Identification Of Treatment Effects With Mismeasured Imperfect Instruments, Desire Kedagni Jun 2019

Identification Of Treatment Effects With Mismeasured Imperfect Instruments, Desire Kedagni

Economics Working Papers

In this article, I develop a novel identification result for estimating the effect of an endogenous treatment using a proxy of an unobserved imperfect instrument. I show that the potential outcomes distributions are partially identified for the compliers. Therefore, I derive sharp bounds on the local average treatment effect. I write the identified set in the form of conditional moments inequalities, which can be implemented using existing inferential methods. I illustrate my methodology on the National Longitudinal Survey of Youth 1979 to evaluate the returns to college attendance using tuition as a proxy of the true cost of going to ...


Notes On The Gridlab-D Household Equivalent Thermal Parameter Model, Leigh Tesfatsion, Swathi Battula May 2019

Notes On The Gridlab-D Household Equivalent Thermal Parameter Model, Leigh Tesfatsion, Swathi Battula

Economics Working Papers

GridLAB-D (GLD) is an agent-based platform, developed by researchers at Pacific Northwest National Laboratory, that permits users to accurately simulate the state dynamics of power distribution systems at time scales ranging from sub-seconds to years. The purpose of this study is to present, in careful comprehensive form, a complete analytical state-space control representation for a version of the GLD Household Equivalent Thermal Parameter Model as support documentation for model users. This model is a physically-based implementation of a household with multiple price-responsive and conventional appliances whose thermal dynamics are determined over successive days by resident appliance usage and external weather ...


Black Lives Matter As Resistance To Systemic Anti-Black Violence, Dominique Thomas May 2019

Black Lives Matter As Resistance To Systemic Anti-Black Violence, Dominique Thomas

Journal of Critical Thought and Praxis

Black Lives Matter has emerged within the last five years as a significant movement for social change. Serving as an ideological and political intervention, Black Lives Matter organizes to protect and advocate for Black lives and Black communities. This article will outline Black Lives Matter as a movement and how it is a form of resistance as against systemic anti-Black violence. Centuries of Black resistance against epistemic, structural/policy, and physical violence is the historical context of Black Lives Matter. Two prominent aspects of the movement intersectionality and decentralized leadership. The implications for resistance are that BLM is a new ...


Radical Rejections Of Violence: Resisting Anti-Muslim Racism, Umaymah Mohammad, Isa Naveed, Dennis L. Rudnick May 2019

Radical Rejections Of Violence: Resisting Anti-Muslim Racism, Umaymah Mohammad, Isa Naveed, Dennis L. Rudnick

Journal of Critical Thought and Praxis

This paper argues that by expanding and critiquing the definition of violence with relation to Islamophobia, implicit manifestations of Islamophobia, anti-Muslim Racism, and structural violence can be exposed. Through the work of the Muslim Youth Collective, we frame anti-Muslim racism as structural violence, and provide considerations for how Muslim communities may actualize resistance in response.


Rallying Over Balloting: The Origins Of Millennial Activism, Nolan Higdon May 2019

Rallying Over Balloting: The Origins Of Millennial Activism, Nolan Higdon

Journal of Critical Thought and Praxis

Activism by U.S. millennials, such as the March for Our Lives, Occupy, and Black Lives Matter, has reversed a national decline in civic engagement. Much of the scholarship has focused on how, not why, millennials participate in activism. This qualitative study of 121 purposely sampled millennial participants seeks to identify the origins of millennial activism. This study operates from a generational lens. Interviews of each participant from 2015-2017 went through two cycles of coding to reveal five progenitors of millennial activism: Family and Friends, Institutions and Organizations, Encounters with Activism, Media and Popular Culture, and Hate and Harm. The ...

A Correction For Regression Discontinuity Designs With Group-Specific Mismeasurement Of The Running Variable, Otávio Bartalotti, Quentin Brummet, Steven Dieterle May 2019

A Correction For Regression Discontinuity Designs With Group-Specific Mismeasurement Of The Running Variable, Otávio Bartalotti, Quentin Brummet, Steven Dieterle

Economics Working Papers

When the running variable in a regression discontinuity (RD) design is measured with error, identification of the local average treatment effect of interest will typically fail. While the form of this measurement error varies across applications, in many cases the measurement error structure is heterogeneous across different groups of observations. We develop a novel measurement error correction procedure capable of addressing heterogeneous mismeasurement structures by leveraging auxiliary information. We also provide adjusted asymptotic variance and standard errors that take into consideration the variability introduced by the estimation of nuisance parameters, and honest confidence intervals that account for potential misspecification. Simulations ...

