P reface CR A Long time ago, a visitor from out of town came to a tour in Manhattan. At the end of the tour they took him to the financial district. When they arrived to Battery park the guide showed him some nice yachts anchoring there, and said, here are the yachts of our bankers and stockbrokers. And where are the yachts of the investors? asked the naive visitor
A long time ago, a visitor from out of town came to a tour in Manhattan. At the end of the tour they took him to the financial district. When they arrived to Battery Park the guide showed him some nice yachts anchoring there, and said, "Here are the yachts of our bankers and stockbrokers." "And where are the yachts of the investors?" asked the naive visitor. Preface
Investment c& Investment decisions are intertemporal choices involvin g tradeoffs among costs and benefits occurring at different times, which not only affect one 's health, wealth, and happiness, but may also determine the economic prosperity of nations CR Fisher(1930): investment is not an end in itself but rather a process for distributing consumption over time cR Major concerns: return, risk, information acquisition, life cycle, liquidity constraint, risk preference, background risk, etc
