Aruoba-Diebold-Scotti Index
The Aruoba-Diebold-Scotti Business Conditions Index ("ADS Index" ) is a coincident business cycle Economic indicator, indicator used in macroeconomics in the United States. The index measures business activity, which may be correlated with periods of expansion and contraction in the Economy of the United States, economy. The primary and novel function of the ADS index stems from its use of high-frequency economic data and subsequent high-frequency updating, opposed to the traditionally highly-lagged and infrequently-published macroeconomic data such as Gross domestic product, GDP. Development The ADS index was first introduced by the authors, including Francis X. Diebold, Francis Diebold, in March 2007 and published in October 2008, but the index is retroactively calculated back to March 1960. While other economic nowcasting often estimates GDP or inflation, the ADS index exists as an stand-alone series. This is in part due to the business cycle not tied to a single variable, such ...

Business Cycle
Business cycles are intervals of expansion followed by recession in economic activity. These changes have implications for the welfare of the broad population as well as for private institutions. Typically business cycles are measured by examining trends in a broad economic indicator such as Real Gross Domestic Production. Business cycle fluctuations are usually characterized by general upswings and downturns in a span of macroeconomic variables. The individual episodes of expansion/recession occur with changing duration and intensity over time. Typically their periodicity has a wide range from around 2 to 10 years (the technical phrase "stochastic cycle" is often used in statistics to describe this kind of process.) As in arvey, Trimbur, and van Dijk, 2007, ''Journal of Econometrics'' such flexible knowledge about the frequency of business cycles can actually be included in their mathematical study, using a Bayesian statistical paradigm. There are numerous sources of busines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximum Likelihood Estimation
In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of an assumed probability distribution, given some observed data. This is achieved by maximizing a likelihood function so that, under the assumed statistical model, the observed data is most probable. The point in the parameter space that maximizes the likelihood function is called the maximum likelihood estimate. The logic of maximum likelihood is both intuitive and flexible, and as such the method has become a dominant means of statistical inference. If the likelihood function is differentiable, the derivative test for finding maxima can be applied. In some cases, the first-order conditions of the likelihood function can be solved analytically; for instance, the ordinary least squares estimator for a linear regression model maximizes the likelihood when all observed outcomes are assumed to have Normal distributions with the same variance. From the perspective of Bayesian inference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Reserve Bank Of Philadelphia
The Federal Reserve Bank of Philadelphia — also known as the Philadelphia Fed or the Philly Fed — headquartered at 10 Independence Mall in Philadelphia, Pennsylvania, is responsible for the Third District of the Federal Reserve, which covers eastern and central Pennsylvania, the nine southern counties of New Jersey, and Delaware. Its geographical territory is by far the smallest in the system, and its population base is the second-smallest (next to the Federal Reserve Bank of Minneapolis). The current President of the Philadelphia Fed is Patrick T. Harker. The Philadelphia Fed conducts research on both the national and regional economy. Its regional manufacturing index is the second of the regional manufacturing reports released every month (the New York Fed's Empire State Index is now released earlier), but it is still very important to the financial community as a proxy for nationwide manufacturing conditions. The Federal Reserve Bank of Philadelphia publishes a quarterly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transfer Payment
In macroeconomics and finance, a transfer payment (also called a government transfer or simply transfer) is a redistribution of income and wealth by means of the government making a payment, without goods or services being received in return. These payments are considered to be non-exhaustive because they do not directly absorb resources or create output. Examples of transfer payments include welfare, financial aid, social security, and government subsidies for certain businesses. Unlike the exchange transaction which mutually benefits all the parties involved in it, the transfer payment consists of a donor and a recipient, with the donor giving up something of value without receiving anything in return. Transfers can be made both between individuals and entities, such as private companies or governmental bodies. These transactions can be both voluntary or involuntary and are generally motivated either by the altruism of the donor or the malevolence of the recipient. For t ...

Personal Income In The United States
Personal income is an individual's total earnings from wages, investment interest, and other sources. The Bureau of Labor Statistics reported a median weekly personal income of $1,037 for full-time workers in Q1 2022. For the year 2020, the U.S. Census Bureau estimates that the median annual earnings for all workers (aged 15 and over) was $41,535; and more specifically estimates that median annual earnings for those who worked full-time, year round, was $56,287. Income patterns are evident on the basis of age, sex, ethnicity and educational characteristics. In 2005 roughly half of all those with graduate degrees were among the nation's top 15% of income earners. Among different demographics (gender, marital status, ethnicity) for those over the age of 18, median personal income ranged from $3,317 for an unemployed, married Asian American female to $55,935 for a full-time, year-round employed Asian American male. According to the US Census, men tended to have higher income than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Production
Industrial production is a measure of output of the industrial sector of the economy. The industrial sector includes manufacturing, mining, and utilities. Although these sectors contribute only a small portion of gross domestic product (GDP), they are highly sensitive to interest rates and consumer demand. This makes industrial production an important tool for forecasting future GDP and economic performance. Industrial production figures are also used by central banks to measure 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 reduct ..., as high levels of industrial production can lead to uncontrolled levels of consumption and rapid inflation .

