Regional parochialism and the production of knowledge in universities

"Scholarly understanding of how universities transform money and intellect into knowledge remains limited. At present we have only rudimentary measures of knowledge production's inputs: tuition and fees, government subsidies, philanthropic gifts, and the academic credentials of students and faculty. Output measures are equally coarse: counts of degrees conferred; dissertations, articles and books completed; patents secured; dollars returned on particular inventions. As for the black box of knowledge production in between: very little."

From the introduction to a new book on American social science research that aims to uncover the institutional pathways that produce (and favor) certain areas of research.

It continues:

"The rise of 'global' discourse in the US academy has coevolved with fundamental changes in academic patronage, university prestige systems, and the international political economy. America's great research institutions are now only partly servants of the US nation-state. This fact has very large implications for those who make their careers producing scholarly knowledge."

Link to the introduction.

  • A short interview with co-authors Mitchell L. Stevens and Cynthia Miller-Idris. "Sociology department chairs said frankly that they deliberately steer graduate students away from international study because such projects on non-U.S. topics are less likely to have purchase on the tenure-line job market.… The tenure process is largely mediated by disciplines, and because those disciplines prioritize their own theoretical abstractions, contextual knowledge loses out." Link.
  • A paper examines previous attempts to map the parochialism of a discipline, finding that “conventional measures based on nation-state affiliation capture only part of the spatial structures of inequality.” Employed therein: novel visualizations and mapping the social network structures of authorship and citation.

On the effects of DACA

Last week we linked to a paper that outlines the effects of DACA status on educational attainment and productivity:

"High school graduation rates increased by 15 percent while teenage births declined by 45 percent.… College attendance increased by 25 percent among women, suggesting that DACA raised aspirations for education above and beyond qualifying for legal status."

Given reader interest in that paper, we've compiled an overview, inspired by current events, of DACA-related studies across a range of domains.

  • On the economic effects of legal status for DREAMers, including the modeled impact of the DREAM Act: “We estimate DACA increased GDP by almost 0.02% (about $3.5 billion), or $7,454 per legalized worker. Passing the DREAM Act would increase GDP by around 0.08% (or $15.2 billion), which amounts to an average of $15,371 for each legalized worker.” Link.
  • The Cato Institute estimates the fiscal impact of the elimination of DACA, inclusive of projected productivity declines and enforcement costs: “The United States economy would be poorer by more than a quarter of a trillion dollars.” Link.
  • A study finds DACA moved 50 to 75 thousand unauthorized immigrants into the labor force while increasing incomes for immigrants at the bottom of the income distribution. Using these estimates, the author contends that the (now defunct) DAPA, which targeted unauthorized parents of US citizens and LPRs for legalization, would move over 250 thousand unauthorized individuals into employment. Link. Another finds a 38% reduction in the likelihood of poverty for DACA-eligible immigrants. Link.
  • As a complement to the above linked paper on education investment, more fine-grained results on education outcomes for DACA recipients: “the effect of DACA on educational investments depends on how easily colleges accommodate working students.” Link.
  • On the mental health outcomes of children of DACA recipients. Link. On the health outcomes for DACA recipients versus their unqualified DREAMer counterparts. Link. On Medicaid use in mixed-status families, and the effects of deportation risk thereon. Link.
  • Again from Cato, a report on the IRCA (alias "Reagan amnesty") reviews several studies of the economic effects of that 1986 law, which paired legalization for close to three million unauthorized immigrants with increased border security and employer verification. Alongside specific takeaways regarding wages and tax revenues for/from the population that gained legal status (increases in both), a larger claim emerges: legalization programs are most sensible "within the context of comprehensive immigration reform." Link. For more on the Reagan Amnesty and its legacy, see this report from the DHS and this post from the Migration Policy Institute.
  • Vox’s Dara Lind, one of the few reliably accurate mainstream reporters on immigration law and policy, gives an overview of the DREAMer generation: “It’s the combination of settledness and the difficulty of getting legal that make DREAMers generationally unique in the history of US immigration policy.” Link. An idea discussed in that post—that increased border enforcement paradoxically kept migrants in the U.S.—is given depth by Princeton sociologist Douglas Massey here and here. For more on the relationship between immigration law, increased enforcement, and the growth of the unauthorized population, see this paper, this book, and this article.

