Cash and Income Studies: A Literature Review of Theory and Evidence

Introduction

What happens when you give people cash? How do they use the money, and how does it change their lives? Every cash study on this list is different: the studies vary in intervention type, research design, location, size, disbursement amount, and effects measured. The interventions listed here include basic income and proxies--earned income tax credits, negative income tax credits, conditional cash transfers, and unconditional cash transfers. The variety present here prevents us from being able to make broad claims about the effects of universal basic income. But because of its variety, this review provides a sense of the scope of research in the field, capturing what kinds of research designs have been used, and what effects have been estimated, measured, and reported. The review also allows us to draw some revealing distinctions across experimental designs.

If you’re interested in creating a UBI policy, there are roughly three levels of effects (after ODI) that you can examine. On the micro level, you can scrutinize what happens to individuals and households that receive a transfer, e.g., how does children’s schooling change, how does consumption change? On the meso level, you can explore how groups of households or villages, community organizations, and community institutions change in response to a saturated transfer effect. The third level, macro, is the golden question of UBI research, but also the hardest to address: what does UBI do at the size of a province or nation? We’ve included the Levy Institute model as a starting point for macro-analysis. But this literature review mainly looks at what these studies reveal to be the micro and meso level effects, economic and social, including effects on schooling, health, crime, and labor markets.

What trends can we draw from these studies? This won’t be a surprise: overall, cash increases consumption.

Perhaps more surprising to UBI skeptics, the research overall does not show that cash transfers drastically lower labor supply by decreasing motivation to work. The negative effect of cash on labor supply is moderate if present at all. As a whole, the research also does not show that recipients of cash transfers are spending on temptation goods--rather, they’re putting the money into smoothing consumption, like increased food security and purchases of durable goods.

Beyond that, one intriguing meta-research trend is how few of these studies address labor market effects, and how broadly they define the labor market effects. Most of the studies look at overall labor market equilibrium at most, and do not delve into a more nuanced analysis of, for example, number of hours worked, people moving in and out of full-time jobs and contract work, changing types of work, changing quality of life, and so on. Only one paper on the conditional cash transfer program in Mexico in the list covers these areas with nuance. We hope to see more comprehensive research on labor effects of a basic income in the future.

As you read through this informal draft of what will become a formal academic review, we want to draw your attention to a few useful distinctions: note differences between micro, meso, and macro level effects; differences in interventions; how different studies measure different effects; and the differences in the evidence from pilots in developing and developed world. Finally, there is a distinction between short-term cash interventions and long-term cash interventions--pilots that gave people money for a year, or decades, or indefinitely. We’ve included literature pertinent to both effects, but it’s important to note that this evidence is relevant to UBI, as ideally conceived, only partially, since a UBI would involve an indefinite disbursement of a transfer to cover minimum standards of living for a population.

Universal Basic Income

Universal basic income is one of several terms used to describe a system of regular and unconditional direct cash payments for all individuals in a given country or region. There are three important criteria which a basic income usually satisfies. First, it is given universally within a predefined community, which means treatment is not means-tested and is not meant for only a subsection of the community selected based on certain criteria. Second, the cash payments must be large enough to support a decent standard of living in the pre-defined community. Third, it usually constitutes a long-term stream of transfers to support the living needs of its recipients over a sizeable duration.

In recent years, a wide range of public, non-profit, and private actors have brought renewed attention to this concept, particularly its viability in the United States and other developed countries. The impact of a universal basic income is multi-dimensional—it can affect one’s consumption, work, physical and mental health, education and social relationships. It also has wide-reaching macroeconomic effects, potentially impacting economic growth, labor market outcomes and public finance.

We present here a list of papers and articles which touch on the various effects of and considerations behind designing and implementing a universal basic income. The pilots discussed in these paper usually fulfill (or come close to fulfilling) all three criteria of being a universal basic income. They vary by location and size, but taken together, these papers present some of the preliminary reported effects of a Basic Income.

