Using these techniques, Malthus' population principle of growth was later transformed into a mathematical model known as the logistic equation: = (), where N is the population size, r is the intrinsic rate of natural increase, and K is the carrying capacity of the population. The formula can be read as follows: the rate of change in the ...
The traditional form of the shift-share analysis was developed by Daniel Creamer in the early 1940s, and was later formalized by Edgar S. Dunn in 1960. [2] Also known as the comparative static model, it examines changes in the economic variable between two years. Changes are calculated for each industry in the analysis, both regionally and ...
The economic history of Brazil covers various economic events and traces the changes in the Brazilian economy over the course of the history of Brazil. Portugal , which first colonized the area in the 16th century, enforced a colonial pact with Brazil, an imperial mercantile policy, which drove development for the subsequent three centuries. [ 1 ]
In the post-war period (1945–1960) examples include West Germany, France and Japan, which were able to quickly regain their prewar status by replacing capital that was lost during World War II. Some economists criticise the theory, stating that endogenous factors, such as government policy, are much more influential in economic growth than ...
P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4] t = time. The model can also be written in the form of a differential equation:
The Rostovian take-off model (also called "Rostow's Stages of Growth") is one of the major historical models of economic growth. It was developed by W. W. Rostow. The model postulates that economic modernization occurs in five basic stages, of varying length. [1] Traditional society; Preconditions for take-off; Take-off; Drive to maturity
One of the most basic and milestone models of population growth was the logistic model of population growth formulated by Pierre François Verhulst in 1838. The logistic model takes the shape of a sigmoid curve and describes the growth of a population as exponential, followed by a decrease in growth, and bound by a carrying capacity due to ...
The growth accounting model is normally expressed in the form of the exponential growth function. As an abstract example consider an economy whose total output (GDP) grows at 3% per year. Over the same period its capital stock grows at 6% per year and its labor force by 1%.
