The advent of new biotechnologies implies significant changes in the world, both biologically and industrially. Biologically, these new technologies represent changes on a scale never before witnessed in the context of evolutionary systems. How these systems will respond to these changes is uncertain and potentially very significant. The first part of this volume addresses these issues in a series of chapters considering the manner in which societies might analyse and manage these systemic responses to biotechnological changes.

The second part of the volume addresses the industrial...

The marginal price elasticities estimated by Martinez-Espineira conforms to expectation. The price specification that accounts for the changing proportion of water users in each block yields a higher elasticity (-0. 47) compared to the spec ification ignoring this feature of the data. However, this difference is not found to be statistically significant, a result attributed to the low power of the test (small sample size limiting the accuracy of estimates). In conclusion, the paper provides a theoretically correct price specification for demand functions under block pricing and aggregate...
