Question A: By enabling women’s life choices about education, work and family, the contraceptive pill made a substantial contribution to closing gender gaps in the labor market for professionals.

Question B: Gender gaps in today’s labor market arise less from differences in educational and occupational choices than from the differential career impact of parenthood and social norms around men's and women’s roles in childrearing.

Question C: The gender gap in pay would be substantially reduced if firms had fewer incentives to offer disproportionate rewards to individuals who work long and/or inflexible hours.

Question A: The EU's taxonomy for sustainable activities - a classification system that defines criteria for economic activities that are aligned with a net zero trajectory by 2050 and the broader environmental goals other than climate - is an effective way to steer greener investment and the energy transition by firms and financial institutions.


Details on the taxonomy are here:
https://finance.ec.europa.eu/sustainable-finance/tools-and-standards/eu-taxonomy-sustainable-activities_en

Question B: The oil price cap imposed by the G7/EU countries will not have a substantial effect on the world oil price (such as the Brent crude benchmark).

Question A: The increasing share of income and wealth among the richest people in a number of advanced countries is giving significantly more political power to the wealthy.

Question B: The increasing share of income and wealth among the richest people in a number of advanced countries is having a significantly negative effect on intergenerational social mobility.

Question C: The increasing share of income and wealth among the richest people in a number of advanced countries is a major threat to capitalism.

Question A: A windfall tax on the excess profits of large oil and gas companies – with the revenue rebated to households – would be an efficient way to provide temporary relief for the average household in European countries from rising energy costs.

Question B: Fiscal measures putting a cap on consumer energy prices would be a more appropriate immediate response to increased inflation in the euro area than raising interest rates.

Stablecoins that are not fully backed by either central bank reserves or government securities with minimal price volatility are inherently vulnerable to runs.

High tariffs imposed by the European Union on imports of Russian natural gas would be an effective measure to reduce the flow of revenues to Russia while limiting disruption to supplies to Europe.

Rather than using second-round runoffs to settle elections in which no candidate wins a first-round majority, the overall preferences of the electorate would be better reflected by using a single round with ranked-choice voting, in which voters are instructed to rank all of the candidates.

Question A:

Rising energy prices suggest that the European Central Bank and the Federal Reserve will have to increase interest rates faster than they intended to before the invasion.

Question B: Increased public spending by European countries to accommodate larger defense budgets, migration inflows and accelerated investment in alternative energy sources would be better financed mostly through taxes, rather than debt.

Question A:

High volatility in the prices of crypto assets such as Bitcoin, Dogecoin, and Ethereum largely reflects movements in investor sentiment rather than news about potential sources of fundamental value (such as possible applications, or use in illicit transactions).

Question B: Given existing regulation of the financial system, as crypto assets grow in value and become more connected to the rest of the system, the fluctuations in their valuations will pose a serious risk to financial stability in advanced economies.

Question C: Private unbacked crypto assets serve no important economic purpose.

Question A:

Firms’ incentives to reduce costs by sourcing inputs and products abroad have caused many European industries to become more vulnerable to supply chain disruptions.

Question B: Private firms have inadequate incentives to make investments to reduce the risk that disruptions in the supply of imports will cause shortages and raise domestic prices.

Question C: Prioritisation of efficiency over resilience in global supply chains makes current disruptions likely to continue beyond 2022.

Question A:

Given the centrality of semiconductors to the manufacturing of many products, securing reliable supplies should be a key strategic objective of EU and national policy.

Question C: Public support at EU and national level for investment along the value chain for semiconductors, including production, would be the most effective way to ensure security of supply.

Question A:

Even without renewed Covid-19 restrictions, uncertainty about the health threat from the Omicron variant is likely to deliver a significant hit to economic activity from now through the first half of 2022.

Question B: If world vaccine supply continues to be limited, global social welfare would rise by more if those vaccines were made widely available across Africa (with support for effective delivery) rather than accelerating booster vaccinations in rich countries.

Question C: Imposing travel bans on countries where new Covid-19 variants are discovered will make it less likely that countries will reveal new variants to the rest of the world.

Question A: Voluntary national targets are unlikely to be an effective mechanism for achieving sharp reductions in greenhouse gas emissions.

Question B: Agreement on a significant global price floor for all carbon emissions would be an effective step towards achieving sharp reductions in emissions.

Question B: For emerging and developing economies open to the world capital market, a flexible exchange rate confers little advantage over a pegged exchange rate in terms of economic stability.

