Introduction

2

Two narratives
The St. Louis Fed recently changed its approach to near-term
U.S. macroeconomic and monetary policy projections.

remarks delivered at the Society of Business Economists Annual Dinner, London, U.K. June 30,
2016.

Louis Fed commentary. June 17, 2016.

An older narrative has likely outlived its usefulness.
A new narrative is replacing the old narrative.
In this talk, I will describe in more detail the differences
between the two narratives.

3

Nature of the old narrative
In the old narrative, there is, axiomatically, a unique long-run
steady state which is essentially an average of the past.
The economy is converging—all values for key
macroeconomic variables are tending toward steady state
values.
Inflation and unemployment gaps are near zero—business
cycle dynamics have played out seven years after the end of
the recession.*
Implication: The policy rate would likely rise over the
forecast horizon to be consistent with its steady state value.
* For example, see J. Bullard, “Fed Goals and the Policy Stance,” remarks delivered at the
Owensboro in 2065 Summit, Owensboro, Ky. July 17, 2014.

4

Nature of the new narrative
In the new narrative, the concept of a single, long-run steady
state is abandoned.
Instead, there is a set of possible regimes that the economy may
visit.

Nonstationary Time Series and the Business Cycle,”
Econometrica, March 1989, 57(2), 357-384.

Switching, MIT Press, 1999.

5

More on the nature of the new narrative
Regimes are viewed as persistent, and switches between
regimes are viewed as not forecastable.
Optimal monetary policy is regime dependent.
Implication: The policy rate would likely remain essentially
flat over the forecast horizon to remain consistent with the
current regime.

6

The forecast based on the new narrative
A simple forecast over the next two and a half years:*





Real GDP growth
Unemployment
Trimmed-mean PCE inflation
Policy rate

2 percent
4.7 percent
2 percent
63 basis points

Risks associated with this projected policy rate are likely to
the upside.

Previous Narrative and
the End of Its Usefulness

8

St. Louis Fed’s previous narrative
Typical medium-term forecast during the past several years:





Output growth above trend.
Unemployment declining.
Inflation (net of commodity-price effects) overshoots 2 percent.
Policy rate increases to be consistent with the unique steady
state.

Some aspects worked well from the second half of 2013 to
the first half of 2015:
 Average quarterly growth: 2.7% > 2% (trend).
 Unemployment declined by 2 percentage points.

However, inflation barely moved.

9

The end of the usefulness of the old narrative
The usefulness of our previous narrative may have come to
an end:
 Output growth has arguably slowed and is currently not far
from a 2 percent trend.
 Unemployment may not fall much below current values.
 Trimmed-mean inflation is close to target but not rising rapidly.

If there are no major shocks to the economy, this situation
could be sustained over a forecasting horizon of two and a
half years.

A New Narrative

14

A new narrative based on regime switching
New narrative: We want a manageable expression of the
uncertainty surrounding medium- and longer-term outcomes.
Fundamental factors determine the nature of the regimes:
1. Productivity growth.
2. Real interest rate on short-term government debt.
3. State of the business cycle.

Optimal monetary policy is regime dependent.
Regime switches are not forecastable—viewed as “risks.”
Forecast limited to a horizon of two and a half years—no longrun projections.

15

Productivity regimes
One important fundamental is productivity growth.
Average labor productivity growth has been low since at least
2011, which we view as a “low-productivity-growth regime.”
We assume that we will remain in the low-productivity (and
hence low-real-GDP-growth) regime through the forecasting
horizon because regimes are persistent.
Higher productivity growth was observed in the recent past.
A switch back to a high-productivity-growth regime is an
upside risk.

The low-productivity-growth regime

17

Real-interest-rate regimes
The real rate of return on short-term government debt, r†, has
been exceptionally low, which we view as a “low-real-rate
regime.”
 Appears to be highly persistent.
 For forecasting purposes, we assume that we will remain in the
low-real-rate regime through the forecasting horizon.

The alternative regime has a relatively high real rate.
 A switch to a high-real-rate regime is viewed as a risk.

Interpretation:
 Abnormally high liquidity premium on government debt.
 Real returns on capital are not low.*

19

State of the business cycle
Another important fundamental is the possibility of recession.
Currently we are in a “no-recession” regime, but it is possible
that we could switch to a recession state.
All variables would be affected, but most notably, the
unemployment rate would rise significantly.
We have no reason to forecast a recession given the current
state of the U.S. economy.
The possibility of a recession is a risk to the forecast.

Recession probability is low

Methods,” Journal of Business and Economic Statistics, January 2008, 26(1), 42-49. Last observation: April 2016.

21

The Policy Rate Path

22

Policy rate path
The policy rate path (63 basis points) supporting our output,
unemployment and inflation forecasts is regime dependent.
Unemployment and inflation gaps ≈ 0.
A Taylor-type rule collapses to a Fisher equation
i = r† + π e + ϕπ π GAP + ϕu u GAP = r† + π e
i = 0.63% and π e = 2% imply (i – π e) = –1.37%
Very close to r† = –1.41%, the one-year ex-post real interest
rate on government debt.

Policy rate path

24

Risks to the forecast
Fundamental factors could switch into new regimes, in which
case monetary policy would have to react.
Phillips-curve effects:
 In our narrative, a strong labor market (low unemployment)
does not put significant upward pressure on inflation.
 A risk is that Phillips-curve effects could reassert themselves
and drive inflation higher.

Inflation expectations:
 Low market-based measures are at odds with our forecast.

Asset price bubbles.

Conclusion

St. Louis Fed’s characterization of the macro outlook
r† = real rate of return on short-term government debt
λ = productivity growth

High r †

Low λ

policy rate path

High λ

No recession

Low r †

Low λ

Baseline forecast

27

Conclusion
The projected policy rate path is the main difference in the
new approach.
Old narrative:
 Steep policy rate path, dictated by convergence to the single,
long-run steady state.

New narrative:
 Flat policy rate path, conditional on the current regime.
 If a regime switch does occur, the policy rate path would have
to change appropriately—it is still data dependent.
