    Ecological efficiency is a combination of several related efficiencies that describe resource utilization and the extent to which resources are converted into biomass. [1] ...

    en.wikipedia.org/wiki/Economic_efficiency

    Microeconomic reform is the implementation of policies that aim to reduce economic distortions via deregulation, and move toward economic efficiency. However, there is no clear theoretical basis for the belief that removing a market distortion will always increase economic efficiency.

    In 2015, therefore, approximately 4.55 kg of farmed fish was produced for every 1 kg of wild fish harvested and used in feed. (For Salmon & Trout, the FIFO ratios for 2000, 2010, and 2015 are: 2.57, 1.38, 0.82.) [30] As of 2015 farm-raised Atlantic salmon had a commodified feed supply with four main suppliers, and an FCR of around 1. [31]

  5. Productive efficiency - Wikipedia

    en.wikipedia.org/wiki/Productive_efficiency

    In microeconomic theory, productive efficiency (or production efficiency) is a situation in which the economy or an economic system (e.g., bank, hospital, industry, country) operating within the constraints of current industrial technology cannot increase production of one good without sacrificing production of another good.

  6. Productivity (ecology) - Wikipedia

    Primary production in most ecosystems is dominated by the process of photosynthesis, In which organisms synthesize organic molecules from sunlight, H 2 O, and CO 2. [3] Aquatic primary productivity refers to the production of organic matter, such as phytoplankton, aquatic plants, and algae, in aquatic ecosystems, which include oceans, lakes ...

  7. Eco-efficiency - Wikipedia

    First, incremental eco-efficiency, which "specifies the effects of the total value of a product system or sector and its total concomitant environmental effects." [1] Second, an analysis method nicknamed win-win, which "gives a comparison between a historical reference situation and potentially new situations based on the use of new technologies."

  8. Productivity - Wikipedia

    en.wikipedia.org/wiki/Productivity

    Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. [1]

  9. Production (economics) - Wikipedia

    en.wikipedia.org/wiki/Production_(economics)

    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.
