It assumes that savings and investment are all that is needed for growth. No diminishing returns to capital is an implicit assumption.

Why is the harrod-domar growth model not widely used these days?
The reason why it is not formally taught as a viable growth model is due to its inherent weaknesses. The weaknesses lie in the assumptions of the model. When creating an economic theory, you can make any assumptions you want, regardless of how unrealistic they may be. If the model starts to fall apart when you rest the weakest assumptions, it loses credibility.One problem with the model is that the price for labor and capital (wage rate and interest rate) are fixed. Along with this assumption, the model assumes that each input is used in equal proportions. In reality we know that these assumptions don't hold.Another problem with the model is that is assumes investors (savers) are only influenced by changes in output. The greater the output, the more investors will invest capital which in turn increases output. This is known as the accelerator principle and it does not hold up in empirical studies. Investors are influenced by the amount of risk they must take given the expected rate of return they will receive on their investment.A model that rests the assumptions of the H-D model is the Solow Model (aka Solow-Swan Model). It uses some of H-D framework but then expands on it to allow for flexibility in the use of both capital and labor as flexible inputs to output. A great source for a more detailed but easy to understand explanation is Wikipedia. Check out the related link. After reading this, review the commentary on the Solow Model. Hope this help.
What is the main difference between Harrod-Domar growth model and Robert Solow growth model?
difference between horred-domer and solow model
Society's production possibilities frontier is based on?
simplifying assumptions, but is still useful for illustrating scarcity, opportunity cost, and economic growth.
What is the Solow growth model?
"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.
How does the Harrod-Domar growth model differ from the Neo-classical growth mode?
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

A model of population growth that assumes that finite resource levels limit population growth?
Logistic Model
What is ansoff model?
It is a strategic growth option model.
Constant growth valuation model for stock?
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.
How can you make theoretical probability more accurate?
By ensuring your model is as good as it can be. Make sure that any assumptions that you make for your model are justified and, if necessary, properly reflected in the model.
Is arithmetic growth a slow or rapid growth model?
slow
Compare the exponential model and the logistic model of population growth. (?
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.
What is the main difference between Harrod-Domar growth model and Robert Solow growth model?
difference between horred-domer and solow model
The exponential model of population growth applies?
The exponential model of population growth describes the idea that population growth expands rapidly rather than in a linear fashion, such as human reproduction. Cellular reproduction fits the exponential model of population growth.
In the exponential model of population growth the growth rate?
remains constant
Society's production possibilities frontier is based on?
simplifying assumptions, but is still useful for illustrating scarcity, opportunity cost, and economic growth.
Which of the seven step problem solving model includes facts assumptions and opinions?
