Governor Jeb Bush on the Desired Trend in Real GDP

From Bloomberg, a quote from the Governor’s speech in Detroit:


… I don’t think the U.S. should settle for anything less than 4 percent growth a year–which is about twice our current average.



I applaud the Governor’s aspirations. Here is a plot of what real GDP would have looked like had we had 4% annual growth (log terms) since 1967Q1 (in red), and if we’d had it under the administration of G.W. Bush (green).

Bush administration) (green). Growth rates calculated as log differences. Source: BEA 2014Q4 advance release, and author’s calculations.


Well, if 500,000/month job creation is the norm (as Governor Mitt Romney asserted), why wouldn’t 4% growth be the norm? Just because it hasn’t happened yet, doesn’t mean it can’t.

Keystone XL Employment Effects

They’re small. Really small. From the Congressional Research Service (Jan. 5, 2015):


Because job projections, in particular, involve numerous assumptions and estimates, the State Department’s job estimates for Keystone XL have been a source of disagreement. One challenge to State’s analysis is that different definitions (e.g., for temporary jobs) and interpretations can lead to different numerical estimates and “fundamental confusion” about the Final EIS numbers. Consequently, it may be difficult to determine what overall economic and employment impacts may ultimately be attributable to the Keystone XL pipeline or to the various alternative transport scenarios if the pipeline is not constructed.



The CRS report quotes this portion of the State Department EIS:


During construction, proposed Project spending would support approximately 42,100 jobs (direct, indirect, and induced), and approximately $2 billion in earnings throughout the United States…. Construction of the proposed Project would contribute approximately $3.4 billion (or 0.02 percent) to the U.S. gross domestic product (GDP). The proposed Project would generate approximately 50 jobs during operations. Property tax revenue during operations would be substantial for many counties, with an increase of 10 percent or more in 17 of the 27 counties with proposed Project facilities. …


Additional clarification on what proportion of those jobs would be American, vs. foreign, sourced is from this Cornell report:


Based on jobs information provided by TransCanada for the FEIS, KXL US on-site construction and inspection creates only 5,060-9,250 person-years of employment (1 person-year = 1 person working full time for 1 year). This is equivalent to 2,500-4,650 jobs per year over two years. (page 7)


What about the materials used in the construction of the pipeline?


TransCanada claims that “the $7 billion (KXL) pipeline project is expected to directly create more than 20,000 high-wage manufacturing jobs and construction jobs in 2011-2012 across the Us, stimulating significant additional economic activity.”20 This claim is misleading and erroneous on a number of levels.

First, as discussed above, the budget for KXL US that relates to incremental US employment is $3 to $4 billion and not the $7 billion claimed by the proponents. Second, TransCanada and other KXL proponents are giving the impression that KXL will create a high number of manufacturing jobs. This is simply not true. The main manufacturing activity related to pipeline construction is the manufacture of the steel pipe. The 36-inch steel pipe is the largest single materials input for KXL. This is literally the pipe in the pipeline. In general, pipeline construction is not a manufacturing-intensive activity even if the steel itself is also being manufactured onshore.

This section will present strong evidence that:

(a) almost half (and perhaps more) of the primary material input for KXL—steel pipe—will not even be produced in the United States;

(b) based on the experience of Phases 1 and 2, the final processing work for KXL will probably be performed in the US with most of the steel and pipe sourced from oustide of the US (notably India and South Korea).21 (page 11)


Now, no doubt there will be some spillover effects (Note: If you didn’t believe in spillover/multiplier effects arising from the American Recovery and Reinvestment Act (ARRA), you won’t believe in any multiplier effects from Keystone XL construction.). Let’s assume there is such a thing as a spending multiplier; then using plausible estimates for incremental building, and accounting for imported inputs, the Cornell researchers conclude:


…the incremental US spending associated with KXL project construction is only about $3 to $4 billion. Given a multiplier of 11 person-years per $1 million, this translates into total employment impacts of 33,000 to 44,000 person-years.59 So a reasonable estimate of the

total incremental US jobs from KXL construction is about one-third of the figure estimated in the Perryman study and used by industry to advocate for the construction of KXL.