  • Ravallion (2018) critically reviews both guaranteed income and guaranteed work from a policy perspective. With versions of the two rights-based policies in India as a case study, he argues that cost, targeting, corruption, and context variation across settings are central restrictions on unequivocal support of either policy in developing countries. In the case of India, Ravallion offers evidence that the country’s employment guarantee programs have been less effective at poverty alleviation than one might expect from a universal cash transfer program. He argues that the question of whether universal transfer programs will reduce poverty more than workfare or finely-targeted transfers is an empirical one that will vary across contexts, but suggests that the benefits of universal programs are worth consideration in certain settings.
  • The Alaska Permanent Fund has paid a yearly dividend to state residents since 1982. To study the impact of the fund on labor market outcomes, Jones and Marinescu (2018) compare Alaska with a synthetic control constructed from a weighted average of control states. They find that universal and permanent cash transfers do not significantly decrease aggregate employment. One possible explanation is that general equilibrium effects will offset the tendency for cash transfers to decrease labor supply.
  • Schulz (2017) argues that a universal basic income can help combat historical structural inequalities inherited by modern women by freeing women-led households from the vulnerability of poverty and their subsequent marginalization. The authors suggest that an additional source of income can also help balance unequal power relationships with male relatives and partners.
  • Using the Levy Institute macroeconomic model, Nikiforos, Steinbaum, and Zezza (2017) show that enacting a UBI and paying for it with increases to the federal debt would grow the economy. The model also shows economic growth if the policy were paid for with increased taxes on households.
  • Based on a review of the empirical results from U.S. and Canadian negative income tax experiments, the Alaska Permanent Fund Dividend, the Eastern Band of Cherokees casino dividend program, and other assorted studies on unconditional cash transfer programs, Marinescu (2017) finds no impact or a moderate decrease in labor participation. She finds additional effects in other quality-of-life benefits, such as improved mental and physical health, educational outcomes, parenting, and reduced criminal activity.
    • A model developed by the District of Columbia’s City Council in a policy and impact statement on Basic Income offered contrasting results. According to their simulation model, providing a minimum income that is equal to 100% of the Federal Poverty Level is detrimental to the District’s economic growth and employment. The effect is worsened when the minimum income provided is raised to 450% of the Federal Poverty Level. They recommend further study on how such a policy intervention can be funded.
  • Salehi-Isfahani and Mostafavi-Dehzooei (2018) study the effects of large scale cash transfer program in Iran starting in 2011, which distributed a fixed amount (amounting to 29% of the median per capita household income) of cash to all Iranians (with a 95% take-up). Using panel data and a difference-in-differences model, they find no evidence that cash transfers reduced labor supply, except among youth (20-29 years), where they find a negative effect. They also find that service sector workers increased their hours of work.
  • Calnitsky and Latner (2017) analyze the labor market effects of the Manitoba Basic Annual Income Experiment (Mincome) (1975-77) and report that the moderately sized basic income generated an 11.3 percentage point reduction in labor market participation, however this was largely driven by young and single-member household participants. They also note 30% of this reduction can be attributed to “social interaction” or “community context” effects.
  • Colombino (2015) argues that an unconditional basic income can redistribute the gains from automation and globalization, build a buffer against shocks and systemic risks, and generate positive labor supply incentives amongst the poor. While Colombino suggests a UBI is simple, he notes that financing it likely requires higher taxes, hence tax systems need to be carefully designed to avoid canceling the potential benefits of unconditional basic income through efficiency losses.
  • Assessing a study involving the distribution of a monthly basic income grant of NAD100 to around 1000 citizens in Namibia, Rigmar (2013) reports that the study lacked transparency and rigorous reporting, and the results raise concerns on the validity of the reported findings. Therefore, the experiment could not address questions about basic income in a political decision making context.
  • According to Forget, Peden and Strobel (2013), empirical evidence and social theories suggest that cash transfers not only affect individual decision-making but also impact how households interact within a community, hence it is important to understand the social impact of basic income when addressing questions on how best to design cash transfer schemes.
  • In the Manitoba basic annual income field experiment (Mincome) from 1974 to 1979, families with no income received 60% of the Statistics Canada Low-Income Cut-Off (LICO). Forget (2011) reports this resulted in an 8.5 percent reduction in hospitalization rates and reduced contact with physicians, showing that a relatively modest guaranteed annual income can improve population health and bring significant health system savings.
  • Akee et al (2010) assessed the effects of a universal cash transfer administered by Eastern Band Cherokee, and highlight that regular unconditional cash transfers led to the children of recipients achieving higher levels of education in their young adulthood and a lower incidence of criminality for minor offenses, likely attributable to increased stability and support in the home.

