Thomas Paine, Napoleon and Martin Luther King don't have much in common at first glance. Nor do socialists and libertarians – or Finnish bureaucrats and Silicon Valley tycoons. Some policies have a habit of creating strange bedfellows, but none more so than the idea that governments should guarantee their people a minimum level of income. Not by creating jobs or providing traditional welfare, but by cutting checks, for the same amount, to everyone.
Universal basic income is an old idea, but in recent years it has gained considerable momentum. The threat of automation is focusing minds: Algorithms are learning to perform a growing range of blue- and white-collar jobs, and soon there may not be enough paid employment to go around.
Some basic income proponents, however, reject or ignore this doomsday scenario. "I appreciate that argument," Basic Income Earth Network (BIEN) co-chair Karl Widerquist told Investopedia in February, "but I'm worried about overstressing it." He prefers to frame the policy in terms of fundamental justice: "I support basic income because I believe it's wrong for anyone to come between someone else and the resources they need to survive."
What Is a Basic Income?
In its purest form, a basic income is an unconditional, periodic cash payment that the government makes to everyone. It is not based on means testing: A hedge fund manager and a homeless person receive the same amount. It has no strings attached, meaning it carries no requirements to work, attend school, receive vaccines, register for military service or vote. It is not paid in kind – housing, food – or in vouchers. It is a floor below which no one's cash income can fall.
Questions about how to actually implement this policy abound. Would it be taxable? (Probably not.) Mortgageable? (Jury's out.) And who constitutes "everyone"? Would a basic income be limited to citizens or would other residents – such as the millions of undocumented immigrants who live in the shadows in the U.S. – receive the benefit?
Where Does the Idea Come From?
In a strict sense, the intellectual history of universal basic income is around half a century old. But the idea that the government should somehow prop up everyone's earnings has cropped up repeatedly over the past two centuries: as a citizen's dividend, a social credit, a national dividend, a demogrant, a negative income tax, and a guaranteed minimum income (or "mincome"), among other concepts. Few of these proposals fit the usual definition of a basic income, and they differ from each other significantly. But they share a common thread.
The Erosion of Income Security
For much of human history, it was assumed that society would provide a basic standard of living for those who could not provide for themselves. Hunter-gatherer societies – the only kind around for nine-tenths of Homo sapiens' existence – were bound together not just by kinship networks, but by overlapping systems that followed the same logic. If a !Kung forager in the Kalahari met someone with his sister's name, he was expected to treat her like a sister, her son like a nephew and so on. Inuit men were tied to lifelong meat-trading partners, to whom they gave a cut of each seal they killed. No one lacked for family.
Agriculture and urbanization whittled such networks down to the nuclear family or even the individual. The larger institutions that took their place – church, state – left gaps. These shifts occurred over centuries, so few noticed, except when cultures on either side of the change collided. Charles Eastman was born Ohiyesa to the hunter-gatherer Sioux in 1858 and was horrified by the deprivation he saw in Victorian Boston:
"We knew well what it is to endure physical hardship, but our poor lost nothing of their self-respect and dignity. Our great men not only divided their last kettle of food with a neighbor, but if great grief should come to them, such as the death of child or wife, they would voluntarily give away their few possessions and begin life over again in token of their sorrow. We could not conceive of the extremes of luxury and misery existing thus side by side."
Thomas Paine and Henry George
Encounters between egalitarian societies and complex, unequal ones led people in the latter to consider a basic income more than once. Thomas Paine, an intellectual architect of the American Revolution, was struck by the Iroquois' way of life (they were farmers, not foragers) and made an effort to learn their language. In 1795 he considered the toll that "human invention" had taken on society. "Cultivation is at least one of the greatest natural improvements ever made," he wrote, but
"...it has dispossessed more than half the inhabitants of every nation of their natural inheritance, without providing for them, as ought to have been done, an indemnification for that loss, and has thereby created a species of poverty and wretchedness that did not exist before."
Paine proposed that a "groundrent" of £15 be paid to every individual upon turning 21, followed by £10 every year after turning 50. He argued that "every person, rich or poor," should receive the payments "to prevent invidious distinctions." Napoleon Bonaparte was sympathetic to the idea, but never implemented it.
A century later Henry George, an American economist active after the Civil War, called for "no taxes and a pension for everybody" via a public land fund. He was influenced by Paine and cited Sioux chiefs' astonishment at visiting East Coast cities to witness "little children at work."
