FOMC SEP Target Rate Projections How are they determined and what do they tell us about the Fed's policy
decisions?
I. ABSTRACT Previous work has focused on understanding the extent to which the latest information
available, including other forecasts, is being used for revising the set of FOMC’s projections and
assessing their overall predictability. In this paper, I present an extension of this work by studying
the target rate lift-off projections. I evaluate how the public can quantify the extent to which
changes to expectations of future unemployment, headline inflation, and stability in both the
energy prices and financial markets will influence future monetary policy decisions. Can these
projections help us understand the timing and pace of the recent target rate lift-off? What about
the policy decision to keep near zero Fed Funds Rate Target for 7 years?
This is an important study because it evaluates the overall role of the Summary of Economic
Projections (SEP) in reassuring the credibility of monetary policy in the US. In particular, it has
been well documented that a deterioration in the credibility of a central bank has irreversible
implications for the functioning of the domestic economy and, in the case of the US, it also plays
a key role internationally by influencing exchange rates with the world’s largest reserve currency
and the direction of global capital flows. To this end, I find that the FED’s SEP projections are
consistent with standard macroeconomic relationships and, in particular, the extent to which the
rate lift-off was postponed can be attributed to the large influence of an unexpected decline in the
world price of crude oil in 2014-15. Regression estimates show that every 10% decrease in the
price of WTI led to a 0.10ppts downward revision of the SEP forecasts across all horizons.
Moreover, current SEP lift-off projections continue to suggest an annual 1 percentage point
increase in Fed Funds Rate until 3 percent is reached provided the price and unemployment levels
oscillate around current values.

II. BODY
1. Overview of FOMC projections
Given the extent to which monetary policy depends on credibility and the degree to which the
public is able to anticipate policies, there is no doubt that both the communication strategy and the
signaling channel of a central bank play an essential role in today’s macroeconomic set of policy tools.
As a result, it is no surprise that over the years the FED has been increasingly inclined towards
transparency as a way for policies to be adequately internalized by the public. Arguably, a key
component of this communication strategy can be found explicitly in the shape of official forecasts.
This was stressed in 2007 when the FED began releasing its Summary of Economic Projections in
order to complement the FOMC post-meeting minutes.
" The Federal Open Market Committee (FOMC) announced on Wednesday that, as part of its ongoing commitment to improve the accountability and public understanding of monetary policy making, it will increase the frequency and expand the content of the economic projections that are made by Federal Reserve Board members and Reserve Bank presidents and released to the public. "1
Since then, the FOMC began making quarterly releases of forecasts with the projected level of
GDP growth, inflation and unemployment expected for the end of every year. Although multiple
forecasting horizons are presented –including one for the current year, the two following years, and,
sometimes, a fourth year–, these summaries are limited because the whole distribution of participants’
projections is not released. Only the range and central tendency (which excludes top and bottom 3
projections) of the projections are made available to the public. Appendix 1 and 2 show examples of
the SEP releases found after each FOMC meeting.
While an anonymized list of the entire distribution of the individual votes can be found for some
years, this is only made available to the public after a 5 year lag making it very difficult to conduct
robust statistical analyses of variables in question. As a result, these restrictions have made it
substantially cumbersome to use econometric methods to examine the extent to which such
projections can help map the trajectory of policy decisions. Nevertheless, starting in 2012 the set of
1 Press Release Nov. 14, 2007

variables in the SEP was expanded so as to also incorporate forecasts for the target interest rates. Not
only do these projections complete the basic set of variables that represent the core of monetary policy
but they also come with more information themselves since the whole distribution (as opposed to
only the range and the central tendency) of individual projections is released.
While one would think that the release of such projections would immediately bring about a big
breakthrough in the study of monetary policy, research in this field remains limited and only a few
economists have assessed the extent to which the consistency and timing of monetary policy can be
understood using the information provided by these forecasts. However, predicting the timing of
monetary policy decisions continues to be very relevant today given that the Fed has proven to be
ready to increase interest rates by announcing its first rate hike decision at the end of 2015.
Since then, however, monetary policy has remained unchanged despite the great expectations that
the Federal Reserve would continue to tighten monetary policy lifting the federal funds target at least
two more times in 2016. While many have expressed their belief that FOMC projections have not
improved the public’s understanding of monetary policy, in this paper I will argue that the SEP may
actually provide a good roadmap for the future of monetary policy as it provides a neat illustration of
the Fed’s policy reaction function provided stability in the price and unemployment levels and specially
now that we are moving away from the Zero Lower Bound (ZLB).

