An agrarian society with a fixed amount of land experiences a major technological breakthrough, such as the invention of a new plow, which doubles the amount of grain that can be harvested per worker. According to an economic model where any income above the minimum required for survival leads to population growth, this innovation will result in a new long-term stable state where the average income per person is permanently higher than it was before the innovation.

An agrarian economy has a stable population where the average income is just enough for subsistence. A new irrigation system is introduced, which significantly increases the amount of food each farmer can produce. Assuming that any income surplus leads to population growth and that adding more farmers to the fixed amount of land leads to smaller and smaller gains in total output, what is the most likely long-run outcome?
An agrarian economy, initially in a stable state where income is at the subsistence level, experiences a significant technological advancement that boosts agricultural productivity. Arrange the following events to show the correct sequence of the economy's transition to a new long-run stable state.
An economic theory posits that the essential, defining characteristic of a particular economic system is a continuous process where new innovations displace old technologies and firms, driving progress. A government, however, proposes a policy to provide large, long-term subsidies to established automobile manufacturers to protect them from new electric vehicle startups. According to the economic theory described, what is the most likely long-term outcome of this policy?

An agrarian society with a fixed amount of land experiences a major technological breakthrough, such as the invention of a new plow, which doubles the amount of grain that can be harvested per worker. According to an economic model where any income above the minimum required for survival leads to population growth, this innovation will result in a new long-term stable state where the average income per person is permanently higher than it was before the innovation.
An agrarian economy with a fixed amount of land is in a long-run stable state with a population of 1,000 farmers, where the average income is 400 kg of grain per person, the minimum required for subsistence. A new, more resilient crop is introduced, changing the relationship between labor and output as shown in the table below.
Number of Farmers Total Grain Output (kg) 1,000 500,000 1,250 562,500 1,500 600,000 1,750 612,500 Assuming that any income above the subsistence level leads to population growth, what will be the new stable population in the long run?
Comparing Shocks in a Pre-Industrial Economy
Consider an economy where the average product of labor depends on the population size, and the population grows whenever income is above the subsistence level. The economy is initially in a stable state at point A, where the average product of labor is just enough for subsistence. A technological improvement shifts the entire average product of labor curve upwards. Point B represents the new, higher average product at the original population size. Point C represents a new stable state on the higher curve, where the average product has returned to the subsistence level but at a larger population. Which statement best describes the economy's adjustment path to the new long-run stable state following the technological improvement?
