Malthus wrote The Grounds of an Opinion on the Policy of Restricting the Importation of Foreign Corn in 1815. He had presented his opinion on Corn Laws in England the previous year, deciding that free trade should be upheld. Yet, in this treatise, he reasons that some restrictions are of value. Malthus is known for his theories on the effect of population growth on an economy. THOMAS ROBERT MALTHUS (1766-1834) was an English classical economist, educated at Jesus College in Cambridge. In 1798, he took orders as a curate at Albury in Surrey, and became a Professor of History and Political Economy at the East India Company College (now known as Haileybury) in 1805. His most notable work is An Essay on the Principle of Population, with six editions published between 1798 to 1826.