2. Target rate projections ~ in and out of the ZLB
Figure1(Rangeofprojectionsforeachyeargoinglefttorightfromoldesttonewest)
Given that monetary policy must remain credible for it to work, one would expect that on
average policy makers follow a policy path that is substantially similar to their projected path.
However, if we were to take the FOMC’s target rate projections made from 2012 through 2015
at face value, the recent rate hike seems to be long overdue. The mean of the SEP target rate
projections was mostly over 0.5 since 2013 for all forecasts made more than 2 quarters before
the end of the year being forecasted. (see Figure 1) Marquez and Herrador in 2016 note that since
2008 FOMC’s projections show errors that are large, one-sided, and persistent. They ask how
can decisions be understood if the FOMC doesn’t provide a mapping from projections to
decisions?
With regards to this question they highlight two points that need to be taken into
consideration. First, forecasts from alternative sources over this period of time were not any
better than those of the FOMC. Second and more importantly, the fact that FOMC participants
are not impartial observers of their own forecasts but rather must influence the economy so as
5
to meet their dual mandate. However, unemployment and inflation projections were also
characterized by long periods of over-optimism followed by equally long periods of over-
pessimism. To the extent that the variables being forecasted are endogenous, a failure to correctly
assess future conditions of the labor market as well as the price level will influence the predictions
of the projected policy response. While some may consider this a weakness, this is why it remains
important to study the SEP because, in spite of these projections being systematically wrong,
consistency in their over persistence may actually offer important information about the FOMC’s
implicit reaction function.
This particular case is well illustrated by the recent work of Kahn and Palmer in 2016, who
used the SEP to estimate an approximation of the FOMC’s response function. They estimated
the relationship between the target rate forecast and the rest of the forecasts by regressing the
projected Federal Funds Rate on its fourth lag, a constant, the deviation of headline inflation
from 2 percent and the deviation of the unemployment rate from dynamic estimates of the natural
rate, they constructed coefficients that were then used to historically show the path of a counter
factual implied Fed Funds Rate. Surprisingly these fitted values resemble the actual policy
responses to inflation and unemployment from 2001 to December 2008, before policy became
constrained by the Zero Lower Bound (ZLB) (see Figure 2).
Figure 2: Fed Funds Rate Target –Actual vs Projections from the SEP- (Source: Kahn and Palmer)

Two things are appreciated in Figure 2, which shows the counter-factual scenario that uses
the predicted values for pre-2008 using the regression results from the whole sample. First, there
seems to be evidence for a shadow target rate implicit function that doesn’t materialize because
policy makers are constrained by the ZLB. However, to the extent that SEP relationships are an
accurate measure of the non-ZLB reaction function, understanding the SEP forecast may actually
give the public a good mapping of policy going forward. This is important as we move closer to
the highly anticipated 1% level of the target rate by the end of the year.
The second and subtler point is that these projections tend to systematically under-predict
the actual target rate by on average 2 percentage points. This may be attributed to two things.
First of all, there was no quarterly SEP available prior to 2007 so it is difficult to estimate shifts
in the FED’s policy preferences in particular as the Board has changed its composition of central
bankers. One example of intra-mandate variations in preferences, is the difference in policy
between the Bernanke and Yellen mandate, which was estimated to be as large as 0.6 percentage
points by Marquez and Herrador in 2016.
Moreover, the second point worth noting is the presence of a large degree of endogeneity
and the small sample of SEP projections. Not surprisingly the point estimates are very sensitive
to different regression specifications, the inclusion of control variables, and using other
estimation methods other than OLS. The fitted values in Figure 2 come from a regression where
the coefficient on the inflation gap in the historical policy reaction function is 1.3, the coefficient
on inflation in the SEP reaction function is 1.7, and the constant term is roughly 4 percent.
Nevertheless, one needs to take caution when reviewing these results. In particular, when using
a FIML specification Marquez and Herrador find that there is upward bias of at least half a
percentage point in the OLS estimates of the implied reaction function to unemployment and
inflation. Figure 2.1 shows an alternative specification that excludes the fourth lag. Notice that
the variation in Fed Fund’s Rate target is much later in this case. Figure 2.2 shows the fitted values
of a different specification that assesses the levels as opposed to the gap between the independent
variables and their natural levels. In both cases, the predicted values make the case for a two to
three years earlier lift-off. This suggests that the Fed’s predictability may involve a further
understanding of its level of persistence and their views in the perceived natural rates of
unemployment.

