ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 2
Introduction
29th March 2017 was a poignant year for Europe and the European Union economic
zone in Particular. On this fateful day, the United Kingdom, one of the biggest economic and
military powerhouses in the European Union, notified Brussels of its plans to exit the common
market arrangement, and in accordance with Article 50 of the treaty constituting the EU.
Consequently, the European Union’s council of heads of state and governments ratified the
ensuing negotiations and discussions between the European Union and the United Kingdom, on
29th April 2017, paving the way for the complete exit of Britain from the treaty. The Exit of the
United Kingdom from the European Union sent shockwaves among EU’s business circles and
partner member states. Ideally, the European Union formation was predicated on a political and
economic union comprised of 28 member states across continental Europe. The operating
mechanism of this giant economic zone was premised on a powerful single internal market
comprised of European economies. The common market involved the creation of a
standardized system of rules and procedures that enabled the unhindered movement of goods,
capital, and people across European country’s borders. Moreover, immigration policies and
passport controls within the Schengen as part of the European Union treaty, enabled individuals
to travel freely across the borders, without necessarily obtaining work permits or encountering
restrictions at customs or border points of respective countries. The architects of this giant
economic block appreciated the fact that the strength of an economic punch lies with the size of
its market. In this regard, hitherto Britain’s exit, the European Union was estimated to cover
more than 7 percent of the global population. Moreover, the EU was estimated to generate a
nominal Gross Domestic Product (GDP) of close to 17 Trillion USD translating to 23% of the
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 3
global wealth. More than half of total nominal GDP of the European Union was generated by
only three economies that included Germany, The United Kingdom, and France. Germany has
always been considered the leading economy in Europe contributing around 21% of the total
EU GDP, followed by Britain at 16%, with France, Italy, Spain, and the Netherlands trailing at
15%, 11%, 8% and 4% respectively. Conversely, the other eleven member states of the
European Union ranging from, Cyprus, Malta, Lithuania, Latvia, Estonia, Croatia, Slovenia,
Bulgaria, Luxembourg, Hungary, and Slovakia contributed a mere 1%of the total EU GDP.
The sheer size of the European Union’s economy exemplifies the extent of financial
ramifications that would reverberate across the world if the Union were to collapse.
Similarly, economic pundits have considered Britain, one of the biggest economic
founding member and generous donor to the European Union, as the most important driver of
the European Union economy before Brexit. Conversely, the European Union has been
considered as having given the British economy the impetus to grow by offering an enabling
mechanism. Britain joined the European Union in 1973 at its inception, and was then upbeat
about its economic future in the treaty. Indeed, Britain’s per capita income grew by a whopping
103% after joining the European Union, a major economic feat that dwarfed other formidable
economies such as the United States, Germany, and France, which grew by 97%, 99% and 74%
respectively (Sampson, 2017). The meteoric rise of the British Economy after joining the
European Union led critics in the economic block to believing that the European Union was
dragging down the British economy, and that time was ripe for the latter to exit.
The main question among the remaining European Union member countries was what
such a drastic action by one of the biggest economies portends for the rest of Europe in terms of
economic growth. Fears that the Exit of Britain from the European Union will spell doom for
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 4
the enhanced and greater integration are rife in many quarters across member countries. Pundits
posit that the exit of Britain from the Union will exacerbate the preponderance of Germany as a
major economic powerhouse, and significantly reduce the Union’s output. Populist views
across Europe contend that Brexit is the canary in the coal mine for the collapse of the
European Union as a block, precipitating major economic upheavals unprecedented in modern
history. The waning Euro-enthusiasm among the British that culminated in the Brexit vote has
been to the extent that European economies have been taking advantage of the liberal
immigration and economic laws subsisting in the European Union, to flood British cities with
immigrants and thus straining its economy by taking up British jobs. Discussions post-Brexit
has been centered on reimagining the treaty and creating a new one altogether ostensibly to
cushion member countries from the aftershocks of Brexit. In this regard, economic pundits
contend that the European Union would be on the verge of imminent collapse on the exit of
Britain from the Block. The pessimism on the performance of the EU economy post-Brexit has
been exacerbated by major disagreements between France and Germany, on how to seal the
fiscal gap occasioned by the exit of Britain from the Union. Ideally, Britain was considered the
titular head of the European Union policy formulation and a major voice in the EU parliament.
