Implementation issues<br />

A further comparison that can be made is between the scheme as it was<br />

implemented and what might be termed an ‘optimal’ public-policy intervention.<br />

In section 7 we identified a number of issues that arise in the implementation of<br />

specific market-based mechanisms. These issues have been suggested by the<br />

academic literature on the use of market-based mechanisms and previous<br />

experience of their use. In the case studies we consider the implementation<br />

issues associated with specific market-based mechanisms. These issues are<br />

specific to the mechanism under consideration (although there may be some<br />

overlap between different mechanisms). In Part II we made general<br />

recommendations on how policy makers might best deal with these issues and<br />

implement the chosen market mechanism in practice.<br />

Summary<br />

Section 8 – Framework <strong>for</strong> assessing market mechanisms<br />

The case studies in Part IV are designed to provide practical illustrations of the<br />

theory developed in this literature review. They have been selected to cover a<br />

range of different mechanisms used in different economic and policy contexts.<br />

Each study looks at the policy goal the market mechanism was designed to<br />

deliver and the problems with previous methods of intervention that motivated<br />

the introduction of market <strong>for</strong>ces. We describe the way in which each<br />

mechanism was introduced and, with reference to theoretical predictions, we<br />

look at the extent to which scheme design has been successful in capturing<br />

potential benefits and avoiding potential problems. We also consider<br />

implementation issues and conclude in each case by drawing lessons that could<br />

be helpful <strong>for</strong> policy makers considering the use of this particular mechanism.<br />
