Through the external economies of scale, the entry of new firms benefits all existing competitors as it creates greater competition and also reduces the average cost for all firms as opposed to internal economies of scale which only allows benefits to the individual firm. [45] Advantages that arise from external economies of scale include;
Marc Melitz and Pol Antràs started a new trend in the study of international trade. While new trade theory put emphasis on the growing trend of intermediate goods, this new trend emphasizes firm level differences in the same industry of the same country and this new trend is frequently called 'new' new trade theory (NNTT).
Through trade theory, the home market effect is derived from models with returns to scale and transportation costs. When it is cheaper for an industry to operate in a single country because of returns to scale, an industry will base itself in the country where most of its products are consumed in order to minimize transportation costs.

[ a ] A single market allows for people, goods, services and capital to move around a union as freely as they do within a single country – instead of being obstructed by national borders and barriers as they were in the past.
Goldman Sachs Economic Research estimates that long-term tariffs on imports from Canada and Mexico could raise core inflation – measured by the PCE – by 0.7% and reduce economic growth by 0.4%.
A company may do this via internal expansion or through mergers and acquisitions. [1] [2] [3] The process can lead to monopoly if a company captures the vast majority of the market for that product or service. [3] Benefits of horizontal integration include: increasing economies of scale, expanding an existing market, and improving product ...
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 ...
Internal diseconomies of scale can be avoided by increasing industry output by increasing the number of plants without increasing the scale of the plant. External economies of scale are also either technical or pecuniary, but in this case are due to the aggregate behaviour of the industry, and refer to the size of output of the industry as a whole.
