HOW RESEARCH AFFECTS POLICY

Results from Brazil

How can evidence inform the decisions of policymakers? What value do policymakers ascribe to academic research? In January, we highlighted Yale's Evidence in Practice project, which emphasizes the divergence between policymakers' needs and researchers' goals. Other work describes the complexity of getting evidence into policy. A new study by JONAS HJORT, DIANA MOREIRA, GAUTAM RAO, and JUAN FRANCISCO SANTINI surprises because of the simplicity of its results—policymakers in Brazilian cities and towns are willing to pay for evidence, and willing to implement (a low-cost, letter-mailing) evidence-based policy. The lack of uptake may stem more from a lack of information than a lack of interest: "Our findings make clear that it is not the case, for example, that counterfactual policies' effectiveness is widely known 'on the ground,' nor that political leaders are uninterested in, unconvinced by, or unable to act on new research information."

From the abstract:

"In one experiment, we find that mayors and other municipal officials are willing to pay to learn the results of impact evaluations, and update their beliefs when informed of the findings. They value larger-sample studies more, while not distinguishing on average between studies conducted in rich and poor countries. In a second experiment, we find that informing mayors about research on a simple and effective policy (reminder letters for taxpayers) increases the probability that their municipality implements the policy by 10 percentage points. In sum, we provide direct evidence that providing research information to political leaders can lead to policy change. Information frictions may thus help explain failures to adopt effective policies."

  • New work from Larry Orr et al addresses the question of how to take evidence from one place (or several places) and make it useful to another. "[We provide] the first empirical evidence of the ability to use multisite evaluations to predict impacts in individual localities—i.e., the ability of 'evidence‐based policy' to improve local policy." Link.
  • Cited within the Hjort et al paper is research from Eva Vivalt and Aidan Coville on how policymakers update their prior beliefs when presented with new evidence. "We find evidence of 'variance neglect,' a bias similar to extension neglect in which confidence intervals are ignored. We also find evidence of asymmetric updating on good news relative to one’s prior beliefs. Together, these results mean that policymakers might be biased towards those interventions with a greater dispersion of results." Link.

Debating growth and the Green New Deal

In past newsletters, we have highlighted research and policy proposals relating to the Green New Deal and the literature surrounding "degrowth"—the idea that the growth imperative is at odds with human flourishing. In a recent exchange, economist Robert Pollin debates sociologists Juliet Schor and Andrew Jorgenson on the relative merits of "decoupling" and "degrowth." The former asserts that "economies can continue to grow while advancing a viable climate-stabilization project, as long as the growth process is decoupled from fossil-fuel consumption." The latter holds that public discussions over combating climate change must turn "from growthcentricity to needs- and people-centered policies."

The authors share a commitment to increased public investment, and both sides emphasize the distributional consequences of decarbonization. Their debate turns on, and illuminates larger conversations regarding the discursive frameworks and metrics we use to understand economic life. Schor and Jorgenson see reducing GDP in the global north as one element of a program to radically restructure the principles of society; Pollin understands these efforts to muddy the mandate for immediate climate action.

From Pollin:

"Let’s assume that global GDP contracts by 10 percent over the next two decades, following a degrowth scenario. That would entail a reduction of global GDP four times larger than what we experienced over the 2007–2009 financial crisis and Great Recession. In terms of CO2 emissions, the net effect of this 10 percent GDP contraction, considered on its own, would be to push emissions down by precisely 10 percent—that is, from 32 billion tons to 29 billion. So, the global economy would still not come close to bringing emissions down to 20 billion tons by 2040.

The overwhelming factor pushing emissions down will not be a contraction of overall GDP but massive growth in energy efficiency and clean renewable energy investments (which, for accounting purposes, will contribute toward increasing GDP) along with similarly dramatic cuts in fossil-fuel production and consumption (which will register as reducing GDP). In my view, addressing these matters in terms of their specifics is much more constructive than presenting broad generalities about the nature of economic growth, positive or negative."

Link to Pollin's initial paper, link to Schor and Jorgenson.

