Introduction [5 Marks]
Part A: Microeconomics.
Understanding the Most Famous Monopolies
Government regulation of early American monopolies was initially absent. However, the creation of antitrust regulation in the United States, in the form of the 1890 Sherman Antitrust Act, led to the eventual dismantling and restructuring of Standard Oil and American Tobacco by 1911. Like many antitrust cases brought against companies even today, it took several years for these first cases to navigate through the court system Unlike Standard Oil and American Tobacco, U.S. Steel was challenged, but not found to be the sole supplier of steel to the U.S. market. However, it continued to possess considerable market share for many years. In 2018, U.S. Steel was the 26th-largest producer of steel in the world, according to the World Steel Association.
More Modern Times
A more recent monopoly to have experienced the same fate as Standard Oil and American Tobacco is the American Telephone and Telegraph Company (AT&T). In 1982, AT&T was found to be in violation of U.S. antitrust law while acting as the sole supplier of telephone services to the country. As a result, it was forced to split into six subsidiaries, known as Baby Bells
A good example of a near-monopoly from very recent history is the De Beers Group, the best-known diamond mining, production, and retail company in the world. De Beers was close to a true monopoly for almost a century, but due to a variety of market and regulatory factors, it has seen its market share go from over 80% in the late 1980s to around 35% in 2019.While several U.S. companies in sectors like technology, consumer products, and food and beverage manufacturing have been accused of being monopolies in the media and some in courts, they have rarely been proven so.
The Role of Nationalization
Most monopolies that exist today do not necessarily dominate an entire global industry. Rather, they control major assets in one country or region. This process is called nationalization, which occurs most often in the energy, transportation, and banking sectors. The largest such example of a nationalized major asset is Saudi Arabia's Saudi Aramco, the nation's state-owned oil and natural gas company .Most monopolies that exist today do not necessarily dominate an entire global It is arguably the single most valuable company in the world at $1.7 trillion as of its late 2019 IPO valuation
The Bottom Line
For everything, there is a season, even for monopolies. Monopolies often can help a country or region build or shore up its infrastructure quickly, efficiently, and effectively. But when any company becomes too dominant, leaving little room for competition, service, quality, and consumer wallets can suffer. That's where antitrust laws come in.

Part B: Macroeconomics:
Question Six: [15 Marks]
“The oil Price run-up of 2007-08 was caused by strong demand confronting stagnating world production. Although the causes were different, the consequences for the economy appear to have been very similar to those observed in earlier episodes, with significant effects on overall consumption spending and purchases of domestic automobiles in particular. The experience of 2007-08 should thus be added to the list of recessions to which oil prices appear to have made a material contribution.”

Question Seven: [10 Marks]
The following was released by the Bank of England reflecting on monetary policy on 17th of Sept 2020
The Bank of England’s Monetary Policy Committee (MPC) sets monetary policy to meet the 2% inflation target, and in a way that helps to sustain growth and employment. In that context, its challenge at present is to respond to the economic and financial impact of the Covid-19 pandemic. At its meeting ending on 16 September 2020, the MPC voted unanimously to maintain Bank Rate at 0.1%. The Committee voted unanimously for the Bank of England to continue with its existing programmes of UK government bond and sterling non-financial investment-grade corporate bond purchases, financed by the issuance of central bank reserves, maintaining the target for the total stock of these purchases at £745 billion.
The outlook for the economy remains unusually uncertain. The MPC’s central projections in the August Monetary Policy Report assumed that the direct impact of Covid-19 on the economy would dissipate gradually. They were also conditioned on the assumption of an immediate, orderly move to a comprehensive free trade agreement with the European Union on 1 January 2021. Conditional on those assumptions, UK GDP was projected to continue to recover. Activity was also supported by substantial fiscal and monetary policy actions. Nonetheless, the recovery in demand took time as health concerns were expected to drag on activity. The unemployment rate was projected to rise markedly, consistent with a material degree of spare capacity, before declining gradually. Conditioned on prevailing market yields, CPI inflation was expected to be around 2% in two years’ time.
Indicators of global activity have been broadly in line with the Committee’s expectations at the time of the August MPC meeting. The sterling exchange rate index has fallen by around 2%, in part reflecting recent Brexit developments.
