In a 2005 paper Kanezawa proposed a generalisation of the classic Trivers-Willard hypothesis. It was argued that as a result taller and heavier parents should have more sons relative to daughters. Using two British cohort studies, evidence was presented which was partly consistent with the...

Numerous papers have documented a positive association between height and good physical health and also with good economic outcomes such as earnings. A smaller number have argued for an association with well-being. In this paper, cross-country data from Europe is used to analyse whether...

Kanazawa (2007) offers an explanation for the variation across countries of average intelligence. It is based on the idea human intelligence is a domain specific adaptation and that both temperature and the distance from some putative point of origin are proxies for the degree of novelty that...

I show a simple back-of-the-envelope method for calculating marginal effects in binary choice and count data models. The approach suggested here focuses attention on marginal effects at different points in the distribution of the dependent variable rather than representative points in the joint...

University tuition fees for undergraduates were abolished in Ireland in 1996. This paper examines the effect of this reform on the socioeconomic gradient (SES) to determine whether the reform was successful in achieving its objective of promoting educational equality. It finds that the reform...

This paper uses a cross-country representative sample of Europeans over the age of 50 to analyse whether individuals' height is associated with higher or lower levels of well-being. Two outcomes are used: a measure of depression symptoms reported by individuals and a categorical measure of life...

This paper addresses the question of whether higher levels of education contribute to greater tolerance of homosexuals. Using survey data for Ireland and exploiting a major reform to education, the abolition of fees for secondary schools in 1968, it is shown that increases in education causes...

This paper uses a new large population survey from twelve European countries to measure the association between handedness and depression. It is found that that depressive symptoms are significantly higher amongst left-handed men. While 19% of right handed men report experiencing depressive...
