Political debates about the United States federal budget concentration of income at the top of the income distribution." In theory, the government collects no revenue at either zero or 100% tax rates. So there is some intermediate point at which government revenue is maximized. Lowering tax rates from 100% to this hypothetical rate that maximizes revenue would theoretically raise revenue, while continuing to lower tax rates below this rate would lower revenues. This concept underlies the Laffer Curve, an element of supply-side economics. Since the 1970s, some "supply side" economists have contended that lowering marginal tax rates could stimulate economic growth to such a degree that tax revenues
Keeling Curve Keeling Curve The Keeling Curve is a graph of the accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day. The curve is named for the scientist Charles David Keeling, who started the monitoring program and supervised it until his death in 2005. Keeling's measurements showed the first significant evidence of rapidly increasing carbon dioxide levels in the atmosphere. According to Dr Naomi Oreskes, Professor of History of Science at Harvard University, the Keeling curve is one of the most important
