Introduction
Standard macroeconomics textbooks consider capital and labor as inputs intheir production functions, but not energy.1 However, in the aftermath of thefirst energy crisis of the 1970s, economists began to pay greater attention to en-
ergy. Energy does not appear explicitly on the payments side of national accounts.
The payments to energy is equated to revenues of certain industries, such as
coal mining, petroleum and gas drilling (and value added in refining), and elec-
tricity generation and distribution. Using this approximation, it turns out that
energys share of payments in industrial countries is negligibleaccounting, in
most cases, to not more than a few percentage points of a nations gross domestic
product (GDP). Most economists in the past have assumed that energy could not
be very productive relative to the traditional variables of capital or labor,
depending on the income allocation theorem. To address this dilemma, it was
assumed that energy is an intermediate product of the economy. Thus, capital and
labor produces the output and energy serves an intermediate role as it is converted

provided a basis for the outgrowth of causality researchboth in its expansion and
diversificationinto other fields of causality research. The main findings of these
studies are determined with causality methodology. The results obtained are dif-
ferentiated based upon the direction of causality, which can be evaluated under
four hypotheses. First is the neutrality hypothesis, which assumes that no
causality exists between GDP and energy (electricity) consumption; therefore,
the energy (electricity) consumption is not correlated with GDP. Second is the
conservation hypothesis, which assumes that a uni-directional causality exists
that runs from GDP to energy (electricity) consumption. Third is the growth
hypothesis, which assumes that there is a uni-directional causality that runs from
energy (electricity) consumption to GDP. Last, we have the feedback hypothe-
sis, which assumes the existence of a bi-directional causality flow between GDP
and energy (electricity) consumption.
Thus, the energy causality literature is prolific (table 1)the relationship being
investigated by different studies, for various countries, over numerous time
frames. Despite the use of the very same variables, the end results offered different
coefficients and causality relationshipseven in the studies for the same coun-
tries. Econometric techniques, the structure of time series, and the business cycle
of the case countries studied may be the cause of obtaining different results for the
same nations. The most important point is the nonlinear structure of the economic
time series particularly as GDP, which has been used as the measure of economic
performance, fluctuates with the business cycles. With respect to energy eco-nomics, these models assume parameters to be constant over the sample period,
which means the relationship between GDP and energy consumption is stable. Of
course, this assumption of stability is not very reflective of the real world eco-
nomic situation during the past decades as can be witnessed by a significant
number of economic crises and meltdowns: the energy crises (1974, 1979), the
Exchange Rate Mechanism (ERM) crisis, the southeast Asia crisis of the 1990s,
the Great Recession of 2008, along with national-level crises. Clearly, the business
cycle affects the relationship between GDP and energy or electricity consumption.
In time-series analysis, the phase of the business cycle must be taken into account;otherwise, the estimated parameters would be incorrect and misleading.
One way to overcome these problems is to divide the sample into sub-samples,
based on the structural breaks; however, in most cases the exact dates of these
changes are not known and the researcher must determine them endogenously
based upon the data. But there is no guarantee that the relationship between GDP
and energy consumption changes at the same time as the break dates of the var-
iables themselves.10
J. D. Hamilton proposed a simple nonlinear framework for modeling economic
time series with a permanent component and a cyclical component as an alter-native to a stationary linear autoregressive model.11 M. Clements and H. Krolzig,

