Sticky Prices

Understanding sticky prices, their causes, and implications in various economic frameworks.

Background

Sticky prices refer to the phenomenon where prices of goods and services are slow to adjust in response to changes in supply and demand, or production costs. This rigidity in prices can occur despite significant fluctuations in underlying economic conditions.

Historical Context

The concept of sticky prices has been observed throughout economic history, particularly during periods of economic uncertainty. It gained prominence during the Great Depression and has been a crucial factor in various macroeconomic models ever since.

Definitions and Concepts

Sticky prices, also known as “price rigidity,” are prices that do not change quickly or easily in response to economic signals. This can result from several factors, including menu costs (the cost of changing prices), and price point attractiveness (psychological pricing strategies).

Major Analytical Frameworks

Classical Economics

Classical economics typically assumes flexibility in prices and wages, with markets quickly adjusting to equilibrium. Sticky prices challenge this assumption and suggest that markets do not always self-correct efficiently.

Neoclassical Economics

Neoclassical economics acknowledges sticky prices, especially as a short-term phenomenon. It’s recognized that prices can be sticky due to adjustment costs and informational constraints.

Keynesian Economics

Keynesian economics places significant importance on sticky prices, highlighting them as a cause of non-clearing markets and unemployment. According to Keynesians, sticky prices can result in prolonged periods of disequilibrium.

Marxian Economics

While Marxian economics primarily focuses on the dynamics between labor and capital, sticky prices can be seen as an aspect of the struggles over the distribution of surplus value, especially in monopolistic or oligopolistic markets.

Institutional Economics

Institutional economics examines sticky prices by considering the role of social norms and organizational practices in inflexible pricing. Institutions can create environments where adhering to stable prices is necessary.

Behavioral Economics

Behavioral economics studies sticky prices through human psychology, examining why firms may avoid price changes due to cognitive biases, fairness considerations, or fear of customer backlash.

Post-Keynesian Economics

Post-Keynesian thought extends Keynesian ideas, strongly emphasizing the role of sticky prices and wages in creating inefficiencies and unemployment, advocating for active policy measures to address these issues.

Austrian Economics

Austrian economics tends to downplay the importance of sticky prices, focusing instead on the role of time preferences, capital structure, and entrepreneurial discovery in the market process.

Development Economics

In development economics, sticky prices can be particularly problematic. They can exacerbate the impact of external shocks on developing economies which often lack strong institutional frameworks to buffer the effects.

Monetarism

Monetarism acknowledges sticky prices more as a short-term disruption and focuses on the role of monetary policy in determining overall economic stability and inflation.

Comparative Analysis

Different economic schools of thought interpret sticky prices through varying lenses, shifting the focus from market self-regulation to government intervention as a remedy for inefficiencies.
