Demographic economics or population economics is the application of economic analysis to demography, the study of human populations, including size, growth, density, distribution, and vital statistics.
Demography is the statistical study of populations, especially human beings.
In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. The area of a sexual population is the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas.
In population genetics and population ecology, population size is the number of individual organisms in a population. Population size is directly associated with amount of genetic drift, and is the underlying cause of effects like population bottlenecks and the founder effect. Genetic drift is the major source of decrease of genetic diversity within populations which drives fixation and can potentially lead to speciation events.
Aspects of the subject include
The total fertility rate (TFR), sometimes also called the fertility rate, absolute/potential natality, period total fertility rate (PTFR), or total period fertility rate (TPFR) of a population is the average number of children that would be born to a woman over her lifetime if:
Family economics applies economic concepts such as production, division of labor, distribution, and decision making to the study of the family. It tries to explain outcomes unique to family—such as marriage, the decision to have children, fertility, polygamy, time devoted to domestic production, and dowry payments using economic analysis.
Life expectancy, often abbreviated to LEB, is a statistical measure of the average time an organism is expected to live, based on the year of its birth, its current age and other demographic factors including gender. The most commonly used measure of life expectancy is at birth, which can be defined in two ways. Cohort LEB is the mean length of life of an actual birth cohort and can be computed only for cohorts born many decades ago, so that all their members have died. Period LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year.
Other subfields include measuring value of lifeand the economics of the elderly and the handicapped and of gender, race, minorities, and non-labor discrimination. In coverage and subfields, it complements labor economics and implicates a variety of other economics subjects.
The value of life is an economic value used to quantify the benefit of avoiding a fatality. It is also referred to as the cost of life, value of preventing a fatality (VPF) and implied cost of averting a fatality (ICAF). In social and political sciences, it is the marginal cost of death prevention in a certain class of circumstances. In many studies the value also includes the quality of life, the expected life time remaining, as well as the earning potential of a given person especially for an after the fact payment in a wrongful death claim lawsuit.
The Journal of Economic Literature classification codes are a way of categorizing subjects in economics. There, Demographic Economics is paired with Labor Economics as one of 19 primary classifications at JEL: J.It has 8 subareas, which are listed below with JEL-code links to corresponding available article-preview links of The New Palgrave Dictionary of Economics (2008) Online:
The Journal of Economic Literature is a peer-reviewed academic journal, published by the American Economic Association, that surveys the academic literature in economics. It was established in 1963 as the Journal of Economic Abstracts, and is currently one of the highest ranked journals in economics. As a review journal, it mainly features essays and reviews of recent economic theories. The editor-in-chief is Steven Durlauf.
Labour economics seeks to understand the functioning and dynamics of the markets for wage labour.
Articles in economics journals are usually classified according to the JEL classification codes, a system originated by the Journal of Economic Literature. The JEL is published quarterly by the American Economic Association (AEA) and contains survey articles and information on recently published books and dissertations. The AEA maintains EconLit, a searchable data base of citations for articles, books, reviews, dissertations, and working papers classified by JEL codes for the years from 1969. A recent addition to EconLit is indexing of economics-journal articles from 1886 to 1968 parallel to the print series Index of Economic Articles.
The cost of raising a child varies from country to country.
Generational accounting is a method of measuring the fiscal burdens facing today's and tomorrow's children. Laurence Kotlikoff's individual and co-authored work on the relativity of fiscal language demonstrates that conventional fiscal measures, including the government's deficit, are not well defined from the perspective of economic theory. Instead, their measurement reflects economically arbitrary fiscal labeling conventions. "Economics labeling problem," as Kotlikoff calls it, has led to gross misreadings of the fiscal positions of different countries, starting with the United States, which has a relatively small debt-to-GDP ratio, but is, arguably, in worse fiscal shape than any developed country. Kotlikoff's identification of economics labeling problem, beginning with his 1984 Deficit Delusion article in The Public Interest led him to push for generational accounting, a term he coined and that provides the title for his 1993 book, Generational Accounting.
Income and fertility is the association between monetary gain on one hand, and the tendency to produce offspring on the other. There is generally an inverse correlation between income and the total fertility rate within and between nations. The higher the degree of education and GDP per capita of a human population, subpopulation or social stratum, the fewer children are born in any industrialized country. In a 1974 UN population conference in Bucharest, Karan Singh, a former minister of population in India, illustrated this trend by stating "Development is the best contraceptive."
Demographic dividend, as defined by the United Nations Population Fund (UNFPA) means, "the economic growth potential that can result from shifts in a population’s age structure, mainly when the share of the working-age population is larger than the non-working-age share of the population ". In other words, it is “a boost in economic productivity that occurs when there are growing numbers of people in the workforce relative to the number of dependents.” UNFPA stated that, “A country with both increasing numbers of young people and declining fertility has the potential to reap a demographic dividend.
