Improving Housing Affordability

Download Paper Executive Summary

Housing affordability in the United States has become a major challenge for Americans and a key policy priority for US policymakers. In this paper, Benjamin Keys and Vincent Reina assess the drivers of the housing affordability challenge, concluding that inadequate supply, barriers to homeownership such as tight credit standards, and the lack of a meaningful housing safety net have made affordable housing increasingly out of reach for many Americans. The authors then propose specific policy solutions to expand supply, improve access to homeownership, and strengthen the housing safety net. 

Keys and Reina first lay out several facts about the decline in housing affordability in the United States. Since 1980, median inflation-adjusted rent has nearly doubled—from under $950 to $1,700 in 2023—while the share of affordable rental units has collapsed from more than half of the housing stock to just over 20 percent. The share of renters who are “rent burdened,” spending over 30 percent of their income on housing, has risen from 35 to 48 percent.

Second, homeownership has become increasingly out of reach. The ratio of median sales price to median income has increased from 2.4 in 1990 to 5 in 2023. With home prices elevated, first-time buyers are entering the market later and in smaller numbers. The median age of a first-time buyer has climbed from 29 in 1980 to 38 in 2024, and the share of all housing purchases made by first-time buyers fell from 50 percent in 2010 to 24 percent in 2024.

Keys and Reina identify four main drivers of the nation’s housing affordability crisis: 

Challenges in building housing. Local land-use and zoning restrictions have sharply limited housing supply. Lengthy permitting processes, uncertainty, and high fixed development costs further push up costs for builders, incentivizing the construction of high-priced, luxury units and leaving the low-cost segment undersupplied. 

Barriers to homeownership. Homeownership has become increasingly difficult due to tighter credit standards, high levels of student-loan debt, and disproportionately high denial rates for minority households. Lending standards to obtain high-LTV, fixed-rate, 30-year mortgages have increased since the global financial crisis: average FICO scores for newly originated purchase mortgages have increased from 705 in 2006 to 740 in 2022. 

A lack of a housing entitlement program. The United States has never had a housing safety net for renters or owners, and the existing assistance leaves many eligible recipients without support. For every one household that receives a housing choice voucher, as many as four other households are eligible. Public housing represents less than 2 percent of units, and the Low Income Housing Tax Credit produces only about 110,000 units annually, often at rents too high for the lowest-income families. 

Barriers to financing construction and repairs. Developers and owners both face barriers when trying to finance new development, which affects the supply of new units being built, and rehabilitation, affecting the ability of units to stay in the housing stock. Since 2015, tighter credit standards have constrained developers, landlords of small properties, and homeowners seeking to rehabilitate aging housing stock. 

In response to these challenges, Keys and Reina outline three key policy proposals to improve housing affordability: 

Make it easier to build. Policymakers at all levels can make it easier to build by accelerating production, reducing barriers, and incentivizing sensible density through zoning reforms, such as reducing minimum lot sizes and parking requirements, and allowing accessory dwelling units near transit. The federal government could further expand multifamily financing through a loan system similar to the current system in place for single-family lending. 

Address barriers to home ownership. The tax code can be reformed to reduce barriers to homeownership by converting the regressive mortgage interest deduction into a targeted first-time homebuyer credit while balancing demand-side incentives to avoid driving up prices. Policymakers could also explore taxes on imputed rent to encourage downsizing, make existing mortgages more assumable or portable, and expand tax-credit programs like the proposed Neighborhood Homes Tax Credit to support the development of affordable for-sale housing. 

Create a stronger housing safety net. Strengthening the housing safety net would ensure affordable shelter during income shocks by expanding proven tools like direct rental assistance and national emergency-rental support to promote greater housing stability.

Current Evidence on Household Financial Well-Being

Download Paper

Despite strong economic conditions, survey data reveal substantial economic worry and discontent among Americans. Pew survey data from 2024 indicated that “strengthening the economy” was Americans’ top policy priority, above “defending against terrorism,” “reducing crime,” and “dealing with immigration” (Pew 2024). A separate Pew survey from that same year found that only 53 percent of Americans believe that the “American Dream,” defined as the idea that anyone can achieve success in the United States through hard work and determination, is still possible (Borelli 2024).

