Sequencing and the Adding-up Property in Contingent Valuation of Endangered Species: Are Contingent Non-Use Values Economic Values?

This paper presents tests of the theoretical validity of the contingent valuation (CV) method. The validity of CV is especially a concern when involving environmental goods with a predominant non-use value. One test of theoretical validity is the adding-up property that implies that a specific good should be equally valued irrespectively of it is being valued directly or built-up sequentially. In this CV study four independent sub-samples stated willingness to pay for the same composite good, or package, using different sequences. One sub-sample valued the composite good directly, while two sub-samples faced built-up sequences valuing first subsets of this composite good. A fourth sub-sample valued the composite good from a dividing-out approach, facing first the valuation of a larger multi-package. Theoretically expected sequencing effects were observed; the subset goods obtained higher values earlier in a sequence, and the dividing-out approach decreased the stated value for the composite good. Most importantly, these CV data did pass the tests of the adding-up property.     

Response to the Comment: “What is Heterodox Economics? Conversations with Historians of Economic Thought”

The comment to “What is Heterodox Economics? Conversations with Historians of Economic Thought” spotlights critical issues in the possibility and probability of articulation and proposes a compelling argument in the explanation of the “inability of heterodoxy to define itself...” The core argument suggests that heterodox groups of economic thought cannot successfully articulate the nature of its varied programs until it recognizes and articulates the metaphysically and ontologically different system of knowledge which serves as the foundation for heterodox thought.     

Do Selection Criteria Make a Difference?: Visa Category and the Labour Market Status of Immigrants to Australia

This paper assesses the role of selection criteria in the immigrant settlement process. Do skill-based immigrants have higher participation and employment rates than family-based immigrants? Does this represent a head start or a persistent labour market advantage? The Longitudinal Survey of Immigrants to Australia is used to address these questions. Generally, migrants selected for their skills have better labour market outcomes. Over time, the relative gap in participation rates increases, while the gap in employment rates decreases. Net of visa category, outcomes are better for native English speakers and for those who visited Australia prior to migration.
