Objectives and Topics

This thesis examines the equilibrium theory of Alfred Marshall and assesses its relevance within modern economics by analyzing its foundational assumptions and testing them against the Sraffian critique.

• Characterization of Marshall's fundamental assumptions and his view of the economic actor.
• Analysis of market mechanisms and the differentiation between short-term and long-term equilibria.
• Evaluation of Piero Sraffa's critique regarding Marshall's theory of returns and market competition.
• Discussion on the consistency of Marshall's partial equilibrium concept in light of contemporary economic challenges.

Excerpt from the Book

Summary of Chapters

1. Introduction: Outlines the historical debate surrounding the concept of economic equilibrium and introduces the objective to evaluate Marshall's relevance using the Sraffian critique.

2. Economic equilibrium: Details Marshall's core concepts, including his definition of economic science, his view of man, and the distinction between market periods.

2.1 Marshall's perspective of the market mechanism: Examines Marshall’s interpretation of competition and market dynamics, specifically highlighting his deviation from Walrasian atomistic models.

2.2 Short- and long-term equilibrium: Discusses how time periods influence equilibrium, where supply is fixed in the short run and becomes increasingly elastic due to production costs in the long run.

2.3 Summary: Provides a recap of the Marshallian model, focusing on the transition from short-term to long-term adjustment mechanisms and the concept of quasi-rent.

3. Critique of Marshall's theory of equilibrium: Presents Piero Sraffa's fundamental criticism of Marshall's value theory and his skepticism regarding the consistency of supply and demand curves.

3.1 Critical appraisals: Offers a final assessment of Marshall's theories, considering modern factors like external shocks and technical progress that were not part of the original model.

4. Conclusion and outlook: Synthesizes the findings, confirming Marshall's status as a "modern classic" while noting the necessity of adapting these theories to globalized, dynamic markets.

Frequently Asked Questions

What is the central focus of this thesis?

The thesis provides a critical analysis of Alfred Marshall's equilibrium theory, exploring its theoretical structure and examining its applicability to modern economic conditions.

What are the primary themes discussed?

The work covers Marshall's view of human action, his differentiation of economic time periods, the role of competition, and the theoretical challenges posed by Piero Sraffa.

What is the primary research goal?

The research aims to determine the extent to which Marshall's economic concepts are reflected in modern economics and whether he can be classified as a "modern classic".

Which scientific method is utilized?

The thesis utilizes a comparative and critical literature analysis, specifically using the Sraffian critique as a foundation to evaluate Marshall's system.

What does the main body cover?

The main body breaks down Marshall's concepts of wealth and action, analyzes his market mechanisms under varying time horizons, and contrasts his work with Sraffa's criticisms.

Which keywords define this work?

Key terms include Alfred Marshall, equilibrium, supply and demand, Sraffian critique, neoclassicism, and market mechanisms.

How does Marshall differ from Walras regarding price?

Unlike Walras, who views price as an independent variable determined by an auctioneer, Marshall views quantity as the primary adjustment factor in a monetary economy.

What does the "quasi-rent" represent in Marshall's model?

Quasi-rent is a temporary surplus that occurs in the short run when market prices exceed prime costs, representing an income that does not correspond to standard production costs.

Why is Sraffa's critique significant for this analysis?

Sraffa’s critique highlights potential inconsistencies in Marshall's "long-period" analysis, particularly challenging the independence of supply and demand curves in the presence of constant returns to scale.
