The analysis reported in Chapters 2 through 6, and outlined earlier, has
several innovative features:
- • The first, in Chapter 2, is the concept of “equally distributed happiness”.4 The idea here is that social welfare is reduced if happiness is unequally distributed and that, therefore, one might be willing to accept a lower level of overall happiness providing it was equally distributed. How much lower would depend on the extent to which one was averse to inequality in the distribution of happiness, and Chapter 2 presents estimates of “equally distributed happiness” with respect to different levels of inequality aversion.
- • The second, in Chapter 3, is to use an econometric model with interaction effects which allows men and women to respond differently to each of several depression/anxiety/anger-inducing factors. This allows one to test whether there is a significant gender difference in responses to these conditions.
- • The third, also in Chapter 3, is to use a decomposition methodology to quantify the contribution of differences in exposure and differences in response (to condition-inducing factors) to inter-gender differences in depression, anxiety, and anger rates.
- • The fourth, in Chapter 4, is to use a joint model to estimate the likelihood of emotional and physical abuse of married women in order to allow for the fact that the two probabilities are likely to be correlated.
- • The fifth, also in Chapter 4, is to use inequality decomposition to measure the individual contributions of household wealth, alcohol, and controls to the likelihood of wives being subject to violence from their husbands.
- • The sixth, in Chapter 5, is to suggest and implement a methodology for measuring the extent to which the stop rate of an ethnic group is the result of racial bias by the police and the extent to which it is due to location (i.e., living in areas where there are a large number of police stops).
- • The seventh, also in Chapter 5, is to use a Bayesian methodology to show how any post-stop arrests could be aligned with the initial stops to examine whether groups that are disproportionately stopped are also disproportionately more likely to offer a reason for arrest.
- • The eighth, in Chapter 6, is the use of techniques borrowed from analysis of poverty to develop the concept of a “xenophobia score” which is used to measure the amount of xenophobia in different regions of the world.
- • The ninth, also in Chapter 6, is the decomposition of homophobia into two parts: as exercised by those who regard homosexuality as wrong (intolerance) and as exercised by those who do not think homosexuality as wrong but who are, nevertheless, anxious to conform to societal norms (conformity). The outcome with respect to overall homophobia is then a weighted average of intolerance and conformity.
- • The tenth, also in Chapter 6, is to define the concept of gender tension in terms of a disjoint between male and female attitudes towards gender equality and to provide measures of such tension for the world’s regions and its major religions.
- • Finally, and most important, threaded through the chapters is a prediction technique which forms the foundation for many of the reported results. This is the method of recycled predictions.5 In evaluating the effect of two characteristics A and В on the likelihood of a particular outcome, the method of recycled predictions compares two sets of average probabilities: first, under an “all have the characteristic A” scenario and, then, under an “all have the characteristic B” scenario, with the values of the other variables remaining unchanged between the scenarios. The difference in the two probabilities is then entirely due to the attributes represented by A and В (e.g., caste/racial differences in Chapter 2 or gender differences in Chapter 3). These probabilities are referred to as the predicted probabilities of an event under A and B.
The book covers a diversity of issues using the technical apparatus of economics to rigorously interrogate the relevant data. It has been written so that every chapter is self-contained and can be read independently of the others. Since some of the techniques are used in more than one chapter their explanation is repeated in the chapters in order to maintain this feature of self-containment.

- 2 Using World Values Survey (WVS) data, Dowling and Yap examine the strength of factors determining both happiness and life satisfaction for respondents in three regions: Asia, Africa and Fatin America. In so doing, they first consider all respondents to the WVS in their entirety and, second, those respondents to the WVS who could be considered “poor” either in terms of income, education, or health.
