Abstract
This article presents a comparative statics analysis of the potential impact of oil price
rises on the EU economy. The macroeconomic and sectoral effects of such oil shocks
are quantitatively assessed for two basic scenarios with the GEM-E3 world model.The first scenario assumes a crisis leading to an increase of 10$ per barrel of oil. The
second one consists of a much deeper energy crisis, and translates into a rise of 30$
per barrel of oil. The crude petroleum, petroleum refineries and energy-intensive
sectors undergo a significant fall in their value-added. Almost 40% of the overall
GDP fall comes from the Other market service sector, while the Trade and Transport
sector and the Other equipment goods sector represent each approximately 10% of the
overall GDP fall.
The GDP losses for the EU as a whole are 0.94% in the first scenario and 2.56% in
the second. The macroeconomic impact is slightly lower in the USA (0.81% and
2.21%, respectively). Australia, the FSU, India and Japan have very similar losses to
that of the whole EU, while China and Africa experience a bigger GDP drop. The
world GDP loss figures are very similar to those of the EU.

1 Introduction
Nowadays approximately half of the EU energy needs are imported. The dependence
on external sources of energy supply is expected to rise considerably in the coming
decades, to around 70% in 2030 (European Commission, 2001). This entails a
significant potential vulnerability of the EU economy to eventual oil price rises. For
instance, geopolitical instability in the Middle East can alter the world oil market,
which in turn would significantly affect the EU, as already occurred in the 1970s oil
shocks2.
This article addresses the economic consequences on the EU associated to an oil price
crisis and, in particular, quantitatively assesses the potential macroeconomic and
sectoral effects of two oil shock scenarios on the EU economy3. An increase in oil
prices leads both to a real loss of income in the EU and, through changes in relative
prices, to a significant reallocation of resources within the goods, services, capital and
labour markets. In order to analyse such macroeconomic impacts the world General
Equilibrium Model for Energy-Economy-Environment interactions (GEM-E34) has
been applied.
GEM-E3 is a computable general equilibrium model of the world economy able to
quantify those impacts by using the relevant contributions from economic theory and
adequate statistical data bases (based mainly on social account matrixes). The model
computes the equilibrium prices of goods, services, labour and capital that
simultaneously clear all markets in the world regions.
2 The Focus section of the Quarterly Report on the Euro Area (European Commission, 2003a) studiedthe economic consequences of the Iraqi conflict on the economy of the euro area. Similar studies havestudied the consequences on the US economy (see Nordhaus (2003) and Perry (2001)). For the analysisof the macroeconomic effects of higher oil prices see for instance Hudson and Jorgenson (1978) andHunt et al. (2001).
3 The design of the scenarios of this exercise has been made jointly by DG TREN C1 and IPTS/JRC.The model scenarios have been implemented and run by NTUA.
4 The GEM-E3 model was constructed by a collaborative project team, partially financed by theJOULE Programme of the European Commission (DG RTD), and involved NTUA as a co-ordinator,KUL/CES, University of Toulouse, University of Mannheim, University of Strathclyde and CORE.The model has been widely used in studies for the European Commission, including The Review of theSingle Market, The Double-Dividend Analysis, The Evaluation of Energy Taxation, The Macro-Economic Costs for the EU of reaching the Kyoto targets, and others. The model has been successfully
peer reviewed by the European Commission in 1998.

This article has four sections, in addition to this introduction. In the first section the
past oil shock experiences are reviewed. Section two presents the methodology
followed in this article. Section three analyses the main results. Section four
concludes.
2 Review of past oil-shock experiences
The evolution of oil prices for the period 1970-2001 is shown in Figure 1 both in
current and constant (1999 $) terms. The two oil shocks of the 1970s, 1973-1974 and
1979-1980, can be clearly identified. Real oil prices quadrupled during the first shock
and tripled during the second shock.

2.1 Oil production disruptions and oil prices
The major cause explaining the 1970s oil crises are exogenous disruptions in world
petroleum supply. According to the computations of Hamilton (2003) the drop in
world production in the 1973 Arab-Israel war could be estimated to be 7.8%, and
8.9% in the 1978 Iranian revolution.

