I cannot believe that starvation and apathy could coexist, so at some point the USSR's system must have prevented people from working for additional income, yes? In this case, the distinction between BI and communism becomes apparent: if the supply of labor falls below demand in BI, wages rise until people go back to work. Companies function as usual and are free to fire lazy workers. If food becomes more expensive, wages effectively fall until farmers can hire enough help (human or otherwise) to crank production back up again.
People considered working as some out of ordinary experience. For instance there were so-called "student construction squads" (строительные отряды, ССО) that consisted of young people, usually students, who toured the countryside and doing whatever construction work they could find (and there was a lot). This was a very well paid job and you could make a year of normal salary in a few months. People joined those to make enough money to buy new furniture or car etc. and after that returned to slacking off at their government job/study. There had been many more outlets like this so there were ways of getting reward for hard work. However very few entertained the idea of doing this full time.
The challenge is to create productive work for these people so that they can earn an income. Some of the Chinese 'make work' projects have been interesting in that regard but they are not a final solution.
What might be a more durable system would be to create a manufacturing plant that these folks could work in. It doesn't have to be complex, could be as simple as making cinder block for building construction. It has to be run as a business in the sense that standards are set and checked and people are paid based on their production. You have to be rigidly scrupulous about keeping corruption out of it, this is a lot harder than you estimate. Ideally the production is consumed in other projects. (like building buildings or railroads or other factories).
The core premise and compelling logic of BI comes from the fact that it is simple, not-gameable, and, most importantly, doesn't have huge disincentive effects at the margin as benefits phase out.
PER sounds like it runs headlong into all of those issues. By the standard you're using to critique BI using PER, I could just as well point to PER to critique markets as a whole.
There was obligation to work, unless you were sick. You could choose your trade, and if you were lazy/stupid/handicapped you were offered job that weren't demanding. Salaries were centrally planed, as was prices. The end effect was - less than 1% unemployement, huge drop in efficiency, no creativity boost to speak of.
I wonder if BI experiments suffer from observer bias - if the experiment was going bad it would be stopped, or at least people participating may think it would be. It's usually small community so they know who isn't working, and they can influence him.
If you were to introduce BI on huge scale, in a way that people take it for granted, I think the results would be much worse (and much more realistic).
People react to incentives. In the Soviet Union, "they pretended to pay us, and we pretended to work": although workers certainly received money in exchange for labor, increasing the amount of money you had did not typically increase the goods and services available to you, as the price system was so messed up that real prices were measured in waiting times and political favors.
A basic income avoids that trap because it leverages the distributed computation of the market to set prices. People will still be at least as entrepreneurial as they are now, because there's the opportunity for huge, outsized profits for both the entrepreneur and the provider of capital.
Also note that most salary workers nowadays make far in excess (typically 50k+) of what the minimum income would provide (on the order of 10k). Most of us here could work for a year, survive on what the minimum income would provide, and then have enough savings left over for nearly another decade at minimum income levels. But we don't do that, because we want more, and that wouldn't change with a minimum income.
I try to follow BI, and although the BI experiments I've heard of certainly have had cons to go along with the pros (spiraling costs in Manitoba, for instance), "stagnation" has never been one. I'd love to see that study.
[1] They eventually moved to Brazil instead.
The abstract suggests that it is looking at means tested and conditional benefits, including programs to "guarantee a minimum income": that should not be confused with a basic income, despite the similarity in terminology.
In the literature when people refer to a guaranteed minimum income they're referring to the government supplementing a person's income up to some predefined level. This makes it significantly cheaper than a basic income, because people who "don't need it" aren't receiving the income; but a really nasty side effect of that, as with nearly all welfare programs, is that it creates incredibly steep effective marginal tax rates. The simplest design--looking at someone's income, and filling it up until it hits the desired minimum--in fact leads to a 100% marginal tax rate, because a dollar earned from work is a dollar lost in benefits.
This means there's absolutely no incentive to work before you've made the minimum; contrast it to the unconditional basic income, where even someone who's only capable of producing half the value of the basic income is fully incentivized to do that work. So you avoid the deadly (literally!) welfare trap where the government actively punishes you for finding work.
I recognize the difference between BI and GMI as strategies but just so you know they are often both talked about in the same papers as they are both approaches to putting capital to work effectively amongst the poorest.
There aren't zero parallels to the USSR, but it's really not going as far, and I expect the human responses to be different.
I am aware that the BI proponents believe that jealousy is a stronger drive than apathy. And this is undoubtedly true for some fraction of humanity. I just think they overestimate how big is this fraction.
I admit my understanding is somewhat shallow, but I think the problem with the USSR had at least as much to do with price controls as any cash transfers. In a capitalist system with BI, if there's a labor shortage the wages paid to labor will increase and the price of goods will increase accordingly, and people will be motivated to take those jobs as the BI payments shrink in purchasing power. The HUGE advantage is that when there is a labor surplus, those people that remove themselves from the work force (voluntarily, involuntarily, or semi-voluntarily) still play a role in aggregate demand.
This phenomenon is not very noticeable on small scale (both in population and time). So I'd recommend paying a closer attention to the USSR history and being a bit critical to the "we overspent them" or "they did not do socialism right, duh" explanations. In my opinion, if it's been possible to overspend a superpower that had its own spaceships then overspending small fry like Libya, North Korea or Iran would not take any time at all. And free market just does not work when people have their basic needs covered. There also had been very small free market in the USSR and it was so small not because communists had been screwing with it (at least not more than the western governments screw with their markets), it's been small because most people just ignored it. If they could not find something in the government store then they would not buy it, even if they could afford the free market price.
Those in the USSR didn't suffer only the meeting of their needs, but also a constraining of their hopes; the cultural mythology glorified the state, not individual achievement; quotas frequently lead to poor results; and, quite importantly, I would expect that outright oppression contributes something to the breaking of a people - I believe there were several examples of groups taking initiative to better their lot and winding up dead, which seems strong incentive not to try.
What actually contributed to the "fall" of the USSR is a somewhat orthogonal question. A decline in worker efforts certainly might have contributed. I've been under the impression that a significant problem was the politicization of scientific and economic questions, in ways that just didn't square well with reality - I know that in particular they were slow to take up computers, and an ideological commitment to Lamarckian evolution lead to poor agricultural planning.
When they started - they've got a boost in productivity, even higher than the article describes. They've built up quite a lot in the 1920s-1930s. However, as the workforce become filled with the generations that took this system for granted, its effect turned into the opposite direction and by 1970s, as the last pre-revolutionary generation retired, there had been very few people left who actually wanted to do anything productive. The country went along for a while selling oil and other natural resources but the oil prices dropped in 80s and that was the end of it. There was just not enough oil any more to feed the whole country of 250M people.