3. Other SEP projections In general, what remains true about the SEP is that there is a period of over-optimism
followed by a period of mixed expectations. Figure 3 shows the set of projections made for each of the 7 years after the crisis for the rate of unemployment and GDP growth. It depicts how the ranges of the SEP projections (left to right from the earliest to the latest set of forecasts made) converged to their actual value. These figures clearly illustrate the large extent to which every participant in the FOMC persistently failed to recognize the magnitude of the 2008 crisis but was
8
overoptimistic about the extent to which monetary policy was going to boost growth and bring unemployment down. Forecasts improve starting by the set of projections made for 2013. However, while the unemployment forecasts were for the most part over-pessimistic, the GDP growth projections continued to be over optimistic. Altogether, as the economy moved out of the crisis, the sets of projections at every FOMC for these two indicators were less disperse suggesting an increase in the level of consensus about the direction of the economy.

Things are much grimmer for inflation. Figure 3 shows the set of projections made for each
of the 7 years after the crisis for PCE headline inflation.
Although the extent to which there is persistence in the over-projecting of inflation is much
lower than for unemployment and GDP growth, the FOMC was not been able to provide either
accurate nor precise forecasts for such an indicator. Most of the discussion about this is centered
around the unexpected fluctuations in energy prices and the sudden changes in the valuation of
financial assets. In particular, during this period we saw two sharp declines in the price of a barrel
of oil from mid $90s down to mid $40s in 2008 and from $110 early in 2014 down to mid $40 in
2015 and further down to mid $20s at the start of in 2016.
Kahn and Palmer provide an interesting claim about the impact of missed inflation projection
on the FOMC’s ability to accurately forecast their target rate. They claim that “the FOMC’s
anticipated response to projected increases in inflation was the primary factor responsible for the

missed [target fed funds rate] projections.” Although fluctuations in the price of financial assets,
as illustrated in Figure 4 by the S&P500 index, do have statistical influence on the interest rate
forecasts (to be elaborated over the following sections) there is no immediate trend that would
at first sight suggest it had an influence on the delay of the recent rate hike decision.
4. Projecting a Lift-Off
The sample of FOMC target interest rate projections is much more reduced than the
projections for the other macroeconomic indicators since they began being released on 2012.
They are consistently off from the actual effective funds rate because they mistakenly anticipated
an earlier realization of a projected rate hike, which was not experienced until the end of 2015.
Instead of being taken at face value the information provided by these projections could be read
as a roadmap or plan for the pace at which policy makers expect rates to return to their long run
equilibrium.
Figure 6 illustrates a number of curves that portray the schedule of interest rate projections
released for each meeting since June 2012. Notice that, while the projection schedule keeps being
pushed to the right, the slope of the schedule remains pretty much constant overtime. In other
words, although the FOMC’s projections are being revised to convey their decision to keep
postponing rate hike, their intention to increase interest rates anywhere between 100 to 75 basis
points per year remains constant. Perhaps the most interesting feature of Figure 6, which shows
the average of the rate hike schedule presented at every SEP since June 2012, is the considerable
rescheduling of the interest rate hike plans that occurred from 2014 throughout 2015 as
appreciated by the dotted lines to the right.

