Laffer curve would raise taxable income enough so that the annual total tax revenue would be higher within five years than without the tax cut", none of the economists surveyed agreed and 71% disagreed. One of the conceptual uses of the Laffer curve is to determine the rate of taxation that will raise the maximum revenue (in other words, "optimizing" revenue collection). The revenue maximizing tax rate should not be confused with the optimal tax rate, which economists use to describe tax rates in a tax system that raises a given amount of revenue with the least distortions to the economy. The
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
