Instrument constitutes a device that is both technical and social, that organizes
specific social relations between the state and those it is addressed to, according
to the representations and meanings it carries. It is a particular type of institution, a technical device with the generic purpose of carrying a concrete concept
of the politics/society relationship and sustained by a concept of regulation
It is possible to differentiate between levels of observation by distinguishing between “instrument,” “technique,” and “tool”: for the sake of
clarity we suggest to understand
1. The instrument as a type of social institution (census taking, map
making, statutory regulation, taxation).
2. The technique as a concrete device that operationalizes the instrument (statistical nomenclature, a type of graphic representation, a
type of law or decree).
3. The tool as a micro device within a technique (statistical category,
the scale of definition of a map, the type of obligation provided for
by a legal text, presence/absence of sanction).

There are a range of types of market based instruments including trading schemes, offset schemes, subsidies and
