How difficult would it be for individuals to adjust to zero economic growth?

 


It would not be difficult for governments to achieve zero economic growth. They would just need to do more of the things that they are doing at present to slow down the adoption of new technology, create policy uncertainty, protect inefficient firms and industries from competition, and reduce the incentives for people to work. I could make a more detailed list of policies they could adopt, but I am not in the business of advising politicians about how to achieve zero growth.

Those who argue for lower economic growth don’t talk much about adverse psychological impacts that people might experience as a consequence. They seem to assume that if economic growth was stopped, average life satisfaction would stay where it is now. The basis for that assumption is that in high-income countries, further increases in income offer negligible benefits in terms of increased life satisfaction. That is consistent with the views of Richard Easterlin, who was made famous by his pathbreaking research on the relationship between economic growth and indicators of subjective well-being. Easterlin argues:

“At a point in time, happiness varies directly with income both among and within nations, but over time the long term growth rates of happiness and income are not significantly related.”

That passage is quoted in an article by Michael Plant which provides quite a strong defense of Easterlin’s position.

In my view, Easterlin is broadly correct. As incomes rise, additional economic growth can be expected to make a progressively smaller contribution to psychological well-being (as commonly measured by average life satisfaction ratings). Nevertheless, people may have good reasons to seek to have higher incomes. As I discussed in Chapter 1 of Freedom, Progress, and Human Flourishing, psychological well-being is only one of the goods of a flourishing human.

However, the main point I propose to make in this essay is that adoption of policies to achieve zero economic growth would be likely to pose substantial psychic costs (psychological adjustment costs) for many people as they are forced to revise their expectations downwards. I begin the essay by discussing international data on the perceptions that people have about their standard of living relative to their parents and then link that data to average life satisfaction.

1.        Are perceptions of standard of living relative to parents related to economic growth?

In the latest round of the World Values Survey (WVS 2017-22) respondents were asked the following question about their standard of living: “Comparing your standard of living with your parents’ standard of living when they were about your age, would you say that you are better off, worse off or about the same?” (I downloaded that data for as many countries as possible using the WVS’s excellent facility for online analysis.)

Matching the WVS data with World Bank data on per capita income (NY.GDP.PCAP.PP.KD) and rate of growth in per capita income (NY.GDP.PCAP.KD.ZG) left me with a data set covering 63 countries. I used income data for 2002, and growth data for the period from 2002 to 2022. The reasoning behind that was to separate the growth experience prior to 2002 (reflected in income levels for 2002) from subsequent growth experience.

(It would have been nice to be able to conduct this analysis using a larger data set, but beggars can’t be choosers. I hope that one day someone will attempt to replicate and extend the study using a data set for a larger number of countries.)

Countries were allocated to four groups of approximately equal size:

  • Low-income, low growth e.g. Pakistan, Kenya
  • Low-income, high growth e.g. China, Indonesia, India
  • High-income, low growth e.g. U.S.A., Germany, Australia
  • High-income, high growth e.g. South Korea, Singapore.




The average percentage of those who consider themselves to be better off than their parents at a comparable age is shown in Figure 1a. As might be expected, a higher percentage of people are in the “better off” category in the high-income and high growth countries.



Figure 1b shows that the percentages in the “worse off” category are lowest in the high income and high growth countries.


Figure 1c shows that the percentage who are “about the same” is higher in the low growth countries than in the high growth countries.




Overall, this analysis suggests that perceptions of standard of living relative to parents are positively related to past economic growth experience of the countries in which people live. Historical growth experience, reflected in per capita income levels in 2002, and more recent growth experience over the last 20 years are both relevant.

2.        Do perceptions of standard of living relative to parents differ according to the age of respondents?


As might be expected, Figure 2a shows that in the high income, low growth countries older people are less adversely affected by low growth than are young people. The fact that more than half of respondents aged 50+ still perceive their standard of living to be better than that of their parents, presumably reflects the benefits of higher economic growth rates earlier in their working lives.


The picture presented in Figure 2b is consistent with that in Figure 2a.


Figure 2c indicates that there is not much difference between age groups among respondents who perceive that their standard of living is about the same as that of their parents.




Overall, perceptions of standard of living relative to parents do differ somewhat according to the age of respondents. In particular, in the high-income countries, low growth has a greater adverse impact on young people than on old people.

3.        Are life satisfaction ratings influenced by perceptions of standard of living relative to parents?

Figure 3 shows average life satisfaction ratings for each of the four categories of countries and each of the three categories of responses to the question about standard of living relative to parents.

Several observations may be made:

First, average life satisfaction ratings are higher for the high-income, low growth group than for other countries. It is somewhat surprising that life satisfaction is not as high, or higher in the high-income, high growth group. It might be interesting to speculate about that result, but my focus is on the question of whether perceptions of standard of living relative to parents influence life satisfaction ratings.

