Effect of Technological Improvement on the Average Product of Labor in the Malthusian Model

Population Dynamics in a Pre-Industrial Economy

In an agricultural economy governed by Malthusian principles, the subsistence income is 500 kg of grain per person, and the stable equilibrium population is 1,500 farmers. If a sudden plague reduces the population to 1,000 farmers, what is the most likely dynamic adjustment the economy will undergo?

Stability of Malthusian Equilibrium

In an agricultural economy where the average product of labor decreases as more people work the land, if the population grows beyond the point where average income equals the subsistence level, individual incomes will rise to support the larger population.

Consider an agricultural economy where the average output per farmer depends on the total number of farmers working the land, as shown in the table below. The subsistence level of income, below which the population will decline, is 600 kg of grain per year. Based on this information, what is the stable equilibrium population for this economy?

The Self-Correcting Nature of a Malthusian Economy

An agricultural economy is characterized by a fixed amount of land, and the average income per farmer decreases as the population grows. Imagine this economy's population is currently below its long-run stable equilibrium. Arrange the following events in the logical sequence that describes how this economy will self-correct and return to equilibrium.

In a pre-industrial agricultural economy with a fixed amount of land, the average income per person falls as the population grows. Match each economic state with its corresponding dynamic outcome.

In a Malthusian economy, the fundamental mechanism that drives incomes back down to the subsistence level following a period of population growth is the principle of diminishing ________.
