How does your kindergarten classroom affect your earnings? Evidence from Project Star

In Project STAR, 11,571 students in Tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade. This article evaluates the long-term impacts of STAR by linking the experimental data to administrative records. We first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27, college attendance, home ownership, and retirement savings. We then document four sets of experimental impacts. First, students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes. Class size does not have a significant effect on earnings at age 27, but this effect is imprecisely estimated. Second, students who had a more experienced teacher in kindergarten have higher earnings. Third, an analysis of variance reveals significant classroom effects on earnings. Students who were randomly assigned to higher quality classrooms in grades K–3—as measured by classmates' end-of-class test scores—have higher earnings, college attendance rates, and other outcomes. Finally, the effects of class quality fade out on test scores in later grades, but gains in noncognitive measures persist.     

MacroJournal—Turning Students into Practitioners

Incorporating currents events into an economics curriculum is a goal of many dedicated instructors. The benefits of doing so are obvious. Unfortunately, the costs associated with implementation are nontrivial. In the following, the authors introduce an experiential writing assignment, called the MacroJournal, which streamlines the process of incorporating current events into a macroeconomics course. The costs for the instructor are mitigated by a repeated structure of questioning and a well-defined grading rubric. By completing the assignment, students have an opportunity to become practitioners and link current events to classroom theory.     

Tweeting Your Way to Improved #Writing, #Reflection,and #Community

Economics appears to be lagging behind other fields in the adoption of Web 2.0 technologies in the classroom. Twitter is an online microblogging utility, permitting posts of up to 140 characters called tweets. The utility is rapidly making its way into secondary and post-secondary classrooms as a complement to traditional instruction and an active learning tool. In this article, the author describes how Twitter was employed as a complement to traditional lecture in a small macroeconomics principles course (the instrument is applicable to courses at any level). The brevity of the tweets forces students to express their thoughts concisely and is believed to develop reflection and writing skills while expanding the class community.     

Migrant peers in the classroom: Is the academic performance of local students negatively affected?

This paper provides the first causal estimates of the impact of internal migrant peers on the academic performance of local students in developing countries. By exploiting the random assignment of students to classes within a school, I find that migrant peers have large and negative effects on the academic performance of local students in China and the negative spillover effects are concentrated among male students and among local students in large cities. The investigation of the underlying mechanisms suggests that the negative migrant spillover effects may come from the worsened learning environment or from the adjustment of teachers’ pedagogical practices in response to the migrant composition in the classroom.     

A classroom experiment in monetary policy

The authors propose a classroom experiment implementing a simple version of a New Keynesian model suitable for courses in intermediate macroeconomics and money and banking. Students play as either the central bank or members of the private sector. The central banker sets interest rates to meet twin objectives for inflation and the output gap or to meet only an inflation target. In both settings, private sector agents are concerned with correctly forecasting the inflation rate. The authors show that an experiment implementing this setup is feasible and yields results that enhance understanding of the New Keynesian model of monetary policy. They propose alternative versions where the central bank is replaced by a policy rule and provide suggestions for discussing the experimental results with students.     

Comment

How well does competitive theory explain the outcome in experimental markets. The authors examined the results of a large number of classroom trading experiments that used a pit-trading design found in Experiments with Economic Principles, an introductory economics textbook by Bergstrom and Miller. They compared experimental outcomes with predictions of competitive-equilibrium theory and with those of a simple profit-splitting theory. Neither theory was entirely successful in explaining the data, although in the first rounds of trading there was significant profit splitting and, as traders became more experienced, outcomes were closer to those predicted by competitive theory.     

AN EMPIRICAL MODEL OF LEARNING UNDER AMBIGUITY: THE CASE OF CLINICAL TRIALS*

This article presents a two‐dimensional structural model of learning under ambiguity in the context of clinical trials. Clinical trials offer an ideal environment to study learning under ambiguity. The randomization process found in these studies leaves patients uncertain to their actual group assignment. Therefore, patients cannot immediately attribute changes in health to the experimental drug. The article proposes the use of “learning instrumental variables” to simultaneously update patients’ beliefs of the treatment effect and group assignment. Patient learning is found to be faster when observable side effects are incorporated to account for the uncertainty in group assignment.     