  • Pollin elaborates on this point in his follow-up statement with a case study of Japan: "Despite the fact that Japan has been close to a no-growth economy for twenty years, its CO2 emissions remain among the highest in the world, at 9.5 tons per capita." Link. Another recent article reviews and recaps the decoupling vs. degrowth exchanges. Link.
  • Schor and Jorgenson’s follow-up challenges Pollin's conviction that decoupling is either possible or efficient: "After decades of promises from advocates of green growth that absolute decoupling will happen, the record is dismal. The simple point about growth is therefore that it makes the nearly impossibly high mountain that we need to climb even steeper. Why rule out an important source of emissions reductions before we’ve even started?" Link.
  • Another iteration of the debate in a compilation of INET papers: Schröder et al argue that "if past performance is relevant for future outcomes, our results should put to bed the possibility of 'green growth.'" Michael Grubb takes a different tack: "Before declaring that history has set limits on what is possible, we need to be extremely careful. The future has already started, though its beginnings may be modest." Link.

MOBILE COGNITION

The political history of economic statistics

Debates over the relevance of indicators like GDP for assessing the health of domestic economies are persistent and growing. Critics of such measures point to the failures of such measures to holistically capture societal wellbeing, and argue in favor of alternative metrics and the disaggregation of GDP data. These debates reflect the politics behind the economic knowledge that shapes popular understanding and policy debates alike.

In his 2001 book Statistics and the German State, historian Adam Tooze examined the history of statistical knowledge production in Germany, covering the period from the turn-of-the-century to the end of the Nazi regime, "driven by the desire to understand how this peculiar structure of economic knowledge came into existence… and the relationship between efforts to govern the economy and efforts to make the economy intelligible through systematic quantification."

From the book's conclusion:

"We need to broaden our analysis of the forces bearing on the development of modern economic knowledge. This book has sought to portray the construction of a modern system of economic statistics as a complex and contested process of social engineering. This certainly involved the mobilization of economists and policy-makers, but it also required the creation of a substantial technical infrastructure. The processing of data depended on the concerted mobilization of thousands of staff. In this sense the history of modern economic knowledge should be seen as an integral part of the history of the modern state apparatus and more generally of modern bureaucratic organizations… The development of new forms of economic knowledge can therefore be understood as part of the emergence of modern economic government and as a sensitive indicator of the relationship between state and civil society."

MECHANICAL SHADOWS

On central bank independence and the rise of shadow money

Debates over the political impacts of Central Bank Independence (CBI) reached their peak in the late 90s and early 2000s, due to rising inequality and the volatility of financial markets. Initiated with the 1977 Federal Reserve Act and Paul Volcker’s subsequent term as chairman of the Fed, CBI was, and remains, a means of isolating the more "mechanical" field of monetary policy from the fleeting interests of politicians. In order to preserve stability and credibility, independent central banks have made inflation targeting the center point of their agenda. Critics of CBI have argued that the distinction between economic science and political incentives are not as clear as they might seem; low levels of inflation may benefit creditors and investors, but they harm those whose income entirely depends on rising wages. While monetary policy has distributional and political consequences, its decision makers are insulated from public accountability.

Expanding the literature on the politics of CBI, BENJAMIN BRAUN and DANIELA GABOR examine its financial consequences. In a recently published paper, they argue that the anti-inflationary policies of central banks have catalyzed dependence on shadow money and shadow banking, key components of a broader trend towards financialization:

"In the late 1990s, the US Federal Reserve was confronted with a peculiar predicament. While the world was celebrating central bank independence as a mark of 'scientific' economic governance after the populist era of monetizing government bonds, the US Federal Reserve worried about projections that the US government would pay down all its debt by 2012. A world without US government debt, they worried, was a world filled with monetary dangers. Market participants would not have a safe, liquid asset to turn to in times of distress.

Rather than seeking to limit shadow money supply, the Fed actively encouraged its expansion, seeking market solutions to political problems. It lobbied Congress to ensure that holders of shadow money backed by private (securitized) collateral had the same legal rights to collateral as those holding shadow money issued against US government debt. The Fed also changed its lending practices, allowing banks to issue shadow money backed by private collateral to borrow from the Fed. These concrete steps contrast starkly with the picture of central banks watching passively from the margins, as financial institutions find new ways to monetize credit and circumvent rules."