Rational Ecosystem-Based Fisheries Management: An Application To The Gom Commercial Reef Fish Fishery, Quinn Weninger May 2019

Rational Ecosystem-Based Fisheries Management: An Application To The Gom Commercial Reef Fish Fishery, Quinn Weninger

Economics Working Papers

Ecosystem-based fisheries management (EBFM) seeks to integrate the complexity of real-world marine ecosystems into the design of fisheries policies and regulations. EBFM is practiced currently with the help of complex ecosystem process models that track and simulate ecosystem function and outcomes under competing model formulations and management plans. To maintain tractability, the fishing sector component of process models maintain restrictive assumptions for multiple species harvesting technologies, fishing behavioral rules, and fishing sector responses to changing stock conditions. Predictions of fishing sector-ecosystem interaction obtained under these assumptions can grossly misinform EBFM policy design. An alternative rational fishing model is presented and ...


Neonicotinoids In U.S. Maize: Insecticide Substitution Effects And Environmental Risk, Edward D. Perry, Giancarlo Moschini May 2019

Neonicotinoids In U.S. Maize: Insecticide Substitution Effects And Environmental Risk, Edward D. Perry, Giancarlo Moschini

CARD Working Papers

This study exploits a novel dataset containing more than 89,000 farm-level surveys over a 17-year period to investigate how neonicotinoid seed treatments in maize, now ubiquitous, have affected the use of other insecticides. Neonicotinoid insecticides are the most used class of insecticides in the world, but they are controversial because of their high toxicity to honeybees. In the United States, maize production accounts for the majority of neonicotinoid use, mostly as seed treatments. We find that neonicotinoids substituted for other major insecticides: plots planted with neonicotinoid- treated seeds were 52% and 47% less likely to be treated with a ...


Adoption Of Secure Pork Supply Plan Biosecurity By U.S. Swine Producers, Christopher C. Pudenz, Lee L. Schulz, Glynn T. Tonsor May 2019

Adoption Of Secure Pork Supply Plan Biosecurity By U.S. Swine Producers, Christopher C. Pudenz, Lee L. Schulz, Glynn T. Tonsor

Economics Publications

There is mounting concern about the negative animal health and supply chain consequences of animal disease outbreaks in the United States. Recent disease outbreaks have drawn attention to the need for additional understanding of biosecurity efforts to reduce disease frequency, spread, and impact. Biosecurity is a key component of the Secure Pork Supply (SPS) Plan designed to provide business continuity in the event of a foreign animal disease outbreak as well as help protect operations from endemic diseases. Core biosecurity recommendations outlined in the SPS Plan are a written site-specific biosecurity plan and implementation of a perimeter buffer area and ...


Family Legacy Of Diabetes-Related Behaviors: An Exploration Of The Experiences Of African American Parents And Adult Children, Brianna Routh, Tera R. Hurt, Donna M. Winham, Lorraine Lanningham-Foster Apr 2019

Family Legacy Of Diabetes-Related Behaviors: An Exploration Of The Experiences Of African American Parents And Adult Children, Brianna Routh, Tera R. Hurt, Donna M. Winham, Lorraine Lanningham-Foster

Human Development and Family Studies Publications

African Americans are at higher risk of developing type 2 diabetes mellitus (T2DM), and this risk may be influenced by familial experiences and cultural norms throughout the life course. This led us to conduct this study of 20 African American families with strong histories of T2DM to explore familial complexities that prevent or help manage diabetic symptoms. Experiences were analyzed inductively through individual family profiles created using content-analytic summaries. When profiles were further analyzed for emerging and theoretically informed data patterns, two themes emerged: (a) family interactions characterized by T2DM-related actions and communication patterns, and (b) intergenerational patterns of openness ...

Agricultural and Biosystems Engineering Publications

Problems at the nexus of Food, Energy and Water Systems (FEWS) are among the most complex challenges we face. Spanning simple to complex temporal, geographic, social, and political framings, the questions raised at this nexus require multidisciplinary if not transdisciplinary approaches. Answers to these questions must draw from engineering, the physical and biological sciences, and the social sciences. Practical solutions depend upon a wide community of stakeholders, including industry, policymakers, and the general public. Yet there are many obstacles to working in a transdisciplinary environment: unfamiliar concepts, specialized terminology, and countless “blind” spots. Graduate education occurs in disciplinary ‘silos', often ...