T. Bakrtasx used Markov-Switching Autoregression (MS-AR) and Markov-
Switching Vector Autoregression (MS-VAR) models to test the impact of oil
shocks on GDP.12 F. Falahi and M. Bildirici used the MS-VAR model to assess the
relationship between energy consumption and economic growth.13
In this paper, the MS-VAR model is selected to analyze the relationship be-
tween energy consumption and economic growth. Although this study can be
defined as complementary to the previous empirical papers, it differs from the
existing literature in some respects. First, it is distinguished from the previous
works as it employs the Markov-Switching VAR method. Second, it uses the
Markov-Switching Granger (MS-Granger) causality analysis. The MS-Granger
causality approach allows for the analysis of Granger causality under different
regimes of the business cycle.
This article is laid out as follows: the econometric theory and methodology are
identified in the second section. The third section consists of the empirical results
while the last section includes conclusions and policy implications.
Data and Methodology
Data: In this study, the relationship between energy consumption (EC), which is
taken asLEC= log(ECt/ECt-1), and economic growth (Y), which is represented as
LY= log(Yt/Yt-1), is investigated by the MS-VAR method. This study examines all
G7 countries, which represent seven of the eight wealthiest nations on earth (China
excluded), not by GDP but by global net wealth. The G7 countriesand our case
studiesare Canada, France, Germany, Italy, Japan, the United States, and the
United Kingdom, which we evaluate for the period from 1961 to 2011 (1970 to
2011 for Germany). The data are taken from GAPMINDER, the International
Energy Agency (IEA), the Organization for Economic Cooperation and De-
velopment (OECD), and the U.S. Energy Information Administration (EIA).
MethodologyMS-VAR Analysis: The MSI(.)-VAR(.) model is given as:
yt= m st Xq
k= 0Ai st yt1+ ut;
1
whereut/st;NID(0, S(st)) andAi(.) show the coefficients of the lagged values of
the variable in different regimes, andS shows the variance of the residuals in each
regime. m(st) defines the dependence of the mean m of the K-dimensional time
series vector on the regime variablest.
In an MS-VAR model, stis governed by a Markov chain and
Pr stj st1f g
i = 1; yt1f g
i = 1 =Pr stjst1; rf g; 2
where P includes the probability parameters. That is, the state in periodtwoulddepend only on the state in periodt1. On the other hand, the conditional prob-
ability distribution ofytis independent ofst-1, that is, P(ytjYt-1, St-1) = Pr(ytjYt-1).

The Markov chain is ergodic and irreducible; a two-state Markov chain with
transition probabilitiespijhas an unconditional distribution given by
Pr st= 1 = 1p22
2p11p22;Pr st= 2 =
1p11
2p11p22:
There are different ways to estimate the MS models, such as the maximum
likelihood estimate (MLE) and the expectation maximization (EM) suggested by
J. D. Hamilton. The EM algorithm has been designed to estimate the parameters of
a model where the observed time series depends on an unobserved or a hidden
stochastic variable. The iterative method was utilized with t = 1, 2,., T, while
taking the previous value of this probability jit1= Pr[st-1= ijWt-1;u] as an input.
MethodologyThe MS-Granger Causality Analysis: A. Warne and Z. Psaradakis
et al. proposed a different approach to causality based on Granger causality.14
F. Falahi utilized short-run or weak Granger causalities for MSIA(.)-VAR(.) models
by following the Granger causality in the context of Markov switching.15
Based on the coefficients of the lagged values ofLYtandLECtin the equations,
we could determine the existence of causalities between these two variables. In the
equation vector where the dependent variable is LECt, if any of the coefficients of
lagged variables of LYt are statistically different from zero, the obtained test
process will result in the acceptance of the causality. In any of the regimes, basedon the coefficients of the lagged values ofLYtandLECtin the equation forLECtandLYt, we could determine the existence of nonlinear causality between these
two variables. In the equation forLECt, if any of the coefficients ofLYtare sig-
nificantly different from zero in any of the regimes, then:
LYtLECt

k= 1

It is concluded thatLYt(LECt) is a Granger cause ofLECt(LYt) in that regime.
Granger causalities are detected by testing H0:f12(k)= 0 andH0:f21
(k)= 0.16

The methodology requires the estimation of either an MSIA(.)VAR(.) or an
MSIAH(.)VAR (.) model.
Empirical Results
For the determination of the LYandLECintegration order, in this study we
utilized the point optimal tests of both G. Elliott et al. and of S. Ng and P. Perron.17
The results from the unit root tests are presented in table 2. According to the result
in table 2, the first difference ofLYandLECappear to be stationary. After the unit
root test, the Johansen procedure was used to determine the possible existence of
cointegration between LECandLY. The Johansen cointegration result in table 2
determined that the null hypothesis of no cointegration was not rejected. If thevariables are not cointegrated, the first difference or innovations of their variables,
DLYandDLEC, can be used to test for MS-Granger causality.
MSIA(.)VAR(.) models were selected for Canada, France, Italy, and the
United States; MSIAH(.)VAR(.) models were used for Germany, Japan, and
United Kingdom. MS models were selected based on the Akaike Information
Criteria (AIC) and LR test. In selected models, in order to determine the number of
regimes, a linear VAR is first tested against a MS-VAR with two regimes; theH0hypothesis, which hypothesizes linearity, was rejected by using the LR test sta-
tistics. Since it was observed that the two-regime models were insufficient inoverruling the linear model in explaining the relationships between the chosen
variables, three-regime models were considered next. A MS-VAR model with two

