Index Numbers
In economics, statistics, and finance, an index is a number that measures how a group of related data points—like prices, company performance, productivity, or employment—changes over time to track different aspects of economic health from various sources. Consumer-focused indices include the Consumer Price Index (CPI), which shows how retail prices for goods and services shift in a fixed area, aiding adjustments to salaries, bond interest rates, and tax thresholds for inflation. The cost-of-living index (COLI) compares living expenses over time or across places.Turvey, Ralph. (2004) Consumer Price Index Manual: Theory And Practice.' Page 11. Publisher: International Labour Organization. . ''The Economist''’s Big Mac Index uses a Big Mac’s cost to explore currency values and purchasing power. Market performance indices track trends like company value or employment. Stock market indices include the Dow Jones Industrial Average and S&P 500, which primarily cover U.S. ...

Economics
Economics () is a behavioral science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyses what is viewed as basic elements within economy, economies, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and Expenditure, investment expenditure interact; and the factors of production affecting them, such as: Labour (human activity), labour, Capital (economics), capital, Land (economics), land, and Entrepreneurship, enterprise, inflation, economic growth, and public policies that impact gloss ...

Bond Market Index
A bond index or bond market index is a method of measuring the investment performance and characteristics of the bond market. There are numerous indices of differing construction that are designed to measure the aggregate bond market and its various sectors (government, municipal, corporate, etc.) A bond index is computed from the change in market prices and, in the case of a total return index, the interest payments, associated with selected bonds over a specified period of time. Bond indices are used by investors and portfolio managers as a benchmark against which to measure the performance of actively managed bond portfolios, which attempt to outperform the index, and passively managed bond portfolios, that are designed to match the performance of the index. Bond indices are also used in determining the compensation of those who manage bond portfolios on a performance-fee basis. An index is a mathematical construct, so it may not be invested in directly. But many mutual fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Price Index
A price index (''plural'': "price indices" or "price indexes") is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a specific region over a defined time period. It is a statistic designed to measure how these price relatives, as a whole, differ between time periods or geographical locations, often expressed relative to a base period set at 100. Price indices serve multiple purposes. Broad indices, like the Consumer price index, reflect the economy’s general price level or cost of living, while narrower ones, such as the Producer price index, assist producers with pricing and business planning. They can also guide investment decisions by tracking price trends. Types of price indices Some widely recognized price indices include: * Consumer price index – Measures retail price changes for consumer goods and services. * Producer price index – Tracks wholesale price changes for producers. * Wholesal ...

Substitution Bias
Substitution bias describes a possible bias in economic index numbers if they do not incorporate data on consumer expenditures switching from relatively more expensive products to cheaper ones as prices changed. Substitution bias occurs when prices for items change relative to one another. Consider how consumer expenditures are reflected in a consumer price index. Consumers will tend to buy more of the good whose price declined, and less of the now relatively more expensive good. This change in consumption may not be reflected in the longstanding market basket from which a consumer price index A consumer price index (CPI) is a statistical estimate of the level of prices of goods and services bought for consumption purposes by households. It is calculated as the weighted average price of a market basket of Goods, consumer goods and ... is constructed. If a selected good is bought by consumers and it is therefore included in the CPI basket, but when an increase in price of ...

Purchasing Power Parity
Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currency, currencies. PPP is effectively the ratio of the price of a market basket at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the Exchange rate, market exchange rate because of tariffs, and other transaction costs. The purchasing power parity indicator can be used to compare economies regarding their gross domestic product (GDP), labour productivity and actual individual consumption, and in some cases to analyse price convergence and to compare the cost of living between places. The calculation of the PPP, according to the OECD, is made through a ''basket of goods'' that contains a "final product list [that] covers around 3,000 consumer goods and services, 30 occupations in government, 200 types of equipment goods and about ...

Time Series
In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average. A time series is very frequently plotted via a run chart (which is a temporal line chart). Time series are used in statistics, signal processing, pattern recognition, econometrics, mathematical finance, weather forecasting, earthquake prediction, electroencephalography, control engineering, astronomy, communications engineering, and largely in any domain of applied science and engineering which involves temporal measurements. Time series ''analysis'' comprises methods for analyzing time series data in order to extract meaningful statistics and other characteristics of the data. Time series ''f ...

Utility Function
In economics, utility is a measure of a certain person's satisfaction from a certain state of the world. Over time, the term has been used with at least two meanings. * In a Normative economics, normative context, utility refers to a goal or objective that we wish to maximize, i.e., an objective function. This kind of utility bears a closer resemblance to the original Utilitarianism, utilitarian concept, developed by moral philosophers such as Jeremy Bentham and John Stuart Mill. * In a Positive economics, descriptive context, the term refers to an ''apparent'' objective function; such a function is Revealed preference, revealed by a person's behavior, and specifically by their preferences over Lottery (decision theory), lotteries, which can be any quantified choice. The relationship between these two kinds of utility functions has been a source of controversy among both Economics, economists and Ethics, ethicists, with most maintaining that the two are distinct but generally re ...

Cost Of Living
The cost of living is the cost of maintaining a certain standard of living for an individual or a household. Changes in the cost of living over time can be measured in a cost-of-living index. Cost of living calculations are also used to compare the cost of maintaining a certain standard of living in different geographic areas. Differences in the cost of living between locations can be measured in terms of purchasing power parity rates. A sharp rise in the cost of living can trigger a cost of living crisis, where purchasing power is lost and, for some people, their previous lifestyle is no longer affordable. The link between income and health is well-established. People who are facing poverty are less likely to seek regular and professional medical advice, receive dental care, or resolve health issues. The cost of Prescription drug, prescription medicine is often cited as a metric in cost of living research and Consumer price index, consumer price indices. Cost of living pressures ...

Number
A number is a mathematical object used to count, measure, and label. The most basic examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can be represented by symbols, called ''numerals''; for example, "5" is a numeral that represents the number five. As only a relatively small number of symbols can be memorized, basic numerals are commonly organized in a numeral system, which is an organized way to represent any number. The most common numeral system is the Hindu–Arabic numeral system, which allows for the representation of any Integer, non-negative integer using a combination of ten fundamental numeric symbols, called numerical digit, digits. In addition to their use in counting and measuring, numerals are often used for labels (as with telephone numbers), for ordering (as with serial numbers), and for codes (as with ISBNs). In common usage, a ''numeral'' is not clearly dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
