The standard logistic function is the logistic function with parameters =, =, =, which yields = + = + = / / + /.In practice, due to the nature of the exponential function, it is often sufficient to compute the standard logistic function for over a small range of real numbers, such as a range contained in [−6, +6], as it quickly converges very close to its saturation values of 0 and 1.
According to Kaldor, “The purpose of a theory of economic growth is to show the nature of non-economic variables which ultimately determine the rate at which the general level of production of the economy is growing, and thereby contribute to an understanding of the question of why some societies grow so much faster than others.” [2] [1]
Another example relates to the household's social status in the local community of residence. Perceptions of the obligations that come with higher social status may well influence spending patterns; for example, one may feel the need to show off with a TV or have enough food ready if someone shows up.
There are appreciable variations (2 to 5 percent) in the rate of growth of labor productivity and of total output among countries. Kaldor did not claim that any of these quantities would be constant at all times; on the contrary, growth rates and income shares fluctuate strongly over the business cycle. Instead, his claim was that these ...
In economics and microeconomics, the economic region of production is an offshoot of the theory of production function with two variables. It is a cost-oriented theory which defines the region in which the optimal factor combination will lie. [1] It serves as a map of the region of optimal production.
The AK model of economic growth is an endogenous growth model used in the theory of economic growth, a subfield of modern macroeconomics.In the 1980s it became progressively clearer that the standard neoclassical exogenous growth models were theoretically unsatisfactory as tools to explore long run growth, as these models predicted economies without technological change and thus they would ...
For example, assume that the growth of labor productivity is the same as that in the trend and that current productivity equals its trend value: gZ = gZ T and Z = Z T . The markup reflects both the firm's degree of market power and the extent to which overhead costs have to be paid.
