Fertility rates must level off to the replacement rate (the net reproduction rate should be 1). If the fertility rate remains higher than the replacement rate, the population would continue to grow. 2. Mortality rate must stop declining, that is, it must remain constant. 3. Lastly, the age structure must adjust to the new rates of fertility and ...
A loosely defined goal of ZPG is to match the replacement fertility rate, which is the average number of children per woman which would hold the population constant. This replacement fertility will depend on mortality rates and the sex ratio at birth, and varies from around 2.1 in developed countries to over 3.0 in some developing countries. [21]
In demography, replacement migration is a theory of migration needed for a region to achieve a particular objective (demographic, economic or social). [1] Generally, studies using this concept have as an objective to avoid the decline of total population and the decline of the working-age population.
In 20th-century discussions of Karl Marx's economics, the transformation problem is the problem of finding a general rule by which to transform the "values" of commodities (based on their socially necessary labour content, according to his labour theory of value) into the "competitive prices" of the marketplace.
The exchange rate disconnect puzzle: The exchange rate disconnect puzzle, also one of the so-called real exchange rate puzzles, concerns the weak short-term feedback link between exchange rates and the rest of the economy. In most economies, the exchange rate is the most important relative price, so it is surprising, and thus far unexplained ...
The concept of maximum sustainable yield is not always easy to apply in practice. Estimation problems arise due to poor assumptions in some models and lack of reliability of the data. [8] [24] Biologists, for example, do not always have enough data to make a clear determination of the population's size and growth rate. Calculating the point at ...
Under the standard assumption of neoclassical economics that goods and services are continuously divisible, the marginal rates of substitution will be the same regardless of the direction of exchange, and will correspond to the slope of an indifference curve (more precisely, to the slope multiplied by −1) passing through the consumption bundle in question, at that point: mathematically, it ...
The insider-outsider theory is a theory of labor economics that explains how firm behavior, national welfare, and wage negotiations are affected by a group in a more privileged position. [1] The theory was developed by Assar Lindbeck and Dennis Snower in a series of publications beginning in 1984. [1] [2] [3] Wages set by insiders [4]
