5. Verifiable Income Flashcards

1
Q

What makes a variable verifiable?

A

A court of law are able to enforce the execution of the contract agreement. So third parties can also verify terms written in the contract

Q

How is income modelled in the principal agent model Innes (1990)?

A

Random variable R distributed on the interval (0, R bar) according to the distribution p(R|e) where e>0 denotes the entrepreneurs effort

Q

How is the contract modelled in the principal agent model Innes (1990)?

A

W(R) is the entrepreneurs reward when realised income is R; R-w(R) is lenders reward

Q

What is incentive compatibility constraint?

A

This is obtained after setting the derivative of the objective function wrt e equal to 0

Integral of w(R)dp(R|e)/de dR = g’(e)

Q

What is the monotonicity constraint?

A

It requires that the lender’s payoff is nondecreasing in the projects return.

R-w(R) is nondecreasing for all R

Q

Suppose mu >0, what does the monotone likelihood property imply?

A

That there exists a threshold income R* such that

W(R) = R if R>R*
W(R) = 0 if R<R*

Q

Proposition 1 live or die contract

A

The solution generalises the maximal insider incentive principle: the borrower receives nothing for R<R* and the entire income for R>R*. These type of contracts are called live or die

16
Q

What happens if we relax the lenders limited liability constraint

A

The solution would degenerate with W(R)=0 for R<R bar and spike at R bar

17
Q

Proposition 2 when is the optimal reimbursement the standard debt contract?

A

When we add the monotonic constraint the optimal reimbursement is the standard debt contract. When monotonicity is imposed the lenders limited liability constraint isn’t binding

18
Q

For a risk averse entrepreneur why is there a conflict in contract design?

A

Conflict between insuring the entrepreneur against income uncertainty and inducing effort

19
Q

What reward does the borrower get?

20
Q

What reward does the lender get?

21
Q

What is the assumption of monotonic reimbursement and why is it needed?

A

R-w(R) is nondecreasing for all R. Otherwise the entrepreneur could borrow R2-R1 from a third party and increase her reward by w(R2)-w(R1) and then repay the third party and make a profit

22
Q

If we impose the extra constraint that the lender has limited liability w(R)<=R then what is the solution?

A

W(R) = R if 1+ mu((dp(R|e)/de)/p(R|e)> lambda
W(R)= 0 if 1+ mu((dp(R|e)/de)/p(R|e) < lambda

23
Q

If mu=0 what is the optimal effort given by?

A

g’(e)= integral of Rdp(R|e)/de dR

24
Q

What is the correspondence between the fixed investment model and the verifiable income model?

A

The only differences are:
-In fixed investment there are only two states and in the verifiable income model there are a continuum of state.
-In fixed investment there is a benefit to working and in verifiable income there is a cost of working

25
Does the fixed investment model satisfy the monotone likelihood property?
Yes because Ph is bigger than Pl and Ph indicates a higher level of effort
26
What is the correspondence between the incentive compatibility constraints of the fixed investment model and the verifiable income model?
They are very similar. In each case increasing effort increases likelihood of higher reward but also increases costs of effort
27
What is the optimal capital structure when mu=0
Mu is the multiplier associated with the incentive compatibility constraint. The project is so good that no incentives are needed for you to put in effort
28
Would a risk averse borrower prefer to obtain funds through an equity or a debt contract?
Equity contract
