The Effects Of Student-Teacher Ratio On Test Scores: Applying Ceteris Paribus To California And Massachusetts Schools, Laira Aggarwal

Undergraduate Economic Review

This paper seeks to analyze the impact of student-teacher ratio on test scores in California and Massachusetts. Since student-teacher ratio is just one of the variables affecting students’ learning outcomes, other attributes were taken into account for a comprehensive analysis. These attributes included percent of English learners, average district income, percent of students on free or reduced lunch, and expenditures per student. The data sets for both states were assessed both inherently and with ceteris paribus approach. The results indicated that while student-teacher ratio does affect test scores, other classroom variables have a significantly greater influence on students’ learning outcomes.

Adaptive Learning Courseware As A Tool To Build Foundational Content Mastery: Evidence From Principles Of Microeconomics, Karen Gebhardt

Current Issues in Emerging eLearning

Adaptive courseware has the potential to increase content mastery through assessment and personalized remediation. In this study, content mastery is determined by assessment items developed in alignment to learning outcomes using Bloom’s Taxonomy. This study tracks freshmen and sophomore students enrolled in the foundations course, Principles of Microeconomics at Colorado State University. The researcher finds that students who complete adaptive assignments show higher mastery on formative assessments.

Farm Programs, Payments And Prospects, Bradley D. Lubben

Cornhusker Economics

The USDA Farm Service Agency (FSA) began issuing payments to producers in October for Price Loss Coverage (PLC) and Agriculture Risk Coverage (ARC) programs for the 2017 crop year. While these farm program payments had provided substantial cash flow to help buffer falling market price and farm income projections in the past three years, the current programs will provide relatively little cash flow for now and for the coming year. Only the ad hoc trade assistance payments and the outlook for new farm programs and decisions in 2019 may provide potential relief from the current outlook.

Black Panther: Thrills, Postcolonial Discourse, And Blacktopia, Giana M. Eckhardt

Markets, Globalization & Development Review

Black Panther challenges traditional depictions of African nations in film by showcasing the fictional African country of Wakanda as a global technological leader, its citizens as being comfortable in global settings, and by having Wakanda deliver social aid to the US, reversing the typical global flow of assistance. Wakanda is depicted as a Blacktopia, where societies thrive beyond the reach of white supremacy as they have not been subject to colonization.

The Socialist World In The Second Age Of Globalization: An Alternative History?, James M. Robertson

Markets, Globalization & Development Review

The history of the Second Age of Globalization (from 1945 through to the present) has traditionally been told through the lens of either the industrially advanced First World, or, more critically, the developing countries of the Third World. Less is known about the experience of globalization in the so-called “Second World”, the socialist states of the Soviet Union and its Eastern European satellites. The following review essay draws on recent work in the history of globalization to show that, contrary to long-held assumptions that socialism was an autarkic system that cut countries off from the wider world, post-war socialist countries …

Winning War In A Globalized World: Utilizing Women & Gender Initiatives In 21st Century Conflict, Emerald M. Archer

Markets, Globalization & Development Review

Three thousand years of recorded history has reserved warfighting for men and, in 2017, we continue to rely on ideas of hegemonic masculinity to understand who participates in war. However, women have played a vital role in the context of warfare from its inception. In the twenty-first century, women’s service is critical to the types of conflicts militaries regularly confront – specifically, counter insurgency and peacekeeping operations. The intersection of gender and security today provides new routes to peaceful prosperity globally. Applying gender initiatives to militaries – whether it means creating a gender balanced force, the integration of women into …

Chinese And European Financial Systems: Instability Drivers And Contagion Channels, Paolo Canofari, Alessandro Del Ponte

Political Science Faculty Articles and Research

This paper identifies systemic risk levels in the Eurozone and China. We first analyze the political and macro-financial factors underlying potential financial instability in both currency areas. Then, we examine the impact of a possible breakup of the Eurozone on the Chinese financial system and the risk of redenomination of Chinese assets expressed in Euros. Finally, considering the increasing credit gap in the Chinese economy and the enduring political instability in several Eurozone countries, we warn against a possible opening of contagion channels between China and Europe.

Applying Interconnected Game Theory To Analyze Transboundary Waters: A Case Study Of The Kura-Araks Basin, Marianna Khachaturyan, Karina A. Schoengold

Cornhusker Economics

A number of environmental problems are international in nature, including many water management issues. Rivers, for example, do not recognize political boundaries. Therefore, pollution generated in one country can affect neighboring countries, while water extraction in an upstream country can affect water flow and water availability in a downstream country. The situation creates an interdependency among countries, which might lead to disputes over the management of transboundary water. Therefore, coordination among the countries is necessary for effective management of these transboundary resources.

