Introduction
Introduction
The firm wants to set a contract to maximize the aggregate expectedreturn and is run by a manager.
Although, the manager is self-interested and their will may not agree.
The objective of the firm is to set a contract such that the managerwill do the best maximize the expected return.
We allow the firm make contracts with different seniorities.

Introduction
Literature
Literature has approached issuance of debt by public companies as;
an attempt to reduce taxes;Modigliani and Miller (1993), and Miller (1997)
a signaling device;Hayne Leland and David Pyle (1977) and Stephen Ross (1977)
a way of completing market;Joseph Stiglitz (1974), Franklin Allen and Douglas Gale (1988)
an attempt to raise funds without diluting the value of equity.Stewart Myers and Nicholas Majluf (1984)

Introduction
Financial Structure
Although important, these approaches cannot explain the types ofdebt claims observed in practice.
Nevertheless, in reality, firms issue debt with different seniorities andnonpostponable debts.
The reason is that managers are self-interested in practice but theliterature doesn’t take it account.

Introduction
The role of hard claims is to constraint the managerial excess (EmpireBuilding).
Nonpostponable, short-term1 It forces management to not use money for empire-building investment.2 It triggers liquidation when the assets of the firm are more valuable
elsewhere.
Senior Long-term1 It prevents nonprofitable investment under future earnings.

The Model
The Environment
2 agents: the manager and investor. Both of them are risk neutral.
The interest rate is zero.
3 Periods; t ∈ {0, 1, 2}.The firm is run by a single manager and consists of assets in placeand a new investment opportunity.

The Model The Manager
The Manager
The manager decides whether to take investment opportunity or not.
We want to study cases where the manager wants projects for empirebuilding.
To simplify, we consider that the manager will always take theopportunity if possible.
He never liquidates the firm voluntarily at t = 1. Because this wouldbe a loss of power.
At t = 2, he retires.

The Model The Variables
The variables
All the uncertainty comes from the variables
y1, y2, L, i , r .
They are all revealed at t = 1 and there is symmetric informationthroughout.
The variables are observable but are not verifiable.
The payments made to the security-holders are verifiable and they willbe the basis for the contract.

The Model The Contract
The Contract
The securities can be issued at t = 0 with claims conditional on theamount that is paid out.
We DO NOT allow claims to issued on the return from theinvestment, r , separately from the assets in place, y2. That is, we ruleout project-financing.

The Model The Contract
The Contract
We suppose that both kinds of debt (d1, d2) are senior, in the sensethat any new claims issued by the firm are entitled to payment only ifdate-0 debt-holders have been fully paid off.
It is prohibitively costly to renegotiate with creditors at t = 1.
Thus, if the firm defaults on its short-term debt, in turn, leads toliquidation (L is realized).

Assumption 1
Assumption 1
y1 < i and y2 ≥ L with probability 1.
This assumption says that the manager needs to raise money frommarket to invest and that liquidation is not worth.

The Model The Contract
Proposition 1
Proposition 1
Given Assumption 1, the date-0 market value of the firm is maximized bysetting d1 = 0.
Proof: The firm can face three different total returns:
R1 = y1 + y2 + r − i if y1 + y2 + r − d1 − d2 ≥ i
R2 = y1 + y2 if y1 ≥ d1 or y1 + y2 ≥ d1 + d2
R3 = y1 + L if y1 ≤ d1
Liquidation is undesirable because y2 ≥ L. Thus, to maximize the firmreturn we set d1 = 0 to minimize the event of bankrupt.

Long-term Debt The Firm’s Maximization Problem
The Firm’s Maximization Problem
Denote by F (y1, y2, i , r) the probability distribution at t = 0.
The return from the existing assets,∫
(y1 + y2)dF (y1, y2, i , r) is fixed.
Then, the firm’s maximization problem can be set as
maxd2
∫y1+y2+r−i≥d2(r − i)dF (y1, y2, i , r) (1)

Proposition 2
The first-best cases
1 If r ≥ i with probability 1, then the first-best can be achieved bysetting d2 = 0 (all equity).
2 If r ≤ i with probability 1, then the first-best can be achieved bysetting d2 large enough.
3 If y1 + y2 = y some constant with probability 1, then the first-bestcan be achieved by setting d2 = y .
4 If i and y1 are deterministic, and r ≡ g(y2) where g(·) is a strictlyincreasing function, then the first-best can be achieved by settingd2 = y1 + g−1(i).

