Liquidity Coinsurance in Syndicated Loan Markets
(joint with Filip Zikes and Kevin Kiernan), under revision for the Journal of Finance |
[ Slides ] [ Replication code ] [ Appendix ] |
Abstract:
We develop a simple model of the liquidity and insurance capacity of the interbank network arising from loan syndication.
We find that the liquidity capacity has increased significantly following the introduction of liquidity regulation, and that
the liquidity co-insurance is economically important for the corporate sector. We also find that borrowers with higher reliance on
credit lines have become more likely to obtain credit lines from syndicates with higher liquidity capacities.
The increase in liquidity capacities and the assortative matching on liquidity characteristics has strengthened the importance of
large banks as liquidity providers to the corporate sector.

The Collateral Channel and Bank Credit
(joint with Arun Gupta and Horacio Sapriza),under revision for the Journal of Financial Economics |
[ Slides ] [ Replication code ] [ Appendix ] |
Abstract:
We identify the firm-level and aggregate effects of the collateral channel using detailed bank-firm-loan level data that allow us
to observe the pledging of real estate collateral and to control for credit demand and supply conditions. At the firm level,
a 1 percent increase in collateral values leads to a 12 bps higher credit growth, whereas, in the cross-section of MSAs, the average
elasticity of credit to collateral values is 7 times larger. Our estimates imply that as much as 37 percent of employment growth over
the period from 2013 to 2019 can be attributed to the relaxation of borrowing constraints at bank-dependent borrowers.

The Secondary Market for Syndicated Loans
(joint with Jan-Peter Siedlarek), in preparation |
[ Slides ] [ Replication code ] [ Appendix ] |
Abstract:
We document an active secondary market for shares in syndicated term loans using confidential supervisory data.
While most of the existing literature examines trades close to origination, this paper is the first to study the secondary market
spanning the lifecycle of a syndicated term loan. We establish a set of novel empirical facts concerning the trading of loan shares
after origination and identify the key participants and their trading patterns. We characterize the determinants of existence of
an active secondary market, the size of turn-over of lender shares, and the resulting allocations of credit exposures.
Higher nonbank participation is associated with greater trading activity over the lifecycle of a syndicated loan.

Collateral Heterogeneity and Credit Market Frictions
(joint with Marios Karabarbounis, Patrick Macnamara, and Horacio Sapriza), in preparation |
[ Slides ] [ Replication code ] [ Appendix ] |
Abstract:
While the distinction between firm borrowing by pledging physical assets and firm borrowing by
pledging future cash flows is becoming central in recent macro-finance studies, there is little work making this distinction
within quantitative models of firm financing. We build a structural model with heterogeneous firms that optimally choose between
asset-based or cash-flow-based debt. We show that the choice of collateral type is important to evaluate the overall impact of
credit market frictions. We discipline the model with U.S. bank-firm-loan level administrative data, which provide detailed
information on the type of collateral pledged across the firm size distribution including both public and private firms.
We find that low-productivity firms prefer to pledge their assets, because the ongoing value of the firm is small,
while more productive firms with expected large future cash flows are better off pledging their future cash-flow as collateral.
This result has sharp implications for the effect of financial frictions on real outcomes: standard financial shocks such as
credit tightening from declines in asset prices have smaller effects in our framework, because they affect smaller and
mainly unproductive firms.

Rewiring repo
(joint with Jin-Wook Chang,
and Elizabeth Klee) , in preparation |
[ Slides ] [ Replication code ] [ Appendix ] |
Abstract:
We study the structure and efficiency of the repurchase agreement (repo) market in allocating cash and collateral across two segments.
The first segment is a decentralized tri-party repo market characterized by established and persistent long-term relationships between
dealers (borrowers) and cash lenders. The second segment is a centrally-cleared interdealer market that reallocates excess cash borrowed
in the decentralized market to dealers with cash deficits. We develop a model of a networked repo market with strategic interactions among
dealers who compete for funding from a limited pool of cash allocated across different lenders. The model allows us to disentangle supply
and demand factors that determine the clearing of excess demand for cash in the centralized market. We estimate the supply and demand factors
along with the supply and demand elasticities for cash and collateral. We determine conditions under which the market could become unstable as
a result of competition among dealers and capacity constraints of lenders. Our results are important in designing efficient market interventions
to stabilize the market as well as in understanding how monetary policy tools such as the ON RRP facility affect the market.

