Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits. [7]
Bottles in different colours Mixed colour glass cullet Public glass waste collection point for different colours of containers. Glass recycling is the processing of waste glass into usable products. [1] Glass that is crushed or imploded and ready to be remelted is called cullet. [2] There are two types of cullet: internal and external.
The Solow growth model is a model of economic development into which the Solow residual can be added exogenously to allow predictions of GDP growth at differing levels of productivity growth. The Balassa–Samuelson effect describes the effect of variable Solow residuals: it assumes that mass-produced traded goods have a higher residual than ...
Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...
These tendencies could in theory lead to longer-term economic benefits (which may cause GDP growth). [8] [11] There is some evidence that geological disasters do more economic harm than climate-related disasters, in the long term. Geological disasters, such as landslides and earthquakes, happen with little immediate warning and kill many people ...
Note that since utility is not observable, the substitution effect is not directly observable. Still, it can be calculated by referencing the other two observable terms in the Slutsky equation. This process is sometimes known as the Hicks decomposition of a demand change. [2] The equation can be rewritten in terms of elasticity:
Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
This definition is also known as the direct elasticity of substitution. The other economist was Joan Robinson, who defined elasticity of substitution as the change in proportion of the ratio of the number of factors used divided by the change in proportion of the ratio of each factor's prices. These two definitions function in the same way when ...