Advancing broad economic prosperity requires an understanding of the economic well-being of American households, as well as potential contributors to widespread economic malaise. With that goal, this piece highlights current evidence on household financial well-being through six facts and accompanying figures. First, we document trends in earnings and income growth across the wage distribution as well as by educational attainment, gender, and geography. Second, we highlight trends in the costs of two salient household budget items: housing and healthcare.

1. Compared to half a century ago, inflation-adjusted wages have risen across the income distribution.

The typical worker in the United States earned more in recent years than at any point over the past half century, after adjusting for the rising cost of living.[1] Figure 1 shows that median hourly wages increased by 33 percent from 1973 to 2023 and that wages increased across each earnings decile over that time. To be sure, wage growth has not been uniform across time or across the wage distribution. The lowest earners (the bottom 10 percent), for instance, experienced a sharp decline in real wages from 1979 through 1997. In the subsequent period, from 1997 to 2023, however, real wages have risen 48 percent among the bottom decile of earners—compared to 33 percent for the median worker and 37 percent for the 80th percentile of earners. Thus, the overall story of the American worker is one of substantial wage growth over the past half century and particularly over the past 30 years.

[1] Throughout this paper, we adjust earnings and income data for the rising cost of living using the Personal Consumption Expenditures (PCE) price index. Researchers typically deflate such data using either the PCE or the CPI-U-RS, a version of the Consumer Price Index for all Urban Consumers (CPI-U) that incorporates improvements made to CPI calculation methods over time (BLS 2025). We prefer the PCE price index as it is a chain-type price index, meaning it incorporates consumers’ substitution behaviors as the relative prices of goods change (BLS 2011).

2. Over the past four decades, household income has risen across the income distribution, reflecting both rising earnings and a more generous tax-and-transfer system.

While fact 1 concerns long-term trends in individual worker wages, examining trends in household income helps to shed light on how total resources have changed, taking into account changes in household structure and the tax-and-transfer system. Figure 2 plots changes in household income, showing both market income and total income, by income quintile. “Market income” consists of wages, along with additional labor income (such as employers’ contributions for health insurance premiums), business income, and capital gains (CBO 2024). For all quintiles, both market income and household income increased between 1979 and 2019. For the lowest quintile of households, market income rose by 40 percent. Post-tax and transfer income of this group increased by 100 percent. As outlined by Kearney and Sullivan (2025), changes to the US tax-and-transfer system over this time, such as expansions to the Earned Income Tax Credit, have played a large role in raising the resources of low-income households.

3. Labor market outcomes have been marked by an increased return to education and a decline in inflation-adjusted wages for men without college degrees.

Despite rising wages across the income distribution and broad growth in household income, certain groups have fared better than others over the past five decades. Indeed, breaking apart wage data by gender and education highlights two key economic trends. First, there has been a consistent rise in the return to education from 1973 to 2024. Both men and women with a college degree or higher, especially those with advanced degrees, have experienced the strongest real wage growth: From 1973 to 2024, wages for men and women with advanced degrees have risen 38.4 and 32.9 percent respectively; wages for men and women with college degrees have risen 16.9 and 27.6 percent, respectively. Second, in contrast, men without college degrees have fared poorly in the labor market. Over this time, real wages declined 15.5 percent for men with high school degrees and 7.8 percent for men without high school degrees.

The twin trends of widening inequality in wages by education groups and the decline in earnings among men without college degrees are largely a product of developments in prior decades, including automation and globalization. Advances in technology that began in the 1980s sparked a polarization in the labor market that increased the returns to education and shifted workers without college degrees into low-wage jobs (Katz and Autor 1999). Men without college degrees saw wages stagnate in the first decade of the 2000s, as those who had been working manufacturing jobs that were eliminated due to rising global competition then moved into service-sector jobs (Autor et al. 2016). In the past decade, however, labor-market polarization has given way to general skill upgrading in the labor market, as Deming et al. (2024) describes, and real wages have risen across all education levels, including for men with less than a college degree.

