Using a sample of 70,399 published p-values from 192 meta-analyses, we empirically estimate the counterfactual distribution of p-values in the absence of any biases. Comparing observed p-values with counterfactually expected p-values allows us to estimate how many p-values are published as being statistically significant when they should have been…

This study investigates whether online homework improves learning in principles of microeconomics. It contributes to the related literature in two dimensions. First, it tests whether there is a positive association between students' performances on homework and exams. Importantly, it measures learning through exams that were given shortly after…

The authors describe an asymmetric information demonstration that assigns students different probabilities of incurring healthcare expenses. In each round, students choose whether to purchase insurance; then, the instructor randomly determines who gets "sick." After computing insurer profits, students help determine a new insurance price…

Instructors may use low-cost, light-touch strategies to help students achieve optimal effort in demanding upper-level courses. The authors of this study exploit an intervention that provides a series of personalized feedback emails to students about their relative performance, which is tied to approving messages or tips that encourage improvement.…

The undergraduate economics curricula for most of the 793 U.S. colleges and universities that conferred an economics bachelor's degree in 2019 are described in this article. Besides updating the prevalence of the economics major core requirements and their differences by institution type, the authors record new information on requirement…

The aim of this study is to analyze the use of Problem-Based Learning (PBL) in learning Microeconomics. It aims to answer the following research questions: What are the experiences of undergraduate students who studied with Problem-Based Learning (PBL)? Is this strategy useful at the undergraduate level? Does PBL really motivate students? Does it…

This article describes a conceptual and empirical approach for estimating a human capital production function of child development that incorporates mother- or child-fixed effects. The use of mother- or child-fixed effects is common in this applied economics literature, but its application is often inconsistent with human capital theory. We…

This article contributes to the literature on interdisciplinary teaching by describing, analyzing, and evaluating an interdisciplinary intervention while students are still gaining disciplinary grounding. The intervention bridges courses in microeconomics and ethics. It focuses on the travelling concepts of voluntariness and value in a potential…

The author investigates the learning efficiency of economic experiments, an innovative instructional tool that re-creates the outside world within the classroom. This tool enables the instructor to create an economic environment whereby students experience how their decisions and interactions create the market forces predicted by the economic…

In the early 1940s, Black artist Jacob Lawrence painted a series of 60 panels that are now collectively called "The Migration Series." The panels tell the story of how Black Americans migrated from the South to the North, beginning with World War I. The panels provide an uncommon example of the intersection of economics, Black American…

This study highlights the importance of metacognitive awareness of economics students and examines the relationship between Problem-Based Learning (PBL) and Metacognitive awareness among economics students. This research was conducted in the Faculty of Economics, Universitas Negeri Malang of Indonesia by employing economics students as the subject…

Playfulness as a learning technique is applied into the present research in a group of adult learners. Initially, a game scenario was designed and implemented for the subject of microeconomics. Following a qualitative research methodology, through observation and interviews with ten participants before and after the playful activity, the results…

Students of introductory economics are often able to predict changes in equilibrium price correctly on standardized assessments, but make consistent errors in predicting changes in equilibrium quantity. To examine the reasons for this pattern, the authors collected open-ended explanations written by students and categorized their reasoning using a…

Decades of research has shown that spacing practice trials over time can improve later memory, but there are few concrete recommendations concerning how to optimally space practice. We show that existing recommendations are inherently suboptimal due to their insensitivity to time costs and individual- and item-level differences. We introduce an…
