Start: policy makers’ views on macro-finance
- 1. Framing: why study financial cycles?
- Financial cycles as part of macro-financial linkages
“Theories” on why and how financial cycles arise
- 2. How to Identify Financial (and Business) Cycles
- Different approaches for measuring
- Level vs. trend cycles: technical and policy differences
- 3. How to increase use of financial cycles in policy
- Link with forecasting and macro-financial linkages
- Financial stability analyses, vulnerabilities, and cycles
Link with policies (macroprudential, e.g., CCyB)
- Macro-financial linkages tools at Federal Reserve Board
“I wasn’t used to thinking of the banking and financial sector as having such a critical role…Floating exchange rates, tightening budgets, liberalizing markets and worrying about wages were all according to the book…Tesobonos were not” Stanley Fischer, First Deputy MD, IMF, Euromoney, September 1997 “In the interest of full disclosure: This is a first pass by an economist who, until recently, thought of financial intermediation as an issue of relatively little importance for economic fluctuations…” Olivier Blanchard, Chief Economist, IMF, WP/09/80, April 2009

Before e the cris isis is
- Long shadow of two separate strands in literature
Efficient financial markets. And RBC, new-Keynesian
- Limited evidence on supply-side channels
“Finance is a veil”
Th The cr cris isis is highlighted many questions-old, new
- Financial markets less than efficient. Finance
matters in originating and propagating shocks
- Importance of macro-financial linkages
After r the cris isis is more evid idenc ence
- Empirical research on macro-financial linkages
Much on demand-side; some on supply-side channels

Part of question: “Why Macro-Financial Linkages”?
- Theories suggest financial cycles can arise, related
to, but also independent of business cycle
- Demand: financial accelerator mechanism
- Supply: also accelerator, and intra-financial system
Mechanisms matter for measurement and policy!!
- Empirical approach for measuring will (thus) vary
- Demand side
Overall/Sectoral, to identify accelerator effects
- Supply side
Study (intra-) financial system, to get miss- pricing/allocation
Endogenous developments in financial markets propagat gate and amplify fy shocks ks in real economy
Corporate finance foundation
- Financial positions of agents (asset prices, debt,
wealth) affect access to finance → real outcomes
Variations built into D(S)GE models
1. External finance premium (Bernanke-Gertler, 1989) 2. Collateral prices (Kiyotaki and Moore, 1997) 3. Debt deflation (Irving Fisher, 1933), more recently 4. Open economy models (Krugman, 1999, etc.)
Various other frictions (cash-flow, working
capital, trade finance, default probabilities, etc.)
Frictions related to heterogeneity, project and
technological choices, productivity, governance
Financial frictions operating via labor markets
- Demand: firms’ financing constraints affect hiring
- Supply: housing/mortgages
Information, uncertainty
- More volatility, less precision in signals/credit standards
ZLB/ELB can aggravate effects/externalities

Net worth, asset prices decl
cline ine and collateral less valuable → final borrowers (corporations, households, sovereigns) have less access to finance, worsens real economy, adverse erse feedba backs cks – “Busts:” Asset prices drops, credit declines, external financing crunches with adverse real consequences
Net worth, asset prices incr
crease ase and collateral more valuable → final borrowers have more access to finance, strengthens real economy, positiv itive e feedbac backs ks
- “Booms:” Asset price booms, credit increases, capital
inflows, lead to amplified positive real consequences
Financial system (supply side) can be a source of shocks,
amplification and propagation. Several channels:
Bank
nk lend endin ing g and d bank nk capital pital chan hannels els
- Some borrowers (households, SMEs) are bank dependent.
Traditional channels of transmission of monetary, regulatory
- policies. New work on unconventional policies, QE, etc.
Leverage
erage and d liquidi quidity ty chan annels ls
- Like capital channel, but not just for banks. Plus indirect, asset
price effects through (common) exposures. And (complex) interactions among financial intermediaries and markets, through traded securities, etc. Newer area of research.
All show how financial sector create, amplify shocks Cros

- Many externalities, market failures within financial system
leading to system risk. Interacts with time-series dimension

Financial Accelerator again: shocks to assets or equity affect bank → amplify, propagate shocks
- 1. Capital shocks
- 2. Asset price shocks
- 3. Liquidity shocks, fire sales
- 4. Leverage cycles
Interact with “standard” FA → double whammy → General equilibrium → virtuous+vicious cycles
- Intra-system dynamics: not (ye
yet) well understood erstood

