Background
Market share refers to the percentage of total sales in an industry generated by a particular company. This measurement is pivotal for businesses and economists to evaluate competitive positioning and commercial success.
Historical Context
The concept of market share gained prominence with the expansion of large corporations and the development of antitrust and competition laws in the late 19th and early 20th centuries. The Sherman Antitrust Act (1890) in the U.S., for example, aimed to curb monopolies by regulating market share.
Definitions and Concepts
Market share is often expressed as a percentage and calculated using the formula:
\[ \text{Market Share} = \left( \frac{\text{Company’s Sales}}{\text{Total Market Sales}} \right) \times 100 \]
Factors affecting market share include brand loyalty, product quality, advertising, and pricing strategies.
Major Analytical Frameworks
Classical Economics
Classical economists focus on the mechanisms of free markets and typically underplay the relevance of market share in the long-term equilibria of perfectly competitive markets.
Neoclassical Economics
Neoclassical economics refines classical theory by incorporating detailed analysis of firm behavior, including how companies seek to increase market share through resource allocation and strategies to achieve competitive advantages.
Keynesian Economics
Keynesian models tend to be more macro-focused, often sidelining market share unless it has broader implications for aggregate demand and employment.
Marxian Economics
Marxian economists view market share through the lens of capital concentration and its impacts on class relationships and labor exploitation.
Institutional Economics
Institutional economists emphasize the role of various institutions, such as technology and business laws like antitrust regulations, in shaping market share dynamics.
Behavioral Economics
Behavioral economics investigates how psychological factors might affect consumers’ choices, thereby influencing a firm’s ability to grow or sustain its market share.
Post-Keynesian Economics
Post-Keynesians might explore market share in terms of economic fluctuations and the impact on business cycles, emphasizing constraints and inefficiencies within markets.
Austrian Economics
Austrian economics, centered on individual choice and market processes, views changes in market share as a natural outcome of entrepreneurial discovery and innovation.
Development Economics
In the context of emerging markets, development economists study market share to understand how newly industrializing companies impact local and global markets.
Monetarism
Monetarists’ focus on the supply of money may lead to exploring market share in terms of how monetary policy influences competitive dynamics and firm performance.
Comparative Analysis
Comparing varying methods of calculating and interpreting market share can reveal nuances in competitive strategy across different markets and industries. Regional and global comparisons illuminate the importance of defining the relevant market carefully to avoid misinterpretation, especially for regulatory decisions.