A Rent-Seeking Experiment for the Classroom

Abstract: Recent research has demonstrated that active learning techniques improve student comprehension and retention of abstract economic ideas such as rent seeking. Instructors can reinforce the concept of rent seeking with a classroom game, particularly one involving real money. The authors improve upon a game first introduced by Goeree and Holt (1999) and later expanded upon by Bischoff and Hofmann (2002). The authors present a version of the game in which students participate in an all-pay auction, risking their own money, and discover first hand the potential inefficiencies of rent seeking. The authors suggest extensions of the rent-seeking game, including discussions of social welfare effects, equity, campaign finance reform, tax simplification, and congressional reforms designed to limit the influence of rent seeking in the economy.     

Enhancing economic literacy of classroom teachers

For the past two summers, the Division of Education and the Division of Business and Economics at Indiana University at Kokomo have collaborated to produce an intense teamtaught summer economics course for pre-service education majors and in-service classroom teachers. The dual emphasis on content and application allows economics to integrate every aspect of the classroom and allows Praxis achievement. This paper explores the essential nature of Praxis in making the content or practice link—so critical for successful implementation of economics in K-12 classrooms. To determine their attitudes toward and knowledge of economics education, a pretest and post-test format was adopted. In addition, the institutional enhancers and inhibitors that dramatically affected the development and implementation of the new course of study are presented. This paper was presented at the Forty-Fourth International Atlantic Economic Society Conference in Philadelphia, Pennsylvania, October 9–12, 1997. Discussants' comments are incorporated.     

合作学习打破大学英语课堂沉默的有效性研究

大学生消极的课堂沉默是多种因素共同作用的结果，不利于学生英语综合应用能力的培养和提高。合作学习以建构主义和人本主义理论为基础，强调学生的主体参与和生生之间的互动合作，既是一种有效的学习模式，也是一种新型的教学组织形式。以定量和定性的方式探讨了合作学习和传统教学模式跟课堂沉默的关系。研究表明，“以学生为中心”的合作学习对打破大学英语课堂沉默有明显效果，而“以教师为中心”的传统教学模式不仅会导致课堂沉默，而且会在一定程度上加重课堂沉默的程度。     

Improved grade outcomes with an e-mailed “grade nudge”

Information provided at the moment a person makes a decision can influence behavior in predictable ways. The United Kingdom's Behavioural Insights Team have used this idea to help improve the insulation of lofts, collect taxes, and even reduce litter. The authors of this article developed software that appends a personalized message to each assignment in the class regarding the student's current grade. This “grade nudge” explains precisely how the assignment will impact the student's final grade given their current standing in the class. Through a randomized trial, the authors show that the nudge improves student homework performance by about four percentage points.     

Credible assignments in coordination games

This paper uses the experimental method to examine an arbiter's ability to determine the outcome of two-person coordination games. All of the arbiter's assignments in the experiments were strict equilibrium points, but some assignments violated payoff-dominance or symmetry. An assignment that corresponds to the game's outcome is a credible assignment. The experiments test the hypothesis that an assignment to a strict equilibrium is a credible assignment. Our subjects did not find the individual rationality and mutual consistency of an equilibrium assignment to be sufficient reason for implementing the assignment when doing so conflicts with payoff-dominance or symmetry.     

Your Place in Space: Classroom Experiment on Spatial Location Theory

The authors detail an urban economics experiment that is easily run in the classroom. The experiment has a flexible design that allows the instructor to explore how congestion, zoning, public transportation, and taxation levels determine the bid–rent function. Heterogeneous agents in the experiment compete for land use using a simple auction mechanism. Using the data that is collected, a bid–rent function is derived, and the experimental treatment is altered over the course of three sessions to uncover core concepts in urban economics. Moreover, this provides a tangible experience that can be used to help undergraduates relate to urban issues such as the steep rent gradient found around many larger colleges and universities.     

