Voluntary exchange is the act of buyers and sellers freely and willingly engaging in market transactions. Moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred.

Many economists believe that voluntary exchanges are more conducive to economic efficiency than exchanges mandated by governments.

Walter E. Williams, (born March 31, 1936) is an American economist, commentator, and academic. He is the John M. Olin Distinguished Professor of Economics at George Mason University, as well as a syndicated columnist and author known for his libertarian views.

Williams was born into an African-American family. His family during childhood consisted of himself, his mother, and his sister. His father played no role in raising either child. He grew up in Philadelphia. The family initially lived in West Philadelphia, moving to North Philadelphia and the Richard Allen housing projects when Williams was ten. His neighbors included a young Bill Cosby. Williams knew many of the individuals that Cosby speaks of from his childhood, including Weird Harold and Fat Albert.

Williams was a talented high school student who displayed a very inconsistent performance in his studies. Following high school he came out to stay with his father in California, and attended one semester at Los Angeles City College, in regard to which he would later state that he was not ready yet to be a serious student. In 1959 he was drafted into the military, and served as a Private in the United States Army.

Ayn Rand ( /ˈaɪn ˈrænd/; born Alisa Zinov'yevna Rosenbaum, February 2 [O.S. January 20] 1905 – March 6, 1982) was a Russian-American novelist, philosopher, playwright, and screenwriter. She is known for her two best-selling novels The Fountainhead and Atlas Shrugged and for developing a philosophical system she called Objectivism.

Born and educated in Russia, Rand moved to the United States in 1926. She worked as a screenwriter in Hollywood and had a play produced on Broadway in 1935–1936. After two initially unsuccessful early novels, she achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-known work, the philosophical novel Atlas Shrugged. Afterward she turned to nonfiction to promote her philosophy, publishing her own magazines and releasing several collections of essays until her death in 1982.

Rand advocated reason as the only means of acquiring knowledge and rejected all forms of faith and religion. She supported rational and ethical egoism, and rejected ethical altruism. In politics, she condemned the initiation of force as immoral and opposed all forms of collectivism and statism, instead supporting laissez-faire capitalism, which she believed was the only social system that protected individual rights. She promoted romantic realism in art. She was sharply critical of the philosophers and philosophical traditions known to her besides Aristotle.
