Background
• 80-90s:
– Lack of investment in public infrastructures
– Declining service quality
– Widespread popular support for reforms, including
privatization and creation of independent regulators
• After 1997:
– Decline in private investments
– Not as much as expected (20% of investments, 10% of
the needs)
– Urban better off than rural
– WB estimates: India might need to invest 8% or more of
GDP over the period 2006–10 to sustain annual GDP
growth at near 8% and replace old capital stocks.
A Map
• Debt as a financing scheme may generate a
virtuous cycle at the micro level
– Capital flows to PPPs if high expected returns
– However, infrastructure projects: LT, demand
uncertainty, political risk, endogenous risk in the
provision of quality
– Debt facilitates the creation of incentives
– Less endogenous risk => higher returns
• Private financing
– Role of decentralization of loans
PPPs
• Literature: costs-benefits of bundling different
phases of infrastructure development (buildingoperation).
• Little attention to the issue of financial
contracting (!)
• Important because
– Form of finance creates distortions that may undo
potential benefits of PPP contracting (micro level)
– Some forms of finance lead to more growth than
others (macro level)
On Some Benefits of PPP
• Consider a road project:
– building and operation phases, investment I.
• The quality of the road:
– high (little need for repairs) or low (many repairs).
• Depends on effort of the builder
– e = 0 (low effort) or e = 0.5 (high effort).
– Probability of low quality is 1 if low effort and 0.5 if
high effort.
– The builder’s cost of effort is C.
• Revenues at the operation stage
– V1 if high quality
– V0 if low quality
Investment Made by the State
• Conventional contracting:
– builder’s contract separated from operator’s contract:
builder does not internalize the externality of his effort
on future revenues: e = 0.
• PPP (bundling) contracting is good:
– builder cares about effect on revenues and will do high
effort when its marginal benefit outweighs its marginal
cost, or when:
0.5 (V1 - V0) ≥ C
Risk Borne by the Private Parties?
• Why shift the risk to private parties?
• Reasons:
– political economy (public accounting rules; “Enronic”
tricks)
– Cost of servicing foreign debt
– Poor fiscal performance
• In terms of efficiency: same total risk has to be
borne?
– Not if differences in access to capital market.
– Not if endogenous risk is present.
PPP Financing
• Consortium consisting of the builder and the
operator (bundling)
• Finance investment of I by equity: keep a share
1 – d of operating revenues, the private investor
gets a share d
• Finance by debt of D : if V1>D >V0, repays
min(D,V0)=V0 if low quality, repays min(D,V1)=D
if high quality.
Debt vs. Equity
Equity

Incentive:
do e = 1
1  d   0.5 V1  V0   C
0.5(V1  D)  C

investment
d  0.5 V1  V0   I
0.5( D  V0 )  I
Same repayment if d (V1  V0 )  D  V0 ,
but then,
V1  D  (1  d )(V1  V0 )
 (1  d )(V1  V0 )
The Form of Financing Matters
• Equity (paying dividends to investors) is not
optimal: a debt contract is better.
• Debt is better for effort incentives: Can give less
to the builder when V0 and therefore more when
V1, for a given expected repayment to the
investors.
• Still, when I is high enough, effort will also be low.
Summing Up
• Private financing of projects generates
additional agency costs, which
undermines the incentive benefits of ‘PPP
bundling’.
• These costs depend on the form of
financial contracting (e.g., equity vs. debt)
– Debt contracting often provides better
incentives to the PPP
Caveat
• Renegotiation
– Renegotiation of payment may be more
difficult with a financial intermediary than the
state
– Renegotiation matters for all forms of
financing
– (soft budget constraint) renegotiation with
state may be discouraged with debt
Some other Possibilities
• Foreign borrowing
– Exposure to exchange risk
– Difficult to service debt since infrastructure is locally
consumed
• Consumer financing (and preferential access)
• State
– Taxation-subsidies (tax holidays: most valuable to
profitable projects!)
– Direct investment (where are PPPs?)
– Guaranteed interest rate
What is Needed for Growth?
• Theories
– Legal system (La Porta et al.)
– Political institutions (Acemoglu-Johnson)
– Financial system (King-Levine, RajanZingales)
A Detour by China (2)
• Poor legal and financial system
• Corrupt and autocratic government
• Large but undeveloped banking system
dominated by four state owned banks.
• Stock market growing fast but still small
w.r.t. banking sector
China, India : counterexamples
• Growth fuelled by private firms
•
(Allen et al. 2005, 2006)
• Main source of financing is “self fundraising”
(even for listed and state firms in China)
• Alternative mechanisms to formal governance
(reputation and trust. Confucius beliefs?)
• A difference in China: Decentralization of loans
to local markets (right to incur debt at local level)
– Local governments supportive and participating
Decentralization
• Facilitate cooperation at the local level to
avoid fragmentation
• Help the bond market liquidity
– reduce transaction costs for secondary
market
– Facilitate transparency