The OPEC cartel controls a large part of the world oil production and most of the
proven reserves5. The behaviour of the OPEC countries, and in particular its degree of
coordination in supplying the world oil market, plays a significant role in the
determination of the world oil prices. The oil market is difficult to model due to its
non-competitive nature. When OPEC countries have succeeded in controlling their
supply provided to the world oil market, the cartel has been able to significantly
influence prices.
2.2 Macroeconomic effects of past shocks on the EU economy
The effects of 1970s oil price shocks on economic growth have been substantial. In
general terms, they provoked slower economic growth, higher unemployment, a
process of employment destruction and higher inflation rates. Table 1 and Figure 2
present the case of the 1979 shock. As it can be seen, the rise in oil prices that took
place during 1979 was followed by very low economic growth rates in the 1980-1982
period.

However, before reviewing the empirical evidence on the effects of oil price shocks
on the economy, it is interesting to recall the actual dependence of the EU on oil
imports. Table 2 gives the gross inland consumption of oil in the EU and compares itwith the net oil imports for the period from 1985 to 1999. The rate of oil dependence

has remained relatively high (above 75%) for the whole period, pointing out the
vulnerability of the EU economy to hypothetical future oil shocks in the future6.

2.3 GDP loss due to more expensive oil imports
One immediate effect of higher oil prices is more expensive oil imports, which given
the share of oil net imports in the EU economy, leads to a fall in GDP. According to
Eurostat in 2001 EU net imports of petroleum and petroleum products amounted to
87.7 billion Euro, 0.99% of GDP. The average price of the Brent oil was 24.77
dollars. An increase of 10 dollars in the price of oil would lead, keeping constant the
volume of oil imports, to a fall of 0.40% of GDP, and a 30 dollars increase would
reduce GDP by 1.20%. These estimates do not take into account other fundamental
effects of oil price shocks that further affect GDP (e.g. the fall in GDP due to more
expensive imports depress consumer spending, triggering chain effects on the overall
economy, in addition to the effects on demand because of uncertainty) and, therefore,
are to be interpreted as underestimates of the actual impact of an oil price shock on
GDP.
2.4 Statistical and econometric estimates of the oil price-GDP relationship
The relationship between oil price and GDP appears to have been relatively linear
after World War II to the late 1970s7. This would imply that either a positive or a
negative oil shock would affect economic activity by the same magnitude.
However, with the drop in oil prices in the 1980s GDP did not rise as the noted linear
relationship would imply. Therefore, a series of econometric studies has intended to
restore the stability of the relationship between oil prices and GDP through non-linear
6 See the EU green paper on security of energy supply (European Commission, 2001).
7 In mathematical terms the log of real GDP is linearly related to the log of the real price of oil

specifications, leading notably to asymmetric responses of GDP to oil price changes8.
These studies conclude that increases in oil price affect GDP more than drops in oil
prices9.
Concerning the magnitude of the oil price-GDP relationship Jones et al. (2002)
conclude that the oil price-GDP elasticity for the US economy is around -0.055, this
being this the cumulative effect on GDP over a 2-year period of a shock in one period
only, regardless whether the price increase is sustained10.
2.5 Model-based estimates of the macro effects of oil crises
The transmission mechanisms through which an oil shock affects GDP are made
explicit in economic models. There are two major channels. First, an increase in the
oil price alters the supply of the economy because of the raise in energy costs, which
provokes a supply-driven recession. Second, an oil shock also affects the demand-side
of the economy due to the effect of lower income on consumer and business
behaviour. Furthermore, there is an additional demand-side effect because consumer
spending and investment decisions are postponed due to the uncertainty about the
future oil prices11. The fall in the consumption and investment components of
aggregate demand therefore provokes a recession in the economy.
The accuracy of the estimated impacts depends of course on the model
characteristics12. The better the transmission channels of the oil shock are modelled,
the more reliable are at first the quantitative estimates.
8 See e.g. Hooker (1997) and Hamilton (2003).
9 Hamilton (2003) notes that there is evidence suggesting that oil shocks are important because theydisrupt spending by consumers and firms on certain key sectors of the economy.
10 It could be argued, applying the arc elasticity concept, that this value of the elasticity implies that a50% increase in the price of oil would lead to a fall in GDP of 2.75%. Doubling the oil price wouldlead to a 5.5% loss of GDP.
11 The irreversible investment model, stating that uncertainty situations lead to postponement ofinvestment decisions because of the intrinsic irreversibility nature of the investment decisions, is of
particular significance in this respect.
12 See the interesting discussion on this issue in section 5 of Jones et al. (2002), which deals with theIMFs MULTIMOD and the OECDs INTERLINK models.