Economically, Britain was considered to pack a far much greater market and political punch
than virtually every other member of the union. The Germans, in particular, have voiced their
concerns about the future of the European Union, contending that there would be a much
slower rate of growth in the Eurozone. Moreover, Germany and her allies posit that the exit of
Britain, a major advocate for smaller budgets, leaner governments, and economic liberalism,
will significantly slacken European economy. The exit of Britain, long considered as the
European Union’s biggest single export market, will sure cause major ripples on the
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 5
Eurozone‘s market outlook. One of the major talking points regarding the effect of Britain’s
exit from the European Union is centered on motley of legal and regulatory frameworks
hitherto fronted by the UK. Evidently, stakeholders agree that post-Brexit, Britain will no
longer contribute to the European Union’s budget, a contribution estimated to be around 9
Billion Euros. In this regard, Brexit will precipitate major economic costs on the European
Union that will result in significant economic repercussions on the Union. The estimated size of
the resultant economic growth that may have a negative impact on the EU’s economy is largely
uncertain but expected to be substantial. This economic policy paper will answer the question
whether Brexit will cause or create Europe to grow faster. The hypothesis in this research and
economic policy paper is
H0- Brexit will cause the economy of Europe to grow faster
Hu-Brexit will not cause economy in Europe to Grow Faster
EU’s Economic Issues Post-Brexit
Motley of economic and political issues is poised to affect the constituent economies of
the European Union after the exit of Britain. In this regard, the divorce bill is projected to
weigh heavily on the rest of member countries’ economies by virtue of Britain’s strategic
importance in the union. Evidently, the economic and political ballgame in the European Union
will dramatically change after the exit of United Kingdom. Nonetheless, the extent of the
economic ramifications that Brexit will have on the remaining member countries’ economies
will significantly depend on the finer details of the negotiation document between Britain and
the European Union. The main variables that will help in determining the effect of Brexit on
European Union economy include Gross Value-added trade flows, foreign direct Investments
(FDI), Migration, Gross Domestic Product, and trade in goods.
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 6
Gross Value Added Trade Flows
The economic relationship between the EU and Britain can be explained the extent of
gross value added flows on either side of the economies. In this regard, the role of value-added
trade flows is indicative of the level of import-export relations between different economies.
Gross value added flows is the nominal measure of the general increases in the value of an
economy, as a result of mass production of goods and services. The basic measure of GVA is
predicated on current prices adjusted for inflationary forces, as well as the effects of the
prevailing tax regimes in a particular economy. In this regard, GVA is an important aspect of
describing the performance of the European Union member countries economy post-Brexit. In
analyzing the effects of Brexit on the European economy, it is imperative that the data be used
to show the most recent trends of the value of imports and exports between the two economies,
by eliminating any possible bias brought about by distortions in the market. The answer to the
economic health of the EU post-Brexit through the lenses of GVA lies in the critical analysis of
OECD data regarding the movement of goods and services between the two economies.
Ideally, GVA is considered a good measure of economic performance based on trade activities.
In order to fully understand the impact of GVA on EU-UK economic relations post-Brexit, the
value of imported services in the Eurozone will be subtracted from the total trade activities,
effectively leaving the value of economic activities that happened inside the European Union.
Consequently, the existing data from the OECD will be projected using a simulation of
different scenarios that depict the future of United Kingdom’s relationship with the European
Union. In this regard, the GVA data will consequently be combined resulting to an estimated
value of all the exports of goods and services to the European Union economy. The projected
reductions or increases in EU export markets because of losing market access and the resultant
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 7
economic shocks will thus be analyzed. Figures on the extent of import declines or otherwise to
the European Union will then be presented in terms of percentages to show the deviations in
absolute terms.
Similarly, the import reductions or otherwise as a result of Brexit will be compared
relative to the existing GDP baselines, ostensibly to discern economic shocks. GVA data is
particularly important in explaining economic decline or otherwise as a result of the occurrence
of a major phenomenon such as Brexit. In this regard, the European Union was formed to
promote trade and flatten immigration procedures within Europe and thus, a decline of trade or
otherwise is a key performance indicator of the effects of Brexit on constituent economies
within Europe. GVA is an important variable in determining the presence of heightened trade
activities and capturing the main impacts of productivity as a result of Brexit. In this regard,
trade in the context of European Union and Brexit aftershocks is concentrated on the activities
of financial intermediaries who often bear the shocks of major market realignment such as
Brexit. The use of GVA as a measurement variable helps in bringing to the fore economic issue
affecting both the high and low productivity sectors within the EU post-Brexit, with a view to
analyzing the economic effect of the phenomenon in question. The import and export share
value of goods and services between the remaining European Union member countries and the
United Kingdom post-Brexit, will thus be critically examined, the differences in different
shares in the various market segments will be examined, and the results tabulated for synthesis
and interpretation (Sampson, 2017). The net effects of bilateral trade data from the OECD will
help in determining the general economic direction of the European Union member countries
with respect to the exit of Britain from the Union. Any substantial decline in GVA figures
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 8
would be indicative of the fact that the view of European traders on the value of British
produced goods and services have materially diminished because of Brexit.
