BCO221 GLOBAL ECONOMICS – Task brief & rubrics
Task brief
Description:
· Individual task.
· First, answer the following two questions (60%) Then, write a
report (40%).
Questions (60%)
Question 1 (30%). Explain the Bretton Woods system. You
should refer to:
· As a result of the Bretton Woods system, what happened with
the exchange rates? Was it fixed? Was it floating? (10p)
· Why did the Bretton Woods system collapse? (10p)
· Would be such a system feasible nowadays?
Question 2 (30%). With reference to real world examples assess
the pros and cons of different exchange rate systems. In your

13. answer you should refer to:
· Floating exchange rate regimes – you should in particular
consider whether floating currencies are condusive to promoting
international trade.
· Pegged exchange rate regimes and pegged with bands
exchange rate regimes – you should consider the possibility of
currency crises in relation to the pegged with bands currency
regimes and should consider an actual currency crisis such as
the 1992 Black Wednesday Crisis for the pound and its
membership of the ERM.
· Single currencies – in relation to single currencies you should
consider the pros and cons of the Euro, you should bring in the
Optimal Currency Area argument, and you should in particular
consider whether a nation like Greece in the aftermath of the
2008 Financial Crisis suffered more than it would have if it had
not been a part of the Eurozone (due to its inability to devalue
its currency or implement a looser monetary policy) and you
should also consider whether the ECB has reponsed adequately
to the economic challenges of the current coronavirus crisis (i.e.
should the ECB be implementing a looser monetary policy in
particular right now). You should consider whether a one size
monetary policy does fit all.
Report (40%)
You are asked to develop and write a final report to assess the
case study of the transition to electric mobility and its effects in
global economics.Your work should come with in-depth
reasoning and justification with well founded facts, events,
figures and academic arguments. Please also refer to authors,
models, themes and concepts learned in the course. You may
define, evaluate and apply these when needed. Critical thinking
is welcomed when justyfiying your alternatives and answers.
Please read the following case study summary about the 2019
edition of the Global EV Outlook, which is the flagship
publication of the Electric Vehicles Initiative (EVI) within the
IEA (International energy agency), at the 10th Clean Energy

14. Ministerial (CEM) meeting that was held in Vancouver on 27
May 2019.
Electric car deployment has been growing rapidly over the past
ten years, with the global stock of electric passenger
cars passing 5 million in 2018, an increase of 63% from the
previous year. Around 45% of electric cars on the road in 2018
were in China – a total of 2.3 million – compared to 39% in
2017. In comparison, Europe accounted for 24% of the global
fleet, and the United States 22%.
Table 1. Global electric car sales and market share, 2013-18
The number of charging points worldwide was estimated to be
approximately 5.2 million at the end of 2018, up 44% from the
year before. Most of this increase was in private charging
points, accounting for more than 90% of the 1.6 million
installations last year.
Electric mobility is expanding at a rapid pace. In 2018, the
global electric car fleet exceeded 5.1 million, up 2 million from
the previous year and almost doubling the number of new
electric car sales. The People’s Republic of China remains the
world’s largest electric car market, followed by Europe and the
United States. Norway is the global leader in terms of electric
car market share.
Policies play a critical role. Leading countries in electric
mobility use a variety of measures such as fuel economy
standards coupled with incentives for zero- and low-emissions
vehicles, economic instruments that help bridge the cost gap
between electric and conventional vehicles and support for the
deployment of charging infrastructure. Increasingly, policy
support is being extended to address the strategic importance of
the battery technology value chain. Policies continue to have a
major influence on the development of electric mobility. EV
uptake typically starts with the establishment of a set of targets,
followed by the adoption of vehicle and charging standards. An

