Technological advance contributes enormously to economics efficiency. New and better products and processes enable the society to produce more goods at a less price, and produce a higher-valued mix of output.
Technological advance improves productive efficiency by increasing the productivity of inputs and by reducing the average total costs. In enables society to produce the same amount of goods and services by using fewer resources, so that it frees unused resources and produce something else from them. If society needs now more less-expensive goods, process of innovation helps to gain greater quantity of output by sacrifying fewer resources used as input. We may state that process innovation increase productive efficiency: it reduces society’s cost of whatever mix of goods and services it wants and thus it is an important factor that shifts economy’s production possibilities curve by shifting it rightwards.
Technological advance used at production process of various goods increase the allocative efficiency by giving society more desired mix of goods and services. Consumers are willing to buy a new product rather than an older one only if the new one increases the total utility obtained from usage of the same quantity of scarce resources. That’s obviously that new product (and new mix of products) will create a higher total utility for society. That’s why demand for old product declines and demand for the new one increases. High economic profit gained from the new product attracts resources away from less-wanted by society uses to the production of new item. This shifting of resources continues until marginal cost and marginal benefit equalize each other.
However, innovation (either of product or price) may create a monopoly power in the market through patents and through other advantages of being first. When a new monopoly power results from an innovation, society may lose a part of its efficiency it otherwise would have gained from this innovation. The reason is that monopolist may keep product’s price above marginal cost.
Innovation may reduce or even destroy monopoly power by providing competition somewhere it didn’t previously exist. Economic efficiency is enhance after this event occurs, because this new product helps to push the prices down, close to marginal cost and minimum average total costs (ATV). Innovation that leads to greater competition in an industry reduces output-restrictions and monopoly prices.
Innovation may even generate a creative destruction, in which creation of new products and production methods simultaneously destroys the market position of existing monopolies and old ways of doing business.
Examples of creative destructions: movies brought new competition to theatres, which can be shown one at a time, but movies latter were challenged by television, aluminum cans and plastic bottles also displaced glass bottles in many uses, e-mail has challenged the postal service.
Schumpeter says that an innovator will displace any monopolist that no longer delivers superior performance, but this idea is most treated as a wishful thinking nowadays. In this view, idea that creative destruction is automatic, but it neglects somehow the ability of well-established firms to provide shelter by themselves or by lobbying government to do it. This idea ignores differences between legal freedom of entry and economic reality of entering potential newcomers to concentrated industries.
In this case dominant firm(s) may use strategies as buyouts, selective price-cutting, massive advertising to block the entry and competition from existing rivals and appearing innovative firms. Moreover, some firms may be able to persuade government to give them subsidies, tax-break, tariff-protection to strengthen their market power.
In conclusion, while innovation increases economic efficiency; in some cases it may lead to expanding of monopoly power. Moreover, innovation may destroy monopoly power, but this process is neither automatic nor inevitable. However, technological change, innovation and efficiency doesn’t always bring monopoly power.
