2. Motivation
Figure: 5 year CDS premia
Four banking groups account for around 80% of loans to UK ļ¬rms.
The crisis had a heterogeneous impact on these banking groups.
3. Contribution
Exploit an exogenous source of credit constraints faced by UK ļ¬rms,
induced by banking relationships they maintained prior to crisis.
Use natural experiment approach to assess whether the exit margin of
ļ¬rms was distorted by credit constraints following the crisis.
4. Main Messages
Maintaining relationships with Distressed Banks increased the
probability of ļ¬rms exiting.
Increased probability of exiting was not concentrated in the most
unproductive ļ¬rms.
I Tight credit may have limited the cleansing impact of the recession.
I While micro impact is signiļ¬cant, macro impact is limited.
5. Related Literature: Credit Constraints and Firm Activity
Global ļ¬nancial crisis provides a natural experiment for studying the
impact of tight credit conditions on ļ¬rm activity.
Oļ¬ers a solution to disentangling credit demand and credit supply.
Tighter credit conditions following the crisis adversely aļ¬ected ļ¬rm
investment and ļ¬rm employment (e.g. Duchin et al. (2010) and
Bentolila et al. (2013)).
6. Related Literature: Credit Constraints and Firm Dynamics
Contrasting views on how recessions and crises aļ¬ect the process of
ļ¬rm entry and ļ¬rm exit.
āCleansingā view: recession accelerates the exit of ineļ¬cient ļ¬rms
which are insulated during boom times. (e.g. Schumpeter (1934);
Caballero and Hammour (1994)).
āSullyingā / āScarringā view: frictions associated with recessions may
adversely aļ¬ect productivity (Barlevy (2002, 2003); Ouyang (2009);
Osotimehin and PappadĆ (2016)).
7. Productivity Distortions from Banking Crises
Firms that need external credit to survive may be more productive
(e.g. Barlevy (2003)).
Less productive ļ¬rms which are less reliant on bank ļ¬nance face
reduced competition.
Forbearance/ āzombie lendingā (e.g. Peek and Rosengren (2005);
Arrowsmith et al. (2013); Roland (2016)).

10. Related Literature: Credit Constraints and Firm Dynamics
Recent empirical studies have found some support for the view that
credit constraints can weaken the ācleansingā eļ¬ect of recessions.
Evidence that the negative relationship between ļ¬rm productivity and
the probability of exit weakened following the Great Recession (e.g.
Foster et al. (2016); Harris and Moļ¬at (2016)).
Some highly productive, credit constrained ļ¬rms are forced to exit
(e.g. Eslava et al. (2010); Hallward-Driemeier and Rijkers (2013)).
11. Distressed and Non Distressed Banks
Follow the approach of Bentolila et al. (2013):
I Deļ¬ne Distressed Banks as those which obtained state funding between
2008 and 2009 or required a takeover.
I Deļ¬ne NonDistressed Banks as those which did not receive state
funding and did not require a takeover.
I Divide ļ¬rms into Treatment and Control groups based on which banks
they had relationships with in 2008.
12. Identiļ¬cation: Distressed and Non Distressed Banks
For identiļ¬cation, require that
I i) Credit supply conditions tightened by more for ļ¬rms which had
pre-crisis relationships with Distressed Banks.
I ii) Firms subject to a tightening of credit conditions cannot easily
switch bank.
13. Identiļ¬cation: Distressed and Non Distressed Banks
i) Credit supply conditions tightened by more for ļ¬rms which had
pre-crisis relationships with Distressed Banks.
I CDS premiums of banks similar prior to crisis, but diļ¬erent following
crisis. Increase in CDS spreads particularly pronounced for RBS and
LBG.
I Little evidence that lending commitments made by Distressed Banks in
return for public support inļ¬uenced their lending behaviour.
I Overall, evidence suggests the contraction in credit supply by
Distressed Banks was greater than that of NonDistressed Banks.
14. Identiļ¬cation: Distressed and Non Distressed Banks
ii) Firms cannot easily switch bank.
I Asymmetric information makes switching diļ¬cult.
I Bank switching by UK ļ¬rms is low, with no pick-up following crisis.
Figure: Evolution of Switching Rates Over Time
16. Data: Corporate Banking Relationships
Lenders commonly require companies to provide security against a
loan, in the form of a mortgage, a ļ¬oating charge or a ļ¬xed charge.
In the UK, registered companies are required to report charges and
mortgages to Companies House within 21 days of their creation date.
We identify ļ¬rm-bank relationships using a textual algorithm.
17. Empirical Speciļ¬cation
Baseline speciļ¬cation- Linear probability model.
How does having a relationship with a Distressed Bank at time t aļ¬ect
the likelihood of exit in the subsequent period for ļ¬rm i in industry j:
Yi,t = gj, +Xi,tk +b1 ā„Distressed Banki,t +b2 ā„Post Crisist (1)
+b3 ā„Distressed Banki,t ā„Post Crisist +ei,t
where
Yi,t is an indicator variable equal to 1 if ļ¬rm i subsequently
exits in the speciļ¬ed time frame and 0 otherwise