Similarly, the collated data from the OECD will help in explaining the reason for
relative decline or otherwise of value-added exports among the EU member country
economies, in the period to the run-up of the Brexit Vote (Sampson, 2017). The resultant
absolute value-added exports will be juxtaposed against market projections, and the various
peaks and slumps would be explained in conjunction with other variables. Any declines in
commerce volumes between the European Union and the United Kingdom will be explained
Foreign Direct Investments
Economic interdependences with reference to relations between the European Union
and the United Kingdom will be analyzed and the resultant findings juxtaposed against
previous year’s figures before the implementation of Brexit. Indeed, trade activities and foreign
direct investment are both complementary and substitute in reference to economic effects of
Brexit in the European Union (Sampson, 2017). Non-tariff barriers and single market
platforms as exemplified by European Union common market majorly influence foreign direct
investment. In this regard, FDI is the engine of economic growth for the majority of European
Union economies, and the effects variations of such variables would have a direct bearing on
the economic well-being of EU member countries. In this regard, there is a high likelihood that
the flow of FDI to the European Union will be materially diminished because of Brexit. British
firms will subsequently cut their overseas investments in Europe because of this significant
market development. Evidently, multinational firms have ingenious and complex supply chain
networks, and the effects of market uncertainties occasioned by Brexit will invariably lead to
major market disruptions in the Eurozone. Economic pundits posit that hitherto Brexit, there
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 9
were heightened trade activities in the European Union primarily because of Britain’s
membership in the block. Hitherto the activation of Brexit, the European Union economy has
seen a sustained growth in foreign direct investment a feat that is unlikely to be replicated post-
Brexit.
Migration
The presence of open borders across the European Union created a conducive
environment for the movement of goods and services that translated to heightened trade
activities for both the European Union and Britain. The sustained growth in United Kingdom
population has had a ripple effect on trade activities across the Eurozone, which would result in
a major decline post-Brexit. 2004 OECD estimates indicate that close to 2 Million Britons live
and work in the Eurozone outside the United Kingdom, exemplifying the extent to which this
variable has affected trade among European Union member countries (Sampson, 2017). The
subsequent exit of the United Kingdom from the union would, therefore, deal a major blow to
the economies of the remaining member countries. In this regard, the exit of Britain from the
European Union would herald a new chapter in the economic progress of the remaining
member countries due to the shifts in human capital because of changes in immigration laws
precipitated by Brexit.
Trade in Goods
Trade volumes between the European Union and the United Kingdom have been one of
the biggest economic pillars of the Union’s economic health. Indeed, the European Union has
over the years been enjoying massive trade surpluses in its trade activities with the United
Kingdom. OECD statistics peg the value of European Union’s exports to Britain to be more
than 300 Billion Euros, with the resultant British exports to the Union being close to about 184
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 10
Billion Euros, exemplifying the importance of the British economy to the European Union
member countries’ economies(Sampson,2017). To further cement the general feeling among
the remaining EU member countries on the effect of Brexit, Britain’s percentage share of trade
with the Union in comparison with the GDP is close to 2.5 %(Sampson,2017). The massive
trade deficit of the United Kingdom against other Eurozone countries exemplifies the extent to
which these countries would suffer once Article 50 is triggered. Similarly, OECD statistics
indicate the chronic dependency that the smaller European Union member countries have in the
United Kingdom mostly in financial aid. In fact, Germany with its thriving automobile
industry imports close to 2.8% of its GDP to Britain, while other smaller economies such as
Belgium, Ireland, and the Netherlands, and import more than 6% of their GDP to the United
Kingdom (Sampson, 2017). In terms of member States, the biggest economies In terms of trade
in volumes include Germany with value worth 34 Billion Euros, with France, Netherlands,
Ireland and Belgium following with 20, 19, 19 and 13 Billion Euros respectively. The market
size of these economies post-Brexit reveals a major fiscal hole occasioned by the exit of Britain
from the fold of the Union.
