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]
The accelerator effect in economics is a positive effect on private fixed investment of the growth of the market economy (measured e.g. by a change in gross domestic product (GDP)). Rising GDP (an economic boom or prosperity) implies that businesses in general see rising profits, increased sales and cash flow, and greater use of existing capacity.

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 ...
For normal goods, the Engel curve has a positive gradient. That is, as income increases, the quantity demanded increases. That is, as income increases, the quantity demanded increases. Amongst normal goods, there are two possibilities.
Endogenous growth theory holds that investment in human capital, innovation, and knowledge are significant contributors to economic growth. The theory also focuses on positive externalities and spillover effects of a knowledge-based economy which will lead to economic development. The endogenous growth theory primarily holds that the long run ...
The Lorenz curve is invariant under positive scaling. If X is a random variable, for any positive number c the random variable c X has the same Lorenz curve as X. The Lorenz curve is flipped twice, once about F = 0.5 and once about L = 0.5, by negation. If X is a random variable with Lorenz curve L X (F), then −X has the Lorenz curve:
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.
