| Year | Term | Explanation |
|---|---|---|
| 2018 | Opportunity Cost | The cost of an alternative that must be forgone to pursue a particular action. A key concept in economics representing the trade-off between two or more options. |
2. Important Terms in News
Context: These miscellaneous economic terms cover a wide range of concepts from microeconomics to macroeconomics and are essential for UPSC aspirants to understand.
Microeconomic Concepts
- Cross Elasticity of Demand: An economic concept that explains how the changes in the price of one good can affect the quantity demanded of another good. This relationship can vary depending on whether the two goods are substitutes, complements, or unrelated.
- Law of Supply: States that other factors remain constant, the price and quantity supplied of a good are directly related. When the price paid by buyers for a good rises, suppliers increase the quantity supplied.
- Law of Demand: States that other factors are constant, a good's price and quantity demand are inversely related. When the price of a product increases, the demand for the same product will fall.
- Law of Supply and Demand: According to this theorem, when there is a higher demand for a commodity, the need for its supply will be high and vice versa.
- Law of Diminishing Utility: States that the more we have of a commodity, the less we want to have more of it, as the utility derived from every successive unit of the commodity keeps on declining when more is consumed.
- Opportunity Cost: The cost of an alternative that must be forgone to pursue a particular action. Represents the trade-off between two or more options. (UPSC 2018)
Macroeconomic Concepts & Theories
- Gresham's Law: A principle that states that "bad money drives out good". The law observes that legally overvalued currency will drive legally undervalued currency out of circulation. Observes the effects of currency debasement.
- Gini Index (Lorenz Curve): A measure of the distribution of income across a population. A higher Gini index indicates greater inequality. The Lorenz curve is a graphical representation of the distribution of income or wealth.
- Hysteresis: In economics, a situation arises when any historical event affects the future economic path. Any economic disturbance will lead to a trickle-down effect, and the problem will persist for long. This rolling-down impact is known as the hysteresis effect.
- Laissez-Faire: An economic theory that opposes any government intervention in business affairs.
- Marginal Propensity to Consume (MPC): Refers to the proportion of extra income that a person spends instead of saving.
- Marginal Propensity to Save (MPS): An economic measure of how savings change with respect to changes in income.
- Paradox of Thrift: When individuals try to save more during an economic recession, it leads to a fall in aggregate demand and, hence, in economic growth.
- Pigou Effect: Refers to the relationship between consumption, wealth, employment, and output during periods of deflation. States that when prices deflate, employment (and thus output) will increase due to an increase in wealth (which increases consumption).
- Ricardian Equivalence: The theory that consumers are forward-looking and anticipate that government borrowing today will mean a tax increase in the future to repay the debt. They will adjust consumption accordingly to have the same effect on the economy as a tax increase today.
- Sharpe Ratio: Compares the return on an investment with its risk. A mathematical expression of the insight that excess returns over time may signify more volatility and risk rather than investing skill.
Digital & Gig Economy
- Digital Creator Economy: An ecosystem involving creators, audiences, digital platforms, marketers, and agencies, interconnected through the exchange of content, money, or goods and services.
- Digital Public Infrastructure (DPI): A set of shared digital systems which are secure and interoperable, built on open standards and specifications to deliver and provide equitable access to public and/or private services at a societal scale.
- Gig Economy: A free market system in which temporary positions are common and organizations contract with independent workers for short-term engagements.
- Gig Workers: Those engaged in livelihood outside the traditional employer-employee arrangement. Broadly classified into:
- Platform Gig Workers: Those whose work is based on online software, apps, or digital platforms such as food aggregator platforms (Zomato, Swiggy, Ola, and others).
- Non-Platform Gig Workers: Generally casual waged and own-account workers in the conventional sector, engaged part-time or full-time.
Legal & Rights Concepts
- Performer's Rights and Tax: Legal rights granted to actors, singers, musicians, dancers, and other performers for their creative works. The first significant development came with the adoption of the Rome Convention in 1961. In India, performer rights were recognised under the Copyright Act of 1957 in the year 1994.
Energy & Market Concepts
- Market Coupling: Refers to the forming of a single power trading entity owned by the government. Under it, buy and sell bids from all power exchanges in the country will be aggregated and matched to discover a uniform power price or market clearing price (MCP).
