In an economic market, production input and output prices are assumed to be set from external factors as the producer is the price taker. Hence, pricing is an important element in the real-world application of production economics. Should the pricing be too high, the production of the product is simply unviable.
[2] [3] Macroeconomists study topics such as output/GDP (gross domestic product) and national income, unemployment (including unemployment rates), price indices and inflation, consumption, saving, investment, energy, international trade, and international finance. Macroeconomics and microeconomics are the two most general fields in economics. [4]
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.
An early example was Jacob Viner, who in his 1936 review of the General Theory said of hoarding that Keynes' attaches great importance to it as a barrier to "full" employment' (p152) while denying (pp158f) that it was capable of having that effect. [39] The theory that hoarding is a cause of unemployment has been the subject of discussion.
An example would be a factory increasing its saleable product, but also increasing its CO 2 production, for the same input increase. [2] The law of diminishing returns is a fundamental principle of both micro and macro economics and it plays a central role in production theory. [5]
The earlier term for the discipline was "political economy", but since the late 19th century, it has commonly been called "economics". [22] The term is ultimately derived from Ancient Greek οἰκονομία (oikonomia) which is a term for the "way (nomos) to run a household (oikos)", or in other words the know-how of an οἰκονομικός (oikonomikos), or "household or homestead manager".
Supply-side economics is a macroeconomic theory postulating that economic growth can be most effectively fostered by lowering taxes, decreasing regulation, and allowing free trade. [1] [2] According to supply-side economics theory, consumers will benefit from greater supply of goods and services at lower prices, and employment will increase. [3]
In economics a trade-off is expressed in terms of the opportunity cost of a particular choice, which is the loss of the most preferred alternative given up. [2] A tradeoff, then, involves a sacrifice that must be made to obtain a certain product, service, or experience, rather than others that could be made or obtained using the same required resources.
