Despite some improvements in recent years, poverty and food insecurity remain widespread and the main challenges in Ethiopia. Using individual and household level data collected in rural Ethiopia, we examine if aspirations are strongly associated with well-being outcomes, as posited in the...

We relate to others in two important ways: we care about others, and we care about how we fare in comparison to others. In some contexts, these two forms of relatedness interact. Caring about others can conveniently be labeled altruism. Caring about how we fare in comparison with others who fare...

Many real-world mechanisms are “noisy” or “fuzzy”, that is the institutions in place to implement them operate with non-negligible degrees of imprecision and error. This observation raises the more general question of whether mechanisms that work in theory are also robust to more...

Is the willingness to make trades influenced by how the total gains from trade are split between the trading partners? We present results from a bilateral trade game (n = 128) where all participants were price-takers and trading pairs faced one of three exogenously imposed trading prices. The...

The Gini coefficient features prominently in Amartya Sen's 1973 and 1997 seminal work on income inequality and social welfare. We construct the Gini coefficient from social-psychological building blocks, reformulating it as a ratio between a measure of social stress and aggregate income. We...

Social stress can cause physical and mental harm. It is therefore not surprising that public health policy makers have sought to identify and implement policies aimed at tackling this social ill. A frequently prescribed remedy is to reduce social stress by reducing income inequality, which is...

We present a new index for measuring income inequality in networks. The index is based on income comparisons made by the members of a network who are linked with each other by direct social connections. To model the comparisons, we compose a measure of relative deprivation for networks. We base...

Sen (1973 and 1997) presents the Gini coefficient of income inequality in a population as follows. "In any pair-wise comparison the man with the lower income can be thought to be suffering from some depression on finding his income to be lower. Let this depression be proportional to the...

The social stress experienced by an individual from having a low relative income or from having a low income-based rank is a derivative of the individual's location in social space, and is the outcome of unfavorable comparisons with other individuals in that space. (The term social space stands...

We present and test the idea that bequest planning is linked with the experience of inheriting. We consider "a family tradition of bequeathing" as a channel through which the intention to bequeath is molded by and is positively correlated with the experience of inheriting. We use data from the...