Figure6:SEPtargetrateforecasts
This highlights the point made earlier about the drop in energy prices allowing the Fed to
stretch its expansionary policy for about another year without having to worry too much about
inflation. Although another consideration, which is to a great extent related to the fall of energy
prices, is the strengthening of the dollar in particular relative to emerging market currencies, I will
not examine this issue in this study. If at all it would amplify the anticipated effect of a decline in
inflation due to a lowering in the cost of importing to the US. Figure 7, groups the average FOMC
projections made in any given year. We observe considerable overlap between the rate hike
projections in 2013 and 2014 but a clear difference between these and 2015.

Figure7
The consistency in the pace (illustrated by the slope of the previous two charts) at which the
FOMC has conveyed its expectations to increase the target interest rate reflects important
considerations with regards to whether monetary policy decisions are being informed by standard
macroeconomic models. Is the FED’s decision to raise rates considering both objectives of its dual
mandate to attain full employment and price stability? The answer to this question will be at the core
of the econometric work presented in the following sections.
The road maps in Figures 6 and 7 should be seen as a base for future policy decisions, but may
change as new data comes in. What remains true for the years to come is that unexpected shocks to
inflation may be either temporary or permanent. The nature of these shocks will influence expectations
about future inflation and will hence determine whether the FOMC chooses to adjust by shifting the
policy schedule rather than changing the pace of the rate hike. On the other hand, it is remains difficult
to say anything about how the Fed’s reaction function will change to unexpected changes to
unemployment because since 2008 we have not experience any other substantial shocks to the labor
market.
However, we can already see from Figures 8 that the ranges of FOMC forecasts for headline
inflation, GDP growth, and unemployment are flat and tight around 2, 2.5, and 5 percent respectively,
which does suggest that the Fed may have an agenda to pursue macroeconomic stability around those

values. While this could be problematic because ideally we would want to have large enough variation
in our explanatory variables to explain changes in our dependent variables, there seems to be enough
variation in our sample to provide a robust statistical relationship across variables even when different
measures of the FOMC are chosen.

The rest of this paper goes into detail as it aims to understand the dynamics behind the patterns
that we have been discussing so far. It provides a statistical examination of the extent to which
macroeconomic indicators are exposed to exogenous shocks to energy prices and financial assets. In
particular, it examines the influence that these shocks have the on distribution and realizations of the
FOMC SEP interest rate projections. The regressions ahead study the consistency of interest rate
forecast to changes in expected inflation and unemployment when looking at a variety of
specifications, time periods and estimation methods. Section 5 examines the existing literature on the
SEP’s. Section 6 goes into detail about how the data was assembled for this study. Section 7 highlights
the different econometric specifications considered in this study. Section 8 shows the most important
results and compares them against different robustness checks. Section 9 through 12 look at the
conclusions that can draw from this analysis, the existing limitations and scope for future work.
5. Understanding the SEP in the literature
Previous evidence has mostly focused on the examination of the set of SEP projections as a good
forecasting tool. Romer (2010) documents that the SEP forecasts of concepts that are closely related
are strongly correlated in the expected directions, but that there is nonetheless substantial independent
variation. He finds that a higher 1 percentage point CPI inflation forecast is associated with the GDP
forecast also being higher by 0.75 percentage points and that a forecast of GDP growth being higher
by 1 percentage point is associated with a forecast of the unemployment rate being lower by 0.18
percentage points. Kahn and Palmer (2016) also highlight that one key feature of the FOMC’s protocol
is that participants release projections for several years ahead in each forecast meeting suggesting the
possibility of an intertemporal correlations of forecasts from each meeting. When evaluating the
strength of this correlation they find that for unemployment, the correlation of forecasts one year
ahead is important but it varies from meeting to meeting. However, for inflation, the calculations
reveal that the correlations vary in magnitude and sign.
Further work conducted by Rülke and Tillman (2011) and Nakazono (2013) show substantial
evidence for herd behavior in the forecasts. This is an important consideration given that most
econometric work requires the errors of each individual observation to be independently distributed.
Furthermore, they found instances where non-voting participants submitted “extreme” forecasts to
15
register their disagreements and have some sort of influence over policy decisions by skewing the
perceived mean of the forecasts.
There has also been work by Tillman (2011) that differentiated the statistical properties and the
predictive power of shorter horizon forecasts relative to those with longer horizons depending. In
particular, it is documented that at long horizons the variation of members’ projections contains
information which is more relevant for explaining future inflation than information embodied in the
midpoint. On a more technical note about forecasting efficiency and the study of forecast revisions,
Arai (2014) tests whether the revisions to these projections are unpredictable and finds that FOMC’s
efficiency is generally accepted for inflation, but often rejected for real economic variables, notably
for the unemployment rate. He claims that the rejection is due to the relatively stronger autocorrelation
of unemployment revisions, which may reflect information rigidity of FOMC’s views about
unemployment. Nevertheless, it is found that the joint efficiency of the entire projection is accepted
in most cases.
Marquez and Herrador (2016) document that the FOMC forecast provides little additional
information than the Survey of Professional Forecasters (SPF) released a month before by the
Philadelphia FED. In particular, they find that the FOMC projections are much more influenced by
judgments from the values of the SPF for inflation (𝜋"#$) and unemployment (𝑢"#$) than the actual
present levels of inflation and unemployment. More importantly they note that given the interest-rate
forecast, the upward pressure on the forecast of the federal funds rate from a one percent increase in
the SPF headline inflation forecast needs to be offset by an increase in the SPF unemployment
forecast. They quantify this tradeoff to be 0.43 meaning that an interest-rate forecast remains
unchanged if an increase in πspf is accompanied by an increase in 𝑢spf of 0.43 percentage points. The
implied interest-rate forecast is about 2 percent; if one allows for uncertainty in the intercept of the
mapping equation, then the 66% confidence interval for the interest-rate forecast ranges from 1.4
percent to 2.6 percent. Kahn and Palmer (2016) also conclude that the Summary of Economic
Projections provides insights into FOMC participants’ views on how the federal funds rate target
should respond to inflation and unemployment. Although the projections in the SEP have proved to
be consistently wrong—as have most projections of the future—they do provide information about
the FOMC’s implicit reaction function.

