This study deals with comparative statics of the consumer’s demand. According to Lancaster [1966, Journal of Political Economy ], a utility function should be defined on the set of all characteristics that affect well-being of the consumer and these characteristics should be derived by consuming commodities. We show the sufficient condition for monotone comparative statics of the demand for cha...

The easy access to large data sets has allowed for leveraging methodology in network physics and complexity science to disentangle patterns and processes directly from the data, leading to key insights in the behavior of systems. Here we use country specific food production data to study binary and weighted topological properties of the bipartite country-food production matrix. This country-foo...

This article discusses the appeal to infinite value in environmental decision making. We argue that invoking infinite values as a means of faithfully representing the worth of certain parts of the natural environment is a mistake. Infinite values have a number of theoretical and practical problems associated with them. For example, we show that invoking infinite values makes it hard to motivate...