15. EV deployment plan often includes procurement programmes to
stimulate demand for electric vehicles and to enable an initial
roll-out of publicly accessible charging infrastructure. Fiscal
incentives, especially important as long as EVs purchase prices
are higher than for ICE vehicles, are often coupled with
regulatory measures that boost the value proposition of EVs
(e.g. waivers to access restrictions, lower toll or parking fees)
or embedding incentives for vehicles with low tailpipe
emissions (e.g. fuel economy standards) or setting zero-
emissions mandates. Policies to support deployment of charging
infrastructure include minimum requirements to ensure EV
readiness in new or refurbished buildings and parking lots, and
the roll-out of publicly accessible chargers in cities and on
highway networks. Adoption of standards facilitates inter-
operability of various types of charging infrastructure.
Table 2. EV-related policies in selected regions
Technology advances are delivering substantial cost cuts. Key
enablers are developments in battery chemistry and expansion
of production capacity in manufacturing plants. Other solutions
include the redesign of vehicle manufacturing platforms using
simpler and innovative design architecture, and the application
of big data to right size batteries. Technology developments are
delivering substantial cost reductions. Advances in technology
and cost cutting are expected to continue. Key enablers are
developments in battery chemistry and expansion of production
capacity in manufacturing plants. The dynamic development of
battery technologies as well as recognition of the importance of
EVs to achieve further cost reductions in the broad realm of
battery storage has put the strategic relevance of large-scale
battery manufacturing in the limelight of policy attention.
Other technology developments are also expected to contribute
to cost reductions. These include the possibility to redesign
vehicle manufacturing platforms using simpler and innovative
design architecture that capitalise on the compact dimensions of

16. electric motors, and that EVs have much fewer moving parts
than ICE vehicles. As well as the use of big data to customise
battery size to travel needs and avoid over sizing the batteries,
which is especially relevant for heavy-duty vehicles.
The private sector is responding proactively to the policy
signals and technology developments. An increasing number of
original equipment manufacturers (OEMs) have declared
intentions to electrify the models they offer, not only for cars,
but also for other modes of road transport. Investment in battery
manufacturing is growing, notably in China and Europe.
Utilities, charging point operators, charging hardware
manufacturers and other stakeholders in the power sector are
also increasing investment in the roll-out of charging
infrastructure. This takes place in an environment that is
increasingly showing signs of consolidation, with several
acquisitions by utilities and major energy companies.
Other developments to induce continued cost cuts include
options to redesign vehicle manufacturing platforms to use
simpler and innovative design architecture, taking advantage of
the compact dimensions of electric motors and capitalising on
the presence of much fewer moving parts in EVs than in ICE
vehicles. This is in line with a recent statement from
Volkswagen concerning the development of a new vehicle
manufacturing platform to achieve cost parity between EV and
ICE vehicles. Adapting battery sizes to travel needs (matching
the range of vehicles to consumer travel habits) is also critical
to reduce cost by avoiding “oversizing” of batteries in vehicles.
For example, instruments allowing real-time tracking of truck
positioning to facilitate rightsizing of batteries. Close co-
operation between manufacturers to design purpose-built EVs
are not only relevant for freight transport, but also in order to
meet range, passenger capacity and cargo space requirements
for vehicles used in shared passenger fleets (e.g. taxis and ride-
sharing).
Technology is progressing for chargers, partly because of
increasing interest in EVs for heavy-duty applications

