Where we come from and where we try to go
Asonuma & Trebesh (2016): The way to restructure debt matters for its growth effects
Balteanu & Erce (2011): Sovereign defaults can trigger bank crises and exacerbate the
default costs
In this project we cross these two ideas and ask ourselves:
1. What are the channels through which debt restructuring affect GDP?
2. Are those channels affected by the restructuring strategies?
Short answers:
1. Both direct and indirect effects through the financial sector
 Financial crises trigger decline in bank credit to private sector
 Decline on investment follows, feeding into growth
2. Yes, the strength of these channels depends on the debt restructuring strategy
 Accumulating arrears is not the right plan if your idea is to bring growth back
 If a hard default is unavoidable: restructure fast and don’t be harsh

New Stylized Facts
9

10.
Stylized Fact(s) #1
GDP and investment decline substantially in post-default DRs, less severely in weakly
preemptive ones, and are unaffected in strictly preemptive cases
Private credit falls and lending rates hike sharply during post-default DRs, while no
such effect is found for strictly pre-emptive cases
Capital flows remain low after any DR, but recover fast after strictly pre-emptive cases
10

11.
Stylized Fact #2
GDP and Investment co-move more strongly in DRs that in normal times
Dep. Var. = GDP growth rate
*** Significant at 1% level. Robust standard errors, clustered at country-level, in parenthesis
 Output and investment co-move, most strongly in DR, when both tank together
 This “excess” co-movement around DR appears strongest in pre-emptive cases
 What available theories explain this?

Local projections
As in Jorda & Taylor (2012), we estimate models of the following type:
𝑔𝑐,𝑡+ℎ=𝛼ℎ
𝑐
+ 𝐷𝑅 𝑐,𝑡 ∙ 𝛾 ℎ +𝑋𝑐,𝑡−1 ∙ 𝛽ℎ
−1
+ 𝑋𝑐,𝑡−2 ∙ 𝛽ℎ
−2
+ 𝜀 𝑐,𝑡+ℎ
 Subscripts c and t indicate country and year, respectively.
 h indicate horizon and we estimate from h = 0 up to h = 9.
 𝑔𝑐,𝑡+ℎ = 100 ∙ (𝐺𝐷𝑃𝑐,𝑡+ℎ-𝐺𝐷𝑃𝑐,𝑡−1)/𝐺𝐷𝑃𝑐,𝑡−1 is the cumulative GDP growth rate
from time t -1 to t + h in country c.
 𝛼ℎ
𝑐 are country-fixed effects.
 𝐷𝑅 𝑐,𝑡 is our debt restructuring indicator (in country c in year t).
 𝑋𝑐,𝑡 is a vector of control variables - lagged dependent variables, cyclical
component of GDP per capita, openness, and log of population.
 𝜀 𝑐,𝑡+ℎ denotes the error term.

Selection & endogeneity
20

21.
Endogeneity
Debt restructurings are not exogenous - policy makers’ decision
Define country i output at time t as 𝑌𝑡,𝑖. Our OLS estimates deliver
𝐸 𝑌𝑖,𝑡+ℎ 𝐷𝑖,𝑡 = 1 − 𝐸 𝑌𝑖,𝑡+ℎ 𝐷𝑖,𝑡 = 0
But, as shown by Angrist and Psichke (2008), this difference has two components:
– 𝐸 𝑌𝑖,𝑡+ℎ 𝐷𝑖,𝑡 = 1 - 𝐸 𝑌𝑖,𝑡 𝐷𝑖,𝑡 = 1  Average Treatment Effect (ATE)
– 𝐸 𝑌𝑖,𝑡 𝐷𝑖,𝑡 = 1 - 𝐸 𝑌𝑖,𝑡 𝐷𝑖,𝑡 = 0  Selection Bias
OLS might be biased and simply capture other features of countries undergoing DRs:
 Higher public debt-to-GDP ratio
 Lower private credit-to-GDP ratio
 Lower country’s credit ratings
…
21

22.
AIPW: Treatment Models and Selection Bias
One way to get around this selection bias is to model DRs as policy treatments and
use treatment effects models (Jorda et al. 15, 16) to rid of the selection bias.
We follow Jorda et al. (15, 16) and complement our local projections with an
Augmented Inverse Probability Weighted estimator (hereafter AIPW)
– Assess the extent to which treated and non treated units are different
– Estimate the likelihood of being treated (propensity score) and use it to
weight the observations when performing the OLS estimation
22

23.
Endogeneity – prior characteristics
Characteristics of the Treatment and Control Groups
Asses differences between treatment (start of DR) and control groups (other observations), by
regressing each variable on the DR dummies and using the constant as normal times value.
Regressions include country FE.
These results show that countries indeed have different characteristics prior to any type of
restructurings, raising an issue of endogeneity