The Last 100 Years
In the 20th century, the basic income cause was taken up by the left. Huey Long, a populist senator from Louisiana, proposed a minimum income of $2,000 to $2,500 in 1934 (as well as a maximum income of 300 times the average). G.D.H. Cole, a political economist at Oxford, advocated a "social dividend" as part of a planned economy. In 1953 he became the first to use the phrase "basic income."
In the 1960s – perhaps coincidentally, as anthropologists were documenting the !Kung and other fast-fading hunter-gatherer cultures – the idea of a guaranteed minimum income entered the political mainstream. Martin Luther King endorsed it. Experiments were run in New Jersey, Iowa, North Carolina, Indiana, Seattle, Denver and Manitoba. Nixon pushed to make it federal law, though he insisted that his "basic Federal minimum" included work incentives and so was different from the $1,000 annual "demogrant" George McGovern would have given to every citizen.
The political winds shifted, and the idea of a basic income hunkered down on the far left during the Reagan-Thatcher era. Market socialists weighed its merits against those of other fringe proposals, such as a coupon-based stock market that all citizens would own dividend-paying shares in, without the option to cash out. The occasional proponent from elsewhere on the political spectrum cropped up, including the self-described "Old Whig" Friedrich Hayek.
Imagining a 21st Century Basic Income
Today the idea of a basic income has again entered the mainstream. Unsurprisingly, given its scattered lineage, boosters make different arguments from diverse ideological vantage points. Broadly speaking, proponents on the left see it as an antidote to poverty and inequality. On the right its appeal has more to do with increasing the efficiency of the welfare state.
Another distinction, which cross-cuts left and right, is between reformers who want to rationalize policy in light of current issues and futurists who aim to radically overhaul society – or save it from radical overhaul due to automation. In practice, any given basic income proponent is likely to employ several of these arguments, without regard for political taxonomies.
Here's how these ideas play out across the spectrum.
One group of basic income supporters is mostly concerned with addressing problems with the status quo: mending a broken welfare system, reducing the stigma associated with public benefits, or cutting back on bureaucratic inefficiency.
Fix Welfare's Perverse Incentives
The existing welfare model has often been criticized for creating perverse incentives: for encouraging recipients to act in ways that the programs' designers never intended, or that offend against common sense.
In their recent book, "Basic Income," Philippe van Parijs and Yannick Vanderborght pick up this critique, arguing that welfare ensnares beneficiaries through means testing and work requirements, and needs to change. The "employment trap" keeps recipients from leaving a job, whatever treatment they receive, for fear of losing benefits. Bad employers therefore receive a subsidy in the form of a guaranteed pool of labor with no leeway to negotiate for better pay or conditions.
Ironically, welfare also produces an "unemployment trap." Some programs in effect tax welfare recipients' additional earnings at a 100% marginal rate: Earn a dollar from work, lose a dollar in benefits. The rate can even exceed 100% – a "welfare cliff" – making work a glaringly irrational choice:

Finland began a two-year basic income experiment in January in an attempt to counteract the unemployment trap. The country's welfare office sends €560 ($581) per month to 2,000 randomly selected working-age unemployed people. These will not lose the benefit if they start working, and the experiment will not affect their eligibility to receive unemployment insurance in excess of the basic income.
Perverse incentives also tear at social bonds. The now-defunct Aid to Families with Dependent Children program was notorious for encouraging families to separate. James Tobin, who pushed for a guaranteed minimum income to be paid to male heads of household, wrote in 1966, "Too often a father can provide for his children only by leaving both them and their mother." Van Parijs and Vanderborght call such incentives the "loneliness trap."
Provide Dignity for All
Welfare's current design undermines recipients' dignity. Means-testing is often invasive. Van Parijs and Vanderborght mention the Belgian government's monitoring of gas and water bills in an effort to root out cohabitating beneficiaries who pretend to live alone, which would entitle them to higher benefits (the loneliness trap again).
The payment of in-kind benefits, as opposed to cash, implies that recipients do not know what they need and cannot be trusted to spend money rationally. Secondary markets allow beneficiaries to sell non-cash handouts; the margin on such transactions represents wasted taxpayer money. Cash payments can also be subject to paternalistic conditions: a 2015 Kansas law (H.B. 2258) bars recipients of Temporary Assistance for Needy Families – a federal cash grant – from using the benefits to buy tattoos, movie tickets, manicures or lingerie.
