A common approach to defining equivalence scales is to consider a household modelled as if it maximizes a single utility function. This may be founded on an assumption of the household maximizing a welfare function of individual utilities. For a positive analysis of the household, this may be...

Amartya Sen has developed the so-called capability approach to meet the criticism that income alone may be insufficient as a measure of economic inequality. This is because knowledge about people's income does not tell us what they are able to acquire with that income. For example, people with...

A review of the theoretical literature on optimal indirect taxation reveals that analytical arguments in favor of uniform indirect taxation seem weak and rather unrealistic; hence determining the optimal tax structure remains an empirical issue. However, reviewing the empirical contributions...

There is no consensus on how to measure interpersonally comparable, cardinal utility. Despite of this, people repeatedly make welfare evaluations in their everyday lives. However, people do not always agree on such evaluations, and this is one important reason for political disagreements. Thus,...

This paper concerns optimal emissions of greenhouse gases when catastrophic consequences are possible. A numerical model is presented which takes into account both continuous climate-feedback damages as well as the possibility of a catastrophic outcome. The uncertainty in the model concerns...

The partial revenue from each indirect tax and the total revenue from all indirect taxes on consumer goods are derived as functions of all commodity prices, the tax rates of each commodity, total expenditure and demographic variables using a complete demand system. Within this framework we...

Income-based as well as most existing multidimensional poverty indices (MPI) assume equal distribution within the household and thus are likely to lead to yield a biased assessment of individual poverty, and poverty by age or gender. In this paper we first show that the direction of the bias...

In this paper, we propose to use the so-called Sen-Shorrocks poverty index (Shorrocks, 1995) to measure multidimensional deprivation when only dichotomous variables are available to assess deprivation in the various deprivation domains, the most common case in the literature, and introduce a...

The 2007/2008 food price crisis and the following global economic recession has (temporarily) increased the number of people to suffer from hunger. While the impacts can be measured with precision only ex post, for policy makers it is critical to get a sense of likely impacts ex ante in order to...
