'' Assuming a government’s intention is to wind back its contribution to demand in the economy (via government spending) through . . .
This is meaningless jibber-jabber. There is no such thing as a "contribution to demand in the economy," because there's no need for any such contribution. You "contribute" to satisfying a need, not increasing any "demand" in the economy. The only "contribution" needed is to satisfy the existing demand, not to contribute to increasing the demand. The economy has no need for any increased demand, but only for satisfying the existing demand.
I.e.,
don't INCREASE the demand, just satisfy the existing demand.
In the case of government, the need is to meet the need for infrastructure, etc., or public demand for certain services. So government satisfies some of this demand, but there's no need for government to increase any demand, or create more demand for anything.
. . . through what is euphemistically termed “fiscal consolidation”, and assuming our trade is not significantly changing, a certain real wage growth is required to generate sufficient growth in demand to warrant . . .
No, there's no need for any "growth in demand" for anything, for any purpose. There is no need for demand itself. There is only need for the stuff demanded, like better roads, a bridge, etc., but no need for any demand, or to increase the demand.
. . . to generate sufficient growth in demand to warrant sustained investment and productivity growth.
No, there's no need to "generate sufficient growth in demand" -- that's Wackodoodle pseudo-economics. It's not DEMAND that there's a need for.
If productivity growth takes place in order to meet existing demand, there's no need for government to do anything about it. There's no need to somehow increase the demand for something, for any purpose, such as "warrant sustained investment" or other babble. No, just build the needed roads, etc., not to generate new demand, but rather to just meet the public need, like for transportation, etc. Meet the existing demand, yes, but don't generate any demand per se. There is no need for "demand" per se.
It’s the flipside to this scenario that is worrying. To the extent that increasing profitability through increased productivity is not shared in the form of increased real wages, the economy faces the danger of its productive capacity growing faster than demand. This kind . . .
No, there's no need to increase wages for such a silly meaningless purpose as this. The only need to increase wages is to attract needed workers, to get the needed work done, not to get the demand growing faster.
There is no need to make the demand grow faster. That is wacko phony babble barf Snake Oil Economics.
If too much stuff gets produced so it doesn't get bought by anyone, then whoever produced it loses, because they wasted their investment by spending it on unnecessary production. The solution to overproduction is to let the market punish the producers who produced the unnecessary stuff that couldn't be sold, not to create extra demand for the stuff that should not have been produced.
This kind of danger was highlighted long ago by the noted Italian economist Luigi Pasinetti.
Many "noted" nutcase Snake Oil Economists have preached the same barf. Just because this one is Italian doesn't make it any less wacko -- we'll call it Spaghetti-Brain Economics in his case. It's still nutcase, whatever their race or nationality is. There is no such thing as a need for more demand.
In this scenario the profit of each unit of output may increase initially as productivity grows, but demand does not keep pace, in which case the increase . . .
-- in which case let the producers lose on their investment for producing stuff there wasn't any demand for. It's very simple. Let the market punish those uncompetitive producers who made the bad decision to produce that stuff. Meanwhile the good producers who did meet the existing market demand will do just fine, making more profit and getting rich for doing a good job. But those who wasted their capital on stuff no one would buy should be punished by the market.
. . . in which case the increase in profitability is likely to be short-lived.
Yes, for the uncompetitive ones who produced something that would not sell. That's fine, for them to lose. But for the good producers who made good decisions, their profitability will do fine, and they will prosper, despite someone else's decreased profits because of their bad decisions. Good production = those companies continue to profit despite unprofitability of the bad companies. So profitability of those good producers is NOT short-lived.
More worrying in this case is that employment growth suffers and consequently the unemployment rate is likely to rise.
Not if employers are allowed to hire cheap labor = lower labor cost = more hiring and more profitability due to the cost savings.
Some economists would counter that real wages would fall in order to absorb any increased unemployment, though this claim has always been contentious.
Allowing wages to fall, according to the (lower) demand, always means increased employment. And they can never fall below the level necessary to attract the needed workers, so the needed work will get done, which is all that matters.
It supposes that unfettered markets will always provide demand for whatever amounts of goods and services are produced – in itself a controversial position in economics.
It's all wackodoodle economics, because there is no need to "provide demand" for anything. If "goods and services are produced" which there was no demand for, then whoever produced them should be punished by the market for those bad decisions. It is wrong for them to produce something that won't sell. It's wacko nutball economics to "provide demand" for anything. If there's no demand for the stuff, then don't produce it. Or let the "unfettered market" punish the jerk who produced it. No need for the government to worry about it.
Of course, none of this deals with the moral or ethical imperative of a minimum wage which ensures a liveable real wage.
And makes everyone worse off, by causing less to be produced, and causing many to be unemployed who would otherwise do needed work at low wages. There is no moral or ethical imperative to do this. The imperative should be to IMPROVE people's lives, not make them worse as minimum wage makes more people worse off, by driving up cost and prices and reducing production.
Rather, the point here is that, quite aside from the moral or ethical case, there are economic arguments to be had for ensuring an appropriate rate of growth of real wages.''
That's exactly what the "unfettered market" does, without the government interfering. Because as more work is needed, the wages rise as needed in order to attract the needed workers, but not rising higher than this, so that the labor cost does not increase more than needed, so we get the maximum needed production at the most reasonable cost = all consumers are better off = the nation is better off.