Considerations on funding UBI in Britain

The RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce) published a discussion paper on UBI. ANTHONY PAINTER outlines some key points here, including some thoughts on funding:

“To fund the ‘Universal Basic Opportunity Fund’ (UBOF), the Government would finance an endowment to cover the fund for 14 years from a public debt issue (at current low interest rates). This endowment would be invested to both fund asset growth and public benefit. The fund could be invested in housing, transport, energy and digital infrastructure and invested for high growth in global assets such as equity and real estate. This seems radical but actually, similar mechanisms have been established in Norway, Singapore and Alaska. In the latter case, Basic Income style dividends are paid to all Alaskans. Essentially, the UBOF is a low-interest mortgage to invest in infrastructure and human growth that brings forward the benefits of a sovereign wealth fund to the present rather than waiting for it to accumulate over time.”

Full paper is available here. And here is the longer section on “The technicalities of a Universal Basic Opportunity Fund,” including building and administering the fund. ht Lauren

Tranlating randomized controlled trials into policy action

"A randomized experiment is performed,a statistically significant comparison is found, and then story time begins, and continues and continues—as if the rigor from the randomized experiment somehow suffuses through the entire analysis."

From a short paper by ANDREW GELMAN, who adds his analysis to the debate on the use of RCTs in policy development. Link.

The paper that Gelman is commenting on, by ANGUS DEATON and NANCY CARTWRIGHT, tackles misunderstandings and misuses of the form across disciplines:

"RCTs are both under- and over-sold. Oversold because extrapolating or generalizing RCT results requires a great deal of additional information that cannot come from RCTs; under-sold, because RCTs can serve many more purposes than predicting that results obtained in a trial population will hold elsewhere…

The gold standard or 'truth' view does harm when it undermines the obligation of science to reconcile RCTs results with other evidence in a process of cumulative understanding."

The Greatest Strategies


The inadequacy of individual informed consent

This week, an Australian college student noticed how data from Strava, a fitness-tracking app, can be used to discover the locations of military bases. Many outlets covered the news and its implications, including Wired and the Guardian. In the New York Times, Zeynep Tufekci’s editorial was characteristically insightful:

“Data privacy is not like a consumer good, where you click ‘I accept’ and all is well. Data privacy is more like air quality or safe drinking water, a public good that cannot be effectively regulated by trusting in the wisdom of millions of individual choices. A more collective response is needed.”

Link to the editorial.

Samson Esayas considers the collective nature of data privacy from a legal perspective:

"This article applies lessons from the concept of ‘emergent properties’ in systems thinking to data privacy law. This concept, rooted in the Aristotelian dictum ‘the whole is more than the sum of its parts’, where the ‘whole’ represents the ‘emergent property’, allows systems engineers to look beyond the properties of individual components of a system and understand the system as a single complex... Informed by the discussion about emergent property, the article calls for a holistic approach with enhanced responsibility for certain actors based on the totality of the processing activities and data aggregation practices."

Link to the paper. ht Jay

  • A Twitter note on Strava from Sean Brooks: “So who at Strava was supposed to foresee this? Whose job was it to prevent this? Answer is almost certainly no one…I’ve always hated the ‘data is the new oil’ metaphor, but here it seems disturbingly accurate. And ironically, organizations with something to hide (military, IC, corporate R&D) have the resource curse. They want to benefit from the extraction, but they also have the most to lose.” Link.
  • We mentioned Glen Weyl last week as a noteworthy economist engaging with ethical issues (see Beatrice Cherrier’s Twitter thread). A speculative paper he co-wrote on "data as labor" imagines a world in which companies paid users for their data. (We find the framing "data as labor" slightly misleading—Weyl's larger point seems to be about data as assets—the product of labor.) Link. ht Chris Kanich for bringing the two threads together on Twitter.
  • This Economist article also covers Weyl's paper: “Still, the paper contains essential insights which should frame discussion of data’s role in the economy. One concerns the imbalance of power in the market for data. That stems partly from concentration among big internet firms. But it is also because, though data may be extremely valuable in aggregate, an individual’s personal data typically are not.” Link.
  • A potentially exciting aspect of the GDPR is the right to data portability: "A free portability of personal data from one controller to another can be a strong tool for data subjects in order to foster competition of digital services and interoperability of platforms and in order to enhance controllership of individuals on their own data."