4. Geographic income inequality has widened since 1980. 

The dynamics described above tie directly into differences in economic growth that have emerged across geographies over this time. Figure 4 shows that from 1980 to 2023, per-capita real income (excluding government transfers) for the top 1 percent of counties rose by 165 percent, compared to 84 percent for the median county.

This divergence across cities reflects the dynamics of both labor markets and housing markets. The increased concentration of “knowledge workers” in cities fostered further growth, creating what Enrico Moretti (2004; 2012) has called the “Great Divergence” between highly educated, high-income, high-growth cities that attracted these workers and the areas that did not. Furthermore, as David Autor (2020) detailed, over this period, cities experienced a decline of middle-paying production or clerical jobs that a worker without a college degree might have once found there. From 1980 to 2015, the “urban wage premium” for workers with a college degree or greater rose by 50 percent, driven by the rise of high-paying professional and managerial jobs in cities.

At the same time, inelastic housing supply in these “superstar” cities caused house prices to rise to the point that living in such cities has become unaffordable for many low-wage service-sector workers (Gyorko, Mayer, and Sinai 2013). These developments have cut off a key mechanism of regional income convergence and individual economic mobility—a mechanism of which America’s cities have historically served as a trademark (Glaeser et al. 2005; Glaeser 2011; Ganong and Shoag 2017).

5. Rising housing costs have strained the budgets of many low-income Americans, making renting more burdensome and homeownership increasingly unattainable.

To be sure, rising housing costs are a concern not only in large cities but across the country, as Keys and Reina (2025) detail. Rent is consuming a larger share of household budgets, rising home prices are making home buying unaffordable, and for recent homebuyers, high mortgage rates mean that mortgage payments consume a significantly higher share of monthly budgets than they did for prior cohorts.

Figure 5 shows that roughly half of US renters are now classified as rent-burdened, meaning they spend 30 percent or more of their income on housing (US Census Bureau 2024). This burden is the largest for low-income households. In 2022, 83 percent of renters with incomes below $30,000 spent at least 30 percent of their income on rent. The largest increases over time have been seen for middle-income renters: The share of households making between $45,000 and $75,000 who spent at least 30 percent of their income on rent has nearly doubled since 2001, reaching 45 percent in 2022 (Airgood-Obrycki 2024).

Likewise, high interest rates, tight lending standards, and constrained supply have made homeownership increasingly unaffordable for the typical American. Figure 6 shows the Federal Reserve Bank of Atlanta’s estimate of the income needed if annual homeownership costs are to equal no more than 30 percent of annual income and plots it against the actual median income. From 2008 to 2019, that “qualified income” matched the median annual income. But from 2020 through 2023, the qualified income has risen to 1.5 times the median annual income.

Finally, for homebuyers able to obtain a mortgage since the pandemic, housing costs take up a substantially higher share of income compared to costs for homebuyers pre-pandemic, as shown in figure 7 below. For a buyer who obtained a mortgage in 2016, those payments consumed on average 15 percent of income in the first year; for a buyer in 2024, first-year mortgage payments made up 26 percent.

6. Healthcare costs are outpacing inflation.

Housing is not the only household necessity that has become increasingly expensive. Healthcare costs in the United States have risen steadily over the past several decades. Americans face high and rising out-of-pocket costs, which more than doubled from $677 per person (inflation-adjusted) in 1970 to $1,425 in 2022, as shown in figure 8. Importantly, out-of-pocket expenditures do not include spending on health insurance premiums, which have also risen substantially. In 1999, an average worker contributed $1,564 in premiums for family health insurance (not including the employer’s contribution); by 2024, that cost had more than quadrupled to $6,393 (KFF 2024).

Research has found that healthcare costs are rising largely because prices—that is, the amount individuals pay for goods and services like pharmaceutical drugs, physician care, and hospital stays—have risen, as opposed to families consuming more healthcare and prices staying the same (Anderson et al. 2019). Figure 9 shows that while the overall consumer price index has risen 86 percent since 2000, the index for medical care has risen 121 percent.

