If productive capacity grows, an economy can produce progressively more goods, which raises the standard of living . The increase in productive capacity of an economy is called economic growth . There are various factors affecting economic growth. The problems of economic growth have been discussed by numerous growth models, including the Harrod-Domar model, the neoclassical growth models of Solow and Swan, and the Cambridge growth models of Kaldor and Joan Robinson. This part of economic problem is studied in the economies of development.
Discussion of what eventually came to be called basic income began with scattered writers in Britain and the United States in the first half of the twentieth century. The idea gained strength in United States and Canada in the 1960s and 1970s, not least among economists, but disappeared from the political scene in the 1980s (when the politicians chose to implement the Earned Income Tax Credit instead). In the 1980s, however, the discussion had also begun in Europe. It was a somewhat fringe debate in the beginning, but it continued and grew gradually in the 1980s, 1990s, and 2000s. Following the 2009 financial crisis, basic income has seen a significant rise in prominence around the world. The debate has now broadened to most of the developed world, to Latin America, Middle East, and to at least some countries in Africa and Asia. Several countries are also preparing or are already running basic income pilots. [ citation needed ]