GREEN PLAN(K)

Growing the Green New Deal in the US and Europe

Jay Inslee, the governor of Washington State and Democratic presidential candidate, has made climate policy the center of his longer-than-long-shot campaign. On May 3rd, he released 8 pages of goals, and on May 16th, he released the 35-page, 28-policy “Evergreen Economy Plan,” with several more similarly lengthy reports on the way. David Roberts, an energy commentator at Vox, had a representative reaction to Inslee’s policies: “Inslee’s campaign is systematically translating the Green New Deal’s lofty goals — to decarbonize the economy sector by sector, in a way that creates high-quality jobs and protects frontline communities — into policy proposals.”

The report includes policies on infrastructure, manufacturing, R&D, and policies for energy workers, including a “GI Bill” and 8 million new jobs over the next 10 years. But beyond its extremely detailed recommendations, a key point of interest is seeing how the GND’s idealistic goals are cashed out. The introduction emphasizes a restorative approach:

“Inherent throughout ... is the urgent need to support frontline, low-income, and Indigenous communities, and communities of color. These communities are being impacted first and worst by the accelerating damages of climate change, and have endured a legacy of air, water, toxics and climate pollution, along with a deficit of public investment and support. Through an assertive agenda of reinvestment that is guided by strong local input, Governor Inslee’s plan seizes the opportunity to build a clean energy economy that provides inclusive prosperity — upon a foundation of economic, environmental, racial and social justice.”

Link to the report.

  • Leah Stokes, a climate and energy policy expert, contextualizes the expense on Twitter: “Spending $300 bn annually on climate is about 10% of the federal budget. Warren’s plan aggressively targets climate action by the military, which is about 20% of the federal budget. Hence, Inslee’s plan is about half the size of military spending. That’s BIG.” Link to the thread. - -
  • Noah Smith also takes up the cost question: "It’s probably less than 20 percent of what Ocasio-Cortez’s plan would cost, and only a quarter of the total would be paid by the government, so new budget deficits or taxes would be relatively modest. And because Inslee’s plan is more narrowly focused on value-generating investments like infrastructure rather than new entitlement spending, a higher percentage of the cost would be recouped down the road." Link.

CONTINGENT REFORM

The history and theory behind the Earned Income Tax Credit

The Earned Income Tax Credit (EITC) is the country's largest anti-poverty program. In 2018, over 20 million filers received $63 billion in EITC refunds. Because of its bipartisan popularity and its secure position in the tax code, with no distinct administrative unit managing its payouts, it is also at the center of several substantial anti-poverty programs recently floated in the House and Senate. These proposals variously expand and modify the EITC, often in concert with the Child Tax Credit, in order to offer a more robust benefit.

A look into the history of the EITC reveals that, at its formation, the credit was an unlikely candidate for a major anti-poverty vehicle. In a CONGRESSIONAL RESEARCH SERVICE paper, MARGOT KRANDLE HOLLICK lays out its legislative history, showing that its 1972 introduction by Senator Russell Long was an intervention against proposed guaranteed income programs, and that "the bill had originally included a provision that would have required states to reduce cash welfare by an amount equal to the aggregate EITC benefits received by their residents." From the paper:

"The origins of the EITC can be found in the debate in the late 1960s and 1970s over how to reform welfare—known at the time as Aid to Families with Dependent Children (AFDC). Some policymakers were interested in alternatives to cash welfare for the poor. Some welfare reform proposals relied on the 'negative income tax' (NIT) concept. The NIT proposals would have provided a guaranteed income to families who had no earnings (the 'income guarantee' that was part of these proposals). For families with earnings, the NIT would have been gradually reduced as earnings increased. Influenced by the idea of a NIT, President Nixon proposed in 1971 the 'family assistance plan' (FAP) that 'would have helped working-poor families with children by means of a federal minimum cash guarantee.'

Senator Russell Long, then chairman of the Senate Finance Committee, did not support FAP because it provided 'its largest benefits to those without earnings' and would, in his opinion, discourage people from working. Instead, Senator Long proposed a 'work bonus' plan that would supplement the wages of poor workers. Senator Long stated that his proposed 'work bonus plan' was 'a dignified way' to help poor Americans 'whereby the more he [or she] works the more he [or she] gets.'"

