History of economic thought voting procedures; he developed the theory with Eric Maskin (1950–) and Roger Myerson (1951–), sharing the 2007 Nobel Economics Prize with them. In 1974 American economist Arthur Laffer formulated the Laffer Curve, which postulates that no tax revenue will be raised at the extreme tax rates of 0% and 100%, and that there must be at least one rate where tax revenue would be a non-zero maximum. This concept was adopted by U.S. President Ronald Reagan in the early 1980s, becoming the cornerstone of Reaganomics, which was co-founded by American economist Paul Craig Roberts.

Optimal foraging theory items that an animal should carry back to its nesting site or the optimal size of a food item that an animal should feed on. Figure 1, shows an example of how an optimal decision rule could be determined from a graphical model. The curve represents the energy gain per cost (E) for adopting foraging strategy x. Energy gain per cost is the currency being optimized. The constraints of the system determine the shape of this curve. The optimal decision rule (x*) is the strategy for which the currency, energy gain per costs, is the greatest. Optimal foraging models can
