Nebraska Monthly Economic Indicators: June 21, 2017 Prepared by the UNL College of Business Administration, Bureau of Business Research Author: Dr. Eric Thompson Leading Economic Indicator...1 Coincident Economic Indicator. 3 Weights and Component Shares. 5 Performance of the LEI-N and CEI-N. 6 Summary: The Leading Economic Indicator Nebraska (LEI-N) 1 fell by 0.51% during May of 2017. This is the second consecutive monthly decline in the LEI-N. The declines followed three months of rapid increase from January through March of 2017. Taken together, the LEI-N values imply a moderation in economic growth in Nebraska in late 2017 after strong growth midyear. Among the components of the indicator, business expectations were strong during May while the value of the U.S. dollar fell, which is a positive sign for Nebraska s export-oriented businesses. However, manufacturing hours, building permits and airline passenger counts all declined during May, while initial claims for unemployment insurance rose. Leading Economic Indicator Nebraska Figure 1 shows the change in the Leading Economic Indicator Nebraska (LEI-N) during compared to the previous month. The LEI-N predicts economic growth six months into the future. The LEI-N fell by 0.51% in May. 2.46% 1.23% Figure 1: Change in LEI-N Rapid Growth Moderate Growth -1.23% -2.46% Moderate Decline Rapid Decline -0.51% Figure 2 shows the change in the LEI-N over the last six months. The indicator increased sharply during the first quarter of 2017 but fell in April and May. Indicator values over the last six months suggest that economic activity will accelerate in Nebraska during the summer of 2017 but growth will moderate at the end of the year. 1 The author would like to thank Dr. William Walstad for helping to design the LEI-N. 1

The change in the overall LEI N is the weighted average of changes in each component (see page 5). Four of the six components of the LEI-N declined during May. There was a decline in building permits, airline passenger counts and manufacturing hours on a seasonally adjusted basis. Initial claims for unemployment insurance also rose during May, signaling a softening of the labor market. However, two components of the LEI-N were positive in May. Business expectations were very strong. Respondents to the May Survey of Nebraska Business predicted strong growth in both sales and employment at their businesses over the next six months. In addition, the value of the U.S. dollar fell modestly during May, a positive development for Nebraska s export-oriented businesses. Note that the trend adjustment component pictured in Figure 3 is discussed on page 5. Figure 3: LEI-N Components of Change 2.46% 1.23% -1.23% -2.46% -0.08% -0.29% 0.10% -0.96% -0.18% 0.80% 0.10% 2
Coincident Economic Indicator Nebraska The Coincident Economic Indicator - Nebraska (CEI-N) is a measure of the current size of the Nebraska economy. The CEI-N rose by 0.32% during, as seen in Figure 4. 2.56% Figure 4: Change in CEI-N Rapid Growth 1.28% -1.28% -2.56% Moderate Growth Moderate Decline Rapid Decline 0.32% Figure 5 shows the change in the CEI-N over the last 6 months. Economic conditions appear to be improving in Nebraska. The indicator has risen during each of the last three months. Figure 5: Change in CEI-N Last 6 Months 2.56% 1.28% 1.86% 1.05% 1.57% 0.32% -1.28% -0.54% -0.67% -2.56% Dec 16 Jan 17 Feb 17 Mar 17 Apr 17 May 17 Three components contributed to the increase in the CEI-N rose during May (Figure 6). Agricultural commodity prices improved during May, especially prices for cattle. Business conditions also were positive, with respondents to the May Survey of Nebraska Business reporting that employment rose at their businesses in recent months. Further, electricity sales increased after adjusting for weather and seasonality. Real private wages were the only declining component, dropping after a sharp increase during April. A detailed discussion of the components of the CEI-N and LEI-N can be found at www.cba.unl.edu in Technical Report: Coincident and Leading Economic Indicators- Nebraska. 3

Growth is expected to be strong during the summer but tepid during the fourth quarter of the year. These expectations are consistent with the first quarter increases in the value of the LEI-N as well as its April and May decline (Figure 2). 1.30% 0.80% 0.30% -0.20% -0.70% -1.20% -1.70% Figure 7: 6-Month Forecast of Coincident Economic Indicator - Nebraska 0.17% 1.40% 0.82% -0.05% -0.34% 0.18% May 17 Jun 17 Jul 17 Aug 17 Sep 17 Oct 17 Nov 17 123.00 122.00 121.00 120.00 119.00 118.00 117.00 Index Growth Index Value 4
Weights and Component Shares Table 1 shows the weights used to aggregate the individual components into the LEI-N and CEI-N. The weights are the inverse of the standardized standard deviation of each component variable. The term standardized simply means that the inverse standard deviations are adjusted proportionately to sum to 1. This weighting scheme makes sense since individual components that are more stable have smaller standard deviations, and therefore, a larger inverse standard deviation. A large movement in a typically stable economic series would provide a more powerful signal of economic change than a large movement in a series that regularly has large movements.

Weights (from Table 1) are multiplied by the change to calculate the contribution of each component. Contributions are converted to percentage terms and summed. Note that in Table 2 a trend adjustment factor is utilized in calculating LEI-N. This is done because LEI-N historically under-predicts CEI-N by 0.10% per month. The U.S. Leading Economic Indicator also has a trend adjustment.

Figure 8 shows the value of CEI-N and the real gross state product (real GDP) in Nebraska for 2001 through 2016. Annual real gross state product data is provided by the Bureau of Economic Analysis, U.S. Department of Commerce, and quarterly values were estimated using quarterly earnings data. CEI-N closely tracks Nebraska real GDP for the period. The correlation coefficient between the two pictured series is 0.95. 130.00 125.00 120.00 115.00 110.00 105.00 100.00 95.00 90.00 85.00 80.00 Figure 8: Coincident Economic Indicator - Nebraska Comparison with Nebraska Real Quarterly GDP Figure 9 again shows the values for the CEI-N. It also graphs 6-months forward values for the LEI-N. Recall that the LEI-N is intended to forecast the Nebraska economy six months into the future. This implies that Figure 9 is comparing the predicted movement in CEI-N (predicted by LEI-N values six months earlier) with the actual movement in CEI-N. In Figure 9, predicted values using the LEI-N closely track trends and movement in the CEI-N. The correlation coefficient between CEI-N and six-month forward values of LEI-N is 0.91.