The focus of a recently published study (Khachaturyan and Schoengold, 2018) is the transboundary Kura-Araks Basin (see Figure …

Adjusting For Guessing And Applying A Statistical Test To The Disaggregation Of Value-Added Learning Scores, Ben O. Smith, Jamie Wagner

Economics Faculty Publications

In 2016, Walstad and Wagner developed a procedure to split pre-test and post-test responses into four learning types: positive, negative, retained, and zero learning. This disaggregation is not only useful in academic studies; but also provides valuable insight to the practitioner: an instructor would take different mitigating actions in response to zero versus negative learning. However, the original disaggregation is sensitive to student guessing. This article extends the original work by accounting for guessing and provides adjusted estimators using the existing disaggregated values. Further, Monte Carlo simulations of the adjusted learning type estimates are provided. Under certain assumptions, an instructor …

Determinants Of Usaid Spending, Austin J. Moser

Student Research – Stevenson Center

This paper examines the determinants of USAID’s foreign aid disbursements from 2002-2016. Three noteworthy findings emerge. First, USAID foreign aid is based more on political considerations rather than the policies of recipient countries. Second, foreign aid is determined by location and political history. Third, this pattern emerges across all categories of USAID disbursements.

Coordination And Evolutionary Dynamics: When Are Evolutionary Models Reliable?, Daniel Graydon Stephenson

ESI Publications

This study reports a continuous-time experimental test of evolutionary models in coordinated attacker–defender games. It implements three experimental treatment conditions: one with strong coordination incentives, one with weak coordination incentives, and one with zero coordination incentives. Each treatment exhibits identical equilibrium predictions but distinct evolutionary predictions. Observed behavior was tightly clustered around equilibrium under both the zero coordination treatment and the weak coordination treatment but widely dispersed from equilibrium under the strong coordination treatment. This result was anticipated by explicitly dynamic models but not by conventional stability criteria. In contrast to the widely maintained assumption of sign-preservation, subjects frequently switched …

Variation Among Populations In The Immune Protein Composition Of Mother's Milk Reflects Subsistence Pattern, Laura D. Klein, Jincui Huang, Elizabeth A. Quinn, Melanie A. Martin, Alicia A. Breakey, Michael Gurven, Hillard Kaplan, Claudia Valeggia, Grazyna Jasienska, Brooke Scelza, Carlito B. Lebrilla, Katie Hinde

ESI Publications

Lay Summary: Adaptive immune proteins in mothers’ milk are more variable than innate immune proteins across populations and subsistence strategies. These results suggest that the immune defenses in milk are shaped by a mother’s environment throughout her life.

Background and objectives: Mother’s milk contains immune proteins that play critical roles in protecting the infant from infection and priming the infant’s developing immune system during early life. The composition of these molecules in milk, particularly the acquired immune proteins, is thought to reflect a mother’s immunological exposures throughout her life. In this study, we examine the composition of innate …

Do Negative Random Shocks Affect Trust And Trustworthiness?, Hernán Bejarano, Joris Gillet, Ismael Rodriguez-Lara

ESI Publications

We report data from a variation of the trust game aimed at determining whether (and how) inequality and random shocks that affect wealth influence the levels of trust and trustworthiness. To tease apart the effect of the shock and the inequality, we compare behavior in a trust game where the inequality is initially given and one where it is the result of a random shock that reduces the second mover's endowment. We find that first‐movers send less to second‐movers but only when the inequality results from a random shock. As for the amount returned, second‐movers return less when they are …

The Supply Side Determinants Of Territory And Conflict, Jordan Adamson, Erik O. Kimbrough

ESI Working Papers

What determines the geographic extent of territory? We microfound and extend Boulding’s “Loss of Strength Gradient” to predict the extensive and intensive margins of conflict across space. We show how economies of scale in the production of violence and varying costs of projecting violence at a distance combine to affect the geographic distribution of conflict and territory. We test and probe the boundaries of this model in an experiment varying the fixed costs of conflict entry. As predicted, higher fixed costs increase the probability of exclusive territories; median behavior closely tracks equilibrium predictions in all treatments.

Evaluating Ethiopia’S Development Progress, Sambath Jayapregasham, Matthäus Schuster, Ruben Tjon-A-Meeuw

Undergraduate Economic Review

Ethiopia, Africa’s second most-populated nation is well on its way to becoming one of its wealthiest nations as it charges forward on its path to development. The big question is whether this growth is sustainable. To tackle this question, we will discuss its development strategy using a popular comparison to that of China. We will then offer an appraisal of the current state of the country. Finally, we will evaluate the future of Ethiopia, as it continues its current path – evaluating the potential upsides and risks it faces moving forward.

