Background
Temporary equilibrium refers to a state of short-term balance in an economic model. In such models, which often consist of a series of short time periods, equilibrium is achieved temporarily within each period as agents form expectations about future economic variables.
Historical Context
The concept of temporary equilibrium has its roots in dynamic economic modeling. Historically, economists have sought to understand how equilibrium might be achieved not only in a single, static period but also across a succession of periods. This approach allows for a more nuanced examination of economic dynamics over time.
Definitions and Concepts
- Temporary Equilibrium: A static equilibrium within a given, short period in a dynamic model of the economy, achieved based on current decisions and expectations about future periods.
- Overlapping Generations Model (OLG): An economic model that illustrates the economy in a series of overlapping time periods, commonly used to study issues like social security and national debt.
- Static Equilibrium: A state where supply equals demand within a single period without consideration of future periods.
- Perfect Foresight: An assumption whereby agents have complete and accurate knowledge of the future.
- Rational Expectations: A hypothesis that posits individuals form forecasts about the future based on all available information, including understanding of economic models and policies.
Major Analytical Frameworks
Classical Economics
Classical economics primarily deals with long-term equilibrium states and is less concerned with temporary spells, focusing on natural laws of market function and laissez-faire policies.
Neoclassical Economics
Neoclassical economics has incorporated temporary equilibrium by considering how agents form rational expectations and engage in intertemporal optimization.
Keynesian Economics
Temporary equilibrium plays a significant role in Keynesian models, where short-run fluctuations and adjustments are critical in determining overall economic performance, especially in times of economic distress.
Marxian Economics
While focusing more on long-term trends related to capital accumulation and class struggle, Marxian economists may analyze temporary equilibrium to understand short-term imbalances and crises.
Institutional Economics
This perspective might use temporary equilibrium to explore how institutions and rules impact short-term market functioning and expectations.
Behavioral Economics
Behavioral economics often critiques models of temporary equilibrium by highlighting how real agent behavior deviates from perfect rationality or forward-looking rational expectations.
Post-Keynesian Economics
Post-Keynesians emphasize the role of uncertainty and expectations in achieving temporary equilibrium and critique the reliance on rational expectations in standard models.
Austrian Economics
Austrians might be skeptical of temporary equilibrium concepts, emphasizing the role of entrepreneurial action and market process over statical snapshots of equilibrium.
Development Economics
Understanding temporary equilibrium can be essential when analyzing economic policies in developing countries, where short-term policy impacts might differ from long-term growth trajectories.
Monetarism
Monetarists study temporary equilibrium within the context of monetary policy’s short-term impacts on prices and output, emphasizing money supply control to navigate these temporary states.
Comparative Analysis
Different economic schools of thought interpret temporary equilibrium in various ways, from market adjustments in the neoclassical framework to the pivotal role of expectations and policy responses in Keynesian economics.
