The pith

System dynamics models that capture feedback effects can improve economics education by revealing complex causal loops in economic behavior.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper argues that feedback thinking and system dynamics modeling should be added to economics curricula because they explain the behavior of social and economic systems through models that include complex causality and feedback. It demonstrates the idea with a pricing feedback model, recounts the authors' experiences teaching these methods in different economics programs, and proposes a four-level course hierarchy while noting tradeoffs instructors must weigh. A reader would care because standard economics teaching often presents static or linear views that miss the dynamic loops driving real outcomes like price adjustments or market instability.

Core claim

The central claim is that system dynamics methodology, which builds models capturing complex causality and feedback effects in economic systems, offers concrete opportunities to strengthen economics education. This is shown first through a pricing feedback model that highlights the method's benefits, then through the authors' varied teaching experiences that depend on student preparation and instructor background, a proposed four-level hierarchy for progressive integration, and explicit discussion of the pedagogical tradeoffs that must be managed when introducing the approach.

What carries the argument

The pricing feedback model, which demonstrates how system dynamics captures feedback loops and delays in economic pricing decisions.

Load-bearing premise

That the benefits shown by the pricing model and the authors' personal teaching experiences will produce better student learning outcomes when applied in other economics programs, without comparative empirical data.

What would settle it

A controlled comparison of student performance on tests measuring understanding of dynamic economic processes, such as price oscillations or policy side effects, between classes using the system dynamics approach and matched classes using only traditional methods.

read the original abstract

System dynamics is a methodology that is widely used in many academic fields. It explains the behavior of social and economic systems with models that capture complex causality and feedback effects. This 'practice paper' discusses the opportunities and barriers for introducing feedback thinking and system dynamics models in the economics curriculum. We start by providing a pricing feedback model that illustrates some of the benefits that system dynamics can provide in enhancing economics education. Then we summarize the experiences of each of the authors in teaching system dynamics on economics educational programs. This includes different approaches to teaching economics with system dynamics that depend on the learning objectives, the preparation of students, and the background of the instructor. We also develop a four-level course hierarchy for using system dynamics in economics teaching. We then point out the tradeoffs that instructors must consider as they introduce new pedagogies for delivering economics material. Finally, we provide some concluding comments with some suggestions for future work. The expected audiences for this paper are instructors as well as graduate students who are considering academia as a profession.

Referee Report

2 major / 2 minor

Summary. The manuscript is a practice-oriented paper advocating the integration of feedback thinking and system dynamics (SD) modeling into economics education. It opens with a pricing feedback model intended to illustrate conceptual benefits such as capturing complex causality and feedback effects, summarizes the authors' qualitative teaching experiences across different economics programs, proposes a four-level course hierarchy tailored to learning objectives and student preparation, discusses instructor tradeoffs when adopting new pedagogies, and closes with suggestions for future work. The target audience is economics instructors and graduate students considering academic careers.

Significance. If the illustrative model and hierarchy can be shown to improve student comprehension of dynamic economic phenomena, the paper would offer practical value for curriculum design in a field that often relies on static or equilibrium-focused approaches. The concrete pricing example and structured levels provide accessible entry points, and the tradeoff discussion supplies realistic implementation advice. These elements represent a strength in grounding the proposal in specific teaching contexts rather than abstract advocacy.

major comments (2)
  1. [pricing feedback model section] The pricing feedback model (introduced in the opening section and used to support the central claim of educational enhancement) is presented as demonstrating benefits through its stock-flow and feedback structure, yet the manuscript supplies no student learning outcome data, pre/post assessments, or controlled comparisons to standard economics instruction. Without such evidence, the assertion that the model enhances understanding of causality and dynamics rests on conceptual description alone and does not substantiate the broader claim that SD improves economics education.
  2. [teaching experiences and course hierarchy section] The summary of the authors' teaching experiences and the proposed four-level course hierarchy (detailed after the model) are based on qualitative personal accounts without quantification of outcomes, controls for student preparation or instructor background, or comparative metrics. This leaves the hierarchy and the claim that different approaches depend on learning objectives as proposals rather than empirically grounded recommendations, which is load-bearing for the paper's guidance to instructors.
minor comments (2)
  1. [abstract] The abstract could more explicitly distinguish between the illustrative purpose of the pricing model and the empirical status of the claimed educational benefits.
  2. [figures] If diagrams of the pricing model or hierarchy are included, ensure all variables, loops, and level distinctions are labeled consistently with the accompanying text.

  1. Referee: [pricing feedback model section] The pricing feedback model (introduced in the opening section and used to support the central claim of educational enhancement) is presented as demonstrating benefits through its stock-flow and feedback structure, yet the manuscript supplies no student learning outcome data, pre/post assessments, or controlled comparisons to standard economics instruction. Without such evidence, the assertion that the model enhances understanding of causality and dynamics rests on conceptual description alone and does not substantiate the broader claim that SD improves economics education.

    Authors: We agree with the referee that the manuscript does not include empirical data such as student learning outcomes or controlled comparisons. The pricing feedback model is presented as an illustrative example to show how system dynamics modeling can capture feedback effects and complex causality in economic contexts, which is often challenging with traditional static models. The paper does not claim empirical substantiation of improved education outcomes but rather uses the model to highlight conceptual advantages. In the revised manuscript, we will explicitly note the illustrative nature of the example and reference the suggestions for future empirical work in the conclusions. This addresses the concern by aligning the claims more precisely with the content provided. revision: yes

  2. Referee: [teaching experiences and course hierarchy section] The summary of the authors' teaching experiences and the proposed four-level course hierarchy (detailed after the model) are based on qualitative personal accounts without quantification of outcomes, controls for student preparation or instructor background, or comparative metrics. This leaves the hierarchy and the claim that different approaches depend on learning objectives as proposals rather than empirically grounded recommendations, which is load-bearing for the paper's guidance to instructors.

    Authors: The referee correctly observes that the teaching experiences are qualitative and the four-level hierarchy is a proposal based on the authors' experiences. As described in the abstract, this is a practice paper summarizing personal teaching experiences across different programs and proposing a hierarchy that depends on learning objectives, student preparation, and instructor background. We do not present it as empirically validated with quantitative metrics or controls. To improve clarity, we will revise the relevant sections to emphasize that these are proposals and reflections intended to provide practical guidance to instructors, rather than definitive recommendations. We will also suggest that future research could include more systematic evaluations. This maintains the paper's focus while responding to the call for grounding. revision: partial

Circularity Check

0 steps flagged

No circularity: illustrative model and experiences are self-contained

full rationale

The paper is a practice-oriented discussion that introduces a pricing feedback model solely as an illustration of conceptual benefits, summarizes the authors' separate teaching experiences, and proposes a four-level course hierarchy as a pedagogical framework. No equations, fitted parameters, or predictions appear that reduce by construction to quantities defined within the paper or via self-citation chains. The central claims rest on qualitative examples and external literature rather than any self-definitional loop, fitted-input prediction, or load-bearing uniqueness theorem imported from the authors' prior work. This satisfies the default expectation for non-circular papers.