Augmented Inverse Probability Weighted Estimator (AIPW)
Estimation steps:
 1st stage:
o Estimate discrete-variable model: 𝑃 𝐷𝑅 𝑐,𝑡 = Φ(𝑍 𝑐,𝑡, . ), where 𝑍 𝑐,𝑡 includes
public debt, private credit, rating, and 2nd stage regressors
o Calculate weights based on propensity scores: ipw 𝑐,𝑡 =
𝜙(𝑍 𝑐,𝑡)
Φ(𝑍 𝑐,𝑡)
−
1−𝜙(𝑍 𝑐,𝑡)
1−Φ(𝑍 𝑐,𝑡)
 2nd stage:
o Use ipw 𝑐,𝑡 as weights on the Local Projections to obtain ATE
One (big?) issue - # endogenous variables (restructuring strategies) >1
 How do we define the 1st stage?
o Treat all types of debt restructuring as having identical drivers?
o Three different dependent variables? Use binomial or multinomial models?
 Currently, we use a binomial, independent, model for each DR strategy

Figures show the area under the ROC curve. ROC area takes values between 0.50 and 1. A
value of 0.50 indicates that regressors have no ability to classify observations.
The ROC curve is greater than 0.50 (Schularick & Taylor 2012 argue a curve above 0.70 is
sufficient) for all types of DRs (0.81, 0.91, and 0.80, respectively).

DR strategies – other aspects
(Preliminary)
38

39.
Other aspects of restructuring strategies: Haircuts (TZ, 2014)
As Trebesch and Zabel (2014), divide post-default events based on whether haircut is
above or below median
Figures show local projections of 100 ∙ (𝐺𝐷𝑃𝑐,𝑡+ℎ-𝐺𝐷𝑃𝑐,𝑡−1)/𝐺𝐷𝑃𝑐,𝑡−1 for h = 0, 1, …, 9, where h
indicates horizon. Solid lines are point estimates. Gray bands are 95% confidence intervals.
Policy implication:
Sovereigns can minimize output costs of hard default if they minimize the losses
imposed on creditors
39

40.
Other aspects of restructuring strategies: Duration
Divide post-default events based on the duration the debt restructuring
Figures show local projections of 100 ∙ (𝐺𝐷𝑃𝑐,𝑡+ℎ-𝐺𝐷𝑃𝑐,𝑡−1)/𝐺𝐷𝑃𝑐,𝑡−1 for h = 0, 1, …, 9, where h indicates
horizon. Solid lines are point estimates. Gray bands are 95% confidence intervals.
Policy implication:
Sovereigns could minimize output losses from hard default by settling (reaching a
restructuring agreement) with creditors as fast as possible
40

41.
Wrapping up
We add to the empirical literature on the costs of sovereign debt restructuring
Main findings
 New stylized facts on GDP growth, investment and banking sector costs of DR
 Show that a self-reinforcing credit/investment/growth effect, helps understanding the
output costs of DR
 The strength of these effects depends on the restructuring approach
 Post-default DRs imply worse output loss and stronger investment-credit effect
• Post-default :
=> 5%-peak GDP decline, lasting 5+ years. Bank crisis
• Weakly/strictly preemptive:
=> 3%-peak GDP decline, short-lived. No bank crisis
 Even more so if:
 Haircut imposed is large (Trebesch & Zabel 14) or negotiations lasts long

Banking Crisis Dataset
Laeven and Valencia (2013) define a banking crisis as an event that meets:
1) Significant signs of financial distress in the banking system (as indicated
by bank runs and large losses);
2) Significant policy measures in response to the losses in the banking system.
At least 3 out of the following 6 measures have been used:
i. Deposit freezes and/or bank holidays;
ii. Significant bank nationalizations;
iii. Bank restructuring gross costs (at least 3% of GDP);
iv. Large liquidity support (5% of deposits and liabilities to foreigners)
v. Significant guarantees put in place
vi. Significant asset purchases (at least 5% of GDP);

OLS estimation: Lending Interest Rate
Lending Interest Rate after Sovereign Debt Restructuring
Figures show local projections of 100 ∙ (𝑖 𝑡+ℎ − 𝑖 𝑡−1)/𝑖 𝑡−1 for h = 0, 1, …, 9, where h indicates horizon.
Solid lines are point estimates. Gray bands are 95% confidence intervals.

Endogeneity – sample selection
Figure: Kernel Density- Predicted Probabilities of Debt Restructuring
 Treatment group = observations with debt restructuring
 Control group = observations without debt restructuring

Endogeneity…
APIW is close to state-of-art to tackle selection biases due to observables…
…but unobservables may still generate endogeneity…
Any IV strategy in the room?!

Backup Slide 1: AIPW estimator
• Estimation steps:
 Step 1: Estimate the Probit model:
o takes unity for debt restructuring events
o is a vector including public debt-to-GDP ratio, private credit-to-GDP ration,
credit rating, # of past debt restructurings, and 2nd stage regressors
 Step 2: Estimate the following equation:
o is the cumulative GDP growth rate.
o , and are post-default, weakly preemptive, and strictly preemptive
debt restructuring dummies, respectively.
 Step 3: Obtain the predicted value from the regression in Step 2.
 Step 4: Use and , find the average treatment effect:
for Type = {Post, Weak, and Strict}. 49