6. Statistical analysis: Data and key variables
As reviewed earlier, since October 2007, FOMC participants (voting and non-voting) submit
quarterly projections for inflation, unemployment, and the federal funds rate among other variables.
There are at most 19 participant submissions for each of these meetings: 12 from the Federal Reserve
Bank presidents and 7 from the Board of Governors of the Federal Reserve System; to maintain
confidentiality of FOMC participants are not identified in these projections. Rather, participants are
assigned a number randomly and the number may change from meeting to meeting. The projection
horizon includes the current year and two additional years. During the last two meetings of each year,
participants extend their projections by one year. The multi-year character of this protocol yields as
many as 14 forecasts for a given year.
Participants’ projections are revised in response to economic developments. Further, the revisions
use information available through the conclusion of the meeting, on each participants’ assumptions
regarding a range of factors likely to affect economic outcomes, and on his or her assessment of
appropriate monetary policy. Importantly, forecasts revisions cannot be unambiguously interpreted as
reactions to news. As indicated earlier, FOMC participant projections depend on their assessments of
the appropriate monetary policy. Thus as participants’ terms expire, new participants will bring their
own assessment which then means different forecasts, even in the absence of economic news.
Since 2012, the FOMC has been releasing participant’s projections for the federal funds rate. For
inflation and unemployment, the FOMC has been releasing since 2007 the Ranges and Central
Tendencies of these projections. The FOMC also releases with a five year delay the individual
participant’s projections for inflation and unemployment:
17
Source: Marquez and Herrador (2016)
This peculiarity in FOMC data releases
means that the period with interest-rate
forecasts from individual participants does
not overlap with the period of inflation and
unemployment forecasts from individual
participants. Given the simultaneity of the
model, Marquez and Herrador (2016)
combine data from two types of releases
from the FOMC for meetings over the
period 2012-2015 (enclosed area): participant-specific projections for the federal funds rate and
bounds of projections for inflation and the unemployment rate. This database serves as the core for
this analysis.
For analytical purposes, denote 𝑖(,*,+ as the federal funds rate projection at time t (the date of the
FOMC meeting) by the 𝑗(- FOMC participant (𝑗 = 1…𝑛() for the 𝑦(- year (𝑦 = 2012…2018).
Note that the number of FOMC forecasts submitted at date𝑡, 𝑛(, might vary from meeting to meeting.
The mean of the participant’s projections for 𝑖 in year 𝑦 and meeting 𝑡 is:
𝑖(,+ =1𝑛(
𝑖(,*,+; 𝑛( ≤ 19=>

