One of the most influential and unexpected economic luminaries of his time and the original value investor, John Maynard Keynes was a British economist whose ideas, called Keynesian economics, had a major impact on modern economic and political theory as well as on many governments' fiscal policies. Keynes explored new economic thoughts through speculating heavily in foreign markets and becoming one of the first proponents of investing in common stocks.Keynes was a world-changing economist who, almost uniquely among his professional brethren, also mastered the financial markets in practice. His theories uncannily prefigure those of Warren Buffett and other well-known value investors. He is particularly remembered for advocating interventionist government policy, by which the government would use fiscal and monetary measures to aim to mitigate the adverse effects of economic recessions, depressions, and books. Economists consider him one of the main founders of modern theoretical macroeconomics. This book sheds new light on both the personal and professional aspects of Keynes' life that helped shape his economic theories, and in turn, those of today's financial leaders by outlining Keynes' 6 key investment principles.
