James Tobin
James Tobin (March 5, 1918 – March 11, 2002) was an American economist who served on the Council of Economic Advisers and the Board of Governors of the Federal Reserve System, and taught at Harvard and Yale Universities. He developed the ideas of Keynesian economics, and advocated government intervention to stabilize output and avoid recessions. His academic work included pioneering contributions to the study of investment, monetary and fiscal policy and financial markets. He also proposed an econometric model for censored endogenous variables, the well-known "Tobit model". Tobin received the Nobel Memorial Prize in Economic Sciences in 1981.
Joseph Butler
Joseph Butler (18 May 1692 – 16 June 1752) was an English bishop, theologian, apologist, and philosopher. He was born in Wantage in the English county of Berkshire (now Oxfordshire). He is known, among other things, for his critique of Deism, Thomas Hobbes's egoism, and John Locke's theory of personal identity. Butler influenced many philosophers and religious thinkers, including David Hume, Thomas Reid, Adam Smith, Henry Sidgwick, John Henry Newman, and C. D. Broad, and is widely considered "as one of the preeminent English moralists." He also played an important, though under appreciated, role in the development of eighteenth-century economic discourse, greatly influencing the Anglican Dean of Gloucester and political economist Josiah Tucker.