The following table shows how the data projections for the FFR are then assembled:
18
The vector of projections of the average federal funds rate in 2014 is:
𝑖AB@C = [𝑖*E=FAB@A,AB@C; … ; 𝑖GFHAB@A,AB@C]′
This vector has 11 entries because there were 11 meetings from June 2012 to December 2014
that included a projection for 2014; these observations are enclosed in a rectangle. Stacking the
vector of forecasts of average fed funds rate across all FOMC meetings yields:
𝑖 = [𝑖AB@A; 𝑖AB@K; 𝑖AB@C]′
For analytical purposes, adopt the following notation with regards to unemployment and
inflation forecasts:
𝜋(,+- : upper bound of the range of inflation forecasts in year y made during FOMC date t
𝜋(,+L : lower bound of the range of inflation forecasts in year y made during FOMC date t
𝑢(,+- : upper bound of the range of unemployment forecasts in year y made during FOMC date t

𝜋(M@OPQ SPF inflation forecast in year y made at time t-1
𝑢(M@OPQ SPF unemployment forecast in year y made at time t-1
19
The following table illustrates the alignment of forecasts and conditioning variables for 𝜋AB@A-
and 𝜋AB@K- . Note that when comparing FOMC forecasts with SPF forecast we always match the
latest available forecast for the same horizon prior to each meeting. The same goes for matching
actual information for unemployment and inflation (as obtained from the Fed’s FRED).
The observations enclosed by the rectangle emphasize the role of current information in
conditioning forecasts at different horizons. For example, the actual inflation rate as of October 2010
is being used in the November 2010 meeting as information to forecast the inflation for 2012 and
2013.
Previous work has been focused on a wide examination of multiple dependent variables including
individual SEP forecasts (where available), mean, median, central tendencies, and ranges. In this
particular, study I will focus primarily on the mean of the interest rate projections and the central
20
tendency midpoint (denoted with 𝑚𝑝 in the equations ahead) for the unemployment and inflation.
Doing this when looking at the entire sample from 2008 onwards would be misleading given the large
degree of variation of the level of consensus from meeting to meeting. However, for the period after
2012 the central tendencies for unemployment and inflation have been significantly tight making it
reasonable to proceed in this manner. (see Appendix 3)
In this extension of the Marquez and Herrador (2016) database I match the latest available prices
of the WTI price of crude oil and S&P 500 index with every observation. As a robustness check, I
also constructed a variable to measure the volatility of such prices. This took the standard deviation
of the time frame period in between each FOMC meeting.
7. Identification and Econometric Specification
The first postulated estimation model is:
𝑖(,+ = c + βWπX,YZP + β[uX,Y
ZP + εX^ (1)
Equation (1) assumes that the interest-rate forecasts depends on the mid-point of the forecast central
tendency distributions of inflation and unemployment forecasts. Ideally, we would like to use the
means of the distributions of participant’s projections for inflation and unemployment but the FOMC
has not released participant specific projections.
Alternatively, and as a measure of robustness we modify the previous model and substitute the FOMC
forecast with the SPF forecast and the actuals:
𝑖(,+ = c + βWπX,Y"#$ + β[uX,Y"#$ + εX"#$ (2)
𝑖(,+ = c + βWπX,YN + β[uX,YN + εXN (3)
Having understood the relationship between the three concepts we proceed to control for the
influence of external shocks and other control variables as follows:
𝑖(,+ = c + βWπX,YZP + β[uX,Y
ZP + β_ζX + κX + βb𝑋d,(d^?@ + εX
ZPeO-fHdO (4)
Where ζY represents the log level of the latest price of oil observed before the meeting, κY is an
additional unobservable shock and 𝑋d,+ is a vector containing a number of control variables as
observed at y.
21
Finally, another specification looks at the extent to which shocks to the price of oil interact with
inflation forecasts to affect the projection of future rates:
𝑖(,+ = c + βWπX,YZP + β[uX,Y
ZP + β_ζX + βW_πX,YZP · ζX + εX^=(FhNH(^f=O (5)
First we use simple OLS estimates (with robust standard errors) to run these specifications. Later we
control for concerns over the variance stationary nature of the variables in question by looking a the
first differenced equations and controlling for additional endogeneity by solving a simultaneous model
similar to FIML to serve as a robustness check.
In addition, we test for these specifications across different time periods. In particular and as expected,
we observe a big influence of ζY on 𝑖 for the period that only looks at projections made after 2014
when the oil price was movement were rather unexpected. Another robustness check is carried out by
including dummies that control for different forecast horizons.
8. Results Figure 9 (Full Sample 2012-present)
The table in figure 9 shows a variety of
regression specifications estimated over the entire
sample for which we have target rate forecasts.
Higher inflation projections are consistent
with an upward 1.4 ppt revision of the average
projection of the target rate for the same horizon.
This is point estimate is similar and significant
regardless if the forecast is made by the FOMC or
the SPF. Surprisingly, changes to today’s inflation
doesn’t seem to affect projections of future target
rates.
As expected, higher unemployment
projections are consistent with a downward 0.6
ppt revision of the average projection of the target rate for the same horizon. This is also true
regardless if the forecast is made by the FOMC or the SPF. Changes in today’s unemployment,
however, do seem to affect projections of future target rates.

