Macroeconomic Model
A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices. Macroeconomic models may be logical, mathematical, and/or computational; the different types of macroeconomic models serve different purposes and have different advantages and disadvantages. Macroeconomic models may be used to clarify and illustrate basic theoretical principles; they may be used to test, compare, and quantify different macroeconomic theories; they may be used to produce "what if" scenarios (usually to predict the effects of changes in monetary, fiscal, or other macroeconomic policies); and they may be used to generate economic forecasts. Thus, macroeconomic models are widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparative Statics
In economics, comparative statics is the comparison of two different economic outcomes, before and after a change in some underlying exogenous variable, exogenous parameter. As a type of ''static analysis'' it compares two different economic equilibrium, equilibrium states, after the process of adjustment (if any). It does not study the motion towards equilibrium, nor the process of the change itself. Comparative statics is commonly used to study changes in supply and demand when analyzing a single Market (economics), market, and to study changes in monetary policy, monetary or fiscal policy when analyzing the whole macroeconomics, economy. Comparative statics is a tool of analysis in microeconomics (including general equilibrium analysis) and macroeconomics. Comparative statics was formalized by Sir John Richard Hicks, John R. Hicks (1939) and Paul A. Samuelson (1947) (Kehoe, 1987, p. 517) but was presented graphically from at least the 1870s. For models of stable equili ...

Dynamical System
In mathematics, a dynamical system is a system in which a Function (mathematics), function describes the time dependence of a Point (geometry), point in an ambient space, such as in a parametric curve. Examples include the mathematical models that describe the swinging of a clock pendulum, fluid dynamics, the flow of water in a pipe, the Brownian motion, random motion of particles in the air, and population dynamics, the number of fish each springtime in a lake. The most general definition unifies several concepts in mathematics such as ordinary differential equations and ergodic theory by allowing different choices of the space and how time is measured. Time can be measured by integers, by real number, real or complex numbers or can be a more general algebraic object, losing the memory of its physical origin, and the space may be a manifold or simply a Set (mathematics), set, without the need of a Differentiability, smooth space-time structure defined on it. At any given time, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project LINK
Wharton Econometric Forecasting Associates, Inc (WEFA Inc) was an economics forecasting and consulting organization founded by Nobel Prize winner Lawrence Klein. WEFA Inc was a spinoff of the Wharton School of the University of Pennsylvania, where Klein taught. WEFA Inc traced an interesting path (see below for full details) from its predecessor in 1961 (the Economic Research Unit, discussed below), its initial launch in 1969 (as Wharton Econometric Forecasting Associates Inc), to its ultimate merger with DRI (formerly Data Resources Inc.) forming Global Insight in 2001, and subsequent to that, Global Insight's acquisition in 2008 by IHS Inc. Origins Incorporated in 1969 by the Trustees of the University of Pennsylvania as a "not for profit" organization, WEFA Inc was an outgrowth of the Economics Research Unit (ERU) located in the economics department of the University of Pennsylvania.

Jan Tinbergen
Jan Tinbergen ( , ; 12 April 1903 – 9 June 1994) was a Dutch economist who was awarded the first Nobel Memorial Prize in Economic Sciences in 1969, which he shared with Ragnar Frisch for having developed and applied dynamic models for the analysis of economic processes. He is widely considered to be one of the most influential economists of the 20th century and one of the founding fathers of econometrics.Magnus, Jan & Mary S. Morgan (1987) ''The ET Interview: Professor J. Tinbergen'' in: 'Econometric Theory 3, 1987, 117-142. His important contributions to econometrics include the development of the first macroeconometric models, the solution of the identification problem, and the understanding of dynamic models. Tinbergen was a founding trustee of Economists for Peace and Security. In 1945, he founded the Bureau for Economic Policy Analysis (CPB) and was the agency's first director.

Review Of Economics And Statistics
''The Review of Economics and Statistics'' is a peer-reviewed academic journal that covers applied economics, with specific relevance to the scope of econometrics. The editors-in-chief are Will Dobbie (Harvard University) and Raymond Fisman (Boston University). The journal is over 100 hundred years old.

Adaptive Expectations
In economics, adaptive expectations is a hypothesized process by which people form their expectations about what will happen in the future based on what has happened in the past. For example, if people want to create an expectation of the inflation rate in the future, they can refer to past inflation rates to infer some consistencies and could derive a more accurate expectation the more years they consider. One simple version of adaptive expectations is stated in the following equation, where p^e is the next year's rate of inflation that is currently expected; p^e_ is this year's rate of inflation that was expected last year; and p is this year's actual rate of inflation: :p^e = p^_ + \lambda (p - p^_) where \lambda is between 0 and 1. This says that current expectations of future inflation reflect past expectations and an "error-adjustment" term, in which current expectations are raised (or lowered) according to the gap between actual inflation and previous expectations.