Moreover, any job impacts associated with KXL construction would be spread over 2 and more likely 3 years.60 So the annual impacts are at most about 22,000 person-years of employment per year, for two years.61 But the annual impacts could also be as low as 11,000 person-years per year, for three years.62 (page 24)


For context, the US economy added 252,000 to nonfarm payroll employment in December alone.

Economic Performance under Various Presidential Administrations

Lest people forget what happened in times past.



presidents_updated


Chart from Floyd Norris, “Economic Setbacks That Define the Bush Years,” NYT, 24 January 2009, updated through 12/2014. Data for debt through 2014Q3. Red lines denote performance under Obama, through 2014Q4.


The original version of this graph was originally included in this post.


Since the graph assumed -5% growth in 2008Q4 (SAAR), rather than the actual -8% realized, the G.W. Bush era average growth rates should be slightly smaller than graphed.


Notice that a couple of series were off the charts, at least in the scales provided: the SP500 has risen by 24% annually on average over the last six years. Gross debt to GDP is 101% as of 2014Q3. Note that Federal debt held by the public as a share of GDP is 72.6%, down from a peak of 74% in 2014Q1.


Average growth and average per capita growth tend to be higher in Democratic administrations. Alan Blinder and Mark W. Watson investigate why, in this paper. The authors conclude:


It seems we must look instead to several variables that are mostly “good luck.” Specifically, Democratic presidents have experienced, on average, better oil shocks than Republicans, a better legacy of (utilization-adjusted) productivity shocks, and more optimistic consumer expectations (as measured by the Michigan ICE).


One question that occurs to me: Why are economic actors more confident during Democratic administrations?

Another solid GDP report

The Bureau of Economic Analysis announced yesterday that U.S. real GDP grew at a 2.6% annual rate in the third quarter. Even factoring in the dismal start to the year, that leaves full-year GDP growth during 2014 at 2.4% (the best annual performance since 2010) and growth at an annual rate of 4% over the last 9 months.



U.S. real GDP growth at an annual rate, 1947:Q2-2014:Q4. Blue horizontal line is drawn at the historical average (3.1%).

Government spending had contributed 0.8 percentage points to the Q3 growth but subtracted 0.4 percentage points from Q4. Most of that swing can be attributed to a one-time bulge in defense spending in Q3. But the biggest reason for slower GDP growth in Q4 than in Q3 was the fact that real imports grew by 8.5% (at a continuously compounded rate) in the fourth quarter. Since imports are subtracted from GDP, more imports mean less GDP.


gdp_components_jan_15


It’s worth noting that although real imports increased by 8.5% at an annual rate, the nominal value (that is, the actual number of dollars spent on imports) was only up 0.9% at an annual rate. The big story was not simply that we’re importing more barrels of oil than expected for this time of year, but that each barrel of imported oil cost us fewer dollars. That means that the apparent surge in real imports is less of a long-run burden for the U.S. than might appear at first glance from the data, and the underlying situation is reasonably healthy.


Fixed investment remains disappointing. But as Bill McBride notes, there’s still lots of room for growth there and reasonable basis for expecting it’s still to come. Residential fixed investment is still way below normal when expressed as a percentage of GDP– added confirmation of Reinhart and Rogoff’s observation that recovery from an event like the U.S. has gone through takes a long time. Once housing makes a decent recovery, we might expect business plant and equipment and structures to follow.

Our Econbrowser Recession Indicator Index, which uses ysterday’s data release to form a picture of where the economy stood as of the end of 2014:Q3, is now all the way down to 1.6%, an unambiguous signal of an ongoing recovery.

The plotted value for each date is based solely on information as it would have been publicly available and reported as of one quarter after the indicated date, with 2014:Q3 the last date shown on the graph. Shaded regions represent the NBER's dates for recessions, which dates were not used in any way in constructing the index, and which were sometimes not reported until two years after the date.

Some Observations on the 2014Q4 GDP Release

The external sector weighs in, and thinking about the length of the recovery.



First note the contribution of exports and imports to growth (in an accounting sense), in percentage points.


growthcontrib15


Figure 1: Contributions to real GDP growth, in percentage points of imports (green), exports (red), and all else (blue), all SAAR. Source: BEA 2014Q4 advance release, and author’s calculations.