Second, average life satisfaction ratings of those who perceive their standard of living to be about the same as their parents are not much lower than for those who perceive their standard of living to be higher than that of their parents.

Third, average life satisfaction ratings of those who perceive their standard of living to be lower than that of their parents are substantially lower than for those who perceive their standard of living to be higher than that of their parents. That is true for all four groups of countries.

The important point to note is that the perception of having a lower standard of living than parents had at a comparable age has a substantial adverse impact on life satisfaction ratings.

Implications

The implications of the observed relationship between perceptions of standard of living relative to parents at a comparable age and economic growth experience are obvious. Lower economic growth is likely to result in increasing percentages of people having lower living standards than their parents. If economic growth is brought to a halt, the percentages who perceive that their living standards are lower than those of their parents would presumably end up approximately equal to the percentages who perceive that their incomes are higher than those of their parents.  

The implications for average life satisfaction of an increase in percentages who feel worse off than their parents at a comparable age are also obvious from the analysis presented above. An increase in the percentage of people who perceive that they have a lower standard of living than their parents is likely to result in a decline in average life satisfaction. The extent and duration of the associated decline in psychological well-being could be expected to vary depending on the resilience of individuals.

The analysis suggests that the psychic costs of adjustment to zero economic growth would initially fall most heavily on young people. In countries where per capita incomes are relatively high, older members of the population have been able to retain the benefits of higher economic growth that occurred earlier in their working lives.

In an earlier study focusing on Australia I found that in the 18-54 years group 33% felt better off than their parents; 48% felt worse off, and 19% felt that their incomes were about the same as their parents’ incomes at a comparable age. Consistent with the findings of the current study, those who felt worse off than their parents had substantially lower life satisfaction.

The Australian study looked more deeply at the group who feel worse-off than their parents, to observe the extent to which their life satisfaction experiences interacted with their resilience. As might be expected, the results indicated that people with relatively high resilience were able to maintain relatively high life satisfaction despite feeling worse off than their parents were at a comparable age.

Implications of three different kinds follow from acknowledging that lower economic growth causes an increasing proportion of the population to experience the psychic costs associated with disappointed expectations.

First, at an individual level, those affected are posed with the problem of how to adjust to the new set of circumstances. They may need the support of family and friends, and possibly professional help, to moderate the psychic costs involved.

Second, governments, and those advising them, need to consider whether there are more sensible ways to pursue policy objectives. The psychic costs associated with zero economic growth make this outcome less desirable, irrespective of whether it is pursued deliberately or occurs as a consequence of the incompetence of those responsible for economic policies.

Third, observers of interactions within social and economic systems need to consider likely responses of voters who are disappointed that it has become more difficult to achieve the goal of being able to maintain a standard of living at least as high as that of their parents. Voters can be expected to blame government policies for their predicament. From a social science perspective, the interesting question is whether government policy responses are more likely to restore economic growth or make the problem worse.

Conclusions

This essay has focused on the likely impact on average life satisfaction at a national level of policies to achieve zero economic growth. Data from the World Values Survey has been used to examine the relationship between the perceptions of respondents about their standard of living relative to their parents at a comparable age and economic growth in the countries in which they reside. That data has then been linked to average life satisfaction.

The main findings are:

Perceptions of standard of living relative to parents are positively related to past economic growth experience of the countries in which people live.

In the high-income countries, low growth has a greater adverse impact on young peoples’ perceptions of their standard of living relative to parents than on the corresponding perceptions of old people.

The perception of having a lower standard of living than parents at a comparable age has a substantial adverse impact on life satisfaction ratings.

These findings imply that lower economic growth rates would be likely to result in an increasing proportion of the population having lower living standards than their parents, and hence, lower average life satisfaction. The psychic costs of adjustment to zero economic growth would initially fall most heavily on young people.

Zero economic growth would have implications for individuals, governments and social scientists:

  • At an individual level, those whose expectations have been disappointed are posed with the problem of how to adjust.
  • Governments and their advisors are posed with the problem of considering whether there are more sensible ways of pursuing policy objectives.
  • Social scientists are posed with the problem of assessing whether voters in different countries are more likely to respond in ways that will fix the problem by restoring economic growth, or to make it worse by favoring policies that will lead to economic decline.
The problems of psychological adjustment to lower economic growth should no longer be ignored.

Addendum
I have received the following comment by email from Arthur Grimes, Senior Fellow, Motu, Wellington, New Zealand:

"This is an excellent article - thanks for the contribution to understanding these issues.

Another angle is to think about how people's life satisfaction reacts when incomes in their country grow more slowly than comparable and/or neighboring countries. There are a couple of studies that show an analogous situation to your results; i.e. people in more slowly growing countries feel worse off (in subjective wellbeing terms) than do people in higher growth countries."
