Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain demand in economics, relay the theory of demand curves, elasticity and shifts from economics references, describe kinds such as effective, derived and labour demand, and distinguish economic demand from wants and from legal demands.

In economics, the quantity of a good or service that buyers are willing and able to purchase at various prices over a period, represented by a demand curve and shifted by income, preferences, prices of related goods and expectations, with forms such as effective demand backed by purchasing power, derived demand for inputs arising from demand for outputs, labour demand from employers, and sectoral demands such as energy and fossil fuel demand or educational demand; demand interacts with supply to determine prices and quantities in markets.

What it is for: Not applicable; an economic concept.

It can be explain the concept and curve; relay elasticity and shifts; describe kinds of demand; distinguish from wants and legal demands.

Distinguishing features

Price-quantity relation

Elasticity

Shift factors

Aggregate and sectoral forms

What it looks like

Not a visible object; a downward-sloping curve on a price-quantity diagram.

Physical character

law of demand: quantity falls as price rises principle - with exceptions

price elasticity: percentage change in quantity over percentage change in price formula

How it is recognised

Willingness and ability to buy at prices

Effective, derived, labour, energy, fossil fuel and educational demand

A want lacks purchasing power; a legal demand is a claim; supply is the other side of the market

What the second pass must settle

  • Should aggregate demand and labour demand be separate primary entries?
  • How should economics references be linked?
  • The registry entry has merged aliases naming sectoral demands; should they be split off?