HH ROW OFI NFC MFI GOVT INS Two main (complementary) approaches in the
business and financial cycle literatures
- 1. “Classic cycle” approach (turning-point analysis)
Identify significant turning points (peaks and troughs)
- 2. “Growth cycle” approach
Detrend: define cycle relative to a trend
⇒ Business Cycles (BC) and Financial Cycles (FC)
13
NBER-based algorithm to determine peaks, troughs Based
- n Burns, Mitchell (1946) and Bry, Boschan (1971) for GDP,
typically Quarterly frequency (BBQ)
- Popularized for business cycles by Harding and Pagan
- Can include Markov Switching (MS) models here (Hamilton, 89)
Simple measures, as input for further analyses:
- Average duration/typical pattern of cycle: relevant for policy
- Explain duration/amplitude/slope by various macro-financial variables
and (monetary and fiscal) policy
- Analyze boosts and busts (“financial crisis”) as extremes FCs
- Analyze degree of BC/FC synchronization within, across countries
Concordance index (Harding, Pagan 2002b): fraction of time any two series are in the same phase in their respective cycles Amplification across FCs and across countries
14
Hodrick-Prescott (HP) filter, with frequency range
- Idea: measure “excessive credit” (new debt contributing less
to growth (lower productivity, for assets, e.g., housing)
- Typical: one-sided HP filter with λ=400,000) for long FC
E.g., Basel committee For credit-to-GDP:, as in CCyB Can augment end points w. forecasts before de-trending
- Performs well as early warning indicator of future crises
Latent Dynamic Factor, Frequency Domain
Analysis, Spectrum, Multivariate (MVF), etc.
- Latent factors, relate to many variables, including financial
Use state-space, spectrum representation, Kalman filters, etc. Detect commonalities, obtain unique cycle, w/o assumptions
- MVF variations much used (IMF, BIS, Norges bank, etc.)
Can robustly add variables (i.e., output gap est. Borio et al (2013)), improve forecasting (Liu, Matheson, Romeu, 1998)
- Frequency Domain Analysis, Spectrum: more recent
15
Claessens et al. (2011, 2012): analyze FC and BC
in 21 (+23) AM (+EM) countries; 1960-2007. Use turning point analysis
- FC (credit, house, equity prices): long, severe, highly
synchronized within countries
- Strong linkages between BC and FC, accentuate each other.
Recessions with financial disruptions longer and deeper
- Now in Claessens et al. 2016 for 75 countries 1960-2015
Drehmann et al. (2012), Borio (2012): for 7 AMs.
Use pre-specified frequency-based filter method at which FC is assumed to operate
- FC best captured by house prices and credit, not by equity
- Peaks strongly associated with systemic financial crises
- Duration and amplitude of FC increased since 1985 (from 11
to 20 years)
16
“Fundamentals-based” models
- Dynamic-panel estimates with country-specific intercepts.
e.g., Debt=f(GDP, real rate, country-specifics, lagged debt)
- “Long-run equilibrium” models. e.g., house price =
f(income, interest rates, credit, equity prices, demographics), + affordability, risk-taking, standards
Intra-financial sector models with time/cycle
- Regime-shifting models; Joint Probability of Default (JPoD);
Systemic contingent claims analysis (SCCA); Distance-to- Default; Expected Default Probabilities (EDF); SRISK; DIP; CoVaR: Diebold-Yilmaz, etc. etc. Some market price, some accounting-based. Most use interdependency, “jointness” of distress probability
17
Is it the level or growth that worries? Both matter Level-based
Simple, but not country-specific, pros and cons Still: Parametric or Non-Parametric? What selection criteria?
Trend-based
HP, other uni- or multivariate frequency filters? Multivariate approaches: what to include? How to deal with end-of-period, new data? Short- vs. long- term trend?
Frequency of updating, use market prices yes/no? All use (some) real quantities, so what price?
⇒ FC (and BC) thus vary!!

Countries facing possible trade-off between economic stimulus and financial stability
Risky to rely on pure data (-mining
Correlations can be positive due to other factors
- Fundamentals (shocks) and Policy actions (fiscal, monetary)
- International, via risk-sharing and otherwise
Without real connection between two economies
- Second best: e.g., more markets does not mean necessarily
higher welfare
Heterogeneity: cyclical positions, structural
features, variations in financial systems
No formal benchmark—how to define excess? Financial cycles are very low-frequency: what about
short-term movements? Ignore? ⇒Need to be able to tell story of the “why and what”

Stock and Watson type GDP “predictions”
- Include financial variables: stock returns, capital
flows, interest rates, valuation measures, commodity prices, risk factors, others
Gilchrist, Yankov, and Zakrajsek (2009), etc.
But allow for heterogeneity across countries
- EMs: Stock returns, term spread, default spreads,
portfolio flows help predict output growth. Global factors (corporate spreads, commodity prices) also
- US: Term spread, stock returns, commodity prices
lack any predictive power; increase in portfolio flows indicate future declines (Banegas, 2016)

and/or and
And not much new or exotic either in recent credit/property booms and busts
- Confidence underpinned by new growth and financing paradigm (US,
Eastern Europe, Ireland, Spain. Earlier: Japan, East Asia)
– Rising debt and leverage across sectors
- Lax bank supervision (Ireland, Iceland, US. Earlier: Chile, Scandinavia)
– High exposures to real estate, high leverage – Declining lending standards, focus on collateral not risk, predatory lending
+ Increased competition in banking (Ireland, Iceland, euro area. Earlier: Chile, Mexico 1990s, Russia)
- Funding availability & low cost
– Wholesale (Ireland, Iceland, Northern Rock), cheap HQ funding (EE) – Mismatches: FX (Eastern Europe. Earlier: Asia), indexing (Iceland), duration (EE) – Inflated credit ratings (strong fiscal Ireland and Iceland, growth in most EE). Earlier: many emerging markets
→ New trigger/twist: money market runs, shadow banking, run on repos, spill-over of subprime/structured finance shock to non-US banks
1.
Historical: flow of fund cross-check
- Check that the real, overall forecast is consistent with the financial flows of
funds patterns (e.g., bank capitalization and credit growth). Less today
2.
Sub-sector, granular forecasts
- Make forecasts consistent with relevant financial sector developments. E.g.,
housing starts to be consistent with patterns in supply of housing finance, house prices,... Corporate sector investment to be consistent with overall external financing conditions…. Etc.
3.
Model-based forecasts
- Various DSGE-type + other models to assess overall impact of financial
conditions on real and other forecasts. And do up/down scenarios (“alt sim”)
- Examples: FRBNY DSGE and FRB models. Tend to be similar, but financial
intermediation is still hard to model, often have to resort to spreads
4.
Financial stability analyses
- Quarterly internal financial stability reports: assesses vulnerabilities,
spillovers to the real economy, domestic, international. Various tools
- Ad-hoc analyses, as risks/vulnerabilities appear