While part of the rise in prices has been attributed to forces like hospital consolidation, high prices are also a result of valuable innovations that have led to new (and more expensive) drugs and treatments (Cooper et al. 2019). As Garthwaite and Starc (2023) lay out, high prices themselves serve as an incentive for firms to make costly investments in innovation, which increases access to new drugs and treatments in the future. In this way, reforms should focus on driving value in today’s healthcare system—by (for example) improving transparency and competition at several points in the pharmaceutical drug supply chain, rather than strictly by lowering prices.

Conclusion

Advancing widespread prosperity today requires a clear understanding of the current state, and historical evolution, of household economic well-being. Contrary to popular claims, American workers across the wage distribution are materially better off now than they were in 1979. Wage growth has exceeded the increased cost of living even for the bottom 10 percent of workers—indeed, the story of wage stagnation is largely one that ended in the mid-1990s. The rise in household income has been even greater due to the increased generosity of the tax-and-transfer system.

However, automation and globalization have widened the gap in wage growth between those with college degrees or greater, who have seen faster-than-average wage growth, and non-college workers, particularly men with high school degrees or less. These highly educated workers clustered in a small set of high-tech cities, and as housing supply failed to keep up with demand, such cities became too expensive for low-wage workers—driving a trend of widening geographic income inequality and cutting off mechanisms of economic mobility. Indeed, housing costs are increasingly straining renters’ and many homeowners’ budgets across the country. Along with housing, healthcare costs are a salient household expense that has outpaced overall price growth in recent decades.

Beyond the Myths: A Clearer Path to Poverty Alleviation in America

Download Paper Executive Summary

In “Beyond the Myths: A Clearer Path to Poverty Alleviation in America,” Melissa S. Kearney and James Sullivan reassess poverty trends and policy responses in the United States. They document that, contrary to common perceptions, poverty has declined substantially over the past four decades and that anti-poverty programs have played a central role in this progress.

The authors argue that framing poverty reduction as a matter of simply transferring cash overlooks the complex and multifaceted challenges faced by those living in poverty. Sustained progress requires investing in people’s capacity to succeed, with particular attention to four areas: developing skills, strengthening families, removing barriers to individual flourishing, and expanding upward mobility for children born into disadvantaged circumstances.

Kearney and Sullivan outline three key common misconceptions about poverty in the United States. 

Misconception 1: The US has made little progress at reducing poverty.
For many years, policymakers and pundits have claimed that poverty has not fallen. However, Kearney and Sullivan show that, when measured accurately, poverty has fallen dramatically since the 1980s—by roughly half according to income-based measures and by more than 80 percent using consumption-based measures. Broader indicators of material well-being, including housing quality and access to amenities, tell the same story: poverty has declined substantially over the past four decades.

Misconception 2: Anti-poverty programs are ineffective.
Anti-poverty programs have been central to poverty reduction over the past four decades. Comparisons of pre- and post-tax incomes of low-income households show that tax credits and in-kind transfers directly reduce the poverty rate by roughly two-thirds—from 17.4 percent before taxes and transfers in 2023 to 6.1 percent after them. Beyond their immediate impact, programs such as the Earned Income Tax Credit, SNAP, and Medicaid yield long-term benefits for children, improving health, educational attainment, and adult earnings, underscoring the importance of maintaining these safety nets alongside policies that promote long-term self-sufficiency.

Misconception 3: Just giving people cash will solve poverty.
The claim that America could eliminate poverty simply by giving people money conceives of this problem too narrowly as a financial one, when in reality the challenge runs much deeper. Research on guaranteed-income programs shows that unconditional payments rarely lead to greater economic independence or investments in education and skills, as persistent poverty reflects structural barriers that money alone cannot resolve. True poverty alleviation requires addressing underlying issues—such as education, health, family stability, and barriers to work—through long-term investments in people and families.

Guided by facts and evidence, Kearney and Sullivan propose an anti-poverty agenda for the country focused on making long-term investments in people and families. They propose four specific areas of investment.