The Will Of The People: Measuring Social Divides In Multi-Dimensional Choice Settings, Sunanda Roy, Kuan Chuen Wu, Abhijit Chandra Mar 2019

The Will Of The People: Measuring Social Divides In Multi-Dimensional Choice Settings, Sunanda Roy, Kuan Chuen Wu, Abhijit Chandra

Economics Working Papers

The paper studies profile components that cause plurality scores to differ from scores under other positional methods. We focus especially on the differences between plurality tallies and the Borda Count. We show that these profile components consist of an equal number of voters supporting a specific candidate in the first and last places. In particular they have an equal number of voters supporting a specific preference order and its reverse. In light of recent attention on partisanship and political polarization, it is important to have measures of such profiles and an assessment of how much they contribute to positional tallies ...


A Negative Effect Of A Contractive Pose Is Not Evidence For The Positive Effect Of An Expansivepose: Comment On Cuddy, Schultz, And Fosse (2018), Marcus Crede Mar 2019

A Negative Effect Of A Contractive Pose Is Not Evidence For The Positive Effect Of An Expansivepose: Comment On Cuddy, Schultz, And Fosse (2018), Marcus Crede

Psychology Publications

Cuddy,Schultz and Fosse (2018) present the results of p-curve analyses that are interpreted as providing "clear evidential value for power posing effects”. This commentary highlights that the vast majority of the studies included in the p-curve analyses were not designed in a way that could speak to the efficacy of power poses relative to a normal or neutral pose. Further, I discuss how the few studies that were designed to shed light on this issue indicate that any overall effect of physical pose on feelings of power, emotions, affect, and self-evaluations is almost entirely due to the negative effect ...

Design/methodology/approach The authors describe a meta-analytic review of the relationship between transformational leadership and employee performance (task performance and OCBs) using data from over 57,000 individuals, 215 samples and 34 countries. The authors examine whether this relationship is moderated by the cultural values and practices of the country in which the study was located – after first controlling for methodological factors.

Findings The authors find that cultural values and practices moderate ...


Bean Counters: The Effect Of Soy Tariffs On Change In Republican Vote Share Between The 2016 And 2018 Elections., Olga Chyzh, Robert B. Urbatsch Mar 2019

Bean Counters: The Effect Of Soy Tariffs On Change In Republican Vote Share Between The 2016 And 2018 Elections., Olga Chyzh, Robert B. Urbatsch

Political Science Publications

How do trade wars affect presidential support? President Trump's aggressive tariffs on China despite his largely rural electoral support base provide a unique opportunity to analyze the relationship between international trade policy and domestic support. If trade-related considerations were ever decisive to American voters, the stark decrease in soy prices, a direct effect of Trump-initiated tariffs immediately preceding the 2018 midterm election, serves as a critical test for studying their effect. This letter shows a robust inverse relationship between county-level soybean production and the change in Republican vote share between the 2016 and 2018 congressional elections.


Wild Bootstrap For Fuzzy Regression Discontinuity Designs: Obtaining Robust Bias-Corrected Confidence Intervals, Yang He, Otávio Bartalotti Mar 2019

Wild Bootstrap For Fuzzy Regression Discontinuity Designs: Obtaining Robust Bias-Corrected Confidence Intervals, Yang He, Otávio Bartalotti

Economics Working Papers

This paper develops a novel wild bootstrap procedure to construct robust bias- corrected valid confidence intervals (CIs) for fuzzy regression discontinuity designs, providing an intuitive alternative to existing analytical methods. The CIs generated by this procedure are valid under conditions similar to the standard analytical procedures used in the empirical literature. Simulations provide evidence that this new method is at least as accurate as the analytical corrections when applied to a variety of data generating processes featuring heteroskedasticity, endogeneity and clustering. Finally, we demonstrate its empirical relevance by revisiting Angrist and Lavy (1999) analysis of class size on student outcomes.


Identification Of Resource Extraction Technologies When The Resource Stock Is Unobservable, Quinn Weninger, Larry Perruso, Helle Bunzel Feb 2019

Identification Of Resource Extraction Technologies When The Resource Stock Is Unobservable, Quinn Weninger, Larry Perruso, Helle Bunzel

Economics Working Papers

This paper consistently estimates the structural properties of a fishery resource extraction technology. We overcome two ubiquitous features of fisheries data generating processes that invalidate classical estimators: unobservability by the researcher (but partial observability by fishermen) of the fish stock, and endogenous production decisions that vary with private information about stock abundance and economic variables. We adopt methods used in fisheries stock assessment to control for unobserved stock effects on productivity. A nonlinear instrumental variables estimator controls for endogenous choices of the output mix. The approach is applied to the US Gulf of Mexico commercial reef fish fishery. Comparison with ...