Welfare itself carries a heavy stigma. Maria Campbell, a Canadian métis, wrote in 1983 that a friend admonished her to "act ignorant, timid and grateful" on her first visit to the welfare office: "They like that." Campbell, wearing her friend's ragged "welfare coat," described feeling "humiliated and dirty and ashamed." Proponents argue that a universal benefit would remove the need for recipients to grovel.
Universal benefits are also perceived as more politically durable. "There's an old saying that benefits for the poor tend to be poor benefits," Widerquist says, adding that Social Security "has remained strong while other parts of the U.S. system that are supposed to be for the needy – whoever we determine to be needy they somehow vilify them and then cut the program." Even universal benefits can be vulnerable, however: Alaska's governor recently cut the state's oil-funded dividend in half.
'Strike a Grand Bargain'
On its face, a universal government handout hardly seems compatible with conservative libertarianism. Charles Murray is most famous for "The Bell Curve," a 1994 book arguing that welfare is unproductive, since the root cause of poverty lies in racial disparities in intelligence. In light of these views, it is surprising to hear him join ranks with MLK and advocate for what looks like an extreme version of welfare.
"A libertarian dream of dismantling the welfare state is not in the cards," Murray told the Cato Institute, a right-libertarian think tank that is sympathetic to the idea of a guaranteed income, in October. Rather than fighting a losing battle, he would "strike a grand bargain with the left" and consolidate the 100-plus federal antipoverty programs into one cash payment. A universal basic income "will do the good things I claim only if it replaces all other transfer payments and the bureaucracies that oversee them," Murray wrote in June. (Some proponents to Murray's left, such as van Parijs and Vanderborght, favor keeping some existing welfare programs to supplement a basic income.)
The Federal Welfare System

Milton Friedman, another conservative libertarian, argued that a negative income tax would remove welfare's incentives against work. While his proposal was not implemented, the earned income credit is based on the idea.
Reduce Waste and Corruption
The bureaucrats at India's Finance Ministry who would like to introduce a basic income are probably not motivated by a hatred of bureaucracy, but they share Murray's desire to reduce the government's role in distributing benefits because in India, these tend not to reach their intended recipients.
A 2011 lawsuit accusing government employees in Uttar Pradesh of welfare theft made international headlines. For years, the suit alleged, officials had siphoned off fuel and food intended for the poor and sold it on the open market; the plaintiff told the BBC that offenders had made perhaps $42.6 billion in the prior decade. The head of a local NGO told Mint in 2013, "about 35% of the state's 44 million ration cards are held by ineligible people who bribe crooked bureaucrats."
Other developing countries have experienced similar problems. A Brazilian study found that in 2000, 50% of unemployment insurance beneficiaries were working and earning 2.8 times unemployment benefits.
In many developed countries the rich receive more benefits than the poor, though this is sometimes by design, rather than a result of corruption: the highest-earning 20% receive a greater share of the average transfer than the lowest-earning 20% in South Korea, Hungary, Japan, Austria, Latvia, Luxembourg, Chile, Poland, Spain, Portugal, Italy and Greece, according to the OECD.
Reformers support a basic income in light of society's needs and problems as they stand. A second group, the futurists, looks further down the line. Some feel that current concerns pale in comparison to the threat of technological unemployment and offer basic income as a solution. Others welcome such societal overhaul and see a basic income as a cornerstone of an eventual utopia.
Techno-pessimists: Save the Future
Fears of machine-induced mass unemployment are as old as the power loom. The Luddites, whose name survives as a slur for the tech-averse, spent the 1810s smashing them, and David Ricardo fretted over "the substitution of machinery for human labour" in 1821. A century later the playwright Karel Capek applied the Czech word for corvée labor (robota) to a caste of artificial quasi-humans who decreased the cost of industrial production by 80%, then exterminated humanity.
The idea that our inventions will render us obsolete and dead has not panned out so far. Technology has enhanced human productivity, not replaced it. Until recently nearly everyone farmed; now fewer than 1% of Americans do, but they keep busy and the U.S. produces a food surplus. Yet Murray is not the only one arguing – seriously, despite the phrasing – "this time is different." Some of Silicon Valley's leading lights are backing a basic income to counteract the automation their sector is creating, including Elon Musk, who has called artificial intelligence "our biggest existential threat." Sam Altman, president of startup incubator Y Combinator, has announced a "large, long-term study" on a the effects of a basic income in Oakland.