An endogenous equilibrium game on traffic congestion externalities

Traffic congestion and road tolls are familiar economic concepts for most undergraduates; however, students often have difficulty explaining exactly how theoretical principles like externalities and social welfare are related to their real-world experiences, such as driving. The authors present a classroom exercise to demonstrate how congestion externalities are generated, the effects on private and social welfare, and how appropriately priced tolls can address congestion externalities. Students are asked to evaluate outcomes in five different driving scenarios, with and without congestion or tolls. The authors offer discussion questions to make the activity engaging and informative. They report the results of their efforts to administer the exercise. This 75-minute exercise is appropriate for introductory or intermediate microeconomics, political economy, or environmental economics classes of various sizes.     

A Survey of Economic Understanding in U.S. High Schools

The recent widespread adoption of online competitions in economic education provides a unique opportunity to make frequent assessments of economic literacy in U.S. classrooms. In this survey, student responses to test items from the Test of Economic Literacy (TEL) are used to create economic concept and content area achievement benchmarks. These benchmarks provide an interim renorming of the TEL and allow the authors to gauge the status of economic understanding among high school students. The data also allow the authors to compare learning outcomes between regular and advanced economics classes. Finally, the authors find that students in advanced economics classes significantly outperform students in regular classes.

Revisiting unemployment in intermediate macroeconomics: A new approach for teaching Diamond-Mortensen-Pissarides

The authors present a version of the Diamond-Mortensen-Pissarides model of unemployment that is accessible to undergraduates and preserve the dynamic structure of the original model. The model is solvable in closed form using basic algebra and admits a graphical representation useful for illustrating a variety of comparative statics. They show how to use the model to teach the effects of labor market policies, advancements in Internet technology, and labor market dynamics. Supplementary materials such as teaching tips, a classroom experiment, and online resources including a JavaScript-based simulation tool, U.S. data used to make figures, and practice problems are provided.     

Investors' Personality Influences Investment Decisions: Experimental Evidence on Extraversion and Neuroticism

The authors analyze the impact of individuals' degree of extraversion and neuroticism on their decision making in an experimental asset market. To establish this link between research on experimental asset markets and social psychology the authors use a unique approach that combines a questionnaire designed to assess individuals' degree of extraversion and neuroticism and an experimental asset market to assess individual financial decision making. The dataset combines 364 undergraduate business students' questionnaire responses and their trading behavior in the asset market. The authors find that extraversion and neuroticism significantly influence individuals' behavior in the experimental asset market. Specifically, more extraverted individuals pay higher prices for financial assets and they buy more financial assets when assets are overpriced than less extraverted individuals do. More neurotic individuals hold less risky assets in their financial portfolios than less neurotic individuals do. Although a large part of the explanatory power appears to be driven by gender differences, the authors still find significant impact of extraversion and neuroticism after controlling for gender effects. The study findings suggest that further research on financial markets could benefit from including personality of market participants as a crucial explanatory factor.     

Evaluating the magnitude and the stakes of peer effects analysing science and math achievement across OECD

What follows is an exercise aimed at estimating peer effects' impact on science and math test scores of secondary school students surveyed in 1995 by the International Education Agency across OECD countries. It is also to discuss their importance for educational policy, particularly regarding the highly sensitive issue of ability-grouping. Using this unique international database. This study assesses the magnitude of the peer effect relative to more traditional inputs. Referring to education policy stakes, we control for the presence of increasing or decreasing return. This study also checks for cross effects in order to determine whether peer effects matter more to low or high SES pupils, and whether their final impact on achievement is affected by the underlying level of heterogeneity within the group. Using a methodology, which a priori accounts for the clustering of the data within countries and schools/classrooms - i.e. fixed/random effect or hierarchical model - our analysis indicates that peer effects are strong determinants of both math and science achievement relative to individual SES and other school inputs. The presence of increasing of decreasing returns is not obvious. But we find systematic evidence that low-ability pupils are more sensitive to peer group characteristics. By contrast, this study also find that - for a given level of the peer effect - higher heterogeneity comes at a certain cost. In brief, these results provide no systematic evidence regarding grouping policies.