Long-term Debt The Firm’s Maximization Problem
First Order Condition
Assuming that F (y1, y2, i , r) is a continuous distribution.
The first order condition of the problem is
E[r − i |y1 + y2 + r − i = d2] = 0. (2)
That is, d2 is set at a level such that the marginal investment projectjust breaks even.
Trade-off of a high d2
Benefit: It helps to stop the manager when the investment is notefficient (i > r).
Cost: Debt overhang. The manager may not invest even if theinvestment is efficient.

Condition C and S.O.C.
Condition C
The left-hand side equation of equation (2),
E[r − i |y1 + y2 + r − i = d2]
is continuously differentiable on an interval [d2, d2]. Moreover, whenever(2) holds, it is also the case that
0 <∂
∂d2E[r − i |y1 + y2 + r − i = d2] < 1 (3)
Denote r − i = X and y1 + y2 = Y . Inequality (3) says thatE[X |X + Y = d2] increases with d2 but less than the amount of d2.

Proposition 3
Proposition 3
Suppose d2 is an optimum debt level.
1 If a dollar is added to every realization of y1, or added to everyrealization of y2 then d2 + 1 is a new optimum debt level.
2 Assume that Condition C holds, and that d2 is an interior optimum in[d2, d2] (in which case it is unique). If a small amount is added toevery realization of i or subtracted from every realization of r , thenthe optimum debt level strictly increases.

(µr , σ

From F.O.C. we have
d2 = y1 + µ2 −σ22σ2r
[µr − i ]
Proposition 3 is OK.
Intuition If the manager’s ability to raise fresh capital at t = 1 isalmost entirely determined by the y1 and y2, then there is little pointin using d2 to screen out the bad new investments.

General Long-Term Security Structure The Security Structure
The General Contract
Now, we explore the possibility that more sophisticated long-term securitystructures than simple debt may be optimal.
The general contract is characterized by two functions (N(P),O(P))where P is the total amount paid to security-holders.
O(P) is the amount that the firm has promised at t = 0 to pay att = 2 to a single class of creditors. 0 ≤ O(P) ≤ P.
N(P) is the amount the manager can keep for new investors at t = 1in the attempt to finance new investment.
N(P) = P − O(P)

Assumption M

For instance, by selling off some fraction of the assets at an artificiallylow price or by hiring extra workers.

The slope of N(·)
(N is increasing) If N(P) is decreasing on P, the manager rises theamount he borrow at t = 1 by lowering the return of the investment.For instance, wasting resources.Thus, if one makes N more flat the investment will occur anyway butwith a higher return because the manager will not waste money.
Slope belongs to [0, 1] If it happens the manager can raise moremoney than he needs to finance the project and save the rest to payback.

Key Lemma
Intuition first the equation K (·):
K (P,N) = E[r − i |y1 + y2 + r − i = P − N and i − y1 = N]
If the project’s profit r − i rises with both the total net profit P − Nand the external financing requirement N, then Condition K will hold.
Also, implies that there is a cutoff value of P, say P∗, such that theexpected value of a marginal date-1 investment is negative(respectively, positive) if P < P∗ (P > P∗).

Proposition 5
Proposition 5
Assume that Assumption F holds. A long-term security structurecomprising simple debt d2 and equity is optimal if:
1 i is deterministic
2 y1 is distributed independently of y2 and r ;
3 E[r |r + y2 = P] is strictly increasing in P, for P ≤ P ≤ P
Intuition: When i is fixed, new investment should not occur for lowvalues of r + y2, since this means low r , on average;
whereas the investment should go ahead for high values of r + y2. Asimple debt/equity security structure implements this quite well.

Proposition 6
Assume that Condition F holds. If
1 r is deterministic,
2 y2 is independent of y1 and i and
3 E[i |i − y1 = N] is strictly increasing in N, for P ≤ N ≤ P
Then it is optimal at t = 0 to issue two classes of debt:
a negligible amount of senior debt, with an option to borrow a finiteamount of additional debt of the same seniority at date 1(d1 u 0,∆d1 > 0);
and a large amount of a second class of debt with no option toborrow any more (d2 =∞,∆d2 = 0).