A March 2017 study by Daron Acemoglu of MIT and Pascual Restrepo of Boston University found that each robot reduces local employment by 6.2 workers. Automation has been put forward as an explanation for the persistent gap between economic growth and wage growth in the U.S. since the 1970s:
Things are liable to get worse. A 2013 paper by Oxford's Carl Frey and Michael Osborne found that 47% of U.S. employment is at risk of computerization. The most vulnerable jobs are hardly confined to the factory floor. Professions facing a 90%-plus probability of algorithmic obsolescence include tax preparers, waiters, paralegals, loan officers, credit analysts and 166 others. Algorithms already outperform doctors at diagnosing certain ailments, and autonomous vehicle prototypes are breathing down 5 million professional drivers' necks. (See also, Can a Robot Do Your Job?)
One solution would be to grow out of these problems, producing twice the output rather than laying off half the workforce. That is a tall order – the IMF projects that advanced economies will grow 1.9% in 2017 and 2.0% in 2018 – but even if it's possible, it's potentially dangerous. Climate change already threatens to drive millions of refugees away from rising seas and spreading deserts. The planet could buckle under a carbon-intensive doubling of global GDP.
Other futurists look at the prospect of mass unemployment and wonder what all the fuss is about: When robots shuttle dinner from kitchen to table or travelers from airport to hotel, are they yanking waiters' and cab drivers' livelihoods away – or liberating them from tedium? Arguably the latter, if they receive a basic income sizeable enough to live comfortably, and especially if they use their newfound free time in creative and socially beneficial ways.
In 1930, John Maynard Keynes articulated a utopian vision of "technological unemployment." He argued that we would leave behind "the struggle for subsistence" and that work would cease to be a necessity, though "for many ages to come the old Adam will be so strong in us that everybody will need to do some work" – perhaps 15 hours a week – "if he is to be contented." Labor's obsolescence would not just free up time and energy, but be morally uplifting:
"I see us free, therefore, to return to some of the most sure and certain principles of religion and traditional virtue – that avarice is a vice, that the exaction of usury is a misdemeanour, and the love of money is detestable."
Keynes did not mention a basic income, assuming instead that standards of living would rise inexorably until, around 2030 or so, his languid utopia would materialize. There is still time, but some proponents believe a basic income could hurry the process along. They see creative people, freed from the need to take jobs they don't want, contributing artistic, entrepreneurial and spiritual vitality to society.
In his 2017 Harvard commencement speech, Mark Zuckergberg said, "we should explore ideas like universal basic income to make sure that everyone has a cushion to try new ideas," stressing that if he hadn't been "lucky" enough to enjoy free time and financial wiggle room, he couldn't have founded Facebook Inc. (FB).
Basic income proponents also see a recognition – even if only implicit – of women's largely unpaid work.
Van Parijs and Vanderborght, borrowing a phrase from Rousseau, sum up the utopian view of a basic income: It is "the instrument of freedom," of "real freedom for all and not just the rich."
Could a Basic Income Work?
Not everyone is sold. Bill Gates told a Reddit AMA in February, "Even the US isn't rich enough to allow people not to work. Some day we will be but, until then, things like the Earned Income Tax Credit will help increase the demand for labor." His remark sums up the two main criticisms of a universal basic income: that it would be ruinously expensive, and that it would reduce or eliminate incentives to work. Proponents challenge both of these assumptions, but a lack of empirical evidence for a basic income's effects means the debate is mostly speculative.
Could We Afford a Basic Income?
Whether a given country could afford a basic income depends on the size of the payment, the design of the program – whether it replaces or supplements other welfare programs, for example – and the country's fiscal situation. Addressing the first issue, Widerquist points out that basic income is just that: "It's basic. It gets you a basic level, it doesn't get you great luxury." Some proponents – particularly those worried about mass unemployment – say that a basic income should be enough to live on, but others think it would be necessary to top it off with additional income, if only because states could not afford to pay a living wage to every citizen.
Estimates of what governments could currently afford appear to indicate that a realistic basic income would be modest. The Economist calculated the amounts that 34 OECD countries could pay if they scrapped all non-health transfer payments; the OECD mostly consists of rich countries in Western Europe and North America. The most generous hypothetical benefit comes from Luxembourg, which – with its $100,300 GDP per capita – could afford a $17,800 annual payout. Denmark, with its tax take of 49.6% of GDP, comes in second with a potential payout of $10,900. In a May 2017 report, the OECD itself concluded that funding a basic income at "meaningful levels" would require "further increasing tax-to-GDP ratios that are currently already at a record-high in the OECD area."
The U.S. could pay $6,300 at current tax rates. To afford a $12,000 payout ($60 short of the federal poverty line), it would have to increase its tax take by 10% of GDP.