Some of the leading sectors in terms of exports from the European Union to the UK
which are projected to materially diminish as a result of Brexit include machinery and transport
sector, with an estimated value of 127 Billion Euros, road vehicles at 59 Billion Euros,
manufactured goods at 70 Billion Euros, chemicals at 51 Billion Euros, food Products at 32
Billion Euros and other minerals and mineral products at 11 Billion Euros. The resultant effects
of Brexit on the European Union’s economy are rather drastic with figures from OECD
indicating massive slumps, which have greatly affected the performance of the European Union
Economy. The comparative advantage currently being experienced by the European Union
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 11
against other formidable economies globally would be expected to decline if the UK pulls out
of the Union, and this may have far-reaching ramifications on the economic performance of the
remaining member states of the economic block.
Methodology and Hypothesis Proving
The quantitative assessment of the effects of Brexit on the general performance of the
European economy post-Brexit will involve a model-based simulation, which will take in
consideration the various economic aspects of the pullout and the expected effects on the
European economy in the end. Almost invariably, while the intended simulation model may not
capture all the macroeconomic aspects of the effects of Brexit on the European economy, it is
projected to give a general direction of the Union’s economy sans Britain. The general
hypothetical assessment of the key variables in the whole issue of Brexit and its effect on the
EU’s economy will be primarily be predicated on the position of Baseline GDP with regard to
the aforementioned variables.
Almost invariably, the envisaged model will simulate the different scenarios available
for the European Union economy post Brexit. The general hypothesis of the model will involve
simulating the future impact of the exit using a range of probable scenarios ranging from
“optimistic” ‘pessimistic” and central. The optimistic scenario assumes that both the European
Union and the United Kingdom will each enjoy the same privileges that prevailed hitherto post-
Brexit, and nothing much will change in terms of tariffs and other market restrictions because
of the exit. Nevertheless, the recent pronouncements by the British government regarding the
impending fiscal adjustments with regard to Brexit have largely hinted on some levels of
restrictions that may materially affect trade between the United Kingdom and the remaining EU
member states. The pessimistic scenario in the model, on the other hand, assumes trade
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 12
agreements than include motleys of tariffs and non-tariff market engagement between the
European Union and the United Kingdom will be reduced to the WTO baselines, and will
materially alter landscape before activation of Article 50. The pessimistic scenario is otherwise
referred to as hard Brexit in trade and diplomatic circles across Europe.
The impact of Brexit on the GDP of member countries using the aforementioned key
economic performance will be the main concern for this model. The impact of trade flows
between Britain and the European Union has been observed to diminish in various studies
across the globe. OECD estimates indicate that the value of European Union’s export to the
United Kingdom will drastically fall by close to 30% on the basis of WTO most favored nation
status (m.f.n) that the two economies are projected to enjoy after the activation of article 50.
Based on the sheer size of the two economies and the attendant volume of trade, there is a valid
projection in the value of trade between the two economies after Brexit. The ensuing market
sensitivity across the Eurozone is thus projected to occasion major shockwaves that may
greatly influence the economy of remaining European Union member countries. Specifically,
the impact of Britain’s withdrawal from the European Union on smaller and dependent
economies such as Ireland, and Belgium is expected to materially affect these countries
performances in terms of trade deficits, and consequently diminish the economy of the
European Union after reconstitution. Belgium and Ireland for instance, as other European
Union member countries are projected to face massive trade reductions in their total exports
ranging from 4% and 3%, a major development expected to greatly affect the individual
performance of these economies, and subsequently the entire European Union economy after
Brexit. The general reduction in GDP performance of the 27 member countries of the European
Union is expected to get a massive hit from the Brexit developments. On average, there are
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 13
possible loses of close to 0.11 to 0.52 percent declines in the GDP levels across the European
Union post-Brexit for both the optimistic and pessimistic scenario respectively(Gee, Graham,
Lucas & Rubin 2017). The cumulative results of the GDP concerns for both the optimistic
pessimistic scenarios are then evenly distributed across a 10-year period and the simulated
projections are juxtaposed against the probable impact of GDP slumps for the remaining
economies. In this regard, according to OECD figures, the projected declines because of the
impact of Brexit would range from 0.01% to 0.05%.
The optimistic model thus projects that the impact of Brexit based on the attendant
models, would be rather insignificant and would not materially affect the remaining 27-member
states economies post-Brexit. In this regard, the post-Brexit impact would be insignificant on
the European Union economies, and would be hardly felt or noticed at the general
macroeconomic levels. Nevertheless, individual sectors within the remaining 27 state members
may have to contend with the aftershocks of Brexit that may materially diminish the capability
of these economies in the short run after activation of Brexit clause. The projected loss for
European economies in relation to Brexit would be in the range of 1.4% to 3.5% loss relative to
their respective GDPs(Morris, Moss,Mucciarelli, & Paulus, 2018). In this regard, it is estimated
that the ratio of the United Kingdom’s economy relative to the European Union is 1:5, a factor
that is projected to accentuate the effects of Brexit on the remaining member countries’
economies. Nevertheless, a motley of economic theories posit that there will be massive losses
on both sides, but this will be more pronounced on the European economies side with
devastating consequences to future growth prospects of respective member countries, as well as
collectively. Almost invariably, it is economically believed that larger economies eventually
shed an insignificant amount of loses in case of major market realignments such as Brexit.
