Introduction
Realism vs. Instrumentalism in Economic Models—within the intricate domain of economic inquiry, delineates a profound dialectical Tension concerning the Nature and Purpose of economic theorisation. This Dichotomy invites a contemplative engagement with economic models, wherein Realism posits that such constructs ought to mirror the ontological Structure of economic reality, aspiring to authenticity and Verisimilitude. In contrast, Instrumentalism espouses a more pragmatic utility, contending that the primary Function of an economic model resides in its efficacy as a tool for Prediction, unencumbered by the Necessity to embody or reflect the true essence of the phenomena it seeks to illuminate. Herein lies a discourse that transcends mere functionality, engaging deeply with the epistemological underpinnings of economic Science.
Language
The nominal "Realism vs. Instrumentalism in Economic Models," when parsed, highlights a dualistic framework within the discourse of Economic Methodology. Realism, a Noun derived from the adjective "real," stems from the Latin "realis," meaning "relating to things" or "practical," and is rooted in the Proto-Indo-European *res-, which connotes the Idea of a tangible object or entity. It evokes a philosophical stance asserting that models should reflect true aspects of the World. Instrumentalism, juxtaposed with realism, originates from the noun "instrument," through Old French "instrument," and Latin "instrumentum," meaning "tool" or "implement." This term derives from the Proto-Indo-European root *streu-, indicating a means of arrangement or Construction and suggests a viewpoint where models are merely Tools for prediction rather than Truth depiction. In the etymological unfolding, economic models, plural noun Phrase, emerges from "economy" and "model," where "economy" is from the Greek "oikonomia" (household Management) and "model" from Latin "modulus" (measure, standard). Here, "realism" and "instrumentalism" delineate a theoretical dichotomy, while "economic models" connote structured simulations or representations employed for analysis and Interpretation. The synthesis of these terms narrates a beyond their nominal definitions, instigating a methodological Reflection on their practical and theoretical applications. The etymological paths of these terms uncover their foundational linguistic elements and Trace the shifts in meaning that have influenced their Current usage in philosophical and analytical contexts. This elaboration illustrates the persistence of ancient linguistic roots within modern discourse without straying into the nominal origin influences.
Genealogy
Realism vs. Instrumentalism in Economic Models, a conceptual duality within economic methodology, has undergone significant Evolution since its inception, Shaping debates about the nature of economic Theory. Rooted in the philosophical discourse of scientific realism and instrumentalism, this dichotomy addresses whether economic models should be evaluated based on their descriptive accuracy of real-world phenomena (realism) or their predictive utility (instrumentalism). The origins of this debate can be traced back to the works of philosophers such as Pierre Duhem and Willard Van Orman Quine, who questioned the nature of scientific theories, while Milton Friedman’s seminal essay "The Methodology of Positive Economics" (1953) played a critical role in popularizing instrumentalism. In this framework, Friedman argued that the unrealistic assumptions of economic models are irrelevant as long as the models yield accurate predictions, reflecting the instrumentalist view. Conversely, realism advocates for models whose assumptions closely mirror reality, rooted in the belief that Understanding the causal mechanisms is crucial for robust economic analysis. Over the years, this dichotomy has influenced how economists perceive the validity and applicability of theoretical constructs, with both approaches often simultaneously influencing economic practices. In academic discourse, realism has often been mistakenly conflated with Empiricism, while instrumentalism has been critiqued for its perceived detachment from reality, highlighting the complexities and potential misuses of these terms. The debate intersects with broader philosophical discussions on the nature of scientific theories and their role in understanding the world, impacting related fields such as econometrics, Behavioral Economics, and policy analysis. As economic models continue to adapt amid evolving societal challenges, the realism vs. instrumentalism debate persists, reflecting ongoing tensions between theoretical rigor and practical applicability, and contributing to an intellectual Context that Values both philosophical inquiry and empirical relevance.