Switzerland held a referendum on a basic income proposal in June 2016, and it received just 23.1% support. Part of the reason the measure was voted down was its perceived unaffordability. The ballot did not specify an amount, but campaigners mentioned 30,000 Swiss francs, or $29,900.
A Little Goes a Long Way
There is evidence that even small payments are beneficial. Brazil's Bolsa Família, a conditional cash transfer program, has reduced poverty despite paying just 178 reais ($57) per family per month on average. Families with per-person incomes of less than 170 reais ($54) are eligible, and 13.6 million receive benefits. Alaska's annual Permanent Fund Dividend, which is financed by oil revenues, topped out in nominal terms at just $2,072 in 2015, but a 2010 study by the University of Alaska's Scott Goldsmith estimated that it added around $900 million per year in purchasing power – roughly equivalent to the state's retail sector.
Basic income has been put forward as a way to smooth the earnings of the "precariat," an emerging class of freelancers, temporary contract workers, interns, and other rich-world workers – some of whom are highly educated – with precarious relationships to the labor market. Standing argued in 2010, when Uber and TaskRabbit were in their seed rounds, that a basic income would be an "egalitarian way of reducing economic volatility" that could help the rich world avoid a "politics of inferno."
Some proposals would sacrifice strict universality in the name of affordability. India is mulling a "quasi-universal" basic income of 7,620 rupees ($118) per month; the government estimates that, to be workable, it can only be paid to around 75% of the population. Proposals to limit uptake include naming and shaming and means testing based on ownership of assets such as cars and air conditioners.
Van Parijs and Vanderborght allow that a basic income would be expensive, but "there is cost and there is cost." For many households, they argue, higher taxes would come right back to them as basic income, with little net difference to their finances. For others a basic income would raise or lower after-tax earnings significantly, but the authors argue that redistribution is different from spending on "real resources," since it "does not make the population as a whole either richer or poorer."
On the other hand, the OECD found that a "large majority would see either significant gains or large losses" in income if a revenue-neutral basic income were introduced.
Tax the Robots
The above considerations assume that society retains approximately its current form. But if mass technological unemployment does occur, Bill Gates and others have proposed taxing the robots. Gates is skeptical of basic income and sees the tax as a way to "slow down the speed of that adoption somewhat to figure out, 'OK, what about the communities where this has a particularly big impact? Which transition programs have worked and what type of funding do those require?'" But the revenues could in theory fund a basic income, as Benoît Hamon, France's Socialist candidate for president in 2017, has proposed. (He was eliminated in the first round of voting, with just 6.4% of the vote.)
Would People Stop Working?
The Death Spiral
In a 2014 working paper weighing a basic income against traditional unemployment insurance, economists at the St. Louis Fed projected that voluntary unemployment would rise rapidly as a basic income's amount rose. Voluntary quitting would in turn raise the tax burden on workers needed to fund the payout, encouraging more people to drop out of the workforce: "The likelihood of quitting rises exponentially in response to increases in UBI [universal basic income] benefits." However, the authors argue, a basic income of $2,000 (2011) or so is "clearly sustainable."
The Manitoba Experiment
The closest approximation we have to data on the effects of a universal basic income comes from the "Mincome" experiment, in which two groups of Manitoba residents received a guaranteed minimum income from 1974 to 1979. One of these, the rural town of Dauphin, was a "saturation site": everyone received the benefit. Politicians soured on the project and it wrapped up without producing a final report, but economists in the 1980s found that secondary earners worked less, while primary earners barely altered their behavior.
In 2011 Evelyn Forget of the University of Manitoba compared these findings to health data to try to pinpoint why. She found that two groups in particular worked less, married women and young men. "Married women tended to prolong the period they were out of the workforce when they gave birth," Forget told Investopedia in February, in effect "using the stipend from income to buy themselves longer parental leave." As for young men, "what we found was a pretty dramatic increase in high school completion rates in Dauphin during that period compared to the rest of rural Manitoba."
Breadwinners did not quit their jobs to indulge in drinking or other odious extracurriculars. In fact these may have declined. Hospitalization rates fell 8.5% relative to the control group, led by accident injuries, which encompass "work accidents and farm accidents, car accidents, family violence," according to Forget.
On the other hand, four roughly contemporary negative income tax experiments in the U.S. found that primary earners were responsible for one third of a 13% reduction in working hours by families as a whole. These results contributed to the decline in political support for guaranteed minimum income schemes; a (spurious, we later learned) increase in divorce rates among black families did the rest.