Earned Income, Earned Income Tax Credit, and Negative Income Tax

ExpandClose

A negative income tax (NIT) is a progressive tax where households whose income is below a predetermined level receive an income supplement. An earned income tax credit is a refundable tax credit for workers of low to middle income, which has a similar effect of creating a progressive tax system. These differ from a basic income as they are not distributed universally within a predefined community, and the transfer amounts depend on the income level of the household.

We include earned income studies in this review as the effects of a lump-sum increase in income can be relevant to understanding the effects of a basic income. One of the primary concerns economists have regarding a NIT is that it is distortionary and affects recipients’ incentive to work. Since unemployed individuals are ineligible for benefits, an NIT is thought to be better than a Basic Income as it still incentivizes households to work. On the other hand, some economists think that a NIT will reduce labor supply, since the magnitude of the benefit distributed varies negatively with the income level of the household. As such, many studies have been conducted to analyze what exactly is the impact of an NIT on labor supply and employment outcomes. Other studies have also documented economic, health and social effects of an NIT which policymakers should consider.

  • Using U.S. administrative prison release records released between 2000 and 2014, Agan and Makowsky (2018) use a difference-in-differences strategy to identify the effect of minimum wage increases and EITCs on recidivism. In their analysis on EITC, the availability of state top-ups to the federal EITC is associated with a 1.6 percentage point lower rate of recidivism amongst women, while having no significant effect on men.
  • Bastian and Michelmore (2018) examine the long-run impact of an EITC on children who were exposed to EITC variations by using EITC exposure as an instrument for family income. With data from the 1968 to 2013 waves of the Panel Study of Income Dynamics they find that an exogenous shock in the form of increased pre-tax income induced by a change in EITC policy increased educational attainment and employment in adulthood. Their reduced-form estimate suggest that an increase of $1000 in EITC exposure increases high school graduation and college graduation by 1.3% and 4.2% respectively for children exposed to the increase when they were between the ages of 13 to 18. It also raises the probability of them being employed by 1.0%. However, EITC exposure had no significant effects on children below the age of 13 conditional upon later exposure.
  • The EITC has been found to reduce poverty rates as well as improve health and education outcomes. However, for families with two or fewer children, the maximum credit distributed to them has remained the same in inflation-adjusted terms since 1996. As such, Hoynes et al (2017) propose to increase the EITC credit by 10% while maintaining its current structure so as to increase wages which have been stagnating, further increase employment, and bring about 600,000 people out of poverty.
  • Wiederspan et al (2015) argue that a negative income tax can help fill the gaps in current federal means-tested assistance programs. While past NIT experiments have led to a reduction in labor supply, the effects were not as large as often speculated, and time saved from work was spent on childcare and looking for work. Moreover, those experiments did not measure long-term, general equilibrium effects. The authors show that an NIT could be funded using expenditures from existing programs which it could replace, and if the marginal tax rate was chosen carefully. Finally, they assert that a NIT could be made more popular by appealing to moral values rather than focusing on the technical policy details.
  • The Earned Income Tax Credit (EITC) in the U.S. serves to offset the payroll taxes and supplement the wages of low-income workers, with payments concentrated in February and March when tax refunds are received. A 2008 study by Goodman-Bacon and McGranahan found that in 2004, the recipients concentrated most of their household spending in vehicle purchases and transportation spending in response to their EITC payments.
  • Based on a survey on five NIT experiments in Canada and the U.S. from 1969 to 1980, Widerquist (2005) concludes that labor market effects of negative income tax experiments are often overstated and misinterpreted, since without an estimate of the labor market demand response, researchers cannot estimate the overall market response.
  • Robins’s (1985) comparison of four negative income tax experiments sponsored by the US federal government between 1968 and 1982 found that a negative income tax led to a fall in labor supply by about the equivalent of two weeks of full-time employment for husbands, three weeks for wives and single female heads, and four weeks for youth.
  • A negative income tax led to an increase in the average reading achievement of children in grades 4 through 6, but did not have any observable beneficial effects for older children, according to this 1979 study.