The price of oil and changes to the S&P index have weak influence over target rate forecasts.
Now, lets look at the entire sample as we estimate
the coefficients of the first differenced equations. (Table
in Figure 10) In this case, these differences represent the
revisions for the projections and the changes to the price
of oil. The coefficients estimated in this model in
column 1, which only looks at inflation, unemployment,
and the target rate, are statistically insignificant.
However, in column 2, when also controlling for the
price of oil, both the log level of the price of oil and the
unemployment projection revision coefficient become
significant and have the expected sign and similar
magnitude to the previous result. This is remarkable because this specification includes the whole
period for which we have target rate projections.
Figure11(Recentsample2014-present)
The table in Figure 11 shows a variety of
regression specifications that were estimated on a
smaller but more recent sample which only looks at the
projections made starting in 2014.
Higher inflation projections are still consistent
with an upward revision of the average projection of
the target rate for the same horizon. This is true
regardless if the forecast is made by the FOMC or the
SPF. Changes to today’s inflation don’t seem to affect
projections of future target rates.
For this period not only are higher unemployment
projections consistent with a downward revision of the
average projection of the target rate but the participant’s assessment of future rates seems to be twice
as sensitive to changes in unemployment projections. This is also true regardless if the forecast is made

by the FOMC or the SPF. However, changes to today’s unemployment, continues not to affect
projections of future target rates.
More importantly, over this period changes to the price of an oil barrel have a strong influence
over target rate forecasts. A 10% decrease in the price of WTI has been associated with a 0.10ppts
downward revision for the Summary of Economic Projections (SEP) forecasts for all the horizons.
This is consistent with the narrative discussing the delay in the implied lift-off by the SEP.
In Appendix 4, I include further robustness checks both for the entire and recent samples. The
results are consistent even when controlling for multiple forecast horizons. Furthermore, the
relationship remains pretty much the same even when using at the central tendency low and high
bounds instead of the mid points as our explanatory variables. Finally, controlling for the 3-month
standard deviation of the price of oil does not change the results by much for either sample selection.
As a robustness check, Appendix 5 uses the PcGive statistical software to compute the coefficients
for the entire sample by solving for a simultaneous system of equations. The relationship between the
rates, unemployment and inflation remain similar to the first set of OLS results but the influence of
the price of oil is not captured in this model.
9. Understanding shifts in the distribution of SEP forecasts
Appendix 6 compares the distribution of the projections at the four different meetings that took
place in the years 2014 and 2015. The darker colors denote the projections that occurred in the most
recent meetings. What we see is that in 2014 the projections where evenly distributed around the mean
of the year forecasted. No one color is predominantly distributed either above or bellow the year’s
mean projections for each horizon. However, in 2015 we see that the darker colors are predominantly
bellow the lighter ones denoting that the projections shifted in a parallel manner across forecast
horizons as the year passed by. We clearly see the dark bars evenly concentrated bellow the mean for
all forecasts made in 2015.
24
Figure 12
Figure 12 summarizes this pattern by
showing how the ranges and mean of the
projections made in 2015 shifted down as
the price of WTI Oil continued to drop
throughout the year for every horizon level.

