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. In 1986 French economist Jean Tirole
Optimal foraging theory shown as a curve of energy gain per time spent in a patch (Figure 3). The curve starts off with a steep slope and gradually levels off as prey becomes harder to find. Another important cost to consider is the traveling time between different patches and the nesting site. An animal loses foraging time while it travels and expends energy through its locomotion. In this model, the currency being optimized is usually net energy gain per unit time. The constraints are the travel time and the shape of the curve of diminishing returns. Graphically, the currency (net energy gain per