20. Results: Baseline speciļ¬cation
Change in probability of exit signiļ¬cantly higher for ļ¬rms with
Distressed Banks following the crisis than ļ¬rms attached to
NonDistressed Banks.
Change in the probability of exit within 2 years was around 0.6
percentage points higher for ļ¬rms which had a relationship with
Distressed Banks relative to ļ¬rms with NonDistressed Banks.
21. Exit Dynamics and Productivity
Consider a smaller sample of ļ¬rms for which we are able to calculate a
proxy for their gross value added productivity:
Productivityi,t =
GVAi,t
Employees
where
GVAi,t is a proxy of gross value added in real terms given by
the sum of a ļ¬rmās reported Operating Proļ¬ts and the
Cost Of Employees, deļ¬ated by industry deļ¬ators.
22. Exit Dynamics and Productivity
Split the observations into productivity quintiles, based on proxy for
gross value added productivity.

banked with āNon-Distressedā banks

23. Exit Dynamics and Productivity

26. Robustness: Placebo Crises
DiD speciļ¬cation relies on the assumption of parallel pre-crisis trends.
Undertake placebo tests considering alternative placebo ācrisesā.
Consider the impact of having relationships with Distressed Banks on
the two year exit probability for two placebo ācrisesā: 2004 and 2006.

28. Robustness: Weighted Regression
Productivity sample limited to ļ¬rms which report Operating Proļ¬ts,
Employees and Cost Of Employees.
Under-represents smaller ļ¬rms.
Weight observations in productivity sample to match the number of
ļ¬rms in each industry-size-bank group-year cell in baseline sample.
30. Robustness: Alternative Measure of Productivity
Productivity sample limited to ļ¬rms which report Operating Proļ¬ts,
Employees and Cost Of Employees.
Use an alternative measure of productivity, given by the ratio of GVA
to the cost of employees, following Giordano et al. (2015).
Productivity_ai,t =
GVAi,t
Cost Of Employees
32. Conclusion
Exploit pre-crisis banking relationships as an exogenous source of
credit constraints faced by UK ļ¬rms.
Credit constraints faced by UK ļ¬rms following the ļ¬nancial crisis had
a detrimental impact on their probability of survival.
Credit constraints distorted productivity distribution of exiters.
Some credit constrained ļ¬rms may have been forced to exit their
industry, despite being more productive than surviving competitors.
While micro impact is signiļ¬cant, macro impact is limited.
33. Model: Overview
Closed economy Melitz (2003) model with credit constraints, aāla
Manova (2013).
Firms must ļ¬nance a fraction of their ļ¬xed costs upfront, using
ļ¬nancial intermediaries.
Fraction of ļ¬xed cost to be ļ¬nanced varies across ļ¬rms.
Credit market frictions raise the productivity threshold for ļ¬rms.
Firms more dependent on external ļ¬nance are more adversely aļ¬ected
by credit market frictions.
34. Model: Consumers
Constant elasticity of substitution (CES) preferences over a continuum
of goods indexed by w over ā¦:
U =
ā„R
w2ā¦ q(w)rdw
ā¤1
r
where s = 1
1 r > 1
With optimal consumption and expenditure for diļ¬erent varieties given
by:
q(w) = Q
h
p(w)
P
i s
r(w) = p(w)q(w) = R

35. Model: Producers
Continuum of ļ¬rms, each of which produces a variety w.
Entrants are required to pay an entry cost, fe, draw productivity level,
j , from g(j)
Labour consists of a ļ¬xed cost f and a variable cost which depends on
a ļ¬rmās productivity, j :
l = q
j +f
36. Model: Producers
Firms have to pay a fraction, di of ļ¬xed cost, f , upfront.
Fraction low, dL , with probability c or high, dH , with probability
1 c .
Upfront ļ¬xed cost ļ¬nanced by a ļ¬nancial intermediary.
Financial contract: at start of period, ļ¬rms oļ¬er repayment F to be
paid at the end of the period
Intermediaries obtain agreed repayment F with probability l ļ£æ 1.
With probability 1 l , ļ¬rm defaults and the intermediary does not
receive F, but seizes collateral tfe. from the ļ¬rm.
In the case of default, the ļ¬rm replaces its collateral, tfe.
37. Model: Producers
Upon entry, the problem of the ļ¬rm is to choose its price, quantity
and repayment to maximise proļ¬ts subject to three constraints:
max
p(j),q(j),F(j,di )
p(j)q(j)
h
q(j)
j +(1 di )f +lF(j,di )+(1 l)tfe
i

(1) q(j) = Q

P
i s
(2) F(j,di ) ļ£æ p(j)q(j) q(j)
j (1 di )f
(3) di f ļ£æ lF(j,di )+(1 l)tfe
Assume constraint (3) binds with equality.
Deļ¬ne a productivity threshold, jā¤
di
, below which producers choose
not to produce.
38. Model: Comparative Statics
Solve the model to ļ¬nd the two productivity thresholds, jā¤
dL
and jā¤
dH
.
To illustrate comparative statics, calibrate the model, closely following
Melitz and Redding (2013).
Consider how contract imperfections, given by l, aļ¬ect the cutoļ¬
productivities and the productivity distribution.