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 14
Ideally, both sides of the Brexit divide are projected to make significant losses after the
activation of Article 50 that ends Britain’s economic dalliance with the rest of European Union
member countries. Subsequent models by the OECD and the British national treasury indicate
significant losses on both sides of the market with European economies being the worst hit by
the Brexit aftershocks (Morris, Moss, Mucciarelli, & Paulus, 2018).
Similarly, models by the treasury department and the OECD indicate that variables such
as foreign direct investments (FDI) have a direct bearing on volumes of trade between the
European Union and the United Kingdom. Foreign direct investment has a direct bearing on
economic factors such as research and development that eventually lead to innovation and
subsequent economic competitiveness in any economy globally.
The general operation of the proposed model to gauge the impact of Brexit European
economy will be based on empirical estimates from the OECD and the national treasury in the
United Kingdom. The measurable variables with respect to key economic performance
indicators will be assessed based on their cost-reducing effects on the UK and the EU economy
or otherwise (Armstrong & Portes, 2017). In this regard, the model to be used will evaluate
post-Brexit effects, which will range from the Schengen agreement that has a direct bearing on
immigration as a variable, the tariffs and non-tariff barriers expected to be introduced post-
Brexit, as well as the various market realignments. In this regard, the gravity model will be
used to distinguish between goods and services, and assign economic values to the various
economic indicators. On the basis of trade elasticity, the extent to which Brexit is expected to
create new trade barriers or otherwise that would invariably lead to sluggish European
economic growth. The application of trade barriers simulation on the effects of Brexit is
particularly important since the Union was predicated on a common market. In this regard, the
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 15
presence of trade restrictions presupposes a sluggish economy on either part of the two divides.
The Gravity model is then used to perform an aggregated regression for goods and services in
the current composition of the European Union.
Existing Literature on Effects of Brexit on European Economy.
The effect of Brexit on the economic performance of the European Union has been a
controversial topic among policy experts and pundits. Various studies have been conducted
regarding the contribution of the United Kingdom to the European Economy, and how Brexit
has changed the balance of economic power. Sampson posits that the biggest losers in the
Brexit deal will not entirely be the European Union member countries, rather, the British
economy will be hit due to the lost markets. The imposition of trade barriers to the UK because
of Brexit will herald a new chapter in increased cost of production and trade for both
economies leading to sluggish growth (Sampson, 2017). Studies by Mihela and Simonescu
delve into the effects of trade barriers, immigration policies, and their bearing on the European
Union’s economic outlook. Brexit is projected to occasion massive layoffs, austerity measures
and mass closure of companies in the Eurozone due to the drastic changes in rules of operations
and budget constraints because of Brexit (Mihela & Simonescu 2016)
Data Sources
The policy paper will rely on OECD data and the relevant information from statistics
bureau and Bretton woods institutions market outlook policy papers. Moreover, accommodate
research articles by various economic researchers on the effects of Brexit have been
accommodated in arriving at a conclusion of the study in the paper.
Conclusion
ECONOMIC ANALYSIS AND POLICY RECOMMEDATIONS 16
Based on the data from the different think tanks and Brexit watchers, as well as the
results of the economic model therein, it is apparent that there will be a significant disruption of
trade links between the United Kingdom and the European Union, with far-reaching
ramifications to both economies. Nevertheless, the extent of such an economic hit on the EU
economy will be disproportionately measly due to the presence of bigger economies such as
Germany and France, who are expected to fill the trade vacuum left by the United Kingdom

Policy Recommendations
Based on the regression model, it is apparent that the levels of disruptions as a result of
Brexit on the European Union Member countries’ economies will not be significant enough to
warrant a reimagining of the treaty. In fact, most of the economic shocks will be felt by the
United Kingdom itself due to the lost volumes of trade as well as immigration benefits to
citizens. The European Union Economy is projected to experience heightened trade activities
from Germany and France, scrambling to fill the void left by the exit of Britain leading to new
bursts of energy on the economic prospects of the Union.