16/31
For the MS-VAR models selected, the periods of economic expansion (rep-
resented by regime 2 and regime 3) had a longer time duration than the duration of
the recessionary period (regime 1), which was expected. Thus, the asymmetry
between periods of expansion and recession can be understood based upon the
differences in length of time.
The transition probability matrix is ergodic and cannot be irreducible. The
ergodic transition probability matrix confirms stationarity of the regime. As is
discussed in greater detail in the works of J. D. Hamilton and R. Gallager, the
ergodic transition probabilities matrix is always covariance-stationary.18
The Business Cycle Characteristic: Table 3 shows the business cycle dates im-
plied by the Markov-switching model as well as those provided by the Economic
Cycle Research Institute (ECRI) for the sample countries. To determine how well
the estimated models perform in business cycle dating, a measure of coincidencewas used, which was put forth by F. Canova et al. and S. Altug and M. Bildirici to
calculate the number of instances in which our peak or trough dates are plus or
minus one (two) quarters away from the ECRI dates.19
Thus, allowing for a maximum discrepancy of two (three) quarters, the average
coincidence between model dating and ECRI dating for the selected countries is
82.57 percent.
Regime 1 is a recession or crisis regime, regime 2 the moderate growth regime,
and regime 3 is the high growth regime. The persistence of regimes changes from
country to country in this study. The models track fairly well the oil crisis of 19741975 (the first oil recession), 19791980 (the second oil recession), 19891991,
and the recent 2008 crisis (see table 3).
In the estimated MS-VAR models, the total length of time for the expansion
period (regime 2 and regime 3) is longer than the length of time for the recession
(regime 1), as one would expect. The results indicated the presence of significant
levels of asymmetries for the business cycles experienced by the countries ana-
lyzed in this research.
For the first modeled country, the MSIA(3)VAR(1) model is estimated for
Canada and the results are given in table 4. The first regime tends to last 2.03 years
on average, while regime 2 is comparatively more persistent with a duration of
4.57 years. Finally, regime 3which corresponds to the high growth period
tends to last 11.33 years on the average. The moderate growth regime is the most
persistent regime in Canadas economy. The computed probability of Prob(st =
3jst1 = 1) = 0.102 reflects the probability that a recession is to be followed bya period of high growth. Further, as the calculated regime probabilities are Prob(st=
1jst1 = 1) = 0.5063, Prob(st = 2jst1 = 2) = 0.7811, and Prob(st = 3jst1 = 3) =0.9018, the persistence of each regime is significantly high. Based upon our re-
sults, we witness the presence of important asymmetries in the Canadian business
cycle.

For our next G7 nation, France, the results of the MSIA(3)VAR(4) model
are presented in table 5. The transition probabilities, Prob(st = 1jst1 = 1) =0.6220, Prob(st = 2jst1 = 2) = 0.8305, and Prob(st = 3js t1 = 3) = 0.7952, de-
termine the persistence of the high growth regime (regime 3). For France, themoderate growth regime has the longest duration (8.68 years), followed by
the high growth (7.87 years) and then the recessionary regime (4.7 years). The

Prob(st = 2jst1 = 1) = 0.2156 and Prob(st = 3jst1 = 1) = 0.1624 show the pos-sibilities of a recession being followed by a period of moderate and high growth,
respectively.
In the case of Germany, the MSIAH(3)VAR(1) model implies important re-
sults for the country, which are given in table 6. The result of Prob(s t= 1jst1= 1) =0.5735, Prob(st= 2jst1= 2) = 0.8607, and Prob(st= 3jst1= 3) = 0.7015 indicatethe persistence of the regimes. The ergodic probabilities point to regime 2 as being
the most dominant. Germanys transition probabilities; p11= 0.2456, p22= 0.5663,
and p33= 0.1881, highlight significant asymmetries in the nations business cycle.
The moderate growth phase is the most dominant in terms of duration lasting an
average of 7.74 years in comparison to the recessionary phase (1.90 years on
average) and the high growth phase (3.85 years on average). The computed
probabilities indicate that there is a higher probability that the German economy
goes from a crisis/recessionary phase into a moderate economic growth regime
(Prob(st= 2jst1= 1) = 0.2980) than into a high economic growth regime (Prob(st=3jst1= 1) = 0.1285).
The model selected for Japan is a MSIAH(3)VAR(4) and the results are
provided in table 7. Regime probabilities are calculated as Prob(st= 1jst1= 1) =0.6196, Prob(st = 2jst-1 = 2) = 0.8066, and Prob(st = 3jst1 = 3) = 0.7404, whichsuggest the persistence and dominance of the moderate growth regime (regime 2).
The high growth period tends to last 3.85 years on average, the crisis/recessionary
period lasts an average of 2.63 years, while the moderate growth regime has an
average duration of 5.17 years. The computed probability Prob(s t= 3jst-1 =1) =0.1566 reflects the chances that a recession is followed by a period of high growth;on the other hand, the computed probability Prob(st= 2jst1= 1) = 0.2237 indicatesa slighting higher probability that a recession is followed by a period of moderate
growth (regime 2).
The results obtained for Italy are reported in table 8. A MSIA(3)VAR(1)
model provided the best econometric performance. The transition probabilities,
Prob(st= 1jst1= 1) =0.6404, Prob(st= 2jst1= 2) = 0.7889, and Prob(st= 3jst1=3) = 0.8115, suggest the persistence of the high growth regime. The moderate
growth phase (regime 2) was found to last on average 4.97 years, while the highgrowth phase (regime 3) had a higher average duration of 5.48 years. Regime 2
was found to be the most dominant based upon the ergodic probabilities. As is the

