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.
Example of a Ring Star Problem network. The ring star problem (RSP) is a NP-hard problem [1] in combinatorial optimization.In a complete weighted mixed graph, the ring star problem aims to find a minimum cost ring star subgraph formed by a cycle (ring part) and a set of arcs (star part) such that each arc's child node belongs to the cycle and each arc's parent node does not.
Macroeconomics encompasses a variety of concepts and variables, but above all the three central macroeconomic variables are output, unemployment, and inflation. [5]: 39 Besides, the time horizon varies for different types of macroeconomic topics, and this distinction is crucial for many research and policy debates.
[3] [4] They are usually issued once every week or two weeks, and due one or two weeks later. [ 4 ] [ 5 ] If used as part of a summative assessment they are usually given a low weight , [ 6 ] between 10% and 25% of the total mark of the course for all problem sets put together, [ 3 ] [ 5 ] and sometimes will count for nothing if the student ...
Macroeconomic policy instruments are macroeconomic quantities that can be directly controlled by an economic policy maker. [ 1 ] [ 2 ] Instruments can be divided into two subsets: a) monetary policy instruments and b) fiscal policy instruments.
The measurable variables in economics are quantity, quality and distribution. Excluding variables from measurement makes it possible to better focus the measurement on a given variable, yet, this means a more narrow approach. The table was compiled to compare the basic types of measurement.
The original motivation for the development of national accounts and the systematic measurement of employment was the need for accurate measures of aggregate economic activity. This was made more pressing by the Great Depression and as a basis for Keynesian macroeconomic stabilisation policy and wartime economic planning.
The problem there is that the detailed information to do it is often not made available, or is available only at a prohibitive cost. US government statisticians admit frankly that "Unfortunately, the finance sector is one of the more poorly measured sectors in national accounts". [ 12 ]
