Equilibrium in the Malthusian Model
Malthus's core argument is that an economy will naturally self-correct towards a stable equilibrium. This state is characterized by the population size and income level at which the average income is equal to the subsistence level. This equilibrium is self-perpetuating, meaning that once reached, there is no internal tendency for change unless an external force—a factor determined outside the model—disturbs the conditions.

Consider a local market for corn where the price has remained at $3 per bushel for several months. At this price, the total quantity of corn that farmers bring to the market each week is consistently purchased by consumers, with no surplus or shortage. Which statement best analyzes why this situation represents an economic equilibrium?
Analyzing Market Stability
A government introduces a temporary subsidy on electric cars for one year, causing the price for consumers to drop and sales to remain consistently high for that year. Because the market situation is stable throughout the year, it can be described as being in an economic equilibrium.
Defining Economic Equilibrium
A city's rental market is in a stable state, with rents and vacancy rates remaining constant for the past two years. Suddenly, a major local employer announces it is shutting down, leading to a large number of residents moving away. Which of the following statements best analyzes this situation according to the concept of a self-perpetuating economic model?

Match each term with the market scenario that best illustrates it.
Consider a market for a newly released video game. The initial price is set very high, resulting in a large number of unsold copies (a surplus). In response, retailers begin to systematically lower the price. As the price falls, the number of games sold each week increases, and the surplus begins to shrink. Which statement best analyzes the state of this market during the period when prices are being lowered?
A stable market condition that persists without any internal tendency for change is known as an economic equilibrium. This state will only change if acted upon by a(n) ____ force.

Malthusian Equilibrium and Population Dynamics
In an agricultural economy with a fixed amount of land, the average output of food per person is currently higher than the minimum amount required for the population to sustain itself. According to the internal logic of this economic model, what is the most likely long-run outcome?
State of a Pre-Industrial Economy
Significance of the Malthusian Equilibrium Point
In a pre-industrial agricultural economy with a fixed amount of land, if the current population size is smaller than the level at which the average product of labor equals the subsistence income, the population will tend to decrease over time.
The Inevitability of Subsistence in a Malthusian Economy
In a model of a pre-industrial agricultural economy with a fixed amount of land, match each economic state or concept with its corresponding description.
Consider a pre-industrial agricultural economy with a fixed amount of land, operating in a stable state where the population size is constant and income per person is just enough for survival. If a permanent natural disaster renders a significant portion of the farmland unusable, what will be the new long-run stable state for this economy, assuming the fundamental principles of the economic model hold true?
In a pre-industrial agricultural economy with a fixed amount of land, the minimum income required for survival is 400 kg of grain per person per year. When the population is 1,000, the average output is 600 kg per person. When the population is 1,500, the average output is 400 kg per person. When the population is 2,000, the average output is 300 kg per person. In the long-run stable state, the population of this economy will be ____.
An agricultural economy with a fixed amount of land is in a long-run stable state. A one-time technological innovation suddenly increases the amount of food that can be produced per person. Arrange the following events in the logical sequence that describes how the economy returns to a new long-run stable state according to the model's internal dynamics.