In table 5 of the estimated MSIA(3)VAR(4) model for France, all coefficients
are statistically significant at the conventional significance levels. The estimated
coefficients of energy consumption innovations (DLEC) and economic growth
innovations (DLY) are statistically significant in the first regime, second, and thirdregimes. Some evidence of bi-directional Granger causality was found between
energy consumption and GDP in all regimes for France. In the first equation (the

equation of LY) for all three regimes, the EC appears to be the Granger cause of
economic growth. It is determined that Granger causality exists from EC to Y for
equation 1 in the first, second, and third regimes. According to the second equation
obtained for all three regimes, Y appears to be the Granger cause of energy
consumption and the direction of causality is from LY to EC for equation 2. Thus,
we found some evidence of bi-directional Granger causality between energy
consumption and GDP in the recessionary, moderate growth, and high growth
periods for France.
For Germany, the estimated coefficients of DLY and DLEC in the MSIAH(3)
VAR(1) model are statistically significant at conventional levels (table 6). The
coefficient estimates of DLEC in equation 1 are positive for all three regimes;
however, the coefficient estimates of DLY in equation 2 are negative for regimes 1
and 3. The results of equation 1 for all three regimes indicate that energy con-
sumption is the Granger cause of GDP. According to the second equation, that is,
the equation for LEC, GDP appears to be the Granger cause of energy consumption
for all three regimes. The evidence suggests that a bi-directional Granger causalityrelationship exists between energy consumption and GDP for Germany.
For Japan, the results for the selected MSIAH(3)VAR(4) model are reported
in table 7. The estimated coefficients of energy consumption innovations (DLEC)
for equation 1 in regime 1 are very high with a number around 3 for DLECt-2,
approximately 2.7 for DLECt-3, and around 1.1 for DLECt-4; they are statistically
significant and show that energy consumption is the Granger cause of GDP. In the
second equation, the GDP appears to be the Granger cause of energy consumption
in the first and second regimes. For equation 2 and in regime 3, the coefficients of
DLY are statistically insignificant. Thus, GDP is not found to have a Grangercausality relationship with EC in regime 3 (the high growth regime). To sum up
the findings on Japan, we found a bi-directional Granger causality relationship
existing between energy consumption and GDP.
The MSIA(3)VAR(1) model presented the best econometric performance for
Italy, with results given in table 8. The estimated coefficients of energy con-
sumption innovations (DLEC) in equation 1 are significant in the first, second, and
third regimes. The DLY coefficients in equation 2 of all regimes are statistically
significant at conventional levels. The results suggest evidence of Granger cau-
sality from EC to Y and from Y to EC. In the first equation (the DLY equation) inall of the regimes, the EC is determined to be the Granger cause of economic
growth. For the second equation (the DLEC equation) in all of the regimes, the LY

is determined to be the Granger cause of energy consumption. Thus, for Italy theresults point to bi-directional causality between EC and GDP in all regimes.
For United Kingdom, a MSIAH(3)VAR(4) was accepted as the best model (see
table 9). The estimated coefficients of the innovations for the energy consumption
(DLEC) are statistically significant in equation 1 for the first, second, and third re-
gimes. The DLY coefficients are statistically significant at the conventional signifi-
cance levels in equation 2 for all regimes. In the first equation in all regimes, the EC is
determined to be the Granger cause of economic growth. The LY appeared to be the
Granger cause of energy consumption in the second equations for all of the regimes.
In the MSIA(3)VAR(3) model for the United States, the estimated coefficientsof energy consumption innovations (DLEC) in equation 1 are statistically signifi-
cant at conventional level in all regimes (table 10). The parameter estimates of EC
in equation 1 of regimes 1 and 3 are negative. According to the first equation, GDP
appears to be the Granger cause of energy consumption in all regimes, and GDP is
found to be the Granger cause of energy consumption in the second equation in all
regimes evaluated. To conclude, we found some evidence of bi-directional Granger
causality between energy consumption and GDP for the United States.

