Equilibrium and disequilibrium perspectives on regional labor migration
Journal of Regional Science
|January 1, 1993
Summary
This study reviews labor migration models in the US, distinguishing between equilibrium and disequilibrium approaches. It proposes new tests for models that account for population stock dynamics and different types of equilibrium.
Area of Science:
- Economics
- Sociology
- Demography
Background:
- Labor migration models are crucial for understanding population dynamics.
- Existing models often lack nuanced distinctions between equilibrium types and stock-flow interactions.
Purpose of the Study:
- To review alternative models of US labor migration.
- To propose novel testing methodologies for migration models.
- To differentiate between temporal and market-clearing equilibrium in migration.
Main Methods:
- Comparative analysis of existing labor migration models.
- Development of alternative statistical tests for migration models.
- Focus on stock-flow interactions in regional population dynamics.
Main Results:
- Identified limitations in current equilibrium and disequilibrium migration models.
- Proposed tests that explicitly incorporate stock-flow dynamics.
- Highlighted the importance of distinguishing temporal vs. market-clearing equilibrium.
Conclusions:
- The proposed tests offer a more robust evaluation of labor migration models.
- Accounting for stock-flow interactions enhances model accuracy.
- Clarifying equilibrium definitions is vital for migration research.

02:20Dynamic Equilibrium
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...
01:04Oscillations about an Equilibrium Position
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so because...
01:30Categories of Equilibrium
Equilibrium is a crucial concept in physics, enabling us to understand how forces interact with bodies to produce no or constant motion. In two-dimensional equilibrium, force systems can be classified into different categories based on their characteristics.
One of the categories of equilibrium is collinear equilibrium, which involves forces acting along a straight line. This type of equilibrium requires only one force equation in the direction of the forces, as the other equations are...

01:28Conditions of Equilibrium
Equilibrium refers to a state where a rigid body is not subjected to any translational or rotational motion. This state is achieved when the force and couple acting on a rigid body equal zero. When the system of external forces results in a net effect equivalent to zero, the rigid body is considered to be in equilibrium.
Internal forces are not considered for conditions of equilibrium because they occur in equal and opposite pairs within the body, effectively canceling each other. As a result,...

01:23Stability of Equilibrium Configuration
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

01:26Equity Theory
Equity theory explains how our sense of fairness influences the dynamics of close relationships. Rooted in social psychology, the theory posits that individuals evaluate fairness by comparing the ratio of their contributions to the rewards they receive. Relationship satisfaction is highest when these ratios are perceived as balanced between partners, promoting mutual reciprocity and a sense of justice.Equity vs. Equality in RelationshipsEquity is distinct from equality. Fairness does not...
