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.
Difference between harrod-domar model of economic growth?
The Harrod-Domar model of economic growth emphasizes the relationship between investment, savings, and economic output, suggesting that a certain level of investment is necessary to achieve a specific growth rate. It posits that an increase in investment leads to an increase in income and output, with the growth rate dependent on the capital-output ratio and the savings rate. The model highlights the importance of maintaining a balance between savings and investment to ensure stable economic growth. However, it has been criticized for its simplistic assumptions and neglect of factors like technology and labor.

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.

What are the assumptions of the neoclassical model?
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.
Why is Socrates a role model?
Socrates is considered a role model because of his commitment to seeking truth and questioning assumptions, his willingness to engage in open dialogue and debate, and his emphasis on self-examination and self-improvement. His philosophical method of questioning and reflection continues to inspire critical thinking and intellectual growth.
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.
A model of population growth that assumes that finite resource levels limit population growth?
Logistic 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.
What are the underlying basic assumptions?
The underlying basic assumptions refer to the foundational beliefs or premises that form the basis of a concept, theory, or model. These assumptions are often implicit and shape the way in which information is interpreted or analyzed within a particular framework. Clarifying these basic assumptions is important for understanding the underlying logic and limitations of a given perspective.
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.
