Hans Singer was a prominent economist known for his contributions to development economics. Born in 1910 in Germany, he later moved to the United Kingdom, where he became a key figure in international economic discussions. His work focused on the challenges faced by developing countries and the importance of fair trade practices. One of his notable contributions is the Singer-Prebisch thesis, which argues that the terms of trade for developing countries tend to deteriorate over time. This idea has influenced policies aimed at improving economic conditions in the Global South and remains relevant in discussions about global inequality and trade relations.