10. Concluding remarks
This study finds strong evidence for a consistent policy reaction function that can be derived
from the available information contained in the set of FOMC SEP forecasts. When looking at the
whole sample of target fund projections, a 1% upward revision in inflation projections tends to
increase target rate projections by about 0.6 to 1.5 ppts. Moreover, an upward revision in
unemployment projections is associated with a downward target rate revision of 0.6 to 1.5. The
unemployment coefficient estimate is higher when we restrict our analysis to a more recent sample
only considering the last 2 years of projections. This seems to suggest that the Fed may be more
sensitive to changes in unemployment over changes in inflation as the economy moves away from the
ZLB.
For the recent sample, the influence of inflation projection on target fund projections can be
mostly attributed to the large drop in the price of a barrel of crude oil. In particular, this explains the
observed rate lift-off delay of 2014-15 since 10% decrease in the price of WTI was found to be
associated with a 0.10 percentage point downward revision for the target rate forecasts for all the
horizons. This unexpected exogenous shock shifted the timing of the policy schedule but not did not
affect projections about the pace at which the rate hike would occur.
Should the SEP provide a clear roadmap of non-ZLB policy decisions, as documented by
previous work, the rate hike is expected to be of about 1 percentage point per year over the next 3
years provided that the price and the unemployment levels remain close to current values. Although
the recent energy price shock gives us useful information about how FOMC target rate forecasts are
determined, it remains difficult to say anything about how the Fed’s response function will change to
unexpected changes to unemployment because since 2008 we have not experience any other
substantial shocks to the labor market.
11. Challenges to current work The main challenge of this work relates to the extent to which our data can be treated as a
representative sample of all past and future FOMC projections. In particular, our data is considerably
small and mostly covers the historically unprecedented long period where the Fed Funds Rate was
26
near zero. Since the target rate projection sample was only available after June 2012, we have less than
53 observations which may be a source of potential endogeneity especially because unemployment
has done nothing but drop since that date. As a result, we also don’t have enough information about
how the FOMC's target rate expectations could react to large shocks to the labor market. Moreover,
inflation has not been above the 2 percent target so we have yet to see how the SEP react in periods
of high inflation expectations.
Maybe it is the case that there isn’t much variation yet in the data to allow us to have enough
power to estimate the effect of the regressors on target rate projections. Moreover, this study may be
further challenged because it is not able to distinguish for asymmetric preferences, which may include
the possibility that the FOMC may have different postures for positive and negative shocks to either
labor market or the price level (ex. different ways of fighting inflation and deflation).
Since the period of study was characterized by tight central tendency bounds, it would be
difficult to assess whether these results hold true even if the the central tendency ranges were to be
much wider as they were before 2012. In general, forecast bounds might remain unchanged, along
with their mid-point, even though forecasts are being revised. Thus, it would be interesting to see if
in the future the results still hold even when there is further dispersion.
12. Further work First of all, more research needs to be conducted as more SEPs keep being released especially
now that the median statistics are also being released for unemployment and inflation projections,
starting since September 2015. It is also important to allow for vintage variations in both quantitative
and qualitative information. In particular, one could investigate how shocks to unemployment, energy
prices, and financial assets have been perceived in the past by incorporating text analysis measures of
the financial press, mining over social media, and using “Big Data” resources.
It may also be a good idea to study whether different series related to unemployment and
inflation contain any predictive power. In particular, more work needs to be conducted using different
measures of labor force participation, differentiating between unemployment in exportable and non-
exportable sectors, or maybe across different regions. One may also account for more nuanced
measures of policy objectives by relating the target rate to the state of the credit markets by looking at
27
the yield curve and the futures rate markets. Finally, other multiple breakdowns of the price level could
be explored by including changes to core-inflation, housing prices, wages, among others.
