Economics – GK Questions

Named after economist Arthur Pigou, a Pigouvian tax is levied on any market activity that generates negative externalities (costs borne by third parties). The tax aims to internalize the externality, aligning the private cost of production with the true social cost.

The free-rider problem occurs with public goods, where individuals have no incentive to pay for the good because they can consume it without paying, relying on others to foot the bill. This leads to the under-provision of the good by the free market, necessitating government intervention and taxation.

Public goods, like national defense or street lighting, can be consumed by one person without reducing availability to others (non-rival), and no one can be effectively excluded from using them (non-excludable). Because private markets cannot easily charge users, these goods are typically provided by the government.

TRIPS establishes minimum standards for the regulation of various forms of intellectual property (IP) rights, including patents, copyrights, and trademarks, as they apply to global trade. It has been a contentious issue, particularly regarding access to affordable pharmaceuticals in developing nations.

The WTO categorizes agricultural subsidies into Amber (trade-distorting, subject to limits), Blue (production-limiting programs), and Green boxes. Green Box subsidies include government funding for research, pest control, and direct income support decoupled from production, which are fully permitted.

The MFN principle actually requires non-discrimination; if a WTO member grants a special trade favor (like a lower tariff) to one country, it must immediately extend the exact same favor to all other WTO members. Exceptions exist only for Free Trade Agreements or special concessions for developing nations.

Created in 1969 to supplement member countries' official reserves, SDRs are not a currency themselves but a potential claim on the freely usable currencies of IMF members. They were termed 'Paper Gold' because they were initially intended to serve as a substitute for gold in international settlements.

India's forex reserves comprise Foreign Currency Assets, Gold, Special Drawing Rights (SDRs), and the Reserve Tranche Position (RTP) with the IMF. The FCA, which includes investments in US Treasuries and other sovereign bonds, constitutes the vast majority (over 85%) of the total reserves.

While NEER measures the weighted average of a currency relative to a basket of others, REER adjusts this for relative inflation rates. REER is a superior indicator of a country's actual trade competitiveness, as high domestic inflation can erode the benefits of a nominally depreciated currency.

The Current Account records trade in goods and services, plus transfer payments. A deficit means the nation is spending more foreign currency on imports and remittances than it is earning through exports. This deficit must be financed by a surplus in the Capital/Financial Account (e.g., borrowing or FDI).

The Laffer Curve posits that increasing tax rates beyond a certain point will actually decrease total tax revenue due to disincentives to work, tax evasion, and capital flight. It is frequently cited in debates regarding supply-side economics and tax cuts.

Proposed by Arthur Okun, this law states that for every 1% increase in the unemployment rate, a country's GDP will be roughly 2% lower than its potential GDP. It highlights the severe economic cost of joblessness in terms of lost national output.

Stagflation is a portmanteau of stagnation and inflation. It presents a severe dilemma for policymakers because traditional monetary tools used to curb inflation (like raising interest rates) will further depress growth and worsen unemployment.

A.W. Phillips observed that when unemployment is low, wages tend to rise faster, leading to higher inflation. Conversely, high unemployment suppresses wage growth and inflation. However, Milton Friedman later argued this trade-off only exists in the short run, becoming vertical in the long run.

In India's CPI indices, particularly for rural areas, the 'Food and Beverages' category holds the highest weightage (over 54% in CPI-Rural). This reflects the Engel's Law principle, where lower-income rural households spend a disproportionately large share of their income on basic sustenance.

The Office of the Economic Adviser (OEA) compiles the WPI, which tracks price changes in the wholesale market for a basket of 697 items. The base year was updated from 2004-05 to 2011-12 to align it with the base year of the Consumer Price Index (CPI) and GDP series.

Skewflation describes a scenario where prices rise persistently in specific sectors (like food or energy) while remaining stable or even falling in others. This makes monetary policy challenging, as raising interest rates to curb sector-specific inflation might hurt the broader, non-inflating economy.

The base effect is a statistical artifact that occurs when comparing year-on-year inflation data. If prices spiked abnormally in the previous year, the current year's inflation will mathematically look lower even if absolute prices are still rising steadily.

Headline inflation represents the raw, overall inflation rate in the economy, which can be skewed by temporary supply shocks in food or energy. Central banks often focus on core inflation (CPI excluding food and fuel) to make long-term monetary policy decisions, as it reflects sustained demand pressures.

NITI Aayog stands for National Institution for Transforming India. It was established in 2015 to replace the Planning Commission, acting as the premier policy think tank of the Government of India and fostering cooperative federalism through a bottom-up approach.