17. (primarily buses, but also trucks). Standards have been
developed for high-power chargers (up to 600 kilowatts [kW]).
There is growing interest in mega-chargers that could charge at
1 megawatt (MW) or more (e.g. for use in heavy trucks,
shipping and aviation).
Private sector response to public policy signals confirms the
escalating momentum for electrification of transport. In
particular, recent announcements by vehicle manufacturers are
ambitious regarding intentions to electrify the car and bus
markets. Battery manufacturing is also undergoing important
transitions, including major investments to expand production.
Utilities, charging point operators, charging hardware
manufacturers and other power sector stakeholders are also
boosting investment in charging infrastructure. The private
sector is responding proactively to the EV-related policy signals
and technology developments. Recently, German auto
manufacturers such as Volkswagen announced ambitious plans
to electrify the car market. Chinese manufacturers such as BYD
and Yutong have been active in Europe and Latin America to
deploy electric buses. European manufacturers such as Scania,
Solaris, VDL, Volvo and others, and North American companies
(Proterra, New Flyer) have been following suit. In 2018, several
truck manufacturers announced plans to increase electrification
of their product lines.
Battery manufacturing is undergoing important transitions,
notably with increasing investment in China and Europe from a
variety of companies, such as BYD and CATL (Chinese); LG
Chem, Samsung SDI, SK Innovation (Korean) and Panasonic
(Japanese). This adds to the already vast array of battery
producers, which led to overcapacity in recent years, and
confirms that major manufacturers have increased confidence in
rising demand for battery cells, not least because major
automakers such as BMW, Daimler and Volkswagen are looking
to secure supply of automotive batteries.
Utilities, charging point operators, charging hardware

18. manufacturers and other stakeholders in the power sector are
increasing investment in charging infrastructure. This is taking
place in a business climate that is increasingly showing signs of
consolidation, with several acquisitions from utilities as well as
major energy companies that traditionally focus on oil. This
covers private charging at home, publicly accessible chargers at
key destinations and workplaces, as well as fast chargers,
especially on highways. Examples of investments covering
various types of chargers come from ChargePoint, EDF, Enel
(via Enel X), Engie (via EV-Box). Some utilities (e.g.
Iberdrola), automakers and consortia including auto industry
stakeholders (e.g. Ionity) focus mostly on highway fast
charging.
The projected EV stock in the New Policies Scenario would cut
demand for oil products by 127 million tonnes of oil equivalent
(Mtoe) (about 2.5 million barrels per day [mb/d]) in 2030, while
with more EVs the in the [email protected] Scenario the reduced
oil demand is estimated at 4.3 mb/d. Absent adjustments to
current taxation schemes, this could affect governments’ tax
revenue base derived from vehicle and fuel taxes, which is an
important source of revenue for the development and
maintenance of transport infrastructure, among other goals.
Opportunities exist to balance potential reductions in revenue,
but their implementation will require careful attention to social
acceptability of the measures. In the near term, possible
solutions include adjusting the emissions thresholds (or the
emissions profile) that define the extent to which vehicle
registration taxes are subject to differentiated fees (or rebates),
adjustments of the taxes applied to oil-based fuels and revisions
of the road-use charges (e.g. tolls) applied to vehicles with
different environmental performances. In the longer term,
gradually increasing taxes on carbon-intensive fuels, combined
with the use of location-specific distance-based approached can
support the long-term transition to zero-emissions mobility
while maintaining revenue from transport taxes. Location-
specific distance-based charges are also well suited to manage

19. the impacts of disruptive technologies in road transport,
including those related to electrification, automation and shared
mobility services.
The EV uptake and related battery production requirements
imply bigger demand for new materials in the automotive
sector, requiring increased attention to raw materials supply.
Traceability and transparency of raw material supply chains are
key instruments to help address the criticalities associated with
raw material supply by fostering sustainable sourcing of
minerals. The development of binding regulatory frameworks is
important to ensure that international multi-stakeholder co-
operation can effectively address these challenges. The battery
end-of-life management – including second-life applications of
automotive batteries, standards for battery waste management
and environmental requirements on battery design – is also
crucial to reduce the volumes of critical raw materials needed
for batteries and to limit risks of shortages.
Absent adjustments to current transport-related taxation
schemes, the increasing uptake of electric vehicles has the
potential to change the tax revenue base derived from vehicle
and fuel taxes. Gradually increasing taxes on carbon-intensive
fuels, combined with the use of location-specific distance-based
charges can support the long-term transition to zero-emissions
mobility while maintaining revenue from taxes on
transportation.
