Optimal tax tax rates are lowered, revenue will be decrease by the same amount—and an economic effect—which provides incentives for individuals to increase their work output through low tax rates. These correspond to the mechanical and behavioural effects discussed by Saez. The Laffer Curve illustrates that, for sufficiently high tax levels, the (negative) behavioural effect will outweigh the (positive) mechanical effect of a tax increase, and so increasing tax rates will reduce tax revenue. In fact, tax revenue with a tax rate of 100% is likely to be 0, since there is no remaining incentive to work at all. Therefore, the tax
The J Curve (book) The J Curve (book) The J Curve: A New Way to Understand Why Nations Rise and Fall (Simon & Schuster: 2006) is a book by political scientist Ian Bremmer. It was named a "Book of the Year" in 2006 by "The Economist". Bremmer's J Curve describes the relationship between a country's openness and its stability; focusing on the notion that while many countries are stable because they are open (the United States, France, Japan), others are stable because they are closed (North Korea, Cuba, Iraq under Saddam Hussein). According to Bremmer, a government's motivations differ dramatically depending on where they
