Explain in details the agency problem
bezimeni [28]

Agency problem

Agency problem also known as agency costs occurs in a two-party relationship (principal/agent) where the agent is expected to act or make decisions for the good of the principal.

For example in a corporate the relationship between the management and shareholders. The management is expected to make decisions that will maximize shareholders interest. The problem arises when the two parties have different interests. In the example above the manager may opt to make his own wealth and not act in the company’s best interest which could be maximizing company’s market value.

Examples of agency relationship in finance

Managers/stockholders

Managers/Creditors

Causes of conflicts between managers and stockholders may include;

Remuneration - low remunerations or fixed salaries despite increased profit margins.

Differences in risk profile- stockholders may prefer high-risk return investments contrary to the managers. When high-risk investment go bad the manager risks job loss

Manipulation of accounting systems- to reflect high profits.

Unnecessary perks management award themselves.

Solution to these problems include threat for firing in case of poor performance, shareholders may also threaten to sell the company, remuneration based on performance, incurring agency costs-these are costs incurred while hiring external auditors, setting a control system, legal costs for employment letters and contracts.

 

Agency problem may be reduced by motivating the manager to act for the companies best interest by offering incentives

Autotrophs that utilize light as their energy source are
k0ka [10]

The correct answer is - phototrophs.

Some of the autotrophs are able to convert the electromagnetic energy from the sunlight into chemical energy in the form of reduced carbon (C). The autotrophs that are able to perform this are called phototrophs. The green plants and the algae are the most prominent members of the phototroph autotrophs.

In essence, the autotrophs are producers, meaning that they are able to produce their own food. The phototrophs are the part of the autotrophs that are able to use the sunlight to produce small amounts of ATP as well as the energy carrier NADHP. By producing the ATP and the NADHP the phototrophs manage to produce glucose, or rather sugars, which are actually their food.
