The goal of scientific work is to understand more and more by less and less. In this effort, theoretical unification plays a large part. There are two main types of theoretical unification - unification of different theories of the same field of phenomena and unification of theories of different...

This paper examines the relationship between measures of income poverty, undernourishment, childhood undernutrition, and child mortality in developing countries. While there is, as expected, a close aggregate correlation between these measures of deprivation, the measures generate some...

The "Retired Husband Syndrome", that affects the mental health of wives of retired men around the world, has been anecdotally documented but never formally investigated. We use Japanese micro data and the exogenous variation generated by the 2006 revision of the Japanese Elderly Employment...

We use British panel data to determine the exogenous impact of income on a number of individual health outcomes: general health status, mental health, physical health problems, and health behaviors (drinking and smoking). Lottery winnings allow us to make causal statements regarding the effect...

Demand for air quality depends on health impacts and defensive investments that improve health, but little research assesses the empirical importance of defenses. We study an important cap-and-trade market, which dramatically reduced NOx emissions, a key ingredient in ozone formation. A rich...

This paper examines the determinants of the health of children ages 6 to 19, as reported in the Child Development Supplements (CDS) to the Panel Study of Income Dynamics (PSID). The primary focus is on the effect of religion on the reported overall health and psychological health of the child....

This paper investigates the high correlation in infant mortality across siblings using micro-data for each of the fifteen major states of India. The main finding is that, in thirteen of the fifteen states, there is evidence of a causal effect of a child death on the risk of death of the...

While much is now known about the effects of physical health shocks to pregnant women on the outcomes of the in-utero child, we know little about the effects of psychological stresses. One clear form of stress to the mother comes from the death of a parent. We examine the effects of the death of...

Using a unique dataset we study both the actual and self-perceived relationship between subjective well-being and income comparisons against a wide range of potential comparison groups, enabling us to investigate a broader range of questions than in previous studies. In questions inserted into a...

Understanding the exact connection between inequality and justice is important because justice is classically regarded as the first line of defense against self-interest and inequality. Absent a strong and clear link between inequality and justice, the sense of justice would not awaken to exert...