An anti-poverty agenda: Alleviating poverty requires investing in people

  1. Advance skills and education. Expanding access to high quality education and training is one of the most reliable ways to reduce poverty and promote long-term economic security. Comprehensive student-support programs, flexible high schools for adults, and sector-based workforce training programs can help students obtain skills valued in the labor market.
  2. Strengthen families. Family structure is strongly correlated with child poverty and long-term outcomes. Investing in strong families requires a multi-pronged approach aimed at addressing the decline in marriage among non-college educated adults, expanding programs that help low-income couples establish healthy relationships, and reforming the tax-and-transfer system to eliminate marriage penalties.
  3. Address individualized barriers to stability: All too often, individuals and families who struggle to make ends meet face a complex web of barriers that prevent them from becoming economically stable. Addressing poverty often requires providing assistance that is customized to the unique set of challenges that each individual or family faces.
  4. Boost upward mobility for poor children. Investments in children’s nutrition, healthcare, housing stability, and early education have proven to yield long-term gains in health, educational attainment, and earnings. 

These reforms, the authors stress, should complement policies that promote and sustain strong economic growth and widespread opportunities for all.

Introduction: Advancing America’s Prosperity

Download Paper

The United States stands at a pivotal moment in economic policymaking.  The Trump administration has profoundly reshaped America’s approach to international economics, adopting a more confrontational stance on trade and retreating from long-standing multilateral agreements. In April 2025, the Trump administration announced tariffs on goods from every US trading partner, ranging from 11 to 50 percent, which were then reduced to 10 percent as countries negotiated bilateral trade agreements (White House 2025b). This bilateral, “deals-based” approach to trade negotiations further cements the end of an earlier era of engagement through multilateral institutions.  

In addition, Congress has passed sweeping legislation that makes significant changes across a range of domestic policy areas. The recently passed One Big Beautiful Bill (OBBB) extends expiring provisions in the 2017 Tax Cuts and Jobs Act (TCJA), introduces new tax cuts, reduces the generosity of Medicaid and SNAP, rolls back incentives for renewable-energy investments, eases financing requirements for low-income housing, bolsters national defense, and strengthens border security efforts, all while adding an estimated $3.4 trillion to the federal deficit over the next ten years (CBO 2025). Questions abound about the economic implications of the bill’s many provisions, including how the permanence of some TCJA provisions will affect business investment, how changes to Medicaid and SNAP will impact vulnerable populations, and how the increase in debt will drive up interest rates and affect the macroeconomy. 

Meanwhile, rising geopolitical tensions and rapid advances in artificial intelligence are redefining the landscape for US strategic competitiveness. China is taking steps to advance its economic capacity and to boost its military capabilities, and Russia’s continued invasion of Ukraine marks its clear ambitions of territorial expansion. The US faces these rising global tensions with eroded industrial capacity and a weaker recognition of the connection between commercial interests and the country’s national interests that came to define prior decades.  

All these developments have fueled a high degree of economic uncertainty about economic conditions, for both households and businesses. Measures of consumer sentiment remain well below levels in 2023 and 2024 (Economic Policy Uncertainty Index n.d. and University of Michigan 2025, respectively). These developments also raise urgent questions about how best to safeguard and advance America’s prosperity and bolster America’s strategic competitiveness. 

This 2025 Aspen Economic Strategy Group (AESG) policy volume takes up these questions. The six chapters in this book, organized into two sections, consider the implications of these developments and evidence-based approaches to moving forward in a way that bolsters American economic prosperity. 

Aligning High-Skilled Immigration Policy with National Strategy

Download Paper Executive Summary

The United States’ innovative edge depends on its ability to draw on the best talent from around the world. However, the laws that govern high-skilled immigration are outdated and misaligned with the needs of today’s economy. Only a small share of green cards, which provide immigrants permanent resident status in the United States, are allocated based on skills or employment. These eligibility pathways are constrained by rigid numerical caps,  causing long and growing backlogs. As a result, temporary visas (such as H-1Bs and J-1s) have become the de facto system for recruiting and retaining high-skilled workers in the US, even though these pathways are not designed to provide long-term employment or residency. Moreover, these temporary visas are also subject to restrictive caps and allocation mechanisms that undermine strategic selection.

