Market Basket
A market basket or commodity bundle is a fixed list of items, in given proportions. Its most common use is to track the progress of inflation in an economy or specific market. That is, to measure the changes in the value of money over time. A market basket is also used with the theory of purchasing price parity to measure the value of money in different places. Consumer basket The most common type of market basket is the basket of consumer goods used to define the Consumer Price Index (CPI). It is a sample of goods and services, offered at the consumer market. In the United States, the sample is determined by Consumer Expenditure Surveys conducted by the Bureau of Labor Statistics. The price collection is conducted by data collectors on a monthly basis, and is processed further by commodity specialists. Examples of categories included in the basket are: * Food and Beverages (breakfast cereal, milk, coffee, chicken, wine, full service meals, snacks) * Housing (rent of primar ...

Inflation
In economics, inflation is an increase in the general price level of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose. The employment cost index is also used for wages in the United States. Most economists agree that high levels of inflation as well as hyperinflation—which have severely disruptive effects on the real economy—are caused by persistent excessive growth in the money supply. Views on low to moderate rates of inflation are more varied. Low or moderate inflation may be attri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Producer Price Index
A producer price index (PPI) is a price index that measures the average changes in prices received by domestic producers for their output. Its importance is being undermined by the steady decline in manufactured goods as a share of spending. Related measures A number of countries that now report a producer price index previously reported a wholesale price index. PPIs around the world United States In the US, the PPI was known as the Wholesale Price Index, or WPI, up to 1978. The PPI is one of the oldest continuous systems of statistical data published by the Bureau of Labor Statistics, as well as one of the oldest economic time series compiled by the Federal Government. The origins of the index can be found in an 1891 U.S. Senate resolution authorizing the Senate Committee on Finance to investigate the effects of the tariff laws "upon the imports and exports, the growth, development, production, and prices of agricultural and manufactured articles at home and abroad ...

Market Basket Analysis
Affinity analysis falls under the umbrella term of data mining which uncovers meaningful correlations between different entities according to their co-occurrence in a data set. In almost all systems and processes, the application of affinity analysis can extract significant knowledge about the unexpected trends. In fact, affinity analysis takes advantages of studying attributes that go together which helps uncover the hidden pattens in a big data through generating association rules. Association rules mining procedure is two-fold: first, it finds all frequent attributes in a data set and, then generates association rules satisfying some predefined criteria, support and confidence, to identify the most important relationships in the frequent itemset. The first step in the process is to count the co-occurrence of attributes in the data set. Next, a subset is created called the frequent itemset. The association rules mining takes the form of ''if'' a condition or feature (A) is presen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Mac Index
The Big Mac Index is a price index published since 1986 by ''The Economist'' as an informal way of measuring the purchasing power parity (PPP) between two currencies and providing a test of the extent to which market exchange rates result in goods costing the same in different countries. It "seeks to make exchange-rate theory a bit more digestible." The index compares the relative price worldwide to purchase the Big Mac, a hamburger sold at McDonald's restaurants. Overview The Big Mac index was introduced in ''The Economist'' in September 1986 by Pam Woodall as a semi-humorous illustration of PPP and has been published by that paper annually since then. Although the Big Mac Index was not intended to be a legitimate tool for exchange rate evaluation, it is now globally recognised and featured in many academic textbooks and reports. The index also gave rise to the word ''burgernomics.'' The theory underpinning the Big Mac index stems from the concept of PPP, which states th ...

Purchasing Power Parity
Purchasing power parity (PPP) is the measurement of prices in different countries that uses the prices of specific goods to compare the absolute purchasing power of the countries' currency, currencies. PPP is effectively the ratio of the price of a basket of goods 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, 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 a ...

GDP Deflator
In economics, the GDP deflator (implicit price deflator) is a measure of the money price of all new, domestically produced, final goods and services in an economy in a year relative to the real value of them. It can be used as a measure of the value of money. GDP stands for gross domestic product, the total monetary value of all final goods and services produced within the territory of a country over a particular period of time (quarterly or annually). Like the consumer price index (CPI), the GDP deflator is a measure of price inflation/deflation with respect to a specific base year; the GDP deflator of the base year itself is equal to 100. Unlike the CPI, the GDP deflator is not based on a fixed basket of goods and services; the "basket" for the GDP deflator is allowed to change from year to year with people's consumption and investment patterns. Calculation Measurement in national accounts In most systems of national accounts the GDP deflator measures the ratio of nominal (o ...

Commodity Price Indices
A commodity price index is a fixed-weight index or (weighted) average of selected commodity prices, which may be based on spot or futures prices. It is designed to be representative of the broad commodity asset class or a specific subset of commodities, such as energy or metals. It is an index that tracks a basket of commodities to measure their performance. These indexes are often traded on exchanges, allowing investors to gain easier access to commodities without having to enter the futures market. The value of these indexes fluctuates based on their underlying commodities, and this value can be traded on an exchange in much the same way as stock index futures. Investors can choose to obtain a passive exposure to these commodity price indices through a total return swap or a commodity index fund. The advantages of a passive commodity index exposure include negative correlation with other asset classes such as equities and bonds, as well as protection against inflation. The disadvan ...

Wholesale Price Index
The Wholesale Price Index (WPI) is the price of a representative basket of wholesale goods. Some countries (like the Philippines) use WPI changes as a central measure of inflation. But now India has adopted new CPI to measure inflation. However, United States now report a producer price index instead. It also influences stock and fixed price markets. The WPI is published by the Economic Adviser in the Ministry of Commerce and Industry. The Wholesale Price Index focuses on the price of goods traded between corporations, rather than the goods bought by consumers, which is measured by the Consumer Price Index. The purpose of the WPI is to monitor price movements that reflect supply and demand in industry, manufacturing and construction. This helps in analyzing both macroeconomic and microeconomic conditions. Calculation The wholesale price index (WPI) is based on the wholesale price of a few relevant commodities of over 240 commodities available. The commodities chosen for the ...
