The supply of labor is the relationship between the quantity of labor supplied and the real, or inflation-adjusted, wage rate when all other influences on worker's plans to work are held constant.
A basic economic notion called supply refers to the total amount of a particular commodity or service that is made available to consumers. When shown as a graph, supply can refer to the quantity that is offered at a particular price or the quantity that is offered over a range of prices.
In terms of economics, supply refers to the quantity of items that a person or firm offers to the market, which is equivalent to the total amount that they produce at one particular time. For instance, if Apple produces 100 iPhones, then this is the quantity that is sold.
The following are included in a supply of goods: the agreement-based transfer of property rights over things. the commission-based sale of tangible things by an auctioneer or agent acting under his or her own name but following another person's instructions. delivery of items under a hire-purchase agreement.

To date erosion scientists have failed to address — or have addressed inadequately — some of the ‘big questions’ of our discipline. For example, where is erosion occurring? Why is it happening, and who is to blame? How serious is it? Who does it affect? What should be the response? Can we prevent it? What are the costs of erosion? Our inability or reluctance to answer such questions damages our credibility and is based on weaknesses in commonly-used approaches and the spatial and temporal scales at which much research is carried out. We have difficulty in the recognition, description and quantification of erosion, and limited information on the magnitude and frequency of events that cause erosion. In particular there has been a neglect of extreme events which are known to contribute substantially to total erosion. The inadequacy and frequent misuse of existing data leaves us open to the charge of exaggeration of the erosion problem (a la Lomborg).
Models need to be developed for many purposes and at many scales. Existing models have proved to be of limited value, in the real as opposed to the academic world, both because of problems with the reliability of their results, and difficulties (with associated costs) of acquiring suitable data. However, there are some positive signs: models are now being developed for purposes including addressing questions of off-site impacts and land-use policy. Cheap, reliable and technically simple methods of erosion assessment at the field scale are needed. At the global scale, an up-date of GLASOD based on a scientific approach is urgent so that we are at least able to identify erosion ‘hotspots’.
In terms of explanation of erosion, the greatest need is for a full recognition of the importance of socio-economic drivers. The accession of new countries to the EU with different economic and land-use histories emphasises this need. Too often we have left people, especially the farmers, out of the picture. Our approach could be characterised as ‘data-rich and people-poor’.