Telling A Good Story: The Effects Of Memory Retrieval And Context Processing On Eyewitness Suggestibility, Jessica A. Lapaglia, Jason C.K. Chan Feb 2019

Telling A Good Story: The Effects Of Memory Retrieval And Context Processing On Eyewitness Suggestibility, Jessica A. Lapaglia, Jason C.K. Chan

Psychology Publications

Witnesses are likely to describe a crime many times before testifying or encountering misinformation about that crime. Research examining the effect of retrieval on later suggestibility has yielded mixed results. LaPaglia and Chan manipulated whether misinformation was presented in a narrative or misleading questions, and they found that retrieval increased suggestibility when misinformation was presented in a narrative, but reduced suggestibility when the same misinformation was presented in questions. In the current study, we aimed to address why these differences occurred. Specifically, we examined whether contextual detail and narrative coherence during misinformation exposure influenced the relation between retrieval and suggestibility ...


Evaluating Motivational Interviewing And Habit Formation To Enhance The Effect Of Activity Trackers On Healthy Adults’ Activity Levels: Randomized Intervention, Laura D. Ellingson, Jeni E. Lansing, Kathryn J. Deshaw, Karissa L. Peyer, Yang Bai, Maria Perez, L. Alison Phillips, Gregory Welk Feb 2019

Evaluating Motivational Interviewing And Habit Formation To Enhance The Effect Of Activity Trackers On Healthy Adults’ Activity Levels: Randomized Intervention, Laura D. Ellingson, Jeni E. Lansing, Kathryn J. Deshaw, Karissa L. Peyer, Yang Bai, Maria Perez, L. Alison Phillips, Gregory Welk

Psychology Publications

Background: While widely used and endorsed, there is limited evidence supporting the benefits of activity trackers for increasing physical activity; these devices may be more effective when combined with additional strategies that promote sustained behavior change like motivational interviewing (MI) and habit development. Objective: This study aims to determine the utility of wearable activity trackers alone or in combination with these behavior change strategies for promoting improvements in active and sedentary behaviors. Methods: A sample of 91 adults (48/91 female, 53%) was randomized to receive a Fitbit Charge alone or in combination with MI and habit education for 12 ...


Motherhood, Migration, And Self-Employment Of College Graduates, Zhengyu Cai, Heather M. Stephens, John V. Winters Feb 2019

Motherhood, Migration, And Self-Employment Of College Graduates, Zhengyu Cai, Heather M. Stephens, John V. Winters

Economics Working Papers

Women face unique challenges in starting and running their own businesses and may have differing motives to men for pursuing self-employment. Previous research suggests that married women with families value the flexibility that self-employment can offer, allowing them to balance their family responsibilities with their career aspirations. This may be especially true for college graduates, who tend to have more successful businesses. Access to childcare may also affect their labor force decisions. Using American Community Survey microdata, we examine how birth-place residence, a proxy for access to extended family and child care, relates to self-employment and hours worked for college-graduate ...


The Economic Impact Of The Health Sector On The Economy Of Appanoose County, Iowa, Daniel Otto, Georgeanne Artz Feb 2019

The Economic Impact Of The Health Sector On The Economy Of Appanoose County, Iowa, Daniel Otto, Georgeanne Artz

Economics Working Papers

The importance of medical and health facilities as community service providers is well

established, yet their role in generating significant economic impacts for the community is less often acknowledged. Health care facilities, such as hospitals and nursing homes, not only employ many people with a sizeable payroll, but also draw a large number of people from rural areas into the community for medical services. In this study, we attempt to identify and measure the economic importance of the health sector for the economy of Appanoose County, Iowa. The specific objectives of this report are to:

1. summarize the direct economic ...


Accounting For The International Quantity-Quality Trade-Off, Juan Carlos Cordoba, Xiying Liu, Marla Ripoll Jan 2019

Accounting For The International Quantity-Quality Trade-Off, Juan Carlos Cordoba, Xiying Liu, Marla Ripoll

Economics Working Papers

We investigate what accounts for the observed international differences in schooling and fertil- ity, and draw lessons for the underlying sources of cross-country income differences. For this purpose, we extend a life-cycle dynastic model to include features relevant for schooling and fertility choices. Our approach allows for country-specific human capital technologies in addi- tion to differences in TFP, public education policies, and demographic factors. We find that differences in human capital production functions, specifically in the degree of complementarity of educational investments, are key to match schooling data, and result in novel estimates of human capital stocks and TFP levels ...