In Aligning High-Skilled Immigration Policy with National Strategy, Jeremy Neufeld outlines the shortcomings of the current high-skill immigration system and offers policy reforms that would advance the United States’s ability to attract, select, and retain the world’s most promising workers.

Green-card caps and per-country limits restrict the flow of high-skilled talent.
Each year, the US issues about one million green cards, which offer lawful permanent resident status, but only 7 percent go to individuals selected on the basis of their skills or job offers. These limits—set more than three decades ago—are compounded by per-country caps that can produce decades-long wait times. To address these issues, Neufeld proposes that Congress increase the number of green cards available for high-skilled workers, particularly in critical emerging-technology fields.

Temporary visa programs create bottlenecks and reduce selectivity.
U.S. recruitment of high-skilled workers relies heavily on temporary nonimmigrant visas such as F-1 student visas and H-1B specialty occupation visas, which are limited in duration and tightly constrained by employment rules. This “funnel” system accepts far more recruits at the top, through universities and exchange programs, than there are available green cards at the bottom. To strengthen selection and efficiency, Neufeld recommends replacing the random H-1B lottery with a compensation-based allocation system that prioritizes the most qualified candidates. 

Rigid visa rules limit innovation and fail to prioritize merit.
Visa holders are often tied to specific employers and have stringent, work-related restrictions, significantly limiting the labor market mobility of the visa holder. This rigidity significantly restricts innovation and entrepreneurship, preventing immigrants from starting their own companies or commercializing research for fear of losing their visa, and in turn limiting innovation spillovers that would otherwise benefit the broader economy.

Neufeld proposes a points-based green-card system that awards visas based on characteristics associated with success, like education, SAT scores, salary, language proficiency, and job offers. Furthermore, he also recommends more proactive talent recruitment, as existed during the end of World War II. He suggests that talent scouts could experiment with identifying and recruiting to the United States winners of math and science olympiads, winners of scientific prizes, budding entrepreneurs, and top young scientists, in order to attract the highest potential immigrants.

 

Advancing America’s Prosperity

The United States stands at a pivotal moment in economic policymaking. Sweeping domestic legislation changes, rising geopolitical tensions, and rapid advances in artificial intelligence have fueled a high degree of uncertainty about economic conditions, for both households and businesses. These developments also raise urgent questions about how best to safeguard and advance America’s prosperity and bolster America’s strategic competitiveness. The Aspen Economic Strategy Group’s eighth annual policy volume focuses on the theme, Advancing America’s Prosperity. Together, the volume’s six papers, which will be published throughout the fall, address key questions about what US policymakers and business leaders should do to elevate US economic competitiveness, advance our national interests, and foster broad-based economic prosperity.

Key Takeaways from “After the Spike: Population, Progress, and the Case for People”

On July 9th, 2025, the Aspen Economic Strategy Group hosted economists Michael Geruso and Dean Spears for a conversation on their new book, After the Spike: Population, Progress, and the Case for People. In After the Spike, Geruso and Spears examine the decline in global birth rates and consider what a drop in the global population would mean. They make a data-focused case that depopulation threatens technological and social progress and examine how we could build a society that avoids such a future.

The program featured an opening presentation from Geruso on the data behind his and Spears’ argument. Geruso first broke down current projections for the global population, noting that the most likely future is that, after a final few decades of growth, the world’s population will face exponential decline. He continued, “Let’s imagine that the world as a whole converged to a birth rate that would feel very familiar to all of us in this room. A birth rate of 1.6, 1.6 kids for every two adults. That happens to be the birth rate of the United States today. What that sort of future would mean is rapid global depopulation.” Geruso asserts that this rapid drop —“a world population that falls by two-thirds every century”— is an undesirable future for humanity. Because humanity’s progress results from the innovations, discoveries, and technologies that people create, Geruso concludes, “A populous world is a more prosperous world with better lives on average for everybody.” 

