THE SENSITIVITY OF INCOME INEQUALITY TO CHOICE OF EQUIVALENCE SCALES

To account for the fact that a household's needs depend on its size and composition most studies on income inequality adjust the observed household incomes by equivalence scales. However, since the rationale for choosing a specific scale is rather vague the importance of testing the sensitivity of income inequality estimates to choice of equivalence scales has long been acknowledged. The sensitivity studies in the literature are restricted to equivalence scales that do not depend on the income level of the reference household which means that the effect of a rise in the household size on the scale rate does not depend on whether the household is poor or rich. By using Norwegian micro-data it is shown that the introduction of an income-dependent scale produces results that are in conflict with the widespread view of robustness of results to choice of equivalence scales.     

Internet Tool Use and Virtual Co-Creation in the Brazilian Construction Industry: Organizational Practices and Consumers' Personal Values

ABSTRACT

This article analyzes the use of Internet tools and virtual co-creation initiatives of firms ranked among the top 100 in the Brazilian building industry. The research was based on observation of the companies' websites and of 200 posts written by participants in a collaborative building project. Websites were observed for the way online interaction tools were aligned to their declared goals. Posts were analyzed using discourse analysis and coded on the basis of the list of values. Results show that only three companies use online tools for the purpose of co-creation and that customer enjoyment is the primary driver of co-creation.
