A theory states that while investors and borrowers may normally concentrate on a particular natural maturity market, conditions may cause them to change maturity markets. This theory is called the:

Preferred habitat theory.

Explanation:

Explanation on this theory deals a lot on yield; as it tries to let us know that the said investors who's bond are put to play here always tend to show that they are willing to make purchases out of their line or circle of limit if a reasonable amount of yield/ high yield is attached or falls back with their bond when they make these transactions.

This directly implies that investors interest are always seen to be embedded on their returns and also maturity. It is seen to also affect the yield curve in many cases.

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