Instead of having an essentially net zero impact in the third quarter, import growth contributed -1.4 percentage points (annualized). To the extent that the higher growth in imports represents greater consumption in anticipation of a sustained recovery, the news is good. The slowdown in export growth is not helpful, on the other hand. The evolution of real exports and imports is shown in Figure 2.


exportsimports


Figure 2: Log real exports (blue), imports (red), and imports ex.-oil (green), all SAAR, bn. Ch.09$. Source: BEA 2014Q4 advance release, and author’s calculations.


Some of this is due to an appreciated dollar; I read a lot about the impact of the stronger dollar, but it’s important to keep in context the appreciation thus far.

realdollar


Figure 3: Log real value of the US dollar, against a broad basket of currencies, 1973M03=0. Note 2014Q4 observation is average of October and November. Source: Federal Reserve Board via FRED, author’s calculations.


So, in the absence of a continued substantial appreciation, one shouldn’t worry about the recovery being derailed on this account alone — unless US goods have become much more substitutable for foreign in the past fifteen odd years. That could be the case. (More here).


On the other hand, Deutsche Bank, in its forecasts released today, argues the dollar is only halfway through its appreciation from the July 2011 trough (FX Forecasts and Valuations, January 30, 2015).

Hence, I do think that the Fed should take into account external developments. To the extent that expansionary monetary policy in the Eurozone and Japan put upward pressure on the dollar’s value, it doesn’t seem problematic to counter that effect by going slow on tightening monetary policy. This is particularly true given the absence of inflationary pressure in headline inflation, and modest growth in labor compensation as indicated in todays productivity and costs release.


The other observation I have on the GDP release pertains to the length of the recovery. The last recession ended, by the NBER’s reckoning, in June 2009. That means that by the end of 2014 (assuming a recession had not already begun), the recovery has now lasted 66 months. To place this in perspective, I show the length of the current recovery in a graph from an article in the Economist nearly two years ago.


reclength_chinn


Figure 4: Graph, adapted from “Business Cycles: Running out of Time?” Economist (January 2013).


What the (updated) graph shows is that by the standards of post-1982 recoveries, this recovery has not yet matched the duration of an average recovery. Hence, some (but by no means all) of the anxieties expressed in the Economist article have been allayed.


Now, this is a somewhat mechanistic way of thinking about recovery duration. One should also think about shocks from abroad (Euro area, China), but without knowing if and when such shocks might strike, then one can think about what usually ends a recovery — and there it often seems to be a tightening of monetary policy. That’s yet another reason to worry about over-eagerness in tightening, especially as the dollar appreciates.


Fortunately, for now, the yield curve is not signaling a recession in the next year [1].

More on U.S. Employment, Post-Trough

Reader rtd states “it is virtually guaranteed that after a nation’s business cycle trough, that same nation’s employment growth will display an upward trend.” I thought this an interesting enough assertion that it merited additional investigation.



If one were looking at data in the US from the beginning of the nonfarm payroll series until the 1990-91 recession, this characterization would be apt, as shown in Figure 1.


earlyrecessions


Figure 1: Log nonfarm payroll employment (blue). NBER defined recession dates shaded gray. Long dashed line at end of WWII. Source: BLS via FRED, NBER and author’s calculations.


Employment rises almost immediately after the NBER defined troughs. Inspection of the recessions since 1990-91 exhibit a much different behavior. (On a side note, notice that employment declines with end of the war, with recession ending at 1945M10.)


Now compare the behavior of nonfarm payroll employment after troughs of the last three recessions. There is a much delayed resumption of employment growth, as shown in Figures 2-4.

On a side note, a similar delay (and smaller rebound) is apparent in Eurozone employment, as discussed in this post. In the UK, employment only exceeds the 2009Q3 level (end of the recession) in 2010Q2.

Implications for Economic Growth of Governor Walker’s Proposed Higher-Ed Funding Cuts

From Foxnews:


Wisconsin Gov. Scott Walker is calling for steep cuts to the University of Wisconsin System, while offering the network more freedom in exchange, … [H]is university plan … would cut funding by $300 million over two years…



This measure would amount to a 13% cut in state funding to the university system. In addition, the Governor’s proposal includes a continued tuition freeze until 2017, until which time tuition changes would be unconstrained. That means under the Governor’s plan, funding levels would be reduced, while the university is stopped from raising revenues. Layoffs seem plausible. [1]


I find this approach to dealing with the state’s calamitous fiscal situation (exacerbated by recent ill-advised tax cuts) interesting to the extent that higher education is important to economic growth. From KNOWLEDGE MATTERS: THE LONG-RUN DETERMINANTS OF STATE INCOME GROWTH, in the Journal of Regional Science (2012):


A state’s knowledge stocks (as measured by its stock of patents and its high school and college attainment rates) are the main factors explaining a state’s relative per capita personal income.