relationship between energy consumption and economic growth, different results
will be obtained. There is evidence that supports the growth hypothesis for Italy,
Japan, and the United States. There is a uni-directional relationship from energy
consumption to real GDP, which means that energy consumption acts as a stimulus to
economic growth. The conservation hypothesis is suggested by our findings for Canada
and France. The conservation hypothesis is supported if an increase in Y causes an
increase in EC. There is evidence to support the neutrality hypothesis for Germany and
the United Kingdom. When comparing the traditional Granger causality results in this
study to the findings of the academic papers presented in table 1, we see a consistency
between our results and the outcomes found in some of the previous research.
Conclusion
In many papers the relationship between energy consumption and economic
growth has been investigated repeatedly employing different models for numerous
countries over a variety of time frames; however, despite the usage of the same
variables, we encounter various results with different coefficients and causality
relationships even in the studies for the same countries. Johansen, Engle-Granger,
and autoregressive distributed lag (ARDL) cointegration methods are used in-
tensively, but they have their shortcomings. One weakness is the avoidance of the
nonlinear structure of the time series, especially of the nonlinear GDP series, thatis evaluated as a measure of economic performance under business cycles. From
the perspective of energy economics, these models parameters were assumed to
be constant over the sample period, which suggests the relationship between GDP and
energy consumption is stable although real world experiences teach us otherwise with
numerous crises developing (1974 and 1979 oil crises, 2008 global recession).
In this paper, MS-VAR models were estimated to analyze the relationship
between energy consumption and economic growth. The MS-VAR and MS-
Granger causality approaches were utilized to evaluate causality in three different
regimes of the business cycle. In the first step in testing for causality, we determinethe integration order of LGDP and LEC using the ERS (Elliott, Rothenberg and
Stock) and Ng and Perron tests. The results indicate that the first difference of
LGDP and LEC appear to be stationary. The LGDP and LEC are integrated of
order one, I(1). Since the variables are integrated, the maximum likelihood pro-
cedure of Johansen cointegration was used to examine the possible existence of
cointegration between LGDP and LEC. According to the results, the null hy-
pothesis of no cointegration was not rejected. Although the variables are I(1), they
are not cointegrated and the first difference or innovations of the variables,
DLGDP and DLEC, will be used to test for MS-Granger causality.To analyze Granger causality between energy consumption and economic

United States, and the United Kingdomthe Markov-Switching VAR method
was used. Changes in the behavior of the variables of the MS-VAR models were
possible to detect. In this study, different MS-VAR models were estimated and the
best model was selected based on AIC and LR tests. By incorporating the business
cycles into the models, the Granger causality between energy consumption and
economic growth was investigated by MS-VAR and MS-Granger causality. The
first difference of these variables was used in the modeling process.
Causality in different regimes of business cycle and the changes in the behavior
of the variables with MS-VAR models were possible to detect. MSIA(3)-VAR(.)
models were selected for Canada, France, Italy, and the United States, while
MSIAH(3)-VAR(.) models were chosen for Germany, Japan, and the United
Kingdom. According to the first equation, the GDP appears to be the Granger
cause of energy consumption in all regimes and GDP was determined to be the
Granger cause of energy consumption in the second equation in all regimes. In
summation, we found some evidence of bi-directional Granger causality between
energy consumption and GDP. For Japan, GDP was not found to be the Granger
cause of EC in the high growth regime; however, overall, there is a bi-directional
Granger causality relationship between energy consumption and GDP. For com-
parative purposes, standard Granger causality test results were reported for the
same data sets. There is evidence that supports the growth hypothesis for Italy,
Japan, and the United States. The conservation hypothesis was best supported by
the results for Canada and France. Last, the neutrality hypothesis was supported bythe evidence from Germany and the United Kingdom.
According to the results of this paper, an increase in energy consumption di-
rectly affects economic growth and that economic growth also stimulates further
energy consumption in that country. With these findings, energy policies aimed at
improving the energy infrastructure and increasing the energy supply are the
appropriate options for these countries since energy consumption increases the
income level. Moreover, the policy of conserving energy consumption might be
implemented with little or no adverse effect on the economic growth of an
economy such as a less energy-dependent economy.
