Economies of scale refers to the cost advantage arise from increasing amount of production. Mathematically, it is a situation in which the firm can double its output for less than doubling the cost, which brings cost advantages. Usually, economies of scale can be represented in connection with a cost-production elasticity, Ec. [3]
Economies of scale is related to and can easily be confused with the theoretical economic notion of returns to scale. Where economies of scale refer to a firm's costs, returns to scale describe the relationship between inputs and outputs in a long-run (all inputs variable) production function.
In mainstream microeconomics, the returns to scale faced by a firm are purely technologically imposed and are not influenced by economic decisions or by market conditions (i.e., conclusions about returns to scale are derived from the specific mathematical structure of the production function in isolation). As production scales up, companies can ...
There are several basic questions that must be answered in order for an economy to run satisfactorily. The scarcity problem, for example, requires answers to basic questions, such as what to produce, how to produce it and who gets what is produced. An economic system is a way of answering these basic questions and different economic systems ...
A common and specific example is the supply-and-demand graph shown at right. This graph shows supply and demand as opposing curves, and the intersection between those curves determines the equilibrium price. An alteration of either supply or demand is shown by displacing the curve to either the left (a decrease in quantity demanded or supplied ...
Economies of scope are "efficiencies formed by variety, not volume" (the latter concept is "economies of scale"). [1] In the field of economics, "economies" is synonymous with cost savings and "scope" is synonymous with broadening production/services through diversified products. Economies of scope is an economic theory stating that average ...
Price systems have been around as long as there has been economic exchanges. The price system has transformed into the system of global capitalism that is present in the early 21st century. [2] The Soviet Union and other Communist states with a centralized planned economy maintained controlled price systems. Whether the ruble or the dollar is ...
In some cases economic predictions in a coincidence of a model merely assert the direction of movement of economic variables, and so the functional relationships are used only stoical in a qualitative sense: for example, if the price of an item increases, then the demand for that item will decrease. For such models, economists often use two ...
