Hard Level – GK Questions

Arthur Okun's empirical law highlights the severe macroeconomic cost of unemployment. It quantifies the loss in national output resulting from idle labor resources, demonstrating that high unemployment not only causes social distress but also creates a massive negative output gap relative to the economy's full-employment potential.

Skewflation poses a unique challenge for central banks because standard monetary tightening (raising interest rates) might successfully curb general demand but fail to address supply-side bottlenecks in specific sectors like agriculture. This can lead to a situation where raising rates unnecessarily stifles overall economic growth without solving the targeted inflation.

The C2 cost is the most comprehensive measure of production costs, including imputed rent on owned land and interest on owned capital assets, in addition to actual paid-out costs (A2) and family labor (FL). While the government currently uses the A2+FL formula for MSP, the Swaminathan Commission advocated for the C2+50% formula to ensure true economic viability for farmers.

Coined by Garrett Hardin, this concept applies to common-pool resources like fisheries or grazing land, which are rivalrous (one's use reduces another's) but non-excludable. Without property rights or regulation, individuals overconsume, leading to the eventual destruction of the resource for everyone.

Industries like water supply, electricity grids, and railways are natural monopolies because duplicating the massive infrastructure network for multiple competing firms would be wildly inefficient and costly. Therefore, they are typically either state-owned or heavily regulated by the government.

Proposed by Keynes, the paradox illustrates that while saving is virtuous for an individual, a collective increase in savings reduces consumption. This drops aggregate demand, leading to lower production, job losses, and ultimately a lower total income, meaning the economy's actual total savings end up falling.

Currency depreciation means it takes fewer units of foreign currency to buy the domestic currency. Consequently, domestic goods become cheaper in international markets, boosting export volumes. However, this relies on the Marshall-Lerner condition, which requires the sum of export and import elasticities to be greater than one.

The OEA compiles and publishes the Wholesale Price Index (WPI). The Consumer Price Index (CPI) is compiled by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI), while the Labour Bureau compiles CPI for specific industrial and agricultural workers.

Prior to this, the RBI used the Wholesale Price Index (WPI) to gauge inflation. The Urjit Patel Committee argued that CPI better reflects the actual cost of living for consumers and recommended shifting the monetary policy focus entirely to CPI, leading to the formalization of the inflation-targeting framework.

The second Narasimham Committee laid the blueprint for strengthening the Indian banking system. It recommended tighter income recognition and provisioning norms, the reduction of the SLR and CRR, and the deregulation of interest rates to make Indian banks globally competitive.

Within the overall 40% PSL target, banks must allocate at least 18% of ANBC specifically to agriculture. Furthermore, 10% of ANBC must be directed towards small and marginal farmers, ensuring that the most vulnerable agrarian sections receive adequate institutional credit.

By buying long-term bonds, the RBI increases their price and lowers their yield (interest rate), making long-term borrowing cheaper for infrastructure and housing. Simultaneously selling short-term paper prevents excess overall liquidity from building up in the system.

Simon Kuznets theorized that as an economy develops from agrarian to industrial, inequality initially rises as people move to higher-paying urban jobs. However, as the economy matures and welfare mechanisms, education, and democratization spread, inequality eventually decreases.

23. Arthur Lewis proposed the dual-sector model, explaining how developing economies can grow by transferring 'surplus' or disguisedly unemployed labor from the subsistence agricultural sector to the higher-productivity industrial sector, keeping wages low and profits high for reinvestment.

The reverse is true. The Harrod-Domar model posits that economic growth depends heavily on the national savings rate and the capital-output ratio, assuming fixed technology. The Solow-Swan model introduced exogenous technological progress as the critical factor for sustaining long-term per capita growth beyond mere capital accumulation.

ICOR indicates how much additional capital is needed to produce one additional unit of output. A lower ICOR signifies high efficiency and productivity of investments, whereas a high ICOR indicates inefficiency, poor infrastructure, or technological bottlenecks in the economy.

First-degree (or perfect) price discrimination allows the monopolist to capture the entire consumer surplus, converting it into producer surplus. While theoretically efficient, it is practically impossible to implement because it requires perfect knowledge of every consumer's reservation price.

Named after mathematician John Nash, this equilibrium concept describes a stable state in a strategic interaction. Each player is making the best possible decision they can, taking into account the decisions of the other players, meaning no unilateral deviation is profitable.

Ronald Coase argued that the initial allocation of property rights doesn't matter for efficiency, as long as rights are clear and parties can negotiate costlessly. They will naturally trade rights until the externality is internalized at the socially optimal level.

The reverse is true. Adverse selection happens before the transaction (e.g., high-risk individuals are more likely to buy insurance). Moral hazard occurs after the transaction, when one party changes their behavior and takes more risks because they are protected from the consequences (e.g., driving recklessly after buying full-coverage insurance).