Link to that paper.

TANGLED PATHS

First steps to mapping the non-Title-IV education landscape

Title IV of the Higher Education Act of 1965 permits certain postsecondary institutions to be eligible for federal financial aid funds. A wide variety of programs are Title IV eligible: public, private, for-profit, vocational. Yet there are also a vast number of non-Title-IV (NT4) programs, offering credentials, certifications, and various forms of training—and neither the Department of Education, nor any other body, collects unified data on all these programs. How many students attend them? What subjects are they learning? What are their outcomes?

There's only been one recent paper that's made a serious attempt to understand the scale of NT4 programs. In a 2012 working paper, Stephanie Cellini and Claudia Goldin calculated that NT4 institutions educate 27% of students enrolled in for-profit institutions each year (670,000 enrollments).

A 2017 paper by Jessie Brown and Martin Kurzweil for the American Academy of Arts and Sciences attempts to map the alternative postsecondary landscape, including "certificate programs; work-based training; skills-based short courses; MOOCs; and competency-based education programs." That paper finds that these programs are growing:

“While each of these alternatives has roots that reach back decades if not longer, for a number of reasons, alternatives have increased in size, diversity, and importance in recent years, and are likely to continue to grow. Though the length and cost of alternative programs vary, most last for less than two years and cost significantly less than a four-year degree, the cost of which continues to rise rapidly… A characteristic feature of all the programs discussed is their flexibility to align directly with specific employer needs and competencies in skill-based fields. Despite these reasons for their appeal and likely growth, evidence of the efficacy and value of these alternatives—for students and taxpayers—is still thin.”

As the debate over the skills gap continues and the cost of college soars, the obscurity in which these programs operate becomes increasingly untenable. Link to that paper.

These agencies successfully used coercion and incentives on higher education institutions to develop more standardized admissions, instruction, and accreditation criteria to counter the lack of any existing academic standards."

PREMATURE PROGRESS

New patterns in deindustrialization

As economies across Europe and in the United States have become more knowledge-based, urban-centered, and tech-driven, people in manufacturing reliant regions have seen declining life expectancies, stagnating real incomes, and minimal job growth.

In recent years, social scientists have been grappling with the interconnected political, economic, and social effects of deindustrialization. But this literature is almost entirely confined to Europe and the U.S. In a new paper, DAVID KUNST broadens the scope of this research using a novel dataset on manufacturing employment by occupation in developing countries. He studies the labor market effects of 'premature deindustrialization,' finding a general decline in the hiring capacity of manufacturing sectors and a genuine risk from automation in emerging markets. The study comes to four conclusions:

"First, it is mostly unskilled jobs that have disappeared, and also the wage premium of workers with little formal education in manufacturing relative to other industries has declined. Second, the disappearing jobs have been among the most formal both relative to other industries, and to the manufacturing average. Third, premature deindustrialization has been driven by occupations which are intensive in tasks that are vulnerable to an increasing adoption of ICT. Fourth, the phenomenon pertains most clearly to middle income countries, as low income countries have been spared from premature job losses.

250 years after the beginning of the Industrial Revolution, it appears that manufacturing is losing its ability to employ unskilled workers more productively than other industries. Developing countries, abundant in unskilled labor, lose their comparative advantage in producing an increasing range of manufactured goods. Hence, future growth in developing countries may have to rely more on improvements in 'fundamentals' such as education and governance, and policy makers need to focus on a broader range of sectoral policies than in the past."

Link to the full paper.

  • The notion of 'premature deindustrialization' was developed by Dani Rodrik in 2015. In that paper, Rodrik argued that "countries are running out of industrialization opportunities sooner and at much lower levels of income compared to the experience of early industrializers" and suggested that "early deindustrialization could well remove the main channel through which rapid growth has taken place in the past." Link.
  • In a 2017 report, Carol Graham, Sergio Pinto, and John Juneau II map the "geography of desperation" in the United States: "In general, minorities scored worse on all of the variables in states where there are proportionately fewer minorities, such as Washington State and Kansas. These include Maine, Wisconsin, North Dakota, and Florida. Poor whites, meanwhile, tended to score lower across the board in the Appalachian states, and then poorly in many of the Midwestern and Western heartland states." Link. Two more reports from Brookings offer suggestions for place-based policies in the U.S. to counter these effects. Link, link.
  • David Clingingsmith and Jeffrey G. Williamson study the causes behind Indian deindustrialization from 1750-1860. Unlike literature which attributes the decline to growing competition in textile production from Britain, the authors find that the dissolution of Mughal hegemony and deteriorating climate conditions better account for the shift.