Cash Transfers, Wealth Transfers, and Unearned Income

ExpandClose

This category lists papers which look at the impact of cash transfer programs which were excluded from the first section due to the nature (smaller amounts of disbursement) and size (smaller sample size) of the experiments. These cash transfers usually implemented by governments, NGOs or charities. A plethora of studies has been conducted to analyze how cash transfer programs affect economic, social, employment and health-related outcomes of households, and how various aspects of cash transfer programs, such as the program duration, magnitude of cash transfers and frequency of transfers can alter these effects. Some programs provide cash transfers with no strings attached, while others come with conditions that require recipients to take certain actions which will improve other aspects of their lives. In such programs, cash may be seen as an incentive or an enabler for recipients. Some studies also look at how cash transfer programs may have differential effects depending who in the household is a recipient of the transfer. These are all important considerations that need to be taken into account when designing a cash transfer program.

  • Using a two stage randomization design in a randomized controlled trial implemented by GiveDirectly, Haushofer and Shapiro (2013) found that unconditional cash transfers in Kenya led to a rise in food, medical and education expenditures, and a fall in expenditures on alcohol and tobacco. Cash transfers also resulted in large increases in the recipients' psychological well-being. Their research also suggests that households face savings constraints, since one-off lump-sum transfers tended to be spent on durables.
  • In the same experiment, Haushofer and Shapiro (2018) assess the economic and psychological outcomes three years after the beginning of the GiveDirectly cash transfer program in Kenya. The authors report that recipient households had 40% more assets than non-recipients in the same village, but there were no statistically significant effects in other outcomes. They also note spillover effects, wherein households affected by the spillovers have lower consumption and food security than pure control households. For detailed comments and discussions on this paper’s findings, click the following links from GiveDirectly, the World Bank, and CGDEV’s blog.
  • Kugler and Rojas (2018) assess the effect of the exposure to PROSPERA, a conditional cash transfer program, in Mexico on three education variables: educational attainment, high school education and at least one year of tertiary education, and five employment variables: probability of being employed, the number of hours worked per week, employment quality, likelihood of having an employment contract, the likelihood of having non-wage benefits, and hourly wages. After controlling for multiple hypothesis testing, the authors find significant and positive effects in all cases. The positive effects are however, weaker for women and children of illiterate women.
  • Noting that there are several potential channels via which a cash transfer program can affect labor supply apart from the standard income effect, Baird et al (2018) review a range of studies on conditional and unconditional cash transfers. They conclude that unconditional cash transfer programs, cash transfer programs with conditions unrelated to employment and remittances tend to have limited to no impact on adult labor. On the other hand, cash transfers for job search assistance and small business start-up usually increase labor supply likely by alleviating liquidity and risk constraints, although the effects via these channels cannot be isolated from those due to increases in human capital as well as other general equilibrium effects.
  • Akee et al (2018) examine the effects of cash transfers from the distribution of casino profits amongst adult Eastern Cherokee tribe members on child development. Using data from the Great Smoky Mountains Study of Youth, they find that an increase in unearned household income led to large positive effects on children’s emotional and behavioral health and positive personality trait development, especially amongst children who did not do as well as their peers in these aspects prior to the treatment. They also find that improved parental behavior and familial relationships was likely to be an important channel via which financial well-being may impact child development.
  • Angelucci et al (2017) study both expected income shocks brought about by the PROSPERA program and unexpected income shocks due to health and employment shocks. They find that an unexpected negative shock in income reduces labor supply, food security, mental health and healthful behavior but does not affect parenting, cognition, risk and time preferences, and aspirations about children's' educational attainment. On the other hand, an expected positive shock caused by a conditional cash transfer does not lead to any change in these outcomes apart from increasing disposable income.
  • Banerjee et al. (2017) studied data collated from seven CT/UCT/in-kind transfer studies in Africa and Asia and showed that cash transfer programs have no observable impact on one's propensity to work or the overall number of hours worked for both men and women.
  • Walker (2017) estimates the effect of exogenous positive income shocks to household income in Kenya on informal taxes and public goods provision. Using surveys of village leaders, and panel and experimental household data from a sample of participants who received a large one-time unconditional cash transfer in GiveDirectly’s RCT, Walker estimates regression models at household, village and sub-location level and reports no significant effects on the amount paid in formal taxes, nor on the informal tax rate. He notes a 2.4 percentage point increase in county tax payment which he relates to the fact that recipient households are more likely to be self-employed. There is also no attributable effect on public goods provision or the quality of public good provision, indicating no short run effects of the income changes on public good provision or informal taxation systems that can be attributable to the exogenous income shock.
  • Evans and Popova (2017) review the effects of cash transfers on temptation goods, defined as expenditures on alcohol and tobacco. Compiling 44 estimates from 19 studies on conditional and unconditional cash transfers in low- and middle-income countries from 1997-2014, they find with almost no exceptions either an insignificant effect or a significant negative effect of cash transfers on temptation goods. When they differentiate only the estimates from studies which had a randomized design, no estimate was reported to show a positive and significant effect on expenditures on temptation goods.
  • A systematic review of 201 studies by the Overseas Development Institute (2016) on both conditional and unconditional cash transfer published between 2000 and 2015 finds links to the following: reductions in monetary poverty, increases in total and food expenditure, increases in school attendance, increases in the uptake of health services, and increases in savings, livestock and agricultural ownership. The effect of cash transfers on employment outcomes remains unclear. Higher transfer levels are associated with larger impacts. Longer duration of exposure to cash transfers are linked to greater improvements in outcomes. Cash transfers conditional on certain behaviors more positively affect the outcome related to the behavior than in unconditional cash transfers.
  • Results from New York City’s conditional cash transfer program (2016) for families that received over $8700 on average over a three-year period show that the transfers reduced financial hardship, increased graduation rates for reading-proficient 9th graders who entered high school, and increased households' use of preventive dental services. It did not affect school outcomes for elementary and middle school students, the use of preventive medical services, and parents’ employment in or earnings from jobs covered by the unemployment insurance system.