Jobless Claims
Initial jobless claims are a data point issued by the U.S. Department of Labor as part of its weekly Unemployment Insurance Weekly Claims Report. Initial jobless claims refer to claims for unemployment benefits filed by unemployed individuals with state unemployment agencies. Initial claims should not be confused with the number of people who actually receive unemployment benefits. For one, initial claims don't include continued claims—individuals who claim benefits for additional weeks of unemployment beyond their initial claim. Additionally, not all claimants will actually receive unemployment benefits. The report is released weekly at 08:30 Eastern Time on Thursdays. The data in the report is collected from state unemployment agencies who report the information to the Department of Labor's Office of Unemployment Insurance. Market impact The weekly release of the report can be a market moving event. The employment situation is extremely important for a macroeconomic analy ...

Yield Curve
In finance, the yield curve is a graph which depicts how the yields on debt instruments - such as bonds - vary as a function of their years remaining to maturity. Typically, the graph's horizontal or x-axis is a time line of months or years remaining to maturity, with the shortest maturity on the left and progressively longer time periods on the right. The vertical or y-axis depicts the annualized yield to maturity. Those who issue and trade in forms of debt, such as loans and bonds, use yield curves to determine their value. Shifts in the shape and slope of the yield curve are thought to be related to investor expectations for the economy and interest rates. Ronald Melicher and Merle Welshans have identified several characteristics of a properly constructed yield curve. It should be based on a set of securities which have differing lengths of time to maturity, and all yields should be calculated as of the same point in time. All securities measured in the yield curve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalman Filter
For statistics and control theory, Kalman filtering, also known as linear quadratic estimation (LQE), is an algorithm that uses a series of measurements observed over time, including statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more accurate than those based on a single measurement alone, by estimating a joint probability distribution over the variables for each timeframe. The filter is named after Rudolf E. Kálmán, who was one of the primary developers of its theory. This digital filter is sometimes termed the ''Stratonovich–Kalman–Bucy filter'' because it is a special case of a more general, nonlinear filter developed somewhat earlier by the Soviet mathematician Ruslan Stratonovich. In fact, some of the special case linear filter's equations appeared in papers by Stratonovich that were published before summer 1960, when Kalman met with Stratonovich during a conference in Moscow. Kalman filtering has numerous te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State-space Representation
In control engineering, a state-space representation is a mathematical model of a physical system as a set of input, output and state variables related by first-order differential equations or difference equations. State variables are variables whose values evolve over time in a way that depends on the values they have at any given time and on the externally imposed values of input variables. Output variables’ values depend on the values of the state variables. The " state space" is the Euclidean space in which the variables on the axes are the state variables. The state of the system can be represented as a ''state vector'' within that space. To abstract from the number of inputs, outputs and states, these variables are expressed as vectors. If the dynamical system is linear, time-invariant, and finite-dimensional, then the differential and algebraic equations may be written in matrix form. The state-space method is characterized by significant algebraization of general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Indicator
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 (quit rate in American English), housing starts, consumer price index (a measure for inflation), Inverted yield curve, consumer leverage ratio, industrial production, bankruptcies, gross domestic product, broadband internet penetration, retail sales, price index, and money supply changes. The leading business cycle dating committee in the United States of America is the private National Bureau of Economic Research. The Bureau of Labor Statistics is the principal fact-finding agency for the U.S. government in the field of labor economics and statistics. Other producers of economic indicators includes the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Factor
In econometrics, a dynamic factor (also known as a diffusion index) is a series which measures the co-movement of many time series. It is used in certain macroeconomic models. A diffusion index is intended to indicate * the changes of the fraction of economic data time series which increase or decrease over the selected time interval, * an increase or decrease in future economic activity, * provide some correlation to the business sentiment of companies. Formally : X_=\Lambda_F_+e_, where F_=(f^_,\dots,f^_) is the vector of lagged factors of the variables in the T \times N matrix X_ (T is the number of observations and N is the number of variables), \Lambda_ are the factor loadings, and e_ is the factor error. History Diffusion indexes were originally designed to help identify business cycle turning points. Example A diffusion index of monthly employment levels across industries measures the degree to which a growth in employment levels in a population is made up of gro ...