RESERVE GUARDS

Labor and discipline in the economy

As inequality has grown in salience as a political issue and object of research over the past decade, increasing numbers of social scientists are mapping the distribution of power and access throughout society. This new attention joins longstanding work that maintains, among other things, that free economic relations are accompanied by unequal property relations, involuntary employment, and an institutional framework to assure against incomplete contracts.

In a 2004 paper, Samuel Bowles and Arjun Jayadev argue that these dynamics are actively reproduced by guard labor: a section of the labor force whose primary function is to discipline other workers. Bowles and Jayadev find that all governments allocate a significant portion of their labor force towards these ends. Moreover, they find a strong correlation between the proportion of the labor force devoted to guard labor and domestic levels of economic inequality:

"The differences in the extent of guard labor among countries are substantial, ranging from a tenth of the labor force in Switzerland to over a fifth in the U.K and the U.S. Broadly, three groups are evident. Social Democratic countries which display low levels of guard labor, English-Speaking countries which display high levels of guard labor (with substantial supervision), and Southern European economies which exhibit unusually high unemployment rates and thus, large amounts of guard labor.

The composition of guard labor differs substantially among the nations, especially in the proportions of the two largest components: supervision and unemployment. The top four in guard labor—Spain, the U.K., the U.S. and Greece—for example, devote about a fifth of their labor force to supervision and unemployment combined. But the U.S. is distinctive, with less than half the amount of unemployment as either Spain or Greece and 50 percent more supervisory labor. A comparison between the English speaking countries suggests a similar story. The U.S displays between 90 and 50 percent more supervisory labor than Canada, Australia and New Zealand, but about 50 percent less unemployment than these countries."

Link to the paper, link to a 2014 Times op-ed by Bowles and Jayadev.

  • Drawing a comparison between unregulated American labor markets in the Gilded Age and those of the present, Suresh Naidu and Noam Yuchtman find that "the unregulated labour market generated militant and coercive labour movements and employer organizations, and led to increased allocation of resources toward the domestic policing and military capacities of the US government."

MODELED WISDOM

Modeling policy levers for housing affordability in urban centers

In nearly every major urban center, housing affordability is in crisis. Since the 1960s, median home value has risen by 112% across the country, while median owner incomes rose just 50%. For renters, especially since 2008, the problem is increasingly acute:nearly half of renters (over 20 million people) pay over 30% of their income on rent.

In New York City, nearly two-thirds of all residents are renters (half of whom are rent-burdened), and the politics of housing policy remain correspondingly fraught. In a recent paper, researchers JACK FAVILUKIS, PIERRE MABILLE, and STIJN VAN NIEUWERBURGH at Columbia Business School develop a dynamic stochastic spatial equilibrium model to quantify the welfare implications of various policy tools. Calibrating the model to New York City, the authors examine the interactions between funding and affordability policies to chart a possible path forward. From the paper:

"Policy makers are under increasing pressure to improve affordability. They employ four broad categories of policy tools: rent control (RC), zoning policies, housing vouchers, and tax credits for developers. Each policy affects the quantity and price of owned and rented housing and its spatial distribution. It affects incentives to work, wages, commuting patterns, and ultimately output. Each policy affects wealth inequality in the city and in each of its neighborhoods.

While there is much work, both empirical and theoretical, on housing affordability, what is missing is a general equilibrium model that quantifies the impact of such policies on prices and quantities, on the spatial distribution of households, on income inequality within and across neighborhoods, and ultimately on individual and city-wide welfare. Consistent with conventional wisdom, increasing the housing stock in the urban core by relaxing zoning regulations is welfare improving. Contrary to conventional wisdom, increasing the generosity of the rent control or housing voucher systems is welfare increasing."
