Income, Income Inequality and the “Hidden Epidemic” of Traffic Fatalities

Few, if any, epidemics responsible for 20 million severe injuries and/or deaths each year, globally, receive less public attention than do traffic accidents truly making them a “hidden epidemic”. Worse yet, the epidemic is growing as evidenced by World Health Organization data which show deaths from traffic accidents increasing by 20 percent between 1990 and 2002. In this paper we examine how a country’s stage of development and its distribution of income affect its traffic fatality rate. In our theoretical analysis, we show that traffic fatalities should have a nonlinear relationship with a country’s level of per capita income while being a decreasing function of income equality. We test our model’s predictions by evaluating data from 79 countries between 1970 and 2000, taking into account other factors that influence traffic fatalities like the motorization rate, health care networks, education, and alcohol consumption and find strong evidence of the theoretical model’s predictions. Specifically, the empirical results indicate that traffic fatalities are negatively related to income equality throughout its range and also are negatively related to per capita income, above a threshold of about $11,500.Vulnerable road users, traffic safety interventions, per capita income, income inequality

From Cholera Outbreaks to Pandemics: The Role of Poverty and Inequality

Cholera and other diarrheal diseases are the second leading cause of death among the poor globally. The tragedy of this statistic is that it need not be the case. Unlike many afflictions, the impact of cholera can be greatly reduced, if not eliminated, through the collective action of clean water services. This begs the question of why such collective action is absent in much of the world. To address this, we first develop a theoretical model which indicates that the required collective action is an increasing function of both a country’s level of income and income equality. We test these predictions by analyzing 1,032 annual observations arising from 17 relatively poor countries between the years 1980 and 2002. The countries come from the Americas, Africa, and Asia. In the first part of the analysis, we find that the collective action of providing clean water is, as predicted, an increasing function of income and equality. Following this, we find that both the numbers of cases and deaths resulting from a given cholera outbreak are strongly and negatively related to the collective action.Cholera, diarrheal diseases, pandemics, per capita income, inequality

Earthquake fatalities: the interaction of nature and political economy

In our theoretical model, we show that as per capita income decreases and the level of inequality increases, different segments of society are less likely to agree on the distribution of the burden of the necessary collective action, causing the relatively-wealthy simply to self-insure against the disaster while leaving the relatively-poor to its mercy. We then evaluate 269 large earthquakes occurring worldwide (1960-2002), taking into account other factors such as an earthquake's magnitude, depth and proximity to population centers. Using a Negative Binomial estimation strategy with both random and fixed estimators, we find strong evidence of the theoretical model’s predictions.Earthquake, Fatalities, Nature, Political economy