We find that these effects are robust to a wide variety of perturbations to the model. Other things equal, being one standard deviation above the states’ average in the stock of patents per capita (75 percent higher) leads to 3.0 percent higher per capita personal income. Similarly, being one standard deviation above the states’ average in high school attainment (a 20 percentage point increase) leads to 1.5 percent higher per capita personal income. Finally, being one standard deviation above the states’ average in college attainment (23 percentage points higher) leads to 1.4 percent higher per capita personal income.


In short, we find that incomes have failed to converge because knowledge stocks have failed to converge. If state policymakers want to improve their state’s economic performance, then they should concentrate on effective ways of boosting their stock of knowledge.


By this criterion, the Governor’s plan is counterproductive.

What’s driving the price of oil down?

In December I provided some simple calculations of the extent to which a slowdown in the growth of global oil demand may have contributed to the spectacular drop in oil prices since last summer, and I updated those estimates two weeks ago. Some of you have suggested that as conditions keep changing, perhaps I should update those calculations every week. Thanks to the always-helpful Ironman at Political Calculations, I can now go that a step better, and provide eager Econbrowser readers a quick tool they can use to update these calculations on their own on a daily basis, if your heart so desires.




The basic idea behind my calculations is the observation that at the same time that oil price has been declining, we’ve also observed big drops in the price of other commodities like copper, the yield on 10-year U.S. Treasuries, and the value of other currencies relative to the dollar. My assumption is that the success of oil producers in Texas has little to do with the latter three developments.


I used a regression estimated using weekly data from April 2007 to June 2014 to summarize the historical correlation between changes in the price of oil and changes in the other three factors. I used the coefficients from that regression to calculate how much of the change in the price of oil in each week since July could have been predicted statistically on the basis solely of changes in copper prices, bond yields, and the value of the dollar, interpreting those predicted values as the fraction of the oil price change that might be reflecting broader weakness of the global economy as opposed to any specific development in oil markets in particular.



Ironman has put together a little tool you can use to calculate how much of the change in the price of oil between any two dates would be attributed to demand factors with this method. Just input the four prices at your chosen starting date and ending date and press calculate. It’s set up with default values (if you just press “calculate” yourself without entering any numbers) to analyze the change in the price of oil between July 4 and January 15. If you try it you’ll see the answer is that oil prices would have been expected to fall to $75 a barrel based on changes in demand factors alone since last summer, accounting for a little more than half of the observed decline in the price of oil.

I’ve also provided little self-updating widgets below that should always display the very latest values of these indicators. So you could come back to this page any time in the future, enter the values you see displayed below in the “current values” boxes and see how any new developments may have changed the calculations.







Commodities are powered by Investing.com


And I also provide below a table with the historical weekly values for the variables since every date this summer, if you are interested in how much of the change since a given date might be attributed to demand factors. For example, if you input starting values as of December 12, you’ll see that 68.8% of the change between December 12 and January 15 appears related to developments affecting global markets generally and not just oil.


In other words, increases in oil supply have been very important, but many analysts seem to be overlooking a critical part of the story.


Thanks again to Ironman for letting us use his neat tool.

Quasi-Stylized Facts about Employment after Troughs

Reader rtd writes: “…it is virtually guaranteed that after a nation’s business cycle trough, that same nation’s employment growth will display an upward trend”, but when asked about the euro area, argues “The Eurozone is a conglomerate of nations with varying fiscal policies, ideologies, cultures, and the list goes on and on. Please don’t compare apples with hand grenades.”



So here is the case where employment does not rise relative to trough.

Inspection of US data indicates that employment falls for some time after the trough in the last three recoveries. That’s where the term “jobless recoveries” comes from.


Update, 9pm Pacific: Here is a close-up on US employment trends after the 2001M11 trough.
