We model group formation as a response to relative deprivation. We employ two measures of relative deprivation. We show that in the case of each of these measures the process of deprivation-induced self-selection into groups reaches a steady state, and that the steady-state distribution differs...

This paper argues that an increase in the inequality of wealth prompts a stronger quest for status that in turn fosters the accumulation of wealth. It proposes a measure for an individual's want of social status. For a given level of a population's wealth, the corresponding aggregate measure of...

After many years of neglect, there is a renewed interest in agricultural mechanization in Africa. Since government initiatives to promote mechanization, e.g., by importing and subsidizing tractors, are confronted with major governance challenges, private-sector initiatives offer a promising...

A rationale for providing support to the farm sector in the course of economic development and structural change is a growing gap between the incomes of non-agricultural workers and the incomes of farmers. Drawing on a model that enables us to analyze the level of social stress experienced by...

Acknowledging individuals' distaste for low relative income renders trade less appealing when trade is viewed as a technology that integrates economies by merging separate social spheres into one. We define a “trembling trade” as a situation in which gains from trade are overtaken by losses...

We study the relative risk aversion of an individual with particular social preferences: his well-being is influenced by his relative wealth, and by how concerned he is about having low relative wealth. Holding constant the individual's absolute wealth, we obtain two results. First, if the...

Implementation of suitable innovation packages into cropping systems is required to address the issues of food security and improvement of the crop yield in Sub-Saharan Africa. However, quantification of the effects of innovation packages such as increase in fertilizer application rates,...

The water-energy-food security nexus concept is a widely recognized analytical approach to consider and achieve sustainable development goals. However, the water-energy-food security nexus concept has mostly been analyzed at higher scales in a top-down manner, while examples of bottom-up and...

The majority of rural Indian households remain dependent on unreliable, inefficient and harmful household energy technologies. Rural households make their energy decisions with respect to the Water-Energy-Food security (WEF) Nexus jointly, however, previous research initiatives have analyzed...

This paper examines whether investment in the agriculture and food sectors in Africa significantly increases overall economic growth and, hence, reduces food and nutrition insecurity. To this end, the study examines the causal link between agricultural growth, food production, quality of...
