The congruence between two configurations of points quantifies their similarity. The configurations to be compared are, in general, produced by factor analytic methods which decompose an “observations by variables” data matrix and produce one set of factor scores for the observations and one set of factor scores (i.e., the “loadings”) for the variables. The congruence between two sets of factor...

This paper investigates the robustness of recent findings on the effect of parental education and income on child health. We are particularly concerned about spurious correlation arising from the potential endogeneity of parental income and education. We adopt an instrumental variables approach and our results suggest that the parental income and education effects are generally larger than are ...

We apply an extension of the Rothbarth approach to estimate the share of household resources accruing to children (i.e., the cost of children) in Ireland. The method also allows us to identify the economies of scale in the household and indifference scales in Lewbel (2003)’s sense. A practical aspect of the present approach is that it does not require price variation. The identification of the ...

We develop a new model of “featureful” city in which locations are differentiated by two attributes, that is, the distance to employment centers and accessibility given amenities. The residential equilibrium involves spatial separation households sharing similar incomes. Under Stone-Geary preferences, amenities commuting subsumed into location-quality index. Hence, assignment becomes one-dimens...

Ordinal trees are arbitrary rooted trees where the children of each node are ordered. We consider succinct, or highly space-efficient, representations of (static) ordinal trees with n nodes that use 2n+ o(n) bits of space to represent ordinal trees. There are a number of such representations: each supports a different set of tree operations in O(1) time on the RAM model. In this paper we focus ...