  • Baird et al (2016) investigates the medium-term effects of a two-year, two-treatment arms cash transfer program to adolescent females in Malawi, where one treated group received cash transfers conditional upon school attendance while the other received equal-sized unconditional cash transfers. They found that while unconditional cash transfers led to reduced teen marriages, live births and HIV infections as well as improvements in psychological wellbeing at the end of the program, these effects were not sustained after two years. Their husbands had relatively lower cognitive ability, although their children born during the program had improved HAZ scores. On the other hand, those that received conditional cash transfers saw sustained positive effects on school attainment, teenage marriage and pregnancy incidences, and desired fertility. They were also more likely to be matched with husbands who had completed secondary school. There are however no gains in other outcomes such as earnings, consumption, health, empowerment and subjective well-beings.
  • Between 2010 and 2011, the Zambian government launched two unconditional cash transfer pilot programmes, described in this 2016 paper from Handa et al. The Child Grant Program (CGP) targeted all households with a child under three years old in three poor rural districts, while the Multiple Category Targeted Programme (MCP) was implemented in two rural districts and targeted vulnerable households such as those with a disabled family member, or those with a female or elderly head caring for orphans. Bimonthly transfers were made to each household irrespective of size, and this entailed a transfer of USD 24 per month in Purchasing Power Parity terms. ITT estimates made 24 months and 36 months into the study in nine domains, namely total consumption, food security, asset holdings, subjective well-being (relative poverty), income and revenues, finance and debt, material needs, schooling and young child anthropometry, show that that both the CGP and the MCP had statistically significant effects in almost all domains except for schooling and young child anthropometry for the CGP, and incomes and revenues after 24 months for the MCP (effects on young child nutrition were not measured for the MCP). A sizeable multiplier effect is observed given that households spent 59% more than the value of the transfer.
  • In a large-scale unconditional cash transfer program in Indonesia, Bazzi et al (2015) found that timely receipt of cash transfers do not yield expenditure changes relative to non-recipients, while delaying the delivery of the transfers reduces expenditures by 7.5%, suggesting that the impact of cash transfers depends on the timing of transfers.
  • Analyzing the long-run impact of the Mother's Pension program, a government-sponsored welfare program in the US (1911-1935), Aizer et al. (2014) found that male children of successful applicants lived one year longer, received one-third more years of schooling, were less likely to be underweight, and had higher income in adulthood compared to those of rejected mothers.
  • Kenya's Cash Transfer for Orphans and Vulnerable Children Programme (2014) involve a flat monthly transfer of KSH 1500 to ultra-poor families with orphans and vulnerable children aged 17 years and younger. The transfers increased food consumption coming from home production, accumulation of productive assets, and formation of non-farm enterprises, especially amongst females. It also provided more flexibility to families in terms of labor allocation decisions and reduced child labor, especially for boys. However, it had little impact on crop production.
  • Cunha (2014) studied a Mexican food assistance program aimed at promoting better nutrition, and found that in-kind food transfers did not lead to meaningful differential improvements in overall consumption and health outcomes as compared to the provision of cash transfers, as the cash was largely spent on nutritious food as well.
  • McEwen and Stewart (2014) study the effects of the Canadian child allowance program that started in 1945. They highlight that significant correlation between lower income and worse child outcomes (social, cognitive, behavioral, emotional) can be explained by factors usually associated with a lower income, such as lower educational attainment, less employment, and living in a risky neighbourhood. A household's income itself has a relatively small influence on child outcomes after considering these factors. This suggests that raising a poor household's income alone may not have a sizeable impact on children outcomes.
  • According to Akee et al. (2013), a cash transfer experiment in North Carolina (US) shows that, controlling for initial health conditions, household cash transfers lead to a larger increase in weight for children from the initially poorest households relative to those from richer households.
  • Studying the 1832 Cherokee Land Lottery, in which winners were randomly selected, Bleakley and Ferrie (2013) found that winners were on average richer in the long-run, but this was due to a movement of the winners in the middle of the wealth distribution to the upper tail of the wealth distribution. At the same time, winners in the lower tail of the wealth distribution were unaffected (no movement), hence exacerbating inequality.
  • Taylor et al (2013) examine the general equilibrium effects of a cash transfer for orphans and vulnerable children (CT-OVC) in Kenya. Using four administrative and private data sources, they simulate the estimates of income multipliers and highlight significant spillover effects of the CT-OVC transfers in local economies. Local income multipliers are significantly greater than 1 in nominal terms, even when capital and labor constraints limit the local supply response. They note most of the effects are among ineligible households, indicating that the program enables them to access more capital and labor to increase their production in response to local demand. They note variations in impacts across regions in the income multiplier, and highlight differences in capital, liquidity and labor market constraints.
  • DFID (2011) reports that there is substantial evidence that cash transfers can reduce inequality, boost movement out of poverty for working age populations, and lead to sizable gains in access to health and education indicators (with less marked success in the final outcomes of these two sectors). The authors report indicative and deterministic factors showing that cash transfers can improve household productivity, income generation, gender equality, empowerment of the poor, and local market development. They also report that there is little evidence of negative labor market effects and negative effects on fertility. While acknowledging the limited evidence on aggregate growth, the authors suggest that cash transfers can lead to long term growth through improvements in human capital.
  • Ardington, Case, Hosegood (2009) found that in South Africa, large cash transfers in the form of pension payments to the elderly led to increased employment amongst prime-aged adults through labor migration, as a pension increases household resources which can be used to support migrants until they become self-sufficient. The finding implies that pensioners are able to care for small children while prime-aged adults look for work.
  • A study by Imbens, Rubin, Sacerdote (2001) assessing lottery winners in Massachusetts in the 1980s finds that unearned income reduces labor earnings, with a marginal propensity to consume leisure of approximately 11 percent, and with larger effects for individuals between 55 and 65 years old. The savings rate for unearned income is about 16 percent for those who received half their income and increases with the proportion of the income received.