The phenomenon and theory of the demographic transition refers to the historical shift in demographics from high birth rates and high infant death rates in societies with minimal technology, education and economic development, to demographics of low birth rates and low death rates in societies with advanced technology, education and economic development, as well as the stages between these two scenarios. Although this shift has occurred in many industrialized countries, the theory and model are frequently imprecise when applied to individual countries due to specific social, political and economic factors affecting particular populations.
Economics is the social science that studies the production, distribution, and consumption of goods and services.
Kenneth Joseph Arrow was an American economist, mathematician, writer, and political theorist. He was the joint winner of the Nobel Memorial Prize in Economic Sciences with John Hicks in 1972.
A natural experiment is an empirical study in which individuals are exposed to the experimental and control conditions that are determined by nature or by other factors outside the control of the investigators. The process governing the exposures arguably resembles random assignment. Thus, natural experiments are observational studies and are not controlled in the traditional sense of a randomized experiment. Natural experiments are most useful when there has been a clearly defined exposure involving a well defined subpopulation such that changes in outcomes may be plausibly attributed to the exposure. In this sense, the difference between a natural experiment and a non-experimental observational study is that the former includes a comparison of conditions that pave the way for causal inference, but the latter does not.
In the social sciences, methodological individualism is the principle that subjective individual motivation explains social phenomena, rather than class or group dynamics which are illusory or artificial and therefore cannot truly explain market or social phenomena.
Ernst Louis Étienne Laspeyres was a German economist. He was Professor ordinarius of economics and statistics or State Sciences and cameralistics in Basel, Riga, Dorpat, Karlsruhe, and finally for 26 years in Gießen. Laspeyres was the scion of a Huguenot family of originally Gascon descent which had settled in Berlin in the 17th century, and he emphasised the Occitan pronunciation of his name as a link to his Gascon origins.
In economics, the monetary base in a country is the total amount of bank notes and coins circulating in the economy. This includes:
In mathematical economics, the Arrow–Debreu model suggests that under certain economic assumptions there must be a set of prices such that aggregate supplies will equal aggregate demands for every commodity in the economy.
In macroeconomic theory, liquidity preference is the demand for money, considered as liquidity. The concept was first developed by John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) to explain determination of the interest rate by the supply and demand for money. The demand for money as an asset was theorized to depend on the interest foregone by not holding bonds. Interest rates, he argues, cannot be a reward for saving as such because, if a person hoards his savings in cash, keeping it under his mattress say, he will receive no interest, although he has nevertheless refrained from consuming all his current income. Instead of a reward for saving, interest, in the Keynesian analysis, is a reward for parting with liquidity. According to Keynes, money is the most liquid asset. Liquidity is an attribute to an asset. The more quickly an asset is converted into money the more liquid it is said to be.

Involuntary unemployment occurs when a person is willing to work at the prevailing wage yet is unemployed. Involuntary unemployment is distinguished from voluntary unemployment, where workers choose not to work because their reservation wage is higher than the prevailing wage. In an economy with involuntary unemployment there is a surplus of labor at the current real wage. This occurs when there is some force that prevents the real wage rate from decreasing to the real wage rate that would equilibrate supply and demand. Structural unemployment is also involuntary.
Peter Kenneth Newman was an English economist and historian of economic thought. He helped to edit The New Palgrave: A Dictionary of Economics, to which he contributed several articles.
Public economics is the study of government policy through the lens of economic efficiency and equity. Public economics builds on the theory of welfare economics and is ultimately used as a tool to improve social welfare.
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. By convention, these applied methods are beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, and other computational methods. Proponents of this approach claim that it allows the formulation of theoretical relationships with rigor, generality, and simplicity.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.
Ross Marc Starr is an American economist who specializes in microeconomic theory, monetary economics and mathematical economics. He is a Professor at the University of California, San Diego.
In economics, non-convexity refers to violations of the convexity assumptions of elementary economics. Basic economics textbooks concentrate on consumers with convex preferences and convex budget sets and on producers with convex production sets; for convex models, the predicted economic behavior is well understood. When convexity assumptions are violated, then many of the good properties of competitive markets need not hold: Thus, non-convexity is associated with market failures, where supply and demand differ or where market equilibria can be inefficient. Non-convex economies are studied with nonsmooth analysis, which is a generalization of convex analysis.
Convexity is an important topic in economics. In the Arrow–Debreu model of general economic equilibrium, agents have convex budget sets and convex preferences: At equilibrium prices, the budget hyperplane supports the best attainable indifference curve. The profit function is the convex conjugate of the cost function. Convex analysis is the standard tool for analyzing textbook economics. Non‑convex phenomena in economics have been studied with nonsmooth analysis, which generalizes convex analysis.