Question C: The key feature making the US a more natural optimum currency area than the euro area is higher labor mobility.

Question A: Reliable Covid-19 vaccines will reach developing countries more quickly if the rich countries pay the pharmaceutical companies at prevailing prices to manufacture and distribute the vaccines (or to license production and support licensees), rather than waiving patent protection.

Question B: The benefits to the US, Canada, Europe, Japan and other rich countries of paying for 12 billion doses of Covid vaccines at prevailing prices and providing them for free to the rest of the world exceed the costs that the rich countries would incur.

Question A: The Bank for International Settlements defines a central bank digital currency as follows: ‘In simple terms, a central bank digital currency (CBDC) would be a digital banknote. It could be used by individuals to pay businesses, shops or each other (a 'retail CBDC'), or between financial institutions to settle trades in financial markets (a ‘wholesale CBDC').

For developed countries, a central bank digital currency that is available to the public at large would offer social benefits that exceed the associated costs or risks.

Question B: Central banks that do not introduce their own digital money risk losing the ability to conduct effective monetary policy.

Question C: The introduction of a central bank digital currency is unlikely to have major effects on the economy.

Question A: Removing intellectual property protections on Covid-19 vaccines would substantially improve availability of the vaccines in developing countries.

Question B: Removing intellectual property protections on Covid-19 vaccines would have a negative impact on vaccine development efforts for future variants of SARS-CoV-2 or for the next pandemic.

Question C: Without an international agreement that facilitates vaccine trade, countries’ incentives to limit exports of vaccines and/or key production inputs are likely to prolong the adverse effects of the pandemic in advanced countries.

Question A: Allowing short selling of financial securities, such as stocks and government bonds, leads to prices that, on average, are closer to their fundamental values.

Question B: Requiring investors to disclose short positions in a stock at the equivalent threshold as they are required to do for long positions would result in significantly less short selling.

Question C: Regulatory restrictions on short selling - such as no naked shorts, temporary bans in times of crisis - make it difficult for optimists and pessimists to have equal influence on asset prices.

Question A: EU Covid-19 vaccination efforts are significantly behind those of Israel, Serbia, the UK and the US.

Offering substantially higher prices per dose would have resulted in larger capacity investments by vaccine makers and accelerated distribution in Europe significantly.

Question B: In the current situation, paying for more production capacity would be better than offering higher prices for vaccines.

Question C: If the EU started paying prices above 100 euros per dose, it would on net reduce the cost of the pandemic to the EU via more lives saved and shorter lockdowns.

Question A: Policies that aim to reduce obesity by increasing incentives for physical activity would be more welfare-improving than policies that increase the financial costs of consuming calories.

Question B: A ban on advertising junk foods (those that are high in sugar, salt and fat) would be an effective policy to reduce child obesity.

Question C: Setting targets for schools to reduce obesity (e.g. by diverting financial resources to improve school meals or add cookery to the curriculum) would reduce social welfare because schools in deprived areas, where obesity is higher, are already struggling to deliver the core curriculum.

Question A: The current US federal minimum wage is $7.25 per hour. States can choose whether to have a higher minimum - and many do.

A federal minimum wage of $15 per hour would lower employment for low-wage workers in many states.

Question B: A federal minimum wage that is pegged to state and/or local conditions such as the cost of living would be preferable to the current arrangements that give states a role in setting the policy.

Question A: A wealth tax would be an effective way to reduce inequality.

Question B: A wealth tax in a form discussed in the UK (where individuals could be taxed a percentage of their net worth over £750,000, excluding any personal pension savings and their main home) would be an effective way to improve public finances after the Covid-19 crisis.

Question C: A public policy goal that could be accomplished with a well-enforced wealth tax could be accomplished at lower cost with modifications to existing taxes, such as income tax, capital gains tax, inheritance tax and property tax.

Question A: Google's dominance of the market for internet search arose mainly from a combination of economies of scale and a quality algorithm.

Question B: In light of Google’s dominance, its current operating practices could have a substantial negative effect on social welfare in the long run.

Question C: The nature of the market dominance of technology giants in the digital economy warrants either the imposition of some kind of regulation or a fundamental change in antitrust policy.

The practical application of auction theory to the licensing of rights to use public assets like radiospectrum and other natural resources has generated substantially higher government revenues and better allocative efficiency worldwide than would have happened under previous arrangements.
