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.
It assumes that savings and investment are all that is needed for growth. No diminishing returns to capital is an implicit assumption.
According to the classical economists there is full employment in the economy, every job seeker gets the job in accordance with his capabilities and there is never involuntary unemployment. Moreover, the resources of the economy are fully employed. The classical economists believed in Lassies fair economy, there should be no government intervention in the economic affairs. In other world, the classical believed in the free enterprise economy. It is told that the classical economists never presented their model in a refined form. However, the credit goes to modern economists who integrated classical form. However, the credit goes to modern economists who integrated classical ideas. The classical model has two pillars. They are Says law of market and quantity theory of money. The say's law is concerned with the real sector or production sector of the economy. While quantity theory is linked with the classical views regarding labor market and credit are also presented. All such means the classical model is explained with the help of four markets of the economy: Goods market, credit market, labor market and money market. A closed private economy where there is no foreign trade and no government, Short run model where population, capital, technology and organizational knowledge remain the same. Anonymous
Decision Making is a basic function of manager, economics is a valuable guide to the manager. There are basically two major models of decision-making - the classical model and the administrative model. The classical model of decision making is a prescriptive approach that outlines how managers should make decision. Also called the rational model, the classical model is based on economic assumptions and asserts that managers are logical, rational individuals who make decision that are in the best interest of the organization. The Administrative model of decision making is a descriptive approach that outlines how managers actually do make decisions. Also called the organizational, neoclassical, or behavioral model, the administrative model is based on the work of economist Herbert A.

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.

The gradualism model assumes that change happens slowly and continuously over time, that small changes accumulate to produce larger changes, and that there is no clear distinction between different species or stages of evolution.