3 Methodology3.1 The GEM-E3 Model
GEM-E3 World model is a multi-region applied general equilibrium model of the
world economy providing detailed results on macroeconomic variables, sectoral
activity, trade and their interaction with the environment13. It is an empirical, large-
scale model, calibrated to a base year14 using the Global Trade Analysis Project
(GTAP) v.4 database. The model is not stochastic15.
The model aggregates the national economies of the world into twenty-one regions,
among which four EU regions, and links them through endogenous trade of goods and
services. GEM-E3 includes twenty sectors and various economic agents, for which it
formulates their individual economic behaviour and their interactions as demanders
and suppliers of goods and services. The model covers the major aspects of public
finance, including all substantial taxes, social policy subsidies, public expenditures
and deficit financing. One feature of the modelling approach consists of the absence
of involuntary unemployment by definition. At the market real wage labour supply
equals labour demand.
The model determines the equilibrium prices and quantities that simultaneously clear
all markets, taking into account the optimising behaviour of economic agents. The
results of GEM-E3 include detailed input-output tables by region, national accounts,
employment, balance of payments, public finance, household consumption, and
energy use and supply, among other endogenous variables. The computation of the
equilibrium is simultaneous for all domestic markets and their interaction through
flexible bilateral trade flows.
3.2 Definition of Scenarios
The model application implemented compares two cases:
- Baseline case: basically capturing the current state of the economy.
13 See Capros et al. (1997).
14 The base year of the current version of the model is 1995.
15 Sensitivity analyses in order to assess the robustness of some outputs are of course possible.Applying Monte-Carlo techniques for this purpose, however, is almost impossible due to the modelsize.
7/30/2019 Vulnerability of the EU Economy to Oil Shocks

