equity would be achieved if losses to the environment that future generations face were offset by gains in economic progress. From the "strong" perspective, no amount of economic progress can justify leaving future generations with a degraded environment. According to Professor Sharon Beder, the "weak" perspective is undermined by a lack of knowledge of the future, as we do not know which intrinsically valuable resources will not be able to be replaced by technology. We also do not know to what extent environmental damage is irreversible. Further, more harm cannot be avoided to many species of plants and animals. Other scholars contest Beder's point of view. Professor Wilfred Beckerman insists that "strong sustainability" is "morally repugnant", particularly when it overrides other moral concerns about those alive today. Beckerman insists that the optimal choice for society is to prioritize the welfare of current generations above future generations. He suggests placing a discount rate on outcomes for future generations when accounting for generational equity. Beckerman is extensively criticized by Brian Barry and Nicholas Vrousalis.
In September 2015, a group of youth environmental activists filed to sue the U.S. federal government for insufficiently protecting against climate change. Their statement emphasized the disproportionate cost of climate-related damage younger generations would bear. It stated “Youth Plaintiffs represent the youngest living generation, beneficiaries of the public trust. Youth Plaintiffs have a substantial, direct, and immediate interest in protecting the atmosphere, other vital natural resources, their quality of life, their property interests, and their liberties. They also have an interest in ensuring that the climate system remains stable enough to secure their constitutional rights to life, liberty, and property, rights that depend on a livable Future.” In November 2016, the case was allowed to go to trial after US District Court Judge Ann Aiken denied the federal government’s motion to dismiss the case. In her opinion and order, she said, “Exercising my ‘reasoned judgment,’ I have no doubt that the right to a climate system capable of sustaining human life is fundamental to a free and ordered society." As of April 2017, the trial was put on hold with a stay. The Ninth Circuit heard oral arguments on the stay in November of 2017 and a ruling is expected in February of 2018.
Discussions of intergenerational equity in standards of living have referenced differences between people of different ages as well as differences between people of different generations. Two perspectives on intergenerational equity in living standards have been distinguished by Rice, Temple and McDonald. The first perspective – a "cross-sectional" perspective – focuses on living standards at a particular point in time and how these living standards vary between people of different ages. The relevant issue is the degree to which, at a particular point in time, people of different ages enjoy equal living standards. The second perspective – a "cohort" perspective – focuses on living standards over a lifetime and how these living standards vary between people of different generations. For intergenerational equity, the relevant issue becomes the degree to which people of different generations enjoy equal living standards over their lifetimes. Three indicators of intergenerational equity in economic flows, such as income, have been proposed by D'Albis, Badji, El Mekkaoui and Navaux. Their first indicator originates from a cross-sectional perspective and describes the relative situation of an age group (retirees) with respect to the situation of another age group (younger people). Their second indicator originates from a cohort perspective and compares the standards of living of successive generations at the same age. D'Albis, Badji, El Mekkaoui and Navaux's third indicator is a combination of the two previous criteria and is both an inter-age indicator and an intergenerational indicator.
In Australia, notable equality has been achieved in living standards, as measured by consumption, among people between the ages of 20 and 75 years. Substantial inequalities exist, however, between different generations, with older generations experiencing lower living standards in real terms at particular ages than younger generations. One way to illustrate these inequalities is to look at how long different generations took to achieve a level of consumption of $30,000 per year (2009-10 Australian dollars). At one extreme, people born in 1935 achieved this level of consumption when they were roughly 50 years of age, on average. At the other extreme, Millennials born in 1995 had achieved this level of consumption by the time they were around 10 years of age.
Considerations such as this have led some scholars to argue that standards of living have tended to increase generation over generation in most countries, as development and technology have progressed. When taking this into account, younger generations may have inherent privileges over older generations, which may offset the redistribution of wealth towards older generations.
Some scholars consider the changing cultural trends that move society away from the norm of adult children caring for elderly parents to be an intergenerational equity issue. The older generation had to care for their parents, as well as their own children, while the younger generation must only care for their children. This is especially true in countries with weak social security systems. Professor Sang-Hyop Lee describes the presence of this phenomenon in South Korea, explaining that the current elderly now have the highest poverty rate among any developed country. He notes that it is particularly frustrating because the elderly usually invest a lot in their children's education, and they now feel betrayed.
Other scholars express different opinions on which generation is truly disadvantaged by elderly care. Professor Steven Wisensale describes the burden on current working age adults in developed economies, who must care for more elderly parents and relatives for a longer period of time. This problem is exacerbated by the increasing involvement of women in the workforce, and by the dropping fertility rate, leaving the burden for caring for parents, as well as aunts, uncles, and grandparents, on fewer children.
Conversations about intergenerational equity are also relevant to social justice arenas as well, where issues such as health care are equal in importance to youth rights and youth voice are pressing and urgent. There is a strong interest within the legal community towards the application of intergenerational equity in law.