The event also featured a panel discussion with Geruso, Spears, and AESG Director Melissa S. Kearney. The panel touched on topics including overpopulation, environmentalism, and solutions that might make individuals more likely to choose to have children.

Kearney kicked off the discussion with a reference to Paul Ehrlich’s book, The Population Bomb, and asked the authors to explain their focus on the risks of depopulation, given that concern over population growth, and in particular its impact on the environment, dominates conventional wisdom. “That story missed that humanity, even then, wasn’t on a path to population growth, generation after generation forever, without any sort of end,” Spears remarked. “Falling birth rates have been around for a long time. Not only is this not just a US phenomenon, but it’s a worldwide phenomenon. It’s also a phenomenon that’s been spreading over time for a long time.”

Furthermore, on the question of the relationship between population and climate change, Spears remarked, “The question we need to ask now is whether a smaller population is going to be the solution to [environmental] challenges.” He cited China’s air pollution problem as an example. “Even though there were more people, the environmental damage was lessened because people did something different: new regulation, new enforcement, turning off coal plants,” Spears said. “People making decisions resulted in less pollution. Every time we’ve made progress against our environmental challenges before, that’s been how we’ve done it.”

On how to think of population decline in the context of rapid technological advancements, Geruso argued, “Global depopulation is not going to relieve us of our duties to confront climate change because global depopulation isn’t going to start happening for several decades after we should be making progress on climate this decade in the next. And in the same way, it’s not going to interact with AI in the way that people sometimes think because what’s going to happen with AI is going to be very fast—the next year, the next decade. The population will still be growing at that time.”

The panelists also highlighted that achieving population stabilization requires individuals to want to choose to have children, and that means that we need to make it easier for people to make that choice. Kearney remarked “the book makes it clear that the answer to this is not to restrict women’s choices and opportunities. Getting society, not just men, but society, to share in more of the care burden has to be part of the response.” Geruso emphasized, “Does addressing [population decline] mean backsliding on gender equality?  Very clearly the answer is no.” He continued, “We don’t think children are women’s responsibility. We think that we all benefit from getting to live in a big world and that means we should all share in the responsibility of creating the next generation.”

Supporting Families, Rewarding Work: A Proposal to Reform and Enhance the EITC and the CTC

The federal Earned Income Tax Credit (EITC) and the Child Tax Credit (CTC) are important sources of income support to workers with low earnings and to low-income families with children. In this policy brief, the authors propose incremental reforms to both credits that would streamline the dual goals of rewarding work and supporting children, while also expanding income assistance for low-income families with children.

This proposal reorients the EITC around its primary purpose of subsidizing wages of low earners, while using the CTC as the primary tool to support families with children. The authors propose a simplified EITC schedule with higher income thresholds and credit amounts for married tax filers, where thresholds and credit amounts vary if filing units claim children, but not by the number of children claimed. This structure maintains the desirable work incentives of the EITC while separating out the delivery of income assistance targeted at children. 

This streamlined EITC is combined with the enhanced CTC proposed by Edelberg and Kearney (2023). This enhanced CTC features an increased full credit amount, partial refundability for those with zero earnings, a steep phase-in, and a gradual phase-out range at high levels of income. It would reduce child poverty, maintain tax incentives to work for low earners, and discipline the costs of the program by beginning the phase-out of the credit at a lower household-income threshold than the one set by current law.

Current (1 Child) vs Proposed EITC Schedule

Current and Proposed CTC Schedule

Under this plan, families with children making under $100,000 will see an average increase in annual income of 11.5 percent. Those making under $40,000 annually will see the greatest percentage gains. Under our proposal, child poverty (as measured by the supplemental poverty measure) will fall by 3 percentage points; our proposal is expected to cost $55.6 billion annually relative to the current EITC and CTC.

