The Inflation Definition Economics

The best-known indicator of inflation is the consumer price index (CPI), which measures the percent change in prices for the basket of goods and services consumed by households. Statistical agencies measure inflation by first determining the present value of the basket of different goods and services consumed by households, called a price index.

The increase in the overall level of prices, which is the core of inflation, is measured using the price index, which combines prices for different goods and services. Key Takeaways Inflation is the rate at which the value of the currency falls, and the resulting increase in the general level of prices for goods and services.

Inflation refers to the degree at which the overall or average level of prices of goods is rising, and consequently, the extent at which the purchasing power of a unit of currency is declining. Inflation refers to a widespread increase in prices of goods and services throughout an economy over time, which reduces the purchasing power of consumers and businesses alike. Inflation is a loss in the purchasing power of currency units, like dollars, typically expressed as an overall increase in the prices of goods and services….We have a variety of measures of inflation, but none provides a truly reliable indicator of inflation at a particular point in time.

This is called deflation, and it occurs when inflation is not at work, and prices of goods are not stagnant. Over time, inflation actually makes the currency less valuable, since the same amount of money will buy less goods. As inflation increases, consumer spending falls, because as prices increase, people cannot afford to buy as much.

Higher Inflation may also Spur Spending

Higher inflation may also spur spending, because consumers will try to purchase goods as fast as possible before they increase in value even more. During inflation, V may increase because people are racing to buy goods before prices increase too much–so the money supply may be turned over more quickly–and by holding constant M and Q, P may increase, as well, leading to still higher prices and more inflation. In other words, as the money supply increases, without any changes to speed or quantity, the price level should increase, too — we call that inflation.

Inflation can be defined as either a steady or uninterrupted rise in the overall price level, or, alternatively, as a steady or uninterrupted decline in the value of money. A more precise definition of inflation is a sustained rise in the general price level of the economy. Inflation is defined as the rate at which prices of products and services change in a given period of time, typically one year.

The annual inflation rate is the price of that basket in a given month relative to its price the same month one year earlier. Every quarter, ABS computes the change in price for each commodity since the previous quarter, and adds these together to calculate an inflation rate for the whole basket CPI. Both the types of goods and services included in the basket, and the weighted prices used in inflation measures, will be changed over time to match a changing market.

Indicators of Basic Inflation

Indicators of basic inflation exclude items which experience especially large changes in prices (either often or within any given quarter). The measure of the inflation rate excluding volatile items always removes the same items, whereas items removed from the average trim and average weight may vary each quarter, depending on which items had especially large price changes. While the CPI measures changes in prices, CPI-related inflation is change in the expenditures households need to make in order to maintain a given standard of living.

The average spending habits of all households combined determines how much weight various products and services receive in measuring inflation. Expressed as a percentage, inflation takes a number of factors into account, ranging from broader measures such as the total cost of living in the country, to more specific needs such as groceries, fuel, and heating costs–even the price of haircuts. Inflation seeks to measure the total effect of price changes on a diverse range of products and services, and allows a unitary value to represent an increase in the level of prices for goods and services across the economy over time.

Inflation can also be used to describe a rise in price levels in a narrower set of assets, goods, or services in the economy, such as commodities (including food, fuel, metals), tangible assets (such as real estate), financial assets (such as stocks, bonds), services (such as entertainment and healthcare), or labor. Inflation built up occurs when a countrys prices for commodities increase, then workers demand higher wages in order to keep up with, or maintain, their standard of living because of higher costs for the final products. In response, businesses usually increase the prices of their products or services to compensate for inflation, meaning consumers absorb those price increases.

Serial Shift of Purchasing Power and Prices

This serial shift of purchasing power and prices (known as the Cantillon Effect) means the inflationary process not only increases the overall price level over time, it also skews relative prices, wages, and rates of return along the way. Creep inflation is virtually unheard of throughout the economy, while galloping inflation illustrates a rapid rise in prices–one that may be difficult to contain. The adverse effects of inflation include increased opportunity costs associated with holding cash, uncertainty about future inflation, which may deter investments and savings, and, if inflation is sufficiently rapid, a shortage of goods, as consumers start to stockpile out of fear of future price increases.

For example, when the money supply expansion causes a speculative oil price boom, energy costs for various uses can increase and contribute to higher consumer prices, which are reflected in the different measures of inflation. Even moderate rates of inflation mean money held in cash or in low-apy bank accounts loses purchasing power over time. People usually think of inflation in negative terms: it is when prices go up, things get more expensive, and people cannot afford to buy those things.

Inflation can be measured through a variety of indexes, and the most commonly used indices in the U.S. are the consumer price index (CPI) and the wholesale price index (WPI).
