Solution:Asymmetric information between managers and investors
Pecking order theory in finance is based on the assertion of Asymmetric information between managers and investors.
Asymmetric information is used to describe a situation between two parties in an economic transaction where one party has more or better information than the other.
Pecking order theory is popularized by Myers & majluf (1984) where they argue that equity is less preferred means to raise capital because when managers (who are assumed to know better about true condition of the firm than investors) issue new equity, investors believe that managers think that the firm is overvalued and managers are taking advantage of this over valuation.
It results investors will place a lower value to the new equity issuance.