- An alternative case with an increase in the oil price due to geopolitical instability
in the Middle East region. Two scenarios of interest have been studied16.
- Scenario 1. The crisis leads to a rise of 10$ per barrel in the world oil price.
- Scenario 2. Under this scenario there is a sharp rise of oil price. This increaseis assumed to be 30$ per barrel.
This is a typical exercise of comparative statics. The differences between the baseline
and the alternative case are the consequences of the oil price change. In particular, the
higher oil prices implied by the alternative scenarios impose an additional cost to the
economy, therefore modifying the optimal choices of the economic agents. The
resulting prices and quantities characterise the new equilibrium, in which supply
equals demand in all markets, once all adjustments have occurred17. This equilibrium
approach allows taking into consideration not only the direct effect of an oil shock,
but also the indirect and feedback effects between markets (multi-sectoral approach).
The model is explicitly considering the substitution possibilities of the economy as a
whole, e.g., the substitution of oil (an input relatively more expensive after the oil
shock) for gas and coal and, on a more aggregate level, the substitution of energy (a
comparatively more expensive production factor) by other factors, i.e. labour and
capital.
The causes behind the oil price increases are not addressed in this paper. An oil price
rise could be motivated by a real oil supply shortage (induced, for instance, by a
geopolitical crisis) or by an expected oil supply shortage, when agents discount or
anticipate a possible but not yet accomplished oil shock18.
3.3 Interpretation, Caveats and Limitations of the Methodology
Before discussing the output of the model runs, it is important to remark the following
points:
16 Annex 3details the implementation of the oil shocks in the model.
17The time path of the adjustment to the oil price shock is not modelled explicitly. Information fromdynamic models would be needed to give an indication of that adjustment path over time. Assumptionscould be made concerning the responses of economic agents (including the government, for instance oncompensation for the rise in oil prices) that would indeed affect the impact of the shock on the differentmacroeconomic variables.
18 The oil price outburst of January-March 2003 would follow this pattern. International oil marketsanticipated for a relatively long period the possibility of an oil shortage due to the crisis in the Gulf.
7/30/2019 Vulnerability of the EU Economy to Oil Shocks
11/29
11
It is important to take into account the essence of the general equilibrium
approach in what concerns the interpretation of the results. The results in the
alternative scenarios are always interpreted in relative terms, as changes or
differences with regard to the baseline scenario.
The model is formulated and solved in real terms. Monetary and financial issues
are not considered.
The results of the model runs are notpredictions or forecasts. The model gives
insights on the order of magnitude and sign of the evolution of economic variables
if there were an oil shock and if the economy adjusted completely to the new oil
prices. The equilibrium paradigma in economic theory is being assumed.
In the model runs the oil shock affects the economy through its effect on the oil
price (substitution and income effects), but in addition there are other transmission
mechanisms, such as the effects due to the increased uncertainty faced by
economic agents (decision to postpone investment and consumption decisions,
rise in risk premium in financial assets, etc), not considered explicitly in the
model19.
It should be noted that the applied model assumes full market flexibility and
optimal behaviour of economic agents. Yet the experience of the previous oil
shocks indicates that because of market imperfections and rigidities (particularly
in labour markets) the actual macroeconomic impacts may be higher than those
given here, due to this non-addressed inefficiency costs.
The results to can be interpreted in time-proportional terms in the following sense.
The shock takes place in a certain year and the measured results all are defined in
annual terms. Therefore it could be interpreted that if the actual price increase in
oil prices is for instance half the size of the assumed in scenario 1, the effect on
GDP would be half the estimated one20.
No changes of economic policy in response to the oil shock have been assumed.
19 The worse case scenario of the 2003 Spring Economic Forecast (European Commission, 2003b)would lead to a fall of GDP of almost 1% in the euro area according to the QUEST model, of whichapproximately 30% could be attributed to the rise in oil prices and the rest to the fall in confidence, therise in the risk premium and financial stress.
20 This proportionality principle can be applied because the production functions are constant-elasticityof substitution (CES ) type and log-linear.

4 Results
4.1 Macroeconomic effects in the EU as a whole
The macroeconomic effects of the two scenarios, as compared to the baseline or
reference case are shown in Table 3. In scenario 1 GDP in the EU falls by 0.94%21.
This reflects the impoverishment effect caused by the energy shock. A basic
production factor, oil, has become more expensive and this provokes a GDP loss
because the level of production of the baseline case cannot be attained. Indeed, the fall
in GDP has its main origin in the diminution of the productivity of the production
factors in the economy. From the aggregate demand perspective, the GDP loss is
mainly caused by a fall in private consumption (which diminishes by 1.39%), the
main component of GDP. The consumption possibilities of households decrease, due
to the fall in real wages. Regarding the trade flows, exports diminish mainly because
of the global economic slowdown (world GDP falls by 0.93% and by 2.54% in
scenarios 1 and 2, respectively). Imports also diminish due to the lower GDP level.
Since labour becomes relatively cheaper than oil as a production factor, under the new
equilibrium the employment level is slightly higher than in the baseline case.
Table 3. Macroeconomic Effects on the EU
Scenario 1 Scenario 2
GDP -0.94% -2.56%
Private Investment -0.16% -0.45%
Private Consumption -1.39% -3.83%
Exports in volume -0.83% -2.14%
Imports in volume -0.59% -1.63%
Employment 0.03% 0.08%
With respect to scenario 2, the sign of the effects is the same but the intensity much
higher. In this case, GDP falls in the EU by 2.56%, and private consumption by
3.83%. This GDP loss is close to the long-term annual economic growth (in the range
of 2 to 3%)22.
21 This represents approximately 84.6 billion Euro, in current terms.
22 EU real average economic growth in the 1961-2002 period has been 2.98%, and during the 1990-2002 period 2.03%.