AESG Insights: The Economics of Falling Birth Rates

THE ECONOMICS OF DECLINING US FERTILITY
Recent proposals such as “baby bonuses” and expansions to the Child Tax Credit have cast increased attention on the issue of declining birth rates in the US. The AESG and its director Melissa S. Kearney have repeatedly highlighted the significant social and economic consequences of the country’s falling birth rate and considered what it will take to reverse current trends.

CAUSES AND CONSEQUENCES
Fertility rates in the US have fallen from a recent peak of 69.5 births per 1,000 women 15-44 years old in 2007 to 54.4 in 2023. In their 2022 AESG paper, The Causes and Consequences of Declining US Fertility, Melissa Kearney and Phillip Levine examined the key forces driving this trend, along with its economic implications.

Absent a significant change in immigration patterns, slower birth rates will lead to slower population growth, and eventually a decline in the working-age population. This shift brings important fiscal implications, particularly for funding entitlement programs including Social Security and Medicare. Because such programs are funded through payroll taxes on current workers, a shrinking ratio of workers per retiree will exacerbate strains on entitlement funding. This ratio has already fallen from 4.0 workers per beneficiary in 1964 to 2.7 today. If fertility rates remain near current levels, funding gaps will grow wider, and workers could see tax increases of 20% to maintain the program’s solvency.

More broadly, a decline in the working-age population can hamper economic growth through slower rates of innovation and business dynamism. With a constant share of the workforce dedicated to research and development, for instance, a smaller workforce produces fewer innovations that in turn can increase all workers’ productivity and raise living standards.

Kearney and Levine found “no evidence that any particular policy, economic factor, or social trend has changed in recent years in a way that could explain the steady, widespread decline in US birth rates.” Instead, they attribute this decline to shifting priorities across recent cohorts of young adults.

They draw on these findings in their evaluation of the effects of “pro-natalist” policies, which incentivize childbearing through the provision of additional income to families based on their number of children. Kearney and Levine looked at evidence from countries that have implemented policies such as “baby bonuses” and concluded that such efforts tend to produce only modest increases in birth rates. Further, they wrote that it is unlikely that incremental policy reforms of this type would lead to a large enough increase in US birth rates that could return the total fertility rate to replacement levels in the near future.

However, more recent research by Kearney and co-author Lisa Dettling does find a strong link between the large expansion of homeownership in the middle of the 20th century and the size of the baby boom at that time. Specifically, Kearney and Dettling find that the adoption of the low down payment, long-term, and fixed-rate mortgage in the US (standardized by the FHA and the VA), which made homeownership more accessible to young families, led to 3 million additional births from 1935-1957, roughly 10 percent of the excess births in the baby boom. They find evidence across countries that the availability of low-down payment mortgages “set the stage” for the higher birth rates. This evidence suggests that while incremental policies, like small baby bonuses or a higher child tax credit, will not change the country’s fertility trajectory, policies that produce a meaningful impact exist. However, in order for such policies to be effective, they will either be significantly more expensive than current proposals or involve large-scale change.

As Kearney wrote in an essay for The Dispatch, “we should not blithely declare that falling birth rates are of no real consequence, or even something to be celebrated. An increasingly aging and childless culture poses problems for individuals, families, and nations.” She argued that, if the decline in birth rates is the result of conscious choices made by new generations of Americans, there are still steps policymakers can take to mitigate the economic fallout. Comprehensive immigration reform and policies meant to promote innovation and productivity are two ways policymakers can respond to the economic realities brought about by below replacement-level fertility.

However, Kearney also considers an alternative scenario about declining fertility: that there are other constraints leading Americans to choose not to have children. If falling birth rates are a reflection of social constraints, such as family unfriendly policies, lack of egalitarian norms in marriage, and unequal divisions of household labor, then policymakers should consider meaningful efforts to address the realities that Americans are reacting to.

In light of renewed recent attention, Kearney appeared on CBS Mornings this week to discuss these trends. “On an aggregate level, the decline in birth rates in the US does pose challenges for us as an economy and society,” she said. “I think the conversation we should be having is are there things we could be doing as a society to make parenthood feel more accessible to people who would want to have children if they weren’t forced to essentially bear the responsibilities on their own.”
