according to harrod domar model the level of savings remain constant to the proportion of income.
Harrod-Domar model assumes a simple production function y=f(k), where k is capital
Solow is a swann model. Long term economic growth from neoclassical ages are used to compare long term economical complications of present.

"The Solow growth model shows how saving, population growth, and technological progress affect the level of an economy's output and its growth over time" -N. Gregory Mankiw Macroeconomics 6th edition The solow growth model basically shows that an increase in population rate results in a decrease in output (consumption) per person.
In neoclassical theory, savings provide the funds necessary for investment, as they are channeled through financial markets to businesses seeking to invest in capital. This creates a direct link where all savings translate into investment spending, assuming full employment and efficient capital allocation. Conversely, the Keynesian model emphasizes that while savings can lead to investment, they may not always match due to factors like demand fluctuations; thus, savings can sometimes lead to a decrease in overall economic activity if they are not spent. Ultimately, both theories recognize a relationship between savings and investment, but they differ in the mechanisms and conditions under which this relationship holds true.
Endogenous and exogenous growth models differ primarily in the sources of economic growth they emphasize. Endogenous growth models attribute growth to factors within the economy, such as technological innovation and human capital accumulation, suggesting that policy measures can influence these internal factors. In contrast, exogenous growth models view technological progress as an external factor that occurs independently of economic actions and is typically influenced by random events or external conditions. Thus, while endogenous models focus on the role of investment and policy, exogenous models highlight the unpredictability of growth through external influences.

The neoclassical model assumes that individuals are rational, markets are perfectly competitive, resources are scarce, technology is constant, and individuals act to maximize their utility or profit. These assumptions form the foundation of neoclassical economic theory.

The principle of revealed preference focuses on observing consumers' choices to infer their preferences, suggesting that what people choose reveals their true preferences, regardless of their utility functions. In contrast, neoclassical consumer theory employs a broader approach that incorporates utility maximization, indifference curves, and budget constraints to model consumer behavior. While revealed preference relies solely on actual choices made in the marketplace, neoclassical theory also considers hypothetical scenarios and the underlying utility structure to explain consumer decision-making. Thus, revealed preference offers a more empirical perspective, whereas neoclassical theory is more theoretical and analytical.
Logistic Model
It means that the theory could be right and the model shows you dimenstionaly.
The constant growth valuation model assumes that a stock's dividend is going to grow at a constant rate. Stocks that can be used for this model are established companies that tend to model growth parallel to the economy.
The modern atomic model is based on quantum mechanics.

An exponential model has a j-shaped growth rate that increases dramatically over a period of time with unlimited resources. A logistic model of population growth has a s-shaped curve with limited resources leading to a slow growth rate.
