Let N(t) N ( t) be the number of individuals in a population at time t t, and let b b and d d be the average per capita birth rate and death rate, respectively. In a short time Δt Δ t, the number of births in the population is bΔtN b Δ t N, and the number of deaths is dΔtN d Δ t N.

develops a model of long-term growth which combines Malthus's views on effective demand and diminishing returns with his principle of population. One of the most interesting aspects of this model is its explanation of unemployment as a permanent phenomenon and not merely a transitory phase.

As a description of population-income interactions, the Malthusian model had a long period of success, covering most of human history in most of the world until the beginning of the industrial revolution. In this paper we ask whether the model has any relevance to the world today.
