Modern Portfolio Theory – Markowitz Portfolio Selection Model

Markowitz Portfolio Theory Harry Markowitz developed a theory, also known as Modern Portfolio Theory (MPT) according to which we can balance our investment by combining different securities, illustrating how well selected shares portfolio can result in maximum profit with minimum risk. He proved that investors who take a higher risk can also achieve higher profit. The central measure of success or failure is the relative portfolio gain, i.e. gain compared to the selected benchmark. Modern portfolio theory is based on three assumptions about the behavior of investors who: wish to maximize their utility function and who are risk averse, choose their portfolio based on the mean value and return variance, have a single-period time horizon. Markowitz portfolio theory is based on several very important assumptions. Under these assumptions a portfolio is considered to be efficient if no other portfolio offers a higher expected return with the same or lower risk. Continue reading

Social and Commercial Profitability Analysis

Social or National Profitability Public projects like road, railway, bridge and other transport projects, irrigation, projects, power projects, etc for which socioeconomic considerations play a significant part, rather than mere commercial profitability. Such projects are analysis for their net socioeconomic benefits and the profitability analysis of such projects is known as social or national profitability analysis which is nothing but the socioeconomic cost benefit analysis done at the national level.

For instance, some of the inputs may be subsidized. Only the subsidized prices of input is what is relevant for assessing commercial profitability.

Significance of Research

“All progress is born of inquiry. Doubt is often better than overconfidence, for it leads to inquiry, and inquiry leads to invention” is a famous Hudson Maxim in context of which the significance of research can well be understood. Increased amounts of research make progress possible. Research inculcates scientific and inductive thinking and it promotes the development of logical habits of thinking and organization. Research provides the basis for nearly all government policies in our economic system. For instance, government’s budgets rest in part on an analysis of the needs and desires of the people and on the availability of revenues to meet these needs. The cost of needs has to be equated to probable revenues and this is a field where research is most needed. Through research we can devise alternative policies and can as well examine the consequences of each of these alternatives. Decision-making may not be a Continue reading

The Difference Between Agency Theory and Stewardship Theory

Agency Theory   An agency correlation as a contractual set-up under which the business owner or the principal engaged a manager or the agent to execute some service on his behalf and may usually entail some decision making exclusively by the agent. The agency theory revolves on the basic proposition about humans, which deals with principals and agents as self-oriented focusing on exploiting their personal advantage. Agency theory described managers as opportunistic by seizing its optimum advantage for his appointment and role as the mover in the firm for its own benefit, at the expense of the principal. Both parties’ goal is to gain that personal advantage in every way possible with the least outlay and expenditure. These expenditures are defined as agency costs. This is the total of cash outflows made by the principal for its organization be it in budget proportions, auditing, or employee honorariums; the expenses incurred Continue reading

Three Models of Emotional Intelligence

The emotional intelligence field is a very new area of study in psychological research. The definition therefore is varied and is constantly changing. It was only in 1990 that Salovey and Mayer came up with the first published attempt in trying to define the term. They defined emotional intelligence as the ability to monitors one’s own and other feelings and emotions, to discriminate among them and to use this information to guide ones thinking and actions. Emotional intelligence to a larger extent involves “emotional empathy” which is the ability to concentrate on one’s emotions and recognize mood both of themselves and others. It further describes how well one is able to adapt to various life challenges like stress and difficult incidences. It also involves the ability balance “honest expression of emotions against courtesy, consideration and respect”. This would obviously involve possession of some level of good social and communication skills. Continue reading

Globalization and Business Ethics

Business ethics is a well-institutionalized academic field, which deals with the moral dimension of business activity. In the context of international business, it means the treating of moral questions of international cultures and countries. International business should be sensitive to the environment and not just selfish for its own profits. Ethically, safety comes first and the profit comes last. The various issues that ethics target are diverse environmental concerns, animal welfare issues, labor practices, fair trade, health concerns, genetic modification, patenting of genes, cloning etc. International business is both more exposed to a variety of ethical conditions as well as in a position to exploit business ethics due to the sheer size an international company has. The end result of an ethical judgment entails its authenticity from being morally correct. But moral correction itself is a relative concept and is based upon the cultural perceptions as well as traditions. The Continue reading
