Economic Efficiency
Economic Efficiency the ratio between the results of production—output and material services—on the one hand and expenditures of labor and the means of production on the other. Under socialism, economic efficiency is a key index of economic development. For the capitalist entrepreneur, expenditures take the form of fixed capital stock and circulating productive capital advanced by him, and results take the form of profits. Comparisons of expenditures and results based on report and statistical data for the various branches of the economy and for the national economy as a whole are used in the management of capitalist firms, whose primary motive is the desire to maximize profits. economic efficiency
Market EfficiencyThe extent to which the price of an asset reflects all information available. Economists disagree on how efficient markets are. Followers of the efficient markets theory hold that the market efficiently deals with all information on a given security and reflects it in the price immediately, and that technical analysis, fundamental analysis, and/or any speculative investing based on those methods are useless. On the other hand, the primary observation of behavioral economics holds that investors (and people in general) make decisions on imprecise impressions and beliefs, rather than rational analysis, rendering markets somewhat inefficient to the extent that they are affected by people.economic efficiency an aspect of PRODUCTION that seeks to identify, for a given level of OUTPUT, the combination of FACTOR INPUTS that minimizes the COST of producing that output. More broadly, economic efficiency is equated with the effectiveness of RESOURCE ALLOCATION in the economy as a whole such that outputs of goods and services fully reflect consumer preferences for these goods and services as well as individual goods and services being produced at minimum cost through appropriate mixes of factor inputs.