4.2 Macroeconomic effects in the EU regions
Table 4 presents the macroeconomic effects for the four EU regions of the model:
Germany (D), UK,NEUregion (composed of Denmark, Sweden and Finland) and the
rest of EU countries (OEUregion). The UK region seems to be the one relatively least
affected by the energy shock, which could be explained by its oil resources, while
Germany (D) and the other EU countries (OEU) region are the most affected.

The impact of the oil shock on GDP can be decomposed into the various aggregate
demand components of GDP, by using the following standard national accounts
identity:
GDP= Consumption + Investment+ Public expenditure + Exports Imports
Table 5 presents the results of such decomposition.

Note: NEU= DK, S, FIN; OEU= other EU countries
In the OEU and UK regions most of the GDP fall is explained by the behaviour
private consumption23. Moreover, the fall in imports approximately mitigate a quarter
of the overall GDP contraction. With regard to the D and NEU regions, the
contribution of private consumption is lower than in the OEU and UK regions.
For the EU as a whole the contribution of the fall in exports to the overall GDP fall is
around 25%. When the fall in imports is taken into account, the contribution of
external trade is negative in both scenarios, explaining around 5% of the GDP fall.
This is indeed reflecting the competitiveness loss of the EU due to the oil price rise.
With regard to the contribution of public expenditure it is zero, by definition since it
is assumed that public expenditure policy does not change after the shock, and
remains the same across all cases and scenarios.
23 The role played by the model disaggregation of the EU into four regions should be taken intoaccount. In particular, the intra-EU trade is visible in the form of export and import flows for thesingle-country regions of the model (Germany and UK) and to a lesser extend in the NEU and REUregions (composed of three and ten countries respectively)"

4.3 Sectoral effects in the EU and EU regions
The sectoral24 effects of the oil shock are given in Table 6. The oil price shock is at a
first stage affecting mainly the oil-related sectors, but due to the interlinkages
between the economic sectors, the shock in transmitted to the rest of the economy
through a series of market adjustments. The results presented below give the situation
once those adjustments have taken place in the new equilibrium. The change in value-
added of each sector, compared to the baseline, is in fact offering an interesting
perspective of the major sectoral adjustment processes taking place in the economy.
In general terms, both supply (firm decisions) and demand (household decisions)
factors lead to a relative shift in the sectoral value-added of the economy towards less
oil-intensive sectors.

two scenarios, relative to the baseline. Unit costs increase in all sectors, showing the
productivity fall in the production factors of the economy, induced by the oil price
shock. In both scenarios the highest increases in unit costs are located in the oil-
related sectors. In scenario 1 Crude petroleum unit costs rise by 30%, andPetroleum
refineries costs rise by 13%. Those higher unit costs, as well as the relative change in
costs vis--vis other primary fuels, lead to a significant drop in the economic activity
of the two oil-related sectors, as can be seen in Table 6.
The coal and gas sectors (number 2, 4 and 20) on the contrary see an improvement in
their value-added in both scenarios, due mainly to the substitution effect among the
primary fuels. As can be seen in Table 7 their unit costs rise quite less than those of
oil products. With regard to the industrial sectors, those with higher oil-intensityexperience a higher relative drop in value-added. TheFerrous and non ferrous metals
sector, Other manufacturing products and theFood industry are those most relatively
affected by the oil shock. The Construction sector (with low exposition to external
competition) experiences a relative contraction slightly below that of GDP. TheNon-
market services sector (composed mainly by the public sector services e.g. health and
education) is relatively little affected by the shock and, indeed, its unit costs rise by
the lowest rate. The Other market services sector value-added drops more than total
GDP. Indeed, almost 40% of the overall GDP fall comes from this sector, while the
Trade and Transport sector and the Other equipment goods sector represent each
approximately 10% of the overall GDP fall. In this respect, it might be of interest to
give a closer look at the shares of each sector in the GDP loss provoked by the oil
shock. Table 825 represents the sectoral shares of GDP in the base year (baseline) and
the shares of GDP losses in the two scenarios for the four EU regions of the model, as
well as for the EU as a whole. The following results for the whole EU can be
remarked:

