Question: Were James Hanley and John Kenneth Galbraith authors?

full_context: Document 1: James Jones (author): James Ramon Jones (November 6, 1921 – May 9, 1977) was an American novelist known for his explorations of World War II and its aftermath. He won the 1952 National Book Award for his first published novel, "From Here to Eternity", which was adapted for the big screen immediately and made into a television series a generation later.
Document 2: John Kenneth Galbraith: John Kenneth "Ken" Galbraith, OC ( , October 15, 1908 – April 29, 2006) was a Canadian-born economist, public official, and diplomat, and a leading proponent of 20th-century American liberalism. His books on economic topics were bestsellers from the 1950s through the 2000s, during which time Galbraith fulfilled the role of public intellectual. As an economist, he leaned toward Post-Keynesian economics from an institutionalist perspective.
Document 3: James Hanley (novelist): James (Joseph) Hanley (3 September 1897 – 11 November 1985) was a British novelist, short story writer, and playwright of Irish descent. He published his first novel "Drift" in 1930. The novels and short stories about seamen and their families that he wrote in the 1930s and 1940s included "Boy" (1931), the subject of an obscenity trial. Hanley came from a seafaring family and spent two years at sea himself. After World War II there was less emphasis on the sea in his works. While frequently praised by critics, Hanley's novels did not sell well. In the late 1950s, 1960s, and early 1970s he wrote plays, mainly for the BBC, for radio and then for television, and also for the theatre. He returned to the novel in the 1970s. His last novel, "A Kingdom", was published in 1978, when he was eighty.

Document 7: Economics and the Public Purpose: Economics and the Public Purpose is a 1973 book by Harvard economist John Kenneth Galbraith. Galbraith advocates a "new socialism" as the solution, nationalising military production and public services such as health care. He also advocates introducing disciplined wage, salary, profit and price controls on the economy to reduce inequality and restrain the power of giant corporations. Socialisation of the "unduly weak industries and unduly strong ones" together with planning for the remainder would allow the public interest to be accorded its rightful preference, argues Galbraith, over private interests. He adds that this can only be achieved when there is a new belief system that rejects the orthodoxy of economics in the past. The new socialism needs to be achieved through gradual democratic political change.

Document 13: PEN/John Kenneth Galbraith Award: The PEN/John Kenneth Galbraith Award for nonfiction is awarded by the PEN American Center biennially "to a distinguished book of general nonfiction possessing notable literary merit and critical perspective and illuminating important contemporary issues which has been published in the United States during the previous two calendar years. It is intended that the winning book possess the qualities of intellectual rigor, perspicuity of expression, and stylistic elegance conspicuous in the writings of author and economist John Kenneth Galbraith, whose four dozen books and countless other publications continue to provide an important and incisive commentary on the American social, intellectual and political scene."
Document 14: American Capitalism: American Capitalism - The Concept of Countervailing Power is a book by John Kenneth Galbraith, written in 1952. It contains a critique of the view that markets, left to their own devices, will provide socially optimal solutions. Galbraith agrees with F. A. Hayek as far as the assertion goes that "the price system will fulfil [its] function only if competition prevails, that is, if the individual producer has to adapt to price changes and cannot control them." The book presents Galbraith's account of the inter-relationship between politics and economics which for Galbraith is based on a theory of competition guiding a capitalistic democratic society.
Document 15: The Affluent Society: The Affluent Society is a 1958 (4th edition revised 1984) book by Harvard economist John Kenneth Galbraith. The book sought to clearly outline the manner in which the post-World War II United States was becoming wealthy in the private sector but remained poor in the public sector, lacking social and physical infrastructure, and perpetuating income disparities. The book sparked much public discussion at the time. It is also credited with popularizing the term "conventional wisdom." Many of the ideas presented were later expanded and refined in Galbraith's 1967 book, "The New Industrial State".
