Becoming poor and the cutback in the demand for health services in Israel.

Background: This paper examines whether individuals facing the threat of poverty are curtailing their consumption of various goods and services in a given order and, if among the expenditures that are cut back, there are also health expenditures. The location of individuals in this order of cutback is then used to derive the degree of their deprivation and the factors that affect the extent of this deprivation.

Methods: This order of curtailment of expenditures is obtained on the basis of an algorithm originally devised to derive the order of acquisition of durable goods.

On social polarization and ordinal variables: the case of self-assessed health.

Social polarization refers to the measurement of the distance between different social groups, defined on the basis of variables such as race, religion, or ethnicity. We propose two approaches to measuring social polarization in the case where the distance between groups is based on an ordinal variable, such as self-assessed health status. The first one, the 'stratification approach', amounts to assessing the degree of non-overlapping of the distributions of the ordinal variable between the different population subgroups that are distinguished.

On the cardinal measurement of health inequality when only ordinal information is available on individual health status.

This paper suggests new indices of health inequality which may be used when only ordinal information is available on individual health status. We borrow ideas from the literature on the measurement of occupational or residential segregation and show that indices of ordinal segregation which have been recently proposed may be also applied to the measurement of health inequality. We also prove that these indices satisfy four axioms introduced to measure inequality with ordered response health data so that the new indices presented in this paper are consistent with the inequality ordering proposed by Allison and Foster.
