This paper considers the use of alternative welfare metrics in evaluations of income inequality in a multi-period context. Using Norwegian longitudinal income data, it is found, as in many studies, that inequality is lower when each individual’s annual average income is used as welfare metric,...

This paper examines the sensitivity of inequality and poverty measures to the adult equivalence scale and the unit of analysis. Comparisons are made using parametric equivalence scales, and income units include individuals, equivalent adults and households. The role of the correlation between...

The distance metric on the location space for multidimensional public good varieties represents complementarity between the goods features. "Euclidean" feature complementarity has atypical strong properties that lead to a failure of intuition about the optimal-menu design problem. If the...

Extensive research has shown that few robust results regarding the optimal tax structure are available. Moreover, the stylised models used in optimal tax analyses are not appropriate for practical policy advice. This paper proposes a method of examining optimal marginal income tax reforms using...

This research takes the analysis of the relationship between energy and income in a different direction than prior research, and it introduces a new set of analytical tools to the area. The results of our research are important because they raise additional questions about the effectiveness of...

This paper describes a method of estimating the welfare effects of a set of price changes, using money measures of welfare change such as compensating and equivalent variations, and the associated concept of "equivalent income".

The good health of an individual is a combination of uncontrollable factors that includes genetics and random events and controllable factors through the regulation of activities such as smoking, drinking, eating, exercise and other informed choices. Since the work of Grossman (1972) a...

This paper examines the role played in the labour market by norms of need and focuses, in particular, on the relationship between social norms and the regulation of minimum wge rates. It develops a theoretical model to describe the possible nature of this relationship and utilises the results of...