A Ha?


A flurry of articles in December and January assess the state of artificial intelligence

From Erik Brynjolfsson et al, optimism about productivity growth:

“Economic value lags technological advances.

“To be clear, we are optimistic about the ultimate productivity growth fueled by AI and complementary technologies. The real issue is that it takes time to implement changes in processes, skills and organizational structure to fully harness AI’s potential as a general-purpose technology (GPT). Previous GPTs include the steam engine, electricity, the internal combustion engine and computers.

“In other words, as important as specific applications of AI may be, the broader economic effects of AI, machine learning and associated new technologies stem from their characteristics as GPTs: They are pervasive, improved over time and able to spawn complementary innovations.”

Does banning the box increase hiring discrimination?

“Our results support the concern that BTB [Ban the Box] policies encourage racial discrimination: the black-white gap in callbacks grew dramatically at companies that removed the box after the policy went into effect. Before BTB, white applicants to employers with the box received 7% more callbacks than similar black applicants, but BTB increased this gap to 43%. We believe that the best interpretation of these results is that employers are relying on exaggerated impressions of real-world racial differences in felony conviction rates.”

Newly published by AMANDA AGAN and SONJA STARR, in line with their previous work on the same topic, available here.

  • These results bolster longstanding concerns about perverse consequences arising from ban the box legislation. (Similar studies include this one from 2006, and this one from 2016.) A 2008 paper provides a theoretical accompaniment to these worries, arguing that a privacy tradeoff is required to ensure race is not being used as a proxy for criminal history: “By increasing the availability of information about individuals, we can reduce decisionmakers’ reliance on information about groups.… reducing privacy protections will reduce the prevalence of statistical discrimination.” Link.
  • In a three part series from 2016, Noah Zatz at On Labor took on the perverse consequences argument and its policy implications, levelling three broad criticisms: “it places blame in the wrong place, it relies upon the wrong definition of racial equality, and it ignores cumulative effects.” Link.
  • A 2017 study of ban the box that focussed on the public sector—where anti-discrimination enforcement is more robust—found an increase in the probability of hiring for individuals with convictions and “no evidence of statistical discrimination against young low-skilled minority males.” Link.
  • California’s Fair Chance Act went into effect January 1, 2018, joining a growing list of fair hiring regulations in many other states and counties by extending ban the box reforms to the private sector. The law provides that employers can only conduct criminal background checks after a conditional offer of employment has been made. More on the bill can be found here.
  • Two posts on the California case, again by Zatz at On Labor, discuss several rich policy design questions raised by the “bright line” standards included in this legislation, and how they may interact with the prima facie standard of disparate impact discrimination: “Advocates fear, however, that bright lines would validate the exclusion of people on the wrong side of the line, despite individualized circumstances that vindicate them. But of course, the opposite could also be the case.” Link.
  • Tangentially related, Ben Casselman reports in the New York Times that a tightening labor market may be encouraging some employers to hire beyond the box—without legislative guidance. Link.

Higher minimum wages and the EITC may reduce recidivism

“Using administrative prison release records from nearly six million offenders released between 2000 and 2014, we use a difference-in-differences strategy to identify the effect of over two hundred state and federal minimum wage increases, as well as 21 state EITC programs, on recidivism. We find that the average minimum wage increase of 8% reduces the probability that men and women return to prison within 1 year by 2%. This implies that on average the wage effect, drawing at least some ex-offenders into the legal labor market, dominates any reduced employment in this population due to the minimum wage.”