Conclusion

There is only a limited amount that studies on small-scale cash transfer interventions can tell us about UBI. However, one thing we can learn from these studies is that there is little empirical evidence to suggest the materialization of the harms or dangers usually associated with cash transfers. In other words, we don’t see entire populations quitting work or using the cash transfers on temptation goods. This possibly provides a reason for sustained interest in basic income research.

Based on our review of the literature, it would be useful for future research efforts to examine labor effects and community effects more closely. Most of the CCT and CT studies conduct sampling on the individual level, and it is hard to find studies which report on community effects and changes in interpersonal relationships. We would also like to see more post-intervention studies about what happens to recipients at the end of the disbursement periods, and in particular whether the changes in their behavior are sustained. We’re also looking forward to seeing more papers on the long-term impacts of cash transfers -- on the effects on distribution of wealth, and intergenerational effects in households, for example. We want to note our appreciation for the papers on the study in Kenya, which cover a whole gamut of effects--the 2018 paper examines spillover effects, which is both rare and important in this discourse.

Finally, we see a need for pilots to be carried out on a much larger scale, in order to get at the population-wide effects of a UBI. A large-scale pilot will be useful in helping to generate empirical macroeconomic analysis, as well as reveal new effects at the micro- and meso- economic levels. After all, a UBI is not just a research study, but an institution which is well worth our consideration. What would it look like to implement such an institution?