Moral Hazard And Adverse Selection In The Insurance Market, Kevin Willardsen

Applied Econometrics Workshops

Willardsen presented on his upcoming article with the same title. The abstract from this paper is as follows:

Understanding the relative significance of adverse selection and moral hazard is important in determining effective policy for insurance markets. Separate identification of these two effects, empirically, is difficult. To overcome this limitation, this paper uses experimental methods to examine how adverse selection and moral hazard separately affect agent performance in a real-effort task. In particular, we explore how agent behavior (effort in the task) changes across a baseline with no insurance option, a treatment where individuals can choose to purchase insurance, and …

Doing Well By Doing Good In The Fight Against Malnutrition And Hunger, Konstantinos Giannakas, Amalia Yiannaka

Cornhusker Economics

Technological innovation and the conduct of innovating firms are key weapons in the fight against hunger and the pursuit of food security around the world. Agricultural biotechnology seems uniquely equipped, if not destined, to spearhead the effort to combat malnutrition and hunger around the world by conferring significant agronomic benefits to producers and by having the ability to enhance both the resistance of plants to environmental stresses and the quality and nutritional value of food. Research that was recently published by the Center of Agricultural and Food Industrial Organization- Policy Research Group at the University of Nebraska Lincoln analyzes the …

A Bit Like Cash: Understanding Cash-For-Bitcoin Transactions Through Individual Vendors, Stephanie J. Robberson, Mark R. Mccoy

Journal of Digital Forensics, Security and Law

As technology improves and economies become more globalized, the concept of currency has evolved. Bitcoin, a cryptographic digital currency, has been embraced as a secure and convenient type of money. Due to its security and privacy for the user, Bitcoin is a good tool for conducting criminal trades. The Financial Crimes Enforcement Network (FinCEN) has regulations in place to make identification information of Bitcoin purchasers accessible to law enforcement, but enforcing these rules with cash-for-Bitcoin traders is difficult. This study surveyed cash-for-Bitcoin vendors in Oklahoma, Texas, Arkansas, Missouri, Kansas, Colorado, and New Mexico to determine personal demographic information, knowledge of …

Is Uber A Substitute Or Complement For Public Transit?, Jonathan D. Hall, Craig Palsson, Joseph Price

Economics and Finance Faculty Publications

How Uber affects public transit ridership is a relevant policy question facing cities worldwide. Theoretically, Uber’s effect on transit is ambiguous: while Uber is an alternative mode of travel, it can also increase the reach and flexibility of public transit’s fixed-route, fixed-schedule service. We estimate the effect of Uber on public transit ridership using a difference-in-differences design that exploits variation across U.S. metropolitan areas in both the intensity of Uber penetration and the timing of Uber entry. We find that Uber is a complement for the average transit agency, increasing ridership by five percent after two years. This average effect …

Experimental Research On Contests, Roman M. Sheremeta

ESI Working Papers

Costly competitions between economic agents are modeled as contests. Researchers use laboratory experiments to study contests and test comparative static predictions of contest theory. Commonly, researchers find that participants’ efforts are significantly higher than predicted by the standard Nash equilibrium. Despite overbidding, most comparative static predictions, such as the incentive effect, the size effect, the discouragement effect and others are supported in the laboratory. In addition, experimental studies examine various contest structures, including dynamic contests (such as multi-stage races, wars of attrition, tug-of-wars), multi-dimensional contests (such as Colonel Blotto games), and contests between groups. This article provides a short review …

Technological Change, Automation And Employment: A Short Review Of Theory And Evidence, K. V. Ramaswamy

International Review of Business and Economics

A selective survey of recent papers in the area of technological change, automation and employment is presented. The objective is to convey analytical ideas and the empirical evidence that have informed studies in this area of contemporary policy relevance. Automation occurs when a machine does work that might previously have been done by a person. How robots and automation affect the availability of jobs for labor force? There are very few emerging studies that address the issue with detailed data on robots usage and employment in different sectors of the economy. Based on our review of available studies and empirical …

Impact Of Infrastructure On Economic Growth: A Panel Data Approach Using Pmg Estimator, Esra Kabaklarli, Fatih Mangir, Bansi Sawhney

International Review of Business and Economics

Growth theory asserts that infrastructure investments promote economic growth by improving the quality of life and increasing private sector productivity . Transport services, water utility services and telecommunication services provide better facilities to attract FDI (foreign direct investment) and increase productivity across sectors. The aim of this article is to analyze whether transport infrastructure investments have a strong effect on the economic growth. It also attempts to analyze the differential impact of each type of infrastructural spending on economic growth.
