In economics, a base period or reference period is a point in time used as a reference point for comparison with other periods. [1] [2] It is generally used as a benchmark for measuring financial or economic data. [3] Base periods typically provide a point of reference for economic studies, consumer demand, and unemployment benefit claims.
In public transport scheduling, the base period is the period of reduced service on weekdays that generally exists between the morning and afternoon rush hours.
The Bureau of Labor Statistics (BLS) is a unit of the United States Department of Labor. It is the principal fact-finding agency for the U.S. government in the broad field of labor economics and statistics and serves as a principal agency of the U.S. Federal Statistical System. The BLS is a governmental statistical agency that collects, processes, analyzes, and disseminates essential statistical data to the American public, the U.S. Congress, other Federal agencies, State and local governments, business, and labor representatives. The BLS also serves as a statistical resource to the United States Department of Labor, and conducts research into how much families need to earn to be able to enjoy a decent standard of living.
An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance. One application of economic indicators is the study of business cycles. Economic indicators include various indices, earnings reports, and economic summaries: for example, the unemployment rate, quits rate, housing starts, consumer price index, consumer leverage ratio, industrial production, bankruptcies, gross domestic product, broadband internet penetration, retail sales, stock market prices, and money supply changes.
A price is the quantity of payment or compensation given by one party to another in return for one unit of goods or services. In some situation, the price of production has a different name. If the product is a "good" in the commercial exchange, the price of this product will likely to be called "price". However, if the product is "service", there will be other possible names for this product's name. For example, the graph on the bottom will show some situations A price is influenced by production costs, supply of the desired item, and demand for the product. A price may be determined by a monopolist or may be imposed on the firm by market conditions.
A consumer price index measures changes in the price level of a weighted average market basket of consumer goods and services purchased by households.
In economics, a discouraged worker is a person of legal employment age who is not actively seeking employment or who has not found employment after long-term unemployment, but who would prefer to be working. This is usually because an individual has given up looking, hence the term "discouraged".
A cost-of-living index is a theoretical price index that measures relative cost of living over time or regions. It is an index that measures differences in the price of goods and services, and allows for substitutions with other items as prices vary.
The PCE price index (PCEPI), also referred to as the PCE deflator, PCE price deflator, or the Implicit Price Deflator for Personal Consumption Expenditures by the BEA, and as the Chain-type Price Index for Personal Consumption Expenditures (CTPIPCE) by the Federal Open Market Committee (FOMC), is a United States-wide indicator of the average increase in prices for all domestic personal consumption. It is benchmarked to a base of 2012 = 100. Using a variety of data including U.S. Consumer Price Index and Producer Price Index prices, it is derived from the largest component of the GDP in the BEA's National Income and Product Accounts, personal consumption expenditures.
A price index is a normalized average of price relatives for a given class of goods or services in a given region, during a given interval of time. It is a statistic designed to help to compare how these price relatives, taken as a whole, differ between time periods or geographical locations.
The official measure of producer prices in the United States is called the Producer Price Index (PPI). It measures average changes in prices received by domestic producers for their output. 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".
The Consumer Expenditure Survey is a Bureau of Labor Statistics (BLS) household survey that collects information on the buying habits of U.S. consumers. The program consists of two components — the Interview Survey and the Diary Survey — each with its own sample. The surveys collect data on expenditures, income, and consumer unit characteristics. In May 2020, the American Association for Public Opinion Research recognized the CE program with its 2020 Policy Impact Award, for joint work by the BLS -- including CE and the Division of Price and Index Number Research -- and the Census Bureau on the Supplemental Poverty thresholds and measure, and the essential contributions these data products have made to the understanding, discussion, and advancement of public policy related to the alleviation of poverty in the United States.
The U.S. Import and Export Price Indexes measure average changes in prices of goods and services that are imported to or exported from the U.S.. The indexes are produced monthly by the International Price Program (IPP) of the Bureau of Labor Statistics. The Import and Export Price Indexes were published quarterly starting in 1974 and monthly since 1989.
The United States Consumer Price Index (CPI) is a set of consumer price indices calculated by the U.S. Bureau of Labor Statistics (BLS). To be precise, the BLS routinely computes many different CPIs that are used for different purposes. Each is a time series measure of the price of consumer goods and services. The BLS publishes the CPI monthly.
In economics, the absence rate is the ratio of workers with absences to total full-time wage and salary employment. In the United States, absences are defined as instances when persons who usually work 35 or more hours per week worked less than 35 hours during the reference week for one of the following reasons: own illness, injury, or medical problems; childcare problems; other family or personal obligations; civic or military duty; and maternity or paternity leave.
In business, the business sector or corporate sector - sometimes popularly called simply "business" - is "the part of the economy made up by companies". It is a subset of the domestic economy, excluding the economic activities of general government, of private households, and of non-profit organizations serving individuals. An alternative analysis of economies, the three-sector theory, subdivides them into:
In the United States, the civilian noninstitutional population refers to people 16 years of age and older residing in the 50 States and the District of Columbia who are not inmates of institutions, and who are not on active duty in the Armed Forces.
In the United States, a complete income reporter is a person who provides values for major sources of income, such as wages and salaries, self-employment income, and social security income.
In economics, a consumer unit is defined as either (1) all members of a particular household who are related by blood, marriage, adoption, or other legal arrangements; (2) a person living alone or sharing a household with others or living as a roomer in a private home or lodging house or in permanent living quarters in a hotel or motel, but who is financially independent; or (3) two or more persons living together who pool their income to make joint expenditure decisions. Financial independence is determined by the three major expense categories: housing, food, and other living expenses. To be considered financially independent, a respondent must provide at least two of the three major expense categories.
In statistics relating to national economies, the indexation of contracts also called "index linking" and "contract escalation" is a procedure when a contract includes a periodic adjustment to the prices paid for the contract provisions based on the level of a nominated price index. The purpose of indexation is to readjust contracts to account for inflation. In the United States, the consumer price index (CPI), producer price index (PPI), and, in the U.S., Employment Cost Index (ECI) are the most frequently used indexes.
In statistics, a deflator is a value that allows data to be measured over time in terms of some base period, usually through a price index, in order to distinguish between changes in the money value of a gross national product (GNP) that come from a change in prices, and changes from a change in physical output. It is the measure of the price level for some quantity. A deflator serves as a price index in which the effects of inflation are nulled. It is the difference between real and nominal GDP.
