The EconForward Glossary
A central reference for the economic vocabulary used across every desk. Each entry is a plain-English definition built to be understood in the time it takes to drink a coffee — sourced, neutral, and connected to the prices you actually pay. These are the foundational terms that let readers tell a factual claim from an opinion and follow the news without a finance degree.
Economics is a language before it is a set of equations. The EconForward glossary is built to teach that language one term at a time, so a reader can open a Federal Reserve press release, a housing affordability report, or a credit-card statement and recognize the forces at work. Each entry names the concept, places it in a category, and explains the mechanism in plain English — the same standard we hold every article to.
The terms below are the load-bearing vocabulary of the three desks: Policy & Current Issues,Behavioral Economics, andEconomics 101. Master these and the rest of the site reads faster — because every explainer here is built to be understood in the time it takes to drink a coffee.
Inflation
A general, sustained rise in the prices of goods and services across an economy, usually measured as a year-over-year percentage change in a price index. As inflation rises, each unit of currency buys fewer goods, eroding purchasing power. Central banks target low, predictable inflation (commonly around 2%) because it oils the gears of credit and wages without destabilizing them.
Interest rate
The price of borrowing money, expressed as a percentage per period. When a central bank raises its policy rate, borrowing becomes more expensive and saving more attractive, which tends to cool spending, investment, and inflation. Lower rates do the reverse.
Opportunity cost
The value of the next-best option you give up when you make a choice. Every decision — a government allocating a budget, a student choosing a major, a family buying a home — has one. Recognizing opportunity cost is the first habit of clear economic thinking.
Supply and demand
The two forces that set prices in a free market. Demand is how much buyers want at each price; supply is how much sellers will provide. Where the two curves cross, the market clears at an equilibrium price and quantity. Shift either curve and the equilibrium moves.
Compound growth
When a quantity grows by a percentage each period, each new period's growth builds on a larger base — so small rate differences compound dramatically over decades. It is the engine behind retirement savings and the reason housing and tuition have outpaced wages.
Externalities
Side effects of a transaction that fall on people who weren't party to it — pollution from a factory, for instance. Because the price doesn't reflect these costs, markets left alone can produce too much of a harmful thing or too little of a beneficial one, which is the classic case for policy intervention.
