Will the population bomb prevent the great stagnation?

If only Paul Ehrlich had been right! Population explosion would have meant an explosion in people who could invent new technologies and populate in much larger markets to provide an incentive to invent new products.
Among Paul Ehrlich’s many analytical errors, he did not take into account that more people meant more inventors and more untapped markets.
Jones argued that in the very long run the only way to have further innovation is to have more people. If there are more people undertaking R&D and more people to populate the markets for those inventions, there will be further growth because the decreasing returns to knowledge creation will be overcome by having more R&D workers.
Jones attributes much of the growth in the 20th century to one-off effects that cannot be repeated such as putting more people into higher education:
… growth in educational attainment, developed-economy R&D intensity, and population are all likely to be slower in the future than in the past. These factors point to slower growth in US living standards.
Second, a counterbalancing factor is the rise of China, India, and other emerging economies, which likely implies rapid growth in world researchers for at least the next several decades.
Third, and more speculatively, the shape of the idea production function introduces a fundamental uncertainty into the future of growth. For example, the possibility that artificial intelligence will allow machines to replace workers to some extent could lead to higher growth in the future.
A larger population increases the rate of technological progress by increasing the number of geniuses and other creative people.The doomsday prophecies about the population bomb never took that into account. That is why they are wrong.

Gareth Morgan revealed today a hitherto unnoticed design feature in his Universal Basic Income of $11,000 per annum. It will be phased in over a long time. That will mean that Generation Rent will continue to pay taxes to fund a universal old age pension for their parents and grandparents, but will not be fortunate enough to receive that themselves.

They are not left of their own devices. Generation Rent is expected to save the Universal Basic Income they receive over their working lives to avoid living in poverty in their retirement. Does not strike me as a political winner.
The Morgan Foundation does not understand the implications of time inconsistency for retirement savings policy:
- Which is better? Save for your retirement through the share market or save to own your own home and then present yourself at the local social security office to collect your taxpayer funded old-age pension?
- Under this fine game of bluff, you bleed the taxpayer in your old age and pass on your debt-free home to your children.
This strategy of not saving much for retirement is rational for the less well-paid. The family home is exempt from income and asset testing for social security. If you lose you bet, sell your house and live off the capital. For ordinary workers, this is a good bet. The middle class might prefer to live in a more luxurious retirement.
For ordinary workers, whose wages are not a lot more than their old age pension from the government, a government funded pension is a good political gamble. The old-age pension for a couple in New Zealand is set at no less that 60% of average earnings.
Edward Prescott argues for compulsory retirement savings account albeit with important twists because it is otherwise irrational for many to save for their retirement against the background of a welfare state:
The reason we need to have mandatory retirement accounts is not because people are irrational, but precisely because they are perfectly rational — they know exactly what they are doing.
If, for example, somebody knows that they will be cared for in old age — even if they don’t save a nickel — then what is their incentive to save that nickel? Wouldn’t it be rational to spend that nickel instead?
…Without mandatory savings accounts we will not solve the time-inconsistency problem of people under-saving and becoming a welfare burden on their families and on the taxpayers. That’s exactly where we are now.

The Las Vegas population doubled in the 60s doubled again between 1970 and 1990 and almost doubled again by 2000.

Between 1990 and 2000 despite the doubling of population, housing prices only increased by 25%.

Land supply must be pretty easy in Las Vegas at least up until 2000.