Anthropologist David Graeber draws comparisons between a basic income and an existing institution that gives 2.2 million Americans the opportunity not to work:
"I always talk about prisons, where people are fed, clothed, they've got shelter; they could just sit around all day. But actually, they use work as a way of rewarding them. You know, if you don't behave yourself, we won't let you work in the prison laundry. I mean, people want to work. Nobody just wants to sit around, it's boring."
People may not always opt to work in the traditional sense of the word, however. Graeber gives the example of a poet-musician friend who became a corporate lawyer. With a basic income, he would not be idle, nor would he be working a traditional full-time job. Speaking to Freakonomics, Forget pointed out that "gentlemen of leisure" were responsible for many of the scientific breakthroughs of the 18th and 19th centuries.
Such arguments also find traction on the right. Murray points out that his wife, who holds a Ph.D. from Yale, does not work for pay, but "is busy all day long with half a dozen different useful organizations." By encouraging such contributions, he says, a basic income could "revitalize American civil society."
What's So Great About Work?
Even if people did decide not to work upon receiving a basic income, would that be so bad? Strains of thought on both the left and right see work as conferring dignity and as a good in itself. Many on the right see it as teaching self-reliance – if not conferring inherent spiritual merit. Many on the left see it as necessary to build solidarity among workers.
But there is evidence that humanity's natural condition is positively indolent. Anthropologists in the 1960s found that foraging groups such as the !Kung spent around 20 hours per week obtaining food, compared to our accustomed 40-plus. Adding in foragers' other chores yields something closer to 40 hours, but workers in advanced economies do their cooking, cleaning and shopping off the clock.
If we extrapolate these 20th-century foragers' regimen to earlier non-agricultural societies, our current enthusiasm for labor looks like Stockholm syndrome. For 90,000 years our ancestors worked bankers' hours; the hard slog only appeared in the last 10,000. Critics argue that such extrapolation is ridiculous: The anthropologists' data set is tiny and flawed, gathered during times of plenty from unrepresentative groups – and in any case, we shouldn't envy anyone who lacks modern dentistry.
Then again, if we were able to recreate that easy lifestyle – even if it were atypical – with added benefits, why shouldn't we?
Would a Basic Income Reduce Poverty?
It is not enough for a basic income to be harmless; it must also – bureaucracy-busting arguments aside – reduce poverty and, ideally, inequality.
Brazil's Bolsa Família program is encouraging in this regard. Beginning in 2004, the program has made modest cash grants to poor families who send their kids to school and the doctor. The country's poverty rate fell from 26.1% in 2003 to 14.1% in 2009; the extreme poverty rate fell from 10.0% to 4.8%. From 2007 to 2009, Bolsa Família is estimated to be responsible for 59% of the reduction in poverty and 140% of the reduction in extreme poverty (the rate would have risen otherwise). The Gini coefficient, a measure of inequality, fell from 0.580 to 0.538 from 2003 to 2009, in part due to Bolsa Família.
The development sector has begun to favor direct cash transfers over aid in kind. Having previously thought that recipients would waste the money, well-meaning benefactors realized they were hardly any better. Africa is dotted with broken water pumps whose donors made no provision to fix them. Cash aid, on the other hand, appears to work rather well. A 2013 study by MIT's Johannes Haushofer and Jeremy Shapiro found that unconditional cash grants made to Kenyan households by Give Directly cut the days children went without food by 42% and increased livestock holdings by 51%.
For some goals, however, adding conditions helps. Adolescent girls' school attendance in Malawi rose with no-strings-attached cash grants, but making school a mandatory condition for receiving payments had a much larger effect.
The OECD estimates that, in some rich countries at least, a revenue-neutral basic income would increase poverty. In countries such as Britain, those depending exclusively on transfer programs would see their benefits cut; whereas 2% of the UK's population would move out of poverty due to a hypothetical basic income, 7% would fall into it.
We May Soon Find Out
With luck, questions about the effectiveness of a basic income will be much easier to answer in the near future. For the first time since the 1970s, mainstream politicians and academics are enthusiastic about the idea, and a rash of experiments is being planned. In addition to Finland, Oakland and India, Ontario is running a trial.
Until these results become available, a universal basic income will remain an uncertain but tantalizing prospect. Could doing away with poverty, sweeping away patronizing bureaucracy, neutralizing the threat of mass unemployment and increasing the value society places on worthwhile, but unprofitable, pursuits really be as simple as handing everyone cash?
