In other words, returns to scale analysis is a long-term theory because a company can only change the scale of production in the long run by changing factors of production, such as building new facilities, investing in new machinery, or improving technology.
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.
Returns to scale can be Increasing returns to scale: doubling all input usages more than doubles output. Decreasing returns to scale: doubling all input usages less than doubles output. Constant returns to scale: doubling all input usages exactly doubles output.
The presence of increasing returns means that a one percent increase in the usage levels of all inputs would result in a greater than one percent increase in output; the presence of decreasing returns means that it would result in a less than one percent increase in output. Constant returns to scale is the in-between case.
The shape of the long-run marginal and average costs curves is influenced by the type of returns to scale. The long-run is a planning and implementation stage. [6] [7] Here a firm may decide that it needs to produce on a larger scale by building a new plant or adding a production line. The firm may decide that new technology should be ...
From January 2008 to December 2012, if you bought shares in companies when Brenda J. Gaines joined the board, and sold them when she left, you would have a -98.7 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The engine for growth can be as simple as a constant return to scale production function (the AK model) or more complicated set ups with spillover effects (spillovers are positive externalities, benefits that are attributed to costs from other firms), increasing numbers of goods, increasing qualities, etc. [citation needed]