Evaluation Of An Intelligent Team Tutoring System For A Collaborative Two-Person Problem: Surveillance, Alec Ostrander, Desmond Bonner, Jamiahus Walton, Anna Slavina, Kaitlyn M. Ouverson, Adam Kohl, Stephen Gilbert, Michael Dorneich, Anne Sinatra, Eliot H. Winer Jan 2019

Evaluation Of An Intelligent Team Tutoring System For A Collaborative Two-Person Problem: Surveillance, Alec Ostrander, Desmond Bonner, Jamiahus Walton, Anna Slavina, Kaitlyn M. Ouverson, Adam Kohl, Stephen Gilbert, Michael Dorneich, Anne Sinatra, Eliot H. Winer

Industrial and Manufacturing Systems Engineering Publications

This paper describes the development and evaluation of an Intelligent Team Tutoring System (ITTS) for pairs of learners working collaboratively to monitor an area. In the Surveillance Team Tutor (STT), learners performed a surveillance task in a virtual environment, communicating to track hostile moving soldiers. This collaborative problem solving task required significant communication to achieve the common goal of perfect surveillance. In a pilot evaluation, 16 two-person teams performed the task within one of three feedback conditions (Individual, Team, or None) across four trials each. The STT used a unique approach to filtering feedback so that teams in both individual ...


The Influence Of Parental Alcoholism On Parent–Adolescent Relationships From Adolescence Into Emerging Adulthood: A Qualitative Inquiry, Sarah E. Bickelhaupt, Brenda J. Lohman, Tricia K. Neppl Jan 2019

The Influence Of Parental Alcoholism On Parent–Adolescent Relationships From Adolescence Into Emerging Adulthood: A Qualitative Inquiry, Sarah E. Bickelhaupt, Brenda J. Lohman, Tricia K. Neppl

Human Development and Family Studies Publications

Exposure to parental alcoholism can inhibit a child’s ability to become a successfully functioning young adult. Based on qualitative

interviews, this study provides a deeper understanding of how those parent–adolescent relationships are associated with risky internalizing and externalizing behaviors. This qualitative study explores the lives of 13 young adult children of alcoholics (ACOAs) and provides a unique perspective through an adaptive developmental approach by evaluating emerging adults who were ACOAs and successfully functioning. Compelling findings emerged with respect to how young adults define alcoholism and being a child of alcoholism and how the parent–adolescent relationship adapts in ...


Has Specialization Put A Limit On How Far Cattle Contracting Can Go?, John Crespi, Tina L. Saitone Jan 2019

Has Specialization Put A Limit On How Far Cattle Contracting Can Go?, John Crespi, Tina L. Saitone

Agricultural Policy Review

I N 1776 Scottish philosopher Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations, or as it is better known, The Wealth of Nations. In many mundane ways, Smith merely chronicled the burgeoning European industries he was observing; but, in doing so, he helped spread a revolutionary thinking about how factories could take advantage of specialization. Smith’s discussion of a visit to a pin factory has been re-told so often that many people probably know the story without knowing the source. The story goes like this: If you were to make a pin ...


African Swine Fever In China: An Update, Wendong Zhang, Dermot J. Hayes, Yongjie Ji, Minghao Li, Tao Zlong Jan 2019

African Swine Fever In China: An Update, Wendong Zhang, Dermot J. Hayes, Yongjie Ji, Minghao Li, Tao Zlong

Agricultural Policy Review

LAST NOVEMBER, we wrote an article (Shao et al. 2018) documenting the development of African Swine Fever (ASF) in China and its impacts on regional hog and pork prices. Since then, ASF has continued to ravage China’s hog industry with 62 new cases from November 1, 2018 to March 27, 2019, resulting in a total of 114 cases. The total inventory of hog factories with ASF outbreaks has increased from 61,214 to 319,726 (click here to see an animated map of ASF cases in China). The pace of the outbreaks has somewhat slowed down from more than ...


The Yin And Yang Of Agricultural Trade, Lee L. Schulz, Chad Hart Jan 2019

The Yin And Yang Of Agricultural Trade, Lee L. Schulz, Chad Hart

Agricultural Policy Review

IT’S A fascinating, but uncertain, time in the agricultural markets. Global and US supplies of agricultural products are at or near record levels. At the same time, global demand for agricultural products continues to grow, pressured by both population and income growth. Markets work to distribute the products across the globe, and government policies can definitely shape that distribution. Myriad new trade agreements, trade disputes, and tariffs introduced over the last 15 months are reshaping global agricultural trade 􀏐lows. Some of that reshaping has been beneficial to US producers, while some of it has been harmful. Trade policy does ...
