The news these days from Africa isn’t all bad. In fact, in some places, it’s downright hopeful, as Rwandan President Paul Kagame (b. 1957) attests. “Our continent is no longer all about violence and disease and human disasters that scarred many African countries in recent decades,” says Kagame. “We are now becoming a continent of opportunities.” There are those who doubted Rwanda could “constitute a viable state,” says Kagame, but 14 years after bloody genocide and civil war, his country has managed an astonishing revival.

Robert M. Solow (b. 1924) is considered to be one of the founders of modern neoclassical economics. He utilized determinants of economic growth to be separated out into increases in inputs and technical progress. Using his model, he calculated that about four-fifths of the growth in U.S. output per worker was attributable to technical progress. Solow also was the first to develop a growth model with different vintages of capital.
