Capital accumulation, endogenous population growth, and Easterlin cycles
Summary
This study explains population cycles in industrialized economies using a model where birth rates adapt to consumption expectations. Economic and demographic swings arise from balancing present and future consumption.
Area of Science:
- Demoeconomics
- Economic demography
- Population economics
Background:
- Industrialized economies exhibit population cycles.
- Birth rates are influenced by consumption rate discrepancies.
- Easterlin's adapting aspiration level concept is relevant.
Purpose of the Study:
- To model and explain population cycles in industrialized economies.
- To integrate endogenous population growth with neoclassical optimal growth.
- To analyze the impact of consumption expectations on demographic and economic variables.
Main Methods:
- Development of a highly aggregated demo-economic model.
- Incorporation of birth rate dependency on actual vs. expected consumption.
- Analysis of an endogenously growing population system without age structure.
Main Results:
- The model demonstrates the possibility of population cycles.
- Swings in both economic and demographic variables were observed.
- An intertemporal substitution effect was identified as the cause.
Conclusions:
- Endogenous population growth models can explain economic and demographic cycles.
- Consumption expectations play a crucial role in economic and demographic dynamics.
- Intertemporal consumption choices drive observed population cycles.

Energy Budgets and Reproductive Strategies
Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
Population Growth
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...
Growth Models with Integration: Problem Solving
In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...
Exponential Equations with Logarithms: Problem Solving
In ecological studies, exponential models are often used to predict how populations grow over time under favorable conditions. These models assume that the growth rate is proportional to the current population, leading to continuous and compounding increases.The model expresses the population as a function of time, combining the initial population with a growth factor raised to an exponent involving the growth rate and time. To estimate how long it takes for a population to reach a specific...
Exponential Equations for Modeling Growth
Exponential models are essential for describing rapid, multiplicative changes in natural systems, such as population growth. When a population doubles at regular intervals, the process can be modeled using a suitable base. For instance, a bacterial culture that doubles every three hours follows the model n(t)=n0⋅2t/3, where n(t) is the population at the time t.A more general model uses the natural base e, especially for continuous growth. This takes the form n(t)=n0⋅ert, where r is the relative...
Modeling with Differential Equations
Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...