In Search of a Risk-Free Asset

Abstract:
I examine the role of costly consumer search for the pricing of deposits. Estimates of a model of heterogeneous search cost households reveal a large
fraction of high-search-cost depositors composed of elderly and less financially sophisticated households. Those households grant banks
significant monopoly power that results in low and asymmetric interest rate pass-through. The predictions of the estimated model are consistent with
responses in the Survey of Consumer Finances to questions related to financial sophistication, search for investment return, and deposit allocations
across multiple bank accounts. The estimated model also reveals a non-monotone relationship between bank entry, deposit rates, and consumer surplus.

Limited Deposit Insurance Coverage and Bank Competition
(first draft 2014)
[ Slides ]
[Replication code ]
(joint with Oz Shy and Rune Stenbacka ),
Journal of Banking and Finance,
Volume 71, October 2016, Pages 95-108

Abstract:
Deposit insurance schemes in many countries place a limit on the coverage of deposits in each bank.
However, no limits are placed on the number of accounts held with different banks. Therefore, under
limited deposit insurance, some consumers open accounts with different banks. We compare three regimes
of deposit insurance: No deposit insurance, unlimited deposit insurance, and limited deposit insurance.
We show that limited deposit insurance weakens competition among banks and reduces consumer welfare as
well as total welfare relative to no or unlimited deposit insurance.

Credit Market Shocks and Economic Fluctuations: Evidence from Corporate Bond and Stock Markets

Egon Zakrajsek ),
Journal of Monetary Economics,
Elsevier, vol. 56(4), pages 471-493, May 2009.

Abstract:
To identify disruptions in credit markets, research on the role of
asset prices in economic fluctuations has focused on the information
content of various corporate credit spreads. We re-examine this
evidence using a broad array of credit spreads constructed directly
from the secondary bond prices on outstanding senior unsecured debt
issued by a large panel of nonfinancial firms. An advantage of our
``ground-up'' approach is that we are able to construct matched
portfolios of equity returns, which allows us to examine the
information content of bond spreads that is orthogonal to the
information contained in stock prices of the same set of firms, as
well as in macroeconomic variables measuring economic activity,
inflation, interest rates, and other financial indicators. Our
portfolio-based bond spreads contain substantial predictive power
for economic activity and outperform - especially at longer
horizons - standard default-risk indicators. Much of the predictive
power of bond spreads for economic activity is embedded in
securities issued by intermediate-risk rather than high-risk
firms. According to impulse responses from a structural
factor-augmented vector autoregression, unexpected increases in bond
spreads cause large and persistent contractions in economic
activity. Indeed, shocks emanating from the corporate bond market
account for more than 30 percent of the forecast error variance in
economic activity at the two-to four-year horizon. Overall, our
results imply that credit market shocks have contributed
significantly to U.S. economic fluctuations during the 1990--2008
period.

Endogenous Organizational Structure and Internal Allocation of Capital in Banking
(joint with Tszkin Julian Chan
and Ben Craig ), under major revision
|
[ Slides ] [ Replication code ] |
Abstract:
We document that large US bank holding companies have organizational
structures composed of a large number of individual subsidiaries with
different geographic or functional specialization. Moreover, and much
less known, the organizational structures across different holding companies
vary in their network characteristics. We combine information from
the organizational structure of bank holding companies with data
from the balance sheets and income statements of the holding company bank
and non-bank subsidiaries to construct a unique dataset of the internal
allocation of funds within a conglomerate. We document that these internal
capital flows are sizeable and increase with the cost of external funding.
Furthermore, banks within a conglomerate with higher centrality in the organizational
network receive disproportionally higher funding controlling for profitability
and investment opportunities. We also show that previous research on the internal
allocation of capital in banking, which did not control for the network structure
and the endogeneity of organizational structure of bank holding companies,
significantly underestimates the role of the internal capital markets.
