The term "resource curse phenomenon" refers to countries with an abundance of natural resources, in particular nonrenewable ones such as minerals or fuels, that tend to have less economic growth and worst development than other countries with fewer resources. Starting from a work of 2006 we extended and developed two models, the first nonevolutive and the second a discrete-time one, to analyze graphically and numerically how resources, population and in particular institutions are related with market prices. This work is part of my PhD thesis and it is with the advice of Italo Capuzzo Dolcetta.