The oil shock seems to affect significantly the demand for private services, and
proportionally to their share in GDP. Indeed, almost half (47% to 48%) of the overall
fall in GDP in both scenarios is located in the Other market services and Trade and
transport sectors, a very similar figure to their joint participation in GDP (48.7%).
With regard to the Other market services sector, while it represents 30.2% of GDP in
the base year, it is the sector absorbing the highest share of the GDP loss,
approximately 37.5% in both scenarios. On the contrary, the Trade and transport
sector is relatively less affected by the oil shock: representing 18.5% of GDP in the
baseline, it absorbs 10.2% of the GDP fall. This might be due to the composition of this
sector. While the demand for transport services component is much affected by the oil
price shock, the trade component is relatively less sensitive to such shock.
The third sector in importance according to the share in the overall GDP fall is the
Other equipment goods sector. While it accounts for 6% of GDP in the baseline, it
represents around 10% of the GDP loss in both scenarios. The equipment goods might
be longer used, and therefore later replaced, in a context with higher energy prices.
Energy-intensive sectors (theFerrous and non ferrous metals, Chemical products and
Other energy intensive sectors), which account all together for 7.7% of GDP in the
baseline, absorb 8.2% of overall impact in GDP. TheFerrous and non ferrous metals
sector is the one that undergoes the highest relative impact. While it represents 1% of
GDP, it absorbs 2% of the GDP fall. This is explained by the evolution of its unit costs
of production, which rise at the highest rate among the industrial and service sectors.
The primary energy and transformation sectors (Coal, Petroleum refineries,
Distribution of gaseous fuels and manufacture of gas, Crude petroleum and Natural
gas production) account for very little of the overall GDP fall (in the range of 1.2 to
1.4%), and have a very similar share in GDP (1.3%). TheDistribution of gaseous fuels
and manufacture of gas sector is the only sector in the economy enjoying an
improvement. Its production increases, contributing positively to the GDP of the
economy by 0.2% and 0.1 % of the overall GDP fall in scenarios 1 and 2, respectively.
4.4 World region results
The GEM-E3 world model provides with macro and sectoral results, of the same kind as
those seen in the previous subsections, for the seventeen non-EU regions. For brevity,

economy26. Compared to the impact on the EU as a whole, for scenario 1 the USA (with a
significant domestic oil production) has a lower GDP loss (of 0.81%, compared to a 0.94%
in the EU). The same happens for scenario 2. Australia, India and Japan have very similar
losses to that of the whole EU, while China and Africa (very vulnerable because of their
lack of domestic oil resources and, for the case of China its fast economic growth)
experience a much bigger GDP drop. The world GDP loss figures are very similar to those
of the EU.

5 Conclusions
Oil imports in the EU account for approximately 1% of GDP. However, in spite of such
low figure, oil price increases produce a major effect on economic growth, due to the
essential role played by oil in the economy. Indeed, around 75% of oil consumption is
imported from abroad, which makes the EU particularly vulnerable to possible energy
crises.

An analysis of the potential impact of oil price rises on the EU economy has been
conducted applying the GEM-E3 world model. Two scenarios have been considered. The
first scenario assumes an increase of 10$ per barrel of oil. The second one consists of a
much deeper energy crisis, and translates into a rise of 30$ per barrel of oil. The GDP
losses for the EU as a whole are 0.94% in the first scenario and 2.56% in the second.
The macroeconomic impact of the oil shocks is slightly lower in the USA (0.81% and
2.21% for the two scenarios, respectively). Emerging economies, such as China, seem to
be relatively more vulnerable to the shock than advanced OECD economies.

Annex 3. Implementation of the Oil Price Shocks in the Model
The alternative scenarios have been implemented in the GEM-E3 model in the following
way:
(1) The lower accessibility of the oil reserves in the Middle East region provokes a shortage
of supply. Such a fall in oil production translates into an increase, relative to the baseline,
of 30% and 90% in Scenarios 1 and 2, respectively.
(2) In order to have the same oil price across all regions of the model, a dummy levy on oil
production was imposed.
(3) The revenues from that production levy are recycled to firms.
