Risk Equity Prices and Excess Return

We noted above that, at least in the United Kingdom and the United States, the rate of return on equities over the last 100 years had, on average, substantially exceeded the rate of return available on government bonds. This makes perfect sense as long as the risk on equities substantially exceeds the risk of those other investments. But what do we mean by risk here, and how might we measure it The answer to these questions matters a lot, because movements in the risk premium can dramatically...

Future dividends should influence todays stock price

However, note that while the current stock price reflects information about all future dividends, all dividends are not equally important. Because of discounting, current dividends influence the current stock price more than dividends in the far future. The discounting works as follows. The current stock price depends on the discounted expected price and dividends next period, P(0) P(1) + D(1) (1 + r). We also know that next period's price equals the discounted value of expected prices and...

Comparative advantage means that all countries can benefit from free trade even if they are characterized by low levels

The theory of comparative advantage says that all countries can benefit from trade. However, there are some things comparative advantage does not imply (a) Comparative advantage says all countries gain from trade, but not that all countries become wealthy. As we saw in Chapters 3 though 6, the standard of living in a country depends on its absolute productivity. In our example, Eurasia is more productive than Oceania and so has a better standard of living (compare the level of onions per capita...

Demographic Influences in the Life Cycle Model

We have omitted much of the richness of individual lives in the simple two period models that we looked at earlier in this chapter. But this richness affects both consumption and savings. The profile of income over individual lives is likely to be uneven and, as a consequence, we can expect people's savings behavior to be different at different points in 12.9 Demographic Influences in the Life Cycle Model 315 their life cycle.Most people earn low amounts in their teens and often into their...

Are Stock Prices Forecastable

Belief in efficient (or rational) stock market pricing has taken big blows over the last 20 years. Robert Shiller led the intellectual assault on belief in stock market efficiency in a series of papers written more than 20 years ago.10 In 1981 Shiller argued that stock prices in the United States over the 100-year period starting in 1870 were far too volatile to be consistent with a rational evaluation of the fundamental value of the corporate sector.11 Shiller wanted to compare the volatility...

Public Goods And Nasty Nash Equilibria

Most people who have read Joseph Heller's Catch-22 remember the catch if you were crazy, you could be declared unfit to fly dangerous bombing raids, but claiming insanity to avoid flying is the act of a sane man. In one of the scenes in the novel, a character is discovered committing a selfish act that could endanger others and is asked, What if everyone did that After some thought, he answers, Then I'd be a fool not to. Economists will instantly recognize a Nash equilibrium here (named after...