Full paper by AMANDA Y. AGAN and MICHAEL D. MAKOWSKY here.

  • Jennifer Doleac responds, “The results in this new paper…definitely surprised me—my prior was that raising the min wage would increase recidivism.” She explains: “Those coming out of prison are very likely to be on the margin of employment (last hired, first fired). Given some disemployment effects, marginal workers are the ones who are going to be hurt. Amanda and Mike find that the positive effects of pulling some (higher-skilled?) offenders into the legal labor market outweigh those negative effects.” Link to Doleac’s Twitter thread.
  • One of the co-authors, Makowsky, adds, “The EITC, dollar for household dollar, generates larger effects [than minimum wage increases], but is hampered by its contingency on dependent children. This is one more reason to remove the contingency, extending it to everyone.” Link to Makowsky’s Twitter thread.
  • Another piece sourced from Makowsky’s thread: “The Impact of Living-Wage Ordinances on Urban Crime.” “Using data on annual crime rates for large cities in the United States, we find that living-wage ordinances are associated with notable reductions in property-related crime and no discernable impact on nonproperty crimes.” Link.
  • Noah Smith rounds up recent studies on increasing the minimum wage, many of which come to contradictory conclusions. "At this point, anyone following the research debate will be tempted to throw up their hands. What can we learn from a bunch of contradictory studies, each with its own potential weaknesses and flaws?" Link.

Anonymous Power Game


Nominations from top economists, including selections by Raj Chetty, Sendhil Mullainathan, and Angus Deaton

One favorite from this excellent round-up is by Hulten and Nakamura on metrics, selected by Diane Coyle (we previously sent her Indigo Prize paper):

Accounting for Growth in the Age of the Internet: The Importance of Output-Saving Technical Change by Charles Hulten and Leonard Nakamura

Main finding: Living standards may be growing faster than GDP growth.
Nominating economist: Diane Coyle, University of Manchester
Specialization: Economic statistics and the digital economy
Why?: “This paper tries to formalize the intuition that there is a growing gap between the standard measure of GDP, capturing economic activity, and true economic welfare and to draw out some of the implications.”

Robert Allen's "Absolute Poverty: When Necessity Displaces Desire" is another metrics-related piece on the list.

Also noteworthy, on the future of work:

Valuing Alternative Work Arrangements by Alexandre Mas and Amanda Pallais

Main finding: The average worker does not value an Uber-like ability to set their own schedule.
Nominating economist: Emily Oster, Brown University
Specialization: Health economics and research methodology
Why? “This paper looks at a question increasingly important in the current labor market: How do people value flexible work arrangements? The authors have an incredibly neat approach, using actual worker hiring to generate causal estimates of how workers value various employment setups.”

The Year in Review

INCOME SHARE AGREEMENTS Purdue, BFF, the national conversation “Long discussed in college policy and financing circles, income share agreements, or ISAs, are poised to become more mainstream.” That's from a September Wall Street Journal article. 2017 saw new pilots and the introduction of legislation in Congress, as well as the continued growth of Purdue’s Back a Boiler program, which was covered in PBS Newshour with JFI staff featured. Better Future Forward (incubated by JFI) was founded to originate ISAs and structure ISA pilots. Launched in February 2017 with support from the Arnold Foundation and the Lumina Foundation, BFF has formed partnerships with (and funded students through) Opportunity@Work, College Possible, and the Thurgood Marshall College Fund. Various research organizations are tracking ISAs closely: From the American Academy of Arts and Sciences, a 112-page report with "practical and actionable recommendations to improve the undergraduate experience": “What was once a challenge of quantity in American undergraduate education, of enrolling as many students as possible, is now a challenge of quality—of making sure that all students receive the rigorous education they need to succeed, that they are able to complete the studies they begin, and that they can do this affordably, without mortgaging the very future they seek to improve." Link to the full report. See page 72 for mention of ISAs. From the Miller Center at the University of Virginia (2016): "ISAs offer a novel way to inject private capital into higher education systems while striking a balance between consumer preference...
